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 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."

"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."

"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."

"Overall, I think it's really a great product."

"The most valuable feature is the ease of administration. Other solutions require complex administration, but Microsoft Exchange Online Protection is easier."

"Microsoft Exchange Online Protection (EOP) is used essentially for email filtering, acting as an anti-spam and security product for email."

"The solution's stability is very, very good. I didn't face any problems in the last year."

"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."

"You can use the product to create special accounts."

"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."

Cons

"The product must improve the features associated with creating a blacklist."

"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."

"If the price were lower, perhaps we could purchase our own."

"Only one to two accounts were compromised, and for that, Barracuda blocked all incoming and outgoing mails."

"It doesn't protect against everything. We do need protection for, for example, endpoints."

"Some of the searchability when looking for specifics in Exchange logs is tedious."

"They should specify the difference between Defender for Office 365 and Exchange Online Protection."

"The tool is not 100% stable."

"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."

"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."

"It would be helpful for customers if Plan 1 features were included with EOP."

"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."

Pricing and Cost Advice

"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 solution is a bit expensive."

"The solution is priced high and could be less expensive compared to other solutions."

"The price could be lower."

"The product's pricing is competitive for the US market."

"The solution falls on the higher or more expensive side of the spectrum."

"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."

"Online Protection is fairly expensive."

"Apart from the license fee for the solution, there are no additional costs."

"The product is expensive."
