18 Data Security Metrics & KPIs You Need To Track

Ever feel like you’re throwing darts in the dark when it comes to measuring your security program’s effectiveness?

You’re not alone. According to PWC, 37% of CEOs feel extremely exposed to cyber risks.

That’s a pretty high number when you consider that only 15% of organizations say their InfoSec reporting metrics meets their expectations (EY).

The problem? Many organizations either aren’t tracking the right metrics or aren’t using them effectively.

Without the right data, you can’t make informed decisions or show stakeholders that your security investments are paying off.

So, what metrics should you focus on?

Let’s break down what security metrics and key performance indicators (KPIs) are, why they’re important, and which ones are worth your attention.

What are data security metrics?

Security metrics are like your system’s pulse check. They’re quantifiable measurements that give you a snapshot of your security posture at any given time. Think of things like:

• Number of data breaches
• Percentage of systems patched
• Time to detect and respond to threats

These metrics are specific and technical, giving you the nitty-gritty details on how well your individual security controls are performing. If a single system is out of compliance or a specific vulnerability keeps popping up, these are the metrics that tell you something’s off.

What are KPIs in cybersecurity?

Now, let’s level up a bit. Security KPIs (Key Performance Indicators) are your high-level indicators that align more closely with business goals. While metrics focus on specific security controls, KPIs are designed to measure how well your overall security strategy is working. They answer bigger-picture questions like:

• How effective is our security investment?
• Are we reducing risk in a meaningful way?
• What’s the business impact of our cybersecurity program?

For example, while “Number of data breaches” is a metric, a KPI would be “Percentage reduction in data breaches year-over-year.” See the difference? One’s tactical, the other’s strategic.

Why do data security metrics and KPIs matter?

Good metrics and KPIs aren’t just for show; they provide insight and context that drive decisions. They help answer critical questions, like:

• Are your security controls effective?
• Where should you allocate resources?
• What’s the ROI of your security program?

Without these answers, you’re flying blind. Worse yet, when it comes time to justify budgets or respond to a security incident, you won’t have the data to back up your decisions.

How to align IT security metrics and KPIs with business goals

Here’s the thing: your security program doesn’t exist in a vacuum. If your metrics aren’t aligned with business goals, you’ll end up measuring things that don’t matter. Here’s a quick guide to aligning your security metrics with business objectives:

1. Understand the Business Objectives

Sit down with your stakeholders and get clear on what’s most important to the business. Whether it’s revenue growth, regulatory compliance, or operational efficiency, this is your starting point.

2. Map Security Goals to Business Objectives

If protecting customer data is a priority, frame your metrics around customer trust, data protection, and regulatory compliance.

3. Choose the Right Metrics

Pick metrics that are not just security-focused, but that also demonstrate business value. Think: reduced incident costs, improved customer trust scores, or faster recovery times.

4. Automate and Report Regularly

Use tools to automate data collection where possible, and create dashboards that show security’s impact in a language the business understands.

5. Evolve with the Business

As business goals shift, be ready to adjust your metrics and KPIs accordingly.

How to choose the right cybersecurity metrics

Here’s the bottom line: when choosing security metrics, always ask yourself: Does this metric help tell a story about risk and value that my business stakeholders care about?

If the answer’s no, either change it or rethink how you’re presenting it. Metrics that matter are the ones that speak to both security and business impact.

And one last thing—remember to keep the conversation about cost.

At the end of the day, showing how security prevents expensive security incidents and keeps operations running smoothly is what’s going to get buy-in from the C-suite.
