"Sentinel's most important feature is the ability to centralize all the logs in one place. There's no need to search multiple systems for information."
"Native integration with Microsoft security products or other Microsoft software is also crucial. For example, we can integrate Sentinel with Office 365 with one click. Other integrations aren't as easy. Sometimes, we have to do it manually."
"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."
"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."
"Microsoft Sentinel enables you to ingest data from the entire ecosystem and that connection of data helps you to monitor critical resources and to know what's happening in the environment."
"The UI of Sentinel is very good and easy to use, even for beginners."
"The Log analytics are useful."
"Log aggregation and data connectors are the most valuable features."
"The webpage algorithm is the most valuable feature because it was the fastest feature for searching the logs, events, and correlation."
"Some of the benefits of using this solution are rapid correlation and near-time response on alerts."
"ArcSight ESM provides us the flexibility to write our own passwords and customize the solution. It lets us search and log a variety of SmartConnectors. It has 480-plus SmartConnectors."
"I think that the overall experience with this solution is good, but in particular, I think that the dashboards are quite interactive."
"We use ArcSight ESM for log analysis and security alerts. It warns us of threats and then helps us conduct a forensic investigation of a cyber attack or internal incident after it happens."
"Usability is the most valuable feature. The accessibility is quite good."
"The solution offers very good monitoring."
"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 level of robustness on offer is very good."
"The flexibility of the search capability is most valuable. You can use it for more than just a basic log aggregator. It is powerful in that regard."
"The most valuable feature of Splunk is the log monitoring."
"The ability to ingest different log types from many different products in our environment is most valuable."
"The ability to rapidly diagnose problems in production and non-production, across hundreds of log files, is the most valuable feature."
"The correlation searches are most valuable just because we are able to do things like RBA."
"The varied prebuilt feature is the most valuable because it ensures that we have complete coverage over all of the key questions."
"What I really like is that even if you have already collected the data, you can extract fields and can build searches."
"They're giving us the queries so we can plug them right into Sentinel. They need to have a streamlined process for updating them in the tool and knowing when things are updated and knowing when there are new detections available from Microsoft."
"We've seen delays in getting the logs from third-party solutions and sometimes Microsoft products as well. It would be helpful if Microsoft created a list of the delays. That would make things more transparent for customers."
"The reporting could be more structured."
"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."
"Documentation is the main thing that could be improved. In terms of product usage, the documentation is pretty good, but I'd like a lot more documentation on Kusto Query Language."
"I would like Sentinel to have more out-of-the-box analytics rules. There are already more than 400 rules, but they could add more industry-specific ones. For example, you could have sets of out-of-the-box rules for banking, financial sector, insurance, automotive, etc., so it's easier for people to use it out of the box. Structuring the rules according to industry might help us."
"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 AI capabilities must be improved."
"ArcSight ESM could improve by adding more features and documentation. There needs to be more documentation."
"The roadmap is not clear."
"The customer experience could be improved."
"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."
"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."
"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."
"In certain cases, this product does have false positives, which the company should work on."
"We have pricing issues. ArcSight ESM may not be the most user-friendly option, and its interface is quite traditional. However, despite these aspects, we find it a good cybersecurity solution. It needs to improve the dashboards, documentation, and support as well."
"Splunk could enhance its services by providing more comprehensive professional assistance aimed at optimizing our investment."
"They should make data onboarding easier."
"Make it easier to include roles and user controls, as it is horrible now."
"There are a lot of competitive products that are doing better than what Splunk is doing on the analytics side."
"Splunk does not build apps. They only go back and validate the apps that somebody has already built. They should have remote consulting support. They have a wonderful solution. They have 24/7 security. Nobody needs to depend on any third party and will therefore just buy Splunk on the cloud."
"This is not really a monitoring solution."
"I think the tech support response time could be a bit better. Sometimes I need to wait more than 24 hours for a response to my tickets."
"Previously, they developed custom connectors or add-ons for a lot of applications. But that number can be upgraded still. There are a lot of applications in the world that are not supported."
