Reduce your API attack surface

Discover every API automatically, including those your gateways missed.

01 Comprehensive API discovery

Automatically uncover every internal, external, and third-party API across your environments, regardless of gateway presence or documentation status.

  • Advanced API discovery: Salt continuously analyzes real-time traffic to detect every API, documented or not. Gain visibility into live, legacy, and third-party APIs.
  • API details exposed: drill into parameters, auth methods, data classifications, traffic patterns, and risk posture.
  • No documentation? No problem: Salt doesn’t rely on OpenAPI specs or gateway integrations alone. It finds what others miss.
  • Context-rich filtering: slice and dice your API landscape by environment, exposure level, business unit, or risk.

02 Identify shadow and zombie APIs

Most organizations have 2x–8x more APIs than they think. That’s a huge blind spot.

  • Detect unmanaged APIs: shadow, deprecated, and abandoned APIs are discovered and flagged.
  • Protect sensitive data: unmanaged APIs often expose PII, PCI, and business-critical data.
  • Compare vs. docs: automatically validate current APIs against internal documentation and OpenAPI specs.

03 Monitor API change continuously

Discovery isn’t a one-time task. Salt makes it ongoing.

  • Track API lifecycle events: get notified when new APIs appear or existing ones change risk posture.
  • Maintain inventory integrity: eliminate drift between what’s deployed and what’s known.

What our customers are saying

“One of the solutions we considered needed our documentation of our APIs and endpoints, but that’s part of the problem. We’re sure we don’t know about all our APIs… Now that we have Salt, we’ve got a solid idea of what’s out there, and we’re protected in runtime.”

—Jason Weitzman, Senior Security Engineer, via Gartner Peer Insights
