Barracuda Networks has launched Barracuda Integrated Email Protection, an Integrated Cloud Email Security (ICES) product aimed at organisations using Microsoft 365 and Google Workspace, as email-borne attacks increasingly incorporate AI-driven techniques.
The company said the product is designed to detect and remediate threats across the email attack lifecycle, including post-delivery “clawback” of malicious messages and explanations of security verdicts across Microsoft 365 and Google Workspace.
The announcement coincided with new Barracuda Research findings from a controlled Red Team simulation. Barracuda said a single phishing email led to identity theft, multifactor authentication (MFA) bypass, persistence and endpoint compromise within five minutes, illustrating how quickly email incidents can move beyond the inbox.
In the same research, Barracuda said “one in seven” compromised accounts is being used to launch additional attacks, and argued this is likely to increase as threat actors automate activity using AI.
According to Barracuda, Integrated Email Protection is built on its BarracudaONE platform and is intended for single- and multi-tenant environments, including use by managed service providers. The company said it correlates signals across domains including email, identity, network, data and applications to support investigation and response.
“Email is no longer a human-centric communication platform; it’s an operational fabric where humans and AI interact, making it a much bigger target and amplifying the speed, scale and impact of attacks when threats go undetected,” said Rohit Ghai, chief executive officer at Barracuda.
Barracuda said additional capabilities include a unified quarantine that consolidates Microsoft-quarantined emails into Barracuda for review, integrated reporting on threats stopped before and after delivery, and an AI assistant, Bailey, intended to provide explanations for decisions and enable teams to review or reverse actions.
The company said the product can be deployed via an API-based architecture without Mail Exchange (MX) record changes and without disrupting mail flow.
Scott Harris, chief information officer at TriRx Pharmaceuticals, said the updated capabilities provided greater confidence as email threats continue to evolve.
