Agentic Index
RunSybil vs XBOW (2026)
RunSybil last verified ·XBOW last verified
RunSybil and XBOW both run autonomous offensive testing against live applications and validate exploits before reporting. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
RunSybil's agent system, Sybil, tests on every pull request, on a cadence or on demand, chains findings into exploit paths and pushes them to GitHub and Linear, with a public API and an MCP server. It sells through sales after a demo. XBOW's coordinator directs short lived attack agents against web applications and APIs, with independent validators, scope and rate controls and every agent action logged. On AWS Marketplace, 12 months of XBOW attack credits cost $50,000, used up as tests run. XBOW offers data residency in the US, EU or Singapore with SSO and user roles, while RunSybil keeps one picture of the estate that every engagement updates. Choose RunSybil for testing tied to every pull request. Choose XBOW for regional hosting, scope controls and a public price.
On the Agentic Index AI SOC ranking, neither RunSybil nor XBOW clears the bar, which asks for all five investigation loop capabilities documented in full. Neither documents human oversight and guardrails in full. 25 of the 86 vendors in the lane clear it. See the AI SOC ranking

RunSybilIntegrations & Tool Calling Sybil connects to GitHub or GitLab to test on every pull request or push. It pushes findings to GitHub and Linear as tickets, mapped one to one and updated incrementally, and Jira support is coming. The agents act on the customer's live applications and infrastructure during testing. Sourcerunsybil.com/continuous-testing-for-application-securityread 2026-09-28 |

RunSybilWorkflow Orchestration A hierarchy of specialized agents tests hypotheses across the application, each owning a domain such as authentication, business logic or injection. Findings are chained into exploit paths, a dedicated false positive triage agent screens them, and a validator agent reruns attacks after remediation. Sourcerunsybil.com/platformread 2026-09-28 |
||
|
XBOWWorkflow Orchestration A coordinator decides what to test, where and in what order and directs short-lived attack agents across the fleet, with independent validators confirming exploitability. Agents run concurrently by default, or one at a time in sequential mode. The agents are all XBOW's own. Sourcexbow.com/platformread 2026-09-28 |

RunSybilTriggers & Channel Coverage Sybil tests on every pull request or push, reading the diff and testing what changed. It also runs on a recurring daily, weekly or monthly cadence the customer defines, and manual runs and API triggered tests are available too.

XBOWTriggers & Channel Coverage Customers can trigger a pentest on merge or pre-deploy through the API from their own CI or scheduler. Console runs start from a Start assessment button, and testing windows pause and resume a running assessment automatically. The trigger is wired through the customer's pipeline.

Knowledge Grounding & RAG Ability to ground agent behavior in company data through document ingestion, retrieval, external knowledge APIs, semantic search, or RAG layers. |
||
|
RunSybilKnowledge Grounding & RAG Credentials, OpenAPI specs and source code are optional inputs to a black box test, and pull request runs read the diff to test what changed. There is no maintained retrieval structure over the customer's own knowledge. Notion, Confluence and Google Docs integrations are under evaluation. Sourcerunsybil.com/autonomous-pentestingread 2026-09-28 |

|
XBOWKnowledge Grounding & RAG Source code, documentation, API specifications and prior reports go into a file library shared by the organization and are chosen as context for each assessment, alongside a live map of the attack surface. There is no index or retrieval layer over that library, so context is assembled for each run. Sourcedocs.xbow.com/console/how-to/provide-target-contextread 2026-09-28 |

|
XBOWMemory & State Persistence Agents are short-lived and retired after each mission. The attack surface map and context library feed each assessment, and context reused on a retest is configuration, not agent memory. Sourcexbow.com/platformread 2026-09-28 |

Human Oversight & Guardrails Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls. |
||
|
RunSybilHuman Oversight & Guardrails The customer defines what the program protects and how success is measured, and rules of engagement are confirmed before an engagement begins. There is no approval step before an exploit or other action goes through. Sourcerunsybil.com/agentic-adversarial-exposure-validation-aevread 2026-09-28 |
||
|
XBOWHuman Oversight & Guardrails The customer sets scope, a limit on requests per second, testing windows (business hours, off hours or custom) and sequential mode, and can pause an assessment. In Autonomous Exposure Management the customer approves the target list before any testing begins, XBOW sorts what it finds into what it may attack and what it may only visit, agents prove exploits benignly (a SQL injection gets a one time sleep, not a dropped table), and assessments pause when a target becomes unstable. There is no approve or confirm step before an individual exploit attempt runs. Sourcedocs.xbow.com (execution options) and xbow.com/blog/introducing-autonomous-exposure-managementread 2026-10-24 |

XBOWDeployment & Data Residency Each organization lives in one region, with findings, assessment results, asset inventory, credentials, uploaded specs and source code, audit logs and user identity stored there. Regions run in the US, the EU and Singapore, and since October 2026 in Australia, Canada and Japan in private preview. Each is a full deployment on AWS with its own console at console.xbow.com or its .eu, .sg, .au, .ca or .jp form. Billing, support tickets and telemetry stay global, and assessments use approved global model providers, so model processing may happen outside the region. Delivery is SaaS, and the cloud marketplaces are purchase channels. Sourcexbow.com/blog/xbow-data-residency-now-available-in-australia-canada-and-japanread 2026-10-24 |

RunSybilPrebuilt Agents, Templates & Packs Sybil's named agents work inside the product, and the customer does not choose among them. They are the Discovery Agent, the Attack Agent, domain agents for authentication, business logic and injection, a false positive triage agent and a validator agent. Autonomous pentesting, adversarial exposure validation, continuous testing and SOC 2 penetration testing are uses of one product. Tests can be cloned, but there is no template library.

RunSybilAPIs, SDKs & MCP Extensibility RunSybil publishes a public API, authorized with org scoped API keys, that creates and configures applications, scope, accounts and source code, triggers tests, checks status, pulls reports, queries findings and starts retests. An MCP server supports most API workflows except launching tests, for assistants such as Codex, Claude Code and Cursor. RunSybil publishes what the API covers and how it authenticates, but it has no public API reference, and the MCP server's endpoint and tool list are not public.

RunSybilTesting, Debugging & Optimization Sybil does not test, evaluate or red team the customer's AI applications or agents. Its validator agent reruns attacks after remediation, and retests complete in under an hour, but those retests check the customer's applications and infrastructure.
