01Automatic call protection
Halo notices the meeting before you need to think about it.
It watches for active Zoom, Teams, and Meet windows, then begins checking visible faces locally. No meeting bot, browser extension, or copied link.
Launched on Product Hunt
Know who’s real on every video call.
Halo checks every visible face while you’re on Zoom, Teams, or Meet and warns you when a face looks synthetic—all on your device, while there’s still time to act.

Quiet when the call is real. Clear when it isn’t.
Halo is a desktop app—not a post-call report and not another person joining your meeting. It stays out of the way until the evidence changes.
02Evidence, not a single frame
Halo waits until the signal is strong enough to matter.
Poor lighting, compression, motion, and small faces can distort a frame. Halo gathers evidence over time before it changes a participant’s verdict or raises an alert.
03Local meeting history
After the call, the evidence stays with you—not with us.
Review participant verdicts and alerts from a local meeting history. Video frames are analyzed in memory and discarded; Halo never uploads or records your call.
How it works
Protection that starts with one install.
Halo lives beside your conferencing app and follows the call from first face to final verdict.
- 01
Install once
Download Halo to your Windows PC. It sits in the system tray next to your conferencing app — no plugins, no browser extensions.
- 02
Scans locally, live
As you talk, Halo analyzes every face in the video frame-by-frame on your device — roughly 4 times per second.
- 03
Flags in real time
If a face looks synthetic, Halo surfaces an alert during the call — in time to stop and verify.
Private by design
Your call never becomes our data.
No recording
Frames are checked in memory and discarded.
No cloud inference
Detection continues locally without a video upload.
No meeting bot
Halo reads the same rendered call window you see.
Where trust gets tested
The decision happens during the call—not after it.
Finance and treasury
~$25MConfirm who you’re wiring money to.
In the Arup fraud, a finance employee saw a familiar CFO and colleagues on a live call. Every face was synthetic. Halo is built for the moment before the transfer is approved.
HR and recruiting
1 in 4Confirm who you’re interviewing.
Gartner projects that one in four candidate profiles will be fake by 2028. Halo checks for synthetic and face-swapped candidates without sending the interview to a third party.

FAQ
The questions people ask before trusting Halo.
What is Halo?
Halo is an on-device deepfake detection application that monitors your video calls in real time and flags synthetic faces and faceswaps before they can fool you. It runs entirely on your Windows PC — no video frames ever leave your machine.
Does my call data get uploaded anywhere?
No. All detection runs locally on your device. Halo analyzes live frames in memory and discards them — it does not record, store, or transmit meeting video. Only detection verdicts and session metadata are kept, stored locally on your machine.
Which apps does Halo work with?
Halo works with 10+ meeting applications including Zoom, Microsoft Teams, Google Meet, WebEx, Skype, Slack huddles, GoTo Meeting, and others — both native desktop apps and browser-based meetings.
Will it slow down my calls or drain my battery?
Detection runs locally on your device, in parallel with your call. There is no network round-trip, so it adds no latency and minimal overhead.
How accurate is it, and what about false positives?
Halo gathers evidence across multiple frames and checks image quality before changing a participant’s verdict. Poor lighting, motion, or compression on a single frame is not enough to trigger an alert.
How is this different from my conferencing app's built-in security?
Platform-native features focus on access and meeting controls, not on detecting whether a participant's face is synthetic. Halo is purpose-built for real-time synthetic-media detection and works across every platform you use.
What devices does Halo support?
Halo runs on Windows 10/11, on both ARM64 and x86/x64 hardware. Minimum 4 GB RAM, ~1 GB disk space.
Available now for Windows
Stop guessing who’s on the call.
Install Halo once. Keep Zoom, Teams, and Meet. Get a clear warning when a visible face looks synthetic.
