TwinStream Tech Stack

Cross-domain security solutions for defence and critical infrastructure

Computer and Network Security Cheltenham 51–200 employees Founded 2018 Privately Held

TwinStream builds cross-domain security architecture for defence and government organisations, with a heavy infrastructure-as-code footprint (Terraform, Ansible, Chef) and container orchestration across Kubernetes, OpenShift, and Docker Swarm. The stack signals mature DevOps discipline paired with multi-cloud deployment (AWS, Azure, GCP). Current hiring is senior-weighted (4 of 6 open roles) and engineering-only, suggesting they're scaling delivery capability to handle complex, high-assurance projects rather than expanding into new functions.
