A complete free scan instead of a two scan daily cap
Pentest-Tools.com is a paid online toolkit whose free tier caps you at two scans per day in a limited mode. Its header check rides along inside a broader vulnerability report and barely scratches the configuration layer that attackers actually probe first.
SiteSecurityScore is purpose built for the security configuration layer that attackers probe first, the layer you should never skip. It grades that layer in one instant scan with copy and paste fixes, going far deeper than the header check inside Pentest-Tools. It analyzes the HTTP headers your server sends to browsers, runs deep CSP directive analysis, evaluates your TLS setup, checks DNS authentication records, and audits per-cookie flag combinations, all in seconds with no account required.
SiteSecurityScore gives you everything you need for the configuration layer in one scan, and it is free. There is no scan limit and no signup. Every free scan runs the full analysis, then layers on free continuous daily monitoring with email alerts, a REST API, a Chrome extension for authenticated pages, free header generator tools, and an MCP connector for Claude Code and ChatGPT Codex.

What SiteSecurityScore checks in depth
Pentest-Tools includes a web application scanner that reports on a handful of security headers as part of its vulnerability report. SiteSecurityScore is purpose built for the configuration layer and grades every area below far deeper, handing you a letter grade with copy and paste fixes in seconds.
15+ security headers
Checks all major headers including COOP, COEP, CORP, Origin-Agent-Cluster, and Permissions-Policy, not just the six commonly covered by general scanners.
Deep CSP analysis
Evaluates every directive in your Content Security Policy. Flags unsafe-inline, wildcard sources, missing default-src fallbacks, and configurations that exist but offer little real protection.
DNS security records
SPF, DKIM, and DMARC record analysis including DMARC policy mode and subdomain policy. General pentest tools typically skip this entirely.
Cookie security audit
Checks every cookie for HttpOnly, Secure, SameSite, Path, and Domain attributes. Surfaces session hijacking and CSRF risks at a glance.
TLS/SSL configuration
Protocol version, cipher suites, certificate validity, and HSTS preload status. Covers both the headers that enforce TLS and the underlying configuration.
CORS review
Checks Access-Control-Allow-Origin and related headers for overly permissive cross-origin configurations that could expose sensitive data.
Free tier comparison
The practical gap between the two free tiers is large. Pentest-Tools limits free users to two scans per day in a light scan mode, which skips deep crawling and most active vulnerability checks. Getting full scan results requires a paid subscription starting around $55 per month.
SiteSecurityScore has no scan limit on the free tier and no account requirement. Every free scan runs the full analysis: all headers, full CSP evaluation, TLS configuration, DNS records, and cookie attributes. Paid plans add API access, PDF reports, and monitoring features, but the core analysis is entirely free.
| Free tier | SiteSecurityScore | Pentest-Tools.com |
|---|---|---|
| Daily scan limit | Unlimited | 2 scans/day |
| Account required | No | Yes |
| Full analysis depth | Yes | Light mode only |
| API access | Paid plan | Paid plan |
| Paid plan starts at | Lower tier | ~$55/month |
API access for CI/CD and monitoring
The SiteSecurityScore API returns structured JSON for every scan, covering headers, CSP directives, TLS configuration, DNS records, and cookie data in a single request. Teams use it to catch header regressions before a deployment ships, feed results into compliance dashboards, and pair it with free continuous daily monitoring and email alerts across a portfolio of sites. SiteSecurityScore also ships an MCP connector for Claude Code and ChatGPT Codex, so your AI agents can run a scan and read the grade directly. Pentest-Tools.com has an API only on paid plans.
curl -X POST https://www.sitesecurityscore.com/api/scan \
-H "x-api-key: sss_your_api_key_here" \
-H "Content-Type: application/json" \
-d '{"url": "example.com"}'Free security header generators
Knowing which headers are missing or misconfigured is only the first step. SiteSecurityScore includes free generator tools that produce copy-paste configurations for Apache, Nginx, and Node.js so you can fix findings immediately. Pentest-Tools does not include generation tools.
Scan pages behind login walls
Chrome Extension
Both server-side scanners and pentest platforms can only reach publicly accessible URLs. The SiteSecurityScore browser extension reads real response headers from your authenticated browser sessions. Scan admin panels, staging environments, and internal tools that require a login without any server-side access.

Is SiteSecurityScore a free alternative to Pentest-Tools.com?
Yes, and it is the fastest way to grade and fix the configuration layer attackers probe first. SiteSecurityScore offers unlimited free scans covering 15+ security headers, deep CSP analysis, TLS configuration, DNS security records (SPF, DKIM, DMARC), cookies, CORS, and security.txt, all with no daily limits and no account required. Every scan returns a letter grade with copy and paste fixes in seconds, plus free continuous daily monitoring with email alerts, a REST API, a Chrome extension for authenticated pages, and an MCP connector for Claude Code and ChatGPT Codex. Pentest-Tools.com restricts free users to two scans per day in a limited scan mode, and full vulnerability scanning requires a paid plan starting around $55 per month.
What does SiteSecurityScore check that Pentest-Tools.com does not?
SiteSecurityScore checks 15+ HTTP security headers with deep CSP directive analysis, DNS security records (SPF, DKIM, DMARC), cookie security attributes for every cookie on the page, and CORS configuration. Pentest-Tools.com includes a web vulnerability scanner but focuses on active security testing like port scanning, network enumeration, and OWASP Top 10 vulnerability discovery, which SiteSecurityScore does not do.
How limited is the Pentest-Tools.com free tier?
The Pentest-Tools.com free tier allows two scans per day, limited to a light scan mode that does not perform deep crawling or active vulnerability testing. Full scans, network tools, and API access require a paid plan. SiteSecurityScore has no scan limit on its free tier.
Does SiteSecurityScore have an API?
Yes. SiteSecurityScore provides a REST API that returns structured JSON results for every scan, covering headers, CSP, TLS, DNS records, and cookie data. The API integrates into CI/CD pipelines, monitoring workflows, and compliance dashboards. Pentest-Tools.com also has an API, but it requires a paid subscription.
Why choose SiteSecurityScore over Pentest-Tools.com?
Pentest-Tools.com is a paid toolkit that caps free users at two scans per day in a light mode, with full results starting around $55 per month. SiteSecurityScore is purpose built for the security configuration layer that attackers probe first, the layer you should never skip, and it is the fastest way to grade and fix your posture. One instant scan covers security headers, deep CSP analysis, TLS, DNS, cookies, CORS, and security.txt, free and with no account, and hands you a letter grade with copy and paste fixes in seconds, plus free continuous daily monitoring, a REST API, a browser extension, and an MCP connector.
