In an era where digital communication dominates our interactions, the need for secure messaging has never been more pressing. The rise of online conversations has led to an increasing awareness of the vulnerabilities associated with traditional messaging platforms. As we navigate this landscape, the importance of encrypted messaging apps becomes paramount for safeguarding our private communications.
Why you need to use secure messaging
When engaging in online conversations, many individuals operate under the assumption that their exchanges are private. However, various entities, ranging from corporations to government agencies, actively seek to monitor these communications. The threats are multifaceted:
- Corporations aim to harvest your messages to refine their advertising strategies or to sell your data to the highest bidder.
- Hackers exploit personal information to commit identity theft, infiltrate bank accounts, or even engage in blackmail.
- Government bodies often seek to surveil citizens in the name of national security, potentially infringing on personal privacy.
Without a secure messaging service, your communications are vulnerable to interception by any of these groups. The shift to remote work due to recent global events has further exacerbated these risks, as home networks typically lack the robust security measures found in corporate environments.
In response to these challenges, a surge of messaging services touting privacy and security has emerged. However, not all of these platforms offer the same level of protection. Some may only encrypt messages during transmission, leaving them accessible to the service provider, while others may have questionable ownership or a history of security breaches.
To enhance your security, it is advisable to pair any messaging app with a reliable VPN, such as NordVPN, which has successfully undergone independent privacy and security audits.
Best encrypted messaging apps
Through extensive testing, we have identified several messaging services that stand out for their commitment to secure communication.
Signal – The most secure messaging app
Signal has gained significant traction, particularly following privacy concerns surrounding WhatsApp. This app is widely regarded as the gold standard for secure messaging, thanks to its end-to-end encryption and open-source foundation. The Signal Protocol, which underpins its encryption, is so robust that it has been adopted by other major platforms.
Signal allows for self-destructing messages and has consistently passed third-party security audits, earning endorsements from privacy advocates like Bruce Schneier and Edward Snowden. However, it does require a phone number for registration, which may deter some users concerned about privacy.
+ Pros
- End-to-end (E2E) encryption
- Open-source with transparency reports
- Self-destructing messages
- Minimal data logging
- Free of charge
– Cons
- Requires a phone number for registration
- Lacks Two-Factor Authentication (2FA)

Threema – Anonymous messaging app with no data collection
Threema, while lesser-known, offers a compelling option for secure communication. With around 5 million users, it allows for completely anonymous messaging without the need for a phone number or email address. Each user is identified by a randomly generated ID, ensuring that personal data remains private.
Threema also provides a business version and supports various features, including file sharing and group messaging. Although it lacks a free version, its focus on privacy and security makes it a strong contender.
+ Pros
- End-to-end (E2E) encryption
- Anonymous messaging

Telegram – Secure messaging app with 500+ million users
Telegram has seen substantial growth, particularly in light of privacy concerns surrounding other platforms. With over 500 million active users, it offers a balance between security and accessibility. However, it is important to note that not all communications on Telegram are end-to-end encrypted by default; only voice calls and Secret Chats offer this level of protection.
While Telegram boasts a rich feature set, its logging of user data and the questionable security of its encryption protocol, MTProto, may raise concerns for some users. Utilizing a VPN can help mitigate these issues.
+ Pros
- End-to-end (E2E) encryption for specific features
- Self-destructing messages
- Supports Two-Step Verification
– Cons
- Requires a phone number for registration
- Not all communications are E2E encrypted
- Logs user data

Messaging apps and practices to avoid
While exploring secure messaging options, it is equally important to recognize platforms that may compromise your privacy.
1. WhatsApp (owned by Facebook)
Despite its encryption, WhatsApp is owned by Facebook, which raises significant privacy concerns. The platform collects extensive metadata, which can be exploited by both the parent company and government agencies.
2. Keybase (now owned by Zoom)
Keybase’s acquisition by Zoom, a company with a controversial privacy track record, has led to skepticism regarding its security and user privacy.
3. Regular (unencrypted) SMS text messages
Standard SMS messages lack encryption and can be easily intercepted, making them a poor choice for private communications.
Characteristics to look for when selecting an encrypted messaging app
When evaluating secure messaging apps, consider the following essential characteristics:
- End-to-end (E2E) encryption
- Third-party testing and reviews
- Open-source code
- Self-destructing messages
- Limited user data collection
- Anonymous signup options
