Runtime Protection Agent

Secure your environment autonomously

Defend your APIs, agents, and web apps from exploits, bots, DDoS, and other attacks. Runtime Protection Agent gives you one control pane for posture management, testing, and protection.

API Posture

See and score every API you run

Detect and evaluate every API in your environment to gain complete visibility and improve your security posture.

Autonomous inventory

Discovers every API — internal, external, and third-party — automatically.

Risk evaluation & scoring

Scores each API for exposure, sensitive data, and drift so you know what to fix first.

Fix in the developer workflow

Routes findings into the tools developers already use, so issues get fixed at the source.

API Advanced Protection

Stop attacks hiding in your traffic

Analyze behavior to detect intent across all of your traffic, allow good interactions, and block attacks.

Context-aware detections

Flags credential stuffing, abuse, and business-logic attacks in real time.

Trace complete user sessions

Reconstructs user sessions end to end, so every request has context.

Deep forensic analysis

Retains full-fidelity traffic data for forensics and proof of enforcement.

AI Posture

Find and secure every AI asset

Continuously find and fix new agents, LLMs, MCPs, and AI components.

Automatically discover AI assets

Finds every agent, LLM, and MCP you call — even the ones no one registered.

Score risk & enforce policies

Rates each AI component for risk and applies your governance policies automatically.

Test & simulate attacks

Runs prompt-injection and data-leakage tests before attackers do.

AI Firewall

Block AI attacks in real time

Defend against AI-specific attacks and unwanted interactions.

Block bad requests & responses

Blocks prompt injection and unsafe model output inline, before they land.

Detect attack chaining

Spots multi-step techniques that stitch benign-looking requests into a real attack.

Prevent lateral movement

Stops a compromised agent or tool call from reaching systems it shouldn't touch.

Protection that builds trust

Have confidence in your security. Every action the Runtime Protection Agent takes is observable, explainable, and governed by your policies.

Auditable proof

A full-fidelity data lake retains security data for 90 days, with journey and incident tracing for forensics and clear proof that policies were enforced.

Natural-language investigations

Query the agent about incidents and policies to get fast, understandable analysis of events.

Simple policy updates

Add new policies, test them on live traffic, then deploy — without disrupting existing protections.
