**About the company:** Cyberhaven is a fast-growing startup, trusted by some of the most well-known investors of Silicon Valley. The company was set up in 2016 and raised over $15M from investors. Our product is used by cool companies like Zoom, Motorola, Western Digital, by the U.S. Department of Defense’s DARPA agency (the one that created the Internet!), and others. 

**The product:** We built a dynamic data-tracing platform which enables all data flows to be tracked across entire companies. Data flow history can be  used to detect exfiltration of critical and sensitive data in real-time. 

**The technical stack:** No legacy code, the product was designed from scratch a few years ago using the most up-to-date technologies. The product uses a modern architecture, a microservices-based backend with strict performance and scalability requirements, deep integration with Windows and macOS, and a diverse set of cloud APIs for integration with SaaS applications.

On Windows - C++ in the driver and C# user-space system, using a combination of APIs (ETW, Win32, UIA, etc.).

On MacOS - Swift and Endpoint Security Framework, and a lot of inter-process communication with messages.
