Zero Trust has been one of the most discussed concepts in cybersecurity for the better part of a decade. For most of that period, it was also one of the least implemented. The architecture requires changes across identity management, network access, endpoint security, and application access policy that exceed the project delivery capacity of most internal IT teams, particularly at mid-market scale. The shift that has made Zero Trust delivery commercially viable at the scale managed service providers serve is the development of mature MSP partnership models by Zero Trust technology vendors and MDR providers who have built their products specifically for the co-managed delivery model.
Managed Detection and Response has undergone the same transition. Three years ago, MDR was effectively an enterprise-only service: the SOC infrastructure, analyst headcount, and detection platform investment required were not economically accessible below a certain scale. Today, MDR vendor partner programmes deliver the detection technology and SOC analyst capacity to MSPs who contribute the client context, relationship management, and on-site response capability. The combination produces an enterprise-grade security service at price points accessible to the SMB and mid-market clients that most MSPs serve. Security-specialised MSPs who have built their practice around Zero Trust delivery and MDR partnerships are among the fastest-growing providers in the market. This article examines why, and how.
Zero Trust: Why the MSP Model Is the Natural Delivery Vehicle
The NIST Zero Trust Architecture publication describes Zero Trust as a collection of concepts and ideas designed to minimise uncertainty in enforcing accurate, least-privilege per-request access decisions. That description captures the architectural principle without conveying the operational reality: implementing Zero Trust requires continuous policy enforcement, continuous access monitoring, and continuous response to policy violations. These are not project activities. They are managed service activities.
Identity as the primary control plane
In a Zero Trust architecture, identity replaces network location as the primary access control mechanism. Every access request is evaluated against the identity of the requesting user and device, regardless of whether the request originates inside or outside the traditional network perimeter. Implementing and maintaining this identity-centric access model requires continuous management of conditional access policies, multi-factor authentication configurations, identity governance workflows, and anomalous access pattern detection. MSPs who manage Microsoft Entra ID or Okta environments for clients are already adjacent to these operational requirements; adding Zero Trust policy management to their service scope is a natural extension of existing work rather than a fundamentally new capability.
Network access control through ZTNA
Zero Trust Network Access replaces traditional VPN-based remote access with application-specific, identity-verified access that does not expose the broader network to the remote user. For clients with remote and hybrid workforces, which is essentially every client in the post-2020 business environment, ZTNA implementation produces immediate and measurable security improvements: lateral movement from a compromised remote session is constrained to the specific applications the user is authorised to access rather than the entire network segment the VPN grants access to. MSPs who have built ZTNA deployment capability through vendor partnerships with Zscaler, Cloudflare, or Palo Alto Prisma provide this capability to clients who cannot implement or maintain it in-house. The technographic data on DiscoverMSPs helps identify which MSPs have built ZTNA delivery into their standard service offerings.
The compliance tailwind for Zero Trust
Zero Trust has moved from an architectural recommendation to a regulatory requirement in several important markets. The US federal Zero Trust mandate, the NIST SP 800-207 framework, and the CISA Zero Trust Maturity Model collectively define Zero Trust as the expected security architecture for federal agencies and their contractors. For MSPs serving the defence industrial base, implementing Zero Trust for clients is no longer a premium service option; it is a compliance requirement that creates immediate demand. This regulatory tailwind is also beginning to affect financial services and critical infrastructure sectors, expanding the commercial opportunity for Zero Trust-capable MSPs well beyond the federal market.
The MDR Partnership Model: How Co-Managed Delivery Works
MDR delivered through MSP partnerships operates on a co-managed model that divides responsibilities between the MDR vendor and the MSP in ways that leverage each party’s comparative advantage.
What the MDR vendor provides
The MDR vendor provides the detection technology platform: the EDR integration, the SIEM correlation infrastructure, the threat intelligence feeds, and the analyst capacity in their SOC who monitor client environments for active threats. The vendor’s analyst team investigates confirmed detections, performs threat hunting across client telemetry, and initiates containment actions for validated incidents according to pre-agreed response runbooks. The vendor’s scale produces detection quality that an individual MSP cannot replicate independently: their threat intelligence is derived from monitoring thousands of environments simultaneously, which provides pattern recognition capability that single-environment visibility cannot match.
What the MSP provides
The MSP provides what the MDR vendor cannot: client relationship context, environmental knowledge accumulated through ongoing infrastructure management, and on-site response capability when containment requires physical intervention. The MSP communicates with the client during and after incidents, translating technical findings into business-relevant impact assessments that the client’s leadership can act on. The MSP also manages the integration of the MDR platform with existing client infrastructure, handles endpoint agent deployment and maintenance, and ensures that the operational context the MDR vendor’s analysts need to investigate events accurately is consistently available and up to date.
Margin structure in MDR partnerships
MDR vendor partner programmes typically price on a per-endpoint or per-user per-month basis, with MSP partner tiers receiving discounted pricing relative to direct client pricing. The MSP marks up the vendor pricing to their client and retains the margin on the difference. The margin percentage varies by vendor, partner tier, and volume commitment, but the best-structured MDR partnerships deliver margins that compare favourably with the MSP’s core managed services business on a per-seat basis. The MSSP segment of the DiscoverMSPs directory provides insight into how MDR delivery is structured across different partner models in the market.

