Patch Management Tools Compared
The patch management tools IT teams use for Windows, Linux and third-party applications — compared on coverage, automation, reporting and cost.
Choosing a patch tool is mostly about two questions: does it patch third-party applications as well as the OS, and can you prove compliance afterwards? Everything else is detail.
How to judge
What separates good patch tools from bad ones
A good patch tool covers your whole estate (OS and third-party applications, on-network and roaming), lets you stage rollouts, and produces evidence an auditor accepts. NIST SP 800-40 Rev. 4 makes the same point at policy level: patching should be routine and measurable, which in practice means the tool must handle the whole loop from detection to verified install — not just the deploy button. If you are new to the discipline, start with what patch management is and come back with your requirements list.
- Third-party application coverage — browsers, Java, PDF readers and media players are heavily targeted; OS-only patching leaves the biggest holes open
- OS coverage — Windows is table stakes; verify genuine Linux distribution and macOS support if you run them
- Ring or group deployment — the ability to pilot before mass rollout
- Scheduling and maintenance windows — patching during business hours is how you lose trust
- Reboot handling — deferral, forced reboot, and knowing which machines are pending
- Reporting — per-device and per-CVE compliance evidence an auditor accepts, ideally mappable to CISA's Known Exploited Vulnerabilities catalogue for prioritisation
- Roaming device support — laptops that rarely touch the office VPN still need patching
The options
The main patch management tools, one by one
These are the tools that actually turn up in patch deployments — from the free Microsoft floor to cloud-native agents and configuration management. For each: what it is genuinely good at, where it falls short, and who it fits.
Microsoft WSUS
Windows Server Update Services is the free, on-premise baseline: it synchronises the Microsoft Update catalogue to a local server, lets you approve updates per computer group, and serves the content on your LAN. For a domain-joined, office-based Windows estate it remains a workable floor, and it is the update engine underneath SCCM's software update point.
Strengths: free with Windows Server, bandwidth-efficient on a LAN, simple approval model. Limits: Microsoft products only — no third-party application patching; no cloud reach, so roaming laptops fall behind; reporting is dated; and Microsoft announced in September 2024 that WSUS is deprecated — still shipped and supported, but with no new features planned. Who it fits: small, static, Windows-only offices with a domain, and organisations already running it under SCCM. Pricing: free with a Windows Server licence.
Microsoft Intune
Microsoft Intune is Microsoft's cloud-native management plane. For patching, it drives Windows Update for Business policies — update rings, deferrals, deadlines and expedited quality updates — plus macOS software update policies, with no on-premise server required. It reaches devices anywhere on the internet, which fixes WSUS's biggest weakness outright.
Strengths: cloud-native reach for remote fleets, ring policies as first-class configuration, tight Entra ID and Autopilot integration, and it is often already licensed through Microsoft 365 plans. Limits: broad third-party application patching is historically weak without add-ons or a separate tool; Linux servers are not its focus; and reporting on precise per-CVE state is thinner than dedicated patch tools. Who it fits: Microsoft-centric, cloud-first organisations, and SCCM shops moving workloads to co-management. Pricing: per-user licensing via Microsoft plans — published price varies, check your Microsoft agreement.
ManageEngine Patch Manager Plus
ManageEngine Patch Manager Plus covers Windows, macOS and Linux with one of the larger third-party application catalogues in the mid-market, available both on-premise and as cloud. It is popular in India and priced for mid-size estates.
Strengths: broad OS plus large third-party catalogue, approval workflows, test-and-approve groups, and compliance reporting out of the box. Limits: the console carries the breadth — expect configuration depth to learn; and as with all suite vendors, capability varies by edition, so verify the specific features you need are in the tier you buy. Who it fits: mid-market teams that want OS and third-party patching in one place without enterprise pricing. Pricing: subscription by estate size and edition — published price varies, check vendor.
Automox
Automox is a cloud-native, agent-based patching platform covering Windows, macOS and Linux. Devices check in over the internet, so office networks and VPNs stop being a dependency — which is exactly the property remote-first fleets need.
Strengths: genuine cross-platform coverage from one agent, policy-based automation (patch everything, patch by severity, patch on a schedule), scripting via Worklets for the gaps, and no server to run. Limits: subscription cost on large fleets adds up; deep Windows-estate features (imaging, application packaging) are out of scope — it patches, it does not replace SCCM. Who it fits: remote-first and mixed-OS fleets that want patching handled with minimal infrastructure. Pricing: per-endpoint subscription — published price varies, check vendor.
Action1
Action1 is cloud patching with a free tier for small estates, which has made it a common first step up from manual updates — you get real central visibility and deployment without a procurement cycle.
Strengths: quick to start, good third-party application catalogue, cloud reach for roaming devices, and the free tier genuinely covers a small fleet. Limits: it is Windows-first — verify current platform coverage against your estate before committing; and larger organisations may outgrow its reporting and role model. Who it fits: small and mid-size Windows-centric teams, especially those starting from nothing. Pricing: free tier for small estates; paid per-endpoint beyond it — published price varies, check vendor.
