In the evolving world of cybersecurity, the most dangerous threats are often silent and invisible—until it's too late. While organizations focus on patching known vulnerabilities and fortifying perimeter defenses, attackers frequently operate from a different angle: exploiting zero-day vulnerabilities before anyone even knows they exist.

But what happens when you're already exposed—and you don't even know it?

What Are Zero-Day Vulnerabilities?

A zero-day vulnerability refers to a software or application flaw that is unknown to the vendor and has no official patch available. These flaws can be exploited immediately after discovery—often before the development or security teams are even aware of their existence. The result? Stealthy, high-impact attacks that bypass traditional security controls.

May 2025: AppTrana’s Real-Time Mitigation in Action

In May 2025 alone, Indusface’s AppTrana WAAP (Web Application & API Protection) platform detected and blocked 463 real-world zero-day attacks across live web applications—in real time.

These weren't theoretical proof-of-concepts. They were active, ongoing attempts to compromise systems and extract sensitive data. AppTrana identified, analyzed, and neutralized every single one of them—before they could do any harm.

A Closer Look at the Threat Landscape:

???? 198 SQL Injection (SQLi) attempts targeting backend databases

???? 174 Cross-Site Scripting (XSS) attacks aimed at session hijacking

???? 30 Path Traversal attacks attempting to access restricted files

???? 28 Command Injection attempts to execute unauthorized commands

???? 7 Server-Side Request Forgery (SSRF) attacks probing internal services

What Made the Difference? AppTrana’s Proactive Core Rule Engine

AppTrana’s ability to stop these threats lies in its proactive Core Rule Engine, which continuously evolves using threat intelligence and behavioral analysis. Unlike traditional Web Application Firewalls (WAFs) that rely on static signatures, AppTrana dynamically detects and blocks unknown, zero-day exploits in real time—before they become a breach headline.

This isn’t just threat detection—it’s resilient defense built for a world of constant unknowns.

The True Measure of Security: Resilience to the Unknown

Modern attacks don’t always fit predictable patterns. That’s why relying on reactive, signature-based tools is no longer enough. AppTrana delivers adaptive security, defending applications and APIs with the flexibility and intelligence needed to counter today’s most elusive threats.

463 zero-day attacks. 100% blocked. Zero data loss.

That’s not just a statistic—it’s operational resilience in action.
