What happened
Quest Software announced (Sept 16, 2026) a major expansion of its Security Management Platform including Identity Insights (built on its Anetac acquisition) and Agentic AI Defense, which autonomously isolates a compromised human/non-human/agentic identity mid-attack across the NIST CSF lifecycle.
Why it matters
Addresses agentic-identity blast-radius containment (auto-isolation during an active attack) rather than just detection/reporting, a gap flagged across multiple Sept 2026 agent-hijacking incidents.
Applicability
Enterprises with Active Directory/Entra ID and growing non-human/agentic identity footprints should evaluate for incident containment and recovery.
