Barracuda Reviews, Ratings & Features 2026 | Gartner Peer Insights

Gartner defines an email security solution as a product that secures email infrastructure. Its primary purpose is to protect against malicious messages (phishing, social engineering, malware) or unsolicited messages (spam, marketing). Other functions include email data protection; domain-based message authentication, reporting and conformance (DMARC); investigation; and remediation through a dedicated console. Email security solutions may also support nonemail collaboration tools, such as those for document management and instant messaging. Email security tools protect an organization’s email from spam, phishing, malware attacks, account takeover and data loss. They may provide capabilities for data loss prevention, encryption, domain authentication and security education, as well as advanced protections against business email compromise. Email security platforms give cybersecurity teams visibility into email-related security incidents, support investigation and automated remediation, and enable management of both inbound and outbound email delivery. Email security solutions often integrate with other network, identity and endpoint security controls, and may also support collaboration tools and email relay capabilities.

I selected Barracuda because its Customer Service is available on call, and I don't have to go through automated options to select. Its customer service reps are very responsive and most of the time are thorough in troubleshooting and explaining the cause of the issue.

What worked well: Overall it's a good product, the biggest issue we experience as a printing company is that not all of our customers have a registered domain, so a lot of real important emails are blocked by DKIM. On the other side of that, large companies that are used for third-party purposes like signing documents often get through the filter and are caught on the back end by users, even when it's sent in bulk like format it sometimes gets through. Overall, when integrated with proper user training to identify phishing attacks, it's a good system that I trust and will likely renew when the time comes.

We've been a Barracuda customer for many years in our organisation and have approximately 80 users across three sites in three different countries under a single Microsoft tenant. It integrates cleanly with Microsoft 365 and has been stable and reliable over the years with only limited intervention required by IT when dealing with quarantined items and false positives.
