What to do with compliance check results
After running a compliance check, use the results to improve your compliance posture:
- Prioritize gaps: Focus on critical compliance gaps first
- Create remediation plan: Address findings with specific timelines
- Document improvements: Maintain evidence of compliance efforts
- Schedule follow-up checks: Regular checks ensure continuous compliance
- Prepare for audits: Use reports as evidence for formal audits
For formal compliance certification, ensure all findings are addressed and documented. Use compliance reports as evidence of security controls and continuous improvement. Consider engaging compliance consultants or auditors for formal validation.
Why compliance checking matters
Regular compliance checking helps you maintain security standards and prepare for audits. This tool provides:
- Pre-audit preparation: Identify gaps before formal compliance audits
- Continuous monitoring: Track compliance posture over time
- Risk management: Understand compliance risks and prioritize remediation
- Documentation: Generate compliance reports for stakeholders
- Remediation guidance: Get actionable steps to address compliance gaps
Use this compliance checker for regular assessments, pre-audit preparation, and continuous compliance monitoring. Combine with internal assessments and professional audits for comprehensive compliance coverage.
How Barrion verifies this
Barrion approaches compliance from the outside in. The scan checks the controls it can observe from outside (TLS configuration, security headers, cookie attributes, transport encryption), which are the technical basics PCI DSS, HIPAA, SOC 2, ISO 27001, and GDPR all expect. Findings aren't tagged with specific framework requirements, so you cite them against the relevant control yourself.
With monitoring on a paid plan, the scan runs on a schedule. When a deploy drops a header or weakens a cipher suite, Barrion catches the regression on the next scheduled scan. That turns compliance from a yearly fire drill into a live signal you can act on before an auditor or customer questionnaire forces the conversation.
The output is built for both audiences: developers get a concrete remediation snippet for the offending control, while compliance owners get a report that supports their evidence collection. Policy and procedural controls still need human review, but everything Barrion can verify from outside the perimeter is verified automatically.
Tool-specific questions
What does a compliance checker test?
A security compliance checker tests the technical controls that PCI DSS, HIPAA, SOC 2, ISO 27001, and GDPR expect. It identifies gaps, such as missing TLS enforcement, insecure headers, or cookie issues, that could fail a compliance audit. Barrion's free tool gives you prioritized findings with remediation steps, so you can fix issues before your next audit.
Can this tool provide formal compliance certification?
No, our compliance checker identifies security gaps and provides guidance, but formal compliance certification requires professional audits and validation by certified auditors. Use our tool for pre-audit preparation and continuous compliance monitoring.
How often should I run compliance checks?
Run compliance checks quarterly for ongoing monitoring, before compliance audits, and after major changes or security incidents. Use Barrion's continuous monitoring for scheduled security checks, up to daily, and get instant alerts when compliance issues are detected.
What compliance standards does this checker evaluate?
Our compliance checker evaluates technical security controls relevant to PCI DSS, HIPAA, SOC 2, ISO 27001, GDPR, and other major compliance frameworks. For PCI DSS, we check secure transmission of cardholder data (TLS/SSL configuration), security headers and encryption requirements, and network security configuration. For HIPAA, we evaluate transmission security (TLS/SSL) for protected health information (PHI) and security configuration quality. For SOC 2, we assess security controls configuration, availability and processing integrity indicators, and confidentiality and privacy technical controls. For ISO 27001, we check cryptography and encryption configuration (TLS/SSL) and network security controls. For GDPR, we evaluate technical security controls (TLS/SSL encryption) and security of processing configuration. Note that full compliance requires additional policy, procedural, and organizational controls beyond technical configuration.
What's the difference between compliance checking and security auditing?
Compliance checking evaluates your security controls against specific compliance standards (PCI DSS, HIPAA, etc.). Security auditing evaluates your overall security posture. Compliance checks focus on meeting regulatory requirements, while security audits focus on security effectiveness.
Can I use compliance reports for customer security questionnaires?
Yes, compliance reports can help answer customer security questionnaires and demonstrate your security commitment. They provide evidence of security controls and compliance efforts. Supplement with additional documentation as needed for specific requirements.
What should I do if compliance check shows gaps?
If compliance checks show gaps, prioritize remediation based on risk and compliance requirements. Create a remediation plan, assign owners, set timelines, and track progress. For critical gaps, consider engaging compliance consultants or professional auditors for guidance.
Does this replace professional compliance audits?
No, our compliance checker complements but doesn't replace professional audits. Use it for regular monitoring, pre-audit preparation, and continuous compliance assessment. Professional audits provide deeper analysis, policy review, and formal compliance validation.
How accurate are compliance check results?
