Nisos

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.

Nisos publishes 1 API on the APIs.io network. Tagged areas include Threat Intelligence, Human Risk Management, Insider Threat, Executive Protection, and OSINT.

Nisos’ developer surface includes engineering blog, support, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/nisos: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

  detail: 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.
