We build, secure and run IT infrastructure.

Lean Security Help designs, operates and defends the systems businesses depend on. One team for the application and the infrastructure underneath it.

What we do

Applications built to fit how you work, and to run on infrastructure we can operate too.

Networks designed for uptime, with the routing, segmentation and monitoring to keep them that way.

Day-to-day operation, patching and capacity planning across virtualised and private-cloud platforms.

Metrics, logs and alerting, so problems surface before your users report them.

Hardening, vulnerability management, audits and incident response.

Build pipelines, infrastructure as code and deployments that repeat exactly.

Architecture and planning for private cloud and network estates, with the trade-offs stated plainly.

Technical audits of structure, speed and indexing.

We learn your systems and constraints, then agree what done means before anything is built.

We propose an approach, the trade-offs it carries and what it costs to run.

We implement, hand over documentation, and stay available for what follows.
