Managed IT Services Built for How Your Business Actually Runs
24/7 IT support, helpdesk, infrastructure management, and Microsoft 365 administration, delivered by an outsourced IT team that understands security comes built-in, not bolted on.
Built and led by former Stroz Friedberg leaders. The only outsourced IT support that treats security as a baseline, not an upsell.
Most Growing Businesses Outgrow Their IT Support Long Before They Replace It
The break-fix model worked when environments were simple. It does not work when your team is distributed, your data lives across SaaS apps, and a single misconfigured permission can expose customer data.
Modern managed IT services should keep your business running and keep it secure, at the same time, without trading one for the other.
Slow helpdesk response
Tickets sit while productivity drains.
One-person IT
Coverage gaps when your IT person is sick or on vacation.
Stretched internal team
Strategic work loses to ticket queues every single time.
Security gaps in IT
Your IT provider doesn't think security is their job.
No 24/7 coverage
Issues outside business hours wait until morning.
Tool sprawl
SaaS apps multiply with no central oversight or licensing strategy.
What Modern Managed IT Services Actually Look Like
Managed IT services should give you the operational reliability of a full internal IT department, with the flexibility, expertise, and scalability of an outsourced partner, and with security operating as a baseline rather than an upsell.
Helpdesk, remote, and onsite IT support around the clock, every day of the year.
Patching, monitoring, and maintenance that prevents issues before they reach users.
Microsoft 365, Google Workspace, AWS, and Azure managed by people who run them every day.
Backup, endpoint protection, MFA, and identity hygiene included, not sold separately.

Frequently Asked Questions
What are managed IT services?+
Managed IT services means outsourcing the day-to-day operations of your IT environment to a specialized provider. Defensible handles helpdesk, infrastructure management, Microsoft 365 administration, endpoint management, backup, and the security foundations that should accompany all of it, on a predictable monthly fee.
What does managed IT support cost?+
Managed IT support is typically priced per user per month, with adjustments for the complexity of your environment, after-hours coverage needs, and whether you want fully managed or co-managed service. Defensible provides a clear quote after the initial consultation with no surprise overages.
Is managed IT support a good fit for small businesses?+
Yes. Small and growing businesses are typically where managed IT delivers the highest value. You get senior-level expertise, 24/7 coverage, and security built in for less than the cost of a single internal hire.
Can you co-manage IT with our existing internal team?+
Absolutely. Co-managed IT is one of our most common engagement models. We handle the work your internal team doesn't have time for, helpdesk overflow, after-hours coverage, security operations, and infrastructure management, while your team focuses on strategic priorities.
Do you offer onsite IT support?+
Yes. Most issues are resolved remotely, but onsite support is available when hardware, networking, or office-level work requires hands on the ground.
How long does it take to switch from our current IT provider?+
A standard transition takes two to four weeks depending on environment complexity. We design every transition for zero operational downtime, your team continues working as we take over administration in the background.
