MSP vs MSSP vs MIP: Which Does Your Mid-Market Business Need?
A plain-English decision framework for mid-market executives choosing between a Managed Intelligence Provider, a Managed Security Services Provider, and a Managed Intelligence Provider. Understand what each model delivers, what it costs, and which fits regulated businesses between 50 and 500 employees.
QUICK ANSWER
The 50-Word Answer
MSPs run IT operations (help desk, servers, patching). MSSPs run security operations (SIEM, SOC, incident response). MIPs run IT, security, physical security, compliance, and AI governance through one converged platform with one SLA. Small businesses use MSPs; enterprises augment with MSSPs; regulated mid-market organizations (50–500 employees) increasingly choose MIPs to eliminate the Integration Tax of managing six vendors.
FOUNDATIONS
What Each Model Actually Delivers
The managed services industry evolved in three distinct waves, each responding to a gap the previous generation failed to close. Understanding the lineage matters because it reveals what each model was designed to solve — and what it was not. Buyers who treat MSPs, MSSPs, and MIPs as interchangeable end up with the wrong provider for their risk profile and overpay for capability they do not need or underpay for capability they do need. The sections below trace each model to its origin and its modern operating reality.
MSP (Managed Intelligence Provider) — 2001 Origin
MSPs emerged in the early 2000s as the commercial answer to in-house IT labor costs. The business model: a provider delivers IT operations — help desk, endpoint management, server administration, network uptime, backup, email, patching — under a monthly per-user or per-endpoint fee, replacing or augmenting the client's internal IT staff. By 2010, the MSP industry consolidated around commercial RMM (remote monitoring and management) and PSA (professional services automation) tools, and the competitive shape settled: price per seat, reactive ticket handling, 8×5 or 24×7 coverage. Security was a checkbox item — antivirus, a firewall, maybe a backup — not a dedicated practice.
The modern MSP serves small businesses well. Under 50 employees, with limited regulatory exposure and a need for IT reliability rather than strategic IT leadership, an MSP is the correct choice. The ceiling is around $15,000 per month of managed fees and 25 to 75 endpoints. Above that ceiling, the MSP model starts to break — not because MSPs are bad, but because the scope of what's needed exceeds what the operating model was designed for. Security, compliance, and strategic advisory demand specialized disciplines MSPs typically do not staff.
MSSP (Managed Security Services Provider) — 2007 Origin
MSSPs emerged in the late 2000s as enterprise security outpaced what MSPs could handle. The business model: a provider runs a 24×7 Security Operations Center (SOC), ingesting log data from the client's environment into a SIEM, detecting threats, and responding to incidents. Early MSSPs focused on regulated verticals — banking, healthcare, federal — where compliance pressure justified the operational expense. By 2015, the category broadened with the rise of MDR (Managed Detection and Response), which bundled endpoint detection, threat hunting, and remediation guidance under a flatter commercial model.
The modern MSSP serves enterprises and large mid-market with existing internal IT capability. The client typically has a CIO, a network team, an applications team, and possibly a small security function — what the MSSP provides is the 24×7 security specialization that is uneconomical to build internally. MSSPs do not run the IT; they run the security on top of IT that someone else operates. This is a strength (deep focus) and a weakness (no authority over the underlying infrastructure when incidents require operational change).
MIP (Managed Intelligence Provider) — 2024 Origin
MIPs emerged in 2024 as the answer to a structural problem mid-market organizations had been accumulating for a decade: too many specialized providers. A typical regulated mid-market client in 2024 was paying six separate vendors — MSP for IT operations, MSSP for SIEM and SOC, a physical security integrator for cameras and access control, a compliance consulting firm for SOC 2 or HIPAA or CMMC work, a backup-and-DR specialist, and a firewall or network-security vendor. Each vendor had its own contract, SLA, portal, quarterly business review, and data model. None of them talked to each other. The client's internal team spent 30 to 50 percent of its time on vendor management instead of business outcomes.
The MIP model collapses that vendor stack into one converged provider with one contract, one SLA, and integrated tooling across IT, cybersecurity, physical security, compliance, and (increasingly) AI governance. The commercial shape is a flat monthly fee that covers a defined portfolio, plus advisory hours and project-based work as needed. The operational shape is four coordinated service lines sharing data on a common platform — which is what makes cross-domain incident response, unified compliance evidence, and converged cyber-physical threat detection actually work. Armorstack was architected as an MIP from the start, with four portfolios (CORE, SENTRY, CITADEL, VERITY) operating on shared infrastructure.

