The recent political scandal triggered by top U.S. officials accidentally exposing sensitive group chats on Signal has sparked widespread attention, not just on their digital hygiene, but on the app itself. Despite this amateur blunder, cybersecurity experts still agree: Signal remains one of the most secure messaging apps available to the public. But that doesn’t mean it’s suited for state secrets.
Steven Meyer, Co-CEO and Co-Founder of ZENDATA Cybersecurity, weighed in bluntly: “At the military and government level, there are very secure and strictly controlled tools for classified communications. They’re not user-friendly. So, whenever possible, people default to easier options. In that field, Signal is by far the best.”
The app’s end-to-end encryption protocol, open-source foundation, and ad-free model make it a privacy darling, far ahead of WhatsApp or Telegram. Even governments demanding backdoors haven’t succeeded in cracking their core protections. As Steven puts it, “To my knowledge, Signal’s protocol has never been broken. But I also know some governments are trying. No security is forever.”
Yet, Signal isn’t invincible. If a phone is compromised, physically or remotely, all bets are off. Plus, as this scandal proves, no app can fix poor user behavior. Letting an unknown journalist into a high-level political group chat is less a technical breach and more a digital facepalm.
In Switzerland, Steven notes that Threema is the local go-to for governmental but non-critical communications. For truly sensitive topics, the Swiss, like others, resort to tools far beyond the reach of the public.
Expert Analysis:
This incident isn’t about Signal’s flaws. It’s about human ones. Even the most secure app can’t compensate for sloppy habits. And when leaders confuse usability with suitability, they trade classified integrity for convenience.
Signal did its job. The officials didn’t.
