A highly scalable and easy-to-learn product that blocks phishing and spam emails
The product must improve the features associated with creating a blacklist. Currently, to add a content block, I have to go to a different screen. It seems cumbersome. The solution sells Impersonation as a separate product. I don’t see why it cannot be in the same product like other vendors have.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Quotes from Members

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

Pros

"The most valuable feature of Barracuda Email Threat Scanner is the security it provides by delaying the delivery of suspicious emails until they can be reviewed inside the Barracuda control panel."
"The main benefit that I am getting from this solution is that it filters almost 95% of my spam mail."
"It was easy to learn the product."
"The main benefit that I am getting from this solution is that it filters almost 95% of my spam mail. Some spam mails bypass Barracuda Email Threat Scanner, but when I add those domains or addresses to the filter list, they get blocked. Some users on my premises do not understand which mail attachments or links should be opened. By filtering with Barracuda Email Threat Scanner, we are not getting any type of phishing mails. So, our infrastructure is safer, and as an IT person, I feel relaxed."
"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."
"What I like most about Microsoft Exchange Online Protection is its integration with Windows, so we have one central view for all alerts and incidents."
"It provides security to both on-premises and Azure infrastructures."
"It is useful for local users and our company because we use Microsoft 365."
"The initial setup of Microsoft Exchange Online Protection was easy."
"The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done."
"Online Protection's most valuable feature is its admin interface."
"We can migrate seamlessly without any disruptions to our operations."
 

Cons

"The product must improve the features associated with creating a blacklist."
"If the price were lower, perhaps we could purchase our own."
"We had an incident last month where the PCs of one or two colleagues, who were outside of our factory and were using a defined network, got infected by some kind of malware. From their PCs, more than 1,000 mails were produced per hour, causing spamming on our mail server. Barracuda blocked the full mail communication. Only one to two accounts were compromised, and for that, Barracuda blocked all incoming and outgoing mails. It created a great problem for other users and our office activities. Our server was blocked for three days, which we did not expect. Technically, only one or two accounts should be blocked. When a domain or IP is blocked, communication becomes tough. It may be a configuration issue at our provider's end, where there was a mistake in configuring Barracuda. It could also be a problem related to Barracuda."
"Only one to two accounts were compromised, and for that, Barracuda blocked all incoming and outgoing mails."
"The security features could be better and more secure in the next release."
"I would like to get reports about vulnerable connections from our clients with information about domains, public IPs, etc. That would be highly useful."
"The biggest issue that I experience is that Microsoft keeps moving things around, and it's very inconsistent as to where you find the information when you're trying to work on different pieces."
"The licensing can be on the expensive side, especially in the cloud space."
"The solution lacks to elaborate on its spam policies."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
"Microsoft 365 Defender and EOP policies are stable with the proper license. However, with the basic policy, it's hard to say it's stable due to configuration limitations."
 

Pricing and Cost Advice

"The solution is a bit expensive."
"Barracuda Email Threat Scanner is provided by our IT service provider, who also provides all the support. The licensing fee that we pay to our provider is $200 per month, that is, $1 per user. There is no additional cost. Before taking the subscription from our provider, I researched the market for Barracuda. The cost is between $5,000 to $8,000 for three years. After that, the same cost is there for renewal. If you have 200 to 500 users, it is better to take a subscription from a provider. If you have more than 500 users, then you can own the Barracuda server through the cloud or on-premises deployments. It is costly for a lesser number of users. If you increase the usage or the number of users, then the overall cost decreases. They can reduce the cost of Barracuda Email Threat Scanner for a small number of users. We could not and would not have used this solution if we had not got the renting or subscription option."
"The product's pricing is competitive for the US market."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
"The product is expensive."
"The solution is priced high and could be less expensive compared to other solutions."
"Apart from the license fee for the solution, there are no additional costs."
"Online Protection is fairly expensive."
"The solution is expensive but is backed by Microsoft's reputation."
