24×7 SOC monitoring, threat detection, and incident response for businesses across NJ, NY, PA & FL, with a Compliance add-on available. From On-Site Technology (OST), a 25-year MSSP.
Managed cybersecurity services are a complete outsourced security program from a Managed Security Service Provider (MSSP) covering 24×7 SOC monitoring, threat detection, incident response, and vulnerability management for a predictable monthly fee. On-Site Technology delivers them across NJ, NY, PA & FL. A Compliance add-on adds NIST CSF 2.0 alignment and reporting for CMMC, PCI DSS, HIPAA, SOC 1 and SOC 2, NIST 800-171, and NIST 800-53.
Our Compliance add-on aligns your program to all six NIST CSF 2.0 functions: Govern, Identify, Protect, Detect, Respond, and Recover.
NIST CSF 2.0 (released February 2024) added Govern as a sixth function, raising the bar for cybersecurity program leadership, risk strategy, and supply chain oversight. The Compliance add-on maps your program to each function so your security investments produce auditable evidence and measurable risk reduction.
Security strategy, policies, roles, and supply-chain risk oversight, the new CSF 2.0 function that anchors all others. Applies to clients on our Microsoft 365 service or Microsoft 365 add-on.
Asset inventory, risk assessments, and vulnerability discovery across endpoints, cloud, and identity. Applies to clients on our Microsoft 365 service or Microsoft 365 add-on.
Identity & access control, endpoint hardening, email security, data protection, patching, and cyber awareness training.
24×7 SOC with SIEM/XDR (SentinelOne and/or Microsoft Defender), MITRE ATT&CK correlation, and dark web monitoring.
Incident escalation to our 24×7 SOC and containment when attacks get through. Cyber insurance evidence packets come with the Compliance add-on.
Business continuity & disaster recovery (BCDR), immutable backups, and ransomware rollback to restore operations fast.
OST delivers eight integrated managed cybersecurity services that work together as a single program, from 24×7 SOC monitoring to ransomware recovery.

Our Compliance add-on covers NIST CSF 2.0 alignment and reporting for CMMC Levels 1 and 2, PCI DSS, HIPAA, SOC 1 and SOC 2, NIST 800-171, NIST 800-53, and cyber insurance evidence.
Whether you’re under DoD contract, processing payment cards, handling PHI, or just trying to renew your cyber insurance, the Compliance add-on produces the auditable evidence your framework demands.
Compliance add-on reporting for CMMC Level 1 and Level 2, for DoD contractors handling FCI or CUI. Full CMMC readiness is a separate add-on.
CMMC Services →PCI DSS reporting through the Compliance add-on. Penetration testing is a separate add-on.
PCI Services →HIPAA / HITECH reporting through the Compliance add-on.
Healthcare Compliance →Alignment to NIST CSF 2.0, SP 800-171, and SP 800-53 through the Compliance add-on.
NIST Compliance →Evidence packet for cyber insurance applications and renewals, through the Compliance add-on.
Insurance Prep →Looking for compliance-focused services on their own? If your primary need is a structured compliance program (audit prep, gap analysis, evidence collection, vCISO support) rather than a full SOC + EDR + incident response stack, see our dedicated Cybersecurity Compliance Services page, built specifically for organizations that already have IT covered and just need the regulatory layer.
Any business in a regulated industry, holding sensitive data, carrying cyber insurance, or running on Microsoft 365 with no dedicated security staff needs an MSSP.
Our service is designed for NJ, NY, PA, and FL businesses with 10–500 users, including organizations across Northern NJ, NYC metro, Philadelphia, and Broward, Miami-Dade & Palm Beach counties in South Florida.
Manufacturing, healthcare, professional services, finance, and local government, sectors that ransomware crews target frequently.
Carriers now require detailed evidence for MFA, EDR, immutable backups, annual pen testing, and awareness training before issuing or renewing a cyber policy.
