Spam calls, screened before they ring

For identity protection programs

A benefit your members will notice every day

Add Call Shield to your identity protection program as a premium benefit or upsell. Scam calls are how most identity fraud starts, and this one shows its value on every spam call it stops.

Your brand

Your name in the greeting, your voice, your numbers, your texts.

Upsell-ready

Offer it as a paid tier or a retention perk, with per-member usage you can report on.

No app

Members sign up from a link and turn on forwarding in about three minutes.

How it works

Members sign up in a minute. From your invite link or your API. They get their own screening number and choose whether to get summaries by text.
Unknown callers go to the AI. Calls they miss from numbers that aren't in their contacts are forwarded to it. Contacts ring through as usual.
The AI asks who's calling and why. It spots spam, scams and robocalls from the conversation, not from a blocklist that spammers dodge by switching numbers.
Spam is ended silently. Real calls reach them. They get a summary and transcript, and urgent callers are put through to them.
