What happened
Zero Networks announced (published Aug 3, 2026, Black Hat USA) Least Agency Enforcement, implementing OWASP's emerging Least Agency principle via identity-based microsegmentation, automated policy enforcement and just-in-time MFA to restrict what AI agents can reach and when human approval is required.
Why it matters
Moves AI agent governance to the network/identity layer rather than the application layer, directly addressing the 'agent reach if manipulated' risk highlighted by recent MCP and agent-related CVEs.
Applicability
Security architecture teams building zero-trust controls around autonomous agents; available now.
