Autonomous Defense & Response
Knowing about a threat is not enough. Vanguard acts on it — at machine speed, across every surface of your enterprise, within governance boundaries your team defines. It determines the right action, executes it, and validates it worked. All within seconds.
Vanguard™ Response Surfaces
Vanguard runs a continuous autonomous response loop — always evaluating threat context, always ready to act, always validating that actions achieved their intended outcome.
Vanguard receives fully investigated, contextual threat intelligence from Overwatch AI — not raw alerts. It knows what happened, which systems are affected, what the attacker’s likely next move is, and what Atlas says about the blast radius of the current exposure.
Vanguard’s decision engine evaluates the optimal response based on threat severity, business criticality of affected assets, current trust levels, active policy rules, and attack progression stage — selecting the least disruptive containment action that effectively neutralizes the threat.
Before acting, Vanguard checks every action against your enterprise governance model. Some actions execute autonomously. Others route to an analyst for approval. High-impact actions require executive sign-off. Emergency override controls are always available. Every path is pre-defined by your team — not us.
Vanguard executes containment actions across identity systems (session termination, credential revocation), endpoints (isolation, process kill), SaaS platforms (account suspension, OAuth revocation), cloud environments (workload quarantine, IAM restriction), and AI agents (suspension, tool access restriction) — simultaneously and at machine speed.
Vanguard doesn’t just act and move on. It continuously verifies that containment succeeded — checking that attacker access is gone, that risk has been removed, and that trust has been re-established. If residual risk remains, it automatically escalates or takes additional action.
Continuously evaluates threat context, business criticality, trust levels, and policy constraints to select the optimal defensive action — without requiring human judgment for every decision.
Configurable governance tiers let your team decide exactly which actions are autonomous, which require analyst approval, and which require executive sign-off — with full separation of duties support.
From threat confirmation to containment action in under 60 seconds — across endpoint isolation, session termination, credential revocation, and agent suspension simultaneously.
Automatically removes excessive permissions, revokes privileged access, enforces step-up authentication, and restricts lateral movement during active incidents — reducing attack surface in real time.
Every response decision incorporates current trust signals from TrustAnchor — identity trust, device trust, session trust, application trust, and agent trust scores — ensuring responses are proportionate and contextual.
Continuously verifies containment success, checks for residual risk, confirms attacker access removal, and provides evidence that trust has been re-established before clearing an incident.
When Overwatch AI detected a credential stuffing attack targeting high-privilege accounts, Vanguard automatically terminated 340 active sessions, revoked OAuth tokens for 12 connected SaaS applications, and enforced MFA re-enrollment — all within 47 seconds of threat confirmation.
Vanguard detected and contained ransomware lateral movement across 14 endpoints before encryption began — automatically isolating affected systems, revoking the compromised service account, and preventing spread to adjacent network segments while keeping critical OT systems operational.
When Overwatch AI identified an insider threat exfiltration attempt, Vanguard routed the response through the executive approval workflow (per policy for HR-related incidents), received approval in 3 minutes, and immediately suspended the account and revoked all active sessions across 8 SaaS platforms.
When AgentShield detected a prompt injection attack successfully manipulating an internal AI agent, Vanguard automatically suspended the agent, revoked its API credentials, blocked its workflow execution, and isolated its MCP server connections — all before the manipulated action could execute.
Vanguard uses Atlas for context, Overwatch AI for investigation results, TrustAnchor for trust signals, and AgentShield for AI agent containment — making every response smarter than any standalone tool.
Vanguard executes machine-speed defensive actions across your entire enterprise — within your governance boundaries, with full audit trails.
