Featured Reviews

Provides comprehensive email security management, effective in detecting a wide range of email threats
The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails. This means Abnormal Security would assess emails before they reach my inbox, even if it happens slightly after Microsoft's initial scan. Currently, the process isn't seamless. Microsoft analyzes emails and delivers legitimate ones to my inbox. Abnormal Security then scans these delivered emails, and if flagged as malicious, they disappear. This creates a problem for our ticketing system mailbox, which is a third-party service. Emails sent to the ticketing system address are automatically forwarded by Microsoft. However, if these emails are malicious, Abnormal Security only cleans them from my Outlook mailbox after they've been forwarded. Since we primarily rely on the ticketing system and not the Outlook mailbox, these malicious emails still reach the ticketing system.

Secures email by identifying threats and managing email policies effectively
The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled. Our investigation in any incident or mail is very useful as it provides all details about incoming mails, enabling thorough review and detection. The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails. The Impersonation license utilizes AI tools. Sometimes some phishing mails are reported as phishing, but they are not actually phishing mails. They are detected due to certain words and languages that appear suspicious but were generated by AI tools. Everyone or an advisor may use it for their own purpose or learning, even though it indicates that the mail detected is phishing when it's not.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"I would recommend Abnormal Security."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"Abnormal Security's AI capabilities are what we like most, as they can categorize and classify the emails, and based on the context of the email, understand if it's a graymail, a bulk mail, or a phish."
"I have never encountered any stability issues with Abnormal."
"I like Abnormal's threat protection with auto-remediation, but I also love its abuse mailbox feature, which automatically responds to the end user. That feature has a super-valuable security component and helps improve the user experience."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"It is very simple to whitelist addresses."
"Its backups are valuable."
"It is lightweight, and we can filter all of our inbound and outbound emails. We have controls for rate control, quarantine, and tagging. We can see whether an email is a spam email or a phishing email."
"Great at blocking spam."
"Barracuda Email Security Gateway has positively impacted my organization by reducing security incidents and stopping attacks targeting us."
"Barracuda Email Security Gateway is very simple to use."
"It not only tackles spam effectively but also incorporates advanced features like ATP and active features which ensures a comprehensive and adaptable email security solution tailored to their heterogeneous environment."
"The solution helps us to block some blacklisted emails."
 

Cons

"Abnormal should add more automatic reports. I have an open request to our account team for more notification and report types that can be sent automatically. For example, they have an awesome report that gets sent weekly, and I also want them monthly, so I don't need to do so much adding up when my director wants numbers over time."
"One feature I'd love to see is outbound scanning."
"There could be more selectable options and more granular selections available."
"I would like to have the ability to customize the auto-remediation feature."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"The biggest pain point for us is the lack of support for on-premise email systems."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"There could be more selectable options and more granular selections available."
"We are using the tool’s 400 model which does not offer accurate spam detection. We have also had performance issues with the tool."
"The reporting can be improved."
"Spam is not always detected, and it should be more automated. We have seen that some emails are allowed by these emails, which are then stopped by Microsoft."
"The solution should include an improvised anti-phishing feature, since it blocks certain genuine emails."
"There is room for improvement in the speed of the interface, specifically the cloud interface, is a bit slow."
"My customers were sending OPT bulk emails and Barracuda Email Security Gateway was not able to handle it. We have to go with another different solution, such FortiMail for the task. We are implementing these combinations of the Barracuda and FortiGate, for email security. The FortiGate FortiMail security gateway we use to send only the bulk email, not for receiving emails."
"I have noticed that it takes a little time to get familiar with after deploying and some tweaks need to be done as things come up."
"There are some times when legit emails are trapped on Barracuda and we are unable to get that information unless we actually log on to the network to find out."
 

Pricing and Cost Advice

"The license is based on the user count, so the number of users that have an email address in the organization."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"I rate the price of Barracuda Email Security Gateway a ten on a scale of one to ten, where one is low price and ten is high price."
"The solution is priced low. We have received a good price discount here in Sri Lanka. There are additional licenses we have to purchase a license for the ATP."
"We paid for an annual license."
"We typically purchase a one or three-year license for Barracuda Email Security Gateway."
"It is an expensive solution and I would rate it 5 out of 10."
"Compared to other products, this solution is quite affordable."
"The regular pricing was initially very reasonable, but three years ago, Barracuda revised their price list and SKUs, resulting in a significant doubling of the standard prices."
"The pricing for the product is fine."
