13/05/2025

Risk-Based Vulnerability Management

Given the constant increase in cyber threats, risk-based vulnerability management has become indispensable for CISOs and IT managers. It’s not enough to just list technical flaws; it’s essential to understand which vulnerabilities pose real risks, prioritizing those that can have the greatest impact on the organization’s critical assets.

While there are over 185,000 known vulnerabilities, only a small portion is actually exploited. This reinforces the need to look beyond volume and focus on reducing exposure to critical threats, aligning security with business goals and continuity.

This article presents the central concepts of risk-based management, based on international standards such as ISO 27001, NIST SP 800-30, CVSS, and CIS Controls. It will also show how platforms like Qualys, especially the VMDR, Policy Compliance, and Threat Protection modules, allow for the automation and strengthening of this model, prioritizing intelligently and quickly.

What is Risk-Based Vulnerability Management

Vulnerability management is an ongoing process of identifying, analyzing, prioritizing, and remediating flaws that could be exploited by threats. When risk-oriented, it goes beyond technical severity by considering the likelihood of exploitation and its impact on the business (such as financial loss, service disruption, or compliance violation).

Unlike traditional approaches, which treat all flaws as equally critical, risk-based management incorporates business context and threat intelligence. Questions such as which systems are most critical, which flaws are under active attack, and which recent threats increase exposure, guide the prioritization of what truly matters.

More than finding vulnerabilities, this approach aims to reduce cybersecurity risk efficiently by applying the organization’s limited resources to actions that provide the greatest return in protection and resilience.

International Standards and Best Practices

Various internationally recognized standards and frameworks guide the incorporation of risk assessment into the vulnerability management process. Among the most relevant, the following stand out:

ISO/IEC 27001 and ISO 27002

ISO 27001 requires periodic risk assessments and the structured treatment of information security threats. The 2022 version explicitly introduced the control “Management of Technical Vulnerabilities” (Annex A 8.8), which addresses the identification of vulnerabilities in IT assets, risk analysis, and the implementation of corrective measures.

This control reinforces the importance of maintaining an updated inventory of assets, continuously monitoring threats, and adopting a proactive mitigation stance. In summary, ISO standards highlight that vulnerabilities must be addressed within a comprehensive risk management process for the organization.

NIST SP 800-30 – Risk Management Guide

This publication by NIST establishes that risk results from the combination of threat, vulnerability, and impact. The guide advises identifying relevant scenarios (e.g., known exploits or malicious agents with specific interests), mapping exploitable vulnerabilities in these contexts, and estimating the likelihood and potential impact.

Applied to vulnerability management, this methodology allows for the prioritization of fixes based on the combined analysis of criticality and the possibility of exploitation, aligning with the Risk Management Framework (RMF) from NIST.

CVSS – Common Vulnerability Scoring System

CVSS is widely adopted to measure the technical severity of vulnerabilities, assigning a score from 0 to 10 based on base, temporal, and environmental metrics. However, it does not directly measure business risk.

A flaw with a CVSS score of 8.0 in an isolated system may represent less risk than one with a 7.0 in a critical and exposed server. Therefore, best practices recommend using CVSS as a starting point, complementing it with organizational context, threat intelligence, and asset criticality – something tools like Qualys VMDR already do by adjusting risk scores more in line with the organization’s reality.

CIS Controls – Center for Internet Security

The CIS Critical Controls represent a prioritized set of best practices in cybersecurity. Control 7 (Continuous Vulnerability Management) from version 8 focuses on the continuous detection of vulnerabilities, their contextual evaluation, and rapid remediation. It recommends regular scans, monitoring of reliable sources for new flaws, and immediate actions to mitigate risks before exploitation.

The controls also encourage the use of threat intelligence to adjust prioritization. Additionally, complementary controls such as Control 1 and 2 (hardware/software inventory), Control 4 (configuration management), and Control 16 (privileged account control) are essential to sustain a solid risk posture, ensuring visibility, system hardening, and minimizing the attack surface.

Together, these standards and frameworks provide a solid foundation: inventorying assets and vulnerabilities, assessing risks, prioritizing actions, and continuously monitoring. Adherence to standards such as ISO 27001 and NIST, combined with the use of metrics like CVSS and CIS controls, helps align vulnerability management with governance expectations and international practices, giving managers confidence that they are following recognized guidelines.

Security Platforms Supporting Risk-Based Management

Specialized tools play a critical role in enabling risk-based vulnerability management at scale. One of the leading platforms in this area is the Qualys Cloud Platform, which offers an integrated set of security applications.

In particular, the following modules focused on vulnerabilities, compliance, and threats stand out, supporting all stages of the risk-based process:

Vulnerability Management, Detection and Response (VMDR)

This is the main vulnerability management module in Qualys. VMDR covers the complete cycle: asset discovery, vulnerability scanning/assessment, risk-based prioritization, and response (e.g., patch application or mitigation).

Unlike traditional scanners, Qualys VMDR incorporates real-time threat intelligence (from over 25 sources of threat indicators) and business context data to assign reliable risk scores (TruRisk™) to each vulnerability and asset. These scores consider factors such as whether an exploit is active or malware is exploiting the vulnerability, whether the asset is exposed externally, and whether it is critical to the business.

As a result, VMDR automatically prioritizes vulnerabilities that present the greatest material risk to the organization, reducing up to 85% of the vulnerabilities classified as critical compared to prioritization based solely on CVSS. The module offers unified dashboards and reports that make it easier to communicate risk to both technical teams and executives, integrating with ITSM tools (such as ServiceNow) for patch management.

Additionally, the “Response” in VMDR indicates integrated remediation resources, such as Qualys Patch Management, which enables patching actions directly through the platform, automating patching workflows, and eliminating risks up to 60% faster.

