Is your encryption ready for the Quantum Era?
Adversaries are recording encrypted traffic today to decrypt the day quantum computers arrive. CipherGap grades a host’s post-quantum readiness in seconds — free.
CipherGap performs non-invasive TLS configuration checks only — no exploitation, authentication attempts, brute force, or denial-of-service testing.
“Harvest now, decrypt later”
The data you encrypt with today’s RSA and elliptic-curve cryptography isn’t safe forever. Well-resourced adversaries are already capturing encrypted traffic and storing it — betting that a quantum computer will let them decrypt it within the decade.
Anything with a long shelf life — health records, financials, IP, state secrets — is a target right now. The only defense is migrating to post-quantum cryptography before that day comes.
Today
Encrypted traffic is intercepted and archived at scale.
Until then
It looks safe. Your classical TLS holds — for now.
Q-Day
A quantum computer breaks RSA/ECC. The archive is decrypted.
2035
NIST's target to remove quantum-vulnerable RSA & ECC — high-risk systems sooner
Today
when “harvest now, decrypt later” capture already happens

How it works
From a single scan to continuous monitoring.
Scan
Enter a domain you own or are authorized to assess. We run live TLS handshakes — including a hybrid post-quantum probe — and grade the host A–F.
Monitor
Create an account to save hosts to a dashboard. Paid plans add scheduled re-scans on a daily or weekly cadence.
Get alerted
Get an email the moment a monitored host's grade drops — so you can act before adversaries do.
Know where you stand in seconds.
Run a free scan, then let CipherGap watch your hosts and alert you the moment your quantum readiness slips.
