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.

Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.

Work hours are not lost searching through spam emails to determine which emails are legitimate
In history on the reporting graph, when you are trying to search for sender by address, it won't search by domain. I could send an email from SendGrid with my domain, but with SpamTitan, if you search by that domain then it wouldn't search it. It only searches from the field, not in the envelope field. Unfortunately, mass mailing companies, like SendGrid, send email with the form address and that completely differs from the domain envelope form address. There is no way to search for the envelope form. So, I gave them an idea to improve this filtering. For example, if I have to search an email sent by SendGrid, then I am forced to search by the recipient, then find the emails marked as spam. This is quite a huge hassle. They told me that they are aware of this and will try to add it, but they haven't added it yet. I would like to implement a secondary delivery pool for mass mailings, having an alternate pool for mass mailing lists since there is only a single mail queue with SpamTitan. For example, if 10,000 emails are being sent, then the queue will be large. Unfortunately, without a secondary delivery pool, legitimate emails will wait in the queue to be delivered to my email. Therefore, I would like to have two queues: one for everyday emails and another for mass mailings. Now, I have to decide whether to buy a second SpamTitan license just for this reason because I am very satisfied with the functionality of SpamTitan overall and don't want to use another sender's appliance for this. From 2020 to 2021, there was a huge switch in the types of spam coming in. SpamTitan's anti-spam should be enabled to catch this spam. The spam catching rate went down over the last three to four years. I think this is because spammers are evolving and using different methods to send spam emails. The phishing rate of SpamTitan is not great, even Exchange Online Protection catches phishing better than SpamTitan. The most worrying are the phishing emails. I would like SpamTitan to upgrade and improve the phishing catch rate. The sandbox of the Bitdefender engine is not working correctly. They sent me an email that they pulled it because it was not working as it was intended to work. So, they are working on this as well, and maybe the sandbox will be fixed. The sandbox is for viruses. If something goes through then it is sent to the sandbox for analysis. However, I am not using the sandbox right now. I am just quarantining this type of attachment right away.

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 Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"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."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"One of the best features of the tool is its capability to aggregate insights from different workloads, basically from the Office 365 and endpoints part."
"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."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"They are very easy to use."
"The fact that it does exactly what it says on the box is what I find most valuable about SpamTitan. They've reduced our spam by about 99 percent."
"The most valuable feature is the Link Lock, which prevents our users from clicking on links that haven't been verified."
"SpamTitan has made it easier to manage spam. When other solutions I've used quarantined something, an admin had to manually find and release it. With SpamTitan, the end-user can monitor it themselves and release their own quarantined items. It's faster and less work."
"The discovery work to resolve [issues] has gotten so much easier because we can see what's going on right at the edge of our incoming and our outgoing mail. A regular tech support dude can log in... and get a very practical view of what is going on..."
"We get reports on blocked emails. I review them weekly to see who the heavy hitters are inside the office. We need our email addresses out there to do business, so we have sales and customer service email addresses that need to be out there. Those are the biggest targets for spam. SpamTitan cuts down the amount of spam that we receive, but it's about the same as Barracuda."
"The overall system is straightforward to use, and the UI is excellent. It significantly streamlines the process of dealing with spam emails."
"It provides security for the communication between the sender and receiver. It does the encryption perfectly. We ensure that emails are sent without any security breaches. The spam catch rate at the moment is almost 100%."
"I like SpamTitan's email sandboxing. It is very effective and blocks almost 99% of spam. It also has zero-day threat protection."
 

Cons

"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 XDR dashboard has room for improvement."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"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."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"The product must provide better malware detection."
"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Email security checks contain a small number of false positives."
"SpamTitan doesn't allow you to customize the time reports are sent. Sometimes our users would prefer that it come at a certain time, like 7:00 am so they can make sure they didn't miss anything from the day before. Currently, it can come in the middle of the day and probably depends on the server's restart or the setting change."
"I believe the product is configured for the US or European market, not the Latin American market, and the scoring system is a little too strict for our market. Most companies in Latin America don't even have proper domain configuration, which can cause their emails to be filtered as spam. They might not have DMARC or SDF configuration, so we often have to change the scoring threshold to let legitimate emails through. It's not SpamTitan's fault, but the optimization isn't the greatest considering our market."
"Initially, I had some issues where we were getting emails coming in that appeared to come in from our own internal domain. My company is called M2 Systems, so our domain name is M2-corp.com. I had to get on with support twice to get them to help me mitigate or block that from happening."
"The big issue that I've had is that the length of time that an email is kept in quarantine is only seven days and, in some cases, it is not even seven days... if I had a 20-day or 30-day repository, if someone came to me and said, "Hey, I can't get this back," I could end up getting it to them from the archive."
"The stability of SpamTitan is equivalent to other email security solutions that I have previously used. Some of them have more bells and whistles that you can add. For example, inside the email subject line, you can put in the words encrypt secret, or secure. Then, it will automatically secure that email and send an email to the person who is supposed to receive it. They can identify it for themselves in a series of different Q&A questions. That is sometimes a deciding factor for clients."
"There is no plugin for Outlook, which might be of an advantage so that you can just click on a link in Outlook that takes you right to your quarantine list. It doesn't have that at the moment."
"The product's GUI, dashboard, and speed could be better."
"It's been the same interface for ten years and some things are hard to find, even after using it for years."
 

Pricing and Cost Advice

"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"I know that the product is incredibly expensive."
"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."
"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
"Its pricing is good. It's probably one of the most competitive anti-spam and anti-malware appliances out there for email. I was doing some looking around for pricing before I came to SpamTitan, and for the feature set, the price is very reasonable and competitive."
"Pricing is on par with other products, and it's reasonable."
"The price was great compared to other solutions that we looked at the time."
"Price-wise, this product is very compatible with our budget."
"I don't deal with pricing. In terms of licensing, the last I heard was that the licensing for users in SpamTitan isn't fully functioning because of some integration issues with Microsoft. I know we have more than 20% on our licensing at the moment, but the way the licensing is supposed to run makes a lot of sense for us. We are looking forward to that part getting implemented correctly."
"Everything has really been great with the pricing and licensing. In fact, we just implemented ArcTitan because everything was going so well with SpamTitan."
"We're happy with their licensing model. It was a major factor in why we chose them."
"The price of SpamTitan is reasonable. It makes sense. There is no cost for me because I'm the managed service provider. The end customer pays the cost because we sell professional services to set up the whole solution, including SpamTitan and other products. Usually, it's part of a much bigger project."
