Third-Party Patching for MSPs: Stop Babysitting Chocolatey, Homebrew, and Apt

You’ve got Windows Update dialed in. WSUS, or your RMM’s built-in patching policy, handles the OS-level stuff on autopilot. Your clients’ machines are getting their monthly Microsoft patches, and life is good — right?

Not quite. The real vulnerability gap isn’t Windows itself. It’s Chrome. It’s Zoom. It’s Adobe Reader, Java, 7-Zip, VLC, FileZilla, and the other 40 third-party applications sitting on your clients’ endpoints doing whatever version they were installed at — often years ago.

That’s where most MSPs get caught out. And if you’re honest about it, you already know your RMM handles third-party patching poorly, or charges you extra to do it, or requires you to build and maintain your own scripts just to push a Chocolatey package.

This post breaks down why third-party patching for MSPs matters more than ever, what the package manager landscape looks like across Windows, macOS, and Linux, and how to stop treating it like a manual side project.

Why Third-Party Software Is Where Attacks Actually Happen

The security industry has spent years drilling the importance of OS patching into IT teams, and that messaging worked. Operating system patch rates have improved significantly across the board. Attackers noticed.

Rather than targeting the OS, modern exploits increasingly target the applications running on top of it. Browsers, PDF readers, media players, collaboration tools, compression utilities — these are the entry points. Many CVEs that result in real-world breaches trace back to unpatched third-party software, not the underlying OS.

The attack surface is wide for a simple reason: most organizations have dozens of third-party applications installed, and no consistent mechanism to keep them current. When your RMM’s native patching only covers the OS and a handful of Microsoft products, everything else is a blind spot.

For MSPs managing hundreds or thousands of endpoints, that blind spot scales with your client count. One unpatched version of a popular browser or PDF reader across 200 seats is 200 potential entry points.

The Three Package Managers Every MSP Should Control

Across Windows, macOS, and Linux, there are three dominant package management systems that handle software installation, updates, and removal. Understanding them — and having the ability to operate all three from one place — is the operational foundation of a solid third-party patching program.

Chocolatey: Windows Third-Party Patching at Scale

Chocolatey patch management is the de facto standard for automating software on Windows endpoints. It works like a command-line package manager — you specify a package name, and Chocolatey handles the download, installation, and versioning against a curated community or private repository.

The library of available packages covers the vast majority of business software MSPs deal with: Google Chrome, Mozilla Firefox, Zoom, VLC, 7-Zip, Notepad++, Adobe Reader, Java, and thousands more.

The problem MSPs run into isn’t that Chocolatey doesn’t work — it does. The problem is operationalizing it across client environments. You need scripts. You need a way to run those scripts remotely. You need to track what’s installed, what version, and what needs updating. You need to handle failures. Done manually, it’s a part-time job.

Homebrew: The macOS Gap Most MSPs Ignore

Mac endpoints have become a fixture in most MSP client environments. Homebrew is the package manager that governs third-party software on macOS — the equivalent of Chocolatey for the Apple ecosystem.

Homebrew management for MSPs is genuinely underserved. Most RMM platforms have reasonable Windows patching stories, but macOS third-party patching is often an afterthought. Homebrew handles both command-line tools and GUI applications (via Homebrew Cask), covering the same class of software — browsers, productivity tools, developer utilities, media players — that you’re managing on Windows.

If your Mac endpoints are running outdated versions of Chrome, Zoom, or other business-critical software, the vulnerability exposure is identical to Windows. The OS being different doesn’t change the risk profile of the applications on top of it.

Apt, Yum, and Zypper: Linux Isn’t Exempt

Linux endpoints and servers are increasingly part of MSP-managed environments. Whether it’s Ubuntu workstations, CentOS servers, SUSE-based infrastructure, or mixed fleets, Linux machines running outdated packages carry the same risks as any other endpoint.

