Gabor Nyerd - PeerSpot reviewer
Includes four services and four products, which can help organizations a lot
We found that sometimes integrations work, but testing them can take some time. Sometimes, configurations take much longer than expected. We have a configuration in place that needs to be synchronized with another server. However, the servers are four hours apart, so this can cause delays. In general, I believe that the time it takes to configure and test a service should be shorter. Sometimes, it can take a couple of hours to test a single configuration setting. Other times, it is only ten or fifteen minutes, which is normal. However, sometimes, even immediate actions can be triggered by configuration changes, and some settings can take up to eight hours to complete. I believe that this time can be improved. Microsoft is making a lot of improvements to its services in a short period of time. This is a good thing, as it means that the services are constantly being updated and improved. However, it can be challenging for customers to keep up with the changes. For example, a customer may read about an update, understand it, and share it with their colleagues and boss. However, it may take days or weeks to test the update and get the necessary approvals. This can be especially challenging for large customers with many users or machines. In some cases, Microsoft may change a service before the customer has had a chance to implement the previous update. This can be frustrating for customers, as it means that they have to constantly learn new things and adjust their workflows. On the one hand, it is important for Microsoft to keep updating and improving its services. This helps to ensure that the services are meeting the customers' needs and that they are staying ahead of the competition. Microsoft should also be mindful of the challenges that these changes can create for customers. One way to address this challenge is to provide customers with more time to implement changes. Microsoft could also provide more information about upcoming changes so that customers can plan ahead. Ultimately, Microsoft needs to strike a balance between keeping its services up-to-date and providing customers with a smooth transition to new features.
PR
Insightful detection and prevention of data loss mitigates legal risks and reduces potential lawsuits
Microsoft Purview Insider Risk Management was helpful in performing investigations after alerts were received. I was able to quickly identify the source of issues, which was valuable for data loss prevention. Additionally, it has saved us money on lawsuits and the loss of important confidential information that could lead to legal issues.

Quotes from Members

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

Pros

"The solution is well integrated with applications. It is easy to maintain and administer."
"Based on my experience, I rate Microsoft Defender XDR as nine out of ten."
"It provides a single pane of glass within the 365 admin interface, streamlining our experience by consolidating information in one place and eliminating the need to navigate through multiple interfaces."
"For technical support, I would definitely give a rating of nine out of ten."
"I like 365 Defender's advanced threat hunting. The dashboard is user-friendly with templates for site policies, etc. The most important use case is evaluating the risk links and applications."
"We can automate routine tasks and write scripts to carry out difficult tasks, which makes things easier for us."
"The advantage of Microsoft Defender XDR has over other XDRs in the market is that it's easy to use. You can quickly differentiate between alerts, incidents, devices, software, etc. It's easier to investigate an incident, and you have so many options. You can automate investigations and use playbooks. There's also the live response session, which is something you can't find in any other XDR."
"For me, the advanced hunting capabilities have been really great. It allowed querying the dataset with their own language, which is KQL or Kusto Query Language. That has allowed me to get much more insight into the events that have occurred. The whole power of 365 Defender is that you can get the whole story. It allows you to query an email-based activity and then correlate it with an endpoint-based activity."
"Insider Risk Management's graphing is highly specific and useful. You can see the last six months of data for the Microsoft tenant. You can easily find what you need. For example, you can filter for alerts about devices, emails, etc."
"Microsoft Purview Insider Risk Management was helpful in performing investigations after alerts were received."
"The best thing about Purview is that it's easy to integrate with our day-to-day environment. We have Active Directory, and Word and Excel. Using a third-party vendor and trying to integrate with our existing environment would be much more challenging."
 

Cons

"Improving scalability, especially for very large tenants, could be beneficial for Microsoft Defender XDR."
"The solution does not offer a unified response and standard data."
"A simple dashboard without having to use MS Sentinel would be a welcome improvement."
"The message trace feature for investigating mail flow issues should add more detailed information to the summary report... if they could extend the summary report a little bit, make it more descriptive, ordinary administrators could understand what happened and that the emails failed at this or that point. That way they would know the location to go to try to correct it and to prevent it from occurring again."
"The management and automation of the cloud apps have room for improvement."
"Microsoft support is not very good. You get stuck in low-level support for way longer than you should, instead of them escalating the issue up the chain."
"One of the biggest downsides of Microsoft products, in general, is that the menus are often difficult to find, as they tend to move from place to place between versions."
"The AI could be improved. As an analyst, I want to be able to interact more with AI. The AI simply sends summaries. I can't ask it, for example, if it has seen any suspicious activity with device two. I have to go and check device two for myself."
"The reporting capabilities sometimes leave a little to be desired. It could be improved in terms of producing reports to provide information to the C-suite or others."
"The user interface also isn't user-friendly. When we introduce Insider Risk Management to our clients, they often find it difficult to understand. There is too much information, and the UI is not scalable. Also, entry-level IT technicians are not always interested in learning something new. It should be clearer and easier to understand."
"For certain things, you need to install an agent. I understand it's for integrity, but if there could be a clientless solution for certain aspects, it would make life easier."
 

Pricing and Cost Advice

"Sometimes 365 Defender is expensive, but it can be moderate, depending on the organization's size and the license type. We're satisfied with the cost because it gives us a product that protects our entire environment with DLP. To compromise some cost, of course, we are to complete the most secure environment."
"Microsoft should provide lower-level licensing options. They should do it in such a way that even an individual could purchase a license, and it should be entirely flexible."
"The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper."
"Microsoft Defender XDR is priced high."
"The solutions price is fair for what they offer."
"There are no issues with pricing, but sometimes, the clarity in licensing is a concern."
"Microsoft Defender XDR is expensive."
"365 Defender is billed per account. I don't know the exact price, but my supervisor told me that Microsoft Defender is cheaper than the alternatives. It's bundled, so you get all the features in one place."
