Managed IT, Cybersecurity & Microsoft 365 Services Provider

On-Site Technology is a family-owned managed IT services provider headquartered in Clifton, New Jersey, with a second office in Ft. Lauderdale, Florida. We deliver managed IT, cybersecurity, Microsoft 365 and Copilot, cloud infrastructure, VoIP phone systems, and backup and continuity to businesses with 10 to 500 users. We serve clients regionally across NJ, NY, PA, and South Florida, with national delivery for cloud, Microsoft 365, and cybersecurity engagements.

On-Site Technology was founded in 2001 by Lou Garcia and has been serving businesses for over 25 years. Since 2001, we have supported 500+ businesses through Microsoft 365 migrations, office moves, ransomware recoveries, and compliance audits. We are still family-owned and founder-led.

We are built for businesses with 10 to 500 users. That sweet spot covers small businesses past the one-IT-person stage and mid-market organizations that need senior engineering depth without enterprise overhead. We currently serve 200+ businesses in this range across our four-state regional footprint.

Our regional engineering footprint is New Jersey, New York, Pennsylvania, and South Florida, dispatched from our Clifton, NJ headquarters and Ft. Lauderdale, FL office. For cloud, Microsoft 365, Copilot, and cybersecurity engagements that do not require on-site work, we deliver nationally across the United States.

Getting started typically takes four steps. First, we run a free IT assessment to scope your environment, users, and current pain points. Second, we put together a written proposal with tier and pricing options. Third, we onboard your environment with documentation, monitoring agents, and security baselines. Fourth, we run your IT day-to-day with a named senior engineer and quarterly business reviews. Most clients are fully onboarded within 30 to 60 days.

On-Site Technology offers tiered managed IT pricing (Basic, Standard, Premium) typically billed per user per month, plus add-ons for managed cybersecurity, CMMC compliance, backup and continuity, VoIP, and Microsoft 365. Co-managed engagements and project work (Microsoft 365 migrations, office moves, structured cabling, security camera installs, drone services) are scoped separately.

On-Site Technology has been family-owned and founder-led since 2001, with founder Lou Garcia still running the company day-to-day. We assign a named senior engineer to every account, not a first-line call queue. We are built specifically for the 10 to 500 user range, so you get enterprise-grade Microsoft 365 expertise, cybersecurity tooling, and CMMC readiness at small-business pricing, without being forced onto a one-size-fits-all platform. Our regional presence in New Jersey, New York, Pennsylvania, and South Florida lets us dispatch engineers physically; cloud, Microsoft 365, and cybersecurity work is delivered nationally.

On-Site Technology supports HIPAA-regulated healthcare clients, SOC 2-aligned engagements, and CMMC compliance readiness for defense industrial base contractors. We provide the security baselines, documentation, monitoring, and policies your auditors expect. Our managed cybersecurity stack includes SentinelOne EDR, DUO MFA, firewall management, dark web monitoring, and 24×7 SOC coverage. We do not issue compliance certifications ourselves (an auditor does), but we ensure you are technically and procedurally ready when the audit happens, and we maintain the evidence trail your auditor will request.

Yes — that is our co-managed IT services engagement model. We act as an extension of your in-house team, providing senior engineering depth, 24×7 SOC monitoring, advanced security tooling, vendor escalation, project capacity, after-hours coverage, and Microsoft 365 expertise that a small in-house team cannot deliver alone. Co-managed engagements are common for businesses with one to three internal IT staff who need to fill specific gaps (cybersecurity, cloud, M365, after-hours) without losing direct ownership of daily helpdesk and end-user support.

Our Security Operations Center monitors client environments 24×7 for security events, system outages, and patch failures. Most managed-service helpdesk tickets typically see an engineer within 5 to 15 minutes during business hours (Monday through Friday, 8 AM to 6 PM Eastern), with after-hours emergency coverage available on most plans. Premium tiers include extended after-hours and weekend coverage. Critical SOC alerts (suspected ransomware, account compromise, mass outage) target a faster engineer-on-bridge response. Exact response targets are documented in your service agreement and reviewed during quarterly business reviews.
