Spotlight: Are You Ready For The Patch Wave?

May - June 2026

 

 

Are you prepared for the patch wave? why regularly patching your systems and software is more important than ever before

For many years, cyber security teams have followed a familiar rhythm; identify vulnerabilities, test updates, deploy patches, and move on to the next maintenance cycle. Today, that rhythm has changed dramatically.

We are entering what many cyber security professionals describe as a 'patch wave'. A period where organisations are facing an unprecedented volume of software vulnerabilities, security updates, and remediation requirements. The driving force behind this change is not simply the growing number of cyber threats. Increasingly, it is the rapid development and adoption of Artificial Intelligence (AI).

The same technology helping organisations innovate faster is also fundamentally changing how vulnerabilities are discovered, exploited, and patched. AI-assisted development tools have transformed software engineering. Developers can now generate code faster than ever before, accelerating innovation and reducing development timelines.

However, faster development means:

  • More applications being created
  • More code being written
  • More dependencies and open-source components being used
  • More opportunities for security flaws to emerge

At the same time, AI is enabling security researchers and threat actors alike to analyse code at a scale that was previously impossible. Microsoft recently warned that advanced AI models are capable of autonomously identifying weaknesses, linking vulnerabilities together, and producing proof-of-concept exploits, significantly reducing the time between vulnerability discovery and exploitation. What previously took weeks can now take minutes.

The result? Vulnerabilities are being discovered faster than organisations can traditionally patch them.

 

The Time Between Vulnerability Discovery to Exploitation is Decreasing

Historically, organisations often had weeks or months to respond after a vulnerability became public. That window is shrinking.

Security experts are reporting that AI-driven vulnerability analysis is finding software weaknesses "at industrial scale”, accelerating both defensive research and offensive exploitation. This means that once a patch is released, attackers can quickly analyse the update, identify what was fixed, and target organisations that have not yet applied the patch. This creates significant risk for organisations with infrequent or irregular patch cycles.

Vulnerability disclosures in 2026 have already reached record levels, with AI-assisted discovery identified as a major contributor to the surge. Furthermore, a number of publicly available AI models are now capable of producing the code and processes to exploit these vulnerabilities.

 

Why Attackers Love Unpatched Systems

Cyber criminals rarely need sophisticated zero-day exploits when unpatched systems remain readily available.

Many ransomware groups actively scan the internet for organisations that have failed to apply publicly available updates. Once a vulnerability becomes known and a patch is released, attackers often assume that:

  • Some organisations will delay patching
  • Legacy systems may be too challenging to update quickly
  • Operational concerns will slow remediation efforts

In effect, every unpatched system becomes a potential target. This is one reason why the United States Cybersecurity and Infrastructure Security Agency (CISA) maintains its Known Exploited Vulnerabilities (KEV) catalogue, highlighting vulnerabilities that are already being exploited in real-world attacks and should be prioritised immediately.

 

The New Reality: Patching Is a Business Risk Function

Patching is no longer simply an IT maintenance activity. It is now a core cyber resilience function.

Boards, executives, and risk owners should view patch management as an essential control that helps:

  • Protect business operations
  • Reduce ransomware exposure
  • Safeguard customer and organisational data
  • Maintain regulatory compliance
  • Improve organisational resilience

 

How Organisations Can Prepare for the Patch Wave

To keep pace with the accelerating patch cycle, organisations should:

1. Know What You Own - Maintain a complete and accurate asset inventory. You cannot patch systems that you do not know exist.

2. Prioritise Based on Risk - Not every vulnerability requires immediate action.

Focus on:

  • Internet-facing systems
  • Critical business applications
  • Vulnerabilities listed in CISA's KEV catalogue
  • High-likelihood exploitation scenarios

3. Reduce Patch Latency - The shorter the interval, the lower the exposure.

Measure the time between:

  • Patch release
  • Risk assessment
  • Deployment

4. Test and Automate - Automated patch deployment and vulnerability management tools can significantly reduce administrative burden and improve consistency.

5. Build Security into Procurement - Ensure suppliers and service providers maintain robust patch management processes as part of contractual requirements.

 

Conclusion

Artificial intelligence is accelerating every aspect of the cyber security landscape. It is helping developers create software faster, researchers uncover vulnerabilities sooner, and defenders identify and address weaknesses more effectively. However, these advantages are not limited to the good actors. The same capabilities are enabling cyber criminals to find, exploit, and scale attacks against vulnerabilities at an unprecedented pace.

As vulnerability discovery accelerates, organisations that treat patching as a routine maintenance task will increasingly struggle to keep pace. Those that view patch management as a strategic cyber resilience capability will be far better positioned to withstand the growing volume of threats.
