"The UI-based analytics are excellent."
"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 most valuable feature is the performance because unlike legacy SIEMs that were on-premises, it does not require as much maintenance."
"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."
"Previously, it was a little bit difficult to find where an incident came from, including which IP address and which country. So in Sentinel, it's very easy to find where the incident came from since we can easily get the information from the dashboard, after which we take action quickly."
"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."
"We are able to deploy within half an hour and we only require one person to complete the implementation."
"The connectivity and analytics are great."
"It makes maintenance very easy."
"The most valuable feature of ArcSight ESM is its ease of use."
"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."
"We have been satisfied with the support."
"It is a vital tool for live monitoring and helps us to understand the traffic alerts of any major issue on the network, thereby reducing hacking attempts."
"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."
"The user interfaces are quite good and speedy."
"The filters and the ability to do what you want are the most valuable features. There is nothing that you cannot do in this solution. It has all the features, which makes it very dynamic."
"I am satisfied with the support."
"Splunk has facilitated the correlation of information security logs to look for incidents which could cause damage to the company's infrastructure, as well as financial losses from leaks."
"The solution has proven to be quite stable."
"Its integration is most valuable. Its UI is also pretty much easy."
"I like the ease with which dashboards can be created."
"The correlation searches are most valuable just because we are able to do things like RBA."
"The level of robustness on offer is very good."
"The stock analysts and security people use one single dashboard (one single location) to check our logs."
"Currently, the watchlist feature is being utilized, and although there have been improvements, it is still not fully optimized."
"Microsoft should improve Sentinel, considering that from the legacy systems, it cannot collect logs."
"I think the number one area of improvement for Sentinel would be the cost."
"If I can use Sentinel offline at home and use it on a local network, it would be great. I'm not sure if I can use Sentinel offline versus the tools I have."
"While I appreciate the UI itself and the vast amount of information available on the platform, I'm finding the overall user experience to be frustrating due to frequent disconnections and the requirement to repeatedly re-authenticate."
"Its implementation could be simpler. It is not really simple or straightforward. It is in the middle. Sometimes, connectors are a little bit complex."
"Azure Sentinel will be directly competing with tools such as Splunk or Qradar. These are very established kinds of a product that have been around for the last seven, eight years or more."
"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."
"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."
"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."
"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."
"They need to develop NetFlow appliances that can be installed in the customer network on span ports, collect NetFlow, and send it to ArcSight without relying on the devices' NetFlow capability and their position in the network."
"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."
"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."
"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."
"The dashboard looks a bit cumbersome."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"The configuration could be better."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
"The product's price may be an area of concern where improvements are required."
"Splunk Enterprise Security should provide a better and richer integration."
"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."
"There is a definite learning curve to starting out."
"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."
