Messaging security is a subcategory of unified threat management (UTM) focused on securing and protecting an organization’s communication infrastructure. Communication channels can include email software, messaging apps, and social network IM platforms. This extra layer of security can help secure devices and block a wider range of viruses or malware attacks.
Messaging security helps to ensure the confidentiality and authenticity of an organization’s communication methods. Confidentiality refers to making sure only the intended recipients are able to read the messages and authenticity refers to making sure the identity of each sender or recipient is verified.
Oftentimes, attackers aim to gain access to an entire network or system by infiltrating the messaging infrastructure. Implementing proper data and message security can minimize the chance of data leaks and identity theft.
Encrypted messaging (also known as secure messaging) provides end-to-end encryption for user-to-user text messaging. Encrypted messaging prevents anyone from monitoring text conversations. Many encrypted messenger apps also offer end-to-end encryption for phone calls made using the apps, as well as for files that are sent using the apps.
Two modern methods of encryption are the Public Key (Asymmetric) and the Private Key (Symmetric) methods. While these two methods of encryption are similar in that they both allow users to encrypt data to hide it from the prying eyes of outsiders and then decrypt it for viewing by an authorized party, they differ in how they perform the steps involved in the process.
Email security message can rely on public-key cryptography, in which users can each publish a public key that others can use to encrypt messages to them, while keeping secret a private key they can use to decrypt such messages or to digitally encrypt and sign messages they send.
Encrypted messaging systems must be encrypted end-to-end, so that even the service provider and its staff are unable to decipher what’s in your communications. Ideal solutions is “server-less” encrypted chat where companies won’t store user information anywhere.
In a more general sense, users of unsecured public Wi-Fi should also consider using a Virtual Private Network (VPN) application, to conceal their identity and location from Internet Service Providers (ISPs), higher level surveillance, and the attentions of hackers.

F.A.Q about Messaging Security
What is messaging security?
Messaging Security is a program that provides protection for companies' messaging infrastructure. The programs include IP reputation-based anti-spam, pattern-based anti-spam, administrator-defined block/allow lists, mail antivirus, zero-hour malware detection, and email intrusion prevention.
Six Dimensions of Comprehensive Messaging Security
- IP-Reputation Anti-spam. It checks each email connection request with a database of IP addresses to establish whether a sender is a legitimate or known spam sender and malware. If a sender is recognized it undesirable the messaging Security program drops the connection before the message is accepted.
- Pattern-based anti-spam utilizes a proprietary algorithm to establish a fingerprint-like signature of email messages. When a message comes in, its pattern is calculated and checked against a database to determine if the message matches a known email pattern.
- Block/Allow List Anti-spam. Administrators can create a list of IP addresses or domains that they would like to either block or allow. This method ensures that trusted sources are explicitly allowed and unwanted sources are explicitly denied access.
- Mail Antivirus. This layer of protection blocks a wide range of known viruses and malware attacks.
- Zero-Hour Malware Protection. By analyzing large numbers of messages, outbreaks are detected along with their corresponding messages. These message patterns are then flagged as malicious, giving information about a given attack.
- SmartDefense Email IPS. The messaging security program utilizes SmartDefense Email IPS to stop attacks targeting the messaging infrastructure.
What are Signal, Wire and LINE messenger security apps like ?
Secure private messenger is a messaging application that emphasizes the privacy and of users using encryption and service transparency. While every modern messenger system is using different security practices (most prominently SSL/HTTPS) - the difference between secure and classic messengers is what we don’t know in the scope of implementation and approach to user data.
Message access control and secure messengers evolved into a distinct category due to the growing awareness that communication over the internet is accessible by third parties, and reasonable concerns that the messages can be used against the users.
Why secure communication is essential for business?
In the context of business operation, communication is a vital element of maintaining an efficient and dynamic working process. It lets you keep everything up to date and on the same page. And since many things are going on at the same time - tools like messengers are one of the many helpers that make the working day a little more manageable.
Some of the information, like employee and customer data, proprietary information, data directly linked to business performance or future projections, may be strictly under a non-disclosure agreement. Without proper text message authentication in information security or encryption, it remains vulnerable to exposure. The chances are slim, but the possibility remains.
And there are people interested in acquiring that sensitive information, people who like to play dirty because getting a competitive advantage is a decent motivation to go beyond the law. And when private conversations leak, especially the business-related ones - the impact is comparable with the Titanic hitting an iceberg.
Encrypted massages in messenger prevents this from happening.
