  Efflux (Efflux Systems, Inc.) is a Baltimore, Maryland cybersecurity company
  founded in 2014 that operates a near real-time asset intelligence and
  attack-surface platform. Efflux delivers fresh intelligence about the assets
  of organizations, networks, and services — offered as a one-time Asset Map,
  scheduled monitoring, or on-demand custom scanning. Its differentiator is
  radical transparency: rather than opaque risk scores and surface-level
  abstractions, Efflux records and exposes every scan it runs, every asset it
  discovers, and every attribution it makes, so teams can see what was found,
  how it was discovered, and why it matters — raw information and formatted
  insights side by side. Data is accessible via export, download, share, and a
  programmatic API. The company is backed by 500 Global, Granite Hill Capital
  Partners, TEDCO, and Three Tree Ventures, and is currently in early access
  with a public waitlist.
