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, consider engaging professional penetration testers for manual validation and deeper analysis.
How this complements manual 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 engaging professional testers
- Continuous security monitoring: Regular checks between manual assessments
- Budget-conscious security: Maximize security improvements with limited resources
- Compliance readiness: Identify gaps before audits and assessments
For comprehensive security assurance, combine automated checks with professional manual penetration testing for deeper analysis of business logic flaws, complex attack chains, and advanced persistent threats.

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 manual pentest.
Tool-specific questions
What's the difference between this automated check and manual penetration testing?
This security check uses passive scanning to analyze publicly accessible security configurations and identify common security misconfigurations. Manual penetration testing involves certified security experts performing deep, hands-on testing including active vulnerability exploitation, business logic flaws, complex attack chains, and advanced techniques that passive scanning can't detect. Use passive security checks for regular monitoring and configuration review. Use manual penetration testing for comprehensive assessments, compliance, and complex security validation.
How long does an automated penetration test check take?
Most automated checks complete within 2-5 minutes for single-site assessments. Complex applications with multiple endpoints may take 5-10 minutes. This is significantly faster than manual penetration testing, which typically takes 1-3 weeks depending on scope and complexity.
Is this penetration test check safe and non-intrusive?
Yes, our automated penetration test check is completely safe and non-intrusive. We perform passive analysis of publicly accessible information and use read-only techniques. We never attempt to exploit vulnerabilities, access private data, or perform actions that could harm your website or infrastructure. All checks are designed to be safe for production environments.
What types of vulnerabilities can this automated check detect?
Our security check detects configuration issues, security header problems, TLS/SSL misconfigurations, cookie security issues, CORS problems, security misconfigurations, and infrastructure vulnerabilities through passive analysis. We analyze publicly accessible information like HTTP headers, TLS configuration, and DNS records. We do not perform active vulnerability exploitation or attempt to access private data.
Can this replace a professional penetration test?
No, automated checks complement but don't replace professional manual penetration testing. Automated checks are excellent for regular monitoring, initial assessments, and catching common issues. Professional penetration testing provides deeper analysis of business logic flaws, complex attack scenarios, advanced persistent threats, and compliance validation. Use both: automated checks for continuous security monitoring and manual testing for comprehensive assessments.
How often should I run automated penetration test checks?
Run automated checks after any major changes, deployments, or security updates. For ongoing monitoring, weekly checks are recommended. Use Barrion's continuous monitoring for automated daily scans and instant alerts when new vulnerabilities are detected. This ensures you catch regressions quickly and maintain security posture between manual assessments.
Can I use this for compliance and audit requirements?
Yes, automated penetration test checks can help with compliance requirements like PCI DSS, HIPAA, SOC 2, ISO 27001, and GDPR. The reports provide evidence of security controls and can identify gaps in your security posture. However, many compliance frameworks also require periodic manual penetration testing, so combine automated checks with professional assessments for complete compliance coverage.
What should I do if critical vulnerabilities are found?
If critical security issues are detected, prioritize immediate remediation. Apply configuration fixes, verify the remediation, and document the incident. For complex issues or if you're unsure about the fix, consider engaging professional penetration testers or security consultants for guidance. Critical configuration issues like missing security headers, weak TLS settings, or exposed sensitive information should be addressed within 24-48 hours.
Does this work with APIs and web services?
Yes, our automated penetration test check works with web applications, APIs, and web services. It analyzes security headers, CORS policies, TLS configuration, and other publicly accessible security configurations. For comprehensive API security testing, combine automated checks with manual API penetration testing to cover business logic, complex attack scenarios, and authorization testing.
How accurate are automated penetration test results?
Passive security checks are highly accurate for detecting configuration issues, security headers, TLS problems, and security misconfigurations. However, they cannot detect business logic flaws, active vulnerabilities, or advanced attack scenarios that require active testing. Always validate findings and supplement with manual penetration testing for comprehensive security assurance.

FAQ
Frequently asked.
What is Barrion and how does it enhance website security?
Barrion is a security testing and monitoring platform for engineering teams, covering three products: passive DAST that continuously watches your live web apps and APIs, SAST via GitHub that scans your codebase for secrets, insecure patterns and vulnerable dependencies, and AI pentesting that runs active, agent-driven attacks with proof-of-exploit. Findings come with step-by-step fixes you can ship immediately.
How safe is Barrion to use for security testing?
Every default Barrion scan is 100% passive and read-only. We never submit forms, brute-force endpoints or interact with state-changing routes, so it's safe to run against production.
What types of security issues does Barrion identify?
Barrion is a security testing and monitoring platform, so coverage spans three surfaces. Passive DAST flags misconfigurations across TLS/HTTPS, security headers, cookie flags, CORS policy, DNS records, email authentication (SPF/DKIM/DMARC), network exposure and common web hygiene issues. SAST via GitHub finds secrets in code, insecure patterns and vulnerable dependencies. AI pentesting adds exploitable findings like SQL injection, XSS and broken access control with proof-of-exploit.
What specific security checks does Barrion perform?
Barrion checks TLS/HTTPS configuration, HTTP security headers, cookie flags, CORS policy, DNS and email authentication records, network exposure and common web hygiene issues, then prioritises them by severity with clear remediation.
What is Barrion's smart crawling?
Smart crawling automatically discovers the pages and endpoints of your app so scans cover the surface that matters, without you manually listing every URL.
How often does Barrion perform security scans?
Manual scans on demand. Continuous monitoring runs automatically on Essential (weekly+) and Business (daily), and alerts you the moment a new issue appears.
