How It Works
Three steps from URL to a complete security report with actionable fix instructions for every finding.
Paste Your URL
One URL is all it takes. No agents, no plugins, no access tokens. Works on any public-facing site.
We Run 62 Checks
We check TLS, headers, DNS, cookies, CORS, and exposed endpoints — 62 checks across all major security categories.
Review Findings. Enable Monitoring.
Get exact fix instructions for each issue, then enable continuous monitoring to be alerted when something regresses.
62 Automated Checks. Exact Fix Instructions.
One scan covers TLS, security headers, DNS, cookies, CORS, and content — each finding paired with specific steps to resolve it.
Continuous Monitoring
A fix today can break tomorrow. Daily or weekly automated scans catch regressions as soon as they appear, with email or Slack alerts.
TLS/HTTPS Security
Checks certificate validity, cipher strength, protocol version, OCSP stapling, and redirect behavior — with specific remediation for each finding.
Security Headers
Reviews all major security headers — CSP, HSTS, X-Frame-Options, Permissions-Policy, and more — with the exact HTTP directives to add.
Email Security
Validates SPF, DKIM, and DMARC records against current standards so your domain's email configuration is correctly authenticated.
CORS & Cookie Security
Validates CORS policies and cookie attributes (HttpOnly, Secure, SameSite) against current best practices, with steps to tighten each one.
Network Exposure
Identifies open ports and reachable admin paths from the public internet, with details on each exposed service.
Compliance Mapping
Map your scan results to SOC 2, ISO 27001, PCI DSS, HIPAA, GDPR, and NIS2 frameworks. Export a PDF audit report ready to share with customers or auditors.

The Checks That Matter Most
The most commonly misconfigured security controls, each with detection logic and step-by-step remediation instructions.
Content Security Policy (CSP)
Prevent XSS and code injection attacks
HSTS enabled
Force HTTPS and stop downgrade attacks
OCSP Stapling
Speed up TLS with cached certificate status

Ensure modern TLS 1.2+ encryption
SPF Record
Protect your domain from email spoofing
DMARC Policy
Enforce email authentication policies
Subdomain Takeover
Detect dangling DNS records attackers can claim
Vulnerable JavaScript Libraries
Find known CVEs in frontend dependencies
Set-Cookie headers
Secure session cookies against theft
Certificate Expiry
Catch expiring SSL certificates early
Access-Control-Allow-Origin
Verify CORS policy isn't too permissive
DKIM Record
Validate email signing configuration
