You have a Content-Security-Policy, which is great — but it contains a wildcard source or allows 'unsafe-inline'/'unsafe-eval' in script-src. Those let injected scripts execute, which is most of what a CSP is meant to stop.
Your responses advertise the exact software you run (X-Powered-By: Next.js). It's not a hole by itself, but it hands attackers a shortcut: they can look up known vulnerabilities for that precise version instead of probing blindly.
The DMARC record on fratera.io uses p=none, which only reports spoofing — it doesn't stop it. Forged mail claiming to be from your domain is still delivered.
fratera.io is not protected by DNSSEC. DNSSEC signs your DNS records so resolvers can detect a forged answer — without it, an attacker who can poison DNS could point your domain at their own server without touching anything you control.
