CISA Red Team Finds One Org Compromised, Another Detected Attack

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has revealed the starkly different outcomes of two simultaneous red team assessments against critical infrastructure organizations, finding that one was completely compromised while the other quickly detected and contained the simulated attack. The findings, published in an advisory on August 25, 2026, highlight that effective defense depends more on trained personnel and proper processes than on the security tools themselves.
