  Nisos is a human risk intelligence company, founded in 2015 and headquartered in
  Alexandria, Virginia, that combines analyst-led investigative tradecraft with an
  AI-assisted platform to help enterprises detect, investigate and mitigate threats that
  originate with people. Its Managed Intelligence services cover executive protection and
  digital exposure, employment and hiring fraud, insider threat, third-party and supply-chain
  intelligence, threat landscape assessment, OSINT monitoring and adversary attribution
  investigations, drawing on surface, deep and dark web collection. Its Ascend platform
  productizes that tradecraft for client-led use, shipping Executive Shield and Insider
  Threat Intelligence modules with continuous monitoring, PII removal, risk analytics and
  dashboard reporting. Nisos sells enterprise-only through a demo request; it publishes no
  developer portal, no API reference and no machine-readable contract, though the Ascend
  console does call a live, credential-gated external API host of its own.

  name: Nisos Ascend External API
  description: >-
    Credential-gated HTTPS API behind the Nisos Ascend human risk management platform. Its
    existence and base URL are established from Nisos's own production build: the Ascend
    console's configuration module (ascend.nisos.com/assets/api-urls-*.js) declares
    EXTERNAL_API_URL as https://api.ascend.nisos.com and API_URL as
    https://platform.ascend.nisos.com. The external host is an AWS API Gateway that answers
    every anonymous request — root, control path and /.well-known/* alike — with HTTP 403
    {"message":"Forbidden"} and x-amzn-errortype ForbiddenException. Nisos publishes no
    reference, no OpenAPI and no authentication documentation for it, so no operations,
    parameters or auth scheme are recorded here. Listed as a measured, gated surface.

    Nisos runs a live external API for its Ascend platform at https://api.ascend.nisos.com
    — named EXTERNAL_API_URL in the Ascend console's own production JavaScript — but it is
    reachable only with tenant credentials, answering every anonymous request including
    /openapi.json with HTTP 403 {"message":"Forbidden"}, and Nisos publishes no developer
    portal, API reference or specification anywhere on its 144-page public site.
