Adamant is a cyber and information security service provider. Born from our passion for hacking and problem solving, and the continuous growth of the need for cyber security services on all types of business, we cover a broad spectrum of services, such as penetration testing, red teaming, security and privacy audit, and forensic analysis.

Who we are

Born to develop and deliver high-quality cyber security services to organizations, we strive to move away from “checklist audits”, to perform in-depth assessments and uncover hard-to-find complex problems to, finally, propose solutions. We believe that this cannot be achieved without a great commitment, constant training, and investigation. For the same reason, Adamant also promotes research, and frequent participation in cyber security-related events and competitions.
