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.

An effective email security solution that provides DLP, Safe Attachment, and Safe Links
If you want extensive email security, you need to purchase a Plan 2 license. Plan 1 and Plan 2 are the two plans for Microsoft Exchange Online Protection. Some customers hesitate to purchase this product because it adds some costs to them, which is necessary for them. It would be helpful for customers if Plan 1 features were included with EOP. However, they still need to purchase Plan 2 for advanced security features. One of our clients recently requested to compare Zimbra's features with Microsoft Exchange Online Protection. Zimbra is open source, while Microsoft Exchange Online Protection is not. When I compare both the products, many free features are available in Zimbra because it is open-source software. It makes no sense to request Microsoft Exchange Online Protection add all the features people get on open-source software like Zimbra. Hence, I would say whatever features Microsoft Exchange Online Protection has are enough. Microsoft has a dedicated research team that should research and add new techniques like phishing and spamming solutions to the product.

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

"There are several features that I consider valuable."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"Since we have started using the solution, there have been fewer compromises."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"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."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"You can use the product to create special accounts."
"The product's most valuable feature is third-party integrations."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
"It is scalable."
"The pre-set policies and configuration analyzer are the most valuable features."
"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."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"Microsoft EOP's most valuable feature is a shared mailbox."
"The initial setup was relatively easy."
"One of the most valuable features is that it's very straightforward. It's a really simple interface. With our previous products, you could spend a week, if not more, training on those products just to figure out the interface. With SpamTitan it took an hour or two or three, tops."
"It is way more than just spam filtering. The reason I bought it was not just to control our spam, but to stop the evil guys from sending us phishing or all sorts of harmful emails. I can see the daily or weekly reports of how many of those types of things that it stops for me."
"The way we can customize filters is excellent. Other solutions tend to be restrictive with their specific profiles, but with SpamTitan, we can create them from scratch."
"It has reduced the risk of getting viruses from emails by almost a hundred percent. We are giving services to hundreds of companies, and it makes our work a lot easier when SpamTitan is filtering threats."
"We have a lot less spam going through. Because of this, work hours are not lost searching through all the spam emails to determine which ones are legitimate. This saves our bank clients' time since they are not forced to search their inbox for legitimate emails between spams. Not a lot of spam is going through. I think time is essential and we are gaining a lot of it with this solution since a lot of emails are automatically filtered out."
"The user interface for regular users is quite intuitive. The email report that they receive is pretty self-explanatory. The online interface for administrators is simple yet really quite effective. It's really a set-it-and-forget-it, and everything is available when needed."
"The solution keeps a copy of inbound and outbound messages for a period, which is a handy feature. It makes it easier to determine precisely what is happening with an email, where it came from, why it isn't routing correctly, why it is or isn't being flagged etc. If an end user forwards us a problematic email, the header information can be lost, making it harder to figure out what's happening."
 

Cons

"The GUI is sometimes slow to fetch the device report and could be improved."
"The product must provide better malware detection."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The XDR dashboard has room for improvement."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"I'd like some additional features any product can give me to protect our environment in a better way."
"We need to be able to whitelist data at the backend."
"The solution must improve the user experience."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"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."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"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."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"The GUI is problematic."
"Sometimes when I'm trying to pull up reports, the speed can suffer."
"The report comes out every morning. If a valid email gets blocked, I won't know about it until the next morning unless I log into the system to check, but it's quite a bit of work. Some users have requested that they get the report more often than once a day. If someone booked an airline flight or something that's time-sensitive and it gets blocked, they wouldn't find out until the next day. By then, it's probably too late. They would like notifications more often than once daily."
"The inter mailbox email flow needs improvement. If you are in the same domain, it does not have the capability to transfer one email to the same domain through SpamTitan. They need an API for Office 365 which is currently being developed"
"I would like to see a filter for searching inside the message content when it is quarantined."
"The product's GUI, dashboard, and speed could be better."
"When in the control panel, the context menu that appears when you right-click on an email should present options for adding the sender to the whitelist or blocking them."
"There should probably be a little more explanation on why one day, the email from one company goes into quarantine, and the next day, it doesn't. To me, it is a little bit random at times."
 

Pricing and Cost Advice

"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The pricing has become expensive."
"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."
"The product is very expensive."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The product's pricing is competitive for the US market."
"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 product is expensive."
"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."
"The solution should reduce the cost."
"It's a high price."
"It is a low-price solution."
"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."
"It's not extremely expensive. Other solutions get really pricey, really fast."
"Partner profitability is good with Titan HQ's partner program. This means that I recommend it to clients who trust me. My time and effort to educate them is compensated by TitanHQ, who provides the solution to me at a lower price than what the public gets it at, then I can make some money."
"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."
"We're happy with their licensing model. It was a major factor in why we chose them."
"The pricing model was one of the reasons that we selected it. The solution was very effective at what it did and it was very cost-effective. My client saved in the 30% to 40% range by installing it, so the pricing is competitive."
"The product's cost is average."
"Everything has really been great with the pricing and licensing. In fact, we just implemented ArcTitan because everything was going so well with SpamTitan."
