Featured Reviews

S. M. Rabiul Islam - PeerSpot reviewer
Is an easy, user-friendly solution that provides strong email security
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 keeps the mail inside the system unless it is deemed okay, and then can be sent to the client.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Quotes from Members

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

Pros

"It was easy to learn the product."
"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. 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."
"It provides security to both on-premises and Azure infrastructures."
"It has a really nice web-based administration console."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"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."
"The security features provided by Microsoft are robust."
"We use the solution to receive emails. We do not use the calendar function as our clients are slow adaptors to the latest features."
"We can migrate seamlessly without any disruptions to our operations."
 

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."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"It would be helpful for customers if Plan 1 features were included with EOP."
"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."
"The product's end-of-life cycle could be extended."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"The reporting needs a little bit of improvement."
"The tool's classification for bulk email is cumbersome."
"Microsoft has some training portals, but more could be developed."
 

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 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."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"Apart from the license fee for the solution, there are no additional costs."
"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 should reduce the cost."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"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."
