Stop identity breaches with a rational approach.
Stolen identities are the entry point for most breaches. SDI removes that entry point: you prove who you are with cryptographic math, so no passwords, codes, tokens, or biometrics are ever transmitted or stored. Nothing to steal, phish, or replay.
No shared secrets—because a shared secret is not a secret.
277days, on average, to detect and contain a breach. Stolen credentials, phishing, and compromised business email push that number higher. SDI prevents the identity breach before it happens.

Prevention that strengthens detection
Most breaches start with a stolen identity. SDI takes that off the table.
Monitor, detect, and respond are essential — but security teams are buried under alerts from stolen credentials, phishing, and account takeover. SDI eliminates identity-based attacks at the source, so those teams can focus their resources on the sophisticated threats that actually need them.

Detection teams sort real attacks out of a flood of identity-based noise.
- MonitorWatch traffic and logs
- DetectSurface real intrusions
- RespondAct on genuine threats
Resources stretched thin across attacks that never should have reached them.
With SDI
Identity-based attacks are gone before they generate an alert.
Your team's time and tools go to the sophisticated threats that truly demand them.
How SDI works
Proof without exposure, in four steps
SDI uses public-key cryptography, the same math that secures the world's most sensitive systems, to confirm identity without ever sending anything an attacker could capture.
- Step 1
Create your keys
Your device generates a private key that never leaves it, paired with a public key it can share freely.
- Step 2
Register the public key
The service stores only your public key. There is no password database and no shared secret to breach.
- Step 3
Get a one-time challenge
At login, the service sends a random challenge that is valid exactly once, so it can never be reused.
- Step 4
Prove it mathematically
Your device signs the challenge with the private key. The service verifies it and lets you in — nothing secret ever crossed the wire.
How SDI compares
Every other method still has a secret to lose
