Overview
CRITICALSTART provides Managed Detection and Response (MDR) services that help enterprises detect threats and stop breaches by resolving every alert. Its platform uses a Trusted Behavior Registry to classify alerts as known-good or unknown behaviors, ensuring analysts only investigate genuine threats. The service combines automated alert triage with human analysis through a transparent platform and mobile apps on iOS and Android. It supports integration with a wide range of security tools from partners like Blackberry Cylance, Carbon Black, CrowdStrike, Devo, Microsoft, Palo Alto Networks, SentinelOne, and Splunk. The company’s goal is to reduce security risk for customers by resolving every alert and preventing breaches.
