Blog  Penetration Testing ROI: The Value of Vigilance

The compelling case for penetration testing has long been established. But putting a specific number on its ROI remains difficult. Similar to those of other preventive measures such as acquiring health insurance or upgrading your door lock, the real value of penetration testing emerges only when an unwanted incident occurs. For organizations, these incidents include devastating data breaches that mostly rely on overlooked vulnerabilities that would likely have been detected and remediated had penetration testing been performed.

The average cost of a data breach was US$4.45 million in 2023, based on an IBM study. This cost continues to rise year after year as cyber criminals refine their tools and tactics. While penetration testing is only one component in the larger security infrastructure, it plays a crucial role. Regular pen testing enables organizations to gain valuable insight into their security posture, drive compliance with industry standards and regulations, and enhance resilience against cyber threats. 

This article explores the long-term value and cost-effectiveness of investing in regular penetration testing as part of an organization’s security strategy.  

What is Penetration Testing? 

Penetration testing is a cybersecurity service that uses the techniques of threat actors to launch simulated attacks on an information system. The goal is to proactively identify and remediate vulnerabilities before they can be exploited. Penetration testing provides an objective assessment of a company’s security posture, helps improve cyber resilience, and facilitates regulatory compliance. By adopting the tools and mimicking the behavior of criminal hackers in a controlled environment, pentesters (or ethical hackers) provide valuable insight into how organizations should protect their network, assets, and customers.  

The ROI of Penetration Testing 

Penetration testing is an indispensable process for organizations that want to assess their security level, comply with regulations, manage risks, and build trust with customers. By conducting regular penetration testing, organizations can achieve several benefits: 

• Cost Savings: Pen testing can help organizations avoid costs associated with data breaches and cyber-attacks. These include financial losses, business disruption, reputational damage, and legal liabilities. 
• Improved Security Posture: Pen testing helps organizations stay ahead of evolving threats and improve their overall security posture. By identifying and fixing vulnerabilities, organizations can enhance their security controls and policies, and prevent unauthorized access to their systems and data. Penetration testing also helps organizations test their incident response capabilities and improve their resilience to cyberattacks. 
• Regulatory Compliance: Pen testing helps organizations meet compliance requirements and industry standards. Many compliance frameworks (such as PCI DSS, ISO 27001, and NIST CSF) require or recommend regular penetration testing as part of the security assessment process.  

Calculating the ROI of Penetration Testing 

To justify the cost of pen testing, organizations need to consider its return on investment (ROI). The ROI of penetration testing depends on several factors, including: 

1. Cost of testing: This includes the pentester fees, the tools, and resources they use, and the time and effort they spend on the testing process. 
2. Cost of remediation: This includes the expense of fixing the vulnerabilities and gaps identified by the pentesters, as well as the potential downtime and disruption caused by the remediation process. 
3. Potential cost savings: This includes the avoided losses from halted data breaches and cyberattacks. Note that in Q2 2023, organizations faced an average of 1258 cyberattacks per week, according to Check Point. 
4. Value of customer trust: This considers the cost of customer attraction, retention, and attrition as driven by a serious security incident or demonstrated by the company’s commitment to protecting all its stakeholders.  

To calculate the ROI of penetration testing, organizations can use different methods and formulas, depending on their specific goals and context. You can compare the cost of testing and remediation with the estimated cost of a data breach for similarly sized companies in the same industry. You can also compare the cost of testing and remediation with the expected revenue increase from improving customer satisfaction and loyalty, based on the average customer lifetime value and retention rate. These methods can help quantify the benefits of pen testing and demonstrate its value to stakeholders. 

How to Maximize the ROI of Penetration Testing 

Penetration testing is a valuable investment for organizations that want to improve their security and reduce their risk of cyberattacks. Here are some best practices to get the most out of penetration testing: 

1. Test regularly. Penetration testing is not a one-time event. It should be performed at least once a year to stay on top of evolving threats. 
2. Prioritize remediation. Promptly address weaknesses that have been uncovered by a pentest. Otherwise, malicious hackers might exploit vulnerabilities before you can fix them.  
3. Choose the right pentester: Not all penetration testing providers are equal. Go for experienced, duly certified, and trusted practitioners.  

Real-World Cases That Prove the Value of Pen Testing 

Here are some examples of how penetration testing has benefited real-world companies: 

• A financial institution conducted a penetration test to evaluate the security of its online banking platform. The test revealed several vulnerabilities and configuration weaknesses. The institution was able to fix these issues before they could be exploited by threat actors, saving them from potential data breaches, fines, and reputational damage. 
• A healthcare provider performed a penetration test to check the security of its information systems. The test uncovered several significant weaknesses in the physical, digital, and administrative measures used to secure the facilities, networks, and critical systems. These findings enabled the healthcare provider to address vulnerabilities and mitigate the risk of cyberattacks.  

• A software company hired a penetration testing provider to help secure its feature-rich services and align pen testing with Agile development processes. The provider implemented continuous pentesting and comprehensive tracking to reduce the software company’s business risk and to align security with fast-paced development and release of product features. 

Conclusion 

For organizations that value their security and those of their customers, regular penetration testing can never be an option. It has long become an essential investment that accrues significant value over time. While it is challenging to put a specific number on pen testing ROI, it is easy to see the alternative scenarios when companies drag their feet on proactively assessing their defense posture and fixing exposed vulnerabilities. 

As cybercrime worsens, the average cost of a data breach can potentially force small- to medium-sized businesses to permanently close shop. Meanwhile, the tightening regulatory environment and the global trend to strengthen privacy legislation means stiffer fines and penalties for organizations that adopt lukewarm security programs.  

As case study after case study proves, regular penetration testing not only helps strengthen cyber resilience but also helps build customer trust in your services.
