Steps to improve termius.com's security grade, ranked by impact.

1
Enable DNSSEC on your domain
Impact: 1–3 Days (Depends On Registrar)
MEDIUM
Without DNSSEC, DNS responses for termius.com can be spoofed, potentially redirecting users to malicious sites. This requires coordination with your domain registrar to publish DS records.
Compliance impact
NIST 800-53SC-20
Secure name/address resolution service
How to fix this
1
Check if your DNS provider supports DNSSEC (Cloudflare, Route53, etc.)
2
Enable DNSSEC signing in your DNS provider dashboard
3
Add the DS record to your registrar for .com TLD
4
Verify: dig +dnssec termius.com
2
Add optional security headers (CSP, X-Frame-Options)
Impact: < 1 Hour
LOW
termius.com has most security headers configured. Missing: CSP, X-Frame-Options. These are best-practice additions that reduce the attack surface for client-side vulnerabilities.
How to fix this
1
Add Content-Security-Policy header (start with report-only to avoid breakage)
2
Add: X-Frame-Options: DENY (or SAMEORIGIN if you use iframes)
3
Verify with: curl -sI https://termius.com | grep -iE 'content-security|x-frame|x-content|referrer|permissions'