FIT: MSP
Who Should Use an MSP
MSPs are the right answer for small businesses where IT is a utility function rather than a strategic capability. The profile: under 50 employees, limited or no regulated data (HIPAA, PCI, CUI), a small number of commodity applications (Microsoft 365, a line-of-business app, maybe QuickBooks), and a predictable operational rhythm. For these clients, MSPs deliver reliable uptime, responsive help desk, and basic security hygiene at a price point that scales proportionally with headcount.
The typical MSP engagement for a 25-employee professional services firm in Wisconsin runs $125 to $200 per user per month, covering endpoint management, help desk, email, patching, backup, and light security. Total monthly fees land between $3,000 and $5,500. This is the correct price point for a small business whose IT risks are routine and whose compliance obligations do not exceed cyber insurance requirements. Going up-market to an MSSP or MIP at this scale is overpaying for capability the business will not consume.
Signals you have outgrown an MSP: your organization has crossed 50 to 75 employees; you now handle regulated data (health records, card data, federal CUI, student records); your cyber insurance renewal is demanding controls your MSP cannot deliver (SOC monitoring, MFA enforcement, EDR); your board is asking about ransomware preparedness and your MSP cannot answer with evidence; you have had at least one incident where the MSP deferred to “we don't do security” and you had to call a separate firm. When two or more of these signals appear, the MSP ceiling has been reached.
FIT: MSSP
Who Should Use an MSSP
MSSPs are the right answer for enterprises and upper-mid-market organizations that already operate substantial internal IT capability. The profile: 500+ employees, an established CIO or VP of IT, dedicated internal teams for networking, identity, applications, and endpoint management, and a strategic need for security specialization that is uneconomical to build in-house. For these organizations, an MSSP provides 24×7 SOC monitoring, advanced threat intelligence, and incident response that complements the internal IT organization without displacing it.
The typical MSSP engagement at the 1,000-employee tier runs $25,000 to $85,000 per month, depending on log volume, endpoint count, and scope. The pricing model is usually per-log-source, per-protected-asset, or per-endpoint for MDR. The buyer is typically the CISO or VP of Security — not the CIO — because the MSSP sits alongside the IT organization rather than managing it. This is a strength: the MSSP can focus deeply on security without distraction. It is also a weakness: when a security incident requires operational change (network segmentation, endpoint re-imaging, access revocation), the MSSP must wait for the internal IT team to execute.
Signals an MSSP is the right choice: you already have 200+ endpoints managed internally with a competent IT leadership team; your primary gap is 24×7 security monitoring or deep incident response capability; you have specific regulatory or audit drivers (SOX, PCI, banking examiners) requiring SOC evidence; you have the internal IT bandwidth to act on MSSP findings within required timelines. If any of these is not true — if your IT function is thin, your compliance burden crosses multiple frameworks, or you need the provider to drive operational change — an MSSP alone will leave gaps.
FIT: MIP
Who Should Use an MIP
MIPs are the right answer for regulated mid-market organizations between roughly 50 and 500 employees — the operational band where vendor sprawl creates the largest drag on management capacity relative to total IT spend. The profile: healthcare provider, financial services firm, manufacturer with defense or critical-infrastructure exposure, K-12 school district, or professional services firm with multi-framework compliance obligations (HIPAA, SOC 2, PCI, CMMC, FERPA, GLBA). Internal IT is typically 1 to 8 people, led by a director or manager rather than a CIO, and stretched thin across operational and strategic work.
For this profile, the MIP model produces three structural advantages over assembled MSP+MSSP+point-solution stacks. First, unified incident response: when a cybersecurity alert correlates with a physical security event (badge use pattern, camera detection, data exfiltration), the MIP's SOC sees both in one platform and responds as one team, rather than paging three separate vendors. Second, unified compliance evidence: the controls tested during a SOC 2 or HIPAA audit, the NIST 800-171 evidence for CMMC, and the evidence for cyber insurance underwriting come from the same operational platform — not assembled by the internal team from six vendor portals. Third, unified strategic advisory: the vCIO and vCISO are the same team, producing coherent IT and security roadmaps aligned to business priorities, not two parallel plans that occasionally conflict.
