The Risks of Ignoring Patch Management & How to Stay Ahead

Every day, we interact with numerous applications, often across different operating systems. Our phones may run on Android, while our laptops may operate on ChromeOS or Windows. Behind each of these applications, there are major companies working tirelessly to enhance the user experience, offer new features, and address any bugs or vulnerabilities. The task of managing updates on our personal devices alone can be challenging. Now, imagine the difficulties faced by IT administrators in large companies who keep every device within their network secure and up to date. It's an intricate task that requires careful attention and diligence. Modern problems require modern solutions. Patch management refers to the process of regularly updating and applying patches, or fixes, to software systems or applications in order to address security vulnerabilities and enhance overall system performance. This process is critical to IT security, as it helps organizations stay ahead of cyber threats and protect sensitive data. However, many organizations still overlook the importance of patch management, putting themselves at significant risk. This article will explore the risks of ignoring patch management and provide best practices for staying ahead of the game.  

The Risks of Ignoring Patch Management

Security vulnerabilities in outdated software

The constant need for evolution and improvement is ingrained in our nature, and this principle applies to our digital lives as well. In the realm of digital evolution, there are two interconnected aspects: as software is utilized and evolves over time, new security threats and attack techniques also emerge. Developers continuously release updates and patches to address these vulnerabilities and improve the security of their software. However, if users neglect to install these updates, their systems remain susceptible to exploitation, as known vulnerabilities persist. Hence, it becomes imperative to prioritize patch management for device security.     

Increased risk of cyber attacks

As the vulnerabilities persist, they serve as entry points for cybercriminals to gain unauthorized access, execute malicious code, or steal sensitive data. Not having proper patch management leaves the door open for attackers who are actively looking for systems that have not implemented the latest patches. They search for specific vulnerabilities that have well-known fixes. By specifically targeting these vulnerabilities, they launch attacks such as injecting malware, conducting phishing campaigns, or taking control of compromised systems.  

Compliance issues

In an enterprise, compliance refers to the act of adhering to all applicable laws and regulations. This includes both internal policies and procedures, as well as external requirements imposed by government agencies, industry organizations, and stakeholders. This regulatory procedure requires mundane everyday patching and updates. For instance, the Payment Card Industry Data Security Standard (PCI DSS) requires organizations that handle credit card information to install patches for critical vulnerabilities within one month of release (Requirement 6.3.3) and to set risk-based timelines for the rest. Consequently, failure to comply with these regulations may result in financial penalties, legal consequences, and damage to the organization's reputation.  

Financial costs of a security breach

A data breach's financial costs can be crippling for an enterprise. Apart from direct costs like incident response and legal fees, the company has to deal with reputational damage, decreased customer retention rates, and the need to restore system infrastructure. According to IBM's Cost of a Data Breach Report 2023, the global average cost of a breach reached $4.45 million that year, a 15.3% rise from 2020. IBM publishes the report every year, so check the latest edition for current figures.  

Staying Ahead of the Game: Best Practices for Patch Management

Automating patch management processes

The diversity of apps, software, operating systems, and regulations your company has to keep up with creates the demand for a management solution that can automatically and rapidly discover and deploy these patches. This enhances efficiency, avoids human error, and keeps patch records consistent for audits, allowing IT admins to save valuable time and focus on other tasks. Patch management automation allows for consistency across all devices and platforms.     

Establishing a patch management policy

Establishing a comprehensive patch management policy is crucial for any enterprise. The policy sets objectives for maintaining a secure environment by assigning clear roles and responsibilities. It also defines the scope by identifying all systems and applications and specifying the extent to which it applies to them. This includes determining whether the policy is applicable to all devices, such as employee workstations, servers, networking devices, and third-party applications. To get started, use our patch management policy template.  

Conducting regular vulnerability assessments

The vulnerability assessment process, as the name suggests, involves constant scanning of devices and networks for potential weaknesses and vulnerabilities. After weaknesses are scanned and identified, patch management uses this information to prioritize the patching process based on the level of risk involved. Together, these two procedures complement each other by creating a flow of constant improvement in your system. This way, you find and fix weaknesses sooner, which shortens the time attackers have to use them.  

Prioritizing critical patches

Not all patches require immediate attention. The severity of the patch plays a significant role in this equation by determining the potential impact of the unaddressed weaknesses. As mentioned previously, the patch management solution adopts a risk-based approach to prioritize patches with the highest vulnerability and exploitability. Moreover, patches that are more relevant to your environment are also prioritized by patch management.  

Tools and Resources for Effective Patch Management

Overview of popular patch management tools and Open-source alternatives

Many patch management solutions in the market strive to offer the best solutions to all enterprises. They range from Microsoft's own services to full endpoint management platforms. Microsoft deprecated WSUS (Windows Server Update Services) in September 2024: it still ships with Windows Server 2025 and still publishes updates, but gets no new features, so many Windows teams are moving to cloud options such as Windows Update for Business, Windows Autopatch, or Azure Update Manager. Most dedicated tools offer automated patch deployment, reporting, and some form of vulnerability scanning. Open-source tools such as Opsi can suit organizations on a limited budget, but check that a project is still actively maintained before you rely on it. For a full comparison on Windows, see our guide to patch management for Windows.  

How trio.so Helps With Patch Management

trio.so is a unified device management platform with OS update management for Windows, macOS, iOS, and Android. From one console, IT admins can schedule operating system updates and enforce them: the Windows Update policy on Windows, declarative device management for macOS and iOS updates, and system update policies on Android. The device inventory shows OS versions, installed apps, and update status for each device, so you can see which devices are behind. You can also deploy apps to managed devices and use app allow and block lists to keep unapproved software off them, and on Windows you can run remote commands and scripts, for example to apply a vendor workaround while a patch is in testing. trio.so's compliance engine checks device settings against framework device controls, and you can export the evidence for your auditors. For details, see the patch management software page.
