WAF for the Agentic Era

Virtual Patch web apps in minutes

Legacy WAFs weren’t designed to keep up with Agentic attacks.  Impart allows security teams to respond quickly to zero days and agentic attacks with WAF that can be designed, tested, and deployed in minutes with AI security agents.

What it Does

WAF at runtime. Built for execution. Not inspection.

AI agents and agentic workflows have fundamentally changed how attacks execute. Impart runtime enforcement controls what requests do, at the speed of AI.

Inspect

every request with full context—headers, payloads, session state, and prior behavior

Decide

what the request is allowed to do, based on intent, not pattern matching

Enforce

before execution completes, blocking injection, exfiltration, and abuse before your app processes the input

The AI attack surface is different. Your WAF has to be too.

AI-driven enforcement with Impart runs across payloads, identity, and session rather than signature matching on individual requests. This is how we’re different.

OWASP Top 10 enforced at runtime — injection, XSS, CSRF, and beyond

Prompt injection and novel AI attack variants detected without prior signatures

Behavioral intent modeled across every request, not matched against static rules

Proposes and manages rules from observed behavior — no manual tuning

Requests evaluated in session context, not isolation

Multi-step attacks visible before individual requests cross thresholds

Valid requests prevented from producing invalid outcomes across sessions

Decisions based on what a session is doing, not just what a single request contains

WAFs detect. Impart controls what requests do.

The Impart Approach

Allow. Block. Modify. At the point of execution.

Step 1

Request intercepted inline at the application layer —

before your app processes it

Step 2

Behavioral analysis evaluates every signal against full session history —

payloads, identity, and prior requests — against 200+ detection tags

Step 3

Decision applied before execution —

allow, block, or modify at the point of enforcement

One runtime engine. 
Every request — web, API, and agentic.

"Impart is my pick to lead the next wave in application security tooling by leveraging usage (and other) context for decisions and making it visible to both security teams and developers. This unifies two themes in security today: Shift Left and Protect Right."

"I have a sophisticated app sec team, and they regularly complain about how limiting form-based rule builders are. They will be pumped to hear about the ability to build more sophisticated rules via code. Same with dynamic runtime lists. The LLM-powered rule explainer is also pretty cool. It is gen AI that is actually useful, as opposed to framing in another gen AI chatbot and calling it a day."

FAQ

Shift left moves security earlier in the development lifecycle, focusing on finding vulnerabilities before code ships. Runtime security operates after deployment, inline in the path of live traffic, detecting and blocking threats as they happen. A runtime protection platform is the layer that catches what shift left cannot: threats that have no pre-deployment signature, behave like legitimate traffic, and complete in milliseconds.

AI agents pursue goals across sessions, probe multiple surfaces simultaneously, and adapt continuously. Stopping them requires inline enforcement at the origin, behavioral detection that models intent across sessions rather than matching signatures, and a shared data layer across every surface so a single agent cannot get a clean slate by switching attack vectors. That is what a runtime protection platform is built for.

A runtime protection platform replaces a WAF by combining behavioral detection, inline enforcement, and shared context across Web Apps, APIs, AI Apps, and LLMs on one data model. Impart replaces the detection model entirely, not just the interface.

Runtime enforcement is the ability to detect and block a threat at the moment the request is made, inline in the path of live traffic, before it reaches your application. It is distinct from detection-only tools that observe traffic and alert after the fact, and from shift-left tools that look for vulnerabilities before deployment.
