Terms of Service

Last updated: 2026-02-26

The Short Version

VulWall continuously scans your public-facing infrastructure to help you find and fix security issues before attackers do. You are responsible for only scanning domains you own or have permission to scan. We work hard to deliver accurate results, but no tool catches everything. Use our service responsibly and in compliance with applicable laws.

What VulWall Does

VulWall is an automated security scanning service. We help you identify potential vulnerabilities in your public-facing infrastructure by analyzing:

  • Domain and subdomain configurations
  • SSL/TLS certificates and encryption
  • Security headers and web server settings
  • Open ports and exposed services
  • Known vulnerabilities (CVEs) in detected software

VulWall performs non-intrusive external security scanning. This includes DNS lookups, SSL/TLS analysis, TCP port scanning, HTTP request-based vulnerability detection, and security header analysis. We access only publicly reachable services and do not attempt to exploit vulnerabilities, gain unauthorized access, or perform denial-of-service testing. Our scanning may be detected by intrusion detection systems and WAFs on the target infrastructure. This is normal behavior for security scanning tools and does not indicate any harmful activity.

Your Responsibilities

You Must Own or Control What You Scan

By using VulWall, you confirm that for every domain you scan, you either:

  • Own the domain, or
  • Have explicit written permission from the owner to scan it

Scanning domains without authorization may violate laws in your jurisdiction. You are solely responsible for ensuring you have proper authorization.

Account Security

You're responsible for keeping your account credentials secure. Don't share your password, and let us know immediately if you suspect unauthorized access to your account.

Acceptable Use

You agree not to:

  • Use VulWall to scan domains you don't own or have permission to scan
  • Attempt to bypass any security measures or rate limits
  • Resell or redistribute VulWall services without permission
  • Use scan results to exploit vulnerabilities or harm others
  • Upload malware or attempt to compromise our systems
  • Violate any applicable laws or regulations

Service Limitations

While we work hard to provide accurate and useful security assessments, you should understand:

  • We can't find everything. No automated scanner catches 100% of vulnerabilities. VulWall is a tool to help improve security, not a guarantee of it.
  • Results are point-in-time. Your security posture can change. Regular scanning is recommended.
  • False positives happen. Some findings may not apply to your specific configuration. Always verify before acting.
  • No single tool catches everything. VulWall provides the continuous monitoring layer that periodic penetration tests cannot. Together, they form a comprehensive security program.

Data Processing

We take data protection seriously. When we process data on your behalf through our scanning service, we do so as a data processor under GDPR Article 28, with full contractual safeguards. Our Data Processing Agreement (DPA) is available upon request at contact@vulwall.com. For details on what data we collect and how we handle it, see our Privacy Policy.

Disclaimer of Warranties

We stand behind our product, but we need to be upfront about legal realities. VulWall is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to:

  • Merchantability or fitness for a particular purpose
  • Accuracy or completeness of scan results

Limitation of Liability

We keep our liability terms fair and straightforward. To the maximum extent permitted by law, VulWall and its team shall not be liable for:

  • Any indirect, incidental, special, or consequential damages
  • Loss of profits, data, or business opportunities
  • Security breaches that occur despite our scanning
  • Actions taken based on scan results

Our total liability for any claims shall not exceed the greater of (a) the amount you paid us in the 12 months preceding the claim, or (b) EUR 100. This limitation does not apply to liability that cannot be excluded or limited under applicable law, including liability for intentional misconduct or gross negligence.

Indemnification

This section applies if your misuse of VulWall causes a problem for us or others. You agree to indemnify and hold VulWall harmless from any third-party claims, damages, or expenses (including reasonable legal fees) arising from:

  • Scanning domains without proper authorization from the domain owner
  • Your violation of these terms
  • Your violation of applicable law in connection with your use of the service

These terms are governed by the laws of the Netherlands. Any disputes shall be resolved in the courts of Amsterdam, the Netherlands.

Force Majeure

Neither party shall be liable for delays or failures in performance resulting from causes beyond its reasonable control, including natural disasters, internet outages, or third-party service failures.
