You already know about Black Friday and Cyber Monday. But Patch Tuesday is more significant for the tech community, as it's when Microsoft and other major companies drop their latest security updates and bug fixes.

And just like Black Friday and Cyber Monday, the best part about Patch Tuesday is that you can plan ahead for it. IT pros can mark their calendars, prep their teams, and make sure they have some additional time to handle any complex updates that need more careful testing. In this blog, we'll explore Patch Tuesday in more detail and explain how to use it to your advantage. 

When Is Patch Tuesday?

Patch Tuesday is always the second Tuesday of every month. But apart from Microsoft, which tends to kick things off at 10:00 a.m. Pacific Time, a few other large software developers like Adobe and Oracle have synced their patching schedules and will release their updates at different times throughout the day. 

Patch Tuesday's Origin Story

If you think getting security updates is messy now, you really wouldn't have enjoyed the early 2000s. Getting security updates was a mess. Microsoft would release patches whenever they were ready, with no schedule, no warning, just random updates dropping throughout the month.

For IT teams trying to keep systems secure, it caused a lot of chaos. You'd never know when the next critical patch would arrive or how to plan for it. And when it hit, you sometimes had to rearrange your day. 

Then, in 2003, Microsoft's Security Response Center (MSRC) had a simple but brilliant idea: what if we released all our security updates on the same day every month? Security Release Manager Craig Gehre was tasked with making that vision a reality. The team shifted from their "ship when ready" approach to a predictable monthly schedule, and Patch Tuesday was born.

Patch Tuesday's Ripple Effect

Patch Tuesday wasn't the only change Microsoft made. The company also created a single location where people could get all the details about each month's security releases, so customers wouldn't have to go digging through haystacks of Knowledge Base articles. 

Patch Tuesday's success didn't go unnoticed. Other major software companies started moving to similar monthly schedules, and a few hardware vendors (AMD and Intel) also jumped on board. In doing so, the industry became more collaborative vs. strictly competitive, and created a more unified front against cyber threats. 

The Unfortunate Rise of Exploit Wednesday

Patch Tuesday offers a number of convenient advantages for IT pros, but cybercriminals also quickly figured out how to use it for their own benefit. And yes, this is basically why we can't have nice things. 

On Patch Tuesday, a number of important security updates are released to fix vulnerabilities that software developers have discovered. And so hackers start using those patch releases to reverse-engineer those patches to discover vulnerabilities that they could exploit ... that is, if they can figure it out before IT pros around the world apply the patch. 

Exploit Wednesday has created a ticking time bomb for IT teams. They need to move fast, but they also can't afford to mess up and break systems with a rushed patch deployment. And that's why automated patch management tools are lifesavers. They help IT teams roll out updates quickly and correctly, while keeping an eye out for any problems that pop up during the process. 

Patch Management Tips for IT Teams Racing Against the Clock

When Patch Tuesday hits, Microsoft and other vendors will often dump dozens of updates at once, and you're left figuring out what needs immediate attention versus what can wait.

Here's how to stay one step ahead of the cybercriminals:

1. Get Organized Before the Chaos

Patch Tuesday can feel like drinking from a fire hose, but it doesn't have to be that way. A little planning can go a long way.

Build a formal patch management policy

Having everything documented means your team follows the same process every time, no matter who's handling it. Your policy should define roles and responsibilities, establish approval processes for different types of patches, and set clear timelines for deployment. This documentation becomes especially valuable when you're dealing with emergency patches or when team members are out of the office. 

Create a step-by-step workflow

When you're under pressure, having a clear roadmap helps prevent mistakes and ensures nothing gets skipped. Ideally, your workflow should include decision points for handling patches based on priority. For example, critical patches might bypass some testing phases, while routine updates follow the full process. Document who needs to approve what, how long each phase should take, and what triggers an escalation to management.

Keep an updated inventory

You can't patch what you don't know other employees are using! Maintain a current list of all devices, operating systems, and software versions across your environment. This inventory should include details like patch levels, system criticality, and maintenance windows. Many IT teams discover shadow IT only when a major vulnerability hits. Don't let that be you. 

2. Protect Your Data First

Patches aren't always perfect! Even well-tested updates from major vendors like Microsoft can sometimes cause unexpected issues, including system crashes and compatibility issues.

Back everything up beforehand

Back up your systems and data before Patch Tuesday. If something goes wrong, you'll be glad you did. Also, make sure to test your backup restoration process regularly. A backup you can't actually restore from isn't helpful. 

Test patches in a staging environment

Test updates on similar systems first to catch any issues. Your staging environment should mirror your production setup as closely as possible, including the same operating systems, applications, and configurations. That way, you can catch any problems before they affect your users.

When possible, document any issues you find as well as their workarounds. What you find could be valuable for future patch cycles.

3. Work Smarter, Not Harder

You can't do everything at once. If you try to give equal attention to every single update, you'll end up getting frustrated. You could also miss a critical patch! Make sure you focus more of your time and attention where it matters most.

Focus on the critical stuff first

You'll want to prioritize security patches over feature updates. Critical security updates should typically be deployed ASAP, while lower-priority patches can follow your standard maintenance schedule.

Generally speaking, you should pay special attention to patches for internet-facing systems, domain controllers, and other high-value targets that attackers commonly exploit. 

Use automation tools

When possible, let technology handle the routine deployments and scheduling so you have more time for more complex issues. Automated patch management systems can handle tasks like downloading patches, scheduling deployments, and generating compliance reports. They can also automatically reboot systems when needed and verify that patches are installed correctly. 

Tap into available resources

Microsoft's security bulletins and other online cybersecurity community discussions can give you early warnings about potential problems. Don't reinvent the wheel—learn from others' experiences and challenges.

4. Follow Through

Once you deploy patches, you're done, right? Not so fast. You still need to verify they actually worked and close any security gaps that might have been missed.

Monitor your deployment progress

Track completion rates, fix failed updates, and make sure nothing slipped through the cracks. If you can, set up alerts for failed installations so you can address issues quickly before they become security gaps. 

Keep logs of everything

Your logs should capture who deployed what patches, when they were installed, and any issues that occurred during the process. This documentation is especially helpful if you need to roll back changes or investigate security incidents later. 

Remember, the goal isn't just to apply patches. It's to apply them faster than the bad guys can figure out how to exploit the vulnerabilities you're fixing.

Should You Consider Patch Management as a Service?

Small to medium-sized organizations often lack the dedicated expertise and infrastructure needed to properly test, deploy, and verify patches quickly. Bottom line, if Patch Tuesday consistently creates chaos for your IT team, or if you're struggling with complex compliance requirements and limited testing resources, it might be time to consider outsourcing this and other IT tasks. 

A managed service provider will bring specialized expertise, daytime and after-hours capabilities, and sophisticated testing environments that are unsustainable for most smaller organizations. And if the cost of a failed patch or missed vulnerability could significantly impact your business, the investment in professional patch management (as part of a managed IT service offering) can help pay for itself.
