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.

Quotes from Members

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

Pros

"It works well with medium to large-scale enterprises."

"This solution offers extensive customization options, making it possible to adapt it precisely to their requirements."

"It's easy to manage. There's a web interface and a command line, depending on what the user is comfortable with. There's a large knowledge base available, and the support is timely."

"The most valuable feature is the anomaly-reporting alarms."

"FortiSIEM sends an email or SMS notifications to admins when there are significant incidents. It's a highly efficient way of responding to incidents."

"Real-time monitoring makes life quite easy for me."

"AccelOps can handle a lot of data and it's just so important to true monitoring. Also, I can create a lot of rules to detect anything I like."

"We have found the most important features in Fortinet FortiSIEM to be the correlation, file utility check, latest file, and hash changes. These features are important for us."

More Fortinet FortiSIEM pros

"Microsoft 365 Defender's most valuable feature is the ability to control the shadow IP."

"Microsoft Defender's most critical component is its CASB solution. It has many built-in policies that can improve your organization's cloud security posture. It's effective regardless of where your users are, which is critical because most users are working from home. It's cloud-based, so nothing is on-premise."

"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 most valuable feature is the DLP because that's where we can have an added data protection layer and extend it not just to emails but to the documents that users are working on. We can make sure that sensitive data is tagged and flagged if unauthorized parties are using it."

"Microsoft Defender XDR has significantly improved our operational security."

"The incident-level visibility across the cyber attack chain when using Microsoft Defender XDR is great."

"Microsoft Defender XDR is a complete package of different Defender solutions, including Defender for Endpoint, Defender for Office 365, Defender for Cloud, and Sentinel SIEM, among others."

"Within advanced threat hunting, the tables that have already been defined by Microsoft are helpful. In the advanced threat hunting tab, there were different tables, and one of the tables was related to device info, device alert, and device events. That was very helpful. Another feature that I liked but didn't have access to was deep analysis."

Cons

"Our customers are noticing configuration available in the GUI interface and I think that they should be equal."

"The graphs on the user interface could be improved as we often experience glitches."

"Fortinet FortiSIEM needs to provide better API integrations to users."

"Fortinet FortiSIEM could improve to extend to several locations or sites."

"There is no proper guide for integration or configuration."

"The deployment of the platform took some time to set up and configure."

"The product does not have Security Orchestration and Automation Response, I would recommend adding this feature."

"Not very good on non-API features, lacks that functionality."

More Fortinet FortiSIEM cons

"The only problem I find is that the use cases are built-in. There is no template available that you can modify according to your organization's standards. What they give is very generic, the market standard, but that might not be applicable to every organization."

"A simple dashboard without having to use MS Sentinel would be a welcome improvement."

"The capability to not only thwart attacks but also to adapt to evolving threats is crucial."

"Advanced attacks could use an improvement."

"For Microsoft Defender XDR, there is currently no ability to reset passwords for on-premises accounts, which is a key challenge."

"Just like in any solution, the price can always be cheaper."

"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. Some inconsistencies exist between blades, which could be improved for a more seamless user and UI experience."

"The solution can improve the rules and privileges it offers."

Pricing and Cost Advice

"This is probably more on the lower cost end of the spectrum compared to competing products. Fortinet's license model is based on events per second, which makes sense, but that's not typical. It makes it very hard to calculate what your costs are going to be as you scale the platform because some log sources, such as firewall logs, are very noisy, and there are lots and lots of events per second, but some of them are not. So, it becomes a bit of a science experiment trying to guess what your costs are going to be as you scale the solution. This is where other competing products perhaps have a more straightforward license model."

"They have a yearly subscription."

"The price of the solution is expensive. The license is scalable. If there are 10 devices it is simple to license."

"Pricing is acceptable for more than 90% of our customers, as they normally get discounts."

"FortiSIEM's licensing is based on EPS, and its pricing is competitive in the market."

"Manageable, however would be better as pay as you go versus CapEX."

"Pricing is determined based on the customer's budget."

"There is a need to make yearly payments towards the licensing charges attached to the product. The free version license of the product is available for two months."

More Fortinet FortiSIEM pricing and cost advice

"The pricing of Microsoft 365 Defender is definitely on the costly side, but with the features and services that Microsoft provides, such as the seamless integration of all the Defender tools, while the price is on the higher side, there is no alternative."

"Purchasing Microsoft Defender XDR as part of a Microsoft 365 bundle can be cost-effective, but acquiring it as a standalone product may be more expensive."

"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."

"The solution is too expensive."

"It is fairly priced because we get complete integrated services with the E5 license."

"Microsoft 365 Defender offers competitive pricing."

"With the little idea I have about the costs, I can say that XDR tools tend to be a bit expensive. If you are using Microsoft Defender XDR, then you need to go for a subscription-based pricing model."

"There are no issues with pricing, but sometimes, the clarity in licensing is a concern."
