24×7 SOC monitoring, threat detection, incident response, and compliance support for businesses across NJ, NY, PA & FL — 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, vulnerability management, and compliance reporting for a predictable monthly fee. On-Site Technology delivers them across NJ, NY, PA & FL, mapped to NIST CSF 2.0 and aligned to CMMC 2.0, PCI DSS 4.0, HIPAA, NIST 800-171, and cyber insurance requirements.
Every OST managed cybersecurity engagement covers 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. Our service maps directly 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.
Asset inventory, risk assessments, and vulnerability discovery (NIST 800-171, OWASP Top 10) across endpoints, cloud, and identity.
Identity & access control, endpoint hardening, email security, data protection, patching, and cyber awareness training.
24×7 SOC with SIEM/XDR (SentinelOne, Microsoft Defender), MITRE ATT&CK correlation, and dark web monitoring.
Incident response playbooks, containment, forensics, and cyber insurance evidence packets when attacks get through.
Business continuity & disaster recovery (BCDR), immutable backups with Datto, 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.

OST maps managed cybersecurity services directly to CMMC 2.0, NIST 800-171, PCI DSS 4.0, HIPAA, SOX, GLBA, and cyber insurance evidence requirements.
Whether you’re under DoD contract, processing payment cards, handling PHI, or just trying to renew your cyber insurance — we deliver the auditable evidence your framework demands.
End-to-end readiness for DoD contractors handling Federal Contract Information (FCI) or Controlled Unclassified Information (CUI).
CMMC Services →Merchant and service-provider compliance with SAQ prep, network segmentation, annual pen testing, and quarterly ASV scan support.
PCI Services →PHI protection, encryption, audit logging, BAA support, and breach-notification playbooks for practices and covered entities.
Healthcare Compliance →IT general controls, segregation of duties, access reviews, and audit-trail evidence for public-company and financial-services clients.
Compliance Services →Alignment to the U.S. National Institute of Standards and Technology frameworks adopted as the baseline for federal and critical-infrastructure security.
NIST Compliance →Evidence packet for application and renewal — MFA, EDR, backups, pen testing, awareness training, and incident-response retainer proof.
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 10–250 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 — the five sectors most frequently hit by ransomware crews in 2025–2026.
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).

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, vulnerability management, and compliance reporting. 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 your compliance requirements (CMMC, PCI, HIPAA). For most NJ, NY, PA, and FL businesses with 10–250 users, expect monthly fees in the low-three-figures per user range for a full program.

Yes. An MSSP reduces the likelihood and severity of incidents, but cyber insurance covers the financial impact when one occurs — 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. We provide an annual evidence packet specifically 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 certified security analysts (not just an automated ticket); active threat hunting; and direct escalation to your team for any incident requiring action. Every alert is investigated — you do not get a flood of unfiltered noise.
A typical mid-market onboarding runs 30 to 60 days from contract signature to full SOC coverage. Week 1 is discovery and asset inventory. Weeks 2–3 are agent deployment, log source integration, and policy baselining. Weeks 4–6 are tuning, runbook development, and tabletop testing. Critical protections (EDR, MFA enforcement, dark web monitoring) are typically active within the first 7–14 days. Emergency onboarding for active incidents can be expedited — we have onboarded breach-response clients in under 24 hours.
Yes. 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 we guarantee a one-hour response SLA for ransomware and P1 incidents. The playbook: immediate containment (network isolation, endpoint quarantine), forensic preservation, scoping (what’s encrypted, what’s exfiltrated), recovery from immutable backups, regulatory notification support (HHS, state AGs, EU DPAs as applicable), cyber-insurance claim coordination, and a written post-incident report. We do not negotiate ransom payments — that is handled by specialist breach-response counsel and ransomware negotiation firms we coordinate with directly.
Yes. About a third of our cybersecurity clients also 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, compliance — 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 guaranteed boots-on-the-ground incident response within 4 hours from our Clifton, NJ and Fort Lauderdale, FL offices. For clients in other regions we partner with vetted regional incident-response firms when an on-site presence is required.
Standard contracts are 12 or 36 months — longer terms unlock better per-user pricing. We do not lock clients in: every contract includes a 60-day exit clause for material non-performance and we provide a structured offboarding package (configurations, log archives, runbooks, asset inventory) so you are never trapped. Most clients renew — our average client tenure is over 8 years — but our goal is that you stay because the service earns it, not because the contract traps you.
