- Patch scores alone ignore context like network exposure and asset criticality.

- Continuous exposure data replaces static scanning for accurate prioritization.
Prioritize vulnerabilities by actual exploitability and business impact, not by theoretical severity scores. Update your asset context and exposure data continuously to maintain accurate risk rankings.
