"The data connectors that Microsoft Sentinel provides are easy to integrate when we work with a Microsoft agent."
"We can use Sentinel's playbook to block threats. It covers all of the environment, giving us great visibility."
"There are some very powerful features to Sentinel, such as the integration of various connectors. We have a lot of departments that use both IaaS and SaaS services, including M365 as well as Azure services. The ability to leverage connectors into these environments allows for large-scale data injection."
"It's easy to use. It's a very good product. It can easily ingest data from anywhere. It has an easily understandable language to perform actions."
"The analytic rule is the most valuable feature."
"The UI-based analytics are excellent."
"The Identity Behavior tab furnishes us with the entire history linked to each IP or domain that has either accessed or attempted to access our system."
"The most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."
"The correlation feature is good."
"ArcSight is customizable. You can integrate just about anything. I also like the ease of use."
"It has absolutely improved the efficiency of our security team. We use it internally as well. It is such a powerful tool that our internal security team became a customer of our ArcSight managed service."
"Once the rules are defined, it becomes easy to detect changes and generate automated logs."
"Stable solution with good customer service support."
"The most useful features are directories, price, and live reporting."
"The reports that we are from getting from ArcSight are very valuable. The reporting in ArcSight is good. Our regulators ask us for the reports on a regular basis, and we have been able to provide the required data. Its overall functionality in terms of log analysis and the speed at which it does that is also valuable. It is very quick. Whatever alerts we had configured were extremely fast. We immediately get alerts when there is unauthorized access or unknown access, or even positive access. This is where we found the difference between ArcSight and other solutions."
"The tool is good for correlation and aggregation. We use it as a collection platform."
"We were able to create a catalog of dashboards and have a holistic view at all levels. We could understand our business much better. Real-time errors, which were buried in emails before now, surfaced up on dashboards."
"The SIEM is the most valuable feature of the product."
"Splunk helps us be more proactive. We can take predictive action to identify and block threats so that nothing harmful gets into the system."
"Our clients are easily able to modify and evolve their implementations."
"We can automatically suspend or terminate suspicious sessions."
"We solve issues that we previously could not since we now have the data."
"It provides logs in one place, so they are easy to find. It collects the logs from multiple places, then you have just one place where you see the whole flow from the front-end to the back-end."
"It provides a risk score for each object, device, or user. We can then take action if they are at a higher risk."
"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"
"I think the number one area of improvement for Sentinel would be the cost."
"We have been working with multiple customers, and every time we onboard a customer, we are missing an essential feature that surprisingly doesn't exist in Sentinel. We searched the forums and knowledge bases but couldn't find a solution. When you onboard new customers, you need to enable the data connectors. That part is easy, but you must create rules from scratch for every associated connector. You click "next," "next," "next," and it requires five clicks for each analytical rule. Imagine we have a customer with 150 rules."
"We'd like to see more connectors."
"Sentinel's alerts and notifications are not fully optimized for mobile devices. The overall reporting and the analytics processes for the end user should also be improved. Also, the compatibility and availability of data sources and reports are not always perfect."
"The KQL query does not function effectively with Windows 11 machines, and in the majority of machine-based investigations, KQL queries are essential for organizing the data during investigations."
"The reporting could be more structured."
"The only thing is sometimes you can have a false positive."
"Deployment typology could be improved. Difficult to scale across all the different lines of businesses."
"The initial setup could be more straightforward."
"What could be improved in ArcSight Enterprise Security Manager (ESM) is its analytics feature. That feature should be more powerful and have more correlation in terms of AI/ML, though MicroFocus has done a good job in adding analytics to ArcSight Enterprise Security Manager (ESM) which has become a big draw to customers. What I'd like to see in the next release of the solution is the addition of AI/ML features."
"Could benefit from a more modern interface."
"The stability isn't quite perfect. We occasionally run into problems."
"I am having issues with report generation with older versions. I don't know if this is because of compatibility issues, but report generation has been a little bit difficult in older versions. It is not similar to the newer and current versions. We are looking at moving to the cloud. It would be good if ArcSight ESM can move to the cloud. They already seem to be working on this. It would also be very helpful and great if we can integrate external threat intelligence, machine learning, and AI into this solution. It has good dashboards, but they can always be better. Its stability can also be improved."
"They also could improve the product by integrating user and identity behavior analytics."
"In other products, I have found that they use some kind of GUI that is drag and drop. While in ArcSight they use still scripting. They should keep scripting because some people prefer scripting but they should have the option for those who prefer using drag and drop."
"The setup time is quite long."
"In the next releases, I would like to see more pricing flexibility."
"The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
"The presence of multiple layers creates a significant challenge for monitoring across cloud environments."
"My company could benefit from doing more Splunk training with Splunk consultants teaching us how to use it."
"The upgrading process could be smoother."
"The implementation and the scanning of the logs can be difficult."
"When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time."
