The importance of the Vulnerability Operations Center for cybersecurity
Traditional cybersecurity is very focused on detecting and responding to incidents. In other words, it is built around a Security Operations Center (SOC). That in itself is not a bad thing. Read between the lines, though, and that assumes we’re waiting for the threats to come our way. As cyber adversaries evolve their tactics through AI, automated ransomware campaigns and other advanced persistent threats (APTs), taking advanced, proactive measures has never been more critical. Except your SOC team is already drowning in vulnerabilities and quick fixes. How can they even begin to control this?
Today’s ever-deteriorating threat landscape calls for a strategic pivot toward the creation of a Vulnerability Operations Center (VOC) to rethink the fundamental challenges of vulnerability management and cyber resilience.
The Strategic Imperative of the VOC
Traditional strategies are necessary, but painfully insufficient. As an industry, we have been primarily reactive, focusing on the detection and mitigation of immediate threats. This short-term perspective ignores the underlying, ongoing challenge posed by a huge backlog of vulnerabilities, many of which have been known for years but remain unaddressed. Alarmingly, more than 76% of the vulnerabilities currently being exploited by ransomware gangs were discovered more than three years ago. Either the SOC teams don’t care β which we know isn’t true β or they can’t sustain it on their own. It’s time to admit that the biggest problem they face is knowing which handful of threats to focus on during the tidal wave.

The VOC offers a new approach to this challenge, providing a centralized, automated and risk-based approach to vulnerability management. Unlike the SOC, whose primary purpose is to manage incidents and alerts, the VOC is designed to predict and prevent these incidents in the first place. It focuses exclusively on preventing, detecting, analyzing, prioritizing, and remediating security flaws that impact an organization’s unique IT environment. By doing so, VOCs enable organizations to address the much more limited, infinitely more manageable list of vulnerabilities that pose a significant, real threat to their operations and sensitive data.
Linking SOC to VOC: a synergistic approach
The synergy between the SOC and the VOC is essential to creating a comprehensive security framework that not only responds to threats, but also works proactively to prevent them.
The process of connecting SOCs to VOCs starts with CISOs recognizing that patch management is not a standalone task, but a core component of the broader security strategy. A dedicated team or special unit, ideally led by the Chief Information Security Officer (CISO) or other designated security leader, should take the lead in establishing the VOC. This approach underscores the importance of clear guidance from the highest levels of cybersecurity leadership that ensures the VOC is not just an operational unit, but a strategic effort aimed at increasing the organization’s overall cyber resilience.
Setting up a VOC involves leveraging existing vulnerability assessment tools to create a baseline for the current security posture. This first step is critical to understanding the scope and scale of vulnerabilities in the organization’s assets. From this baseline, the team can merge, deduplicate, and normalize vulnerability data to produce a clear, actionable data set. Integrating this data set into the SOC’s Security Information and Event Management (SIEM) systems improves the visibility and context of security events, enabling a more nuanced and informed response to potential threats.
The transition from technical vulnerability assessment to risk-based prioritization is a crucial aspect of the VOC’s function. This includes evaluating the impact of each identified vulnerability on the business, and prioritizing remediation efforts based on this impact. Such a shift allows for a more strategic allocation of resources to focus on vulnerabilities that pose the greatest risk to the organization.
Automation should play a key role in this process, allowing routine vulnerability scanning, alert prioritization and patch deployment to be performed with minimal human intervention. This not only streamlines operations, but also allows analysts to focus on complex tasks that require complex human judgment and expertise.
The VOC provides cybersecurity teams with a comprehensive and systematic approach to vulnerability management, significantly simplifying the process of dealing with an exponentially increasing number of CVEs. The immediate benefits include:
Centralization of vulnerability data: By aggregating and analyzing vulnerability information, VOC provides a unified view that makes life easier for teams identifying and prioritizing critical vulnerabilities.
Automation and streamlining of processes: Using automation tools within the VOC framework accelerates the detection, analysis, and remediation processes. This not only reduces manual workload, but also minimizes the chance of human error, increasing the overall efficiency of vulnerability management.
Risk-based prioritization: By implementing a risk-based approach, teams can focus their efforts on vulnerabilities that pose the greatest risk to the organization, ensuring that resources are allocated effectively and that critical threats are addressed as quickly as possible.
Improved collaboration and communication: The VOC promotes better collaboration between different teams by breaking down silos and ensuring that all relevant stakeholders are aware of the vulnerability management process. This shared understanding improves the organization’s ability to respond quickly and effectively to vulnerabilities.
Ownership and responsibility: Centralizing vulnerability management activities within the VOC framework ensures clear accountability and ownership between teams. This organizational clarity is essential for removing silos and reducing risk because it establishes well-defined roles and responsibilities for vulnerability management, ensuring that all team members understand their role in securing systems and networks.
That’s a lot to digest, but simply put, it’s time to rethink the way we approach vulnerability management. Check out the news β or better yet, reach out to the rest of your cybersecurity team. A VOC reduces the crushing burden of vulnerability management for SOCs and makes life much easier for all security teams. By centralizing operations, automating routine tasks and emphasizing risk-based priorities, VOC improves the organization’s security posture. Linking your SOC to your future VOC creates a seamless flow of actionable information directly to the threat response mechanism.
The end game? Ensuring that your organization’s defenses are both proactive and responsive, for a much more secure and resilient digital environment.
