Alert Logic is the industry’s first SaaS-enabled managed detection and response (MDR) provider, delivering unrivaled security value.

Our purpose-built technology and team of MDR security experts protect your organization and empower you to resolve whatever threats may come. Founded in 2002, Alert Logic is headquartered in Houston, Texas, with offices in Austin, Cardiff, London, and Cali, Colombia. Critical Watch® has been a provider of security technology for many years.
