Top issues to fix
6 issues found · 1 high priority
Missing Strict-Transport-Security header

Missing X-Frame-Options header
SecurityAdd X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
6 cookies without Secure/HttpOnly flags
SecuritySet Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.
robots.txt not found
SEOPublish /robots.txt with a Sitemap: directive to guide crawlers.
sitemap.xml not found
SEOPublish an XML sitemap and reference it from robots.txt to speed up page discovery.
20 broken links on the page
