About

A security company for digital communities.

We build layered defense and identity infrastructure for Telegram communities — free at the foundation, paid upgrades for advanced protection — and publish original security research that helps the whole community defend itself.

The name

Targa

Italian for shield / badge. The defensive front of the brand — what every member sees in every chat.

Praetorian

The Roman guard that both protected the emperor and struck for him. The dual meaning carries the defensive product and the future offensive-security research arm.

How we build

Principles we don't flex on.

Free at the foundation. The default tier is free forever — no caps, no card. Universal adoption is the goal, not revenue.
Every action explainable. A structured reason on every decision, at every tier. Opacity is the universal admin pain point.
The data compounds. A hosted, multi-tenant fleet learns once and protects everywhere — better and cheaper as it grows. The code is copyable; the corpus is not.
Closed source — we host it for you. Distributed as a managed bot and SaaS, not code to run. Zero ops for you; a clean upgrade path for us.
Research is public. Original AI-threat research, published freely — and fed straight back into detection.

Anti-spam today. AI security for digital communities tomorrow.
