Managed Network in Derry
Managed networks for Derry organisations, where firewall rules accumulate and nothing ever removes one. Every project adds entries, nobody dares delete anything without knowing what it was for, and the rule set grows into hundreds of lines that collectively permit far more than anybody intended.
Why this comes up
The problem
The firewall carries three hundred rules and nobody can say what a third of them were added for.
What you get
What we deliver
- Rules reviewed periodically, with each given a purpose and an owner
- Unused rules identified from traffic data rather than removed on a guess
- New rules required to carry a reason and a review date when added
- Segmentation implemented so a compromise in one area does not reach everything
- Remote access consolidated, since old arrangements linger after their replacement
- Configuration backed up and changes tracked, because these are rarely versioned

Managed Network in Derry — common questions
- Why do rules never get removed?
- Because removing one carries risk and leaving it does not appear to. Nobody wants to be responsible for breaking something whose purpose they cannot establish, so the set only grows — and after a few years it describes access nobody would now approve.
- How are unused rules found safely?
- From hit counts and traffic logs. A rule that has matched nothing in six months is a strong candidate, and disabling before deleting gives a period in which anything genuinely needed reappears as a complaint rather than as a permanent loss.
- Is segmentation worth the effort?
- For most organisations, yes. A flat network means anything compromised can reach everything, whereas separating the parts that have no business talking to each other — office devices, servers, guest access, operational technology — contains an incident considerably.
- What about old remote access?
- It is a common finding. Arrangements set up for a project, a supplier or a previous way of working frequently remain enabled long after replacement, and each is an entry point nobody is monitoring because nobody remembers it exists.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
