Halo catches deepfakes on device.
On your device, in real time. Halo flags synthetic faces and faceswaps live on every call — before they cost you a wire transfer or a bad hire.
The new attack surface
Your calls just became
a place to get attacked.
Real-time face-swaps are good enough to pass as a colleague on a live video call. Email filters and login checks never see them — the fraud happens in the conversation itself.
FOR FINANCE & TREASURY
The voice approving the wire
might not be your CFO.
- Flags synthetic faces and faceswaps live, before the transfer is approved.
- Protects treasury, AP, and exec assistants on every Zoom, Teams, Meet, WebEx, and Slack call.
- Leaves an on-device audit trail for fraud and compliance review.
lost in a single deepfake video call (Arup, 2024)
In 2024, a finance employee at engineering firm Arup joined a video call with what looked and sounded like their CFO and colleagues — every face on the call was a deepfake. They authorized 15 transfers totaling ~$25M. The call looked completely normal. That's the new attack: real-time synthetic executives on routine approval calls.
Why on-device
Cloud detection can't keep up with a live call.
Private by design
Video frames are analyzed in memory and discarded — nothing is recorded, stored, or transmitted. No cloud upload means no new honeypot of sensitive calls, and a far simpler path through legal, IT, and GDPR review.
Real-time, no round-trip
Detection happens in the same moment as the call. There's no upload, queue, and download cycle — so a verdict lands while the call is still happening, not after the money's gone.
Smaller attack surface
Cloud detectors add APIs, uploads, and third-party storage — each one a target. Halo keeps everything on the device: no network calls during detection, no frames in transit, no external servers holding your call data. Fewer moving parts, fewer ways in.
How it works
Protection that lives on the call
Install once
Download Halo to your Windows PC. It sits in the system tray next to your conferencing app — no plugins, no browser extensions.
Scans locally, live
As you talk, Halo analyzes every face in the video frame-by-frame on your device — roughly 4 times per second.
Flags in real time
If a face looks synthetic, Halo surfaces an alert during the call — in time to stop and verify.
