12 Most Important ISO 27002 (IEC 27002) KPIs


The top Implementing ISO 27002 effectively involves using KPIs to evaluate the adequacy and effectiveness of information security controls. These metrics support continual improvement in information security management.

KPIs for ISO 27002 focus on aspects such as vulnerability management effectiveness, the impact of security training programs, and the efficiency of incident response mechanisms.

This article showcases the Most Critical 12 KPIs for ISO 27002 (IEC 27002) and Associated Benchmarks.

1. Number of Security Incidents

Number of Security Incidents is a critical KPI that reflects an organization's vulnerability to cyber threats.

High incident counts can lead to financial losses, reputational damage, and regulatory scrutiny. Effective tracking enables proactive measures to enhance operational efficiency and strengthen security protocols.

Organizations that manage this metric effectively often see improved financial health and reduced risk exposure. Learn more about the Number of Security Incidents KPI.

These 12 KPIs were selected from the ISO 27002 (IEC 27002) KPI database to provide a balanced view of security performance. They cover both leading indicators, such as Unauthorized Access Attempts and Patch Management Effectiveness, and lagging indicators like Number of Security Incidents and Data Breach Impact. This set spans detection, response, remediation, and compliance dimensions, ensuring comprehensive monitoring of security control health and incident management.

Track Mean Time to Detect (MTTD) alongside Mean Time to Respond (MTTR) to evaluate detection efficiency versus response agility—an increasing MTTD with flat MTTR signals detection gaps requiring investment in monitoring. Compare Vulnerability Remediation Time with Patch Management Effectiveness; divergence indicates patching delays or incomplete coverage. Monitor Security Audit Findings Closure Rate in relation to Compliance with Security Policies—low closure rates with high compliance suggest audit process bottlenecks rather than policy adherence issues.

Prioritize implementing Number of Security Incidents and MTTD first, as these are typically available from existing security logs and provide immediate insight into incident frequency and detection speed. Follow with Vulnerability Remediation Time to address root causes of incidents. The full ISO 27002 (IEC 27002) KPI set, including advanced metrics beyond these 12, is accessible in the KPI Depot database for deeper security performance management.

FAQs about KPI Depot


What does unlimited web access mean?

Our complete KPI and benchmark database is viewable online. Unlimited web access means you can browse as much of our online KPI and benchmark database as you'd like, with no limitations or restrictions (e.g. certain number of views per month). You are only restricted on the quantity of CSV downloads (see questions below).

What's the difference between the Basic and Pro plans?

Both plans include unlimited web access to the full KPI database and benchmark database, interactive Strategy Maps for every KPI group, and 2,000+ OKR examples.

The Basic plan includes 5 CSV downloads per month and is designed for individual research use.

The Pro plan includes 20 CSV downloads per month and unlocks the full deliverable workflow: save your customized Strategy Maps and export them as Balanced Scorecard CSV templates, complete with KPI names, formulas, monthly tracking columns, and links to benchmark data. Open the export in Excel and start tracking immediately.

Can I try the interactive Strategy Map before subscribing?

Yes. Every KPI group includes an interactive Strategy Map that anyone can open, no subscription required. You can add, remove, and rearrange KPIs across the 4 Balanced Scorecard perspectives (Financial, Customer, Internal Process, and Learning & Growth) to build a map tailored to your organization.

Saving your customized map and exporting it as a Balanced Scorecard CSV template are Pro plan features. To help you turn that CSV into a polished, ready-to-track scorecard, we also offer 5 free Balanced Scorecard Excel templates that pair with your export.

Can I download KPI group data as a CSV?

Yes. You can download a complete KPI group (which includes all inclusive KPIs and respective attribute data) as a CSV file. To gain a better sense of the KPI data included, you can download a sample CSV file here.

Can I download benchmark data as a CSV?

Yes. On individual KPI pages, you can download all available benchmarks for that KPI as a CSV file. To gain a better sense of the benchmark data included, you can download a sample CSV file here.

Each CSV download, whether for a KPI group or for benchmarks, consumes 1 of your monthly CSV download credits.

What if I need more CSV downloads in a month?

You can purchase additional download credits at any time: $8 each on the Basic plan, $5 each on the Pro plan. Credits never interrupt your workflow, so you'll never be locked out of a download you need mid-project.

How does KPI Depot pricing compare to other benchmark data sources?

Benchmark data is traditionally expensive. Subscription research and advisory services typically run $2,400 to $70,000+ per year, and a single benchmarking assessment can cost $5,000 at nonmember rates. Compiling benchmarks yourself from public sources takes weeks of analyst time per project.

KPI Depot includes unlimited web access to all 35,625 source-attributed benchmarks on every plan, starting at $499 per year. Each benchmark documents its source, company size, time period, industry, geography, and sample size, so your targets hold up under scrutiny.
