No Content-Security-Policy, so no defence in depth against cross-site scripting
−

−
No X-Content-Type-Options, so MIME sniffing is not disabled
−
No X-Frame-Options and no CSP frame-ancestors, so clickjacking is possible
−
No Referrer-Policy, so full URLs may leak to third parties
−
No Permissions-Policy, so powerful browser features are not restricted

No Cross-Origin-Opener-Policy
−
No Cross-Origin-Resource-Policy

No server-version or X-Powered-By disclosure
This is one narrow, automated check of the HTTP response headers on the vendor's own website. It says nothing about how the product itself is built, how it stores your data, or whether it has ever been audited. A good grade here is a small signal that somebody was paying attention.
