CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://www.5sterrenspecialist.nl/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.

The browser will also send this cookie over plain http://, where it can be captured.
What to do
Add `Secure` to the cookie.

Receivers are asked to report spoofing but not to block it. This is the right first step, and the wrong place to stop.
What to do
Once reports look clean, move to p=quarantine, then p=reject.

Without clientTransferProhibited, a compromised registrar account can move the domain to another registrar in days, with no second step.
What to do
Enable the transfer lock (and registrar lock, if offered) in the registrar control panel.
asset: 5sterrenspecialist.nl
Without HttpOnly, any injected script can read and exfiltrate this cookie.
What to do
Add `HttpOnly` unless client-side code genuinely needs to read it.
asset: https://www.5sterrenspecialist.nl/
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: 5sterrenspecialist.nl
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
