Computer Network Defence Ltd (CND) Tech Stack

UK cyber consultancy with SOC operations, penetration testing, and threat intelligence

Computer and Network Security Corsham, Wiltshire 11–50 employees Founded 2004 Privately Held

CND is a 20-year-old UK-based cyber security consultancy built on a foundation of Security Operations Centre design and operation. Their tech stack reflects dual operational modes: SIEM-heavy (Elasticsearch, Splunk, LogRhythm, ArcSight) for threat detection and response, paired with infrastructure-as-code tooling (Terraform, Ansible, AWS/Azure/GCP) for secure deployment. Current hiring is security-dominant (8 roles) with a strong engineering push (7 roles), suggesting they're scaling both threat operations and product development—likely tied to their Radar threat-intelligence platform and expanding consultancy delivery.
