| 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. | Autonomous pentesting platform that runs unlimited self-directed internal, external, cloud, Kubernetes and AD pentests, plans attack paths, guides remediation and re-tests to verify fixes. |

- AISLE (autonomous vulnerability discovery, triage and verified-fix agents) — Prague-headquartered AI code-security platform in which thousands of agents analyse a codebase in parallel for exploitable vulnerabilities, fix agents write patches, and agentic verification builds the repo and runs tests before opening a pull request for human merge. October 2026 added agent-driven proof of exploitability against running web apps and APIs. Cohere signed a letter of intent to acquire AISLE on Oct 15, 2026.
- 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
- 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.
- Rescana autonomous TPRM agents (Discovery & Classification, Risk Assessment, Communication & Remediation and Manager agents) — A third-party risk platform run by a coordinated team of AI agents. They discover and classify vendors from identity, procurement and IT systems, collect and analyse vendor documentation and questionnaires against external attack-surface intelligence, chase vendors for missing evidence and remediation, and orchestrate approvals with humans in control.
- 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
