Network and Cybersecurity Engineering
Secure network design, identity, TLS, container and Kubernetes security, built into infrastructure rather than bolted on.
Overview
Security is mostly a property of how systems are built and configured. We design networks, identity and workload controls so that the secure configuration is the default one.
Our work covers cloud network segmentation, firewall and access-control integration, identity and access management, certificate management, API security and the hardening of containers and Kubernetes clusters.
We are direct about limits. No configuration makes a system immune to attack, and we do not certify compliance. What we provide is careful engineering, clear documentation and reviews that tell you where the real risks are.
Problems we address
- Flat networks where any workload can reach any other
- Shared administrator accounts and long-lived credentials
- Containers running as root with broad permissions
- APIs exposed without consistent authentication or rate limits
- Vulnerability scan results that pile up without a triage process
What we deliver
- Network architecture and segmentation
- Hub-and-spoke or zoned designs with controlled ingress, egress and private endpoints.
- Identity and access management
- Single sign-on, role design, workload identity and least-privilege access reviews.
- TLS and certificate management
- Automated issuance and renewal, mutual TLS between services and key handling.
- Container and Kubernetes security
- Non-root images, security contexts, network policies, admission control and secrets handling.
- API security
- Authentication, authorisation, input validation, throttling and gateway policy.
- Security monitoring integration
- Routing the right signals to your monitoring or SIEM tooling with useful context.
- Vulnerability management workflow
- Scanning in pipelines, triage rules and tracked remediation.
- Architecture security reviews
- Structured reviews of designs and existing environments with prioritised findings.

Example use cases
Illustrations of the kind of work this covers.
- Segmenting a cloud network and removing unnecessary public endpoints
- Introducing single sign-on and role-based access across internal tools
- Hardening a Kubernetes cluster ahead of a client security review
- Adding image scanning and policy gates to an existing pipeline

Delivery approach
Discover
Understand the business goal, the systems in place and the constraints: budget, compliance, skills and timelines.
Design
Agree an architecture and delivery plan, with the trade-offs written down and the risks named early.
Build
Deliver in small, reviewed increments with automated tests, infrastructure as code and regular demonstrations.
Launch
Release through pipelines with monitoring, rollback paths and runbooks in place before go-live.
Operate and improve
Run, measure and refine, or hand over fully documented to your own team.
