Overview

Appcanary monitored the software installed on customers' servers and alerted them when a version had a known vulnerability. It was sold as three products — an API, a server agent and monitor alerting — alongside a public vulnerability browser and the isitvulnerable.com lookup. The team joined GitHub and the service stopped operating on 1 June 2018.

Strengths and trade-offs

Strengths

  • Agent watched servers for software with known vulnerabilities
  • Sold as three parts: an API, a server agent and alerting
  • Ran a public vulnerability browser and isitvulnerable.com
  • Maintained its own vulnerability database, later used by GitHub

Trade-offs

  • Shut down on 1 June 2018; new signups stopped in January 2018
  • Vendor itself points buyers to GitHub Security Alerts and others
  • Captured text is a blog, so features and limits are undocumented
