Stackline looks after infrastructure, security and custom software for 140 companies of 50 to 2,000 people. Senior engineers on every ticket, a 15-minute response SLA, and one predictable bill per seat.
Certified across the stack you already run
Take one service or all six. Each comes with named engineers, a runbook you can read, and reporting you will actually open.
Laptops, identity, Microsoft 365 and the printer on the third floor. Tickets go straight to an engineer who can fix them, not a queue that forwards them.
EDR on every device, phishing simulation, and analysts watching your logs overnight so nobody on your team has to.
Out of the server cupboard and into AWS, Azure or Google Cloud, with a cost model agreed before anything moves.
Kubernetes, CI/CD and infrastructure as code, so a deploy is a merge rather than a meeting.
480 deploys a week across clients · 0.6% rolled back
Internal tools, integrations and customer portals, built by the same team that will run them.
Immutable backups, a recovery plan with names in it, and a restore test every month that we send you the evidence for.
We put our numbers on the homepage because we report them to every client each month anyway. If we miss one, the credit is automatic.
Across 2,300 managed servers and 41 client networks

The same four steps whether you have twelve laptops or twelve clusters. You own every document we write along the way.
Agents on every device, a read-only look at your cloud accounts, and interviews with the people who get paged.
A written plan with costs, trade-offs and what we would not change. You approve it before we touch anything.
Everything as code, changes in small reviewed batches, and rollbacks rehearsed before the window, not during it.
24/7 monitoring, monthly reporting and a quarterly review where we bring at least one thing to cut.
One price per person covers devices, identity, security and support. Servers and cloud are billed at cost, with no markup.
For teams that need IT to stop being someone’s side job.
For companies whose customers notice when systems are down.
Everything in Essentials, plus
For regulated teams and anyone with an auditor to answer to.
Everything in Professional, plus
Prices in USD, excluding tax. 30-day notice to leave, on every plan, and we hand over every credential on the way out.
