Understanding the full lifecycle means more than just running a scanner and patching some systems. Here’s a breakdown of each phase, designed to help you build, test, or review your own program.
Step 1. Preparation and planning
You can’t fix what you don’t know exists.
Identify stakeholders and assign clear roles (security, IT ops, business leaders).
Gather the right resources (tools, people, budgets).
Set up metrics for success (patching rate, mean time to remediate, vulnerability age).
Develop criteria for classifying and handling different types of vulnerabilities.
Cyber pro tip: Document everything. You’ll thank yourself at audit time.
Step 2. Asset discovery and vulnerability identification
You’d be shocked how many companies don’t have a true map of their IT assets.
Build an up-to-date inventory (servers, laptops, cloud services, IoT devices…)
Run routine vulnerability scans to search for weaknesses.
Use penetration tests, config reviews, and manual checks for deeper insight.
Include “Shadow IT," the rogue laptop or forgotten web app someone spun up without telling security.
Step 3. Vulnerability assessment and prioritization
Not all vulnerabilities are created equal. If everything’s “high priority,” nothing is.
Assess each finding’s business impact, likelihood of exploitation, and exposure.
Use risk scoring frameworks like CVSS (Common Vulnerability Scoring System).
Factor in how easy a vulnerability is to fix, and recent threat intelligence.
Prioritize fixes based on real business risk, not just the severity number.
Thousands of “critical” alerts can overwhelm teams. Set up a clear, unbiased method for separating “fix now” from “fix later.”
Step 4. Vulnerability remediation or mitigation
This is where the rubber meets the road.
Remediation: Patch or eliminate the vulnerability.
Mitigation: Reduce risk (add firewall rules, more monitoring) if you can’t patch right away.
Acceptance: Decide not to fix a low-risk issue (with proper documentation).
Good coordination between IT and security here saves tons of time.
Step 5. Verification and monitoring
Trust, but verify.
Double-check fixes worked (re-run scans or tests).
Use continuous monitoring to spot new vulnerabilities as they emerge.
Catch anything that slipped through, or that comes back (“regressions”).

Step 6. Reporting and continuous improvement
What gets measured gets managed.
Document actions taken, results, and any lessons learned.
Share findings with leadership, auditors, and front-line teams in language they can relate to.
Review what worked, what didn’t, and iterate for even sharper results next cycle.
Remember: The cycle loops forever. VML is only as good as your follow-through and ability to adapt.
