Tool Comparison
WarDek vs SecurityHeaders.com: Security Scanner Comparison 2026
SecurityHeaders.com and WarDek both provide instant security assessment, but at very different scopes. SecurityHeaders.com is a fast, focused tool that checks one thing exceptionally well: your HTTP security headers. WarDek scans across 10 security dimensions — including headers — and adds compliance assessment, vulnerability detection, email security, and AI-powered remediation advice.
SecurityHeaders.com is the perfect "quick check" tool — you get an instant grade in under 3 seconds. But if you need to understand your full security posture, generate reports for compliance, or go beyond headers, WarDek provides the comprehensive assessment.

Frequently Asked Questions
Does WarDek check the same headers as SecurityHeaders.com?
Yes. WarDek analyzes all the same HTTP security headers including Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy, and X-XSS-Protection (deprecated but still checked). WarDek also evaluates CSP directive quality (not just presence) and checks additional headers like Cross-Origin-Opener-Policy and Cross-Origin-Resource-Policy.
SecurityHeaders.com gives me an A+. Do I still need WarDek?
An A+ on SecurityHeaders.com means your HTTP headers are well-configured — congratulations. However, headers are just one dimension of website security. Your site might still have SSL misconfigurations, vulnerable JavaScript libraries, exposed sensitive files, missing email authentication (SPF/DMARC), or compliance gaps. WarDek checks all of these in addition to headers.
Why is SecurityHeaders.com faster than WarDek?
SecurityHeaders.com makes a single HTTP request and analyzes the response headers. WarDek performs 10 different scans (headers, SSL, vulnerabilities, email DNS, exposed files, CORS, cookies, technology fingerprinting, AI security, and compliance assessment), which requires multiple requests and analysis steps. The additional scan time delivers significantly more comprehensive results.
Can I use SecurityHeaders.com and WarDek together?
Absolutely. Many security professionals use SecurityHeaders.com as a quick daily check for header configuration and WarDek for periodic comprehensive assessments. SecurityHeaders.com is ideal for rapid iteration when configuring headers; WarDek is ideal for full security audits and compliance reporting.
Does SecurityHeaders.com check for NIS2 or GDPR compliance?
No. SecurityHeaders.com focuses exclusively on HTTP security headers. While proper header configuration contributes to compliance requirements (encryption in transit, clickjacking protection, etc.), comprehensive NIS2 and GDPR compliance involves many additional controls that SecurityHeaders.com does not assess. WarDek provides built-in compliance assessment for NIS2, GDPR, and the EU AI Act.
