Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. Currently, encryption is one of the most popular and effective data security methods used by organizations. \r\nTwo main types of data encryption exist - <span style=\"font-weight: bold;\">asymmetric encryption</span>, also known as public-key encryption, and <span style=\"font-weight: bold;\">symmetric encryption</span>.<br />The purpose of data encryption is to protect digital data confidentiality as it is stored on computer systems and transmitted using the internet or other computer networks. The outdated data encryption standard (DES) has been replaced by modern encryption algorithms that play a critical role in the security of IT systems and communications.\r\nThese algorithms provide confidentiality and drive key security initiatives including authentication, integrity, and non-repudiation. Authentication allows for the verification of a message’s origin, and integrity provides proof that a message’s contents have not changed since it was sent. Additionally, non-repudiation ensures that a message sender cannot deny sending the message.\r\nData protection software for data encryption can provide encryption of devices, email, and data itself. In many cases, these encryption functionalities are also met with control capabilities for devices, email, and data. \r\nCompanies and organizations face the challenge of protecting data and preventing data loss as employees use external devices, removable media, and web applications more often as a part of their daily business procedures. Sensitive data may no longer be under the company’s control and protection as employees copy data to removable devices or upload it to the cloud. As a result, the best data loss prevention solutions prevent data theft and the introduction of malware from removable and external devices as well as web and cloud applications. In order to do so, they must also ensure that devices and applications are used properly and that data is secured by auto-encryption even after it leaves the organization.\r\nEncryption software program encrypts data or files by working with one or more encryption algorithms. Security personnel use it to protect data from being viewed by unauthorized users.\r\nTypically, each data packet or file encrypted via data encryption programs requires a key to be decrypted to its original form. This key is generated by the software itself and shared between the data/file sender and receiver. Thus, even if the encrypted data is extracted or compromised, its original content cannot be retrieved without the encryption key. File encryption, email encryption, disk encryption and network encryption are widely used types of data encryption software.<br /><br />","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What is Encryption software?</span></h1>\r\nEncryption software is software that uses cryptography to prevent unauthorized access to digital information. Cryptography is used to protect digital information on computers as well as the digital information that is sent to other computers over the Internet.There are many software products which provide encryption. Software encryption uses a cipher to obscure the content into ciphertext. One way to classify this type of software is by the type of cipher used. Ciphers can be divided into two categories: <span style=\"font-weight: bold;\">public key ciphers</span> (also known as asymmetric ciphers), and <span style=\"font-weight: bold;\">symmetric key ciphers</span>. Encryption software can be based on either public key or symmetric key encryption.\r\nAnother way to classify crypto software is to categorize its purpose. Using this approach, software encryption may be classified into software which encrypts &quot;<span style=\"font-weight: bold;\">data in transit</span>&quot; and software which encrypts &quot;<span style=\"font-weight: bold;\">data at rest</span>&quot;. Data in transit generally uses public key ciphers, and data at rest generally uses symmetric key ciphers.\r\nSymmetric key ciphers can be further divided into stream ciphers and block ciphers. Stream ciphers typically encrypt plaintext a bit or byte at a time, and are most commonly used to encrypt real-time communications, such as audio and video information. The key is used to establish the initial state of a keystream generator, and the output of that generator is used to encrypt the plaintext. Block cipher algorithms split the plaintext into fixed-size blocks and encrypt one block at a time. For example, AES processes 16-byte blocks, while its predecessor DES encrypted blocks of eight bytes.<br />There is also a well-known case where PKI is used for data in transit of data at rest.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">How Data Encryption is used?</span></h1>\r\nThe purpose of data encryption is to deter malicious or negligent parties from accessing sensitive data. An important line of defense in a cybersecurity architecture, encryption makes using intercepted data as difficult as possible. It can be applied to all kinds of data protection needs ranging from classified government intel to personal credit card transactions. Data encryption software, also known as an encryption algorithm or cipher, is used to develop an encryption scheme which theoretically can only be broken with large amounts of computing power.