Problem
Networks tend to grow one change at a time, and the documentation stops matching reality. Security rules pile up, nobody is sure which are still needed, and problems are diagnosed by guesswork. Outages are found when users call.
Outcomes
- A documented network that matches what is running.
- Network security designed around segmentation and least access.
- Reliable connectivity between offices, remote staff and the cloud.
- Monitoring that alerts a named owner before users are affected.
- Changes made through a controlled, documented process.
Scope
In scope
- Network discovery and documentation.
- Network architecture design, including segmentation.
- Wide-area, local and wireless networks.
- Firewall design and rule review.
- Remote access design.
- Network operations and change management.
Not included
- Physical cabling installation. We can coordinate specialist installers.
Observability and monitoring
You cannot fix what you cannot see. We set up logs, metrics and alerts across networks, infrastructure and applications, so problems are spotted early and routed to the right person with enough information to act.
- Health and performance dashboards.
- Alerts routed to named owners, with runbooks.
- Tuning to cut alert noise.
Approach
Discovery
We map the network as it runs today, whatever the old diagrams say. We review the design, the security rules and the performance.
Delivery Planning
We design the improvements, including segmentation and remote access, and agree how each change will be approved, tested and released.
Build and Test
We make changes through a controlled process and test each one. We set up monitoring and alerts across the estate, and check that alerts reach a named owner before go-live.
Operational Readiness, Hypercare and Closure
We carry out each change window and check the network afterwards. We hand over the documentation, dashboards, alert rules and runbooks, and provide extra hypercare for the first few weeks. We then close the work with your sign-off.

Frequently Asked Questions
Our network documentation is out of date. Where do we start?
With discovery. We map what is running and produce documentation that matches it.
What is network segmentation?
Dividing a network into zones so that a problem or attack in one area cannot spread easily to others.
Can you monitor applications as well as networks?
Yes. Observability covers networks, infrastructure and applications.
How do you avoid too many alerts?
We tune alerts so each one is meaningful and reaches the person who can act on it.
Finding out about outages from users?
A Technical Audit reviews your network design, security rules and monitoring in 10 to 15 working days and gives you a prioritised remediation plan.
