As governments and corporations escalate digital surveillance, encrypted messaging apps are becoming vital tools for reclaiming communication privacy.

In 2025, data breaches compromise billions of records annually, while state-driven surveillance intensifies. The UK, France, and Sweden have pushed measures threatening end-to-end encryption (E2EE), with the EU’s Chat Control proposals risking mandatory message scanning. In the US, the STOP CSAM Act of 2025 seeks to weaken E2EE for content monitoring, mirroring global trends where at least 17 countries have restricted encryption under safety pretexts. These policies, often justified as protecting public interest, fuel the need for secure communication platforms.

Signal leads with its open-source protocol, offering E2EE for texts, calls, and video chats. Its strengths include a user-friendly interface, no ads, minimal data collection (phone numbers for verification), and features like disappearing messages and sealed senders to obscure metadata. Drawbacks include centralised servers, vulnerable to legal demands, and occasional multi-device sync issues. As a nonprofit, Signal aligns with privacy-first principles, collecting far less data than mainstream alternatives like WhatsApp, which risks metadata exposure due to Meta’s ownership.

Session pushes decentralization further, using onion routing on the Oxen blockchain for anonymous communication without phone numbers or central servers. Its advantages are true anonymity, tamper-resistant records, and auditable code. However, its smaller user base can cause latency, community channels lack E2EE unless self-hosted, and the interface is less intuitive. Session suits those prioritizing metadata protection over convenience.

Avoid apps like Telegram, where E2EE is limited to secret chats, or WhatsApp, where metadata vulnerabilities persist. Both lag Signal and Session in privacy guarantees. The rise of these apps reflects a broader resistance against surveillance creep, empowering users to control their digital interactions.

Setting up is straightforward: For Signal, download from signal.org, verify with a phone number (or use usernames), enable PIN locks, and activate disappearing messages for added security. For Session, install from getsession.org, generate an anonymous ID, and connect via onion-routed groups. Always verify contacts’ safety numbers to prevent man-in-the-middle attacks.

As encryption faces global threats, amplified by debates over AI integration and backdoor mandates, these apps embody an ethos of defiance. They offer practical ways to shield communications from prying eyes, whether for whistleblowers, activists, or everyday users. Adopting E2EE isn’t just a technical choice; it’s a stand for sovereignty in a surveillance state. Stay encrypted, stay free.
