About Security Headers
What are Security Headers?
Security headers are HTTP response headers that help protect your website and its users from various security threats. They provide an additional layer of security by instructing browsers on how to behave when handling your site's content.
Why are they important?
Properly configured security headers can help prevent cross-site scripting (XSS), clickjacking, MIME type sniffing, and other common web vulnerabilities. They are an essential part of a defense-in-depth security strategy.
