Explore expert security tutorials, diagnostic tools, automated scanners, and step-by-step guides for Application Security.
Free online checkers, analyzers, and calculators for application security.
Review whether your application adheres to defensive software security best practices across authentication, authorization, secure SDLC, APIs, secrets, dependencies, testing, logging, and CI/CD pipelines.
Generate a comprehensive, customizable Application Security Policy covering secure SDLC, authentication, input validation, cryptography, secrets management, API security, vulnerability management, and incident response.
Check your domain's CAA DNS records and see which certificate authorities are authorized to issue normal or wildcard certificates. Analyze issue, issuewild, iodef, and CAA flags for free.
Check a website's cookies for Secure, HttpOnly, SameSite, Domain, Path and expiration settings. Identify potentially risky cookie configurations and get clear security recommendations.
Check and analyze a website's Content Security Policy. Detect CSP headers, Report-Only policies, unsafe directives, wildcard sources, framing controls, nonces, hashes, and common configuration issues.
Check whether a website redirects HTTP to HTTPS, inspect redirect status codes, follow the redirect chain safely, detect loops or HTTPS downgrades, and review the final destination.
Review, track, and document application security controls interactively with OWASP ASVS and NIST SSDF verification baselines, gap analysis, and multi-format export.
Audit your web applications against OWASP Top 10 vulnerabilities: Broken Access Control, Cryptographic Failures, Injection, Insecure Design, Security Misconfiguration, and SSRF.
Assess the implementation status and operational effectiveness of technical and administrative security controls across NIST CSF, ISO 27001, and CIS benchmarks.
Check a website's HTTP security headers including CSP, HSTS, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, framing protections, and other supported headers.
Generate standardized security.txt files and vulnerability disclosure policies conforming to RFC 9116 for your /.well-known/security.txt deployment.
Check which TLS versions a website supports. Test TLS 1.0, 1.1, 1.2, and 1.3 availability and identify legacy TLS protocol support with SafeNetworkHub.
Calculate Common Vulnerability Scoring System (CVSS v3.1) base scores: Attack Vector, Attack Complexity, Privileges Required, Scope, and Confidentiality/Integrity/Availability impact metrics.
Review and verify defensive website security controls across HTTPS, security headers, authentication, cookies, dependencies, backups, and configurations.
Enter any public URL to audit HTTP security headers, SSL certificates, DNS hygiene, and security posture in seconds.
