Vulnerability Management: the real challenge isn't finding flaws — it's prioritising them

The biggest challenge in Vulnerability Management isn't finding vulnerabilities. It's knowing which ones to fix first.


Between daily scans, vulnerability reports and the hundreds of CVEs released each week, it's easy to end up with a backlog you can't possibly work through.


👉 The reality? Most teams aren't short on information. They're short on prioritisation.

🚨1. Start with actively exploited vulnerabilities

👉 The first resource I check is the CISA KEV (Known Exploited Vulnerabilities Catalog).

  • It lists vulnerabilities already exploited in the real world
  • A CVE in the KEV deserves immediate attention
  • It's the most reliable signal of concrete risk

📊2. Don't stop at the CVSS score

👉 CVSS measures theoretical severity; EPSS measures the probability of near-term exploitation.

  • Combine high CVSS + high EPSS + Internet exposure
  • Those vulnerabilities naturally rise to the top of the list
  • Context often matters more than the score itself

🗂️3. Know your estate before you scan

👉 An incomplete asset inventory creates noise and wastes time.

  • Ask yourself: does this technology actually exist in my environment?
  • No point mobilising a team on a CVE with no affected asset
  • A reliable inventory focuses effort on what's real

⚙️4. Automate recurring patches

👉 The simplest vulnerabilities are often the ones that pile up.

  • Browsers, PDF readers, system components, standard patches
  • Automation sharply reduces operational load
  • Teams can then focus on critical risks

💡 The key takeaway

Reduce exposure, don't just accumulate detections

Cybersecurity doesn't reward the organisations that detect the most vulnerabilities. It rewards those that reduce their risk exposure as fast as possible.

« Most teams aren't short on information: they're short on prioritisation. »
  • Prioritisation beats raw detection volume
  • Remediation speed is the key metric
  • Business risk drives the final decision

🧪 A small exercise this week

Open your vulnerability dashboard and identify:

  • 1The CVEs listed in the CISA KEV
  • 2Those with the highest EPSS score
  • 3The assets actually exposed to the Internet
  • 4You'll likely have your priority list for the coming days

🧠 Over to you

Prioritisation isn't a luxury: it's what separates an overwhelmed team from one that controls its exposure.

KEV for real exploitation, EPSS for probability, inventory for scope, automation for volume: four complementary angles.

What is your main prioritisation criterion today? CVSS · EPSS · KEV · Business criticality of assets?
