For developers
Security tooling that respects your time.
Security that integrates with the workflow you already use: GitHub, PRs, Slack. Across 7,440 recent scans, 98.9% are missing a strict CSP and 57.2% have no HSTS preload. Both surface in the first 60 seconds. Findings come with context. Remediations come with code.
What you get
From URL to a PR fix, without leaving GitHub.
DAST
Live-app scanning
Continuous, production-safe checks across TLS, headers, CORS, cookies, DNS, email auth, network exposure, and 30+ more. No payloads, no surprises.
Monitoring
Regressions caught between releases
Scheduled re-scans on the cadence you pick. When the score drops or a new finding appears, it lands in email, Slack, or Teams instead of a dashboard nobody opens.
AI fixes
Remediation PRs
Barrion can open a fix PR for select finding classes. You review the diff, run the tests, merge. No black-box auto-merge.
AI pentest
Active testing on demand
When you want more than passive checks, an agent works the app end to end and returns reproducible proof-of-exploit. Self-serve, paid in credits.
Stack-aware
Framework-specific guidance
Remediation steps written for Next.js, Django, Laravel, Express, Rails, and the rest of the stack you actually use.
Honest
Open about what we run
Every check has a documented scope. The DAST engine builds on ZAP, we credit it and don't pretend otherwise.

FAQ
Security tooling for developers, answered.
What frameworks does the remediation guidance cover?
Barrion detects the stack behind your app and writes the fix in that framework's idiom rather than generic OWASP boilerplate. Remediation is tuned for Next.js, Django, FastAPI, Laravel, Express, Rails, NestJS, and Spring Boot, plus the server and edge layers (Nginx, Apache, IIS, Cloudflare Workers). Anything outside that list still gets stack-agnostic steps you can apply directly.
What does the GitHub integration actually do?
It turns a finding into a pull request. Connect the repositories you want, and when a scan surfaces something fixable in code or config, Barrion can open a PR with the change already written for your stack. It is a one-way door you control: Barrion opens the PR, you review the diff and merge. Nothing runs on your pull requests and nothing gates your pipeline.
Will Barrion open PRs against my code without permission?
No. AI remediation PRs are explicitly opt-in per finding. When you click 'Open fix PR' on a finding, Barrion creates a draft PR with the suggested change for your review. You approve, run your tests, and merge, Barrion never bypasses your review process. The feature is also rate-limited per plan (5 PRs/month on Essential, unlimited on Business) so you control the cadence.
Does the GitHub integration work with private repositories?
Yes. Barrion never scans your repository. The GitHub integration only touches repositories you explicitly grant, to open remediation pull requests, and private repos work identically to public ones. Repository contents are fetched on demand to write a remediation PR and are not persistently stored beyond what that requires, as described in Section 28 of our Legal Terms.
Does Barrion replace a real security review?
For the large majority of it, yes. Continuous coverage handles OWASP Top 10 patterns, misconfigurations, missing headers, and vulnerable dependencies, and Barrion's on-demand AI pentest goes further into business-logic abuse and multi-step attack chains with reproducible proof-of-exploit. Human pentests remain optional for bespoke creative depth and threat-modeling exercises. AI pentests are self-serve from your dashboard, paid in credits.