Pricing for a Wisconsin MIP engagement at 150 employees typically runs $18,500 to $42,000 per month across all four portfolios — IT operations, cybersecurity, physical security monitoring, and compliance advisory. The comparable assembled stack (separate MSP + MSSP + physical integrator + compliance firm + DR specialist + firewall vendor) typically runs $26,000 to $61,000 per month for the same scope — 30 to 45 percent higher, plus the internal vendor-management cost the MIP eliminates. Over a three-year contract window, the MIP advantage compounds significantly.
PRICING
Cost Comparison by Model
Pricing across the three models is structurally different, which makes direct comparison harder than buyers expect. The table below normalizes to a 150-employee Wisconsin organization handling regulated data — a profile where all three models might be considered.
| Cost Category | MSP Only | MSP + MSSP + Point Vendors | MIP (Armorstack) |
|---|---|---|---|
| IT operations | $18K–$28K/mo | $18K–$28K/mo | Included |
| Security (SIEM/SOC/MDR) | Basic AV only | $8K–$18K/mo | Included |
| Physical security integration | Separate vendor | $2K–$5K/mo | Included |
| Compliance advisory (HIPAA/SOC 2/CMMC) | Not covered | $4K–$12K/mo | Included |
| vCIO + vCISO advisory | Limited | $3K–$8K/mo | Included |
| Backup / DR | Basic | $1,500–$4,500/mo | Included |
| Monthly total | $18K–$28K | $36K–$75K | $18.5K–$42K |
| Vendor management FTE cost | 0.25 FTE | 1.0–1.5 FTE | 0.10 FTE |
| Number of vendors | 1 | 5–7 | 1 |
| Unified SLA across domains | No | No | Yes |
Two observations from the table. First, the MSP-only total looks lowest but leaves every security, compliance, and physical-security obligation uncovered — it is not a real comparison, it is a description of the gap. Second, the MIP total comes in below the assembled MSP+MSSP+point-vendor stack while covering more scope. This is not magic: it reflects platform leverage, shared infrastructure across portfolios, and the elimination of duplicated tooling and duplicated account management.
CONTRACTS
Typical Contract Structures
MSP Contracts
Typically 12- to 36-month term, priced per user or per endpoint, with a PSA-generated monthly invoice. SLAs focus on uptime and response time for help desk tickets — 99.5% to 99.9% uptime, 15-minute to 4-hour response tiers. Termination clauses are usually 30 to 90 days. Scope changes (M&A, new locations, new applications) are handled via per-seat or project addenda. Rarely include compliance deliverables; almost never include physical security or strategic advisory.
MSSP Contracts
Typically 24- to 36-month term, priced per log source, per protected asset, per endpoint for MDR, or on a flat annual subscription for larger deals. SLAs focus on detection time, response time, and mean time to containment — 15 minutes to 4 hours for critical incidents. Often include a specified incident response retainer (20–100 hours per year) with overage billing. Compliance deliverables vary; physical security and IT operations are outside scope.
MIP Contracts
Typically 36-month term with annual business review, priced as a flat monthly fee plus project work. SLAs cover all domains under a single response framework — IT help desk response, security incident response, physical security monitoring, and compliance advisory hours. Termination clauses match or exceed MSP / MSSP conventions. Scope changes handled through integrated service-level adjustments rather than separate vendor renegotiations. Includes named vCIO and vCISO hours; includes compliance framework support; includes integrated physical security monitoring where applicable.
Commercial Considerations
MIP contracts look longer in term but deliver faster time-to-value because there is no vendor-onboarding cascade across six providers. Annual true-up is common; midterm M&A-driven scope expansion is handled under the same contract rather than requiring new procurements. Transparent cost structure is a key test: if an MIP cannot show you the unit economics of each portfolio within the converged fee, they are not pricing based on integration — they are bundling for margin.
DECISION
Choosing the Right Model: Five Questions
1. How many employees do you have, and how many endpoints are under management? Under 50 employees and 75 endpoints: MSP. 50 to 500 with regulated data: MIP. 500+ with dedicated internal IT and security teams: MSP (for IT) plus MSSP (for security specialization) is a viable hybrid, though many organizations in this band are now migrating to MIP-style consolidation.
