name: Stairwell
description: Stairwell is a private-by-design threat intelligence and detection platform that gives security teams a continuously
  reanalyzed, isolated store of their own files as an alternative to crowdsourced public services like VirusTotal. Its products
  span AI triage and static/behavioral malware analysis, malware variant discovery, Run-to-Ground incident scoping, and an
  encrypted Private Vault with retroactive detection as threat intelligence evolves. Stairwell exposes a REST API at app.stairwell.com/v1
  (bearer-token auth) covering assets and forwarders, objects and detonation, sightings and variants, YARA rule management
  and ad-hoc scanning, threat reports and IOC correlation, network intelligence (hostname/IP/ASN WHOIS, cloud-provider lookups),
  plus outbound event-notification webhooks and an official hosted MCP server for read-only agent access. Added to the API
  Evangelist network from Accel's portfolio and enriched from Stairwell's public developer surface.
