Barrion scans a live web app or API for more than 35 common security misconfigurations — missing security headers, weak TLS, exposed CORS rules, outdated JavaScript libraries — and turns the results into a plain-language fix list, including AI-generated pull requests it can open directly on a connected GitHub repo.
Barrion offers a free plan for basic passive scanning, with the Essential plan unlocking the full 35+ check scanner, GitHub AI fixes, and compliance reporting from €199 a month.
What is Barrion?
Barrion is grouped with Security & Compliance tools, and positioned as an alternative to Acunetix, Nessus, and Snyk — established scanning and dependency tools typically priced and built for larger security teams. The company, Barrion, is a pre-seed startup based in Gothenburg, Sweden, founded in February 2025 by Mikael Karlgren, and currently runs as a team of 1-10 people.
The problem it targets is one most small teams recognize but don’t budget for: security scanning and remediation that doesn’t require a dedicated security hire or a full enterprise contract. Barrion runs passive, read-only checks against production without altering anything, then hands back fixes a developer can act on immediately rather than a raw list of findings to research. The company describes its approach as combining passive scanning of live applications with codebase analysis on GitHub pull requests, so issues can surface before a change even merges, not just after it’s deployed.
Key features
Catch every vulnerability before you ship
A single scan checks HTTPS, TLS, HSTS, CSP, and header configuration across live web apps and APIs, runs 35+ passive checks for issues like XSS, clickjacking, and MIME-sniffing exposure, and validates certificates and email authentication records — SPF, DKIM, DMARC — without touching production.

Fix issues with AI-generated PRs
Every finding comes with a step-by-step, plain-language fix, and Barrion can generate AI Fix pull requests directly in a connected GitHub repo so remediation moves from report to shippable code without manual rewriting, following safe CSP rollout guidance to avoid breaking the site.
Stay ahead of new threats automatically
Domains can be scheduled for recurring scans with alerts the moment a new vulnerability appears, delivered over email, Slack, or Microsoft Teams, with a security score tracked over time to catch configuration drift before it turns into an actual breach.
Share audit-ready reports
Board-ready PDF and CSV reports align findings with SOC 2, ISO 27001, and PCI DSS frameworks, reference OWASP and CIS Controls for context, and can be shared directly with auditors or stakeholders to demonstrate ongoing security hygiene between formal reviews.
Plans and pricing
Barrion offers a free plan plus the Essential plan, billed monthly or annually, with a custom Business plan for teams that need continuous pentesting and multi-domain coverage. Pentest credit top-ups are available separately on any plan.
| Plan | Price | Billing | Key limits |
|---|---|---|---|
| Free | €0 | — | 18 checks/scan, 5 scans/day, 3 pages/scan, no pentest credits |
| Essential | €199/mo (~€1,591/year billed annually) | Monthly or annual | 410 pentest credits/month, 35+ checks/scan, 50 scans/day, 20 pages/scan, weekly scans on 1 domain, email alerts |
| Business | Custom pricing | Contact sales | Continuous AI pentesting, volume credit discounts, API access, daily scans across 10 domains, Slack & Teams alerts, priority support |
Top-up pentest credits are also available at €0.50 each, in packs of 100 to 2,000+, valid for 12 months from purchase.
Who it’s best for — and who should skip it
Barrion fits developers, IT and security agencies, and small businesses — exactly the audience shipping fast without a dedicated security hire, where a read-only scan plus an AI-generated fix is enough to close most common gaps before launch.
It’s a weaker fit for teams that need authenticated or active penetration testing included by default on the entry plan, since deeper pentest coverage draws on credits or the custom Business tier, or for larger organizations that will want more than 1 continuously monitored domain. Agencies managing several client sites are a reasonable fit on Business, provided the monitoring cadence and Slack or Teams alerts match their needs. Buyers should also weigh that Barrion is a pre-seed company barely a year and a half old, with a correspondingly short public track record.
What users say
Barrion’s review count is still small — just 2 reviews at the time of writing — averaging 4.5 out of 5. Both are detailed and positive: one buyer says the scan flagged real vulnerabilities in their app within minutes of setup and that the AI-generated instructions were clear enough to hand straight to a coding assistant for fixes.
A second review praised fast scans and remediation guidance that doesn’t require security expertise to interpret, while flagging early rough edges — a thin company story and missing third-party license attributions. The founder’s reply confirms the team addressed those items, adding clearer founder context and documentation, which is a reasonable early signal even with so few public reviews to draw on.
Price and value
At €199 a month, Essential lands in a similar range to established scanners like Acunetix once you account for ongoing license and seat costs, and the AI-generated GitHub PRs add real value by skipping the step where a developer has to translate a finding into a fix themselves. The free plan is a reasonable way to test the core scanning experience before committing to a paid tier. The main risk isn’t price — it’s newness: with only two public reviews and a pre-seed company behind it, buyers are betting on a young team’s continued responsiveness more than a long track record.
Verdict
Barrion turns a 35-point security scan into fixes a developer can ship immediately, including AI-generated GitHub pull requests, backed by compliance reporting that larger scanners charge more for — the tradeoff is a brand-new, pre-seed company with only a handful of public reviews so far.
Frequently asked questions
Barrion has a free plan, then Essential at u20ac199/month (or roughly u20ac1,591/year with the annual discount), plus a custom-priced Business plan for larger pentest programs.
Yes. The free plan includes 18 checks per scan, 5 scans a day, and 3 pages per scan, with no pentest credits included.
Barrion doesn't publish a blanket refund guarantee; contact Barrion support directly about billing or cancellation before upgrading.
Yes, scan alerts can be routed to Slack or Microsoft Teams on the Business plan; Essential includes email alerts.
Barrion works well as an alternative to both; it's a lighter, AI-fix-focused scanner aimed at teams without a dedicated security budget rather than a full enterprise platform.
Essential includes 410 monthly pentest credits, 35+ checks per scan, 50 scans a day, 20 pages per scan, and weekly passive monitoring of 1 domain.
No, its scans are read-only and don't alter production.
Yes, PDF and CSV reports reference SOC 2, ISO 27001, PCI DSS, OWASP, and CIS Controls.
