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.

Enables us to create a user in the cloud and give them access to resources through a single workflow
The PAM for Active Directory is good. ActiveOps is quite useful as a feature. The One Identity active role enables us to create a user in the cloud and give them access to resources through a single workflow. We can create rules-based access. It helps us control audit management and IT access management. We can decide what people can access and detect job functions. It enables zero trust security with hybrid AD, find delegation, and role-based access control. It provides all certificates and provides secure authentication, call-based access control, et cetera. It's really important for my critical applications. We can see who's using what, whether they are authorized, and other information to decide what access to offer. With the active role console, I can find out the obvious issues and also perform a decent setup. The One Identity active roles enable us to reduce password reset times. We can handle tasks in a matter of a minute. It simplifies AD and Azure AD management, efficiency, and security overall. The password manager is very secure and is a self-service password manager solution. It is considerably decreasing my help desk tasks. Our engineering users can reset forgotten passwords, and it can implement a stronger password. The management around access to enterprise resources keeps my data and systems secure. We're easily saving at least one hour per day using this solution. The migration from AD to Azure AD is very easy. There are simple configurations, and the migration goes rather smoothly. We use the solution support for SaaS apps through Cloud Delivered SCIM connectors. There are controls that can be configured and we can add and set permissions easily.

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 of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"Microsoft Defender for Office 365 is a stable solution."
"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 product is not resource-intensive."
"The technical support is good and quick to resolve issues."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."
"Defender helps us prioritize threats across our organization."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"We're easily saving at least one hour per day using this solution."
 

Cons

"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."
"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."
"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."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"Microsoft Defender for Office 365 should be more proactive."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."
"We do have a Denial of Access happening."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
 

Pricing and Cost Advice

"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 product is very expensive."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"The product is expensive."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"The pricing has become 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."
