Choosing an IT support company is one of the few decisions where you are asked to trust someone with the systems your whole business runs on — and every website says the same three words: proactive, responsive, partner. Tulsa has a healthy market of managed service providers, from firms founded here decades ago to regional companies with a Tulsa office. This list is meant to save you the first afternoon of research: who the established providers are, what each is known for, and how to tell them apart for a business your size.
A note on who wrote this
NSN Management is a Tulsa IT support company, and we are on this list. We have tried to describe every provider fairly, using what they say about themselves and what is publicly verifiable, and we have not ranked anyone by a score we invented. Read our own entry as a plain statement of what we stand for, and use the criteria and questions below to judge all of us — including NSN — for yourself.
How we compared providers
- Local presence. Where the help desk and technicians actually sit, and whether the company is Tulsa-owned, has a Tulsa office, or serves Tulsa from elsewhere in the region. Each model can work; you should know which you are buying.
- Service breadth. Whether the provider covers the whole stack a 10-to-100 person business needs — help desk, monitoring, security, backup, Microsoft 365, phones, cloud, planning — or specializes.
- Security posture. Whether security is built into the standard service or sold as an add-on, and any independent validation (SOC 2, compliance-specific practices).
- Track record and proof. Years in business, industry recognition, and whether the company publishes real, current information rather than a brochure.
- Fit. Who each provider is best suited to — because the right answer for a 300-person multi-site company is rarely the right answer for a 25-person CPA firm.

1. NSN Management
nsnmanagement.com · Tulsa-owned and Tulsa-run since 2012
NSN Management provides fully managed and co-managed IT to Tulsa-area businesses of roughly 10 to 100 people — professional services, CPA and financial firms, engineering and architecture, healthcare and dental practices, contractors, and manufacturers. One flat monthly plan includes the help desk, monitoring and patching, Microsoft 365 administration, the security layer (endpoint detection and response, security operations monitoring, email and DNS protection, awareness training, Microsoft 365 backup), disaster-recovery planning, and virtual CIO planning, with a monthly report against a response standard agreed up front.

Best fit: businesses that want a local team that knows their environment, security included rather than bolted on, and a planning cadence rather than a ticket queue. NSN publishes its typical pricing range.
2. Centre Technologies
centretechnologies.com · Houston-based, with a Tulsa office
Centre Technologies is a well-established regional provider serving Texas and Oklahoma with managed IT, cybersecurity, and cloud services. It is known for enterprise-grade structure — documented processes, standardized service delivery, and industry recognition including MSP 501 and CRN listings — and for supporting organizations with multiple locations. Best fit: larger or multi-site companies that value a formal, process-driven engagement and the depth of a bigger organization.
3. ArcLight Group
arclightgroup.com · Tulsa
ArcLight Group is a Tulsa-based managed IT and cybersecurity provider that has invested visibly in independent validation and content: SOC 2 Type 1 attestation, CMMC-related services for defense supply-chain work, and an active, bylined blog written by its leadership. Best fit: businesses with formal compliance obligations, or those who want a provider whose own controls have been audited.
4. Combined Technology
cttulsa.com · Tulsa, founded 1989
Combined Technology is one of Tulsa’s longest-running IT companies, offering managed and co-managed IT, cybersecurity, and help desk services with explicit coverage of the surrounding suburbs — Broken Arrow, Owasso, Bixby, Jenks, and beyond. Best fit: businesses that weight decades of local track record heavily and want a provider with a footprint across the metro.
5. Jackson Technical
jacksontechnical.com · Tulsa
Jackson Technical focuses on small and mid-sized Tulsa businesses and positions itself as “your IT department” — approachable service, a direct line to your own technician, and a local presence. It offers all-inclusive managed plans as well as block-hour and hourly arrangements. Best fit: smaller businesses that want familiar, responsive support and are not yet ready for a fully managed agreement.
6. Stronghold Data
strongholddata.com · Joplin, Missouri, serving Tulsa
Stronghold Data brings a security- and continuity-first perspective to managed IT: cybersecurity, incident response, and business-continuity planning are central to how it describes itself, and it holds MSP 501 recognition. Best fit: organizations that put security posture and incident readiness at the top of their list and are comfortable with a regional (rather than Tulsa-headquartered) provider.
7. TulsaConnect
tulsaconnect.com · Tulsa
TulsaConnect is one of the longest-established managed IT providers in the city and also operates its own Tulsa data center, which makes it a natural choice for businesses that need colocation, hosting, or local infrastructure alongside support. Best fit: companies with servers or hosted systems that want managed IT and hosting from a single local provider.
8. Custom Computer Solutions
ccstek.com · Tulsa, locally owned
Custom Computer Solutions is a locally owned Tulsa provider focused on small businesses, positioning itself on same-day support for critical issues and on being “locally owned and operated.” Best fit: small businesses that want a straightforward, local relationship and place a premium on quick hands-on help.
9. Pinnacle Business Systems
pbsnow.com · Oklahoma
Pinnacle Business Systems is known for larger technology consulting, infrastructure projects, and hardware — data center work, enterprise systems, and major implementations — rather than for ongoing small-business support. Best fit: organizations with significant capital projects or hardware-driven needs, possibly alongside a separate managed-services relationship.
How to choose between them
Shortlist two or three, then ask each the same questions and compare the answers side by side. The ones that separate providers fastest:
- What exactly is in the monthly fee, and what isn’t? Ask for the inclusions and exclusions on one page.
- What is your written response standard, and what does the monthly report against it look like? Ask to see a real (redacted) report.
- Who answers when we call, and where are they? A local technician who knows your environment, or a call center working from a script.
- Which security controls are standard? Multi-factor authentication, endpoint detection and response, email filtering, patching on a schedule, awareness training — and which of those cost extra.
- How are our backups tested, and when did you last restore one for a client?
- What happens to our documentation and admin credentials if we leave? The right answer is “they are yours, and here is how you get them.”
The full checklist — twelve questions, how to compare proposals, and the red flags — is in How to Choose an IT Company in Tulsa. If you are still deciding between pay-by-the-hour and a managed agreement, this comparison lays out the trade-off, and the 2026 cost guide covers what Tulsa providers charge.

Questions Tulsa businesses ask about this
Who is the best IT support company in Tulsa?
There is no single best — it depends on your size, industry, and what you value. For 10-to-100 person Tulsa businesses that want a local team, security included in the plan, and a planning cadence, NSN Management is a strong choice (Kaseya/Datto MSP of the Year 2025, Inc. 5000 2026, Tulsa-owned since 2012). Larger multi-site organizations often look at Centre Technologies; firms with formal compliance obligations often look at ArcLight Group. Shortlist two or three and ask each the same questions.
How much does IT support cost in Tulsa?
Fully managed IT in Tulsa typically runs about $100 to $175 per person per month in 2026 for a plan that includes the help desk, monitoring, the security stack, backup management, and planning; leaner plans and co-managed arrangements cost less, and hourly break-fix is billed per incident. See NSN Management’s managed IT cost guide for the bands and a worked example.
What is the difference between an IT support company and a managed service provider?
An IT support company may work hourly, on projects, or on a managed basis. A managed service provider (MSP) specifically takes ongoing responsibility for your technology — monitoring, patching, security, backup, help desk, and planning — for a flat monthly fee. Most of the providers on this list offer managed services; some also offer hourly or block-hour options.
Should I choose a Tulsa-based provider or a national one?
Either can work. A Tulsa-owned provider means the help desk and technicians are local, know your environment, and can be on site quickly; a regional or national provider may bring more scale and formal process. Ask where the people who will answer your calls actually sit, and how many of them would recognize your company name.
Is NSN Management really on its own list?
Yes — this is our list, and we say so at the top. We have described every provider fairly using public information, and the criteria and questions in the article are the same ones we would want you to hold us to.
