Managed SOC services built for regulated operations

A Security Operations Center (SOC) is the team, process, and technology that continuously monitors your systems, investigates suspicious activity, and coordinates response when something real is found. VSO’s managed SOC services deliver that capability as a service: 24/7 monitoring, threat detection, and incident response run by U.S.-based analysts, without the multi-year effort of building a security operations program from scratch.

The service is designed for organizations whose environments carry obligations: Defense Industrial Base contractors handling Controlled Unclassified Information (CUI), government programs, and regulated commercial firms in healthcare and financial services. Logging, retention, and incident handling are architected around CMMC (Cybersecurity Maturity Model Certification) and NIST SP 800-171 operating realities rather than bolted on after the fact, and the SOC runs as part of VSO Managed Services, so security operations and IT operations stay connected.

Continuously reduce cyber risk and strengthen defenses.

Vulnerability management
Threat hunting
Security control monitoring
Identity and access monitoring
Risk management

Client portal access

Endpoint coverage pairs the SOC with managed EDR. See endpoint security management for defense contractors for how the endpoint layer fits, and what to look for in SOC as a service when you evaluate any provider, including us.

Attackers do not keep business hours

Adversaries time their operations for when defenders are away. In incidents analyzed by Sophos, 94% of ransomware payloads in 2022 and 90% in 2023 were deployed outside business hours, on nights and weekends, and the median time from initial access to detection has fallen from 13 days to 6. A faster attack against an emptier chair is the whole story of why 24/7 SOC monitoring exists.

Median dwell time in incidents analyzed by Sophos, 1H 2024. Faster attacks leave less time for a business-hours team to catch up on Monday morning.

For defense contractors there is a second clock. DFARS 252.204-7012 requires rapid reporting of qualifying cyber incidents to the Department of Defense within 72 hours of discovery. An intrusion that starts Friday night and is discovered by a Monday-morning team has already spent most of a weekend unobserved. Continuous monitoring keeps discovery, and therefore the reporting clock, inside your control.

We have written at length about coverage models: why cyberattacks do not wait for business hours, why business-hours SOC coverage no longer works for DIB timelines, and the seven questions that verify 24×7 coverage is real before you sign for it.

Should you build a SOC or buy one?

There is no universal answer. Large organizations with the scale to justify a dedicated program can build one, and a hybrid model where a provider covers nights and weekends is often the honest middle ground. For most small and mid-size contractors, the comparison below is why outsourced SOC coverage wins.

Managed SOC Build in-house

Managed SOC services

Coverage 24/7/365 monitoring and response from day one, with staffing depth across shifts rather than an on-call rotation. Staffing Analysts, threat hunters, and incident responders are the provider's problem to recruit, train, and retain. Analyst turnover stops being your detection gap. Tooling SIEM, EDR, and threat intelligence arrive already integrated and tuned, with detections maintained as the threat picture changes. Compliance evidence Logging, retention, dashboards, and incident documentation are produced continuously as part of operations, aligned to CMMC and NIST SP 800-171 expectations. Time to value Weeks to onboard data sources and playbooks, not years to build a program. Best for Organizations that need mature 24/7 detection and response and audit-ready evidence without hiring and running a security team of their own.

In-house SOC

Coverage Real 24/7 coverage requires multiple analysts per shift across nights, weekends, and holidays. Anything less is business-hours coverage with an on-call pager. Staffing You recruit, train, and retain scarce security talent yourself, and absorb the detection gaps that turnover and burnout create. Tooling You select, license, integrate, and continuously tune SIEM, EDR, and intelligence feeds, and keep detections current as attacker tradecraft changes. Compliance evidence Your team designs and maintains the logging, retention, and reporting that assessors and primes expect, alongside its monitoring duties. Time to value Program build-out is typically a multi-year effort before detection and response reach maturity. Best for Large organizations with the scale, budget, and mission need to justify a dedicated security operations program, or hybrid models where a provider covers nights and weekends.

The costs that decide this are rarely the obvious ones. See the managed vs. in-house SOC cost comparison, the hidden costs of building in-house, and why analyst staffing depth is itself a detection control.

Managed SOC Services: FAQs

What is SOC as a service?

SOC as a service is a Security Operations Center run by a provider on your behalf: continuous monitoring, threat detection, investigation, and incident response delivered as a managed service rather than an internal department. You keep ownership of risk decisions; the provider supplies the 24/7 analysts, tooling, and playbooks. VSO's managed SOC services are built for Defense Industrial Base and regulated commercial environments.

What is the difference between MDR and a managed SOC?

Managed detection and response (MDR) is typically a productized detection and response service centered on a vendor's tooling. A managed SOC is a broader operations function: monitoring, detection, response, threat hunting, dashboards, and the compliance evidence and governance around them. For defense contractors, the difference matters for DFARS incident handling; our post on MDR vs. managed SOC under DFARS requirements walks through it.

How much do managed SOC services cost?

Cost depends on asset count, log volume, compliance scope (especially whether Controlled Unclassified Information is involved), and the depth of response you need. We size service tiers after a short scoping session so the quote matches your environment rather than a generic per-seat price. For what drives pricing across the market, see SOC as a service pricing: what to pay, then schedule a scoping call for a formal quote.

Do we still need our own IT team with a managed SOC?

Yes. A managed SOC covers security monitoring, detection, and response; it does not replace the people who run your infrastructure, applications, and helpdesk. In practice the SOC works as an extension of your team: we detect, investigate, and contain, and coordinate with your staff (or with VSO managed IT services) on remediation and recovery.

How does a managed SOC support CMMC and DFARS requirements?

Continuous monitoring, logging, retention, and incident documentation map directly to control families in NIST SP 800-171, and DFARS 252.204-7012 requires rapid reporting of qualifying cyber incidents within 72 hours. A managed SOC keeps that evidence and reporting capability running as a byproduct of daily operations. It supports those requirements; no service makes an organization compliant by itself, because compliance depends on your full scope, controls, and documentation.