Building a Zero Trust and MDR Practice: What the Fastest-Growing MSPs Are Doing
The MSPs building the strongest Zero Trust and MDR practices in 2026 share a set of strategic decisions that distinguish them from the majority of the market.
Committed vendor depth over portfolio breadth
The MSPs growing fastest in Zero Trust and MDR have committed deeply to one or two vendor partnerships rather than maintaining shallow relationships across a broad portfolio. Deep vendor commitment produces better margin tiers, better technical support, better co-marketing access, and better platform expertise than shallow multi-vendor relationships. An MSP who is a CrowdStrike Falcon Complete partner at the highest tier has materially better support resources and margin than one who has signed up for five MDR programmes at entry tier levels. The same logic applies to Zero Trust: MSPs who have built deep Microsoft or Zscaler Zero Trust expertise win competitive evaluations on the basis of genuine capability rather than vendor-certified knowledge.
Client portfolio segmentation for Zero Trust and MDR target accounts
Not every client in an MSP’s portfolio is an immediate opportunity for Zero Trust architecture or MDR services. The fastest-growing MSPs in this space segment their client portfolio to identify which accounts have the compliance drivers, the security incident history, or the risk profile that makes Zero Trust and MDR an immediate commercial and security priority. These accounts become the initial rollout, generate references, and build the case studies that accelerate adoption across the broader portfolio. Starting with the highest-priority accounts rather than attempting simultaneous rollout across all clients is the approach that consistently produces faster revenue growth and stronger client outcomes. According to Gartner’s Zero Trust research, organisations that begin Zero Trust implementation with identity and privileged access controls achieve the fastest measurable security improvements and the most rapid return on the architecture investment.
Frequently Asked Questions
1.What is Zero Trust and why are MSPs central to its delivery?
Zero Trust is a security model based on verifying every user, device, and access request continuously rather than trusting anything inside the network perimeter by default. MSPs are central to Zero Trust delivery because implementing it requires changes across identity management, network access, endpoint security, and application access policy spanning the exact infrastructure domains MSPs already manage. An MSP with Zero Trust expertise can implement and maintain these controls continuously as an ongoing managed service.
2.What is Managed Detection and Response and how do MSP partnerships deliver it?
Managed Detection and Response combines continuous threat monitoring, AI-assisted detection, human analyst investigation, and active incident response. MDR through MSP partnerships operates co-managed: the MDR vendor provides the detection platform and SOC analyst capacity, while the MSP provides client context, relationship management, and on-site response. This model allows MSPs to offer enterprise-grade MDR to SMB and mid-market clients at sustainable price points.
3.What technology does an MSP need to deliver Zero Trust to clients?
Zero Trust delivery requires MSP capability across five domains: identity and access management with MFA and conditional access; device management with compliance-based access control; ZTNA for network access; application access proxy for internal applications; and continuous monitoring of access events. MSPs without deep expertise in identity and network access domains should partner with a Zero Trust specialist vendor rather than attempting independent delivery from a standing start.
4.How do MSPs price Zero Trust and MDR services?
Zero Trust is typically priced as a project engagement for implementation followed by a recurring managed service fee for ongoing policy management and monitoring. MDR is priced per endpoint or per user per month, with co-managed MSP programmes sharing per-seat revenue between vendor and MSP under a predefined margin split. Both services command premium pricing relative to basic managed IT, reflecting the specialised expertise and continuous operational commitment required.
5.What MDR vendors offer MSP partnership programmes?
Most major MDR vendors operate formal MSP partner programmes. Established programmes include those from CrowdStrike, SentinelOne, Arctic Wolf, Huntress, and Sophos. Evaluate MDR partnerships on the multi-tenant platform quality, depth of analyst support included in the co-managed model, pricing alignment with your billing cadence, and contractual deal registration protections that prevent the vendor from competing directly against you with your own clients.
6.How do MSPs communicate Zero Trust value to SMB clients?
Frame Zero Trust in outcome terms rather than architecture terms. Instead of “Zero Trust architecture,” say: “We verify every device and user before they access your systems, even from inside your office, which prevents ransomware from spreading if one device is compromised.” Outcome-based framing connects the technical architecture to the specific business risk the client already understands. Compliance-driven clients respond to: “This is what your cyber insurance provider and your auditors are now asking for.”
Zero Trust and MDR Are Where the MSP Revenue Is Going
The managed IT services market is stratifying. Basic infrastructure management is becoming increasingly commoditised, with margin pressure from competition and automation reducing the return on standard managed services engagements. The growth and margin in 2026 are in security, specifically in the two categories that require the most ongoing operational expertise: Zero Trust architecture management and Managed Detection and Response.
MSPs who have built their Zero Trust and MDR capability through deep vendor partnerships are not simply offering more services. They are repositioning themselves as security delivery organisations rather than IT management organisations, which commands materially higher average contract values, materially stronger client retention, and materially more durable competitive positioning than basic managed IT services alone can produce.
The starting point for building these capabilities is identifying the right vendor partners, the right client accounts, and the right market intelligence to target both effectively. DiscoverMSPs provides verified data on MSPs with Zero Trust and MDR capabilities across the US and global markets, segmented by technology stack, partnership tier, and client vertical focus.
