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.

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

"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"The initial setup was easy."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"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."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"They have something called Pattern Filtering, which has been a godsend... For example, if I don't want any email to ever come through that has the term "hot dog" in it, whether it be in the subject, the title, or anywhere else, I can immediately block such emails, company-wide. That has saved me so much time."
"Every client that uses it experiences a productivity boost. If somebody has to filter through 150 or 200 emails a day to find the 30 good ones, that's inefficient. If they're using SpamTitan it's making them more efficient because they don't have to go through all the junk."
"If all you have is a solution that looks at every piece of email and applies the same types of rules, you don't get a very smart solution. Whereas, if you can do it per mailbox or per domain, like you can with SpamTitan, that means you are effectively able to configure it almost per-user, which is great."
"I like SpamTitan's email sandboxing. It is very effective and blocks almost 99% of spam. It also has zero-day threat protection."
"We're now using SpamTitan Plus. It has an extra feature so that if you receive an email with a link, it goes to the TitanHQ server and that link is also checked. That is probably the best feature."
"What I like the most is the filtering and the granularity with which you can really zoom in on the spam that's coming in and configure it exactly so that what you don't want is blocked."
"[One of the] things that make[s] it really attractive to end-users... is their ability to manage their own spam queues via the reports that SpamTitan offers. It allows them to determine what is spam and what isn't."
"The overall intuitiveness is really good. We have been able to run reports, set up quarantine emails, and integrate with our Exchange server. That has all been extremely straightforward."
"The technical support services are excellent."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"The solution provides protection with its Email Track Records and Machine Manual features."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
 

Cons

"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."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The pre-sales cost calculations could be more transparent."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"If I had to actually find a negative, it would be the speed. I wish that the interface were faster. We have very fast internet, but there is definitely some sluggishness between pages on the interface. Does that deter me? No. I just wish it were quicker."
"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."
"There was a situation in which I needed to change the cloud server. From SpamTitan, I had to specify which server we were on for the integration into Office 365 and I actually only found that out because there was a problem. It would have been better if they had advised us of that first."
"Sometimes, things can get caught back in spam that you had previously released. Without going in, releasing the whole domain, and opening it up, since you don't want to do that often because the company can get infected as well, I have a couple of things that I previously released show back up again. I don't understand why this is happening, but I would like to know why it happened, e.g., did an algorithm change? It is important to know if I released an email last week why it was caught in spam the following week."
"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."
"The only downside is that there is a delay when we're waiting for a report to be generated."
"The way it rates what is spam and what is not spam can be improved, although that is true with every system."
"It's been the same interface for ten years and some things are hard to find, even after using it for years."
"The solution's pricing could be improved."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The product's pricing could be more flexible."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"I know that the product is incredibly expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"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."
"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."
"We are on a per-user or per-mailbox monthly subscription. We are happy with the price of the solution. When comparing it to other solutions it is much cheaper."
"Cloud-based solutions charge per mailbox, which isn't ideal sometimes. A company could have 300 total mailboxes and only 50 in regular use, but they would have to pay the same for all of them. I want a cloud-based solution that gives a price based on the volume of email traffic."
"The price and the licensing are fair, allowing us to make a margin on the product. We paid a one-time fee for the sandboxing feature; apart from that, it's just the standard licensing."
"The pricing is great, but it has been increasing on a yearly basis. It is now close to that of Microsoft solutions. If it continues to increase, then clients may need to migrate to a different solution."
"This pricing is absolutely fine and it's never been an issue of it being too expensive."
"But the most critical factor was cost-effectiveness. SpamTitan was much cheaper than Barracuda and offered the same value."
"Price-wise, this product is very compatible with our budget."
"The price was great compared to other solutions that we looked at the time."
"Trend Micro is an expensive solution."
"I rate Trend Micro InterScan Messaging Security’s pricing a seven out of ten."
