# Strix vs Astra Security: Continuous Pentesting, Compared

Two continuous pentesting platforms with different engines.

The verdict

Strix is the stronger platform: a 59,000+ star open-source engine whose agents actually chain and exploit findings across code, APIs, infrastructure, and cloud on every run, native to CI/CD with merge-ready fix PRs, free to start. Astra pairs a conventional scanner with scheduled human pentests, so real exploitation depth arrives only during engagement windows.

## Where each platform wins

Both sell continuous security testing. The engines are different.

### Strix key strengths

- **Open-source core:** A 59,000+ star, Apache-2.0 engine you can read, self-host, and run air-gapped.
- **Autonomous exploitation:** Agents chain multi-step attacks and prove impact with working PoCs on every run, not only during scheduled engagements.
- **Workflow-native with auto-fix:** Pull-request testing plus merge-ready fix PRs put findings where developers already work.
- **Your perimeter, your model:** Self-hosted, air-gapped, and BYO-LLM deployments keep code and findings inside your network.

### When to choose Strix

Choose Strix if you want continuous, exploit-validated pentesting from autonomous agents you own, running in CI/CD inside your own perimeter.

### Astra key strengths

- **Human-led pentests included:** Scheduled manual pentests by Astra's team layered on top of continuous scanning.
- **Compliance-friendly packaging:** Auditor-ready reports and certificates aligned to SOC 2, ISO 27001, PCI DSS, and HIPAA.
- **Managed simplicity:** A single subscription with vendor-run scanning, dashboards, and support, no platform to operate.

### When to choose Astra

Choose Astra if you want a managed subscription combining continuous scanning with human-signed pentest reports for compliance, and prefer a vendor-run service over operating your own engine.

## Frequently asked questions

### What is the difference between Strix and Astra Security?

Strix is an open-source autonomous pentester whose AI agents chain and exploit vulnerabilities across code, APIs, infrastructure, and cloud, running in CI/CD with merge-ready fix PRs. Astra Security is a managed PTaaS subscription that pairs a continuous vulnerability scanner with scheduled human-led pentests and compliance reporting.

### Is Strix better than Astra?

For most teams, yes. Strix exploits and proves findings autonomously on every run instead of waiting for a scheduled human engagement, ships merge-ready fix PRs, produces compliance-ready reports, and is open-source, self-hostable, and free to start, none of which Astra offers.

### Does Astra use autonomous AI agents?

Astra positions itself as an AI-powered continuous pentest platform, but its model pairs automated scanning with human pentesters for validation during engagements. Strix's agents autonomously exploit and prove findings on every run.

### Is Strix cheaper than Astra?

Strix has a free open-source core and usage-based hosted pricing with no credit card to start. Astra is sold as an annual subscription, so Strix has a lower entry cost for most teams.

### Can Strix produce compliance reports like Astra?

Yes. Strix generates compliance-ready reports aligned to SOC 2, ISO 27001, and PCI DSS, with continuous evidence across the audit period rather than a point-in-time engagement snapshot.
