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

"The varied prebuilt feature is the most valuable because it ensures that we have complete coverage over all of the key questions."

"Support is quick and competent."

"We can automatically suspend or terminate suspicious sessions."

"It provides logs in one place, so they are easy to find. It collects the logs from multiple places, then you have just one place where you see the whole flow from the front-end to the back-end."

"We can present to our management in real time the security of the batch management for the PCs, security regarding the network equipment. We're currently working in the Azure Cloud project, so we can send any logs from the cloud to Splunk. We can monitor them and we can present to the managers and customers. It's a very good solution for reporting. We use Splunk for reporting and monitoring of any solution in the company."

"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."

"The correlation searches (properly configured) populate the Incident Management dashboard and provide me a quick birds-eye view of my most important concerns."

"The features I appreciate the most in Splunk Enterprise Security are the scheduled alerts and the search function."

More Splunk Enterprise Security pros

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

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

Cons

"The incident response dashboard could be more user-friendly."

"We do have to educate developers on how to not blow it up. It is a little to easy to write an expensive query and overly stress the system. This could be improved."

"I encounter issues such as downtime, bugs, glitches, and unbox errors."

"Its performance can be better. Sometimes, it takes longer when we do queries."

"Being a SIEM solution with a centralized dashboard, we would like to have more options to customize it."

"The prices are complicated as we operate in a small third-world country."

"The implementation and the scanning of the logs can be difficult."

"There is a definite learning curve to starting out."

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

"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."

"I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."

"Its price is fair. Like with anything else, if you go into the cloud, different providers cost more, and you are able to throttle back or throttle up. The cost is comparable with anything else."

"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."

"I have no opinion on pricing."

"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."

"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."

"It is expensive. That is why many customers have moved to IBM QRadar. The price is definitely a challenge for customers."
