Messengers have long been an integral part of every person's life, regardless of age or social status. This is an indispensable tool for correspondence, file sharing, video meetings and calls. And although there are many messengers offering convenient features, you should remember about the safety of your data.
Let's figure out what a secure messenger actually is and which of them can be considered reliable in 2025.
Safety first: the role and benefits of a secure messenger
What makes a secure messenger so special? Firstly, it offers encrypted messaging, meaning that the information being exchanged is protected from prying eyes. End-to-end encryption (E2EE) ensures the privacy of communications by ensuring that only the sender and receiver can read the contents of the messages.
However, a secure messenger is not limited to encryption alone. It may offer other useful features, such as multi-factor authentication for an extra layer of protection, the ability to self-destruct messages, screenshot control, and even storing data on secure servers. Some secure messengers are also open to audit and have open source code, which allows experts to check their security.
Using a secure messenger, you can be sure of the safety of your data and the privacy of your communication.
Unlike other programs, a secure messenger may have the following features (not all at once, but some of them):
- multi-factor authentication;
- self-destruction of messages;
- screenshot control;
- data storage on secure servers;
- open source code;
- no metadata collection.
Corporate companies, individuals, even government agencies are increasingly turning to secure messengers for communication in search of a reliable solution for their communications.
The most secure instant messengers for correspondence in 2025
We have compiled a list of the most secure messengers so that you can choose the one that suits your needs.
1. eXpress
eXpress stands out from other messengers because has a FSTEC RF certificate, which confirms its reliability and compliance with high security standards.
One of the main advantages of eXpress is its on-premise servers, which are provided to corporate customers. This means that data and files are stored on the organization's internal servers, providing even greater control and information security.
Authentication via 3 independent channels – This is an additional layer of security that ensures that only properly authorized users have access to the messenger. The cryptocontainer and 2 layers of elliptic curve data encryption (E2EE) provide reliable encryption and protection of transmitted information.
One of the unique features of eXpress is the ability to configure file and data access policies according to specified parameters. For example, you can restrict access to certain files or prohibit their transfer and saving to external media.
In addition, eXpress offers an enhanced privacy mode, which includes an automatic deletion timer.
2. Signal
This is an application that offers powerful secure encryption and is open source, which means that security experts can carefully study it and verify its reliability.
One of the key features of Signal is its end-to-end secure encryption. An important feature of Signal is its Screen Security. It prevents you from taking screenshots of messages to prevent unauthorized distribution of your private information. This way, your conversations remain only between you and your interlocutor. In addition, you can use the self-destructing message feature.
However, Signal not only provides high security, but also pays attention to privacy. It does not track your location or collect data.
3. Wickr Me
This app was positioned as a tool for anyone who values the security of their private conversations.
What makes Wickr Me special? First, the app actively cares about your privacy by removing metadata such as geolocation and message time.
Unlike many other messengers, Wickr Me does not require a phone number or email address to create an account. This gives you greater freedom and anonymity when using the app.
While Wickr Me will no longer be available to the general public as a consumer product, its evolution as a secure service for businesses and governments opens up new possibilities. It could be a great choice for organizations and government agencies that value the security and privacy of their communications.
4. Wire
Wire is a messenger that leaves no chance for violators of your privacy.
It uses strong encryption algorithms, is open source, and even offers a self-destruct function for messages. But that’s not all – Wire undergoes ongoing security audits to ensure that your data remains secure.
One of the benefits of Wire is its ability to integrate with other popular apps and services. You can easily integrate it with Dropbox, Trello, GitHub, and other platforms, making it easier to communicate and collaborate with your team.
Wire also offers powerful collaboration capabilities. You can share documents, screen share, and message in groups.
5. Threema
This messenger opens up a huge world of communication for you. Here you can exchange text messages, voice and video recordings, as well as transfer large files. But that's not all! Threema offers the ability to create polls and newsletters so that you can easily and conveniently interact with your contacts.
One of the main advantages of Threema is its strict compliance with data protection regulations and standards. All information related to users is stored locally on their own devices. Threema does not record user data and is GDPR compliant, ensuring you have maximum privacy.
However, it should be noted that Threema does not offer two-factor authentication and is a paid app.
The unique feature of Threema is the ability to create unique identifiers that are not linked to your personal information. This makes tracking and identifying the sender of messages extremely difficult, ensuring your anonymity and security.
6. Element
Element is not just a messenger, but an entire app that combines security and collaboration in one place. Here you will find reliable messaging and functionality for effective collaboration. And the best thing is that Element is open source.
However, like any product, Element has its drawbacks. One of them is a slightly outdated interface. But don’t let it scare you off, because behind this unassuming shell lies a powerful tool for protecting your privacy.
Element’s advantages include the use of the Matrix protocol combined with end-to-end encryption. The Matrix protocol is designed specifically to ensure the security and privacy of users, adding another layer of protection to your correspondence.
However, security is not all that Element offers. It is also known for its flexibility and customizability. You can easily customize the application with various themes, plugins, and integrations to make it as convenient as possible and suit your needs.
Which messenger is the safest and most secure? Choice for company data protection
When it comes to protecting corporate data, using public messengers is not the best solution. Many of them, with the exception of Russian solution eXpress, are developed by foreign companies. It is important to understand that the data is stored on servers abroad, which may be unacceptable for official corporate communication.
Public messengers may seem convenient, but they often leak important company and customer data. Employees can accidentally send data to the wrong recipient, make it available to the entire network, or even neglect the security of their device. The result can be a data leak, serious reputational losses for the organization, and a decrease in trust from users. That is why corporations should use not just secure messengers, but specialized corporate messengers with the ability to store data on the company's own servers.
Using such messengers will help comply with data protection rules and prevent possible legal and financial consequences associated with information leakage. Secure corporate messengers ensure that confidential information remains just that. This is especially important for companies that work with customer data, intellectual property, and other business-critical information. In addition, the use of foreign messengers is becoming impossible at the legislative level for a number of Russian companies, financial organizations and government agencies (see Federal Law No. 584-FZ "On Amendments to the Federal Law "On Information, Information Technologies and Information Protection").
Transfer data with confidence - choose a secure messenger that will ensure the security of corporate data, the preservation of important information within the company and compliance with legal requirements. Data protection is an important aspect of successful business interaction, and choosing the right corporate messenger will play a key role in ensuring the security of your company.
