"Microsoft Sentinel provides the capability to integrate different log sources. On top of having several data connectors in place, you can also do integration with a threat intelligence platform to enhance and enrich the data that's available. You can collect as many logs and build all the use cases."
"Its inbuilt Kusto Query Language is a valuable feature. It provides the flexibility needed to leverage advanced data analytics rules and policies and enables us to easily navigate all our security events in a single view. It helps any user easily understand the data or any security lags in their data and applications."
"What is most useful, is that it has a good connection to the Microsoft ecosystem, and I think that's the key part."
"We are able to deploy within half an hour and we only require one person to complete the implementation."
"The best functionality that you can get from Azure Sentinel is the SOAR capability. So, you can estimate any type of activity, such as when an alert was triggered or an incident was found."
"I like the ability to run custom KQL queries. I don't know if that feature is specific to Sentinel. As far as I know, they are using technology built into Azure's Log Analytics app. Sentinel integrates with that, and we use this functionality heavily."
"The solution has features that helped improve the security posture of our clients. It provides the ability to correlate a large variety of log sources very cost-effectively, especially for Microsoft sources."
"The AI and ML of Azure Sentinel are valuable. We can use machine learning models at the tenant level and within Office 365 and Microsoft stack. We don't need to depend upon any other connectors. It automatically provisions the native Microsoft products."
"The most valuable features of ArcSight ESM are the dashboards, ease of management for anyone, and simple for teams to provide reports related to cyber security. There are a lot of good features that are provided."
"ArcSight ESM allows us to find if someone is doing an administrative operation at inappropriate times of day or trying to do something they're not allowed to."
"What I found most valuable in ArcSight Enterprise Security Manager (ESM) is its good integration with third-party products. The solution also has good core capabilities."
"The product is quite mature. It's been around for a long time."
"The correlation feature is good."
"Feature-rich solution which provides better network visibility for improved security"
"It is a robust product and has multiple valuable features."
"ArcSight is customizable. You can integrate just about anything. I also like the ease of use."
"Its dashboard is valuable. If you have a good knowledge of how to create a dashboard, you can create any dashboard related to cybersecurity. If fine-tuned, the alarms that are triggered for instant review are also very valuable and useful."
"The speed of the search engine"
"It is easy to use in any environment."
"The solution has proven to be quite stable."
"You can integrate Splunk with third-party security automation solutions and set rules for automatic response."
"If I need to integrate devices for logs, it is easier with Splunk. We can integrate different applications, network devices, and databases. It is also very rich in documents. It is the best."
"Speeds up root cause analysis and can help identify issues that your organization never realized were occurring."
"Splunk's advantage is its search capability. Its search is notably faster. With Splunk, I can search easily on keywords. That is great."
"The learning curve could be improved. I am still learning it. We were able to implement the basic features to get them up and running, but there are still so many things that I don't know about all its features. They have a lot of features that we have not been able to use or apply. If they could work on reducing the solution's learning curve, that would be good. While there is a training course held by Microsoft to learn more about this solution, there is a cost associated with it."
"The product can be improved by reducing the cost to use AI machine learning."
"They should just add more and more out-of-the-box connectors. It is quite a new product, and it has a lot of connectors, and even more would be good."
"There is room for improvement in entity behavior and the integration site."
"Sentinel should be improved with more connectors. At the moment, it only covers a few vendors. If I remember correctly, only 100 products are supported natively in Sentinel, although you can connect them with syslog. But Microsoft should increase the number of native connectors to get logs into Sentinel."
"When we pass KPIs to the governance department, there's no option to provide rights to the data or dashboard to colleagues. We can use Power BI for this, but it isn't easy or convenient. They should just come up with a way to provide limited role-based access to auditing personnel"
"We are invoiced according to the amount of data generated within each log."
"They should integrate it with many other software-as-a-service providers and make connectors available so that you don't have to do any sort of log normalization."
"The initial setup could be more straightforward."
"The security area has room for improvement."
"The visualization is not very good compared to Splunk."
"It is quite complex and could use a better UI. So the improvement would be a simplification. It is pretty complicated to use. The architecture is not complex but the setup and use are."
"There could be more API features for extracting logs on different devices included in the product."
"The customer experience could be improved."
"The stability isn't quite perfect. We occasionally run into problems."
"The API integration could be better, and I'd like to see more machine-learning capabilities in the future."
"I would like to see ability to master management. In terms of clustering, how it manages clustering needs improvement."
"Free-floating panels in the dashboards are like a glass table."
"The upgrading process could be smoother."
"The pricing can be better."
"It could be more user friendly, in terms of the end-user experience."
"It currently has limited default rules and customizations. If they can concentrate more on the compliance part and the security information part, it would be helpful. The platform part is good, but it requires many features from the security aspect."
"They can incorporate the SOAR solution within the actual product so that we do not require two different products, two different installations, and two different pricing methods. In regards to UBA, I am familiar with the UBA that existed two years ago. I am not updated about it today, but two years ago, UBA required such an amount of data that from a cost perspective, it was not worth it. When you compare it to what you get out of the box with Microsoft Sentinel without additional costs, there is no match."
"The historical data extraction needs improvement. I would like the capability of taking data and having it trend longer."
