Three application security KPIs cut through alert noise to reveal actual risk: viable attack count, vulnerability escape rate and application coverage completeness. Unlike traditional metrics that measure alert volume, these KPIs leverage graph intelligence to correlate attacks with confirmed vulnerabilities at runtime, achieving verified accuracy while reducing investigation time by orders of magnitude.
According to Contrast Security's Software Under Siege 2025 report, applications face an average of 81 viable attacks per application monthly that bypass traditional defenses entirely. Your security dashboard shows thousands of alerts, but which ones represent real risk? The problem is not the tools. The problem is the KPIs.
Traditional dashboards display thousands of blocked attacks and endless threat detections. Security teams monitor these metrics, believing comprehensive visibility protects their applications, but the metrics lie. Alert fatigue stems from measuring activity instead of accuracy. Dashboards count every potential threat, regardless of whether vulnerable code exists to exploit.

Security tool |
What it does well |
Critical blindspot |
|---|---|---|
|
WAF |
Filters perimeter traffic, blocks known signatures |
Minimal correlation to actual exploits (most alerts are noise) |
|
EDR |
Detects OS-level threats (malware, privilege escalation) |
Cannot see application-layer attacks like deserialization |

SIEM |
Correlates security events across the organization |
Without application context, shows volume not accuracy |
Each tool excels at its designed function but creates blind spots at the application layer. Application Detection and Response (ADR) shifts the paradigm by correlating attacks with vulnerabilities at runtime using graph intelligence.
Traditional dashboards might display tens of thousands of blocked requests each month, while revealing only a few dozen viable attacks. According to Contrast research, applications face an average of 81 viable attacks per application monthly. This thousand-fold difference transforms security operations from drowning in alerts to focused threat response.
What it measures: Confirmed attacks against reachable and exploitable vulnerabilities.
The distinction matters because traditional tools measure perimeter activity. Thousands of blocked requests might represent automated scanners probing for vulnerabilities that don't exist. These thousands of blocked requests obscure the alerts that actually matter to security teams, creating alert fatigue and increasing mean time to respond for genuine threats.
Vulnerability escape rate reveals whether your secure development practices actually work.
What it measures: The rate at which new vulnerabilities are introduced despite AppSec controls.
Rising VER indicates that development teams create security flaws faster than AppSec can prevent them. Falling VER shows successful secure coding practices. Track VER monthly or per release cycle, then correlate it with the viable attack count to understand whether pre-production improvements translate into runtime risk reduction.
Application coverage completeness determines whether your security metrics tell the whole truth or only part of the story.
What it measures: Percentage of applications with runtime visibility.
If 40% of applications lack runtime instrumentation, your viable attack count shows only 60% of actual exposure. Blind spots create false confidence. Display coverage percentage prominently and identify high-risk applications without coverage.
Traditional analytics correlate events without understanding relationships. Graph intelligence observes five critical dimensions simultaneously: code execution paths, data flows, API interactions, vulnerability locations and attack patterns.
Detection in action:
The difference: attack detected AND vulnerability confirmed. This transforms the dashboard experience from reviewing thousands of alerts to investigating dozens of correlated threats.
EDR metrics measure OS-level threats but miss application-layer attacks. WAF metrics track perimeter defense but show limited correlation with exploits. SIEM metrics correlate events but lack application context.
Application Detection and Response (ADR) metrics measure viable attacks plus confirmed vulnerabilities with verified correlation, filling the blind spot in every other security tool. This isn't a replacement. It's complementary visibility that adds application context that traditional tools cannot measure.
Use your SIEM as the hub for all security visibility. ADR sends viable attack events to your existing Splunk or Microsoft Sentinel instance, along with vulnerability correlations and coverage metrics. Nothing stops operating. Your SIEM continues correlating events, your WAF keeps blocking perimeter attacks and your EDR detects endpoint threats.
Alert fatigue reduction: Security teams focus on dozens of viable attacks (an average of 81 per application per month, according to Contrast research) rather than investigating thousands of probe alerts. Investigation time drops by orders of magnitude while threat coverage remains complete.
Better prioritization: Graph intelligence reveals that three deserialization vulnerabilities are exploited daily, while others remain untargeted, enabling focused remediation where attackers actually strike.
Executive communication transforms: Your dashboard shifts from "we blocked 10 million attacks" to "we reduced viable attack exposure by 40% while maintaining zero successful exploits."
The three most critical Application Security KPIs are viable attack count, Vulnerability Escape Rate (VER), and application coverage completeness. Unlike traditional metrics that focus on the sheer volume of blocked requests, these KPIs prioritize accuracy by correlating attacks with confirmed vulnerabilities. This allows Security Operations Center (SOC) teams to ignore harmless probes and focus on threats with a high likelihood of successful exploitation.
Viable attack count reduces alert fatigue by filtering out "noise"—such as automated scanners hitting non-existent vulnerabilities—and highlighting only the attacks targeting reachable code. While a traditional WAF might report thousands of blocked requests, the viable attack count often reveals only a few dozen genuine threats. This thousandfold reduction in data allows security analysts to spend their time on high-impact remediation rather than on manual triage.
Vulnerability Escape Rate (VER) is a metric that measures the frequency at which security vulnerabilities are introduced into production environments despite existing pre-production security controls. A high or rising VER suggests that development teams may need additional security training or that the current AppSec testing tools are insufficient. Conversely, a falling VER indicates that secure coding practices and "shift left" initiatives are effectively reducing risk before deployment.
Application coverage completeness measures the percentage of an organization's application portfolio that has active runtime visibility. Without 100% coverage, security metrics like viable attack count only provide a partial view of the actual risk landscape. High coverage ensures there are no blind spots where attackers could operate undetected, providing leadership with a more accurate and trustworthy assessment of the organization’s overall security posture.
Application Detection and Response (ADR) metrics differ from WAF or EDR alerts in that they provide deep application-layer context. While WAFs monitor perimeter traffic and EDRs monitor operating system activity, ADR uses graph intelligence to observe code execution and data flows at runtime. This allows ADR to confirm whether an attack is exploiting a known vulnerability in the application, providing a level of verified correlation that traditional tools cannot match.
Security dashboards should reveal risk, not create noise. Three KPIs transform security visibility from measuring alert volume to tracking attack accuracy. Graph Intelligence makes this possible by mapping code, vulnerabilities, and attacks at runtime, providing the application context that traditional security tools lack.
Start with viable attack count. This single metric immediately reveals the difference between perimeter activity and application risk, cutting through thousands of alerts to show the dozens of attacks that actually matter.
