Many Columbia, MD businesses — especially defense contractors — need both. The right provider can deliver co-managed IT and dedicated security under one roof, so nothing falls through the cracks.
If you've been shopping for IT support in the Columbia, Maryland area, you've probably seen both terms: MSP and MSSP. They sound nearly identical. But for businesses handling sensitive data — especially those working with the Department of Defense — the distinction matters enormously.
Getting this wrong isn't just a technology problem. It's a compliance problem. Defense contractors pursuing CMMC certification, healthcare organizations subject to HIPAA, or any company handling payment card data under PCI-DSS need more than a help desk — they need a security partner. But many businesses that need standard IT operations also exist in that world.
This guide breaks down exactly what MSPs and MSSPs do, where they overlap, what co-managed IT looks like, and how to decide which model — or combination — fits your organization. If you'd like to talk through your specific situation, CISPOINT offers a free IT and security assessment for businesses in the Columbia, MD region.
What Is a Managed Service Provider (MSP)?
A Managed Service Provider is a company that takes over the day-to-day management of your IT environment — typically for a flat monthly fee. Think of an MSP as your outsourced IT department. Instead of hiring an internal team of network engineers, system administrators, and help desk technicians, you pay a single provider to handle all of that.
Core Services MSPs Typically Provide
- Help desk and end-user support (password resets, software issues, device problems)
- Network monitoring and management
- Server and workstation maintenance
- Backup and disaster recovery
- Software patching and updates
- Email and productivity suite management (Microsoft 365, Google Workspace)
- Vendor coordination for hardware and software
- IT procurement and lifecycle management
MSPs are primarily operationally focused. Their job is to keep your technology running. They may offer basic security practices — antivirus, firewall management, patch cycles — but deep cybersecurity is generally outside their core competency.
What Is a Managed Security Service Provider (MSSP)?
A Managed Security Service Provider is a specialized firm focused exclusively — or primarily — on cybersecurity. Where MSPs handle IT operations, MSSPs handle your security posture, threat detection, and compliance requirements.
MSSPs typically operate a Security Operations Center (SOC), staffed around the clock with security analysts who monitor your environment for threats, investigate alerts, and respond to incidents. This 24/7 coverage is a defining characteristic of true MSSPs and one of the most significant differences from traditional MSPs.
Core Services MSSPs Typically Provide
- 24/7 Security Operations Center (SOC) monitoring
- Security Information and Event Management (SIEM) — log collection, correlation, alerting
- Endpoint Detection and Response (EDR)
- Vulnerability management and penetration testing
- Incident response and forensics
- Compliance management (CMMC, HIPAA, PCI-DSS, NIST)
- Threat intelligence
- Identity and access management (IAM)
- Zero Trust architecture planning and implementation

MSP vs. MSSP: Side-by-Side Comparison
The table below covers the most important distinctions between MSPs and MSSPs across the areas that matter most to businesses in regulated industries.
| Category | MSP | MSSP |
| Primary Focus | IT operations and infrastructure | Cybersecurity and compliance |
| Help Desk Support | Yes — core service | Sometimes; depends on provider |
| 24/7 Security Monitoring | Rarely included | Yes — core service (SOC) |
| SIEM / Log Management | Typically not included | Yes — typically included |
| Compliance Support (CMMC, HIPAA, PCI) | Limited | Yes — core competency |
| Incident Response | Basic at best | Yes — dedicated capability |
| Vulnerability Management | Patch management only | Full program with remediation |
| Threat Intelligence | Not typically included | Yes |
| Pricing Model | Flat monthly per-user/device fee | Variable; often tiered by coverage level |
| Best For | SMBs needing reliable IT operations | Regulated industries, gov contractors, high-risk environments |
What Is Co-Managed IT — and Do You Need It?
Co-managed IT is a hybrid model designed for businesses that already have some internal IT staff but want to supplement their capabilities with an outside provider. Rather than fully outsourcing your IT function, you and your MSP (or MSSP) share responsibilities.
This model is increasingly popular among mid-sized defense contractors and government-adjacent businesses in the Columbia, MD area — organizations large enough to warrant an internal IT person but complex enough to need deeper security expertise than one person can provide.
How Co-Managed IT Typically Works
- Your internal team handles day-to-day user support, on-site issues, and relationship management
- The external provider handles specialized areas: security monitoring, compliance documentation, advanced threat response, infrastructure architecture
- Both teams operate from a shared toolset and documented responsibilities — no gaps, no duplication
- The external provider scales up during incidents or compliance assessments, without you needing to hire permanently
For defense contractors, co-managed IT with an MSSP component is often the most cost-effective path to CMMC compliance — you bring the business context, they bring the security infrastructure.
Why 24/7 Security Support Matters — Especially for Defense Contractors
Cyber threats don't observe business hours. Ransomware attacks, credential harvesting campaigns, and supply chain intrusions frequently occur overnight, on weekends, and during holidays — precisely when most IT teams are unavailable.
