Built for Windows. Built to last.

Every product ships with a kernel-mode driver or deep system integration — real enforcement, not surface-level wrappers.

Real protection. No gimmicks.

Kernel-Level Enforcement

Our products use Windows minifilter drivers — the same technology used by antivirus software. Protection is enforced by the OS kernel, not by hiding files or hoping users don't look.

No Subscriptions Required

Most products offer lifetime licenses. Pay once, use forever. Annual options exist for businesses that need fleet management and central administration.

Lightweight & Native

Built in C++ and C# with WPF — no Electron, no web wrappers. Minimal memory footprint, instant startup, native Windows look and feel.

41 Languages

Full localization across 41 languages. Privacy-sensitive payment flows are localized too, so every user gets a native experience regardless of region.

Built by a Developer, Not a Committee

Small team, fast iteration, direct support. When you report a bug or request a feature, it goes straight to the people writing the code.

Fleet Management

Business tiers include LAN fleet management for deploying rules, policies, and monitoring across multiple machines from a single console.
