Managed IT and security, priced per user, run by engineers in Wisconsin

Three packages, one invoice line, no surprise add-ons. Since 1991, TSR has run IT for businesses that would rather not think about it.

Pick the level of cover, not a menu of add-ons

Everything else we do, by the problem it solves

Packages cover the day to day. These are the projects and specialist services around them.

Day-to-day IT run for you, or alongside your team.

Detection, response, testing and leadership that fit a mid-size business.

Private cloud, public cloud, colocation and voice, run by people who answer the phone.

Technology decisions made with a plan, a budget and someone accountable.

Practical AI and automation, scoped to a business problem and secured like everything else.

A scored, written picture of your security or your whole IT stack. Useful whether or not you buy anything else from us.

A one-time review of your technical and operational security that tells you what to fix first and why.

A 123-point review of your technology, from servers to spend, that tells you what to fix, what to keep and what to stop paying for.

Four to six weeks, four workstreams, and billing starts only when the last one closes.

1.Week 1
Discovery and scoping
We learn how your business runs before we touch anything. Engineers document the network, inventory every device and account, review the current backup and security posture, and note any compliance obligations. The device and user counts we agree here are the counts you are billed on.
2.Weeks 2–3
Endpoint security cutover
Defender for Business is onboarded through Intune to the TSR baseline and the detection agent is deployed to every device. Legacy antivirus is removed only after Defender is confirmed active on that machine, and alert routing into TSR is proven with a test detection before we rely on it.
3.Weeks 3–4
SIEM and DNS filtering enablement
We agree which devices and network segments are monitored, then onboard the log sources and verify that logs are leaving each machine. DNS filtering rolls out with an initial category and threat policy that follows laptops off the office network.
4.Weeks 4–5
Identity consolidation
We check the Entra ID baseline for MFA coverage, Conditional Access and self-service password reset, close the gaps, and retire any standalone MFA product once its seats are reconciled to headcount. Inactive licensed accounts are dealt with so you stop paying for people who have left.
