Free Pre-Pentest Security Scan
Passive scan of TLS, security headers, cookies, CORS, and DNS against your live URL. Catches the misconfigurations a pentester finds first, with step-by-step fixes.
- Security configuration analysis
- Security headers assessment
- TLS/SSL configuration review
- Cookie security checks
- CORS policy evaluation
- Infrastructure security review

How this fits into penetration testing
This automated penetration test check serves as a first line of defense, identifying common vulnerabilities quickly and cost-effectively. It's perfect for:
- Pre-pentest preparation: Fix obvious issues before launching a full pentest
- Continuous security monitoring: Regular checks between pentests
- Budget-conscious security: Maximize security improvements with limited resources
- Compliance readiness: Identify gaps before audits and assessments
This free passive check is not a pentest. When you are ready for the real thing, Barrion's AI pentest is the direct next step. It is free to start from your dashboard, one fixed price to unlock the full audit-ready report, and it covers business logic flaws and chained attacks with reproducible proof-of-exploit, reviewed by our security team before release. Scoped manual engagements remain an option when you need a deeper, bespoke assessment of a larger estate.
What to do with your results
After running your penetration test check, prioritize remediation based on risk:
- Critical security issues: Address immediately (missing security headers, weak TLS configuration, exposed sensitive information)
- High-risk issues: Fix within 7-14 days (insecure cookies, CORS misconfigurations, security misconfigurations)
- Medium-risk findings: Plan remediation within 30 days (weak TLS, missing security headers)
- Low-risk items: Address during regular maintenance cycles
Document your fixes, retest to verify remediation, and establish a regular scanning schedule. For complex findings or compliance requirements, run a full pentest. Barrion's AI pentest is free to start and confirms what is genuinely exploitable with reproducible proof, with manual engagements as an optional deeper path.
What this penetration test checks
- Security misconfigurations and weak settings
- Missing or improperly configured security headers
- Insecure default configurations
- Exposed sensitive information in headers
- HTTP security headers configuration (CSP, HSTS, X-Frame-Options)
- TLS/SSL certificate health and cipher suite strength
- Cookie security (HttpOnly, Secure, SameSite attributes)
- CORS policy configuration and exposure
- Server information disclosure (version leaks, headers)
- Mixed content and HTTPS enforcement
- Open ports and service exposure
- Subdomain takeover vulnerabilities
- DNS security (DNSSEC, CAA records)
- Email security (SPF, DKIM, DMARC)
- TLS/SSL encryption configuration
- Overall security configuration quality
How Barrion verifies this
The check runs entirely against publicly reachable surfaces, so there is nothing to install and nothing intrusive sent at your origin. Barrion resolves the target, walks the HTTP and TLS handshake, and records the raw response headers, cipher suite, certificate chain, and any redirect hops. That snapshot is then evaluated against a curated rule set drawn from OWASP ASVS, the Mozilla Observatory baseline, and current browser security defaults.
On top of the transport layer, Barrion probes adjacent signals that map to real attacker reconnaissance: DNS hygiene (DNSSEC, CAA, SPF, DKIM, DMARC), cookie attributes on every Set-Cookie response, CORS reflection on common preflight shapes, and information disclosure in server banners and error pages. Findings are de-duplicated per origin and scored by exploitability, not just by header presence.
Every issue ships with the exact evidence that produced it (the offending header, the negotiated cipher, the failing DNS lookup) and a concrete remediation pointing at the config file or platform setting most teams own. That makes the report safe to share with developers and useful as a pre-engagement input for a full pentest, whether that is Barrion's own AI pentest or a manual engagement.