For defense contractors, the stakes of a security incident extend beyond operational disruption. A breach involving Controlled Unclassified Information (CUI) can trigger mandatory reporting obligations to the DoD, jeopardize your ability to bid on future contracts, and in some cases result in loss of your facility clearance.
What True 24/7 Coverage Looks Like
- Live analysts (not just automated alerts) reviewing your environment around the clock
- Defined escalation paths — you're notified immediately when something real is happening
- Documented response procedures aligned with NIST SP 800-61 (incident response)
- Regular threat hunting — proactively searching for indicators of compromise, not just reacting to alerts
- Integration with your endpoint, network, and identity tools so nothing is a blind spot
Not all providers that claim "24/7 monitoring" deliver the same thing. Some use automated alerting with a small team that reviews alerts during business hours. When evaluating providers, ask specifically: how many analysts are staffed at 3am on a Sunday? What is your mean time to respond for a critical alert? For more context, see CISPOINT's CMMC compliance resources.
Which Does Your Business Need? A Decision Framework
The honest answer is: it depends on your regulatory environment, your risk profile, and your existing internal capabilities. Here's a practical framework based on common business profiles we see in the Columbia, MD and broader DMV region.
| Business Profile | Recommended Model |
| Small business, no regulatory requirements, needs basic IT support | MSP only |
| Growing business with compliance needs (PCI, HIPAA) but no government work | MSP with security add-ons, or MSSP |
| Defense contractor pursuing CMMC Level 1 (self-attestation) | MSP with security guidance from an RPO-registered partner |
| Defense contractor pursuing CMMC Level 2 (third-party assessment) | MSSP or MSP/MSSP combo with CMMC expertise |
| Company with internal IT staff needing security depth and compliance support | Co-managed IT with MSSP component |
| Healthcare organization subject to HIPAA + government contracts | Full MSSP with multi-framework compliance support |
Questions to Ask When Evaluating Providers
- Are you a Cyber-AB Registered Practitioner Organization (RPO) or a C3PAO?
- Do you have experience with CMMC Level 2 assessments?
- What does your SOC staffing look like? Is it 24/7 with live analysts?
- Can you support both IT operations (help desk, infrastructure) and security monitoring?
- How do you handle CUI — do your own tools and processes meet CMMC requirements?
- What compliance frameworks do you actively support (NIST 800-171, HIPAA, PCI-DSS)?
- Can you provide references from defense contractors you've supported through CMMC?
Why Some Columbia, MD Businesses Choose an RPO That Does Both
One challenge businesses face when evaluating MSPs and MSSPs separately is integration. If your MSP and MSSP are two different companies, you have two contracts, two support relationships, and — critically — two potential gaps where each assumes the other is handling something.
For defense contractors in particular, fragmented IT and security creates a CMMC compliance challenge. CMMC assessors look at your total environment. If your MSP manages your Microsoft 365 tenant but your MSSP doesn't have visibility into it, you have a gap. If your MSSP monitors your servers but doesn't know which employees recently departed, you have a gap.

Frequently Asked Questions
Can an MSP become my MSSP if they add security tools?
Not automatically. Adding an antivirus product or a firewall to an MSP's stack doesn't make them an MSSP. True MSSPs have dedicated security analysts, a SOC, defined incident response capabilities, and compliance expertise. When a provider says they "do security," ask specifically: do you have a 24/7 SOC with live analysts? What is your incident response process? What compliance frameworks do you actively manage?
What is a Cyber-AB RPO and why does it matter?
A Cyber-AB Registered Practitioner Organization (RPO) is a company officially recognized by the CMMC Accreditation Body to provide CMMC advisory services. Working with an RPO means your consultant has met baseline requirements and is accountable to the Cyber-AB's code of professional conduct. For defense contractors, this matters because not all "CMMC consultants" are credentialed — and bad advice can be expensive. See CISPOINT's CMMC compliance page for more.
My current MSP says they handle security. Should I trust that?
Ask them these questions: Do you have a dedicated SOC? Are analysts monitoring my environment at 3am? Do you have CMMC, HIPAA, or PCI experience? Can you produce documentation of security practices aligned to NIST 800-171? If the answers are vague, you likely have IT operations coverage but not true security management.
How does co-managed IT work if I only have one IT person?
Co-managed IT works especially well with a lean internal team. Your internal person focuses on relationship management, day-to-day user support, and business-specific context. The external provider handles specialized areas — security monitoring, compliance management, advanced troubleshooting, architecture decisions. The key is a clear responsibility matrix so nothing falls through the cracks.
Does CMMC Level 2 require a specific type of IT provider?
CMMC Level 2 doesn't mandate that you use a specific provider type, but it does require you to implement and document 110 security practices from NIST SP 800-171. Many of those practices require capabilities — like continuous monitoring, vulnerability management, and incident response — that most internal IT teams can't deliver alone. An MSSP or integrated MSP/MSSP partner with CMMC expertise is typically the most practical path. Read more in our Complete CMMC 2.0 Guide.
