We solve security challenges in complex, large-scale systems end-to-end—from R&D to professional services, from open-source developer tools to bespoke solutions, focusing on practical risks in real-world scenarios. We protect tomorrow’s critical systems by helping build them securely today without compromises and security band-aids.

Quick facts about us:

⦿ We operate in domains where security and risk matters—defense, energy, finance, healthcare, and GovTech, building security for large, distributed systems and products where failure isn't an option. We bring an expert team to operate across technological stacks—from hardware security and mobile apps to clouds and distributed SCADA systems.

⦿ We combine security and tech expertise in cryptography, hardware security, machine learning, platform security, security engineering, SSDLC, organisational security, software engineering, infrastructure engineering, military communications security. We work closely with teams that build and maintain complex systems, embedding into their process and delivering security tailored and adapted to target environments.

⦿ Cryptography engineering is our passion. We design, implement, audit cryptography-based components, protocols, and systems. Our experienced cryptographers work with traditional cryptography & novel schemes that deviate from typical use cases. We excel at difficult tasks.
