Rethinking Secure Comms: Are Encrypted Platforms Still Enough?

A leak of information on American military operations caused a major political incident in March 2025. The Security Think Tank considers what can CISOs can learn from this potentially fatal error.
In today's constantly changing cyber landscape, answering the question 'what does best practice now look like?' is far from simple.
