On-Site Technology Security Stack
Managed Security Services
Our managed security services give businesses with 10 to 500 users two purpose-built bundles. Pick the protection level that fits your risk profile and compliance requirements.
Managed security services deliver outsourced, 24/7 threat monitoring, endpoint detection and response (EDR), email filtering, DNS protection, and vulnerability management through a dedicated security operations center. On-Site Technology offers two bundles: an Essential Security package covering the core protections every business needs, and an Advanced Security + CMMC package that adds NIST 800-171 controls, CUI handling procedures, and audit-ready documentation required for CMMC 2.0 Level 2 certification. Both are available to organizations with 10 to 500 users across New Jersey, New York, Pennsylvania, and South Florida.
What’s in Our Managed Security Services Stack
Every layer of a managed security services deployment works together. Because a gap in any one area gives attackers a way in, each component below is included in both of our bundles. These controls align with the NIST Cybersecurity Framework 2.0 and address the threats that CISA identifies as highest-risk for small and mid-size businesses.
🛡
Endpoint Detection & Response
AI-powered EDR agents run on every workstation and server. As a result, ransomware, fileless attacks, and lateral movement are detected in real time, and compromised devices are isolated before damage spreads. In addition, our SOC reviews every alert so your team never deals with false positives.
📧
Email Security & Phishing Defense
Multi-layered email filtering catches phishing, business email compromise (BEC), and malware attachments before they reach inboxes. Furthermore, link rewriting, attachment sandboxing, and impersonation protection shield executives and finance teams from targeted attacks.
🌐
DNS Filtering & Web Protection
DNS-layer security blocks malicious domains, command-and-control callbacks, and risky categories at the network edge. Because this protection follows the user, it works whether employees are in the office or remote. Policies are also customizable by department or user group.
🔍
Vulnerability Scanning
Scheduled network and application scans identify missing patches, misconfigurations, and exploitable weaknesses. Rather than relying on CVSS scores alone, we prioritize findings by actual risk and track remediation to completion so nothing falls through the cracks.
🔒
Multi-Factor Authentication
MFA enforcement across Microsoft 365, VPN, remote desktop, and line-of-business applications. We deploy, configure, and manage the rollout, including conditional access policies that tighten controls for high-risk sign-ins.
🕰
24/7 SOC Monitoring
A staffed security operations center watches your environment around the clock. Consequently, when something triggers, trained analysts triage the event, escalate genuine threats, and coordinate response within minutes. You get a phone call, not just an email buried in a spam folder.
📊
SIEM & Log Management
Security information and event management (SIEM) aggregates logs from firewalls, endpoints, cloud platforms, and identity providers into a single pane. As a result, correlation rules can detect attack patterns that no single device would catch on its own.
🎭
Dark Web Monitoring
Continuous scanning of dark web marketplaces, paste sites, and credential dumps for your company’s domains, email addresses, and executive names. When stolen credentials surface, we alert you and force password resets before attackers can use them.
🎓
Security Awareness Training
Monthly phishing simulations and micro-training modules keep employees sharp. For example, we track click-through percentages on simulated attacks and then target repeat clickers with additional coaching. The goal is real behavior change, not checkbox compliance.
Two Bundles. One Security Partner.
Not every business needs the same level of managed security services. For instance, defense contractors pursuing CMMC certification have different requirements than a regional accounting firm. That’s why we built two bundles, so you pay for exactly the coverage you need.

Managed Security Services FAQ
Common questions about our managed security services, pricing, and CMMC bundles.
What is the difference between managed security services and managed cybersecurity services?
The terms are often used interchangeably. On our site, managed cybersecurity services is the overarching program, covering our approach, methodology, and NIST CSF 2.0 alignment. This page focuses on the specific tools, technologies, and bundle tiers that make up the security stack we deploy and manage for clients.
How much do managed security services cost per user?
Our Essential Security bundle starts at $20 per user per month. The Advanced Security + CMMC bundle is priced per environment based on user count, server count, CUI scope, and compliance requirements. Both bundles are designed for businesses with 10 to 500 users. Contact us for a quote based on your environment.
Do I need the Advanced bundle if I'm not a defense contractor?
Not necessarily. The Advanced bundle is purpose-built for organizations that handle Controlled Unclassified Information (CUI) or need CMMC 2.0 Level 2 / NIST 800-171 compliance. If you don’t work with the Department of Defense or handle CUI, the Essential bundle provides strong, layered protection against the threats most businesses face. That said, some non-DoD organizations choose Advanced for the enhanced logging, incident response planning, and audit-ready documentation.
What compliance frameworks does the Essential bundle help with?
The Essential bundle supports HIPAA, PCI DSS 4.0, SOC 2 Type II, and most cyber insurance underwriting requirements. It covers the technical controls (EDR, MFA, email security, vulnerability scanning, awareness training) that these frameworks require. For organizations that also need CMMC 2.0 Level 2 or NIST 800-171, the Advanced bundle adds the documentation, encryption standards, and audit preparation those frameworks demand.
How long does it take to deploy the security stack?
Most Essential deployments are fully operational within 10 business days. Advanced deployments, which include SIEM integration, CUI data flow mapping, and SSP documentation, typically take three to four weeks. We phase the rollout so your team is never disrupted. EDR agents deploy silently, email policies go live during off-hours, and MFA is rolled out in waves.
Can I start with Essential and upgrade to Advanced later?
Yes. The Advanced bundle builds on top of Essential. Everything in Essential carries over. When you upgrade, we add the CMMC-specific controls (SIEM, FIPS encryption, CUI handling, SSP/POA&M documentation) without reinstalling or reconfiguring what’s already working. Many clients start with Essential and move to Advanced when they begin pursuing DoD contracts.
What is a System Security Plan (SSP) and do I need one?
A System Security Plan is a formal document that describes how your organization implements each of the 110 security controls in NIST 800-171. It’s required for CMMC 2.0 Level 2 certification. If you handle CUI or plan to bid on DoD contracts, you need one. Our Advanced bundle includes SSP creation and ongoing maintenance. We write it, keep it current, and prepare you for the C3PAO assessment. Learn more on our CMMC compliance page.
Do you provide managed security services in New Jersey and South Florida?
Yes. On-Site Technology (OST) has offices in Northern New Jersey and Broward County, Florida. We provide managed security services across NJ, NY, PA, and South Florida, including Broward, Miami-Dade, and Palm Beach counties. Remote monitoring and SOC coverage work identically regardless of location. For on-site work like network assessments or hardware deployment, our local teams handle it directly.
What happens when the SOC detects a threat?
When our SOC identifies a genuine threat, the response depends on severity. For critical alerts like active ransomware or confirmed compromise, the affected endpoint is isolated immediately and your designated contact receives a phone call within 15 minutes. For medium-severity events, we investigate, contain if needed, and send a detailed summary within two hours. Low-severity events are logged, correlated with other activity, and included in your monthly report. You set the escalation thresholds during onboarding.
How is this different from just buying antivirus software?
Traditional antivirus relies on signature matching. It catches known malware but misses zero-day exploits, fileless attacks, and living-off-the-land techniques that modern attackers use daily. Our managed security stack uses behavioral EDR (not signature-based), layers in email filtering, DNS protection, MFA, and dark web monitoring, and backs it all with human analysts watching 24/7. The difference is the gap between a smoke detector and a fully staffed fire department.
