Cellopoint Defender for Microsoft 365 (Cellopoint Defender) is a cloud-native email security solution designed to enhance the email security and data loss prevention (DLP) capabilities of Microsoft 365 (M365) and Exchange Online. It effectively blocks M365-missed threats such as phishing, ransomware, and business email compromise (BEC) attacks, while also providing false positive email correction for M365. Additionally, it features an automated investigation and remediation (AIR) mechanism to improve threat response efficiency and leverages warning banners for real-time user education, helping enterprises mitigate email-based threats.

 Beyond threat protection, Cellopoint Defender strengthens data loss prevention by detecting outbound emails containing sensitive information and enforcing audit workflows. This ensures that organizations comply with security policies and regulatory requirements while preventing intentional or accidental data leaks.

 Seamlessly integrating with M365 via API, Cellopoint Defender requires no changes to MX records or email routing and can be deployed within minutes. Leveraging artificial intelligence (AI) and machine learning, it continuously learns an organization’s normal email behavior and analyzes sender identity, intent, and behavior to detect advanced and targeted email threats. Cellopoint provides cutting-edge cloud email security solutions and has been recognized by leading global research institutions, making it the only vendor in the Asia-Pacific region to be listed in the Gartner 2023 Market Guide for Email Security.
