In both assessments, the red team achieved full compromise at the domain level. However, the key divergence lay in detection: one organization identified and responded to the intrusion activity, while the other detected nothing throughout the entire operation. CISA’s report highlights how the same attack methods can yield vastly different results depending on an organization's monitoring capabilities and incident response maturity.

• Full domain compromise was achieved in both assessments.
• One organization remained entirely unaware of the red team activity.
• The other organization successfully detected and responded to the intrusion attempts.
• CISA emphasized that the tradecraft used was similar, pointing to defensive gaps rather than advanced attacker techniques as the deciding factor.

The report underscores a persistent issue in critical infrastructure: even well-resourced entities may lack the visibility needed to catch determined adversaries. CISA’s findings serve as a reminder that detection and response capabilities are just as vital as preventive controls.

Does your organization have a tested incident response plan in place, and how confident are you that you would detect a similar domain-level compromise?
