What is so special about the second Tuesday of every month in IT? Patch Tuesday is the day Microsoft and other leading tech companies release security updates and bug fixes.
Managing patches takes time and requires resources. For managed service providers (MSPs) and IT departments, Patch Tuesday is a built-in checkpoint—a chance to apply critical fixes and updates to address vulnerabilities and keep systems secure. Since it happens on a set schedule, many IT professionals opt to mark it on their calendars and plan ahead.
Some patches may be simple fixes, while others may be more in-depth updates. But the predictability of Patch Tuesday helps IT teams stay organized and keep critical fixes from slipping through the cracks.
Key takeaways
- Patch Tuesday began in 2003 when Microsoft decided to release fixes and updates on a consistent monthly schedule.
- The day has become an industry standard that supports greater efficiency, security, and compliance across IT environments.
- Planning for Patch Tuesday and following best practices for patch management helps IT prioritize critical security updates and protect against breaches and attacks.
- Software solutions streamline and enhance patch management with automation, centralized control, and reporting.
When is Patch Tuesday?
While the exact date changes, Patch Tuesday always falls on the second Tuesday of the month. Microsoft and other tech companies use this day to release security updates, bug fixes, and sometimes new product features—all in one go.
Microsoft’s Patch Tuesday fixes are usually released at 10 a.m. Pacific time. Other major software vendors, including Adobe and Oracle, have followed Microsoft’s example and also release updates on Patch Tuesday. This structured approach helps MSPs and internal IT teams alike maintain performance and security across a diverse range of products and applications.
The history of Patch Tuesday
Microsoft Patch Tuesday didn’t happen by accident. Previously, patches and updates were released inconsistently, forcing IT teams to interrupt their schedules to address them. Then, in 2002, a series of critical security breaches damaged systems around the world, forcing action. While patches were available for some of these vulnerabilities, many organizations hadn’t implemented them in time, leaving them open to attacks.
In the aftermath, Microsoft changed its approach to security. October 2003 marked the first official Patch Tuesday.The timing was carefully chosen: Releasing patches and updates early in the week gave administrators time to prepare for them and then address issues related to the patches before the end of the week.
Over time, Patch Tuesday has become an industry standard, reinforcing a proactive security mindset. With many major tech companies following this model, IT techs are positioned to stay ahead of vulnerabilities and maintain optimal system performance.
Why Patch Tuesday is important for cybersecurity
Because it’s been so effective, Patch Tuesday has become a critical part of organizational cybersecurity. IT teams can strengthen security and reduce the risk of data breaches for both clients and their own businesses by incorporating Patch Tuesday updates into their processes.
Some of the Patch Tuesday benefits include:
- Consistent cadence. The monthly cadence enables IT teams to implement efficient workflows for patch deployment and ensure they have time to address any unexpected issues.
- Greater efficiency. Releasing multiple patches at the same time allows techs to quickly assess which patches address the most pressing vulnerabilities and apply them across all systems at once, rather than dealing with them individually
- Less risk of overlooking important updates. The structured release cycle means IT teams are less likely to miss or delay critical patches, ensuring timely updates across all managed systems.
- Reduced downtime. Knowing when updates will drop enables IT to plan implementation during nonpeak hours, minimizing disruptions to business operations if systems need to be offline or capacity will be affected.
- Simplified compliance. The regular nature of Patch Tuesday simplifies the process of tracking and documenting patch deployment. Organizations can generate reports showing the consistent application of updates. This helps IT teams meet industry regulations and cybersecurity insurance requirements for themselves and their clients.
- Less risk of zero-day vulnerabilities. A consistent schedule allows for more immediate patch implementation. This reduces the chances that hackers and cybercriminals will be able to exploit the vulnerabilities the patches fix—something explained in more detail in the next section.
Patch Tuesday and Exploit Wednesday
An unintended consequence of Patch Tuesday is the rise of Exploit Wednesday. This refers to the phenomenon of cybercriminals attempting to identify the vulnerabilities the patches released on Tuesday are meant to fix. They then try to exploit them before IT teams can implement the updates.
This puts IT teams under pressure to roll out updates quickly and efficiently. Automated patch management solutions help streamline the process, make sure patches are applied correctly, and quickly detect and resolve any deployment issues.
Best practices for patch management
Patch Tuesday can feel like the floodgates opening as Microsoft and other vendors release a wave of security updates. Techs are left to sift through them to figure out what’s critical, what’s recommended, and what’s optional.
Patch management best practices can help maintain security, reduce risk, and ensure business continuity for clients and end users. These guidelines can help ensure patches are deployed efficiently, effectively, and with minimal disruption.
- Create a workflow to manage patch releases. Define a step-by-step process for handling patches that includes assessment, testing, prioritization, deployment, and verification.
- Ensure proper backups have been completed. Organizations should ensure systems and data are backed up before Patch Tuesday to minimize the damage in case of corruption from a patch installation. Offerings like ConnectWise’s NOC Services can also support here through providing patch testing.
- Take advantage of patching resources. Microsoft’s Patch Tuesday bulletins, security newsletters, and community discussions can help IT teams stay ahead of potential issues.
- Prioritize patches based on risk. Focus first on critical security updates before moving to quality or feature updates.
- Test patches prior to deployment. Use a staging environment to test updates before rolling them out to production systems.
- Take advantage of patch automation. Leverage automation tools to schedule deployments, enforce policies, and reduce human error.
- Maintain an inventory of all assets. Keep an updated inventory of devices, operating systems, and software versions to ensure comprehensive coverage.
- Monitor and verify patch deployment. Track patch completion rates, troubleshoot failed updates, and ensure all systems are fully protected.
- Monitor privileged sessions. Keep logs and audit activity to prevent unauthorized actions during the process.
- Manage the identity lifecycle. Controlling and securing user and system identities, including ensuring proper provisioning and de-provisioning of accounts, minimizing risks.
