The CyResLab team has expertise in various aspects of information security - cryptology, secure architectures, secure software development, threat modelling and others. Our laboratory has real-world experience in heterogeneous technologies and complex IT systems security, including, but not limited to: Endpoint security (Linux, Android, Windows), Server security (Linux), Application Security (PHP, .NET, JavaScript), Cryptography (Homomorphic encryption, Searchable encryption, etc.) and many others.

We strongly believe in a holistic approach to security, both in the cyber and physical domain.