\r\nEncryption is an incredibly important tool for keeping your data safe. When your files are encrypted, they are completely unreadable without the correct encryption key.&nbsp; If someone steals your encrypted files, they won’t be able to do anything with them.\r\nThere different types of encryption: hardware and software. Both offer different advantages. So, what are these methods and why do they matter?\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Software Encryption</span></h1>\r\n<p class=\"align-left\">As the name implies, software encryption uses features of encryption software to encrypt your data. Cryptosoft typically relies on a password; give the right password, and your files will be decrypted, otherwise they remain locked. With encryption enabled, it is passed through a special algorithm that scrambles your data as it is written to disk. The same software then unscrambles data as it is read from the disk for an authenticated user.</p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Pros.</span>Crypto programs is typically quite cheap to implement, making it very popular with developers. In addition, software-based encryption routines do not require any additional hardware.<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Cons.</span>Types of encryption software is only as secure as the rest of your computer or smartphone. If a hacker can crack your password, the encryption is immediately undone.<br />Software encryption tools also share the processing resources of your computer, which can cause the entire machine to slow down as data is encrypted/decrypted. You will also find that opening and closing encrypted files is much slower than normal because the process is relatively resource intensive, particularly for higher levels of encryption</p>\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Hardware encryption</span></h1>\r\n<p class=\"align-left\">At the heart of hardware encryption is a separate processor dedicated to the task of authentication and encryption. Hardware encryption is increasingly common on mobile devices. <br />The encryption protection technology still relies on a special key to encrypt and decrypt data, but this is randomly generated by the encryption processor. Often times, hardware encryption devices replace traditional passwords with biometric logons (like fingerprints) or a PIN number that is entered on an attached keypad<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Pros.</span>Hardware offers strong encryption, safer than software solutions because the encryption process is separate from the rest of the machine. This makes it much harder to intercept or break. </p>\r\n<p class=\"align-left\">The use of a dedicated processor also relieves the burden on the rest of your device, making the encryption and decryption process much faster.<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">Cons.</span>Typically, hardware-based encrypted storage is much more expensive than a software encryption tools. <br />If the hardware decryption processor fails, it becomes extremely hard to access your information.<span style=\"font-weight: bold;\"></span></p>\r\n<p class=\"align-left\"><span style=\"font-weight: bold;\">The Data Recovery Challenge. </span>Encrypted data is a challenge to recover. Even by recovering the raw sectors from a failed drive, it is still encrypted, which means it is still unreadable. </p>\r\n<p class=\"align-left\">Hardware encrypted devices don’t typically have these additional recovery options. Many have a design to prevent decryption in the event of a component failure, stopping hackers from disassembling them. The fastest and most effective way to deal with data loss on an encrypted device is to ensure you have a complete backup stored somewhere safe. For your PC, this may mean copying data to another encrypted device. For other devices, like your smartphone, backing up to the Cloud provides a quick and simple economy copy that you can restore from. As an added bonus, most Cloud services now encrypt their users’ data too. <br /><br /><br /></p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Data_Encryption.png","alias":"data-encryption"},"205":{"id":205,"title":"NAC - Network Access Control","description":"<span style=\"font-weight: bold; \">Network Access Control (NAC)</span> is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement. NAC solutions have become an extremely valuable tool in recent years, as mobile devices and the Internet of Things (IoT) have surged to prominence in various industries across the world. These new pieces of emerging technology come with their own set of vulnerabilities, which poses a challenge to IT security experts. \r\nNAC systems are put into place to make sure that anyone who enters the system, both in terms of users and devices, is authorized. After being routed the efforts at connection, the network access control system confirms privileges using an identity and access management (IAM, a program that checks users for appropriate permissions to access data materials, as indicated by internal policies). With the information from the IAM, along with a pre-established list of rules, the NAC software is able to smartly accept or deny access requests.