Cellopoint Recognized in Three Gartner Reports

Top 3 Email Security Challenges for Security Teams

  1. As cybercriminals constantly evolve tactics and techniques, novel attacks, including zero-day phishing, ransomware, and business email compromise (BEC) scams are on the rise in both frequency and damage.

  2. The adoption of Microsoft 365 is growing rapidly. However, relying solely on Microsoft's native email security controls could be risky as Microsoft is not 100% effective in blocking all email threats.

  3. Legacy secure email gateways (SEG) rely on rule-based detection approaches which are not effective at addressing modern advanced email attacks. SEGs are also complex to deploy and maintain.



Cellopoint Defender for Microsoft 365 seamlessly integrates with Microsoft via API and can be deployed in minutes. It uses AI-powered, cloud-native approach and combines threat intelligence, Cellopoint SOC team analysis, and false positives and missed attack reports to identify and block advanced email threats-which often bypass Microsoft and reach your mailbox.

Effectively detect M365-missed attacks

Our AI-based email security solution uses known good models to identify anomalies in sender identity, intention, and behavior. We complement Microsoft 365's native email security with comprehensive detection mechanisms including threat intelligence analysis, SOC team analysis, and user and admin reporting features, to block advanced threats like zero-day phishing, ransomware, and BEC scams missed by Microsoft 365.

Auto investigate and remediate your mailboxes

Cellopoint Defender's Auto Investigation and Remediation (AIR) automatically investigates all inboxes within your organization when a new threat is detected. AIR identifies hidden threats by comparing patterns of the new threats and based on the policies, will auto remediates them accordingly, such as adding warning banners and deleting or moving emails to the junk folder to reduce the security team’s investigation time and their burden.

Auto remediate M365 false positives

Cellopoint Defender not only scans the emails in the inbox but also scans the emails in the junk folder to detect safe emails mislabeled as spam by M365. If a safe email (false positive) is detected in the junk folder, Cellopoint will auto remediate it by moving it to the inbox and adding a low-risk warning banner. This ensures that important emails are not missed, improving the organization’s efficiency and productivity.

Provide educational warning banners

Cellopoint Defender provides recipients with contextual warning banners containing clear and concise information about potential threats, which can help increase their email security awareness and reduce organizational risks. Additionally, recipients can report suspicious emails directly through the banners, allowing for rapid adjustments to detection effectiveness and saving time for security teams.
