What Does MITRE ATT&CK Coverage Really Mean?

Security teams often see vendors claim full MITRE ATT&CK coverage, but the reality behind those numbers is rarely clear. This AMA session breaks down what ATT&CK coverage actually means and why percentage based claims are often misleading when comparing security tools or services.

Led by former MITRE experts, the discussion examines how ATT&CK tactics and techniques are tested across different use cases, why coverage depth matters, and what responsible exclusions look like in real programs. The session focuses on helping buyers and practitioners evaluate vendor claims more critically and use the ATT&CK framework to support smarter validation and purchasing decisions through real world examples and audience driven questions.
