Imperva RASP 2026: WAF-Integrated App Defense

Name: Imperva RASP
Availability: OnlineOnly

Imperva RASP embeds security directly into Java and .NET applications, protecting them from the inside. The main draw is the two-way integration with Imperva’s WAF — attack patterns detected by RASP feed into WAF rules, and vice versa.

The product evolved from Imperva’s acquisition of Prevoty in 2018. It requires no code changes and no tuning. Deploy the agent, and it starts blocking attacks based on behavioral analysis rather than pattern matching.

What is Imperva RASP?

Imperva RASP sits inside the application runtime, monitoring how requests flow through code. When it spots an attack pattern — SQL injection, XSS, remote code execution, or business logic abuse — it blocks the request before it reaches vulnerable code.

What makes it different from standalone RASP products is the WAF integration. RASP sees attacks that bypass the WAF (encryption, encoding tricks, zero-days). The WAF sees network-level threats RASP cannot. Together, they share threat intelligence and coordinate blocking across both layers.

WAF + RASP Coordination

Attack patterns detected by RASP automatically inform WAF rules. The WAF feeds network-level threat intelligence back to RASP. Both share a single dashboard for security visibility across network and application layers.

Zero-Tuning Protection

ML-based behavioral analytics detect attacks without rule tuning. The agent learns normal application behavior and flags deviations. No signature updates or manual policy adjustments needed after deployment.

Prevoty Heritage

Imperva acquired Prevoty in 2018 to build its RASP capabilities. Prevoty pioneered the “language-theoretic security” approach — analyzing how inputs flow through an application’s data model rather than matching against known attack patterns.

Key Features

Runtime Protection

The RASP agent protects against:

SQL injection — context-aware detection inside the database query builder
Cross-site scripting (XSS) — blocks malicious scripts at the rendering layer
Remote code execution — prevents unauthorized command execution
Authentication bypasses — detects forged or manipulated auth tokens
Business logic attacks — identifies abuse of application workflows

Attack Analytics

Imperva provides attack visibility through:

Attack visualization and timelines
Attacker profiling across sessions
Threat intelligence correlation
Incident response workflows

File Integrity Monitoring

Monitors file system changes within the application environment. Detects unauthorized modifications to configuration files, application binaries, and system files.

Getting Started

Choose deployment model — Cloud (managed by Imperva), on-premises (self-hosted), or hybrid. Organizations already using Imperva WAF typically add RASP through the same management console.

Deploy the agent — Install the RASP agent on your Java or .NET application servers. The agent instruments the runtime without code changes or application restarts.

Configure WAF integration — Connect RASP to your Imperva WAF for two-way threat intelligence sharing. Attack patterns flow between both products automatically.

Monitor and review — Check the unified Imperva dashboard for blocked attacks, vulnerability detections, and threat intelligence correlations across your WAF and RASP deployments.

Best For

Organizations already invested in the Imperva security ecosystem. If you run Imperva WAF, adding RASP gives you coordinated protection across the network and application layers through a single dashboard. For standalone RASP without a WAF dependency, look at Contrast Protect or Dynatrace.

When to Use Imperva RASP

Imperva RASP fits organizations that already use Imperva WAF or other Imperva products and want coordinated runtime protection. The zero-tuning approach and WAF integration make it straightforward to deploy.

It is less suited for teams that want standalone RASP without an Imperva WAF dependency, organizations running languages beyond Java and .NET, or those looking for open-source alternatives.

Frequently Asked Questions

What is Imperva RASP?

Imperva RASP is a runtime application self-protection solution that embeds security directly into applications and integrates with Imperva’s broader security platform including their WAF.

Is Imperva RASP free or commercial?

Imperva RASP is a commercial product available through cloud, on-premises, or hybrid deployment models.

How does Imperva RASP protect applications at runtime?

It uses an agent-based approach to monitor application execution, detect attack patterns like SQL injection and XSS, and block malicious requests without requiring code changes.

Does Imperva RASP block attacks automatically?

Yes. Imperva RASP detects and blocks common attacks including SQL injection, XSS, remote code execution, and business logic attacks in real-time.

How does Imperva RASP integrate with Imperva WAF?

RASP shares threat intelligence with Imperva WAF, enabling coordinated blocking across both network and application layers with a unified security dashboard.
