ColdRecon assessment

Could a positive-security control have prevented this?

Verdict · would prevent · opinion

A positive-security model that only allows known-good executables and scripts would likely have blocked the ransomware from executing, as it would be unrecognized and unauthorized.

Our assessments are opinion, grounded in the cited public facts. Read them critically.
