The verdict

Cobalt is the superior choice for scheduled, human-delivered pentests that produce auditor-ready SOC 2, PCI DSS, and ISO 27001 reports from its vetted Cobalt Core community. Strix excels as the autonomous pentester engineering teams own — a 46,000+ star open-source engine you can self-host and run with your own LLM, chaining exploits across code, APIs, infrastructure, and cloud, and shipping validated findings as merge-ready fix PRs inside CI/CD — starting free.

Best for

Strix

Teams wanting continuous, developer-native autonomous testing

Cobalt

Teams needing scheduled, human-signed compliance pentests

Continuous and yours to run — not a scheduled engagement

Cobalt delivers point-in-time pentests through its own platform and human community. Strix is an open engine you run inside your own workflow, on your own terms.

Own the engine

Strix

Open-source and self-hostable — read the code, extend it, and run the full pentest engine inside your own infrastructure.

Cobalt

Vendor-run SaaS; tests are delivered through Cobalt's platform and there is no self-hostable engine.
Always-on, not point-in-time

Strix

Agents test continuously and on every pull request, so new code is exploited and fixed before it ships.

Cobalt

Pentests are scheduled engagements measured in credits; coverage between tests depends on rescheduling.
Fixes, not just findings

Strix

Every validated finding ships with a merge-ready fix PR in your repo, so remediation lands in the dev workflow.

Cobalt

Findings stream into Jira/GitHub with retests, but remediation is left to your engineers — no auto-fix PRs.

Where each platform wins

Both are real autonomous pentesters. The difference is who they are built for.

Strix key strengths

Open-source core: A 46,000+ star project you can read, run locally, self-host, and extend.

Continuous autonomous testing: Agents run on demand and on every pull request, not just during a scheduled engagement window.

Full-stack coverage: Code, APIs, web apps, infrastructure, and cloud tested from one autonomous pentester.

Workflow-native with auto-fix: GitHub Actions and pull-request testing block vulnerable code, and every finding ships with a merge-ready fix PR.

Free to start: Begin with the open-source core or usage-based hosted plan with no credit card — no per-engagement minimum.

When to choose Strix

Choose Strix if you want continuous, developer-native autonomous pentesting you own — open-source, self-hostable, BYO-LLM, full-stack, and shipping merge-ready fixes inside CI/CD.

Cobalt key strengths

Human-led PTaaS: A vetted Cobalt Core community of 400+ pentesters matched to your stack for manual, expert-driven testing.

Auditor-ready compliance reports: Mature SOC 2, PCI DSS, and ISO 27001 report templates accepted by auditors, with free retests within 6 months.

Fast time-to-engagement: Launch a scheduled pentest in as little as 24 hours with real-time collaboration via Slack and the platform.

When to choose Cobalt

Choose Cobalt if you need a scheduled, human-delivered pentest that produces an auditor-ready SOC 2, PCI DSS, or ISO 27001 report signed off by vetted testers.

Frequently asked questions

Common questions about choosing between Strix and Cobalt.

Strix is better for engineering teams that want continuous, open-source autonomous pentesting embedded in CI/CD with merge-ready fixes, while Cobalt is better for teams that need scheduled, human-delivered pentests producing auditor-ready SOC 2, PCI DSS, or ISO 27001 reports.
