Signal Sciences

aid: signal-sciences
name: Signal Sciences
description: Signal Sciences is a web application and API protection (WAAP) company whose Next-Gen Web Application Firewall
  (WAF) and Runtime Application Self-Protection (RASP) defend web apps, APIs, and microservices against the OWASP Top 10,
  account takeover, and malicious bots without the tuning burden of legacy WAFs. Founded in 2014 by Andrew Peterson, Nick
  Galbreath, and Zane Lackey and backed by CRV, Index Ventures, and others, Signal Sciences was acquired by Fastly in October
  2020 for approximately $775M and is now sold as the Fastly Next-Gen WAF. The product retains its own control plane and REST
  API at dashboard.signalsciences.net/api/v0, which remains live for existing customers and lets developers programmatically
  manage corps, sites, requests, events, custom signals, rules, redactions, lists, rate-limited sources, thresholds, virtual
  patches, and workspace alerts. Product documentation now lives on the Fastly developer documentation site.

  description: 'The Signal Sciences Core API (now the Fastly Next-Gen WAF control-plane API) is a REST API served at https://dashboard.signalsciences.net/api/v0
    that lets developers manage the Next-Gen WAF programmatically. Resources are organized under a corp then site hierarchy
    and include Agent Keys, Agents, Custom Dashboards, Custom Signals, Events, Header Links, Lists, Rate Limited Sources,
    Redactions, Reports, Requests, Rules, Simulate, Thresholds, Time Series, Virtual Patches, Workspace Alerts, and Workspaces.
    Authentication is token-based (a session token obtained from POST /auth, or a personal API access token). Responses are
    JSON; errors use a {"message": ...} envelope.'
