Tolu Omolaja - PeerSpot reviewer
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.
Orion Trist - PeerSpot reviewer
Saved us a big deal by catching malicious links and attachments sent directly to our staff and has also been helpful for educating our staff
It has helped immensely because it has gotten rid of malicious links and malicious attachments that have been targeted at our different staff members. It has definitely protected us on more than one occasion. Their integrated approach of combining email security and employee awareness training is excellent because the training is a reminder for staff to continually be on their feet and look out for the ever-changing landscape. It also lets us know who has been trained, who hasn't been trained, and what they're like. It integrates a risk ratio for all our employees. Its artificial intelligence and machine learning capabilities are very important because I don't want to have to manage 24/7. Having the AI to do a lot of the work for me is invaluable. Its automated detection and response capabilities are excellent. It does a wonderful job. They provide all the stats on what it has done. It gives you information about how much time is saved and all that kind of good information. Its automated detection and response capabilities have massively decreased the time we spend manually reviewing email events. Since May, it has taken care of 170 hours. So, it has saved 88 hours per analyst. It is very good in terms of the customization of the automated detection and response capabilities. It is granular, and you can adjust it however you want. If it is too high, you can turn it down. If it is too low, you can turn it up.

Easy to setup, stable and highly scalable
The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through. In future releases, I would just like to see that ability for users to see what's being quarantined and what's not quarantined but safe. Just those genuine false positives.

Quotes from Members

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

Pros

"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."
"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."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"The product is not resource-intensive."
"The basic features are okay and I'm satisfied with the Defender."
"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 initial setup was easy."
"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 report function through Gmail is probably the most valuable feature. The next most valuable features are simulation and training."
"It is a totally stable solution."
"For me, the mobile app is most valuable. All other features are also very useful, but the mobile app makes it really easy for me to manage on the go. I don't have to be at my desk. I could be at the shops, or it could be in the evening when I am out, and I can get a notification on my phone that there is an incident that has been raised. I can sort it out very quickly without having to be at my work PC."
"The stability is good."
"The most valuable features of the solution are that it is easy to set it up, install, and manage the product."
"I would say the most valuable feature is what they call Themis. It's like a virtual analyst that uses the decisions that system admins make to generate a score for whether an email is legitimate, spam, or phishing. It gets better based on the decisions that we make over time. The automation piece is great as well. The integrated approach of email security combined with employee awareness training is excellent."
"AI-driven phishing detection and incident remediation are valuable. It saves time from having to do manual analysis and investigation, and we also get alerts for phishing emails."
"The solution captures a bit more of the unknown, quantifies it, and applies intelligence to it to pick out and stop a lot of phishing emails that come through."
"I like its ability to detect and block."
 

Cons

"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"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."
"Microsoft Defender for Office 365 should be more proactive."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"The phishing and spam filters could use some improvement."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"The simulation and training piece could be improved by having more granularity in terms of scheduling how campaigns are run and allowing people to directly take the training rather than having to go through an official campaign. That's not available yet."
"IRONSCALES should bundle more features together instead of separating them and charging additional licensing fees."
"I would love to see the indication of compromise and how the solution utilizes open source resources. It would be good to see that included in the paid versions. It would be a small addition but add a lot of value for clients."
"I would like it if IRONSCALES had some sort of reminder mechanism, meaning IRONSCALES knows if a user completed the training or not. As long as it hasn't been completed, it keeps reminding every so often, alerts the manager, etc. Right now, it is all in the hands of the employee, and not all of them continue the process, which is a shame."
"In addition to integrated training, they should also have personalized training that you don't have to do as part of a phishing campaign or a simulation."
"Its UI could be improved. My pet peeve with a lot of these cloud-based systems is that a lot of times, the interface for the management is a little clunky. If you live and breathe IRONSCALES all day long, you'll obviously know where everything is just from muscle memory, but the system is not designed for people to be in it all day long. You're only supposed to occasionally look at it. When things get moved around, it is not necessarily that intuitive. I'm an IT guy, and I can pretty much take the worst UI and figure it out, but the menus and the options in the interface could be a little cleaner graphically. If you have a quick problem that you want to resolve, it takes a little bit of digging in the admin console, whereas it should take a few clicks up front."
"The tool supports 15 to 16 languages, but the content it uses in the training in Spanish has certain limitations."
"The only thing that I could say is that some of the reporting features could be better."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is very expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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."
"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."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"I don't know about its pricing because I don't run the budget or pay the bills, but if it was extortionate, we probably would be looking to scrap it, and because we are not, I assume its price is okay."
"We pay $3000 plus a little more a year for the number of employees we have, and we're not even that big. The solution is at the higher end in terms of cost. It's not the most expensive product, but I would say it's worth the price if you have a high volume of email traffic. In our case, the solution has inspected over 162,000 emails between three and four months. It saved us a lot of time and money. It's a worthwhile investment because a bad actor only has to succeed once; we must defend against everything in our business. IRONSCALES offers a sense of security and confidence from being well protected."
"The tool is not very cheap, but it is affordable."
"Considering the value it provides, it is definitely worth the cost. We don't have to do manual analysis and remediation of phishing emails, which saves us a lot of hours. Its licensing is based on the number of users being supported and the number of email addresses being protected. I'm not aware of any additional costs."
"They are pretty much the same as all the other competitors in the market."
"There is an installation cost. Since we have this as a managed service, we pay for licensing and the managed service itself. Other than that, there are no additional costs."
"IRONSCALES is an expensive solution."
"As compared to everything else we looked at, it was good. It was the best value for the dollars."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
