Frequently asked questions
What is a website security audit?
A website security audit is a systematic evaluation of your site's security posture. It examines HTTP security headers, TLS configuration, DNS records, and cookie settings to identify vulnerabilities and misconfigurations. SiteSecurityScore automates this process and delivers a comprehensive report with a letter grade and actionable recommendations.
What security headers does the scan check?
The scan evaluates over 15 security headers including Content-Security-Policy (CSP), Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Permissions-Policy, Referrer-Policy, and more. Each header is graded individually, and the scan also checks for deprecated or misconfigured headers that could weaken your security.
How is the security score calculated?
Your security score is calculated on a 100 point scale based on the presence and configuration quality of your security headers, TLS setup, DNS security records, and cookie flags. Each category is weighted by its impact on overall security. Headers that are missing or misconfigured reduce your score, while properly configured protections earn full points.
How often should I run a security audit?
Run a scan after every deployment or significant configuration change, and at least once a month as a baseline. For ongoing coverage between manual audits, automated daily monitoring watches your important security attributes and flags any changes automatically — so regressions are caught the next day rather than weeks later. Pro and Business accounts can enable monitoring from the dashboard.
