Hey everyone, I'm Nicky, CEO of ScreenStop.

We're building Screen DLP — a new security category that traditional
DLP completely misses.

records, trading positions, or source code and photographs it with
their phone. The data never moves digitally — so network monitoring,
clipboard controls, and file restrictions are all blind to it.

What we built: on-device AI running on the endpoint's webcam that
detects when a phone is in capture position — and blurs the screen
before the photo is taken. No cloud, no data leaves the machine.

The hard engineering problem was false positive rate. Hands, coffee
cups, second monitors — all trigger naive models. Most of our work
went into making it not annoying to use.

Pre-seed, currently in pilots in healthcare and financial services.

Happy to discuss the detection model, the architecture, or the
category itself. What's your take — is this a gap you've seen in
your own security stack?