\r\nFortunately, NAC products are designed to handle large enterprise networks that have a range of device types trying to connect at all times. Without a NAC in place, companies take on a huge amount of risk by adopting a bring-your-own-device (BYOD) policy, which allows employees and vendors to use their own smartphones and tablets on the local network. Network access control software and hardware require an upfront investment but prove their worth in the long run.","materialsDescription":"<h1 class=\"align-center\">&nbsp;How a NAC solution works?</h1>\r\nWhen you adopt a network access control solution, the first thing it will do is find all devices currently accessing the system; identify what kind of device they are; and determine whether to validate them and how to treat them using preestablished protocols designed by the company’s security personnel. A network access control system has rules related to a wide spectrum of devices, along with finely grained settings to help you determine permissions. A unified administrative system houses these rules and applies them as needed.\r\nMany companies will utilize NAC as their staff grows and they have an increasing number of devices to manage. These solutions are also helpful for achieving data protection across a variety of different branch locations. The difficulty of securing an organization and managing access has become especially overwhelming in an era when widespread incorporation of IOT devices is becoming more common throughout business; NAC is the fix. The general issue with bring your own device (BYOD), though, is what drew many businesses to this service.\r\n<h1 class=\"align-center\">How to Choose a Network Access Control Solution</h1>\r\nTo help narrow down your search for NAC products, you should first focus on tools that offer native integration with your enterprise’s existing software. You don’t want to have to change your infrastructure or network design in order to bring the NAC solution online. If you are heavily dependent on a cloud architecture, then look for solutions that are fully supported by your hosting provider.\r\nNext, think about what kind of proactive tools come included with the NAC suite. Some vendors offer all-in-one packages that feature a full virus scanning utility and firewall mechanism alongside everything else in the NAC. If your IT security strategy is not very mature, this kind of suite may be very helpful.\r\nOf course, one key factor when looking at NAC options is the price point. Some vendors will sell their products at a flat rate, while others are quickly going the route of Software as a Service (SaaS) subscription, an increasingly-popular business model that requires a monthly payment and ongoing contract. Think about the state of your IT budget while remembering that the upfront investment could save you lots of money down the road.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/NAC_-_Network_Access_Control__1_.png","alias":"nac-network-access-control"},"375":{"id":375,"title":"Mobile Enterprise Security","description":" Because mobile devices are easily lost or stolen, data on those devices is vulnerable. Enterprise mobility management is a set of systems intended to prevent unauthorized access to enterprise applications and/or corporate data on mobile devices. These can include password protection, encryption and/or remote wipe technology, which allows an administrator to delete all data from a misplaced device. With many systems, security policies can be centrally managed and enforced. Such device management systems are programmed to support and cooperate with the application programming interfaces (APIs) from various device makers to increase security compliance.\r\nThe data transfer between mobile device and the enterprise should always be encrypted, for example through a VPN tunnel or over HTTPS.\r\nMobile devices in companies with &quot;bring your own device&quot; (BYOD) policies are often used both personally and professionally. In these cases, corporate IT has less control over whether malware is on the device and what damage may be caused to corporate data. Apart from careful user behavior - data storage on the mobile device should be limited and centrally organized.","materialsDescription":" <span style=\"font-weight: bold;\">What is mobile security?</span>\r\nMobile security refers to the set of technologies and practices that aim to protect mobile devices against operating system vulnerabilities, network and app attacks, or mobile malware. Technologies such as enterprise mobility management (EMM) solutions manage compliance policies and issues relating to device privilege or loss.\r\n<span style=\"font-weight: bold;\">What are mobile security threats?