Automates threat response and reduces investigation time but needs better threat intelligence integration
One thing that we would like to see with Splunk SOAR is the expandability to the threat intelligence feed. Currently, we have limited ingestion to the threat intelligence feed for the correlation purpose. We would like to see it being integrated, with license cost or without license cost, to leading threat intelligence sources such as Recorded Future, Feedly, or Flare. That is something we would appreciate having integrated. The second thing on the improvement side is about exposed credential-related information. If we start ingesting those data to Splunk SOAR or SIEM with some sort of integration with threat intelligence feed, that will also improve our detection and prediction method or help us with the investigation.

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

"So far, the interface is very easy to use."
"Surprisingly, the mobile app is valuable because it is very convenient for our on-call analysts to respond and get alerted to security alerts and events wherever they are. We are able to harness the power of Splunk SOAR and everything that we are doing, and we are also able to alert our on-call analysts 24/7. From their mobile phone, they can respond to those alerts."
"When you design a playbook, you can integrate multiple log sources and define rules... After that, the platform automatically compiles all these activities and, based on the results, the analyst only has to indicate whether the result is a true or false positive. That reduces the time and effort involved."
"The features of Splunk SOAR that I appreciate most are the integrations with all the other applications and tools."
"Splunk has many features that make work easier, and it's simple to implement in a large production environment. Splunk collects a massive amount of data from cloud servers and handles it perfectly."
"The customization of the playbook in Splunk SOAR is very beneficial."
"The playbooks are valuable. They are the core component. Being able to implement and build a code process to work through and scale out what we want to do is valuable."
"Before its use, analyzing each email would take at least 15 to 20 minutes, with some complex cases taking up to 30 minutes...With the automation provided by Splunk Phantom, we could significantly reduce the amount of time and human effort required to complete this task."
"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

"What we have seen is if the workflow gets halted or if we want to halt a workflow, it cannot be resumed."
"We've run into a few minor issues. Some of the playbook writing is a bit complicated. We've had a few hiccups with the source control. We'd really like to use GitHub deployment keys for a dedicated account. We haven't been able to do that. I think those are some of the major ones."
"have put a number of ideas on the ideas.splunk.com site for feature requests for the Splunk SOAR product. I posted one of them about three years ago, which finally got implemented in the latest release that just got announced, so the time to implement new features and things like that is a little bit concerning."
"The scalability could be better."
"The solution must provide more AIOps to improve predictability."
"SOAR is probably the most unreliable product Splunk has and that's because most of it is content driven from what you put into it. There are certain parts of it that have a little bit of difficulty at volume too. It's always changing. There is new stuff coming out for it that's going to make it a little bit better, but it does have some drawbacks."
"Some of the training materials are on a basic level."
"It would be ideal if we could automate processes even more."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Splunk is a fast enterprise tool, but it costs too much. At the same time, it's worth what we pay, in my opinion. We can efficiently perform all the functions and tie together the data. It's the perfect tool for our needs."
"When we first purchased our Splunk SOAR license, it was based on an event-count model. It was based on the number of events. I had strong opinions at the time that automation should not be stifled by the amount of automation you can accomplish, so the previous structure was not as beneficial for us. Later that year, we got told or saw at a conference that they announced user-based pricing. We are now in a renewal period, so we migrated to a user-based license model, which is more appropriate for us so that we no longer have to worry about stifling our automation based on the quantity."
"Splunk SOAR is more expensive compared to other options for SOAR."
"We renewed it this year. This year was the first time there was a dramatic increase in the price. It was kind of non-negotiable. It was just a high increase. We had internal communications, and it was definitely a surprise to us. In a short time frame, we renewed it this year. Prices are going up everywhere, but they are not always justifiable, at least not to our eyes. The pricing this year was definitely a big shock."
"The tool is not cheap."
"The cost is high and the licensing is on an annual basis."
"It's very overpriced because it is based on the number of users. There is no bulk licensing."
"Splunk SOAR is moderately priced, neither cheap nor overly expensive."
"It’s a single license platform."
