We are excited to introduce Levo’s Web App Scanner, an addition to Levo’s next-generation agentless discovery approaches!

Web App Scanner logs into your web application and explores it automatically, then maps the API endpoints it uses. It creates a fast, outside-in API inventory you can act on right away, without deploying anything inside your environment.

Until now, meaningful API visibility typically required one of two commitments: deploying our eBPF sensor or integrating with existing security sensors. 

Both approaches are effective, and both can take time in large enterprises. The earliest and most important step towards security i.e. knowing which APIs exist often becomes the longest stage as production approvals, organizational red tape and DevOps bandwidth delay visibility in the very environments where it matters most.

Web App Scanner changes this paradigm. By surfacing external endpoints instantly, it accelerates API Security programs and as a result API-led business growth.  

Go through the rest of this release note to understand how this approach works and how it enables software led business growth and AI adoption.

Achieve Complete API Visibility Without Agents or Integrations

The scanner signs in using a designated set of credentials and interacts with the application in a controlled, repeatable way. As the application runs through real user flows, Levo surfaces the API endpoints that are being exercised in the process.

Here’s how to get started now: 

  • You point Levo at a web application and provide a login that represents a real user.
  • Levo establishes a controlled session and explores the application paths that drive meaningful behavior.
  • As those paths are exercised, Levo identifies the APIs involved and builds a catalog of what is in use.

Web App Scanner is not a substitute for Levo’s eBPF sensor-led discovery as it remains the most comprehensive way to maintain a real-time inventory across the full API surface, including internal and non-UI APIs.

Make APIs AI-ready with Levo

Web App Scanner does not just surface endpoints. It kickstarts the full process of making those endpoints governable and safe for automation with automated security best practices. 

Levo makes APIs agent-ready by automating all downstream API Security best practices:  

  • API Documentation: Once an endpoint is discovered, Levo generates API documentation consisting of OpenAPI and Postman specifications that mirror production reality. These contracts capture the request and response shapes, status codes, authentication signals, and error patterns, so both humans and automated systems can interact with the API without guesswork.
  • API Security Testing: With the contract in place, Levo can run security validation that is specific to how each endpoint behaves in the real world. Testing is generated and executed per endpoint, including coverage for common exploit classes and access-control failures, so teams learn what the API accepts, what it rejects, and which behaviors are actually exploitable.
  • API Monitoring: Levo continuously monitors API posture and behavior so teams can detect drift, catch misconfigurations early, and maintain an accurate understanding of how endpoints behave as environments, policies, and releases evolve.
  • Real Time Protection: Production security controls like API Threat detection and API Protection are only effective if they are runtime-informed. With discovery as the anchor, Levo can enforce controls that hold up under high-frequency, automated access patterns by scoping privileges tightly, applying rate limits that reflect usage reality, flagging suspicious behavior, and rotating credentials in a way that reduces blast radius.

These are the same practical requirements Postman’s 2025 State of the API Report highlights for building agent-ready APIs: machine-readable schemas, predictable patterns, meaningful documentation, robust error handling, and controls designed for automated access. The point is not that agent readiness is a separate project. It is the natural outcome of running APIs through a mature discovery-to-governance pipeline.
