Security teams seeking scalable, repeatable application and API penetration testing with validated exploits and actionable remediation guidance.

Overview

XBOW is an autonomous offensive security company helping organizations strengthen cyber defense for the AI era. By combining AI reasoning with offensive security workflows, its platform delivers expert-level security testing at machine speed. XBOW enables security teams to move from reactive response to proactive defense—using autonomous offense to identify weaknesses before attackers exploit them.

The problem it solves

Most organizations can only afford to pentest a small share of the applications and APIs they expose, and only a few times a year, while code ships every week. Scanners and static analysis produce thousands of unverified findings, leaving teams unsure which flaws are actually exploitable. XBOW applies autonomous offensive testing so more of the attack surface is tested more often, with findings backed by working proof.

Core capabilities

Autonomous pentesting of web applications and APIs that discovers, chains, and exploits vulnerabilities.
Validated findings delivered with the working exploit, request, response, and reproduction steps.
Deterministic checks to confirm findings in generally available vulnerability classes, with preview classes labeled.
Continuous or on-demand testing that returns first validated findings in hours.
Automatic retesting after fixes are deployed to confirm remediation.
Scale to assess large application portfolios rather than only the highest-priority systems.

Ideal customer profile

Mid-market and enterprise security and application security teams with many internet-facing applications and APIs, frequent release cycles, and a need to extend testing coverage beyond what periodic manual pentests can reach. A strong fit is a team that wants validated, prioritized findings it can hand directly to engineering.

Use cases

Extend pentest coverage across the full application portfolioValidate exploitability before prioritizing remediationTest new releases between scheduled manual pentestsRetest fixes and confirm remediationReduce false positives from scanners and static analysisSupport continuous offensive testing for AppSec programs

Why CYBER BUYER is featuring this vendor

XBOW represents a new category of autonomous offensive security that can widen testing coverage and speed up validation without adding headcount. CYBER BUYER features it for buyers who want to compare autonomous pentesting against traditional services, scanners, and bug bounty programs, and who need help defining scope, safety controls, and success measures before purchase.

Questions to ask during evaluation

Which application, API, and authentication types can XBOW test today, and which are in preview?
What safety controls prevent disruption to production systems, and can testing be limited by scope, time window, or rate?
How are findings validated, and what is the observed false-positive rate in environments like ours?
How does XBOW handle authenticated testing, multi-step workflows, and business-logic flaws?
How do findings integrate with our ticketing, vulnerability management, and CI/CD tools?
How is retesting triggered, and how is remediation evidence reported for audits?
Where does testing data, including captured requests and responses, reside, and how is it protected and retained?
How does XBOW complement or replace our current manual pentests and bug bounty program, and how is the subscription scoped and priced?
