description: >-
  Epsagon was an observability and application performance monitoring (APM) company,
  founded in 2017, that provided automated distributed tracing for serverless and
  containerized applications — AWS Lambda, Node.js, Python, Go, .NET, Ruby, and Java —
  correlating traces, metrics, and logs to help teams identify and fix problems fast
  without manual instrumentation. Epsagon was acquired by Cisco in 2021 and folded into
  Cisco's observability portfolio, after which the product was sunset. The epsagon.com
  developer surface (docs, dashboard, and API subdomains) no longer resolves. Its
  surviving public footprint is the github.com/epsagon organization and the first-party
  instrumentation SDKs still hosted on npm, PyPI, RubyGems, Go modules, NuGet, and Maven
  Central. This profile captures that remaining, verifiable footprint.
