DomainGrade vs Hardenize

Hardenize (now part of Red Sift) is a security researcher's protocol monitor; DomainGrade turns the same ground into one grade with a fix attached to every finding.

Hardenize earned its reputation on protocol depth: TLS configuration, DNSSEC, DANE, CT-log monitoring — inspected thoroughly and reported precisely. Since its acquisition it lives inside Red Sift's enterprise platform.

DomainGrade covers the same ground a working business actually acts on — email authentication, certificates, headers, DNS, reputation — and optimises for a different reader: the owner or MSP who needs one grade a client understands and a paste-ready fix for every gap, at a flat, published price.

Where Hardenize is the better fit

The honest verdict

For a security team living in protocol internals, Hardenize's depth is the point. For everyone who needs the same risks graded, explained and fixed without a security team — and shown to clients under your own brand — DomainGrade was built for exactly that.

Common questions

Is DomainGrade less thorough?
It's differently scoped: 34 checks across five areas, chosen because they're the ones with a clear fix and a real consequence. We publish what every check looks at, and the scan output shows its evidence.
Does DomainGrade check DNSSEC?
DNS hygiene checks cover delegation, CAA and related records; full DNSSEC/DANE validation is deliberately out of scope today — if that's a requirement, a protocol-depth tool fits better.
What does white-label mean here?
On the Agency plan the report carries your logo, accent colour and footer — as a shareable page and a scheduled PDF your clients receive from your address.

The comparison that actually matters: your domain, graded.

All 34 checks, one grade, and the exact fix for anything that isn’t right — in about twenty seconds, no signup.
