Business challenge

The client was migrating their product from Python to Golang to improve performance and scalability. During this transition, they needed a new Windows-based service that could integrate seamlessly with the existing system while ensuring data integrity and high security standards.

Due to limited in-house C# and Windows expertise, the client required a senior engineer to take ownership of a critical component and deliver a secure, production-ready solution.

Product overview

An anti-ransomware solution that takes a smarter approach: instead of protecting user endpoints, it focuses on safeguarding the data itself.

The moment ransomware begins encryption, the attack is stopped instantly. No manual action or software installation on user devices required:

  • Real-time monitoring of file servers and data storage to detect suspicious encryption activity;
  • Instant automated response that blocks ransomware-like behavior before damage is done;
  • No endpoint installation - works independently on user devices;
  • No signature scanning - instead of chasing malware, it stops unauthorized encryption right away.
