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."

"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."

"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."

"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."

"The product's most valuable feature is third-party integrations."

"The initial setup was easy. The configuration process is very straightforward."

"The pre-set policies and configuration analyzer are the most valuable features."

"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."

"The email policy configuration options in Microsoft EOP are satisfactory."

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."

"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."

"Our Exchange system is very locked down and secure, yet we still got hacked."

"Online Protection has an issue in that it doesn't provide an option to stop impersonation."

"When the product is being updated, it changes some of the setups. The support team is also not good."

"Some features, like encryption, are not available."

"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."

"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."

"The tool's classification for bulk email is cumbersome."

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."

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

"It's a high price."

"The product is expensive."

"The price of Microsoft Exchange Online Protection is reasonable."

"The tool's pricing is excellent."

"The solution is expensive but is backed by Microsoft's reputation."

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

"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
