Barracuda Email Security Gateway
Good combination when using their other products like an incident response. When using automated workflows, this makes creating sender policies a breeze. Unfortunately, this can also be done too well as it may filter out valid emails and to resend or place them back into users' mailbox isn't an easy thing to do even if you attempt to resend through the Email Security Gateway.

The product works great when I have to quarantine a mass email attack. Seems students are always susceptible to email base attacks, we are no different, but when one occurs on a mass email basis I can very easy and quickly block/quarantine those emails either by sender, domain, or URL or all three if need be. We have played with the data loss component but it is hard to do anything but "monitor" because there are way too many false positives. Such as with SSNs and bank routing numbers, but I figure any solution provider would experience the same problem. However, even with monitor and notification only, it is useful to make our users aware they are potentially sending personal information.

Pros
Barracuda Email Security Gateway
- ESS has a simple interface for both users and administrators.
- The "Manage Quarantine" button in each email is a direct sign-on link, so users don't have to remember their password to manage their quarantine (this is GOLD, Jerry!).
- The baseline functionality (catching spam/malware/phishing/malware attachments/malformed PDFs etc) is super-solid, with few false positives and few false negatives.

- Provides a simple but strong policy format for users and computers
- Fairly light agent installed on end-points

Cons
Barracuda Email Security Gateway
- You need to take time in adding your contacts to a whitelist so that you don't miss an email.
- I recommend changing the time interval; Barracuda notifies you that you have quarantined emails as we were only getting 1 per day and we missed some urgent emails.
- The quarantine folder is web based, we'd prefer it to have been an add-in for Outlook.

- Wish I could customize the notification emails more, like including html code to personalize and highlight messages that my end users see when an item is flagged.
- Wish there was a word or phrase component to block/flag emails as I can with files, links, senders and domains.
- Automation of the BEC list would be a plus...such as pulling in an OU or security group so that I do not have to do manually perform this task.
- We have multiple TrendMicro products. Thus it would be nice to have one dash board to "see" or login at least for ApexOne, CAS, etc.

Only a 9 if the product become completely unaffordable. Covid-19 has adversely affected Higher Ed budgets, if that should happen I would lobby hard to find cuts elsewhere...TrendMicro CAS is a necessary tool for any business to have!

So far we have had limited problems the one's we have had we can attribute to poor user judgement not our gateway failing. One of the best features is the Barracuda is intuitive to choices we make on blocking or rejecting emails which is a great feature. lessens are need to repetitively enter the same information

Once Cloud App Security is up and running there is no need to do anything additional. The program will begin protecting all the environment immediately and end results are proven. All notifications come to the administrator email to verify and mitigate a response and check the endpoint if necessary. Very easy to use.

The WebUI is the only piece I find lacking on the Barracuda ESK. Its is not the fastest and is fairly utilitarian in its approach. The Outlook plug-in, while not in wide use here, causes zero slowdown in Outlook or the Barracuda ESG.

Barracuda customer support is great. Most of the time when I can an actual tech support representative answers, not some person that will just take a message. If one is not available I will receive a call back in a very short time.

Trend Micro Cloud App Security’s support has been highly competent and thorough when we have needed their assistance. Their support has been quickly dispatched, both through telephone and Email, while answer our questions and providing the “inside baseball” answers we have wanted when discussing the why and how of certain issues. When it came to implementation, their support sat through us as we deployed agents and took us on an adventure few implementations have.

Barracuda integrates well with Office 365 and mail flow is great. It was the first solution we found that was part of a greater suite to fit all the requirements we had. With the Email Security gateway being in the cloud, it required no extra hardware but also nothing new installed on an endpoint as some solutions require.

To date we had only utilized Symantec Small Business Suite for all of our antivirus needs. We had only moved to the cloud environment during the summer of 2020, and after doing so I'm not sure that I would ever change from Trend Micro Cloud App Security. The cost and features all are a great fit for the small to medium-sized business such as ours.

Return on Investment
Barracuda Email Security Gateway
- Allows us to set it and forget it. We don't have to worry about patch or upgrade to a newer version. Barracuda does it all for us.
- DLP has been great. That's a risk which is hard to monitor but Barracuda does it effortlessly.

- CAS gives us peace of mind knowing the file systems we rely on in the cloud are protected the same way they would be if they were sitting in our office. This leads to a reduced risk of downtime that could otherwise limit us from being able to properly support our customers.
