Outages hit everyone at once.
When Microsoft 365 has a bad day, every business on it has the same bad day. Email, calls, files and sign-in tend to go together, and all you can do is refresh the status page and wait.
Managed IT without Microsoft
Leave Microsoft.
Keep working.
We move UK businesses off Windows and Microsoft 365 onto Linux desktops and open-source software that your company owns. Then we run it for you. If you ever leave us, everything stays with you.
Run by Dead Simple Computing, Reading. Cyber Essentials certification body.

Why leave
When Microsoft
has a problem,
so do you.
The bill keeps growing.
Microsoft's prices keep rising, and AI add-ons now sit on top. Every desk carries a Windows licence and a Microsoft 365 seat, whether the job needs them or not.
Microsoft answers to US law.
Microsoft is a US company. Under the US CLOUD Act, US authorities can require it to hand over data it controls, even when that data sits in a UK data centre.
Windows 10 support has ended.
Support ended in October 2025. PCs that can't take Windows 11 need paid security updates or replacing. Most business PCs can run a current, supported Linux for years.
What changes
The tools your team uses, swapped for open source.
Your staff still have email, calendars, shared files, documents, chat and video calls, with one sign-in and MFA. It runs on open-source software, on servers in your company's name.
You stop paying Microsoft for every person who works for you.

Self-custody
The keys stay
with you.
Many IT providers end up holding your accounts and admin passwords, so leaving them becomes a project. We do the work, and everything stays in your company's name.
- 01
Your name on everything.
Domains, servers, hosting accounts and the bills for them are in your company's name, not ours.
- 02
Passwords in your vault.
Admin passwords are kept in a vault you control. We work through named accounts that you can switch off.
- 03
Open formats.
Documents, mail, calendars and contacts use open standards, so nothing is trapped in one app or one supplier.
- 04
Written down.
You get the runbook and the configuration, so another provider or your own team could take over.
- 05
Leave whenever you like.
It's all yours already, so leaving us means changing who has access. There's nothing to migrate back.
How it works
Four steps out.
- 01
Exit call
Thirty minutes on what you use, what you'd like to leave, and what has to stay.
- 02
Exit plan
What moves where, in what order, and a monthly cost side by side with what you pay Microsoft now.
- 03
Pilot
One team moves first, usually on the PCs they already have, so everyone else sees it working.
- 04
Move and run
Everyone else moves. From then on we look after it: updates, monitoring, backups and support.

Lock-in checker
How locked in are you?
Eight yes-or-no questions, about a minute. This site doesn't track you, and your answers stay in your browser unless you choose to send them.
Answer each question. Your score updates as you go. Nothing is sent anywhere until you choose to.
Windows where you need it
Not everything has to go.
Some software only runs on Windows, and some spreadsheets rely on Excel macros. For those, we keep a Windows machine or a hosted app, and move everything else.
When a client sends you a Teams meeting, you join it in your browser.
Still certified
Linux desks pass Cyber Essentials.
Cyber Essentials treats a Linux desktop like any other device. It needs a supported operating system, high and critical security updates within 14 days, a firewall, secure configuration, controlled user accounts and malware protection. A managed Linux desk has all of them, so it can sit inside your Cyber Essentials, Cyber Essentials Plus and Defence Cyber Certification scope.
With less installed on each desk, there's also less to check and evidence.
- Cyber Essentials and PlusCertification body. Also Cyber Essentials Plus certified.
- Defence Cyber CertificationAppointed certification body for Levels 0 and 1.
- ISO 27001 and 9001Certified by 3core2, a UKAS-accredited certification body.
- NCSC Assured Service ProviderUnder the Cyber Advisor scheme.

Who's behind it
“I've always known what Linux could do for a business, I just never had the time to make it work properly. AI changed that.”
nomsp is run by Dead Simple Computing, a managed IT and cyber security company in Reading. Linux has been Daniel's everyday desktop this year, and our own AI assistant runs on a Linux machine in our office. Building and running custom desktops used to need a team of Linux specialists. With today's tooling, and AI doing much of the repetitive work, we can now do it for small and medium-sized businesses.
