Zabcore · Independent privacy studio

Two tools. One job:
protecting what your team can't afford to lose.

Zabcore builds small, focused, privacy-first tools. Each one solves a real problem completely — without bloat, without collecting what we don't need, and without pretending to be something it isn't.

PayGuard · For business

Stop invoice fraud before money moves.

A fake invoice. A swapped bank account. A vendor email that didn't come from your vendor. PayGuard connects to Microsoft 365 and QuickBooks, reads every invoice as it arrives, and flags risk before payment.

  • Detects vendor impersonation, bank account swaps, and business email compromise
  • Connects in two minutes — read-only Microsoft 365 + QuickBooks
  • Never moves money. Detection only. Your team decides every action.

How we build

Three principles. No compromise.

/ 01

Privacy is engineering, not marketing.

We design products so the sensitive thing never leaves your device or your control. Not "encrypted in transit." Not "stored securely." Not present in the first place.

/ 02

Honest about what we do.

No "AI-powered" when it's regex. No "bank-grade" when it's standard TLS. No certifications we don't hold. The product does what we say, and nothing it doesn't.

/ 03

Small tools, sharp edges.

We don't build platforms. We build narrow tools that do one thing exceptionally well, ship them, and move on. Less surface area means fewer ways to fail you.

The studio

Built by a small team, for people who need fewer surprises.

Zabcore isn't a startup chasing a unicorn exit. It's a studio. We build privacy-first tools the way we'd want them built if they were running on our own systems — because half the time, they are.

More products will come. They will be small. They will be focused. And they will not collect data we don't need to do the job.
