60+ automated vulnerability checks across 15 categories — covering the types of vulnerability that security teams care about most in modern web apps.
Unlike basic scanning tools, our web vulnerability scanner crawls up to 10 pages on your site to detect vulnerabilities across your entire web application — not just the homepage.
Verify your SSL certificate, check for mixed content, HTTPS redirects, and HSTS on your web server — the foundation of secure data transit and strong security posture.
Run vulnerability checks on CSP, HSTS, X-Frame-Options, Permissions-Policy, Referrer-Policy, and more. Get exact configuration recommendations to fix security issues.
Detect unsafe JavaScript patterns, inline eval(), document.write(), innerHTML usage, and potential cross-site scripting — common web application vulnerabilities in source code.
Verify forms have CSRF tokens and cookies have proper SameSite, HttpOnly, and Secure attributes. Check access controls to prevent cross-site request forgery attacks.
Detect exposed .env files, .git repositories, database backups, debug logs, open ports, and 14+ other commonly leaked paths that penetration testers look for first.
Identify outdated jQuery, AngularJS 1.x, old Bootstrap, and unpatched software with known vulnerabilities — the kind of vulnerability discovery that prevents real breaches.
Every vulnerability comes with a clear, developer-friendly explanation and exact code snippets. No manual testing or security jargon — just step-by-step remedies.

For indie hackers & small security teams
Full vulnerability management platform
There are many commercial and open source vulnerability scanners on the market — from enterprise-grade DAST tools to open source tools like Nikto web server scanner and OpenVAS. Here's how we fit in.
Tools like Burp Suite are powerful but complex — built for penetration testers and security teams with deep expertise. OpenVAS is a powerful open source vulnerability scanner designed for network-level vulnerability scanning across infrastructure. SAST tools analyze source code for flaws (static application security testing), while DAST tools like our scanner test running applications from the outside (dynamic application security testing). Commercial tools from major vendors or scanning tools by listing can cost thousands per year.
SecureSaaS is built specifically for web app security. Vulnerability scanners are automated tools that scan web applications for common flaws — and ours does exactly that, without the steep learning curve. No CLI setup, no false positives to wade through, no manual testing required. Just paste your URL and get actionable results. Unlike a web application security scanner aimed at enterprise, we're designed for SaaS builders, indie hackers, and small security teams who need fast, reliable application security testing.
Common questions about our web vulnerability scanning tool
A website vulnerability scanner is an automated tool that scans web applications for security flaws. It crawls your site, analyzes pages for known vulnerabilities like XSS, CSRF, missing security headers, SSL misconfigurations, and exposed files. SecureSaaS runs 60+ automated vulnerability checks and generates a report with severity ratings and fix suggestions.
Our scanner covers a wide range of web application vulnerability categories: SSL/TLS issues, missing or misconfigured security headers, cross-site scripting (XSS), cross-site request forgery (CSRF), cookie security flaws, sensitive file exposure, outdated libraries with known vulnerabilities, CORS misconfigurations, open redirects, SPF/DMARC email security, and more — covering the OWASP top 10 risks.
Yes — every account starts with 3 free scan credits. Run a complete website vulnerability scanning session with full results, severity scores, and vulnerability descriptions at no cost. Upgrade to Starter ($29/mo) or Pro ($79/mo) to unlock fix suggestions, PDF exports, and more credits.
Burp Suite is a comprehensive web application scanner and testing tools platform built for penetration testers and security professionals. Nikto is an open source web server scanner focused on server-level checks. SecureSaaS provides automated scanning focused on web app security — no installation, no CLI, no steep learning curve. Think of it as application security testing made simple for developers.
Not at all. Unlike commercial tools that require expertise in penetration testing or security check configurations, SecureSaaS is designed for developers and SaaS builders. Just enter your URL and our security scanner handles the rest — vulnerability discovery, severity scoring, and actionable remedies you can implement immediately.
Yes. Our scanner is tuned specifically for modern web apps and SaaS platforms, which significantly reduces false positives compared to generic scanning tools. Every finding includes context about why it matters and how to verify it, so your security teams can focus on real issues — not noise.
Don't wait for a security breach. Use our website vulnerability scanner to look for security vulnerabilities and fix them before attackers find them.
