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.

Helps us stay compliant, has excellent malware detection, and is stable
The solution helped our organization stay 100 percent compliant with industry standards. MetaDefender Email Security can be set to be very aggressive for identifying attacks. This can be done based on how we want it. If we set it to this level, most of our emails will be blocked because the system will block anything that looks suspicious. We will also need to set the spam severity. This is the severity of everything, including phishing, spoofing, and other types of attacks. I would give the solution's ability to identify attacks a nine out of ten. MetaDefender helps us improve our spam catch rate. Any spam we receive is usually due to user subscriptions. We can specify rules of exclusion to meet our requirements as well. It also detects and blocks the links with suspicious codes. MetaDefender Email Security's multi-scanning capabilities for malware detection work based on how we set the parameters. The solution perfectly detects malware. MetaDefender can identify and disarm emails in zero-day attacks.

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 aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"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 for Office 365's most valuable feature is its performance."
"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."
"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."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Defender helps us prioritize threats across our organization."
"The biggest benefit is that we get fewer phishing and spam emails, so using IRONSCALES has made our environment much safer."
"It is a totally stable solution."
"The report function through Gmail is probably the most valuable feature. The next most valuable features are simulation and training."
"The stability is good."
"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 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 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."
"For what was being offered with IRONSCALES, I feel like we got an incredible deal."
"The sanitization is very good."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
 

Cons

"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."
"There's room for improvement regarding the time frame for retrieving emails."
"The XDR dashboard has room for improvement."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"I think the tool can continue to hone the product to ensure the detections are accurate."
"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."
"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."
"Even though they have been continuously improving it, it is not 100% there. We have had a few incidents where legitimate emails were getting blocked, and we had to manually remove those emails from quarantine. It is 90% effective or accurate because, on rare occasions, some emails from customers were not getting delivered. In one or two instances, their emails got blocked by IRONSCALES, and we had to manually remove the emails from quarantine. I would like them to improve their algorithm to avoid flagging genuine emails as malicious. I would also like to be able to whitelist certain email addresses. I'd love to be able to whitelist a particular customer."
"There's room for improvement in the campaign management. IRONSCALES has many built-in templates that I use, but you can also build templates from scratch. However, the interface for creating custom templates needs to be updated."
"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."
"The integration with Google Suite needs to be better. it's something they can work on."
"The DLP should be upgraded and has room for improvement."
"Although the number of AV engines is good, it could be better."
"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
 

Pricing and Cost Advice

"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The product is expensive."
"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."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"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."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The pricing has become expensive."
"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."
"The tool is not very cheap, but it is affordable."
"The product is available as a middle-priced tool. I think it is not the cheapest solution."
"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."
"They are pretty much the same as all the other competitors in the market."
"IRONSCALES is an expensive solution."
"As compared to everything else we looked at, it was good. It was the best value for the dollars."
"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."
"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."
"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
