With over 290,000 CVEs and a growing backlog at the NVD, the landscape of vulnerability management is undergoing seismic shifts. Traditional approaches, steeped in reactive patching and endless CVE lists, simply cannot keep pace with modern cyber threats. In this comprehensive guide, we explore why conventional vulnerability management is broken, how EPSS (Exploit Prediction Scoring System) offers a data-driven antidote, and why embracing a Zero Trust architecture might just be the answer for 2025 and beyond.
What’s Wrong with Traditional Vulnerability Management?
For decades, cybersecurity teams have relied on CVE (Common Vulnerabilities and Exposures) and CVSS (Common Vulnerability Scoring System) ratings to set their security priorities. However, several key issues have emerged:
- Volume Overload: With more than 290,000 disclosed vulnerabilities and a backlog of unenriched CVEs, managing each entry is a logistical nightmare.
- Reactive Patching: Security teams are forever chasing after new vulnerabilities, leaving little time to plan and implement proactive countermeasures.
- Limited Exploitation: Despite the vast number of CVEs, only about 6% are ever actively exploited, indicating a misalignment between effort and actual threat.
These flaws force organizations into a reactive mode where even patching hundreds of CVEs doesn’t necessarily reduce the risk of compromise. This is further complicated by internal biases in assessment and bureaucratic delays, as exemplified by the recent CVE backlog reported in 2025.
How Does EPSS Improve CVE Prioritization?
The Exploit Prediction Scoring System (EPSS) was developed to address some of these issues by predicting the likelihood of a vulnerability being exploited in the wild. Rather than trying to patch every vulnerability indiscriminately, EPSS allows security teams to:
- Prioritize Critical Threats: Focus on vulnerabilities that are statistically more likely to be exploited.
- Optimize Resources: Streamline patch management, ensuring that time and manpower are directed where they matter most.
- Complement Traditional Metrics: Use EPSS alongside CVE and CVSS to gain a more nuanced understanding of threat prioritization.

Zero Trust & Attack Surface Reduction: A Better Strategy?
Even with improved scoring systems, the sheer scale of vulnerabilities makes it implausible to patch every potential flaw. Instead, organizations must adopt a strategy focused on reducing the overall attack surface and embracing a Zero Trust security model. Here’s how:
1. Limit Exposure by Reducing the Attack Surface
Streamline your infrastructure to reduce the number of systems exposed to external threats. This includes:
- Identifying and decommissioning unmanaged or unnecessary internet-facing systems.
- Segmenting networks to prevent lateral movement in the event of a breach.
2. Embrace a Zero Trust Architecture
A Zero Trust model assumes that no actor, system, or network segment is inherently trustworthy. By implementing strict access controls and continuous monitoring, you can:
- Minimize access privileges.
- Detect anomalies quickly within the network.
- Enhance overall threat resilience.

Integrating Threat Mitigation and Risk Reduction
Modern vulnerability management must go beyond mere patching. The goal is to fortify overall security through effective threat mitigation and systematic risk reduction:
- Threat Mitigation: Focus on countering active threats using EPSS to guide your priorities. This involves actions such as patching, reconfiguring systems, and applying compensatory controls.
- Risk Reduction: Instead of reacting to every new vulnerability, embed security into your architecture through segmentation, enhanced baseline configurations, and continuous monitoring.
This dual approach not only addresses immediate threats but also builds a resilient digital environment that can adapt as new challenges emerge.
FAQ: Addressing Common Questions on Vulnerability Management
What is EPSS in cybersecurity?
EPSS (Exploit Prediction Scoring System) predicts the likelihood of a vulnerability being exploited in the wild. It complements traditional CVE and CVSS metrics by focusing on real-world threat potential rather than just theoretical risk.
How can organizations reduce the cyber attack surface?
Reducing the cyber attack surface involves minimising unnecessary exposure by decommissioning redundant systems, implementing strict network segmentation, and adhering to a Zero Trust model where access is continuously verified.
Why is traditional vulnerability management considered broken?
The traditional methodology relies heavily on CVEs and CVSS ratings, which often lead to resource-intensive, reactive patching. With an overwhelming number of vulnerabilities and only a fraction being exploited, this approach is inefficient and unsustainable.
Case Study: Security Navigator 2025 Report
Our annual Security Navigator 2025 Report provides a deep dive into these challenges. Based on data collected from extensive VOC (Vulnerability Operation Center) datasets and real-world penetration testing, the report outlines practical steps for optimizing vulnerability management and transitioning to a risk-based approach.
Enhancing Your Security Posture: Actionable Steps
In summary, evolving your vulnerability management strategy involves:
- Re-evaluating Your Patching Priorities: Use EPSS scores to focus on vulnerabilities with the highest likelihood of exploitation.
- Reducing Your Exposure: Systematically shrink your attack surface through network segmentation and decommissioning obsolete systems.
- Adopting a Zero Trust Model: Transform your security architecture by eliminating blind trust and enforcing stringent access controls.
- Investing in Continuous Monitoring: Leverage tools and analytics to gain real-time insights into your network and adjust defenses accordingly.
The transformation from a reactive patchwork of fixes to a coherent, risk-based security strategy is imperative. As cyber threats continue to evolve, so too must our methods of defense.
Conclusion & Call-to-Action
The era of reactive vulnerability management is coming to an end. By integrating EPSS intelligence, embracing Zero Trust architectures, and systematically reducing risk, organizations can break free from the endless CVE treadmill. The future of cybersecurity lies in proactive threat mitigation and a measured reduction in overall exposure.
