| Summary | Autonomous penetration testing built into the Dublin-based Edgescan platform, launched October 7, 2026. A team of narrow AI agents plans, adapts, chains vulnerabilities and validates real impact on web applications, using Edgescan's existing asset context and findings, while a deterministic 'Harness' enforces scope, permissions, approvals and allowed actions. Findings land alongside Edgescan's DAST, PTaaS and ASM results. | Security Copilot agent in Microsoft Defender that autonomously triages user-reported phishing, resolves false positives and explains each verdict. |

- Blackpoint AI SOC Agent for ITDR (autonomous identity threat containment for Microsoft 365 and Google Workspace) — AI SOC agent inside Blackpoint's managed ITDR service that autonomously contains high-confidence credential attacks on Microsoft 365 and Google Workspace accounts: it suspends the account, forces a password reset, ends active sessions and logs its reasoning, and escalates anything below its confidence threshold to a human SOC analyst. Generally available since July 8, 2026. · Blackpoint AI SOC Agent for ITDR (autonomous identity threat containment for Microsoft 365 and Google Workspace) pair comparison
- Bricklayer AI security agents (agentic platform for the AI security workforce) — Agentic cybersecurity platform that deploys, coordinates and governs teams of role-based and tool-specialist AI agents to triage alerts, investigate incidents, run threat-intelligence and threat-hunting work and track vulnerability remediation inside analyst-approved procedures, with every agent action auditable. · Bricklayer AI security agents (agentic platform for the AI security workforce) pair comparison
- Check Point Agentic Exposure Validation (AEV, AI agents that prove external exploitability) — Part of Check Point Exposure Management, launched May 28, 2026. AI agents reason like attackers across an organisation's external attack surface, correlating exposures, leaked credentials, CVE and live exploit research with existing protection coverage, then safely prove, pivot on, or discard each finding, so teams get evidence of what is actually exploitable. · Check Point Agentic Exposure Validation (AEV, AI agents that prove external exploitability) pair comparison
- Command Zero Agent Zero (autonomous security analyst) — Autonomous and AI-assisted SOC investigation platform from Austin, Texas. Its LLM agent, Agent Zero, investigates alerts end to end across identity, endpoint, cloud, email and SaaS, auto-closes routine cases with documented reasoning, and escalates the rest with a replayable chain of evidence for analysts to confirm or override. · Command Zero Agent Zero (autonomous security analyst) pair comparison
- depthfirst autonomous security agents (code, supply chain, secrets and agentic pentesting) — San Francisco application-security platform whose autonomous AI agents trace business logic and data flows to find exploitable code vulnerabilities, check dependency reachability and secrets, review pull requests with proposed fixes, and run agentic pentests against running applications, re-running each attack after a fix merges to confirm it is closed.
- Nullify autonomous product-security agents (find-to-fix with merge-ready PRs and AI Pentest Agent) — Australian 'autonomous system of agents' for product security that covers code, secrets, API pentesting and exploit validation. It proves findings with reproducible evidence, scores them against the customer's assets, writes merge-ready fix PRs routed to code owners, and runs remediation campaigns through Jira and Slack until merge, with the customer keeping final merge approval.
- Ontinue ION MXDR autonomous investigations (agentic AI SOC for Microsoft Defender and Sentinel) — Zurich-headquartered managed detection and response provider for Microsoft Defender and Sentinel whose ION MXDR service uses a team of AI agents to run autonomous Tier 2-level incident investigations (aggregate telemetry, form and test hypotheses) before handing a step-by-step summary to an Ontinue Cyber Defender. · Ontinue ION MXDR autonomous investigations (agentic AI SOC for Microsoft Defender and Sentinel) pair comparison
- Ridge Security RidgeGen (agentic AI red teaming) and RidgeBot — Offensive-security vendor from Milpitas, California. Its on-premises, model-agnostic RidgeGen agent does agentic AI red teaming: it reasons through multi-step attack chains to find business-logic and non-CVE risks, verifies every finding with reproducible exploit evidence, gives fix guidance and re-runs to confirm fixes. It sits alongside RidgeBot automated pentesting. · Ridge Security RidgeGen (agentic AI red teaming) and RidgeBot pair comparison
