Cybersecurity ROI: Top metrics and KPIs

In this Help Net Security interview, Karthik Swarnam, Chief Security and Trust Officer at ArmorCode, discusses key metrics and KPIs to measure cybersecurity ROI. Swarnam shares strategies for enhancing ROI through proactive measures and effective communication with executive leadership.

What are the primary metrics and KPIs used to measure the ROI of cybersecurity investments?

Today, cybersecurity investments are evaluated not just for cost avoidance but for a much broader range of benefits. These metrics include:

Productivity: Cybersecurity measures can significantly enhance productivity by reducing downtime caused by security breaches. This is often reflected in improved operational efficiency and employee performance. One specific metric leveraged to measure this is the Mean Time to Contain (MTTC) after an incident.

Security posture: The overall security posture of an organization can be quantified by tracking the number and severity of vulnerabilities before and after implementing security measures. A key indicator is the reduction in remediation activities while maintaining or improving the security posture. This can be measured in terms of work hours or effort saved. Traditional metrics for this measurement include the number of detected incidents, Mean Time to Detect (MTTD), Mean Time to Respond (MTTR), and patch management (average time to deploy fixes). Awareness training and measuring phishing success rates are also crucial.

Cyber insurance premiums: Effective cybersecurity strategies can lead to reduced premiums for cyber insurance, reflecting a lower risk profile for the organization.

Time to market: Secure development practices, such as shifting security assessments to earlier stages in the software development lifecycle, can reduce the time to market for new products and services. Next-generation security programs should be capable of measuring this attribute.

Cost of risk mitigation: Evaluating the cost-effectiveness of risk mitigation strategies is paramount. This includes comparing the costs of various security measures against the potential losses from security incidents and tying that figure back to patch management, paired up against the number of vulnerabilities remediated. With modern programs, enterprises are empowered to remediate what matters most from a risk perspective. All in all, a remediation cost is a better measure of an organization’s overall security posture than the cost of an incident.

Tool rationalization: By leveraging a governance layer, organizations can eliminate redundant security tools, optimizing their security investments. This continuous evaluation of security tools ensures that only the most relevant solutions are in use. Year-over-year measurements on security spending should be considered in tandem with an organization’s effectiveness barometer, and that barometer should be flexible to fit the particularities of the tool and the circumstance of its application—for each technology being leveraged, there should be three measurable indicators of success.

Customer experience: Improvements in identity and access management can streamline user validation steps, enhancing customer experience by reducing the friction associated with credential validation.

Network performance: Enhancing cybersecurity can also improve network connectivity and reduce latency, contributing to overall system performance and blocking malicious attempts.

Data protection: Implementing robust security controls can minimize the risk and impact of data breaches, protecting an organization from the severe consequences of data loss by monitoring for DLP violations and picking up alerts.

What proactive investment strategies can yield a higher ROI in corporate cybersecurity?

Proactive investment strategies in cybersecurity can significantly enhance ROI by preventing incidents before they occur and optimizing security operations. Key strategies include:

• Leaning into shift-left security: Investing in early security assessments and vulnerability identification can mitigate risks before they become significant issues. This approach ensures that security is integrated into the development process from the beginning.
• Leveraging security posture management: Implementing solutions like Application Security Posture Management (ASPM) helps identify and prioritize risks that matter most to the organization, rather than addressing all vulnerabilities indiscriminately.
• Deploying governance tools: Deploying governance tools enables tailored training for specific employee groups, such as developers, rather than a one-size-fits-all approach. This targeted training enhances the effectiveness of security measures and reduces costs.
• Maximizing tool rationalization: Organizations often accumulate an excess of security tools, leading to overlaps and decreased efficacy. Simplifying, consolidating, and rationalizing security tools can lead to significant cost savings and improved security outcomes. For example, integrating governance, risk, and compliance (GRC) and vulnerability management into a single platform can streamline operations and reduce redundancies.

What are the best practices for demonstrating the ROI of cybersecurity investments to executive leadership and stakeholders?

Demonstrating the ROI of cybersecurity investments to executive leadership and stakeholders requires clear, metrics-based communication. Best practices include:

• Metrics-based approach: Use specific, quantifiable metrics to showcase improvements in security posture and operational efficiency. For example, highlight reductions in vulnerability remediation time, decreases in incident response costs, and improvements in compliance rates.
• Business-aligned security: Show how cybersecurity measures align with and support business objectives. This includes faster product delivery, reduced time to market, and enhanced customer satisfaction.
• Risk-focused reporting: Emphasize how focusing on the most critical risks specific to the business has led to better resource allocation and reduced unnecessary remediation efforts.
• Tool rationalization benefits: Demonstrate cost savings and efficiency gains from rationalizing security tools and eliminating overlap.

How does integrating advanced technologies like AI and machine learning influence cybersecurity ROI?

Integrating advanced technologies such as AI and machine learning can profoundly influence cybersecurity ROI by dynamically optimizing security solutions, allowing organizations to adapt to evolving threats in real time. These technologies enable enhanced threat detection, identifying and responding to threats more quickly and accurately than traditional methods, thus reducing the likelihood and impact of security incidents.

Additionally, AI-driven automation streamlines security operations, reducing the need for manual intervention and freeing up resources for more strategic activities. This combination of dynamic threat management, efficient response capabilities, and operational automation significantly boosts the overall effectiveness and cost-efficiency of cybersecurity investments.

What advice would you give security professionals looking to improve their organization’s cybersecurity ROI?

To improve cybersecurity ROI, security professionals should:

• Establish clear metrics: Define and measure key metrics across various domains such as identity & access management, risk remediation, software development, data loss prevention, and messaging security.
• Develop relevant measures: Ensure that the metrics used are relevant and meaningful to the organization’s specific context and goals.
• Set security tolerance levels: Establish acceptable levels of risk and use these as benchmarks for evaluating security performance.
• Regular reporting: Produce regular security measurements and reports to maintain visibility and accountability. This helps in continuously tracking progress and making informed adjustments to security strategies.

By prioritizing the above, organizations can demonstrate the value of their cybersecurity investments and achieve a higher return on these investments through improved security and operational efficiency.