Ansible, Puppet and Chef
Configuration-management tools patch as a side effect of enforcing desired state: an Ansible playbook that runs package updates across a Linux fleet is a patch deployment, and Windows modules exist too. Powerful and free at the open-source core.
Strengths: total control, no per-endpoint licence, patching integrated with the rest of your automation, excellent for Linux server fleets. Limits: you build and maintain the workflow yourself — detection, severity mapping, ring logic, reboot handling and especially reporting are all DIY; there is no compliance dashboard until you write one. Who it fits: engineering-led teams with automation skills and mostly server estates. Pricing: open source is free; commercial editions and support are separate — check vendor.
NinjaOne, Datto RMM and other RMM platforms
RMM platforms bundle patching alongside monitoring, remote access and scripting — one agent doing several jobs, with per-client separation built in. This is the typical shape for MSPs, and increasingly for lean internal IT teams too; our RMM tools comparison covers the category in depth.
Strengths: one agent and one console for patching, monitoring and remote support; per-client isolation and reporting for MSPs; automation policies across the fleet. Limits: patching depth varies by product — third-party catalogues and Linux coverage differ, so test yours specifically; and you are buying a platform, which is more than you need if patching is the only requirement. Who it fits: MSPs, and internal teams that want patching inside a broader endpoint-management platform. Pricing: per-endpoint subscription, typically bundled with RMM features — published price varies, check vendor.
Infronest Patch Management
Infronest's Patch Management module scans Windows and Linux endpoints for missing patches, deploys in rings on a schedule and reports compliance, using one lightweight agent — inside the same workspace as the asset register, monitoring, VAPT findings and helpdesk.
Strengths: patch state lives next to the asset, the ticket and the vulnerability finding, so a scan finding can be tracked to a deployed patch and verified closure without leaving the platform; no server infrastructure to run. Limits: it is not an SCCM replacement — no OS imaging or application packaging — and macOS patching is not the focus. Who it fits: Windows-and-Linux estates that want patching connected to assets and tickets rather than a standalone console. Pricing and trial details are on the patch management service page.

Which one is right for you
Match the tool to the shape of your estate, not to feature counts. The deciding factors are where your devices live (LAN or internet), which operating systems you run, and whether you need evidence for auditors or clients.
- Small Windows-only office with a domain — WSUS or Intune may be enough.
- Remote-first fleet on mixed operating systems — a cloud-native agent (Automox, Action1, or an RMM with patching) avoids VPN dependency.
- Large domain-joined Windows estate — SCCM remains the depth option if you have someone to run it.
- MSP managing many clients — choose per-tenant isolation and per-client reporting over raw feature count.
- Regulated environment — prioritise reporting and evidence export; you will be asked to prove patch status, not describe it.
- Already running an IT platform — check whether patching is included before buying another agent for every endpoint.

Frequently Asked Questions
- What is the best patch management tool?
- There is no single best. For Microsoft-only estates, Intune or WSUS may suffice. For mixed, remote-first fleets, a cloud-native agent such as Automox or Action1 works well. For MSPs, patching inside an RMM platform with per-client isolation is usually the better fit. Shortlist by estate shape — OS mix, device location, audit requirements — then trial two.
- Does Windows Update count as patch management?
- Not for an organisation. Windows Update patches one machine with no central visibility, no ring control, no third-party application coverage and no compliance reporting. Patch management adds the control and the evidence.
- How do you patch laptops that are rarely on the network?
- Use a cloud-connected agent that reports over the internet rather than a tool that requires the corporate LAN or VPN. Roaming devices are the most commonly under-patched group in most organisations precisely because older tools cannot reach them.
- Is WSUS still supported in 2026?
- Yes, but it is deprecated. Microsoft announced in September 2024 that WSUS would receive no new features; it still ships with Windows Server 2025 and remains supported. It is a reasonable floor for existing static Windows estates, but a poor foundation for new deployments — plan new builds around Intune, a cloud patch agent, or another actively developed tool.
- Can Intune patch third-party applications?
- Intune is strong for Windows and macOS operating system updates via update rings and policies, but broad third-party application patching has historically required add-ons or a separate tool. If Chrome, Java, Zoom and PDF readers are your worry — and they should be — verify exactly how your Intune licensing covers them before relying on it.
- Is there a free patch management tool?
- Three realistic options: WSUS is free with Windows Server but covers Microsoft products only; Action1 offers a free tier for small estates with third-party coverage; and Ansible or similar configuration-management tools are free but leave detection, scheduling and reporting for you to build. Free tools trade licence cost for either coverage or your time.
- What is third-party patch management?
- Patching the applications that do not come from your OS vendor — browsers, Java, PDF readers, collaboration and media tools. These update on their own schedules, are heavily targeted, and are invisible to OS-native tools like WSUS, which is why third-party catalogue coverage is the first differentiator to check in any patch tool.
- How much does patch management software cost?
- Most commercial tools price as a per-endpoint subscription, usually billed annually, with cost driven by fleet size and edition. Free options exist (WSUS, Action1's free tier, configuration-management tooling), and Microsoft estates may already be licensed for Intune. Published prices vary by vendor and region — get quotes against your actual device count.
