8 WSUS alternatives for patch management

Compare the features and functionality 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 System Center 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 computers on Microsoft's operating systems.

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

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

Why consider WSUS or SCCM alternatives?

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

Like SCCM, 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 SCCM 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. 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.

Top WSUS alternatives for patch management

  1. Automox. A cloud-based, cross-platform system management tool for patch management, software distribution, reporting and policy enforcement.
  2. GFI LanGuard. Cross-platform patch management and vulnerability scanning for smaller organizations.
  3. Ivanti Security Controls. An enterprise-grade tool for Windows and Linux systems running on physical or virtual hardware. In addition to OS and application patching, it supports allowlisting of applications and Just Enough Administration.

Automox 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 operating systems 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: Patch, and Patch & Manage. The Patch 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. Patch & Manage includes all of the same features as Patch but adds the ability to install and enforce software, rules-based patching, Security Assertion Markup Language (SAML) authentication and other capabilities.

GFI LanGuard

GFI LanGuard is a network security tool focusing on 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 (HIPAA, PCI DSS, etc.)

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, which are simply called Small, Medium and Large. 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.

Ivanti Security Controls

Ivanti Security Controls, formerly Patch for Windows, is a versatile patch management product for Windows computers, virtual machines and VM templates. It also supports VMware ESXi hosts, Windows applications and Linux distributions, including Red Hat Enterprise Linux and CentOS. Security Controls has a centralized interface designed to make it easy to scan physical and virtual systems, assess and deploy patches, and schedule remote operations while providing granular privilege management to balance access and security.

Admins can configure Security Controls to automatically run scheduled recurring scans and deploy any missing patches that are detected during the scans. 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 Common Vulnerabilities and Exposures (CVEs) list. It can also show which patches are related to each CVE.