</span>\r\nMobile security threats are vulnerabilities or attacks that attempt to compromise your phone's operating system, internet connection, Wi-Fi and Bluetooth connections, or apps. Smartphones possess very different behaviors and capabilities compared to PCs or laptops and need to be equipped to detect attacks specific to mobile devices. Mobile devices contain unique functions and behaviors making traditional IT security solutions ineffective for securing mobile devices. One of the primary differences in how mobile devices are different from PCs and laptops is administration privileges. There are several administrators for a PC or laptop making it simple for corporate IT to install security software and monitor computers for problems. On mobile devices, the administration is handled by the device owner. The device owner is the only one that can install apps or allow other management profiles on the device. This means the burden of securing the mobile device and its data falls entirely on the user--who may not have the time or expertise to provide proper mobile device security.\r\n<span style=\"font-weight: bold;\">Why is mobile security important?</span>\r\nMobile security is very important since our mobile device is now our primary computing device. On average, users spend more than 5 hours each day on a mobile device conducting company and personal business. The shift in device usage habits has also moved the prime target for hackers from PCs to our mobile devices. Since mobile devices are now a prime target, we need to secure them and arm them with threat detection and malware protection just like PCs. Smartphones are able to circumvent traditional security controls, and typically represent a massive blind spot for IT and security teams. Hackers know this, which no doubt contributed to the number of smartphone attacks recorded between January and July 2016. The number of attacks nearly doubled compared to the last six months of 2015. During that same time period, smartphones accounted for 78% of all mobile network infections.\r\n<span style=\"font-weight: bold;\">Which mobile security is best for enterprises?</span>\r\nThere are a number of mobile security solutions available on the market, but identifying which mobile security is best for enterprises entails using specific criteria. As is often the case, solutions designed for consumers and end-users may not be as robust, full-featured, reliable and scalable as solutions designed specifically for the enterprise. In particular, mobile security solutions that are suitable for enterprise use should include scalability, autonomous functionality, machine learning, on-device operation, and protection from zero-day threats. Enterprises also need to consider flexible deployment models to take advantage of existing infrastructure or cloud computing environments.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Mobile_Enterprise_Security.png","alias":"mobile-enterprise-security"},"834":{"id":834,"title":"IoT - Internet of Things Security","description":" IoT security is the technology area concerned with safeguarding connected devices and networks in the internet of things (IoT).\r\nIoT involves adding internet connectivity to a system of interrelated computing devices, mechanical and digital machines, objects, animals and/or people. Each &quot;thing&quot; is provided a unique identifier and the ability to automatically transfer data over a network. Allowing devices to connect to the internet opens them up to a number of serious vulnerabilities if they are not properly protected.\r\nIoT security has become the subject of scrutiny after a number of high-profile incidents where a common IoT device was used to infiltrate and attack the larger network. Implementing security measures is critical to ensuring the safety of networks with IoT devices connected to them.\r\nIoT security hacks can happen in any industry, from smart home to a manufacturing plant to a connected car. The severity of impact depends greatly on the individual system, the data collected and/or the information it contains.\r\nAn attack disabling the brakes of a connected car, for example, or on a connected health device, such as an insulin pump hacked to administer too much medication to a patient, can be life-threatening. Likewise, an attack on a refrigeration system housing medicine that is monitored by an IoT system can ruin the viability of a medicine if temperatures fluctuate. Similarly, an attack on critical infrastructure -- an oil well, energy grid or water supply -- can be disastrous.\r\nSo, a robust IoT security portfolio must allow protecting devices from all types of vulnerabilities while deploying the security level that best matches application needs. Cryptography technologies are used to combat communication attacks. Security services are offered for protecting against lifecycle attacks. Isolation measures can be implemented to fend off software attacks. And, finally, IoT security should include tamper mitigation and side-channel attack mitigation technologies for fighting physical attacks of the chip.","materialsDescription":" <span style=\"font-weight: bold;\">What are the key requirements of IoT Security?</span>\r\nThe key requirements for any IoT security solution are:\r\n<ul><li>Device and data security, including authentication of devices and confidentiality and integrity of data</li><li>Implementing and running security operations at IoT scale</li><li>Meeting compliance requirements and requests</li><li>Meeting performance requirements as per the use case</li></ul>\r\n<span style=\"font-weight: bold;\">What do connected devices require to participate in the IoT Securely?</span>\r\nTo securely participate in the IoT, each connected device needs a unique identification – even before it has an IP address. This digital credential establishes the root of trust for the device’s entire lifecycle, from initial design to deployment to retirement.