CISO metrics that matter: An identity-first approach to security

The gap between measuring security activity and demonstrating outcomes continues to challenge CISOs and IT leadership. While control adoption rates and audit checkboxes satisfy compliance requirements, boards and executives demand evidence of risk reduction. 

Demonstrating business value through cybersecurity metrics can secure executive support and ensure alignment with business objectives. Business leaders require clear, outcome-focused metrics that inform strategic decisions and highlight the direct impact of cybersecurity on organizational priorities. This page outlines a pragmatic set of cybersecurity metrics for CISO reporting centered on identity and access management — specifically password and passkey outcomes — that translate technical progress into business impact.

Effective CISO metrics distill complexity into four elements that resonate with executive leadership. Focusing on key metrics that provide a competitive advantage and support informed decision-making for business leaders is essential.

Risk reduction focuses on exposures trending downward over time. Rather than reporting how many security controls were deployed, show how many credential-based attack vectors were eliminated. Track the percentage decline in weak authentication methods, exposed credentials, and accounts vulnerable to phishing. These risk management metrics demonstrate tangible progress in reducing organizational exposure and addressing cybersecurity risks. Aligning these metrics with cyber risk and the organization's risk appetite ensures that reporting at the board level is meaningful and supports strategic oversight.

Time to mitigate measures organizational responsiveness. Boards want to know how quickly a team moves from detection to containment to full recovery. Long mitigation windows amplify the damage from any incident, so tracking speed demonstrates operational maturity.

Business impact translates security work into tangible outcomes. Quantify incidents avoided through proactive measures, calculate downtime prevented by faster response, and estimate financial exposure eliminated by hardening identity controls. These cybersecurity metrics connect security investments to business continuity and help security leaders justify resource allocation. Key metrics can also demonstrate the value of security investments in protecting digital assets and reducing business risk.

Clarity demands simplicity. A one-page dashboard with stable definitions allows board members to track progress quarter over quarter without relearning a measurement framework. Avoid shifting metrics or complex formulas that obscure trends. Effective CISO dashboard metrics should be intuitive and actionable.

Clear metrics help justify the allocation of resources to security teams. Benchmarking KPI measures is also important to evaluate the organization's cybersecurity posture relative to industry peers.

Modern identity programs require metrics that reflect the shift toward phishing-resistant authentication. The following KPIs provide clear measurement points for identity security and serve as essential cybersecurity performance metrics.

Phishing-resistant MFA coverage measures the percentage of active users protected by passkeys or hardware security keys rather than phishable methods like SMS codes or push notifications. Calculate this as enabled_users ÷ active_users. This metric directly correlates to an organization’s resistance against credential phishing, the leading cause of initial access in data breaches.

Passkey adoption rate tracks the percentage of active users with at least one passkey registered. Monitor weekly deltas to identify adoption velocity and potential friction points. This forward-looking metric indicates progress toward eliminating password-based authentication entirely and reducing cybersecurity risks associated with traditional passwords.

Legacy fallback rate reveals the percentage of authentication events still relying on SMS, time-based one-time passwords (TOTP), or push notifications. High fallback rates signal either technical barriers or user resistance that require remediation. This metric helps prioritize migration efforts.

Compromised credential exposure counts how many organizational passwords appear in breach datasets over time. Integrate breach intelligence feeds into monitoring to detect when employee credentials surface on dark web markets or in publicly disclosed data breaches. Each exposed credential represents an active attack vector. Tracking this metric helps security teams identify security vulnerabilities and reduce the organization's attack surface, ultimately lowering the risk of a data breach.

Password reuse rate measures the percentage of identical passwords across multiple accounts. Calculate this before and after implementing password management controls to demonstrate program effectiveness. Reused passwords magnify the impact of any single breach across an organization’s entire infrastructure. Reducing password reuse lowers breach likelihood and the risk of a data breach across the organization.

Privileged account hardening tracks the percentage of administrative roles restricted to phishing-resistant MFA. Privileged accounts represent high-value targets, so measuring protection coverage for these roles provides a risk-weighted view of an identity security posture.

Deprovisioning time calculates the median time elapsed from employee termination to complete access revocation across all systems. Measure this in hours, not days. Extended deprovisioning windows leave former employees with potential access to sensitive systems and data.

Identity-focused detection and response metrics demonstrate an organization’s ability to identify and neutralize threats quickly. These security operations metrics are crucial for demonstrating operational excellence and help security leaders evaluate the effectiveness of their security controls:

MTTD and MTTR for identity-related incidents should be tracked separately from general security incidents. Credential compromise often precedes larger attacks, so measuring detection and response speed for authentication anomalies provides early warning capability. These incident response metrics are a key indicator of organizational resilience and effectiveness in incident response and security threat management.

High-severity incident count should be reported quarterly with clear trend indicators. Define severity based on business impact rather than technical classification. Include brief context for any increases to distinguish between improved detection and genuine threat escalation.

Patch latency measures the median days required to remediate critical vulnerabilities, particularly those affecting identity infrastructure like authentication servers, directory services, and privileged access management systems. This operational metric reflects an organization’s ability to close known attack vectors before exploitation and serves as a key vulnerability management metric.

Phishing simulation failure rate tracks the percentage of employees who click malicious links or provide credentials in controlled tests. More importantly, measure the trend following targeted coaching. Declining failure rates indicate improving security awareness, while plateau or increases signal the need for more education. Additionally, monitor the impact of false positives on detection accuracy and operational efficiency, as a high volume of false positives can distract from genuine threats and hinder effective incident response.

Log coverage quantifies the percentage of critical applications sending authentication and security events to an organization’s centralized monitoring infrastructure. Gaps in log coverage create blind spots where attackers can operate undetected. Target 100% coverage for all systems handling sensitive data or privileged access.

Focus on leading indicators to proactively address cybersecurity threats and improve the organization's cybersecurity maturity. Leading indicators help organizations identify problems before they manifest as security incidents. These cybersecurity metrics contribute to overall cybersecurity maturity metrics by demonstrating proactive security management:

Enrollment friction identifies drop-off points during passkey setup. High abandonment rates during registration indicate user experience issues that will limit adoption. Map the enrollment funnel to pinpoint where users struggle or give up.

Authentication failure taxonomy categorizes the root causes of failed login attempts: user error, device incompatibility, policy restrictions, or potential attack activity. Understanding failure patterns helps distinguish legitimate usability issues from security events requiring investigation.

Anomalous session patterns detect unusual locations, devices, or access times during both login and post-authentication activity. Baseline normal behavior for each user to identify deviations that may indicate compromised credentials or insider threats.

CISOs are expected to demonstrate measurable progress in compliance, linking security metrics directly to business objectives and risk appetite.

Key compliance metrics provide security professionals and decision makers with actionable insights into the organization’s risk posture. These include the number of audits and assessments performed, the percentage of compliance with industry standards, and the number of regulatory fines or penalties incurred. Tracking these metrics enables security leaders to identify gaps in security controls, prioritize cybersecurity investments, and make informed decisions that align with both regulatory requirements and business goals.

Effective compliance management requires clear communication with board members and other stakeholders. By presenting compliance metrics in a concise, business-focused format, security leaders can provide the actionable insights needed to support strategic decisions and demonstrate the value of cybersecurity programs. This transparency helps align cybersecurity strategy with the organization’s risk appetite and business objectives, positioning security as a business enabler rather than a cost center.
