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.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"I like that it's stable. It's been stable for a long time, and Microsoft Defender has done a good job there."
"The integration between all the Defender products is the most valuable feature."
"The timeline feature is excellent. I also like the phishing simulation. We have phishing campaigns to educate employees and warn them about these threats."
"The incident threat response and its ability to facilitate effective remediation against threats are the standout features."
"Vulnerability assessment and just-in-time access are some valuable features of Defender for server plans."
"Email protection is the most valuable feature of Microsoft Defender XDR."
"The attack simulation is excellent; initially, this feature wasn't very robust, but Microsoft improved what we could achieve with it. We can now customize our practice phishing emails and include our company logo, for example. Attack simulation also helps integrate with third-party solutions where applicable and provides an overview of our security architecture through testing. The summary includes areas for improvement in our protection and what steps we need to take to get there."
"The feature I find most valuable is Defender for Endpoint."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"Sometimes, digging into the information and knowing where to go can be difficult. It would be better if much of that information were immediately visible, especially when looking at endpoints or users."
"Microsoft tends to provide too many features, which makes the solution prone to bugs."
"The mobile app support for Android and iOS is difficult and needs improvement."
"Generally, antivirus products provide a central control to manage every device in terms of who is installing it or who is trying to disable it, but Microsoft doesn't have such a control center for the antivirus product it provides."
"Defender also lacks automated detection and response. You need to resolve issues manually. You can manage multiple Microsoft security products from a single portal, and all your security recommendations are in one place. It's easy to understand and manage. However, I wouldn't say Defender is a single pane of glass. You still need to switch between all of the available Microsoft tools. You can see all the alerts in one panel, but you can't automate remediation."
"It would be beneficial to reduce the number of clicks required to navigate between blades, as the current navigation and breadcrumb system can be a bit confusing."
"Offboarding latency should be reduced. Even after a device has been successfully offboarded using a particular offboarding script, it still shows up as onboarded."
"The user interface of Microsoft 365 Defender could improve. They could make it simpler."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"The license cost for a year is approximately forty-four thousand, and this annual saving is a significant factor in our decision to switch."
"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."
"For Defender, they have Endpoint Plan 1 and Endpoint Plan 2, but I don't know on what basis they have classified Endpoint Plan 1 and Plan 2, but it has given me enough pain to pick and design Endpoint Plan 1 or Endpoint Plan 2 for my organization. In fact, we are still struggling with it. Too many SKUs are confusing. There should not be too many SKUs, and they shouldn't charge for every new feature."
"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."
"The licensing fee for Microsoft 365 Defender is fair."
"I find the pricing to be quite competitive, especially considering its inclusion in our E5 subscription, which provides a comprehensive set of functionalities."
"The solution is affordable, and we haven't been hit with any hidden costs. The subscription model is straightforward, and it's easy to understand how much additional features cost. If we need to cancel a license or feature, we do that well in advance to avoid being charged for it, but overall, the pricing and licensing are simple and easy."
"It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size."
"It’s a single license platform."
