Reporting security performance to the C-suite is perhaps the most daunting challenge a CISO faces.
Technical jargon is lost on them, and they have grown weary of hearing the same old “risk stories.” As a result, when you request a budget, they view it as alarmism; when no incidents occur, they perceive you as having nothing to do.
The root of the problem is that we consistently communicate using our own technical vocabulary. We keep trying to pull leadership into our domain of expertise, which is a lost cause. The correct approach is to completely reconstruct our reporting using their language.
The Board of Directors only cares about three things: Budget, Risk, and Time.
Every aspect of our security work must be translated into these three language. Here is the specific methodology for constructing a “one-page report” driven by Valuable Security Metrics.
Part I: Budget (Money) — What is the return on our investment?
When management approves your budget, it is essentially an investment. What they care most about is ROI. Calculating ROI in cybersecurity is challenging, so we can use a concept they easily understand instead: cost avoidance.
Your core metric to focus on: Quantifiable potential failure cost avoidance.
Calculation formula: Potential Failure Cost = (Estimated Business Loss) × (Defense Instability) × (Detection Risk Factor)
Data Source:
- Estimated Business Loss This is a concrete dollar amount (e.g., S$1 Million). You must calculate this in collaboration with business and finance units; it serves as the “anchor” for your entire formula.
- Defense Instability This is not a theoretical “guess.” It must be an objective success rate derived from your real-world environment. Using the Atlas Cybersecurity Validation Platform, you can validate your posture by repeatedly running attack playbooks against specific targets. For example, if a specific attack is executed 10 times and your defenses fail 3 times, your Defense Instability is 30% (0.3).
- Detection Risk Factor This factor quantifies the risk of our existing defenses going “blind.” The calculation is: (1 – Control Effectiveness). Control Effectiveness is also derived from real-time validation data within the Atlas Cybersecurity Validation Platform.
- Example: Out of the 10 attack techniques mentioned above, if your EDR/SIEM tools successfully alert or block 8 times, the control Effectiveness is 80% (0.8). It means Detection Risk Factor is (1 – 0.8) = 0.2. This indicates a 20% probability that your current defense system will fail to detect the attack. Higher effectiveness leads to a lower Detection Risk Factor.
Reporting Example:
This quarter, through continuous validation, we identified and blocked an attack pathway that could have paralyzed the core transaction system. The success rate (P) of simulated attacks via this pathway stood at 30%, while the false negative rate (D) of our existing monitoring system against such attacks was as high as 90%. According to financial estimates, the daily loss (L) incurred by the system downtime would be approximately SGD 960,000 .Thus, our work this quarter helped the company avoid potential failure costs of around SGD 259,200 , calculated as SGD 960,000 (L) × 30% (P) × 90% (D). In contrast, the cost incurred for us to complete this work was only SGD 9,600 .
Part II: Risk — Are our core operations truly secure?
The Board isn’t interested in the technicalities of the MITRE ATT&CK matrix. What they care about is the company’s lifeblood: Core Business Operations. Your challenge is to translate technical vulnerabilities into tangible business risks.
The Valuable Security Metric you need here is: The Critical Business Resilience Score.
This is not meant to be an absolute, surgical figure. Instead, it serves as a trend-based indicator for internal benchmarking. You can define this score alongside your team by looking at several key pillars:
- Validated Attack Paths: The number of validated routes an attacker could take to reach this specific business unit (Lower is better).
- Effectiveness of Key Controls: The real-world performance of your existing defenses against these paths (Higher is better).
- Mean Time to Repair (MTTR): Our historical average speed in neutralizing threats (Shorter is better).
The Data Source: These insights are driven by the Atlas Cybersecurity Validation Platform. It provides the objective data required to map out attack paths and measure control effectiveness across your various business systems.
- Reporting Example:
“This quarter’s Security Resilience Score highlights a clear divide between our core operations.
Our Online Transaction System saw its score surge from 70 to 85 after we successfully identified and severed two critical attack paths. Conversely, our Supply Chain Management System dipped from 65 to 60.
Through proactive security validation using the Atlas Cybersecurity Validation Platform, we discovered that newly deployed API modules have introduced unvalidated vulnerabilities. Data shows that current defenses are underperforming against simulated attacks. Remediating these API risks will be our primary objective for the next quarter to ensure business continuity.”
Part III: Time — The Race Against the Clock. How quickly can we restore normalcy?
The Board understands that absolute security is a myth. Their third concern is Cyber Resilience: if a breach occurs, how quickly can we bounce back? This is the heartbeat of Business Continuity.
The Valuable Security Metric you need is: Mean Time to Repair.
Forget about sifting through messy historical logs from past incidents. Instead, you should measure this through planned, proactive security validation. By launching a simulated attack, you can “start the stopwatch” and measure the real-time performance of your entire response lifecycle: Detection, Containment, Eradication, and Recovery.
The Data Source: Using the Atlas Cybersecurity Validation Platform, you can periodically execute end-to-end attack playbooks. This allows you to record the actual time your teams and security tools take to complete each step of the response loop, providing a validated benchmark of your operational readiness.
- Reporting Example:
Last month, we organized an automated data breach attack and defense drill. Data shows that our full-cycle response time from detection to complete containment was 4 hours, representing a 60% reduction from the 10 hours recorded in the drill conducted six months ago. This proves that our investments in SOAR and emergency response plans over the past six months have delivered tangible results.
One-Page Report
Therefore, the final one-page report submitted to the management will only contain these three core sections:
- How much potential loss have we avoided? (Budge)
- Is our core business secure? (Risk)
- Can we withstand incidents? (Time)
These three sets of data cannot be guessed, nor can they be sustained through manual testing. You must have a set of tools that can continuously and objectively measure your security system. This is the value that the Atlas Cybersecurity Validation Platform can provide to you.
