Zero Trust Security · Derry
Zero Trust Security in Derry
Moving a Derry organisation away from assuming that anything inside the network is trustworthy. Zero trust is a principle rather than a product, which matters because a great deal of software is marketed as delivering it — the actual work is verifying every request rather than trusting location.
Why this comes up
The problem
Being on the office network or the VPN grants broad access. Staff work from anywhere, systems sit in several clouds, and the old inside-outside distinction stopped describing reality.
What you get
What we deliver
- A realistic assessment of where you are, since this is a direction not a purchase
- Identity established as the primary control, with strong authentication throughout
- Device health checked before access is granted, not just user credentials
- Access scoped to what each role needs rather than granted broadly at the perimeter
- Application-level access replacing full network access where possible
- A staged plan, because attempting it all at once disrupts people badly

Zero Trust Security in Derry — common questions
- Can we buy zero trust?
- No, though plenty of vendors imply otherwise. It is an approach — verify explicitly, grant least privilege, assume breach. Products support it; none deliver it. Treating it as a purchase produces expensive tooling around unchanged assumptions.
- Where should we start?
- Identity. Strong authentication everywhere, conditional access based on risk, and administrative rights reduced. That delivers most of the practical benefit before any network redesign, and it is achievable without disrupting how people work.
- Does it replace the VPN?
- Eventually, in many cases. A VPN grants network access, which is exactly the broad trust zero trust removes. Application-level access lets someone reach one system without reaching everything, though migrating away from VPN is a project rather than a switch.
- Will it make things harder for staff?
- Done well, often easier — fewer prompts when the situation is low risk, single sign-on instead of many passwords. Done badly it produces constant authentication and people find workarounds. The staging matters as much as the design.
- 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.
