During the digital landscape of 2026, site safety and security is no longer a high-end-- it is a baseline demand. While firewall softwares and SSL certificates prevail, among the most effective yet frequently overlooked layers of defense lies in your server's HTTP action headers. Using a safety header checker like SiteSecurityScore allows you to identify covert vulnerabilities that might leave your customers and your credibility in jeopardy.
A security headers scanner does greater than simply checklist technical information; it gives a roadmap to protecting your website against contemporary threats like Cross-Site Scripting (XSS), Clickjacking, and procedure downgrades.
