Founded in 2012 and headquartered in London, UK, CYJAX is a leading cybersecurity firm specialising in threat intelligence and digital risk monitoring. CYJAX aggregates data from across the internet, social media, and darknet marketplaces to deliver actionable insights to enterprises and government entities.
Given their role in helping organisations anticipate and defend against sophisticated cyber threats, CYJAX requires an IT environment that is secure, resilient, and scalable by design.
The Challenge: Modernising for Security and Scale
CYJAX needed to migrate its aging on-premises infrastructure to AWS to support future growth and deliver services with greater agility. However, earlier attempts had been slowed by delays and technical challenges. For an organisation working in the cybersecurity space, this migration couldn’t just be a “lift and shift” - it needed to be secure, automated, and built for resilience from day one.
The Cloud Bridge Approach: Building Security and Resilience into the Foundation
AWS recommended Cloud Bridge as a trusted partner. From the outset, we recognised CYJAX’s requirements: a secure, modern cloud foundation that eliminated legacy pain points and empowered their teams.
Our solution was a phased, ground-up migration, underpinned by Infrastructure as Code (IaC) and a security-first mindset:
- Infrastructure as Code (Terraform) → repeatable, automated deployments with full version control.
- Serverless Compute (AWS ECS Fargate) → scalable, patch-free containerised workloads across multiple Availability Zones.
- Reliable Databases (Amazon RDS) → managed, multi-AZ database services.
- Security by Design → a multi-account Landing Zone for governance and isolation, plus a hub-and-spoke networking model with AWS Transit Gateway and Network Firewall for centralised inspection of all traffic.
- CI/CD Automation (GitLab) → pipelines enabling faster, consistent deployments with auditable history.
- Unified Observability (Amazon CloudWatch) → replacing legacy monitoring tools with actionable, low-noise visibility into systems and applications.
Execution was guided by a detailed migration runbook, covering everything from Terraform deployments to DNS cutover and staging validations. This disciplined approach ensured predictability, transparency, and control at every step.
The Results: A Cloud Environment Built for the Future
CYJAX’s new AWS environment is not only modern and scalable, but also aligned with their cybersecurity mission:
- Scalable & Resilient → Multi-AZ architecture with automated scaling ensures continuous availability.
- Secure by Default → Multi-account separation and firewall-inspected networking enforce strong governance and compliance.
- Operational Clarity → CloudWatch eliminated monitoring fatigue from noisy legacy logs. CYJAX can now spot heavy resource usage early and take proactive action, improving incident response and operational insight.
- Engineering Agility → GitLab CI/CD pipelines have greatly shortened deployment times, enabling new services to be provisioned far faster than the manual server setup process.
- Cost Efficiency → With infrastructure now rightsized, over-provisioning has been eliminated, significantly reducing ongoing infrastructure spend.
Cloud Bridge delivered exactly what we needed: a secure, modern cloud environment that supports our mission.
We’ve gained scalability, reduced costs, and most importantly, confidence in the resilience of our systems.