Risk-Base Prioritization and Remediation with Qualys VMDR

Risk-based vulnerability management follows a continuous five-step cycle, supported by tools like Qualys VMDR, which automate and integrate each phase with contextual intelligence:

Inventory and Exposure: The first step is to identify all of the organization’s assets—physical, virtual, in the cloud, and external—mapping their exposure (e.g., external access or presence of sensitive data). Tools like CSAM and EASM ensure complete visibility, which is essential for assessing real risk.
Risk Contextualization: To transform technical data into real risks, context is added: the criticality of each asset (via tags, CMDB, etc.) and threat intelligence (e.g., active exploits and ransomware campaigns). VMDR uses this data to highlight what truly needs immediate attention.
Continuous Assessment: Vulnerability detection is performed regularly through scheduled scans and agents on endpoints. This assessment covers both software flaws and misconfigurations (via Policy Compliance), ensuring that the environment remains up to date and secure.
Prioritization and Remediation: The core of the process is prioritizing what matters most. Qualys calculates the TruRisk Score for each flaw, combining severity, context, and threats. Based on this, the organization can focus on the 5–15% of vulnerabilities that really put the business at risk. Remediation can be automated using resources like Patch Management and integrations with ITSM systems, speeding up response while adhering to defined SLAs.
Monitoring and Continuous Improvement: Dashboards and reports allow monitoring of indicators like global risk, remediation time, and compliance progress. This data guides strategic and operational decisions, allowing for continuous adjustments, periodic review meetings, and agile responses to new threats in a constantly changing environment.

iT.eam Vulnerability Management Service: Differentiation and Complement

Although technological platforms like Qualys are powerful, the maximum effectiveness of risk-oriented vulnerability management is achieved when human intelligence and specialized processes are added to the tool’s use. This is where iT.eam’s Vulnerability Management Service stands out as a key differentiator. iT.eam, acting as a strategic security partner, offers a managed service that complements and enhances the use of platforms like Qualys for its clients.

In practice, iT.eam’s service assumes the continuous operation of the vulnerability cycle, from the optimized configuration of scans to the follow-up of remediation efforts, relieving the burden on internal teams. iT.eam specialists bring consolidated experience in analyzing and interpreting findings from scanners like Qualys VMDR, applying the client’s business context in a more refined way.

For example, upon receiving a report with thousands of vulnerabilities, the iT.eam team helps quickly identify which of them represent critical risks to the specific business objectives of that client, considering nuances that the tool alone may not recognize (such as operational restrictions, legacy system compositions, application dependencies, industry regulatory requirements, etc.).

One clear benefit is customized prioritization: while Qualys provides standard prioritization based on global risk metrics, iT.eam adjusts this prioritization to the organization’s reality. For instance, if an outdated application cannot be immediately updated due to compatibility reasons, the managed service guides compensatory controls and recalculates the residual risk in a way that is understandable to managers.

Additionally, iT.eam proactively monitors the client’s environment, using the Qualys platform integrated with its SOC (Security Operations Center) processes. Thus, if a new critical threat emerges (e.g., an active zero-day vulnerability), the team can quickly assess the client’s exposure via Qualys and issue actionable alerts, recommending urgent mitigation steps or even executing temporary adjustments (such as network isolations) as agreed upon.

Another valuable contribution is in the workflow management of remediation. iT.eam acts as a facilitator between the client’s Security and IT departments, helping to translate vulnerability reports into clear action plans. This includes opening and assigning tickets to responsible parties, tracking remediation deadlines, and verifying if remediations were effective (by re-scanning via Qualys).

A dedicated team ensures that no critical vulnerability “slips through the cracks” due to communication failure or lack of follow-up. Essentially, the managed service ensures discipline and consistency in the correction process—an ongoing challenge for many organizations with other daily operational priorities.

Moreover, iT.eam brings expertise in compliance and governance, aligning vulnerability management with the relevant frameworks for the client. For example, if the company needs to meet PCI-DSS, HIPAA, LGPD, or other standards, the service focuses on vulnerabilities and configurations whose correction also supports these obligations, combining risk and compliance efforts.

iT.eam also provides periodic executive reports, demonstrating in business language the gains achieved (such as reduced exposure, SLA compliance, risk trends over time). This complements Qualys’ technical dashboards with a strategic view for senior management and boards.

In summary, iT.eam’s Vulnerability Management Service maximizes the value of scanning tools like Qualys, providing the layer of intelligence, tailored prioritization, and coordinated execution that is often missing to transform vulnerability data into real risk reduction. This hybrid model (leading tool + specialized service) gives the CISO the best of both worlds: cutting-edge technology operated by experts, resulting in a strengthened security posture aligned with business objectives, without burdening internal teams.

Conclusion

Adopting risk-based vulnerability management is a strategic evolution in cybersecurity. Rather than treating all flaws equally, this approach focuses on those that truly threaten the organization’s critical assets and processes. This allows CISOs and IT managers to allocate efforts where they have the greatest impact, preventing incidents more efficiently.

Global standards such as ISO 27001 and NIST, combined with modern platforms like Qualys VMDR, make this approach feasible and scalable, integrating asset discovery, threat intelligence, compliance, and remediation into a single workflow. Automation helps, but the real differentiator lies in the combination of technology, solid processes, and skilled people.

In this context, iT.eam’s service enhances the benefits of technology, turning data into action with specialized analysis, remediation support, and a focus on real risk.

Ultimately, it’s about changing the mindset: less reactivity and more strategic focus. Instead of trying to fix everything, the organization learns to protect itself better by prioritizing what truly matters — ensuring cybersecurity resilience and business continuity based on risk.
