The verdict
XBOW is the superior choice for one narrow case: a fully hands-off, vendor-run pentest engagement where you're comfortable with sensitive security data living in XBOW's cloud — it's a proven platform, #1 on HackerOne with 1,060+ validated findings. Strix excels as the autonomous pentester most teams actually own: a 25,000+ star open-source engine you can self-host and run fully air-gapped with your own LLM, native to CI/CD and pull requests with merge-ready fix PRs, and covering code, APIs, infrastructure, and cloud — starting free.

Built to run inside your perimeter
For regulated and data-sensitive enterprises, the question isn't only how deep the testing goes — it's where it runs and who controls it.
Runs in your environment
Strix: Open-source and Docker-based — deploy Strix self-hosted or fully air-gapped inside your own infrastructure.
XBOW: Delivered as SaaS. Even XBOW's managed-hosted tier runs on vendor-provisioned cloud, not your network.
Your data never leaves
Strix: Source code, credentials, and exploit proof-of-concepts stay inside your perimeter. Bring your own LLM, including fully local models.
XBOW: Security-sensitive findings, credentials, and PoCs are stored and processed in XBOW's cloud, with prompts sent to third-party model providers.
You own the blast radius
Strix: Define the rules of engagement and run every agent in an isolated sandbox you control and can audit end to end.
XBOW: Thousands of agents execute live attacks from a vendor-operated attack machine, under the vendor's controls rather than yours.
Where each platform wins
Both are real autonomous pentesters. The difference is who they are built for.
Strix key strengths
Open-source core: A 25,000+ star, Apache-2.0 project you can read, run locally, and self-host.
Built into the dev workflow: GitHub Actions and pull-request security reviews block vulnerable code before it merges.
Auto-fix with merge-ready PRs: Every validated finding ships with a reproduction and a ready-to-merge fix pull request.
Runs inside your perimeter: Open-source and Docker-based — deploy self-hosted or fully air-gapped with a local LLM, so code, credentials, and findings never leave your network.
Full-stack coverage: Code, APIs, web apps, infrastructure, and cloud tested from one platform.
Free to start, zero data retention: Connect repos and domains with no credit card; source code is never stored or used for training.
When to choose Strix
Choose Strix if you want autonomous pentesting that runs inside your own perimeter — open-source, self-hostable or air-gapped, CI/CD-native, with merge-ready fixes and continuous coverage. The fit for regulated and data-sensitive enterprises that can't send code and findings to a vendor cloud.
XBOW key strengths
Managed compliance engagements: Audit-ready reports for SOC 2, ISO 27001, HIPAA, GDPR, and 40+ frameworks within five business days.
HackerOne-validated depth: Reached #1 on the HackerOne leaderboard with 1,060+ submitted production vulnerabilities.
Massive parallel agent scale: Thousands of short-lived agents coordinated for deep, vendor-run enterprise assessments.
When to choose XBOW
Choose XBOW if you want a fully hands-off, vendor-run pentest delivered as an audit-ready compliance report and are comfortable with security-sensitive data residing in the vendor's cloud.
Frequently asked questions
Common questions about choosing between Strix and XBOW.
Is Strix better than XBOW?
Strix and XBOW are both autonomous pentesters built for different buyers. Strix is better for engineering teams that want open-source, CI/CD-native testing with merge-ready fixes, while XBOW is better for enterprises that want a managed, audit-ready compliance engagement.
What is the difference between Strix and XBOW?
Strix is an open-source platform you run inside your own development workflow, with pull-request reviews and auto-fix PRs across code, APIs, infrastructure, and cloud. XBOW is a vendor-run service that delivers on-demand, compliance-ready pentest reports for web applications and APIs.
Is Strix cheaper than XBOW?
Strix offers a free open-source core and usage-based hosted pricing with no credit card to start. XBOW lists per-test pricing from $4,000 to $8,000 with Enterprise plans by quote, so Strix has a lower entry cost for most teams.
Can Strix replace XBOW?
Strix can replace XBOW for teams that want continuous, workflow-embedded pentesting and self-hosting. Organizations that specifically need a fully managed engagement with a vendor-delivered compliance report may still prefer XBOW for that motion.
Can XBOW run on-premises or self-hosted?
No. XBOW is delivered as SaaS; its enterprise options are managed single-tenant hosting and regional data residency, but security-sensitive data is still stored and processed in XBOW's cloud. Strix is open-source and can run self-hosted or fully air-gapped inside your own infrastructure with a local LLM.
Which is better for regulated or data-sensitive enterprises, Strix or XBOW?
Strix is the better fit for regulated and data-sensitive enterprises because it runs inside your own perimeter — source code, credentials, and exploit proof-of-concepts never leave your network, and you can bring your own LLM. XBOW stores and processes that security-sensitive data in its own cloud.
Who should use XBOW instead of Strix?
Enterprises that want a hands-off, managed pentest delivered as an audit-ready report mapped to SOC 2, ISO 27001, and 40+ frameworks, and that prefer a vendor-run engagement over operating their own platform, are a good fit for XBOW.