\r\n<span style=\"font-weight: bold;\">Why is device authentication necessary for the IoT?</span>\r\nStrong IoT device authentication is required to ensure connected devices on the IoT can be trusted to be what they purport to be. Consequently, each IoT device needs a unique identity that can be authenticated when the device attempts to connect to a gateway or central server. With this unique ID in place, IT system administrators can track each device throughout its lifecycle, communicate securely with it, and prevent it from executing harmful processes. If a device exhibits unexpected behavior, administrators can simply revoke its privileges.\r\n<span style=\"font-weight: bold;\">Why is secure manufacturing necessary for IoT devices?</span>\r\nIoT devices produced through unsecured manufacturing processes provide criminals opportunities to change production runs to introduce unauthorized code or produce additional units that are subsequently sold on the black market.\r\nOne way to secure manufacturing processes is to use hardware security modules (HSMs) and supporting security software to inject cryptographic keys and digital certificates and to control the number of units built and the code incorporated into each.\r\n<span style=\"font-weight: bold;\">Why is code signing necessary for IoT devices?</span>\r\nTo protect businesses, brands, partners, and users from software that has been infected by malware, software developers have adopted code signing. In the IoT, code signing in the software release process ensures the integrity of IoT device software and firmware updates and defends against the risks associated with code tampering or code that deviates from organizational policies.\r\nIn public key cryptography, code signing is a specific use of certificate-based digital signatures that enables an organization to verify the identity of the software publisher and certify the software has not been changed since it was published.\r\n<span style=\"font-weight: bold;\">What is IoT PKI?</span>\r\nToday there are more things (devices) online than there are people on the planet! Devices are the number one users of the Internet and need digital identities for secure operation. As enterprises seek to transform their business models to stay competitive, rapid adoption of IoT technologies is creating increasing demand for Public Key Infrastructures (PKIs) to provide digital certificates for the growing number of devices and the software and firmware they run.\r\nSafe IoT deployments require not only trusting the devices to be authentic and to be who they say they are, but also trusting that the data they collect is real and not altered. If one cannot trust the IoT devices and the data, there is no point in collecting, running analytics, and executing decisions based on the information collected.\r\nSecure adoption of IoT requires:\r\n<ul><li>Enabling mutual authentication between connected devices and applications</li><li>Maintaining the integrity and confidentiality of the data collected by devices</li><li>Ensuring the legitimacy and integrity of the software downloaded to devices</li><li>Preserving the privacy of sensitive data in light of stricter security regulations</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/iot.png","alias":"iot-internet-of-things-security"},"852":{"id":852,"title":"Network security","description":" Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: it secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.\r\nNetwork security starts with authentication, commonly with a username and a password. Since this requires just one detail authenticating the user name — i.e., the password—this is sometimes termed one-factor authentication. With two-factor authentication, something the user 'has' is also used (e.g., a security token or 'dongle', an ATM card, or a mobile phone); and with three-factor authentication, something the user 'is' is also used (e.g., a fingerprint or retinal scan).\r\nOnce authenticated, a firewall enforces access policies such as what services are allowed to be accessed by the network users. Though effective to prevent unauthorized access, this component may fail to check potentially harmful content such as computer worms or Trojans being transmitted over the network. Anti-virus software or an intrusion prevention system (IPS) help detect and inhibit the action of such malware. An anomaly-based intrusion detection system may also monitor the network like wireshark traffic and may be logged for audit purposes and for later high-level analysis. Newer systems combining unsupervised machine learning with full network traffic analysis can detect active network attackers from malicious insiders or targeted external attackers that have compromised a user machine or account.\r\nCommunication between two hosts using a network may be encrypted to maintain privacy.