"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."
"Sentinel uses Azure Logic Apps for automation, which is really powerful. This allows us to easily automate responses to incidents."
"Microsoft Sentinel provides the capability to integrate different log sources. On top of having several data connectors in place, you can also do integration with a threat intelligence platform to enhance and enrich the data that's available. You can collect as many logs and build all the use cases."
"Sentinel improved how we investigate incidents. We can create watchlists and update them to align with the latest threat intelligence. The information Microsoft provides enables us to understand thoroughly and improve as we go along. It allows us to provide monthly reports to our clients on their security posture."
"We have no complaints about the features or functionality."
"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."
"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."
"The primary valuable feature is that it has replaced a whole lot of other products with one platform."
"The ability to write my own parsers for the devices that are not supported by Fortinet is the most valuable feature."
"Fortinet FortiSIEM provides good detection against advanced threats."
"There are things like dashboards and reports (pre-configured and custom) that let me know that things are operating the way they should be, and when they are not."
"It's very easy for anyone to work with."
"The solution is very stable. It's run for years without the need to do anything except, add new patches when they are available, which are always a good idea to install."
"Fortinet FortiSIEM's most valuable feature is the simplicity in handling multi-tenancy and the ability to switch between different clients at the same time. That was handled flawlessly."
"The most valuable feature of Fortinet FortiSIEM is the user and entity behave as analytics(UEBA). This feature mixes your data and provides useful information based on the behavior of the targeted."
"The solution is the market leader."
"You can integrate Splunk with third-party security automation solutions and set rules for automatic response."
"The most valuable feature is the log aggregation, being able to scan through all of the logs."
"I haven't had the chance to properly sink my teeth into Enterprise Security but so far I like that they added the MITRE ATT&CK features."
"It is very stable. We have not had any problems."
"We are much faster finding and addressing issues with Splunk."
"Splunk has improved our operations by giving us access to more information and allowing us to deploy more use cases."
"The most valuable features are how stable and easy to use Splunk is."
"Sentinel still has some anomalies. For example, sometimes when we write a query for log analysis with KQL, it doesn't give us the data in a proper way... Also, the fields or columns could be improved. Sometimes, it is not giving the desired results and there is a blank field."
"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."
"Everyone has their favorites. There is always room for improvement, and everybody will say, "I wish you could do this for me or that for me." It is a personal thing based on how you use the tool. I do not necessarily have those thoughts, and they are probably not really valuable because they are unique to the context of the user, but broadly, where it can continue to improve is by adding more connectors to more systems."
"Microsoft Sentinel should provide an alternative query language to KQL for users who lack KQL expertise."
"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."
"Sentinel should be improved with more connectors. At the moment, it only covers a few vendors. If I remember correctly, only 100 products are supported natively in Sentinel, although you can connect them with syslog. But Microsoft should increase the number of native connectors to get logs into Sentinel."
"Microsoft Sentinel is relatively expensive, and its cost should be improved."
"We do see continuous improvement all the time, however, I haven't got a specific feature that is lacking or not well designed."
"Sometimes, if there are changes made by a user on a database server, it can be difficult to get that information on the fly. I would like to see a situation where once I specify a user with the database server I need, and with the changes they have performed on that, I don't need to continue my search pattern to drill down just to get the information."
"Customer support service could be better."
"With FortiSIEM, the issue has to do with the ways we can generate a report. It's not as flexible compared to that with other SIEM tools, like Splunk."
"FortiSIEM could be better integrated with other vendors."
"Our customers are noticing configuration available in the GUI interface and I think that they should be equal."
"Not very good on non-API features, lacks that functionality."
"Creating parsers to try make unknown events or currently unsupported devices produce meaningful information is extremely cumbersome."
"Fortinet FortiSIEM could improve to extend to several locations or sites."
"The configuration could be better."
"More training on PetaData using artificial intelligence techniques to identify the events which are not normal and exceptions that would help the organization identify threats and malware on the go with results."
"The solution could use a different licensing model."
"I love the solution, but I would like to see more accessibility to the machine-learning capabilities that are sprinkled around Splunk."
"The monitoring aspect of Splunk could be improved. We have to do some queries to get as much information as CrowdStrike or other solutions provide. If you run a big query, you will see a delay. That is the only concern we have because it will take some time if you query large data sets."
"The product is relatively expensive."
"Spam has different plugins but by default, the logs are not organized, it shows that there are roll-ups that are out of the box. I saw many plugins that can help improve or extend Splunk's functionality but I haven't tried any of them."
"Not even Splunk's support guy, who came to our firm, could help with defining proper role management."
