Dionach

Dionach by Nomios has over 25 years of expertise in information security, supporting organisations in building resilience against ever‑evolving cyber threats. Certified to ISO 27001, PCI QSA, CESG CHECK, and CREST standards, we provide trusted services across Penetration Testing, Red Team Assessments, PCI DSS and ISO 27001 Auditing & Consultancy, Incident Response, and AI Governance.

Our dedicated Research & Development team continually investigates emerging risks, working closely with leading vendors and clients to share insights and strengthen defences. We believe effective cyber risk management requires more than technical controls. It demands a robust Information Security Management System, reinforced by regular, high‑quality security testing and forward‑looking governance frameworks.

With the addition of our AI Governance service, we help organisations adopt AI responsibly, ensuring compliance, transparency, and ethical risk management as part of a holistic security strategy.