Our compliance checker evaluates technical security controls accurately, but compliance involves policies, procedures, and organizational controls that require manual review. Use our tool for technical security checks and combine with internal assessments for comprehensive compliance coverage.
Can this help with PCI DSS compliance?
Yes, our compliance checker evaluates security controls relevant to PCI DSS requirements including secure transmission (TLS/SSL), encryption configuration, and vulnerability detection. However, formal PCI DSS compliance requires a Qualified Security Assessor (QSA) and comprehensive assessment.
What compliance evidence does this tool provide?
Our compliance checker provides evidence of security controls, gap analysis reports, remediation recommendations, and compliance posture documentation. Use these reports as evidence of security controls and continuous improvement efforts for compliance audits.

FAQ
Frequently asked.
What is Barrion?
Barrion runs continuous, agentic AI penetration tests of web applications and APIs. AI agents test your app the way an attacker would, safely, on a schedule or on demand. Findings are checked against the live app before they're reported, and tracked across runs as new, still open, resolved or regressed. From Standard level up, a security engineer reviews each report. Barrion AB is based in Gothenburg, Sweden. A free passive scan is the quickest way to start.
How safe is Barrion to use for security testing?
AI pentests send real test requests, so they're rate-limited and non-destructive, and you approve the exact scope before a single request goes out. You can point them at staging too. The free passive scan only reads your live app. It never submits forms, brute-forces endpoints or touches anything that changes state, so it's safe to run against production.
What types of security issues does Barrion identify?
AI pentests look for the issues an attacker could exploit, like SQL injection, cross-site scripting and broken access control. Findings are checked against your live app, and confirmed ones come with the request and response that prove them. Anything we couldn't confirm is clearly marked and capped in severity. The passive scan catches misconfigurations in TLS and HTTPS, security headers, cookie flags, CORS policy, DNS records, email authentication (SPF, DKIM, DMARC) and network exposure.
What specific security checks does Barrion perform?
Barrion covers two surfaces. AI pentesting is the active part: specialist agents chain requests to find exploitable flaws such as SQL injection, cross-site scripting and broken access control. Findings are checked against your live app, and confirmed ones come with the request and response that prove them. The passive scan is read-only and safe to point at production. On paid plans it runs 35+ checks (18 on the free plan): transport security (HTTPS, HSTS, TLS version, cipher suites, certificate expiry, hostname and chain validity, OCSP stapling), HTTP response headers (Referrer-Policy, Permissions-Policy, X-Content-Type-Options, Content-Type, server information disclosure), CSP and framing (Content-Security-Policy, bypass detection, Trusted Types, X-Frame-Options), cross-origin policy (COOP, COEP, CORP and the full CORS header set), cookie flags and anti-CSRF tokens, mixed content, vulnerable JavaScript libraries, DNS records including DNSSEC and CAA, email authentication (SPF, DKIM, DMARC), open ports and subdomain takeover. Findings from both are ranked by severity and come with step-by-step remediation.
Will our auditor or enterprise customer accept the report?
The report maps every finding to OWASP WSTG, a security engineer reviews it from Standard up and signs it off from Deep up, and a free retest shows what you fixed. Teams use it as evidence for SOC 2, ISO 27001 and NIS2 work. Whether it's accepted is up to your auditor.
How often does Barrion test my app?
Continuously or on demand. On the Business plan you save a pentest and it reruns daily, weekly, monthly, quarterly, every six months, yearly or on your own rhythm. On any plan you can start a pentest or a passive scan on demand. A passive scan also runs on a schedule and alerts you when something new shows up.
Is Barrion suitable for security testing of all business sizes?
Yes. Solo developers often start with the free passive scan and a single pentest. Teams with several apps run pentests on a schedule, and it fits alongside the tools you already run.
How does Barrion handle data security and privacy during security testing?
Passive scans are read-only: they only look at what your app already exposes publicly. For AI pentests we store the findings and the evidence behind them, the requests and responses that confirm each issue, so you can review and reproduce them. Test credentials you add are encrypted. Data is stored and hosted in Sweden and AI processing runs in the EU. Our trust page lists every subprocessor. Pentests are rate-limited and only run inside the scope you approve.
What if I'm not satisfied with Barrion's security testing service?
You can cancel anytime in the dashboard, and paid plans carry a 14-day refund window from the first charge. If something isn't right, contact us and we'll make it work for your team.
How does Barrion help with SOC 2, ISO 27001, NIS2, and other compliance frameworks?
Barrion's pentest reports come as PDF, XLSX and JSON, mapped to all 97 OWASP WSTG test cases, with engineer review from Standard up, sign-off from Deep up and a free retest after fixes. Teams use them as evidence that supports SOC 2, ISO 27001, PCI DSS and NIS2 work. Whether a report is accepted is up to your auditor or customer.
