Still sending your sysadmins to the same stale certification factories?
We run small-group courses that actually involve breaking things. Real servers, real configs, real pressure. Not multiple-choice prep — skill-building that sticks past Friday afternoon.

Courses shaped around where your team works
Every organisation runs different stacks and faces different pressure points. We group the curriculum by sector so the labs and case studies mirror what your admins actually handle.
Financial Services & Fintech
High-availability clusters, database failover, and the kind of change-management rigour regulators expect. Labs simulate trading-hour outages. Not fun, but useful.
10 weeks · from £2,200 per seat
Healthcare & Life Sciences
Patient data handling, network segmentation for clinical devices, and disaster recovery that meets compliance frameworks. We've built this track with two NHS trust IT leads — they keep us honest.
8 weeks · from £1,950 per seat
Legal & Professional Services
Document management infra, email archiving, and endpoint security for firms where a breach isn't theoretical — it's a negligence claim. Condensed but thorough.
6 weeks · from £1,600 per seat
Logistics & Manufacturing
Warehouse network design, on-prem/cloud hybrid, and keeping legacy line-of-business applications alive while migrating everything else. It's ugly work. We don't pretend otherwise.
10 weeks · from £2,100 per seat
Education & Research
Multi-tenant campus networks, identity management for thousands of rotating users, and research-data storage. Built with input from two Russell Group IT departments.
8 weeks · from £1,750 per seat
General / Cross-Industry
The all-rounder. Monitoring, patching, backup, and incident response for teams that don't fit a neat vertical. Most popular among MSPs and agencies.
12 weeks · from £1,850 per seat

Why Greylock
Max 16 per cohort
Small enough that the instructor knows every student's weak spots by week three. Large enough to do proper team exercises.
Labs on real infrastructure
Cloud-hosted environments you can break and rebuild. No pre-canned sandboxes. We've seen students crash the DNS — intentionally — and learn more in that hour than in a week of lectures.
Fits around a day job
Two live sessions a week, evenings GMT. Around 7–9 hours total including homework. It's work, but it's doable.
Capstone you can demo
The final project is a working deployment, not an essay. Previous students have shown theirs in interviews. Some were hired partly because of it.
Instructors still work in ops
Not career teachers. Our leads maintain production systems during the week. They teach what they do — not what they remember doing five years ago.
Honest limitation
We're not accredited by a government body. Our certification carries weight in the industry — but if your HR team requires a specific accreditation stamp, ask us first so there are no surprises.
Student stories
“I enrolled my whole team of four. Two of them were sceptical — they'd done vendor-led training before and found it surface-level. By week five everyone was comparing lab notes over lunch. One junior even rebuilt our staging pipeline using patterns from the coursework. That hadn't happened with any prior training we'd tried.”
David Cunningham
Head of IT, Whitmore & Keane Solicitors
“Genuinely challenging. The lab on week six nearly broke me — but that's the point, right? Took a point off because session recordings took a few days to appear, though the live sessions were great.”
Fatima Al-Rashid
Systems Administrator, Kingsley Group
“Recommended. Practical and honest.”
James Poole
Platform Engineer, Greenfield Data Services

Questions we hear a lot
How do you price team enrolments?
We quote per seat with a discount at five or more. The exact amount depends on the track and cohort timing. Request a quote and we'll break it down — no hidden costs, no upsells halfway through.
What if someone drops out mid-course?
One free deferral to the next cohort. After that, £250 re-enrolment. Life happens — we get it.
Are live sessions mandatory?
Attendance matters for the group exercises. You can miss up to two sessions and watch the recordings — beyond that, you're better off deferring. The learning stalls without the live interaction, and we'd rather you get the full value than power through half-present.
Is the certificate worth anything?
Fair question. Look — we're not a government body. But the capstone produces a real deployment you can demonstrate. That portfolio piece tends to open doors the certificate alone wouldn't. It's the work that matters, not the badge.
Can my employer be invoiced directly?
Yes. Roughly 65% of our students use employer-sponsored billing. We also have a template letter you can send to your L&D team to make the business case — just mention it in the quote request.
