Barracuda Email Security Gateway and Microsoft Defender for Office 365 compete in the email security category. Barracuda has an upper hand in customization and threat blocking, while Microsoft Defender excels in integration and broad security coverage.
Features: Barracuda Email Security Gateway offers advanced threat protection and spam filtering, with customizable options like attachment filtering and domain whitelisting. Microsoft Defender for Office 365 includes safe links, attachment scanning, and phishing protection, with strong integration into Microsoft's broader suite.
Room for Improvement: Barracuda users report issues with inadequate spam detection and lack of automated updates, suggesting a need for improved domain management and better integration features. Microsoft Defender could enhance its threat detection against sophisticated attacks and improve pricing for smaller businesses.
Ease of Deployment and Customer Service: Barracuda is flexible across on-premises and hybrid cloud environments but has complex deployment and support delays. Microsoft Defender integrates seamlessly in cloud environments, though initial configuration can be complex. Support for both is satisfactory, but Barracuda's is sometimes regional while Microsoft could improve proactive communication.
Pricing and ROI: Barracuda's pricing is considered high but offers ROI through fewer incidents and reduced operational impacts. Microsoft Defender is noted for high costs, particularly around E3 and E5 licenses, yet provides comprehensive features that justify expenses for larger enterprises. Both solutions offer ROI through enhanced security and reduced threat impacts.

I have not experienced any downtime, crashes, or performance issues because of Defender.
The solution is stable, as we have been using it for the past two years.
When we add mails to email secure Sender Policy Authentication with extended options, all mails must pass this Mail Security Gateway.
Sometimes there are false positive emails coming through, so they should improve further on detection technologies and techniques.
If it's considered a phishing email, it should be blocked for all users, not just some.
The main area for improvement is simplifying the implementation and rollout process.
Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published.
There is a different console for different things; I just want one consolidated console.
Compared with others, Barracuda Email Security Gateway is cheaper.
We've likely saved 30% of costs.
The standalone P2 can feel more expensive if enabled for all users, and the licensing might be somewhat confusing with terms like P1 versus P2 and feature dependency.
Money-wise, it is a part of the Office 365 suite, making it slightly more expensive compared to Trend Micro.
The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails.
The most valuable feature of Barracuda Email Security Gateway that I have found is advanced threat protection.
It ranks the threats and allows us to prioritize those hitting us the hardest, such as email threats.
It provides end-to-end visibility on email threats such as phishing, extending beyond Exchange Online Protection.
The value of the DLP feature is significant to us because we have internal data, sometimes sensitive, and the users may not always be aware of security and privacy, which might lead them to send out information mistakenly to external parties.
