Your API Isn't Listed? Perfect.
We don't have an "integrations list" to maintain. KnoxCall proxies ANY HTTP request to ANY endpoint.
Internal APIs, legacy SOAP services, that startup tool with 3 customers - we secure them all the same way.
The services above are just what our customers asked us to highlight. Tomorrow you could be securing an API that doesn't exist today. That's the whole point.