Defense industrial-base companies handling CUI who must hit CMMC Level 2 to retain or win DoD contracts.
Healthcare (HIPAA), payment processors (PCI DSS 4.0), public companies (SOX), and financial services (GLBA) where non-compliance triggers fines or contract loss.
Businesses recovering from ransomware, BEC, or data-exfiltration events who need permanent, monitored, evidence-backed security, not a one-time cleanup.
Companies too large for consumer-grade tools and too small for a full in-house security team buildout (see comparison table above).
On-Site Technology (OST) has been protecting tri-state and South Florida businesses for 25 years. We bring the tooling stack and process maturity mid-market organizations need.

A Managed Service Provider (MSP) handles general IT operations: helpdesk, patching, server management, network monitoring. A Managed Security Service Provider (MSSP) is purpose-built for cybersecurity: 24×7 SOC monitoring, SIEM, threat hunting, incident response, and vulnerability management. Many businesses use both, but the security workload is too specialized for a general MSP to deliver at depth. On-Site Technology delivers both managed IT and managed cybersecurity services as integrated programs, or each independently if you already have an IT vendor.
Managed cybersecurity services are typically priced per user per month, with the exact rate depending on the depth of services included (SOC, EDR, SIEM, dark web monitoring, awareness training, vCISO support) and whether you add the Compliance add-on (NIST CSF 2.0, CMMC, PCI, HIPAA). Use our free IT cost calculator to estimate, or request a custom quote.
Yes. An MSSP reduces the likelihood and severity of incidents, but cyber insurance covers the financial impact . That includes ransom payment negotiation, regulatory fines, breach notification costs, business interruption, and legal defense. The two are complementary. In fact, working with an MSSP makes you eligible for better cyber insurance rates and broader coverage, because carriers now require proof of MFA, EDR, immutable backups, awareness training, and pen testing before issuing or renewing policies. The Compliance add-on includes an evidence packet for cyber-insurance applications and renewals.
Our 24×7 Security Operations Center includes SIEM-based log aggregation across endpoints, servers, firewalls, identity providers, and cloud apps; behavioral analytics and anomaly detection; managed detection and response (MDR/XDR); real-time alert triage by security analysts (not just an automated ticket); and direct escalation to your team for any incident requiring action.
Most deployments take one to three weeks from contract signature, depending on environment size and scope. We start with discovery and asset inventory, then deploy agents, integrate log sources, and baseline policies, and finish with tuning and runbook development. Critical protections (EDR, MFA enforcement, dark web monitoring) are typically active early in the rollout. Onboarding can be expedited when a client is dealing with an active incident.
Yes, as an add-on to the managed cybersecurity plans. We deliver end-to-end CMMC Level 1 and Level 2 readiness for defense industrial-base companies handling Federal Contract Information (FCI) or Controlled Unclassified Information (CUI). This includes scoping, gap analysis against the 110 NIST SP 800-171 requirements, System Security Plan (SSP) development, Plan of Action & Milestones (POA&M), supply-chain risk evaluation, and pre-assessment readiness with a Certified Third-Party Assessor Organization (C3PAO). See our CMMC Compliance Readiness page for full scope.
For active clients, ransomware and P1 incidents are escalated to our 24×7 SOC. The affected endpoint is isolated, your designated contact is notified, and we send a summary after the incident.
Yes. If you already have an internal IT team or a separate MSP managing day-to-day operations, we layer the cybersecurity program on top (SOC, SIEM, EDR, dark web, awareness training, and a Compliance add-on if you need it) while your existing team continues to handle helpdesk and infrastructure. We document clear handoff procedures so there is no overlap or finger-pointing during incidents. See our Co-Managed IT Services page for the model.
Our managed cybersecurity service operates remotely 24×7 and we serve clients nationwide. The NJ, NY, PA, and FL geographies are where we offer on-site support from our Clifton, NJ and Fort Lauderdale, FL offices.
