The Readiness Scan negotiates a real handshake with your domain, reads its ciphers and signatures, and hands back a single letter — A through F — for how exposed you are to Harvest Now, Decrypt Later. Free to run. No signup. No app changes.
We weight key exchange, certificate signatures, stored-data horizon and protocol hygiene into one honest grade.

The free scan grades your front door. The deep scan walks the whole house — and hands your team a remediation order.
Every endpoint, cipher suite and certificate chain across your domains and subdomains.
Tunnels and remote-access gateways — the long-lived sessions adversaries love to record.
SMTP/TLS posture, where decades of correspondence travels in the clear-ish.
Storage and backup encryption, weighted by how long that data must stay secret.
Where keys live, how they rotate, and whether your stack can swap algorithms at all.
A ranked, plain-language to-do list — what to fix first for the biggest exposure cut.
Before Secuur graded a single customer, we ran the deep scan on ourselves — and didn't like the D we got. So we migrated every endpoint, API and internal link to hybrid post-quantum encryption, then wrote down exactly how. Your migration isn't an experiment. It's a path we've already walked.
A one-time deep scan with the full seven-layer teardown, your remediation order, and a shareable PDF your board will actually read. Pay once. No subscription.
A low grade routes straight to the right fix — self-serve for smaller teams, a guided plan for regulated ones. Never a dead end.
