"Without Splunk Enterprise Security, it would be difficult for us to manage and prioritize alerts. There's a potential to lose track of important notifications, and it's essential to our security that we do not miss anything. Splunk has improved our investigations because the reporting and dashboarding make things so much easier. We can provide weekly or monthly reports. I also like Splunk's ability to integrate.""The most valuable features are how stable and easy to use Splunk is.""We saw the granularity that we could get from Splunk far exceeded what we already had. We had the ability to have our security team really focus on the platform and stay within the platform, but they could correlate with a variety of other stakeholders, and our stakeholders were growing.""The solution helped reduce our alert volume.""Internal tracking is helpful because we do not like to deal with multiple ticketing systems, and I am not a fan of ServiceNow. We are able to keep everything internal and utilize Enterprise Security.""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.""Exporting is a good feature. It helps me out when I have to do reports. I do a lot of exporting and crunching of the numbers. Dashboards are okay for showing to the leadership, but for doing statistics and updating tickets, the export feature is very beneficial for me.""It is very easy to use and integrate. There are connectors for every technology."

"Azure Monitor is not user-friendly, and the interface is not exciting. Switching between the dashboards is not easy.""Currently, it seems it's complicated to get the correct information in terms of what to do and how things work.""It's really complex to retrieve or query the logs in Azure Monitor.""Azure Monitor could improve network performance monitoring and make it more advanced.""This solution has fewer features than some of its competitors, so adding more features to it would make it better.""If it is configured incorrectly, you can end up with a huge bill.""Azure Monitor could improve the visualization aspect and integrate better with other third-party services.""The solution's monitoring feature has limitations for analyzing multiple metrics."

More Azure Monitor Cons →

"The biggest problem is data compression. Splunk is an outstanding product, but it is a resource hog. There should be better data compression for being able to maintain our data repositories. We end up having to buy lots of additional storage just to house our Splunk data. This is my only complaint about it.""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.""Splunk ES could have more pre-built integrations and rules. The detection is fairly accurate, but it depends on the rules you create. Splunk's out-of-the-box configuration isn't that useful.""They can incorporate the SOAR solution within the actual product so that we do not require two different products, two different installations, and two different pricing methods. In regards to UBA, I am familiar with the UBA that existed two years ago. I am not updated about it today, but two years ago, UBA required such an amount of data that from a cost perspective, it was not worth it. When you compare it to what you get out of the box with Microsoft Sentinel without additional costs, there is no match.""The price of the solution could be cheaper.""The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex.""The product could be cheaper.""It would be nice if they had a wizard to construct searches, including more complex searches that include math or statistics."

Pricing and Cost Advice
  • "Azure Monitor is a low-priced solution, which is why it would work best on small-scale projects."
  • "The price of the solution is reasonable."
  • "Azure Monitor is a competitively priced solution."
  • "Azure Monitor is one of the more cost effective solutions on the market."
  • "The cost of Azure Monitor application performance should be less expensive."
  • "The licensing is a monthly fee."
  • "I would rate Azure Monitor a two out of five for affordability."
  • "The solution is very costly because you have to pay for various things such as adding to logs and internet alerts."
  • More Azure Monitor Pricing and Cost Advice →

  • "The price of Splunk is reasonable."
  • "The subscription is monthly."
  • "It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
  • "It's a yearly subscription."
  • "This product could use better pricing in general."
  • "The pricing modules could be improved."
  • "This solution is costly. Splunk is obviously a great product, but you should only choose this product if you need all the features provided. Otherwise, if you don't need all the features to meet your requirements, there are probably other products that will be more cost-effective. It's cost versus the functionality requirement."
  • "It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."
