Encryption is not enough
Modern security conversations still tend to begin with encryption.
That is understandable. Sensitive data has to be protected from interception, manipulation, and unauthorized access. In defense, intelligence, critical infrastructure, and other high-consequence environments, strong cryptography is table stakes.
Encryption alone does not make a system resilient.
A message can be unreadable and still be visible. Its timing, route, volume, destination, and relationship to other activity may reveal that it matters. In contested or monitored environments, that may be enough.
