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.

Correlates incidents, allows for quicker identification and helps prioritize investigations

The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

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

Pros

"The product provides visibility and enables us to correlate data and generate alerts."

"Splunk Enterprise Security's risk-based alerting has been a game-changer for us, adding intelligence to alerts by considering behavioral or internal asset-based criteria, effectively helping us prioritize alerts and filtering out noise that can be ignored."

"Splunk Enterprise Security offers two valuable features: the Common Information Model and arrangement modules."

"My favorite example of improving of organization is saving a $60k/mo in payroll fraud and $10k/mo in wasted API credits by using simple searches and clear reports."

"We evaluated several solutions and selected Splunk due to the functionality and cost."

"The security part is useful as it helps secure the entire environment."

"The main advantage of the solution is that it provides an easy setup platform in the new environment."

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

"Its reporting can be improved. That's the only complaint I have heard. I don't need the reporting part, but I know that other people in the organization need it."

"A lot of people are averse to using new tools so if they make it even more user-friendly than it already is, I think that could go a long way."

"The Web Application Firewall will send you too much information because it's more dedicated to security than a normal firewall."

"The solution could improve by increasing the performance. We have run into problems when large amounts of data are processed."

"The technical support can be improved because sometimes when we call them, the issues are not resolved immediately and tickets take time to be addressed."

"There is a learning curve in order to start using machine learning. We have been trying to do it for three years, and we have not managed anything. It is too complex."

"This is a costly solution."

"I think the machine learning should be emphasized. Now, it's really important to analyze Big Data, data mining. A SIEM solution, like Splunk, needs an improved data mining solution, artificial intelligence."

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

"Splunk Enterprise Security is not a cheap product, but I think it is worth every dollar that you pay."

"I have no opinion on pricing."

"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."

"The price of this solution is expensive. However, it has great features. If you want a great solution you need to pay a price matching the features."

"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."

"I work on the technical side, so I don't know precise figures. However, I know that Splunk is a premium product, so it's somewhat costly. Still, you get a lot of unique features for the money."

"Splunk Enterprise Security is expensive."

"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."

"It’s a single license platform."
