Services

Small engagements, written outputs. We are usually brought in where a decision has to be documented.

Technical assurance review

A structured review of an estate against its own stated design and control objectives: network and service topology, identity and access paths, backup and restore reality, change and monitoring practice. Deliverable is a findings register with evidence, not a slide deck.

Regulatory and audit readiness

Preparation for supervisory or certification review under DORA, NIS2, ISO 27001 and sector schemes. We reconcile the control framework with what is actually implemented, and mark clearly where the evidence is missing.

Technical due diligence

For acquirers and investors: cost-to-serve, single points of failure, licensing exposure and the migration work implied by the current architecture. Typically two to three weeks.

Sourcing, transition and exit

Requirements definition, supplier evaluation and a transition plan your own engineers can run. We also run exits — handing a service back from a managed provider without losing the operational history.

We do not resell hardware, hosting or software. Where a supplier is involved, we say so in writing.
