The Real Question

Every RMM includes a patch management module. So why would an MSP pay for a separate tool? The honest answer is that most MSPs don't need one. If your RMM handles Windows updates reliably, supports per-client maintenance windows, offers staged approval workflows, and provides compliance reporting, you're covering the majority of your attack surface without adding another vendor to your stack. The case for a dedicated tool emerges when your needs outgrow what the RMM offers: broader third-party application coverage, more granular approval logic, or deployment automation that the RMM can't match. The mistake is adding a dedicated tool before you've actually hit those limitations.

RMM Patching vs Dedicated Platform

Capability	RMM Built-in	Dedicated Platform
Windows OS patching	Strong across all major RMMs	Strong
Third-party app coverage	Limited to moderate (varies by RMM)	Broad (hundreds of applications)
Approval workflow depth	Basic to moderate	Granular with desired-state models
Multi-tenant policies	Yes (per-client/site)	Yes
Agent deployment	Already installed	Requires additional agent
Reporting depth	Adequate for most compliance needs	More detailed, often customizable
Integration with your stack	Native (PSA, alerting, scripting)	Requires API or connector setup
Learning curve	Low (already know the RMM)	Moderate (new console and concepts)
Additional cost	None (bundled)	Per-endpoint license
Best for	Most MSPs under 2,000 endpoints	MSPs needing deep third-party coverage

When RMM Patching Is Enough

For most MSPs managing primarily Windows environments with standard business applications, the RMM's patching module covers the job. The advantages are real: no additional agent to deploy, no additional license cost, no additional console for technicians to learn, and native integration with your alerting, scripting, and PSA workflows. RMM patching works well when your clients run Windows 10/11 workstations and Windows Server, your third-party application footprint is limited to the common set (Office, Chrome, Adobe, Zoom), your compliance reporting needs are straightforward, and your technicians are already proficient in the RMM platform. If that describes your client base, adding a dedicated tool creates complexity without proportional benefit.

When You Need a Dedicated Tool

The case for a dedicated platform becomes clear in specific scenarios. You manage environments with dozens of third-party applications that need patching. You need a desired-state enforcement model where the tool ensures applications stay at specific versions. Your clients have compliance frameworks that require detailed patch audit trails beyond what the RMM provides. Or your RMM's patching module has persistent reliability issues that aren't being resolved. ImmyBot is the most common dedicated tool MSPs adopt alongside their RMM. It connects to the RMM's device inventory and manages software state independently. The desired-state model is genuinely powerful: you define what should be installed and at what version, and ImmyBot enforces it continuously rather than waiting for a scheduled patch cycle.

The hybrid approach

Many MSPs run their RMM for OS patching and add ImmyBot or a similar tool for third-party application management. This gives you the best of both without fully replacing either. If you go this route, make sure to disable overlapping patch policies so the tools don't conflict on reboot scheduling.

Will running two patching tools cause conflicts?

It can if both tools try to manage the same applications or enforce different reboot policies. If you run a hybrid setup, clearly delineate which tool manages which scope. Your RMM handles Windows updates and reboots. Your dedicated tool handles third-party applications without rebooting. Don't let them overlap.

Is the additional cost of a dedicated tool justified?

Calculate the cost of manual third-party patching (technician time per endpoint per month) and compare it to the per-endpoint license cost of the dedicated tool. If the tool saves more labor than it costs in licensing, it pays for itself. For most MSPs, the breakeven point is typically in the range of 300 to 800 endpoints, depending on labor costs and the level of automation in place.

Should MSPs standardize on one approach or let it vary by client?

Standardize wherever possible. Every variation in your patching approach adds complexity to training, documentation, and troubleshooting. If you choose a hybrid model, apply it consistently across clients rather than running different approaches for different environments. The consistency is worth more than the marginal optimization.
