#SecureCommunications: Is Strong Encryption Alone Enough? | SSH

In the age of encrypted everything, one thing is clear: encryption alone is no longer enough.

Recent high-profile incidents involving Signal—a platform widely known for its end-to-end encryption—have highlighted the real-world risks that remain even in so-called “secure” environments. 

 

Signal in the headlines: Two lessons in risk 

Recently, The Guardian reported a startling security lapse involving the Signal app. A U.S. national security official accidentally added a journalist to a private Signal group chat discussing classified military operations.  

The journalist, who had been interviewing a different participant, was unknowingly granted access to a conversation about potential military strikes in Yemen. While the group was deleted minutes later, the leak had already occurred—demonstrating how easily sensitive content can be exposed through simple user error. 

Around the same time, BleepingComputer reported on Russian state-sponsored phishing campaigns exploiting Signal’s “Linked Devices” feature. Attackers sent malicious emails designed to trick users into unknowingly linking their Signal accounts to rogue devices.  

Once linked, attackers had full access to the target’s private messages and contacts—without ever needing to break Signal’s encryption. Both incidents highlight a critical point: encryption isn’t a silver bullet. 

Human error and operational blind spots  

The core issue in both cases wasn’t encryption failure—it was a lack of control, visibility, and verification. When unauthorized users can access private channels because of mistaken invites or phishing links, even the most secure platform becomes vulnerable. 

What’s missing is operational trust—a layered approach that combines cryptographic protection with access governance, device-level control, and real-time monitoring. 

A better way: Operational-grade messaging security with SalaX Secure Messaging 

In a world where human error, sophisticated phishing, and zero-day vulnerabilities are daily realities, relying only on encryption is like locking your front door but leaving the windows wide open. 

At SSH Communications Security, we’ve long believed that modern messaging requires more than strong end-to-end encryption. It demands Zero Trust architecture strong access verification by design.  

That’s why we developed SalaX Secure Messaging, a secure communications solution tailored for the realities of mission-critical operations. 

SalaX Secure Messaging solution is developed by SSH, using both the Element communications platform and the decentralized Matrix open standard for secure and interoperable communications. We are a Silver member of the Matrix organization.  

It is the same technology stack as used by the French government, the German Armed Forces (Bundeswehr), NATO ACT (experimental project), Sweden’s Försäkringskassan, United Nations International Computing Centre and the US Department of Defense. Element was also cited as a Strong Performer in the Forrester Wave for Secure Communications (Q3 2024).  

Don’t leave your business-sensitive chats, rooms, calls or video conferences to chance.
