There needs to be an improvement in having the product work across multiple operating systems and have better support for non-Microsoft file types.

Defender for Office 365 handles the Microsoft supported file types, but MIP is limited. This solution does what it needs to do, but it does not go to the depth of if it was working with MIP, a holistic information protection system. It does not support all the file types an organization might use. For example, AutoCAD B1 for manufacturing or defence-oriented companies, they have to add a third-party add-on, or you would have to create the extensibility.

In an upcoming release, there should be business continuity features added. Proofpoint solution addresses what happens if you have an outage. If your tenant or your SaaS application is not available, there is no continuity right now with this solution. 

In one of the reports, I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help.

The custom alerts have to improve a lot. Though the system is very good, we have to go and check inside the admin panel to look at all kinds of reports. We won't get any mail alerts that highlight for us, for example, "today this many of spam attacks have happened". Or "these many emails have been blocked." We have to manually go into the admin panel and have to check it out. It would be nice if there are custom email notifications/alerts.

Right now, there are additional features such as mobile device management and data loss prevention, or eDiscovery (where the admin scans through the inboxes and see all your mail and notes any deviation) that are only currently available under the E5 license. You can't get these services as part of a base plan. In the future, it would be nice if they were added as part of the base plan as well.  

I was looking for some advanced features, like if I would receive an email that contains a legitimate file type, but the content is malicious, how I can protect against that? Normally, we are dealing with so many phishing and spam emails. I'd like some additional features any product can give me to protect our environment in a better way. 

There is always a chance to continue to improve the product in some way.

There is room for improvement with the UI.

The company should focus on adding threats that the solution is currently unable to detect. Sometimes it misses threats and viruses across the whole solution that are not covered under the current scanning. For example, if there are a hundred viruses that could be threatening us, sometimes Defender will only be able to scan for 95 out of 100.

We have to pay for storage for the solution. The storage cost should not be included in the subscription.

The notification rates are very high. It even notifies us for some small, low-priority viruses. My recommendation is that it should only notify us for high-level security threats that could highly affect our applications.

This is not really a defined product. You have to go to a lot of different places to enable things so it would be nice if you could go to one tab that says 365 Defender for Office 365 or something similar. You would be able to make all the settings and changes there, rather than having to go to lots of different places in the admin center to get it configured.

The visibility for the weaknesses in the system and unauthorized access can be improved.

Its price should be improved. Its cost is a major concern for us.

We are waiting for better software to block viruses. The feedback that we receive is that it is weaker when compared with other products such as Cisco and Palo Alto.

The only concern that we have is that this product is user-based, but we have requirements to run separate PCs or servers that are not on the same subscription. We need a separate license and we don't know how to get the license that is required.

We also wonder if it can prevent attacks from new types of viruses such as Widefire.

This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products. 

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.

I'd like to see fewer false positives and potentially have an accurate capability to detect malicious SharePoint sites. There could also be an improvement in some of the features related to training. In a phishing test campaign, for example, it should be more user-friendly and include the capability to evaluate and assess users' understanding of the content provided. 

In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement.

Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added.

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. 

We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email.
