On-Site Technology IT Services for Businesses with 10–500 Users

A managed IT service provider (MSP) takes responsibility for monitoring, maintaining, and supporting an organization’s technology infrastructure on an ongoing basis. On-Site Technology IT Services follow this MSP model. This typically includes 24/7 network monitoring, helpdesk support, patch management, cybersecurity, data backup, cloud administration, and strategic IT planning. On-Site Technology operates as either a fully outsourced IT department or a co-managed partner alongside in-house IT staff, delivering proactive technology management under a predictable monthly fee. Learn more about our Managed IT services.

Managed IT pricing varies based on the number of users, devices, complexity of the environment, and service tier required. Most MSPs, including On-Site Technology, offer flat-rate per-user or per-device monthly pricing that typically ranges from about $100 to $300 per user per month for comprehensive managed support. We provide a free Managed IT Cost Calculator that estimates costs across our Basic, Standard, and Premium tiers. Every engagement begins with a no-obligation technology assessment.

With fully managed IT services, On-Site Technology serves as your complete IT department. With co-managed IT, we work alongside your existing internal IT staff to fill skill gaps, provide overflow support, or cover specialized projects and after-hours coverage. With IT staff augmentation, we place individual contract engineers, administrators, or project managers directly on your team for short or long-term engagements without permanent hiring overhead.

Yes. On-site service — helpdesk dispatch, structured cabling, VoIP installation, security camera installs — is delivered across Northern NJ, the NYC metro, Pennsylvania, and South Florida from our Clifton, NJ and Ft. Lauderdale, FL offices. Our remote-deliverable services — Microsoft 365 administration, Copilot enablement, SharePoint and Teams deployment, penetration testing, CMMC and PCI DSS compliance advisory — are delivered to clients across the United States. About 30% of our compliance and Microsoft 365 client base is currently outside NJ and FL.

Our sweet spot is organizations with 10 to 500 users. Smaller businesses get our full security and compliance practice without the rigid process overhead larger MSPs impose. Larger organizations get a senior team that knows their environment by name, not by ticket number. We also support a number of clients above 500 users where our specialty practices — CMMC, business intelligence, Dynamics 365 — were the better fit than their incumbent provider.

Our cybersecurity practice covers managed cybersecurity with 24/7 SIEM monitoring and endpoint detection, penetration testing aligned to OWASP and NIST SP 800-115, advanced threat intelligence, dark web monitoring, cyber awareness training, MFA and conditional access design, data encryption, and physical security camera systems. Managed Detection and Response (MDR) is included within our managed cybersecurity practice.

Yes. On-Site Technology holds Microsoft Solutions Partner designations covering Modern Work, Security, and Business Applications. For clients, this means our engineers maintain current Microsoft certifications, we have direct escalation paths into Microsoft engineering for complex tickets, and we receive early access to product previews including Microsoft Copilot, Copilot Studio, and the evolving Microsoft 365 security stack. It also means our license advisory work is informed by current Microsoft pricing programs rather than secondhand reseller channels.

Yes. We provide full CMMC 2.0 readiness services for Department of Defense contractors and subcontractors. Our compliance team conducts gap assessments against NIST SP 800-171, develops System Security Plans (SSP) and Plans of Action and Milestones (POA&M), implements required technical controls, and prepares organizations for third-party CMMC assessment by a C3PAO. We also support ongoing continuous monitoring under DFARS 252.204-7012. Try our free CMMC Readiness Checker for a self-assessment across all 14 domains.

For managed IT clients, our team typically acknowledges new tickets within 15 minutes during business hours and aims for first-touch resolution on most P1 (critical) incidents within an hour. P2 and P3 ticket SLAs are documented per contract and tracked in quarterly business reviews. Response targets vary by service tier and severity classification. For specifics on what your environment would look like under our SLA framework, the free assessment is the right starting point.

Yes. We handle the full migration lifecycle — tenant design, data migration from Exchange, Google Workspace, or legacy file servers, identity and conditional access configuration, training, and ongoing administration through our Managed Microsoft 365 service. For Copilot, we run a pre-deployment AI Readiness Assessment to surface data governance gaps, then deploy Microsoft Copilot for Business with appropriate sensitivity labels, retention policies, and end-user training.

We serve manufacturing and warehousing, education (K-12 and higher-ed), government and public safety, non-profit organizations, financial services, and DoD defense contractors. Each vertical has its own regulatory and operational expectations and we maintain dedicated practice depth in each. We are intentionally not a generalist.

Every relationship begins with a free technology assessment. A senior engineer and an account manager spend roughly 60 to 90 minutes reviewing your current environment, security posture, compliance obligations, and pain points. You receive a written summary with prioritized recommendations and a budget range — whether or not you become a client. If we proceed, the next step is a kickoff meeting where we agree on scope, SLA, and onboarding sequence. Most onboardings complete in 30 to 60 days depending on environment complexity.
