Authentication, licensing, and protection for desktop software.
Accounts, licensing, obfuscation, and server-side protection for Windows and Linux applications. Use the built-in authentication, or proxy your own endpoints with rate limiting and DDoS protection.
Why this exists
Everything on the market today falls into one of these holes. Click any row to go deeper.
The old tried and true, but with modern emulation and writeups, the obscurity has faded and these products are simply outdated.
Works. Not an option unless you’re shipping a AAA game.
Trivially emulated, run by kids with no experience or concept of security, and coded entirely by AI. Every claim they make is a blatant lie.
Windows-only or Linux-only. Pick one.
What Nexyn provides
Click any feature to go deeper.
Authentication & users
User accounts, sessions, and token management. Use Nexyn’s hosted auth, or route requests through your own backend.
Licensing
License keys, subscriptions, trials, and hardware-bound licenses, with reseller support built in.
Obfuscation
A full obfuscation system with dependency bundling, including DLLs. This could be it's own product, but we're nice :)
Secure payload delivery
Encrypted payload download and execution. Download works across all supported platforms; execution that prevents dumping is locked to DLLs on Windows for now.
Compromise detection
Trained models track environment data from program start, through login and payload download, to detect compromised environments and automatically flag or ban users. Windows only for now.
Auth proxy
Place Nexyn in front of your own endpoints for rate limiting, geographic rules, and DDoS protection.
Windows and Linux, from one backend.
Nexyn links into your compiled binary, so the language you write in doesn’t matter. Anything that compiles to a supported format works. Windows x64 (64-bit PE) is supported today; Linux x64 (64-bit ELF) is in active development.
