From PCI DSS to fraud detection rates: the essential KPIs every bank, insurer, and fintech needs to track.
By Metric Maestro
Financial services organisations face more regulatory scrutiny on cybersecurity than almost any other sector. Yet many security teams still present boards with metrics that don’t connect to the business outcomes regulators and executives actually care about.
Here are the metrics that matter, and how to measure them.
For any organisation handling card payments, PCI DSS compliance is non-negotiable. Measure your compliance percentage per requirement domain, not just the overall audit result. A single failed requirement in PCI DSS 8 (identity management) looks very different from a failed Requirement 11 (testing security systems).
Target: 100% sustained PCI DSS compliance, not just at audit time. Monthly measurement reveals drift between assessments.
The Digital Operational Resilience Act has brought new metrics requirements for EU financial entities. Key metrics to measure:
The percentage of fraudulent transactions detected before settlement. Measure separately by channel (online, mobile, branch, card-present) and by fraud type (account takeover, new account fraud, transaction fraud).
Warning sign: A declining fraud rate is not always good news. If detection rate drops while fraud volume is stable, you may have a detection gap, not improved security.
The ratio of legitimate transactions flagged as fraudulent. High false positive rates cost customer experience and operational efficiency. The tension between detection sensitivity and false positive rate is your primary tuning challenge.
Number of successful account takeover incidents per 100,000 accounts per month. This metric sits at the intersection of fraud and cybersecurity, and is increasingly scrutinised by regulators.
Percentage of incidents where actual recovery time met the defined RTO for that system classification. Critical banking systems typically have RTOs measured in minutes or hours. Measure achievement rate across system tiers.
Financial regulators are increasingly focused on cloud and third-party concentration risk. Measure what percentage of critical functions depend on a single third party or cloud provider. Regulatory guidance increasingly requires this to be below specific thresholds.
Measure the percentage of critical CVEs patched within your defined SLA. Regulators expect documented SLAs and evidence of adherence. For internet-facing systems, the target is typically 24-72 hours for critical vulnerabilities.
Segment remediation velocity by asset class: internet-facing systems, internal systems, endpoints, ATMs/POS. Different risk profiles require different SLAs, and boards want to see them measured separately.
The most effective financial services security views tell a coherent risk story across three dimensions:
Regulatory readiness: are we meeting regulatory requirements? Threat landscape: what are we facing and how are we detecting it? Operational resilience: can we recover when something goes wrong?
Map your security KPIs to these three dimensions before designing your view. A metric without a clear narrative home creates confusion rather than insight.
