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.

Solution integrates well with existing systems while being easy to use
The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use. Furthermore, Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company. The solution is easy to reuse and not difficult to find expertise for in the market because it is widespread. It is gaining attention even from partners and from the market on the offering side. This serves as a good starting point for customers who can develop internal competence on the solution. Additionally, the presence of reliable partners who know the solution and can provide internal knowledge is the best aspect for them.

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 feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"The product is not resource-intensive."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"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."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"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 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 for me is the firewall capabilities."
"I have not encountered any stability issues with Microsoft Entra External ID."
"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."
"The most beneficial feature for us is the ease of setup. With about five clicks, we can generate unique IDs and keys and set up in less than 30 minutes. We can also generate these for multiple years simultaneously, which is convenient."
"It's quite easy to manage and monitor."
"Microsoft Entra External ID is more secure, offering a secure environment."
"It's similar to using a Microsoft account to create accounts on other websites. We are also using Microsoft Entra to monitor which applications our guests are using. This allows us to filter, block, or adjust permissions for these applications as needed for our collaborators."
"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."
 

Cons

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"We need to be able to whitelist data at the backend."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"The custom alerts have to improve a lot."
"There's room for improvement regarding the time frame for retrieving emails."
"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."
"Several simulation options are available within 365, and the phishing simulation could be better."
"The problem with Microsoft products is that they often cater to enterprise-level needs, which can be too costly for medium-sized businesses."
"Technical support needs improvement."
"The quality of Microsoft customer support varies. With an enterprise contract, good resources are usually provided, especially in regions like Saudi Arabia or UAE. However, we have faced challenges with support quality, especially in some subcontinent areas where the resources might not be as experienced."
"I generally find Microsoft solutions expensive, especially in specific offerings."
"A common concern among the customers I visit is the unpredictability of Microsoft's costs at every renewal. This is really bothersome for the customer, and I would say it is the worst element I have seen in these years."
"The cost is very high."
"Single sign-on for external applications such as Oracle could be improved to be a little bit cheaper."
"Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options."
 

Pricing and Cost Advice

"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"I was working in the government and it was too expensive for us to use our Microsoft products."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The product is very expensive."
"The product is expensive."
"The pricing has become expensive."
"We don't pay separately for Microsoft Entra External ID as it's part of our Microsoft Exchange subscription."
