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.

Provides comprehensive email security management, effective in detecting a wide range of email threats
The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails. This means Abnormal Security would assess emails before they reach my inbox, even if it happens slightly after Microsoft's initial scan. Currently, the process isn't seamless. Microsoft analyzes emails and delivers legitimate ones to my inbox. Abnormal Security then scans these delivered emails, and if flagged as malicious, they disappear. This creates a problem for our ticketing system mailbox, which is a third-party service. Emails sent to the ticketing system address are automatically forwarded by Microsoft. However, if these emails are malicious, Abnormal Security only cleans them from my Outlook mailbox after they've been forwarded. Since we primarily rely on the ticketing system and not the Outlook mailbox, these malicious emails still reach the ticketing system.

Lags in terms of grabbing phishing emails or phishing campaigns, though it has good scalability
Armorblox is a cloud-based solution. The solution helped us improve the security, but we had a couple of issues regarding the operation. From an email security perspective, users or employees don't need gray mail or phishing emails in their email boxes. So, if the tool is not performing well in that area, then there's no sense in using that particular tool. Overall, I rate Armorblox a five out of ten.

Quotes from Members

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

Pros

"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"Scalability-wise, I do not think there are any issues so far."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"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 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."
"Does a thorough job of examining email and URLs for malicious content."
"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."
"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"I would recommend Abnormal Security."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"Armorblox is a scalable solution."
 

Cons

"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"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."
"We need a separate license and we don't know how to get the license that is required."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"There's room for improvement regarding the time frame for retrieving emails."
"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 pricing for academic institutions and student mailboxes is challenging."
"Abnormal should add more automatic reports. I have an open request to our account team for more notification and report types that can be sent automatically. For example, they have an awesome report that gets sent weekly, and I also want them monthly, so I don't need to do so much adding up when my director wants numbers over time."
"There could be more selectable options and more granular selections available."
"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"One feature I'd love to see is outbound scanning."
"The biggest pain point for us is the lack of support for on-premise email systems."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"Armorblox lagged in terms of grabbing phishing emails or phishing campaigns."
 

Pricing and Cost Advice

"The product is 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."
"I know that the product is incredibly expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing has become expensive."
"The license is expensive because the cost is based on the number of users."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"The license is based on the user count, so the number of users that have an email address in the organization."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
