Key Takeaways
  • RSA Innovation Sandbox winner. Java-focused RASP using JVM bytecode instrumentation with patented data tainting engine for near-zero false positives.
  • Virtual patching applies CVE fixes at the JVM level without code changes or restarts — 150ms time-to-remediate for third-party library vulnerabilities.
  • Claims 2% performance overhead and protection across 80,000+ applications. Targets financial services, healthcare, and government Java environments.
  • Two products: Waratek Secure (automated vulnerability remediation) and Waratek Elevate (legacy app modernization with PCI DSS, GDPR, SOC 2 compliance).

Waratek is a Java-focused RASP solution that embeds security directly into the JVM. Winner of the RSA Innovation Sandbox Award, it protects Java applications from OWASP Top 10 vulnerabilities, zero-day exploits, and known CVEs without code changes or restarts.

The platform ships as two products: Waratek Secure (automated vulnerability remediation) and Waratek Elevate (legacy app modernization with compliance). Both operate at the JVM bytecode level using a patented data tainting engine that tracks untrusted data as it flows through the application.

Waratek claims 2% performance overhead, 150ms time-to-remediate, and protection across 80,000+ applications in production. The company targets financial services, healthcare, and government organizations running business-critical Java workloads.

What is Waratek?

Waratek instruments the JVM at the bytecode level. When untrusted data enters the application from the network, the data tainting engine tracks it through every method call, variable assignment, and framework transformation. If that data reaches a dangerous operation — a SQL query, a deserialization call, a file system access — Waratek knows whether it has been properly sanitized.

This approach differs from pattern-matching RASP tools that look at request signatures. Waratek sees how data actually flows through code, which eliminates the false positives that come from matching attack patterns in legitimate traffic.

Virtual patching applies security fixes at the JVM bytecode level. When a CVE affects a third-party library, Waratek can neutralize the vulnerability without modifying source code, rebuilding the application, or restarting the process. This is particularly valuable for legacy Java applications that cannot be easily patched or redeployed.

Data Tainting Engine
Tracks untrusted data from network entry through every code path. When tainted data reaches a dangerous operation without sanitization, Waratek blocks the request. Eliminates false positives from pattern matching.
Virtual Patching
Applies security fixes at the JVM bytecode level. Remediate CVEs in third-party libraries without code changes, rebuilds, or restarts. Patches take effect immediately when the affected code is loaded.
RSA Innovation Sandbox Winner
Waratek won the RSA Innovation Sandbox competition for its virtualization-based approach to Java runtime security. The platform has since been deployed at what the company describes as the largest production RASP implementation at a Tier 1 global investment bank.

Key Features

Virtual Patching

Apply security fixes without modifying code or restarting applications:

  • CVE Remediation — patch known vulnerabilities in application code and third-party libraries
  • Zero-Day Protection — block exploit patterns before vendor patches exist
  • Framework Coverage — protect Struts, Spring, Tomcat, and other Java frameworks

Attack Prevention

Block attacks at the runtime level:

  • SQL Injection — context-aware detection through data tainting
  • Cross-Site Scripting (XSS) — block malicious script injection
  • Deserialization Attacks — prevent gadget chain exploits
  • Remote Code Execution — block unauthorized command execution
  • Path Traversal — stop directory traversal attempts

API Security

Discover and protect RESTful API endpoints automatically. The agent identifies exposed endpoints and delivers inventory to the Waratek Portal for hardening.

Compliance Automation

Built-in controls for PCI DSS, GDPR, SOC 2, and HIPAA requirements. Security monitoring and logging configured through the Waratek Portal.

Getting Started

1
Set up the Waratek Portal — Choose between the SaaS portal (hosted by Waratek) or Portal Dedicated (on-premises). Configure your organization and application inventory.
2
Deploy the Java Agent — Add the Waratek agent as a JVM argument to your Java application startup. The agent instruments the runtime without code changes.
3
Configure security rules — Define protection rules using Waratek’s ARMR (Application Runtime Model & Rules) engine. Rules specify which vulnerabilities to block and which code paths to protect.
4
Monitor and tune — Review attack detections, virtual patch status, and API inventory in the Waratek Portal. The data tainting engine produces very few false positives, but review findings before switching from monitoring to blocking mode.
Best For
Enterprises with legacy Java applications that cannot be easily patched or modernized. If you need to remediate CVEs in production without touching source code, Waratek’s virtual patching delivers that capability. For multi-language RASP, look at Contrast Protect or Datadog ASM instead.

When to Use Waratek

Waratek fits enterprises running business-critical Java applications that need protection without code changes. The data tainting approach and virtual patching are strongest when you have legacy applications with vulnerable dependencies that cannot be easily updated.

The platform is Java-only. If you need RASP for Node.js, Python, Go, or other languages, look elsewhere. For Java-specific runtime protection with near-zero false positives and minimal performance overhead, Waratek is a strong option.
