Bank-level security to protect your business and your customers. We take security seriously so you don't have to worry.

Voice & Telephony Security
Your AI phone line, protected end to end
Verified Caller ID
Carrier-level caller authentication (STIR/SHAKEN) screens inbound calls and flags spoofed or unverified numbers before they reach your business.
Spam & Robocall Blocking
Automated robocall and spam filtering with real-time abuse-pattern detection and blocklists that learn across the platform.
Caller Verification
One-time passcodes are delivered only to the caller's own registered line before any sensitive action — recognizing a number never replaces verifying the person.
Spoken Card Protection
Card numbers spoken on a call are automatically masked from transcripts, logs, and records in real time, so raw card data is never stored.
Abuse & Cost Controls
Per-account usage, duration, and rate limits stop call flooding, runaway AI spend, and automated abuse before it impacts your account.
Encrypted Recordings
Call recordings are encrypted at rest, with consent captured before any recording begins.
Incident Response
Prepared for anything
We maintain a comprehensive incident response plan with 24/7 security team coverage. In the unlikely event of a security incident:
