The best managed IT outsourcing companies for a US business are the ones whose compliance evidence, on-site reach, service scope and scale match the environment you run. A 40-site retailer handling card payments and a bank running IBM Z workloads will end up with different shortlists, even if both open the first sales call asking for 24/7 support.
Managed IT outsourcing means handing some or all day-to-day IT operations to an outside provider under a contract with defined service levels. We compared seven providers on four criteria that decide fit for US CIOs and IT directors: compliance coverage, multi-location support, service scope and enterprise fit.
Full disclosure: this is our blog, and we’ve put Zazz first. We fit regulated mid-market companies best, and we’d rather say so up front. The list below covers the best managed service providers in the US for regulated and multi-site companies, ordered by fit for the reader each entry names. Provider details come from each company’s published materials. We don’t quote other providers’ prices, because a per-user rate means little until you know what it excludes.
Key takeaways
- Pick the outsourcing model before the provider. Fully managed, co-managed and enterprise infrastructure outsourcing suit different organizations.
- Separate a provider’s own certifications from the frameworks it helps you meet. A SOC 2 Type II report on the provider is evidence; “HIPAA support” is a capability claim.
- With several sites, ask who shows up on-site, how fast, and whether that person is an employee or a subcontractor.
- Read the SLA start time and the exit terms before you compare price.
- Among managed IT outsourcing companies, global outsourcers fit mainframe and multi-country estates, and mid-market MSPs fit organizations of roughly 20 to 500 employees that want one accountable team.
How we evaluated managed IT outsourcing providers
Every provider here was assessed against the same four criteria:
- Compliance coverage: the certifications a provider holds for its own operations, and the client frameworks it supports, such as HIPAA, PCI DSS and SOC 2.
- Multi-location IT support: how sites are managed centrally, and who handles hands-on work at each location.
- Service scope: how much of the stack one contract covers, from help desk and endpoints to cloud, security and IT strategy.
- Enterprise fit: the organization size and environment complexity the provider is built around.
The first criterion causes the most confusion in evaluations. A provider with a current SOC 2 Type II report has had an independent auditor test its controls over a period of time. A provider that “supports HIPAA compliance” is describing work it can do in your environment. Both matter, but only the first is evidence about the provider itself, so we keep them apart throughout.
“Most buyers compare price per user and certification logos, then skip the two questions that decide a bad month: when the SLA clock starts, and who physically shows up at each site. Get both answers in writing before you sign. A provider with precise answers has usually already planned for your 6 a.m. outage.”
Hemanth Kumar, VP of Development & Delivery, Zazz
Choose the outsourcing model before the provider
Even the best managed IT outsourcing companies disappoint in the wrong model, so settle this first. With an internal team worth keeping, start your search with co-managed IT providers. If you’re stepping out of day-to-day IT, start with fully managed ones.
Your situation | Model that fits | Provider type to shortlist |
No internal IT team, or you’re stepping out of day-to-day IT | Fully managed | Mid-market or national MSP |
An IT lead or small team that’s stretched | Co-managed | Co-managed IT providers |
Mainframe, SAP or multi-country infrastructure | Enterprise infrastructure outsourcing | Global infrastructure outsourcer |
Many sites needing rollouts, hardware swaps or cabling | Managed services plus field services | Solution provider with field staff |
Expect the mix to change over time. In Deloitte’s 2024 Global Outsourcing Survey of more than 500 executives, 80% planned to maintain or increase their investment in third-party outsourcing. Over the previous five years, though, 70% had also brought some outsourced scope back in-house. A provider that can move you from fully managed to co-managed, and hand work back cleanly, protects you when that happens.
“When we take over after-hours coverage, the first surprise is usually how little of the delay is technical. The fix often takes ten minutes. Finding someone with the access, the runbook, and the permission to make the change takes the rest of the hour. That’s the part we fix first.”
Hemanth Kumar, VP of Development & Delivery, Zazz
Settle the outsourcing model first, then compare providers within it.
Onshore, nearshore or offshore: where the work gets done
Fully managed or co-managed is one choice. Where the people sit is another, and it changes both your compliance review and your response times. Onshore teams in the US and Canada make audits, data residency and on-site visits simpler, which is why finance, healthcare and government buyers often start there. With nearshore IT outsourcing, teams in Latin America and Canada work the same or similar business hours, which suits SLA-driven functions such as help desk and security monitoring. Offshore teams in South Asia cover nights and weekends with the strongest cost efficiency for large-scale operations, so ask for ISO 27001 and SOC 2 controls and a named lead for oversight. Many providers, including us, combine two of these, so ask which team will handle your tickets at 2 a.m. Central.
The 7 best managed IT outsourcing companies for US businesses
1. Zazz: best for regulated mid-market companies with several sites
Best for: US organizations with roughly 20 to 500 employees in healthcare, financial services, legal and other compliance-driven sectors that want fully managed or co-managed IT, a 24/7 North American help desk and security tools included in one per-user price.
We run help desk, IT infrastructure management, cloud and security operations under one contract, with a 24/7 network operations center and a North American help desk team. The team behind our managed IT services holds ISO 27001 certification and a SOC 2 Type II report, along with ISO 9001 and ISO 20000-1, and we provide technical controls, policy templates and audit preparation for HIPAA, PCI, SOC 2 and ISO 27001 programs.
For companies with several sites, we manage firewall policy, VPN tunnels and access controls centrally across offices and remote users, and we send a technician on site when remote support isn’t enough. Every client gets a dedicated Delivery Manager, and we work alongside internal IT teams as well as running IT outright.
2. Kyndryl: best for enterprises running mainframe and hybrid infrastructure
Best for: Large enterprises with IBM Z or IBM i workloads that need to integrate with cloud services.
Kyndryl, the infrastructure services business spun off from IBM, runs IBM Z and IBM i across on-premises, dedicated and shared environments, and manages those estates across customer and Kyndryl environments.

Kyndryl reports it was named a Leader in the 2025 Gartner Magic Quadrant for Data Center Outsourcing Services.
3. DXC Technology: best for large, distributed workforces
Best for: Enterprises that need service desk and workplace support across many countries and languages.
Formed in 2017 when Hewlett Packard Enterprise’s enterprise services business merged with Computer Sciences Corporation, DXC says its workplace services reach 435+ enterprise customers in 70 countries, manage more than 6.9 million devices and support over 36 million contacts a year in 56 spoken and 109 digital languages. It also runs infrastructure, cloud, application and security services.
4. CDW: best for multi-location organizations that need hands-on field work
Best for: Organizations with many sites that want procurement, configuration, deployment and managed services from one provider.
CDW, founded in 1984, sells multi-brand technology to business, government, education and healthcare customers. Its managed services run from operations centers that its brochure puts at six, with 550+ coworkers and 24/7 coverage. One of its managed network service sheets lists local on-site technicians as CDW-contracted, which gives multi-site organizations in-person help for rollouts and hardware swaps.

We left certifications out of the table because they change and audit reports expire. Ask every finalist for current reports during evaluation.
How to choose a managed IT outsourcing provider: six questions to ask before signing
Bring these to every finalist and compare the answers in writing:
- Which audit reports cover the team that will touch our systems? Ask for the SOC 2 Type II report itself, including its audit period and scope, and the ISO 27001 certificate with its scope statement. A certificate covering a different business unit tells you very little.
- Will you sign a business associate agreement, and does it bind your subcontractors? HHS guidance requires written contracts between covered entities and their business associates, and the same requirements apply between business associates and their subcontractors. HHS lists managed services providers that support systems holding electronic health information among its examples of business associates, so a covered entity needs the signed agreement before the provider touches those systems. Hesitation on this point should end the conversation.
- When does the SLA clock start? Get response and resolution commitments by priority, measured from when an incident is detected or reported. A clock that starts at ticket creation can hide an hour of downtime.
- Who shows up at each of our sites, and how fast? List your locations. For each one, ask whether the technician is an employee or a subcontractor and what the on-site commitment is.
- What do we get back when we leave? Documentation, admin credentials, runbooks and configurations should belong to you, with a defined transition period. HHS’s sample agreement provisions say a business associate agreement must require the provider to return or destroy health data at termination, if feasible, and the same discipline belongs on everything else.
- Who are the named people on our account? That means the service delivery lead, the escalation manager and the engineer who knows your environment. Their names belong in the contract.
If we could read only two clauses in a managed IT contract, we’d read the SLA definitions and the termination assistance terms. Price gets negotiated anyway, and those two clauses decide what a bad month costs you. If you’d like a second opinion, we’ll review any proposal against these six questions, whichever provider you’re considering.
Example scenario: one site outage under two contracts
Illustrative example. The company, times and contract terms are hypothetical.
A 250-person logistics company has its head office in Dallas and a warehouse in Memphis. At 6:10 a.m. Central, the warehouse firewall fails, 50 minutes before the morning shift starts scanning orders.
Contract A: remote-only help desk, SLA measured from ticket creation, on-site work billed as projects.
- 6:10 a.m.: The firewall fails. Nobody is monitoring the site overnight.
- 7:00 a.m.: The shift starts, and handheld scanners can’t reach the warehouse system.
- 7:20 a.m.: The IT director opens a ticket. The SLA clock starts now, 70 minutes after the failure.
- 8:05 a.m.: A remote engineer confirms a hardware fault that can’t be fixed remotely.
- 8:15 a.m.: An on-site visit is quoted as a billable project and waits for purchase order approval.
- 1:30 p.m.: A local contractor arrives with a replacement. The warehouse has lost six and a half hours of shift time.
Contract B: 24/7 monitoring, SLA measured from detection, on-site dispatch included, LTE backup at each site.
- 6:10 a.m.: The NOC alert fires as the Memphis site drops offline, and the SLA clock starts.
- 6:14 a.m.: An engineer confirms the internet circuit is up and the firewall isn’t, then opens a priority 1 incident.
- 6:25 a.m.: Traffic fails over to the pre-installed LTE backup. Scanners work before the shift begins, so the shift loses no time.
- 6:40 a.m.: The delivery manager briefs the IT director.
- 8:30 a.m.: A technician swaps in a spare firewall, and its configuration is pushed from central management.
- 9:05 a.m.: A root cause summary is filed.
Contract B’s advantage came from what the contract already paid for: monitoring, a backup circuit and dispatch. Look for those line items when two proposals with similar per-user prices land on your desk.
Illustrative example. What the contract already covers decides how much of the shift you lose.
When managed IT outsourcing isn’t the right call
Outsourcing amplifies the governance you already have. If nobody inside the company owns the provider relationship, reads the monthly reports and pushes back on misses, service drifts. Deloitte found that 70% of executives say their vendor management function isn’t fully mature. Name an internal owner before you sign anything.
Keep work in-house when it’s tied to how you compete. A team that maintains proprietary trading, clinical or manufacturing control systems carries business knowledge that’s slow to transfer and costly to lose. A pattern that holds up well is to outsource the commodity layer (help desk, patching, monitoring, backups) and keep the specialists close.
Check regulated scope early. Defense contractors handling controlled unclassified information typically need providers that support CMMC requirements, and some public sector cloud workloads require FedRAMP-authorized services. Not every commercial MSP is set up for either, so confirm this before anyone makes your shortlist.

Frequently asked questions
What is managed IT outsourcing?
Managed IT outsourcing is a contract under which an external provider runs some or all of a company’s IT operations for a recurring fee and defined service levels. That can include help desk, device management, networks, cloud, backups and security. It can replace an internal IT function (fully managed) or work alongside one (co-managed).
How much does managed IT outsourcing cost for a US company?
Most providers price per user or per device per month, with tiers that add security tools, after-hours coverage or advisory services. As of November 2026, our published per-user pricing is $100 to $150 per user per month across three managed tiers, plus a $50 option for business-hours help desk support only. Essential ($100) includes 24/7 help desk, device management, endpoint and email security, and security awareness training. Professional ($125) adds vCIO advisory and identity administration, and Enterprise ($150) adds vCISO advisory and annual external penetration testing. Enterprise contracts at larger providers are usually priced by service area and scope. Compare any quote by what it excludes, because on-site visits, projects and security tooling are common add-ons.
Is outsourcing IT cheaper than hiring in-house?
It depends on how many hours you need covered and which skills you need. The Bureau of Labor Statistics reports a median annual wage of $99,130 for network and computer systems administrators (May 2025), before benefits, tools and the cost of covering nights, weekends and vacations. At our Professional tier of $125 per user per month, a 100-user company pays about $150,000 a year for a team with 24/7 help desk coverage, security tooling and vCIO advisory included. Count every hire you would need to match that coverage before you compare the two.
What's the difference between co-managed and fully managed IT?
In co-managed IT, your internal team keeps ownership of strategy and some operations, while the provider covers gaps such as overflow tickets, overnight monitoring or specialist skills. In fully managed IT, the provider runs day-to-day operations, and your team handles governance and escalation.
Which certifications should a managed IT outsourcing provider have?
For most US buyers, a current SOC 2 Type II report and ISO 27001 certification are the baseline evidence of a provider’s own controls. Healthcare organizations also need a signed HIPAA business associate agreement. Companies handling card data should confirm what role the provider plays in their PCI DSS scope.
How long does it take to switch managed IT providers?
It depends on the size of the environment and how well it’s documented. As one reference point, we start onboarding within 5 to 7 business days and complete most mid-sized transitions in 2 to 4 weeks. Large enterprise transitions take longer and need a written plan with milestones and a named owner on each side.
Can one provider handle multi-location IT support across several states?
Yes, as long as its tools manage sites centrally and it has a clear on-site model for each location. Ask whether on-site work is done by employees or subcontractors, and get response commitments in writing for each site.
