"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."
"We’ve got process improvement that's happened across multiple different fronts within the organization, within our IT organization based on this tool being in place."
"The dashboard that allows me to view all the incidents is the most valuable feature."
"The most valuable feature is the onboarding of the workloads. You can see all that has been onboarded in your account on the dashboards."
"The main benefit is the ease of integration."
"The UI of Sentinel is very good and easy to use, even for beginners."
"Azure Application Gateway makes things a lot easier. You can create dashboards, alert rules, hunting and custom queries, and functions with it."
"In Azure Sentinel, we have found, they do have a store in their capability. AI and intelligence features. We found that to be very helpful for us because some other things we do need to integrate again or find another vendor for the store"
"The out-of-the-box rules that help us configure functioning rules within the environment are valuable."
"Customization. ArcSight gives you a platform to on-board out-of-the-box devices with a more accurate way of collecting desired logs/events."
"It is a robust product and has multiple valuable features."
"It makes maintenance very easy."
"The most useful features are directories, price, and live reporting."
"The stability of ArcSight Enterprise Security Manager is good."
"The product is quite mature. It's been around for a long time."
"This process has helped to improve our organization because we have centralized the intra-group security equipment logs."
"Splunk has a wide range of features that customers use to find and analyze all kinds of logs."
"The ability to ingest any data and display it in a way that anyone can understand."
"The product is adept at log mining."
"It is very stable. We have not had any problems."
"It has the ability to correlate data, analyze and review it."
"Splunk has significantly helped with aggregation and correlation of critical logs. Not having to grep on each individual server has made everyone more efficient."
"We have found all the features useful. However, the dashboarding and logging have been very helpful. Additionally, the log analysis does a great job."
"It helps us uncover bottlenecks in the network."
"At the network level, there is a limitation in integrating some of the switches or routers with Microsoft Sentinel. Currently, SPAN traffic monitoring is not available in Microsoft Sentinel. I have heard that it is available in Defender for Identity, which is a different product. It would be good if LAN traffic monitoring or SPAN traffic monitoring is available in Microsoft Sentinel. It would add a lot of value. It is available in some of the competitor products in the market."
"Its documentation is not so simple. It is easy for somebody who is Microsoft certified or more closely attached to Microsoft solutions. It is not easy for those who are working on open-source platforms. There isn't a central point where everything is documented, and there is no specific training or certification."
"In terms of features I would like to see in future releases, I'm interested in a few more use cases around automation. I do believe a lot of automation is available, and more is in progress, but that would be my area of interest."
"The performance could be improved. If I create 15 to 20 lines for a single-use case in KQL, sometimes it takes more time to execute. If I create use cases within a certain timeline, the result will show in .01 seconds. A complex query takes more time to get results."
"The following would be a challenge for any product in the market, but we have some in-house apps in our environment... our apps were built with different parameters and the APIs for them are not present in Sentinel. We are working with Microsoft to build those custom APIs that we require. That is currently in progress."
"The AI capabilities must be improved."
"The dashboards can be improved. Creating dashboards is very easy, but the visualizations are not as good as Microsoft Power BI. People who are using Microsoft Power BI do not like Sentinel's dashboards."
"The solution should allow for a streamlined CI/CD procedure."
"The analytics feature is not reliable and needs improvement for more detailed analysis."
"Sometimes, it takes ages to get an issue resolved. I have ArcSight experience, so I normally try to fix things on my own or find a workaround, but it's tough to get support when I need it."
"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."
"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."
"The customer experience could be improved."
"The user interface of ArcSight Enterprise Security Manager could improve. It is not very good. Additionally, they could integrate the web interface better."
"When we need to consume old events, we have to wait for a long time. ArcSight should improve the database capability to reply to queries faster. It would also be interesting if they implemented network visibility. For example, they could add a feature like NetWitness with a model just for looking through the packets."
"The way that scaling is set up isn't very cost-effective."
"The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."
"We find that the maintenance process could be a lot better."
"I would like to get visibility into the data pipelines on heavy forwarders and indexers to see exactly their source and the cause of saturation when it occurs. This would help us learn even more about our high use applications."
"The user access control could be much more granular, so that the admins can control r/w/x access for specific features of the product like dashboards, etc."
"We were inundated with the amount of alerts and alarms that we could get out of it. It is also a resource hog and we didn't have the resources to support it on-prem so we're taking it offline now."
"When you get into large amounts of data, Splunk can get pretty slow. This is the same on-premise or AWS, it doesn't matter. The way that they handle large data sets could be improved."
"In terms of the interface, it could include some improvements for the look and feel."
"Delays in responses from the technical team can pose challenges for both vendors and clients, especially considering that Splunk applications and machine solutions are critical assets."
