Defendermate

Defendermate is a cybersecurity company that has developed a platform focused on combating phishing attacks through artificial intelligence. It primarily serves managed service providers (MSPs) and managed security service providers (MSSPs), offering them a multi-tenant solution to protect their clients. The platform integrates with Microsoft 365 and Google Workspace to analyze and triage suspicious emails that bypass initial security filters.

The core of the service is its AI-powered analysis engine, named GERT, which examines reported emails for malicious indicators. This system automates the process of identifying threats, removing them from all user inboxes within a tenant, and providing detailed reports. This automation aims to significantly reduce the time security teams spend on manually handling phishing incidents, from hours to minutes. Defendermate's business model is subscription-based, designed to be scalable for MSPs managing multiple clients.

The company was founded in 2023 by Adam Bleiman, whose background includes experience as a director of product management, and Jonathan Tyburski, who previously worked in enterprise security and as an IT administrator. The founders identified a gap in the market for an effective, automated phishing response tool specifically designed for the MSP channel.
