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."
"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."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"Microsoft EOP's most valuable feature is a shared mailbox."
"We can migrate seamlessly without any disruptions to our operations."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
"It's all running in the backend, so it doesn't affect the app functionality."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities, and additionally, the solution is easy to use."
 

Cons

"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."
"The product must improve the features associated with creating a blacklist."
"Only one to two accounts were compromised, and for that, Barracuda blocked all incoming and outgoing mails."
"I think the implementation could be more streamlined."
"The product's end-of-life cycle could be extended."
"The tool's classification for bulk email is cumbersome."
"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."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"Microsoft Exchange Online Protection is quite a difficult product."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
"They should specify the difference between Defender for Office 365 and Exchange Online Protection."
 

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."
"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."
"The solution falls on the higher or more expensive side of the spectrum."
"The price could be lower."
"It is a low-price solution."
"The product is expensive."
"Online Protection is fairly expensive."
"Apart from the license fee for the solution, there are no additional costs."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
