RunSybil Sybil (AI offensive security / autonomous pentesting)

What it does

RunSybil, a US company with hubs in San Francisco and New York City, sells Sybil, an AI-powered offensive security platform. Its pages say Sybil runs autonomous penetration-testing engagements (black box or white box, where the agents are given source access) and tests live systems with AI agents that learn about the target. It explores authentication boundaries, finds forgotten endpoints and chains weaknesses such as broken authorisation, cross-tenant access and privilege escalation into exploitable paths. Every finding is independently reproduced before delivery and ships with a CWE ID and remediation guidance precise enough to hand to an autonomous coding assistant, with retesting available. Sybil keeps a model of the application and infrastructure and re-evaluates what changed on every deployment, and RunSybil positions it for continuous testing, adversarial exposure validation and SOC 2 penetration-testing reports.

Alternatives

• 
  7AI agentic security platform — Boston-based agentic security platform where swarms of specialised AI agents categorise, investigate and reach a determination on every alert, escalating only what needs a person, with optional managed service (PLAID ELITE).
• 
  Abnormal AI Security Mailbox (Abnormal AI for Government) — Autonomous agent for email security operations that triages user-reported emails, removes related malicious campaign messages across the organisation and replies to reporters; included in Abnormal AI for Government, which is FedRAMP and GovRAMP Moderate authorized.
• 
  Adaptive Security Agentic Email Security and Phish Triage — API-based 'agentic email security' that re-analyses inbound mail after native filtering with ML and LLM reasoning and removes confirmed threats across every inbox automatically (configurable human-in-the-loop thresholds). AI Phish Triage classifies employee-reported emails and acts on them, feeding Adaptive's simulations and awareness training.
• 
  Aikido Attack AI Pentesting — Belgian autonomous AI pentest: many agents map the app, test attack paths and re-exploit each finding to confirm it, with a same-day audit-grade report.
• 
  AIpentix (agentic continuous security testing and agentic red teaming, by Swipergy) — German continuous security-testing platform with an AI agent that signs in to the customer's application on its own, chooses follow-up checks and documents attack paths, with every tool run evidenced. Findings are grouped into remediation actions with owners, deadlines and Jira sync, and retests confirm fixes. Agentic red-team campaigns (recon, access, lateral and report agents led by human red teamers) are also offered for TIBER-EU and DORA TLPT style testing.
• A
  Andesite Human-AI SOC (Azimuth for Government) — Agentic SOC platform with configurable agents for alert triage, enrichment, investigation and remediation under analyst oversight; its government offering is FedRAMP High authorized.
