8 WSUS alternatives for patch management

Compare the features of eight prominent patch management tools for Microsoft OSes and third-party applications to find the right option for your organization.

IT pros commonly use Microsoft Configuration Manager or Windows Server Update Services to manage patches on Windows Server and desktop systems. Both options are well known, widely deployed and integrated into the larger Windows ecosystem, making either one a natural fit for organizations running Microsoft's OSes.

The patch management features in Configuration Manager, formerly System Center Configuration Manager, which is now part of the Microsoft Intune family of products, can help administrators manage the complex tasks of tracking and applying updates. Configuration Manager includes a set of integrated tools for updating software manually or automatically, as well as controlling when and how patches are deployed. It offers other management functions, giving IT a single tool to carry out many of the tasks associated with administering Windows computers.

Configuration Manager uses Windows Server Update Services (WSUS) to synchronize updates and to conduct update applicability scans. However, organizations don't need Configuration Manager to use WSUS, which is a free server role in Windows Server used to manage and distribute updates. Like Configuration Manager, WSUS provides an integrated tool to patch Windows machines but without the expense or overhead.

Why consider WSUS or Configuration Manager alternatives?

Although many organizations use Configuration Manager and WSUS for Windows patching, both products have limitations. For example, some IT professionals consider Configuration Manager to be expensive and overly complex. The product also offers limited support for non-Windows platforms and applications and must be installed on Windows Server.

Like Configuration Manager, WSUS also has to be installed on Windows Server, which can bring additional licensing fees. The product also has a reputation for being inefficient, cumbersome and buggy at times. In addition, WSUS provides only rudimentary automation and little in the way of reporting capabilities.

Third-party patching tools seek to address these limitations, either by extending WSUS or Configuration Manager or by providing a separate tool for patch management. Third-party tools can help streamline and simplify patching operations, while providing greater control over the patching process. But not all patching tools are the same.

Top WSUS alternatives for patch management

Here, in alphabetical order, is a quick summary of eight prominent WSUS alternatives that each take a different approach to updating the Windows OS and the applications that run on it. Read on for details about all eight products.

1. Automox

Automox, a cloud-based, cross-platform system management tool for patch management, software distribution, reporting and policy enforcement, is not purely a patch management tool, but rather an IT operations system. In addition to its patch management capabilities, Automox can be used for configuration management, software deployment and policy enforcement. Another key feature is single-click remediation of vulnerabilities that have been identified by CrowdStrike, Rapid7 or Tenable.

Automox performs patch management of OSes and applications across a variety of endpoints. Agents are currently available for Windows, macOS and Linux, and Automox can natively patch dozens of third-party applications across the platforms.

Automox is a SaaS product, and the vendor offers two types of subscriptions: Standard and Pro. The Standard plan is geared toward organizations that need patch management capabilities. Besides OS and application patching, it includes features such as full device inventories, basic reporting and end-user notifications. Pro includes all the same features as Standard but adds multizone management, automated vulnerability remediation, remote control and other capabilities.

2. GFI LanGuard

Emphasizing cross-platform patch management and vulnerability scanning for smaller organizations, GFI LanGuard is a network security tool for patch management, network auditing and vulnerability detection. It can be used with or without agents, and its reporting engine has been specifically designed to assist with regulatory compliance for HIPAA, PCI DSS, etc. It recently added generative AI for analytics and automated configuration.

GFI LanGuard supports patch management for Windows, macOS and Linux systems, as well as third-party applications. The software scans managed nodes and identifies missing patches but also checks for over 60,000 known vulnerabilities. If a vulnerability is detected, the software provides a graphical indication of the vulnerability's severity, as well as a recommended course of action. GFI LanGuard is also designed to integrate with over 4,000 security applications. Incidentally, GFI LanGuard's vulnerability scanning is not limited to Windows, macOS and Linux. It also supports Apple iOS and Android and can scan some network hardware, such as printers and switches.

GFI LanGuard is licensed based on the number of nodes to be managed. GFI offers three different licensing plans. Each plan is based on an annual subscription and includes all the same features. The only difference between the plans is the cost, with larger organizations paying less per node. GFI LanGuard is also part of the GFI Unlimited plan, which includes licenses for a number of other GFI products.

3. Ivanti Security Controls

An enterprise-grade tool running on physical or virtual hardware, Ivanti Security Controls, formerly Patch for Windows, is a versatile patch management product for Windows computers, VMs and VM templates.

Security Controls can detect and categorize software and hardware, track asset inventory over time and control a computer's power state, such as shutdowns and restarts. It also gives admins a way to run PowerShell scripts to carry out tasks or automate operations. The REST APIs integrate Security Controls with other products and support remote access and control while offering a method to automate operations.

Security Controls generates multiple reports that provide a variety of information, such as the installed OSes, machine power states, patch deployments and status, and machine compliance. Admins can use database queries to generate custom reports. Security Controls can display applications and their services and components, as well as import the CVE list. It can also show which patches are related to each CVE.
