"The most valuable feature is the onboarding of the workloads. You can see all that has been onboarded in your account on the dashboards."
"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."
"You can fine-tune the SOAR and you'll be charged only when your playbooks are triggered. That is the beauty of the solution because the SOAR is the costliest component in the market today... but with Sentinel it is upside-down: the SOAR is the lowest-hanging fruit. It's the least costly and it delivers more value to the customer."
"It has basic out-of-the-box integrations with multiple log sources."
"The log analysis is excellent; it can predict what can or will happen regarding use patterns and vulnerabilities."
"Sentinel has features that have helped improve our security poster. It helped us in going ahead and identifying the gaps via analysis and focusing on the key elements."
"Another area where it is helping us is in creating a single dashboard for our environment. We can collect all the logs into a log analytics workset and run queries on top of it. We get all the results in the dashboard. Even a layman can understand this stuff. The way Microsoft presents it is really incredible."
"Microsoft Sentinel comes preloaded with templates for teaching and analytics rules."
"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."
"Usability is the most valuable feature. The accessibility is quite good."
"It is a robust product and has multiple valuable features."
"The correlation feature is good."
"The stability of ArcSight Enterprise Security Manager is good."
"Once the rules are defined, it is capable of detecting minute changes in the systems, which are effectively based on the entries in the log."
"The tool is good for correlation and aggregation. We use it as a collection platform."
"There are many features that are good for clients who are looking for a good SIEM solution. They like the ease of creating a business that is effective and impressive."
"It is quite extensible. It is a platform that we can build our use instead of each case instead of each case being limited or restricted to each capability. This is probably the best feature."
"The best part of Splunk Enterprise Security is its customizable settings."
"Support is quick and competent."
"The data representation options in the dashboards are excellent."
"It's basically one of the best SIEM products on the market."
"The fact that Splunk is a platform and not just a SIEM solution is a key benefit."
"Splunk Enterprise Security comes with 300 pre-deployed use cases that can be easily customized to meet the specific needs of our organization, without the need to purchase additional tools."
"Alerts when a server is malfunctioning, monitors external attacks, and takes action to stop spreading viruses."
"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."
"The solution should allow for a streamlined CI/CD procedure."
"We'd like to see more connectors."
"I believe one of the challenges I encountered was the absence of live training sessions, even with the option to pay for them."
"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."
"I can't think of anything other than just getting the name out there. I think a lot of customers don't fully understand the full capabilities of Azure Sentinel yet. It is kind of like when they're first starting to use Azure, it might not be something they first think about. So, they should just kind of get to the point where it is more widely used."
"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 provides decent visibility, but it's sometimes a little cumbersome to get to the information I want because there is so much information. I would also like to see more seamless integration between Sentinel and third-party security products."
"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."
"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."
"The weakness in this system comes about because, with so many different logs, it is possible that the security analyst will lose information."
"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 customer experience could be improved."
"The first limitation is with the ArcSight Data Storage Manager (ADSM). ArcSight's total capacity is currently capped at 12 TB. This becomes an issue if a customer needs a longer real-time data retention period, such as exceeding 90 days or reaching a year or even ten months. Increasing the disk space beyond 12 TB is not currently possible."
"Its search part can be improved. When I go to the console and search for a few logs or something else, it takes a lot of time. When I try to search for three days or one week, it takes too much time. This is a major area of improvement. I wanted them to include features like SOAR, threat intelligence, and automation, and they seem to have included all these features in version 7.3 or 7.4."
"The centralized dashboard for the hybrid cloud environment needs to be more focused. It needs to be redefined because it's missing most of the information. It should be a little bit easy to use. Currently, integration with various applications and connectors is not that easy. Deployment is easy, but integration is not that easy. ArcSight also has a very high bandwidth consumption to pull the local servers. It should have some kind of better process or ability to transfer files from on-premises to the cloud, from the cloud to on-premises, and from a cloud to another cloud."
"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."
"The product was difficult to back up the first time."
"The complexity could be worked on so that it's even easier and faster."
"Integrating tools and creating use cases could be easier. It's hard for a junior security engineer with only a couple of years of experience to write use cases. They can do it, but it's much easier in a solution like IBM QRadar. Setting conditions is like a multiple-choice type of thing. It's a more user-friendly process."
"The GUI can be improved. Splunk has always suffered from having a kind of goofy UI, it needs some updating."
"If you monitor too much, you can lose performance on your systems."
"They should make data onboarding easier."
"The training was mostly sales-focused, like how to monitor your sales. It was hard to then come back from doing the training and try to switch it to a cybersecurity focus because all the training we did was sales oriented. The basic training didn't really touch on any kind of cybersecurity use cases or anything like that. That would have been great to see in the training."