The major Linux package managers — Apt-Get (Debian/Ubuntu), Yum (RHEL/CentOS), and Zypper (openSUSE/SLES) — each handle software installation and updates for their respective distributions. Managing them across a heterogeneous Linux environment means knowing which distro you’re on and using the right tool for each.

For MSPs, the operational challenge is the same as with Windows and macOS: visibility, consistency, and scale. Logging into individual machines or writing distribution-specific scripts is not a patching program — it’s firefighting.

The Real Problem: Three Ecosystems, Zero Unified Control

Here’s the situation most MSPs are actually in when it comes to automating software updates across their managed environment:

• Windows Chocolatey patching is handled by a mix of RMM scripts that somebody wrote two years ago and mostly still works
• macOS Homebrew updates get done ad-hoc, if at all, because there’s no clean workflow in the RMM
• Linux package management is handled by a senior tech who SSHs into machines when something breaks
• There’s no unified view of what’s installed, what version, or what’s out of date across any of these platforms

This isn’t a people problem. It’s a tooling problem. Most RMMs were built when Windows was the only OS that mattered in managed environments. Their third-party patching capabilities reflect that history. Bolted-on add-ons, expensive integrations, and limited package coverage are the norm — not the exception.

What Unified MSP Software Deployment Actually Looks Like

The goal is straightforward: deploy, update, and remove third-party software packages across Windows, macOS, and Linux from one console, without writing custom scripts or maintaining package lists manually.

That’s exactly what RMMmax 2.0 delivers. It provides full software and package management across all three operating systems — Chocolatey for Windows, Homebrew for macOS, and Yum, Apt-Get, and Zypper for Linux — from a single interface.

Rather than replacing your existing RMM, RMMmax layers on top of it. It integrates via API with NinjaOne, Kaseya, Datto, ConnectWise Automate, Tactical RMM, and ScreenConnect, so the agents you already have deployed become the execution layer. You’re not ripping anything out — you’re adding the capability your current stack is missing.

What This Changes for MSP Operations

Having all three package managers under one roof changes the operational model for MSP software deployment in a few concrete ways:

• Cross-platform visibility: See what’s installed and what version across Windows, macOS, and Linux endpoints in one place, rather than toggling between platforms or running separate queries
• Consistent update workflows: The same process for pushing a Chrome update to Windows machines applies to macOS machines — you’re not learning a different interface or writing different scripts
• No script maintenance: Package manager integrations are built in. You’re not maintaining a library of PowerShell scripts or bash scripts that break every time an application changes its install path
• Removal as well as deployment: Decommission software across client environments with the same ease as deploying it — useful for license management, offboarding, and removing vulnerable software quickly

Practical Starting Point: Where to Focus First

If you’re building out or overhauling your third-party patching practice, prioritize the software with the highest exposure and the largest installed base across your clients. In most MSP environments, that list looks something like this:

• Web browsers (Chrome, Firefox, Edge)
• PDF readers (Adobe Acrobat Reader, Foxit)
• Video conferencing clients (Zoom, Teams, Webex)
• Java runtime (still present in more environments than it should be)
• Compression utilities (7-Zip, WinRAR)
• Media players and viewers (VLC, IrfanView)
• Developer and utility tools present in mixed environments

These are high-frequency targets in real-world exploitation precisely because they’re ubiquitous and historically under-patched. Getting them current — and keeping them current automatically — removes a meaningful portion of your clients’ attack surface without requiring a major project.

Stop Treating Third-Party Patching as a Manual Task

The MSPs that handle this well aren’t smarter or better staffed. They have better tooling. Third-party patching doesn’t need to be a monthly ticket someone works through manually. It doesn’t need custom scripts that break and get ignored. It doesn’t need a separate product license for every OS platform you support.

It needs a consistent, cross-platform workflow that runs without babysitting — one that covers Chocolatey on Windows, Homebrew on macOS, and Apt/Yum/Zypper on Linux from the same console you’re already using to manage endpoints.

That’s the gap RMMmax fills. And given the vulnerability exposure sitting in unpatched third-party software across most managed environments, it’s worth closing sooner rather than later.
