Security-header grade

A live check of the HTTP security-response headers retool.com sends, the same class of signal as securityheaders.com. Present headers score points; missing ones do not.

HEADER HYGIENE
E
20/100
✖Content-Security-Policy
✔Strict-Transport-Security (HSTS)
✖X-Content-Type-Options
✖X-Frame-Options
✖Referrer-Policy
✖Permissions-Policy
What this is, and is not. This grade reflects only the publicly observable HTTP response headers of retool.com, measured automatically. It is a hygiene indicator, one signal among many. It is not a security audit, not a penetration test, and says nothing about Retool's internal systems, code or data handling. Many secure sites score below A because headers like Content-Security-Policy are commonly omitted.

  • Internal CRUD tools
