System Administration Services
A sysadmin’s discipline, without the headcount.
Servers patched, identity controlled, monitoring watched, access reviewed. The unglamorous work that decides whether your systems hold — run as a practice, not remembered when something breaks.
Delivered entirely remotely — patching, identity and monitoring run as an ongoing practice, wherever your servers live.
Most small businesses don’t need a full-time system administrator. What they need is the discipline of one: patches actually applied, backups actually verified, accounts actually removed when someone leaves, monitoring actually watched by somebody.
That work is invisible when it’s done and catastrophic when it isn’t. Defcor runs it as a standing practice across your servers, identity systems, and cloud services — on a schedule, documented, with someone accountable for it.
What it is
The work that stops problems from starting.
System administration covers server management (physical, virtual, and cloud), operating-system patching, identity and access management, group policy and configuration baselines, monitoring and alert response, capacity planning, and the offboarding hygiene that closes accounts the day someone leaves.
It also covers the part nobody enjoys: keeping records. What’s running where, who has access to what, which licence covers which service, and what the recovery procedure actually is — written down, current, and yours.
How it works
From an unaudited estate to a managed one.
- 01
Audit and document
We inventory servers, services, accounts, and access, and write down what exists — which for most businesses is the first time that record has been accurate.
- 02
Baseline and harden
We bring systems onto a consistent configuration, close the gaps the audit found, and remove the accounts and access that should have ended already.
- 03
Run it on a schedule
Patching, monitoring, access reviews, and capacity checks become recurring work with an owner — not tasks that surface after an incident.
What you get
Standing practice, not occasional attention.
Server management
Windows and Linux servers, on-premise or cloud, kept patched, monitored, and documented rather than left running untouched.
Identity and access
Accounts, groups, and permissions managed deliberately, with joiners and leavers handled the day they happen.
Patch management
Operating system and application patching on a tested schedule, so security updates land without breaking the thing everyone depends on.
Monitoring and response
Alerts that reach a human who acts on them, covering disk, service health, and the failures that precede outages.
Configuration baselines
Machines built from a known standard, so a rebuild is repeatable and a drifted machine is visible.
Access reviews
Periodic checks on who can reach what — the control auditors ask for and most businesses can’t evidence.
Where it lands
Who this is actually for.
Growing teams
Businesses past the point where one technical person can hold it all in their head, but not yet at a full-time sysadmin hire.
Regulated businesses
Practices that need access control and patching they can evidence, not just assert, when an auditor or insurer asks.
Businesses with a departing admin
The person who knew everything is leaving, and nothing is written down. We audit, document, and take it over.
Multi-site operations
Estates where configuration has drifted apart between locations and nobody can say what differs.
Line-of-business software owners
Teams running an application their whole operation depends on, with no one managing the server under it.
Questions
The things owners actually ask.
Yes. System administration is delivered remotely, so we’re not limited by geography for this service. Our on-site work — repairs, cabling, desk-side support — is where being local matters.
More often we work alongside them, taking the recurring discipline so they can focus on the business. When someone is leaving, we can take the whole function over.
Staged rollout with a tested baseline — we don’t push everything everywhere at once. Where a line-of-business application is fragile, we hold and validate before it goes wide.
Yes, and that’s deliberate. Inventory, access records, and recovery procedures are yours. If you ever move on from us, you leave with your own operational knowledge.
Yes — both, on-premise or in cloud. Most environments we take over are mixed whether they meant to be or not.
Offboarding is a defined procedure: accounts disabled, access revoked, devices recovered, licences reclaimed — the day it happens, not the next time anyone reviews it.
The help desk fixes what your people report. System administration is the background work that reduces how often they need to report anything.
