Helps us detect cyber threats quickly and integrate multiple feeds effectively

Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Automated security monitoring increases efficiency, but market visibility needs improvement

I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"You can use it to gather syslog messages from anything."

"The flexibility of the search capability is most valuable, and you can use it for more than just a basic log aggregator, which makes it powerful in that regard."

"It provides a lot of analytics with the underlying AI engine, and it is a lot easier than other solutions. There are some products that do automated AI-based detection and drawing up charts, but for network monitoring and all of the monitoring aspects, it is quite a nice tool. It is very convenient for business users because they get more or less a lot of data readily available. If you're familiar with the Splunk query language, you can pretty much do whatever you want."

"Splunk Enterprise Security has helped improve my organization's business resilience by fulfilling gaps in forensics, incident management, IRP, and data management while helping us mature our security operations."

"The additional vendors we've brought on board, particularly the elastic, have been quite beneficial."

"Splunk is one of the most powerful SIEM platforms due to its flexibility, scalability, and advanced search capabilities as it uses the SPL language."

"We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used."

"It has a low barrier to entry, but it is extremely extensible, allowing it to be tailored to highly specific use cases."

More Splunk Enterprise Security pros

"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."

"It can integrate with almost any cybersecurity tool available in the market."

Cons

"For instance, if a DLP operations analyst accesses the platform, it should guide them to navigate predefined content for their role. That's something I've already mentioned to them, and I'm eager to see what happens next."

"Splunk Enterprise Security provides us with the relevant context to help guide our investigations, but it would be interesting to add even more context, for instance, in order to raise the level of risk."

"To improve Splunk Enterprise Security, I would suggest allowing third-party SOAR solutions to work with it."

"I'd like a dashboard that allows me to connect elements through drag-and-drop functionality."

"My company could benefit from doing more Splunk training with Splunk consultants teaching us how to use it."

"It is a good product, but the Achilles heel for a lot of organizations is the cost model for it because it gets expensive. That's because the model is based on how much data it processes a day, which can be prohibitive, especially if you have a lot of data. A lot of customers may not be ready for the sticker shock on how to fully leverage the product. I realized that the reason for that is that when it was originally designed, it was kind of like a big data modeling application. If they want to have a bigger customer base, they can come out with subsets of their product that are focused on specific things and have different pricing models. It may help with the cost."

"When we were trying to implement an enterprise solution on-premise, we had scaling issues."

"The technical support here in South Africa hasn't been great, but I understand why as we make up less than 3% of Splunk's total revenue in the world."

More Splunk Enterprise Security cons

"Support is an issue because they have a limited number of resources."

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."

Pricing and Cost Advice

"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."

"Splunk Enterprise Security is priced lower than competitors."

"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."

"The price is comparable."

"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."

"Pricing can be a limiting factor. You have to continuously tune what you are bringing in and make sure what you bring in is of value."

"Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult."

"Splunk is not free."
