November Patch Tuesday: How to Sort Through the Patches
Microsoft's November Patch Tuesday addresses 1,252 CVEs, highlighting the need for strategic patching over a blanket
Microsoft's November Patch Tuesday released 1,252 CVEs, a significant increase that makes a "patch everything now" strategy unfeasible. The article emphasizes the need for IT teams to prioritize patching, testing, and mitigation based on exposure and patch reliability. Qualys InstaScan provided early exposure detection, flagging affected assets before Microsoft's release notes were fully available. Approximately 35% of November patches received a low reliability rating from Qualys, underscoring the risk of deploying updates without proper vetting.

The lesson from this incident
Full lessonMicrosoft's November Patch Tuesday released an unprecedented 1,252 CVEs, making indiscriminate 'patch everything immediately' strategies both operationally unfeasible and risky. Approximately 35% of the released patches carried low reliability ratings, meaning blind deployment could introduce instability or new vulnerabilities into production systems. This highlights that effective patch management is not just about speed — it requires prioritization based on exposure, exploitability, and patch quality. Organizations without a structured triage process are forced into reactive, high-risk decisions under time pressure. Tools that surface exposure data before vendor release notes are finalized give security teams a critical head start in protecting the most at-risk assets.
What helps against this
How we list vendors
- Vulnerability scanning and prioritisation
You know which systems are vulnerable, and which ones to fix first.
- Automated patch management
Known holes get closed in days, not months.
- Cyber asset inventory
You cannot patch, monitor or protect the devices, cloud resources and accounts you do not know you have.
