The Shift from Vulnerability to Exposure Management

Why Traditional Vulnerability Management is Not Enough

Ever since Gartner® introduced its Continuous Threat Exposure Management (CTEM) program, the cybersecurity industry has started to rethink “proactive” strategies, moving from traditional vulnerability management to a more comprehensive approach known as exposure management. While vulnerability management has traditionally focused on identifying and patching common vulnerabilities and exposures (CVEs), exposure management takes a broader approach, evaluating an organization’s entire risk landscape from an attacker’s perspective. 

Exposure Management vs. Vulnerability Management: Why the Difference Matters

The key distinction between vulnerability management and exposure management is the approach to identifying risk. Vulnerability management focuses primarily on scanning for and remediating CVEs, publicly known security vulnerabilities in software and hardware that attackers might exploit. In contrast, exposure management aligns more closely with an attacker’s perspective, targeting the most critical and potentially damaging security gaps unique to your organization.

By adopting an attacker’s viewpoint, exposure management enables organizations to continuously validate their controls against the most pressing vulnerabilities and security gaps to determine true threat exploitability. This proactive approach helps organizations prioritize resources where they are needed most.

Benefits of Exposure Management Software

Exposure management platforms enable you to keep your organization safe and stay one step ahead of an attack. The Cymulate 2024 State of Exposure Management & Security Validation report proves the importance of adopting an exposure management strategy that considers the following:

• Source of exposure – vulnerability, misconfiguration, control gap, etc. 
• Business impact – critical assets, data, and infrastructure at risk 
• External threat activity – known or active attacks that target the exposure 
• Attack feasibility – effectiveness of mitigating controls to prevent a breach if attacked 

Prioritize the Biggest Weaknesses, Not the Most Severe CVEs

Data from the Cymulate 2024 report highlights a significant difference between assessed vulnerabilities and those that pose an actual threat. Across simulations conducted with over 500 global customers, Cymulate observed that while certain CVEs were frequently assessed, they were not necessarily the most exploited. This finding underscores the value of exposure management, prioritizing vulnerabilities based on their exploitability in a given environment rather than severity scores alone.

*Average Control Effectiveness – The average control effectiveness rate reported is based on the security controls’ ability to recognize known Indicators of Compromise (IoCs). The Immediate Threats module of Cymulate BAS does not run active code like other Cymulate BAS modules. The other modules in Cymulate BAS do assess the effectiveness of behavioral detection and monitoring solutions in stopping executions in progress. In the case of threats with CVEs, the results do not indicate the presence of the vulnerability.

Interestingly, none of the CVEs most frequently assessed make the list of the most successfully exploited. This disconnect highlights a nuance in exposure management: It’s not only the identification of critical or high vulnerabilities that matters but whether they are exploitable within an organization’s unique environment. The report illustrates scenarios where vulnerabilities with high severity scores were effectively neutralized by compensating controls, preventing successful exploitation.

Exposure Management: A Holistic View of Security Posture

Exposure management offers a more comprehensive view of your organization’s security posture than vulnerability management alone. It helps allocate security resources more strategically, focusing on real risks rather than theoretical ones. For instance, while a high-severity vulnerability in a critical system warrants immediate attention, a similar vulnerability in a less critical area with effective compensating controls might be deprioritized.

Additionally, exposure management goes beyond vulnerabilities to evaluate misconfigurations and control gaps, providing a realistic view of your organization’s riskiest exposures.

The Cymulate platform continuously assesses and validates the attack surface from an attacker’s perspective, simulating potential attack paths to keep defenses agile and responsive.

Gain Context for Better Security Decisions with Cymulate

Exposure management signals a shift toward a dynamic, proactive cybersecurity approach emphasizing risk assessment and business impact over a purely vulnerability-centric focus. By prioritizing the most significant weaknesses rather than focusing solely on CVEs, organizations can allocate resources more effectively, protecting essential digital assets and maintaining business continuity.

The Cymulate 2024 State of Exposure Management & Security Validation report illustrates the urgency of adopting an exposure management strategy to stay ahead of evolving threats. For organizations looking to enhance their cybersecurity strategy, exposure management vs. vulnerability management is critical in achieving a robust, forward-looking defense posture.
