Network design and operations
Design, build, and ongoing operation of the network: segmentation, routing, remote access, and the wireless estate. Segmentation is where infrastructure and compliance meet most directly, since the boundaries you draw here are the ones an assessor will scope against.

Storage design and data management
Storage architecture across on-premises and cloud: capacity and tiering, replication, retention, and backup. Retention and location are frequently regulatory questions rather than technical ones, particularly for controlled data, and are cheaper to answer at design time.
IT administration
Administration of the environment: directory and identity, endpoint configuration, patching baselines, and the operational tooling that keeps an estate current. Delivered as a project or as embedded capacity. Where you want it run for you on an ongoing basis, that is managed services.

Failover and redundancy review
Assessment of what happens when something fails: single points of failure, failover paths that have never been exercised, and recovery objectives that were agreed but not designed for. The common finding is not an absence of redundancy but redundancy that has never been tested end to end.
FinOps
Bringing spend under management as an ongoing practice: attributing cost to the teams and workloads generating it, commitment and reservation strategy, and the reporting that lets a budget conversation happen against real numbers. Distinct from a one-time cost review, which finds savings but does not stop them accumulating again.

Procurement and licensing
Advice on what to buy and what you are already paying for and not using. Licensing in particular is complicated enough that overspend is normal rather than exceptional, and the compliance-driven tiers are among the easiest to over-purchase.
