XBOW
Autonomous offensive security platform where a coordinator directs short lived attack agents that chain and validate exploits against web applications and APIs, now across a whole external application estate with Autonomous Exposure Management. Scope, rate and testing window controls, every agent action logged, a versioned REST API and webhooks for CI triggers, Jira and Microsoft Sentinel integrations, and regions in the US, EU and Singapore, with Australia, Canada and Japan in preview. Usage based credits, with a $50,000 a year package on AWS Marketplace.
XBOW is an autonomous offensive security platform that runs penetration tests against a customer's web applications and APIs. A coordinator decides what to test, where and in what order and directs short lived attack agents, which are retired after each mission, while independent validators confirm exploitability before a finding is reported. The platform builds a live map of the attack surface (applications, endpoints, parameters and authentication flows) and draws on context the customer uploads to an organization wide file library, such as source code, documentation, API specifications and earlier reports.
Autonomous Exposure Management, launched in September 2026, extends this to a company's whole external application estate. XBOW discovers what is exposed, the customer approves the target list before testing begins, and thousands of agents test from the outside in parallel, proving each exploit benignly and pausing when a target becomes unstable. Customers set scope, a limit on requests per second, testing windows and sequential or concurrent execution, and every action the agents take is logged and reviewable.
Findings arrive with proof of concept exploits and remediation guidance, can be retested, and flow to Jira, Microsoft Sentinel and Security Copilot. A versioned REST API with webhooks lets teams trigger a pentest on merge or before a deploy from their own CI. XBOW is delivered as SaaS from regions in the US, the EU and Singapore, with Australia, Canada and Japan in private preview since October 2026, offers single sign on and user roles on the Enterprise tier, and is sold on usage based credits, including through the AWS, Google Cloud, Oracle and Microsoft marketplaces.

Integrations
The Jira integration creates work items from findings; the Microsoft integration deploys a Sentinel connector and lets Security Copilot query findings and run assessments (both in public preview). A versioned REST API with bearer-token auth creates assets, triggers assessments and retrieves findings, and signed webhooks route assessment and finding events to other systems, so pentests can run on merge or before a deploy from the customer's CI. Context such as source code, documentation and API specifications is uploaded to a shared file library.
In practice
A team triggers an XBOW pentest from its CI pipeline on every merge, and the coordinator directs attack agents across the application while validators confirm each finding before it becomes a Jira work item.
A security team caps requests per second, limits testing to off hours and pauses an assessment when production load rises, then reviews the log of every action the agents took.
A European company runs assessments from the EU console so its data stays in the EU region, with single sign-on and an IP allowlist for its team.

XBOW integrates with Jira (work items from findings), a Microsoft Sentinel connector and Security Copilot (query findings, run assessments), sends webhooks for assessment and finding events, and gives the agents an offensive toolkit they chain during testing.

| Workflow Orchestration | Full |
|
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 |

| Knowledge Grounding & RAG | Partial |
|
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 |

| Human Oversight & Guardrails | Partial |

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 |

Enterprise organizations get single sign-on through the customer's identity provider, user roles that control what each member can see and do, an IP allowlist and audit events. XBOW's console documentation names SOC 2 Type 1, SOC 2 Type 2 and HIPAA, and a trust center sits at trust.xbow.com. The SOC 2, ISO 27001, PCI DSS and NIS 2 line on the homepage describes the customer's compliance requirements, not XBOW's attestations.

| Memory & State Persistence | Not documented |

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 |

| Deployment & Data Residency | Full |

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 |

Pricing
AWS Marketplace: 12-month package of attack credits at $50,000 a year (about $4,167 a month). xbow.com quotes usage based pricing on request.
Attack credits drawn down by testing activity, sold in annual packages.
What is public
The pricing page describes usage-based pricing that scales with coverage and asks for a quote. The AWS Marketplace listing publishes a 12-month package of attack credits at $50,000 (100 centi credits to one attack credit), overage at $0.01 a unit, and a free trial.
Variable cost rationale
Credits are drawn down by testing activity, so spend follows how many assets are tested and how often; the annual package caps the commitment.
Sales call required
Mixed (some tiers require a call)
Free / trial
The AWS Marketplace listing linked from the pricing page offers a free trial on the customer's own applications, and xbow.com itself offers a demo.
Lowest paid plan
12-month attack-credit package, $50,000 a year (AWS Marketplace).
Key ambiguities
xbow.com publishes no prices, so the AWS Marketplace package is the only published figure. Pentest On-Demand (Lightspeed), which had a published starting price, was deprecated on 16 July 2026.
