[ how it works ]
Continuous pentestingin three steps.
[ coverage ]
One platform,every layer of your stack.
A bounty program covers the public surface researchers can reach. The agents cover the stack, including what is private.
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 HackerOne alternative
A researcher program brings outside eyes to the surface they can reach, when they choose to look, and a triage team to sort what they send. Parameter's agents test the whole stack on every release, private code and cloud included, prove each finding with a working exploit before it reaches you, and cost the same whether they find one issue or fifty.
