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.

Facilitates creation of your own content-filtering policies with relative ease
* Ability to create message bypasses for groups and/or individuals. Meaning, you do not have to "whitelist" email domains or addresses when a specific bypass will do. * Personal Message Manager (PMM): It allows users to release or delete quarantined messages. Also, allows users to add people to a Trusted Senders list. * Ability to create your own content-filtering policies with relative ease.

Ensures that there is maximum security enabled for our communication processes
There has been issues when I have interacted with the support in the past, especially regarding technical issues. I have found them responsive for basic queries, but when I have raised issues for complex issues, there is a delay in the response from the support team. During the initial setup, when I faced challenges, the support team took a lot of time to address the issue and escalate it to the required personnel. In another issue raised, I was trying to confirm the status of a domain name. The support team was not able to help me out and provide with the necessary information. I suggest that there should be improvement in the support team towards handling such complex issues and technical concerns.

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 its spam filter."
"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."
"The product is not resource-intensive."
"There are several features that I consider valuable."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"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."
"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."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"The tool is a good solution for protecting against email attacks and monitoring networks. It supports our compliance efforts and is easy to use and stable."
"I have found Sophos Email to be scalable."
"Sophos Email provides both inbound and outbound filtering."
"The anti-malware, risk scanning has been pretty spot on."
"Sophos Email is a stable solution."
"The tool's most valuable feature is the anti-spam detection filter. Its threat email intelligence features help to identify email data."
"The filtering capabilities are precious and far superior to others I've used. It's intuitive in what it pushes to quarantine, and users can quickly review, free, or delete items without needing an administrator, making it ideal for a multi-user environment."
"The anti-spam functionality of Sophos Email is good."
 

Cons

"Several simulation options are available within 365, and the phishing simulation could be better."
"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."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"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."
"You should be able to deploy Defender for every subscription without the need to add servers."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"FTP server and TRUST Manager functionality."
"Malware needs improvement."
"Servicing and support are areas with shortcomings where the solution needs to improve."
"Enhancing rule creation and customization features would provide users with greater control over their email security settings."
"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."
"The product could include all the essential features and capabilities, similar to the on-premise, server-based version."
"The tool’s stability should be improved."
"Email installation could be more user-friendly so that it can be done without involving the partner"
"Sophos Email could better detect fake emails, especially when the domain names are similar. It needs to improve spotting spoofed domains, like when one letter differs in a domain name. It also needs to incorporate AI detection. Barracuda detects suspicious emails better. However, malware scanning is better in Sophos Email."
"I would like to see improvements in the initial setup process, ensuring better compatibility with diverse customer infrastructures."
 

Pricing and Cost Advice

"The product is very expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"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."
"It's a user-base subscription."
"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 expensive."
"I was working in the government and it was too expensive for us to use our Microsoft products."

"Sophos Email is priced lower than its competitors."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."

"The product is cheaper compared to other solutions."
