Where Horizon3 and Parameterdiffer.

NodeZero attacks your network from inside. Parameter attacks the software you ship, on every release.

[ how it works ]

Continuous pentestingin three steps.

[ coverage ]

One platform for code, cloud,and dependencies.

Autonomous pentesting platforms differ most in where they look. Parameter is built for the application layer and the supply chain around it.

Web apps and APIs

Authentication, authorization, and business logic on the running application, tested as different users. Findings scanners cannot reason about: skipped steps, swapped identifiers, replayed requests.

Every pull request

An AI reviewer on GitHub, GitLab, or Bitbucket flags exploitable issues as inline comments before the code is merged. The agents review more than 10,000 pull requests a day.

Cloud infrastructure

Misconfigured buckets, permissive IAM, and exposed services across AWS, Google Cloud, and Azure, with attack paths traced to your data and a Terraform fix for each.

Dependencies and secrets

Vulnerable packages flagged only when your code reaches the vulnerable path, and leaked keys caught in commits and git history before they ship.

[ definition ]

Why teams look for a Horizon3 alternative

Most teams that evaluate Horizon3 and Parameter are deciding which attack surface they need covered. NodeZero tests the network, the credentials on it, and the paths an attacker moves along once inside. Parameter tests the software itself: the web app, the API, the cloud it runs on, the code, and the packages it depends on, on every release, with every finding proven exploitable before it reaches you.
