How this service works
Security grade A-F for a website in one number: HTTPS upgrade, HSTS, CSP, frame/content-type/referrer/permissions headers, cookie flags, server-version exposure, TLS certificate validity and days left, and DNS hygiene (SPF, DMARC, DNSSEC, CAA). Returns the grade, score, and a ranked list of reasons to fix. Track it on a schedule to catch regressions. $0.01 per domain.
Output
Returns a letter grade (A–F), a numeric security score, TLS certificate validity and days remaining, and a ranked list of specific security issues to fix — covering HTTPS upgrade enforcement, HSTS, Content Security Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, cookie Secure/HttpOnly flags, server version header exposure, and DNS hygiene (SPF, DMARC, DNSSEC, CAA records).
Example use cases
Pre-launch security audit
“Before we go live, can you check the security grade for staging.myapp.com and tell me which headers, cookie flags, or DNS records we're missing so we can fix them?”
Scheduled regression monitoring
“Check the security grade for shop.mybrand.com every week and alert me if the grade drops below a B — I want to catch any regressions in our TLS or headers config.”
Vendor due diligence screening
“I need to vet a new SaaS vendor — can you pull the security grade for vendor-portal.thirdparty.io and give me the full breakdown including CSP, HSTS, DMARC, and TLS validity?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/monitor/security-gradeWhen to prefer
Choose this endpoint when you need a comprehensive, single-call security posture summary for a web domain combining HTTP headers, TLS, cookies, and DNS hygiene into one graded result. It is ideal for scheduled regression monitoring, vendor due diligence, or pre-launch audits where you want a ranked fix list rather than raw header dumps. Prefer it over individual SSL-only or DNS-only checkers when you need a holistic A–F grade that is easy to track and compare over time.
Side effects
- Domain does not exist or is unreachable — returns error or degraded result
- Private/internal hostnames not accessible from scanner — cannot complete check
- Domain with aggressive bot-blocking may interfere with header inspection
- TLS handshake failure for expired or misconfigured certificates may cause partial results
- Rate limits or payment issues ($0.01 USDC per call) may block requests