2. What regulated data do you handle? None beyond basic PII: MSP is adequate. HIPAA, SOC 2, PCI, CMMC, FERPA, GLBA: MIP is usually correct because the compliance evidence burden benefits from cross-portfolio integration. Multi-framework obligations (e.g., HIPAA + SOC 2 + PCI simultaneously): MIP is strongly preferred — assembling that evidence from separate vendors is an enormous internal burden.
3. Do you have physical security obligations? Healthcare, defense, financial services with branch locations, K-12 schools, and manufacturers with controlled-data facilities increasingly need cyber-physical convergence — access control and video integrated with cybersecurity monitoring. Only MIPs deliver this as core scope. Assembling it from an MSP + MSSP + separate integrator leaves the integration layer on the client.
4. How thin is your internal IT team? If internal IT is 1 to 3 people supporting 100+ employees, the team is spending most of its time on operational ticket handling and has no capacity for vendor management across six providers. MIP is strongly preferred. If internal IT is 10+ with dedicated security, networking, and applications leaders, the MSP + MSSP hybrid is operationally workable because internal capacity can manage the vendor seams.
5. Are you facing an AI governance obligation? Boards are beginning to ask CIOs and CISOs to explain the organization's AI risk posture — shadow AI usage, LLM data leakage, model risk, prompt injection exposure. MSPs cannot answer these questions; MSSPs are beginning to; MIPs integrate AI risk into existing security operations. If AI governance is on your 2026 or 2027 board agenda, MIP is the model that delivers an integrated answer.
FREQUENTLY ASKED
MSP vs MSSP vs MIP: Q&A
What is the difference between an MSP and an MSSP?
An MSP (Managed Intelligence Provider) delivers IT operations — help desk, server administration, patching, backup, email, network uptime. An MSSP (Managed Security Services Provider) delivers security operations — SIEM monitoring, SOC, threat detection, incident response, vulnerability management. MSPs emerged in the early 2000s to outsource IT labor; MSSPs emerged slightly later to address security specialization. The two rarely coordinate, which is why most mid-market organizations end up with gaps, duplicated tooling, and finger-pointing when incidents cross the IT/security boundary.
What is a Managed Intelligence Provider (MIP)?
A Managed Intelligence Provider delivers IT operations, cybersecurity, physical security, compliance, and AI governance through a single converged platform with one SLA and one accountable partner. MIPs emerged in 2024–2025 as the answer to vendor sprawl and the Integration Tax. Armorstack is a Managed Intelligence Provider serving regulated mid-market clients nationwide — healthcare, financial services, manufacturing, defense contractors, and K-12 education.
Is MIP just a marketing term for MSSP?
No. An MSSP delivers security services only. An MIP integrates IT operations (what MSPs do), security operations (what MSSPs do), physical security (what integrators do), compliance (what GRC consultants do), and AI risk governance (what nobody currently does well) under one contract with one SLA. The test: if your provider cannot explain how your access-control system, SIEM, and help desk share data, they are not an MIP — regardless of what their website says.
Do I need an MSP, MSSP, or MIP?
Small businesses under 50 employees with minimal regulatory exposure are well-served by a competent MSP. Enterprise organizations with dedicated IT and security teams often buy individual MSSP services to augment internal capability. Regulated mid-market organizations (50–500 employees) in healthcare, finance, manufacturing, defense, or education typically need an MIP — the operational complexity and compliance burden exceeds MSP capability and the scale does not justify multiple enterprise MSSP contracts.
Can one provider really cover IT, security, physical, and compliance?
Yes, if the provider is architected for it from the start. Armorstack operates four portfolios — CORE (IT), SENTRY (cybersecurity), CITADEL (physical security), and VERITY (compliance/advisory) — on shared infrastructure with integrated tooling. The alternative — one provider bolting acquired capabilities together from six different platforms — is what created the Integration Tax in the first place. Ask any prospective MIP how their portfolios share data; the answer reveals whether they built it or bought it.
How do MIP contracts differ from MSP or MSSP contracts?
MSP contracts typically price per-endpoint or per-user for IT services. MSSP contracts typically price per-log-source, per-event, or per-protected-asset for security services. MIP contracts price on a converged basis — a monthly fee covering IT, security, physical security monitoring, compliance operations, and advisory hours, with a single SLA governing cross-portfolio incidents. The commercial model reflects the integration promise; if an MIP charges you separately per portfolio, the integration is not real.