\r\nHoneypots, essentially decoy network-accessible resources, may be deployed in a network as surveillance and early-warning tools, as the honeypots are not normally accessed for legitimate purposes. Techniques used by the attackers that attempt to compromise these decoy resources are studied during and after an attack to keep an eye on new exploitation techniques. Such analysis may be used to further tighten security of the actual network being protected by the honeypot. A honeypot can also direct an attacker's attention away from legitimate servers. A honeypot encourages attackers to spend their time and energy on the decoy server while distracting their attention from the data on the real server. Similar to a honeypot, a honeynet is a network set up with intentional vulnerabilities. Its purpose is also to invite attacks so that the attacker's methods can be studied and that information can be used to increase network security. A honeynet typically contains one or more honeypots.","materialsDescription":" <span style=\"font-weight: bold;\">What is Network Security?</span>\r\nNetwork security is any action an organization takes to prevent malicious use or accidental damage to the network’s private data, its users, or their devices. The goal of network security is to keep the network running and safe for all legitimate users.\r\nBecause there are so many ways that a network can be vulnerable, network security involves a broad range of practices. These include:\r\n<ul><li><span style=\"font-weight: bold;\">Deploying active devices:</span> Using software to block malicious programs from entering, or running within, the network. Blocking users from sending or receiving suspicious-looking emails. Blocking unauthorized use of the network. Also, stopping the network's users accessing websites that are known to be dangerous.</li><li><span style=\"font-weight: bold;\">Deploying passive devices:</span> For instance, using devices and software that report unauthorized intrusions into the network, or suspicious activity by authorized users.</li><li><span style=\"font-weight: bold;\">Using preventative devices:</span> Devices that help identify potential security holes, so that network staff can fix them.</li><li><span style=\"font-weight: bold;\">Ensuring users follow safe practices:</span> Even if the software and hardware are set up to be secure, the actions of users can create security holes. Network security staff is responsible for educating members of the organization about how they can stay safe from potential threats.</li></ul>\r\n<span style=\"font-weight: bold;\">Why is Network Security Important?</span>\r\nUnless it’s properly secured, any network is vulnerable to malicious use and accidental damage. Hackers, disgruntled employees, or poor security practices within the organization can leave private data exposed, including trade secrets and customers’ private details.\r\nLosing confidential research, for example, can potentially cost an organization millions of dollars by taking away competitive advantages it paid to gain. While hackers stealing customers’ details and selling them to be used in fraud, it creates negative publicity and public mistrust of the organization.\r\nThe majority of common attacks against networks are designed to gain access to information, by spying on the communications and data of users, rather than to damage the network itself.\r\nBut attackers can do more than steal data. They may be able to damage users’ devices or manipulate systems to gain physical access to facilities. This leaves the organization’s property and members at risk of harm.\r\nCompetent network security procedures keep data secure and block vulnerable systems from outside interference. This allows the network’s users to remain safe and focus on achieving the organization’s goals.\r\n<span style=\"font-weight: bold;\">Why Do I Need Formal Education to Run a Computer Network?</span>\r\nEven the initial setup of security systems can be difficult for those unfamiliar with the field. A comprehensive security system is made of many pieces, each of which needs specialized knowledge.\r\nBeyond setup, each aspect of security is constantly evolving. New technology creates new opportunities for accidental security leaks, while hackers take advantage of holes in security to do damage as soon as they find them. Whoever is in charge of the network’s security needs to be able to understand the technical news and changes as they happen, so they can implement safety strategies right away.\r\nProperly securing your network using the latest information on vulnerabilities helps minimize the risk that attacks will succeed. Security Week reported that 44% of breaches in 2014 came from exploits that were 2-4 years old.\r\nUnfortunately, many of the technical aspects of network security are beyond those who make hiring decisions. So, the best way an organization can be sure that their network security personnel are able to properly manage the threats is to hire staff with the appropriate qualifications.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Network_security.png","alias":"network-security"}},"branches":"Information Technology","companySizes":"1 to 50 Employees","companyUrl":"https://circle-networks.com/","countryCodes":["DEU"],"certifications":[],"isSeller":true,"isSupplier":false,"isVendor":true,"presenterCodeLng":"","seo":{"title":"Circle Networks GmbH","keywords":"","description":" Circle Networks, founded January 2018, creates networking equipment that takes the burden of implementing security features away from the operator.
