Instantly blocked and reduced our spam emails
The solution has to improve in a very specific way. When we allow our customers to send or scan email through our Barracuda Email Security Gateway, we are permitting their email server IP address, but not any domain. One of our customers has an email server where they are hosting five domains within their server. They are sending and receiving email through that server by using Barracuda Email Security Gateway. Therefore, we allow their IP address to send email through our Barracuda Email Security Gateway, then we declare MX for receiving email on behalf of our customers. After receiving the email, we deliver it to the specific IP address of the customer. Since we are only allowing the IP address, if an incident happens within a customer's email server or an email server gets compromised, then it starts sending spam. That creates a huge problem for the solution as it allows all emails because the customer's IP address is allowed to relay email through our Barracuda Email Security Gateway. Barracuda should add an option where it can add multiple domains, such as abc.com, bbc.com, and cbc.com. Therefore, this domains' emails will be allowed and other domains' emails will not be relayed through Barracuda Email Security Gateway. Whereas, if you allow the IP address, then any of the domain's emails will be relayed through Barracuda Email Security Gateway. That is the drawback that I have observed. So, Barracuda should work on this.

Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Quotes from Members

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

Pros

"It can scale."
"The client has the option to blacklist or whitelist any email address or domain based on the sender and recipient filters. If they want, they can restrict any IP addresses so email won't be received from those IP addresses."
"It catches a lot of things and has the ability to add domains as well as add senders and update their things."
"The security protection is the best and it's GUI is user-friendly."
"Before this solution, we didn't have any separate feature for protecting our emails. We used to only have a firewall but now we have email security. It has a graphical interface and we can see the log every time. We can see that the performance is fine."
"It is an excellent, intelligent solution that provides maximum security from email attacks."
"Great at blocking spam."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"The technical support is good and quick to resolve issues."
"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"Microsoft Defender for Office 365 is a stable solution."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
 

Cons

"We would like to have a local support center in India so that they are operating in the same time zone and speak the same language."
"False positives have given us issues."
"Few customers require an on-premises fabric ATP box for attack detection and response."
"There is room for improvement in the management of multiple domains."
"There's a bit of configuration work that's needed with the DNS service provider, but other than that, everything else should be very smooth."
"Spam is not always detected, and it should be more automated. We have seen that some emails are allowed by these emails, which are then stopped by Microsoft."
"We are using the tool’s 400 model which does not offer accurate spam detection. We have also had performance issues with the tool."
"Barracuda Email Security Gateway should include ATP in the next release."
"You should be able to deploy Defender for every subscription without the need to add servers."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"Several simulation options are available within 365, and the phishing simulation could be better."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"Microsoft Defender for Office 365 should be more proactive."
 

Pricing and Cost Advice

"This is one of the major points for integrating this solution in any organization. Barracuda Email Security Gateway needs to make it a bit more tolerable for customers because it is increasing every year. They should create a plan for reducing the cost."

"The price of Barracuda Email Security Gateway is approximately $17 per user annually."
"The pricing is normal. Considering its popularity, it's not overpriced."
