Global Head of Monitoring at AXA Investment Managers
Good performance, efficiency, and focuses on monitoring
When you choose a solution, you compare the bad points and the good points with the requirements that are needed. DOI does have some bad points. The real bad part is that it's impossible to be integrated on-premise. Broadcom chose to build only on the Cloud. In the beginning, I first started to check on-premise solutions to integrate in the future with Cloud models. So when we chose DOI, we knew the bad point was its obligation to use the Cloud or the SaaS model. But it's not a bad point now because Cloud and SaaS computing is the future of IT. But it's too early to really know about the security and what the other companies are seeing and changing. Monitoring information is critical for a company - information about the IPs, names that we keep, and some technical information. Also critical is the security of the monitoring itself. Broadcom manages the security of the data well. If you have securable monitoring and your team is already using Century or other products, DOI is not a good choice because DOI is not open-source. DOI is a static solution so you will not have access to the code. It is difficult with Sharepoint, too. If you are not in the habit of managing your static Broadcom relationship, it's not easy. The support is in India and it's already closed by the midday shift. The Broadcom support is very bad. I had a previous integration of Broadcom and their static software. But I was able to manage the support. But for new customers, it's quite difficult to create this relationship. Please keep in mind, Broadcom is a very huge company and when you're small or medium, about 1,000 or so employees, if you don't have the team, monitoring will be difficult. If you start a new company or are a startup, don't use Broadcom software. You don't have the weight to negotiate with Broadcom. It's not a bad point with DOI, just a bad point with the Broadcom relationship. But if you only choose DOI, keep in mind that the product is not only its technical capabilities, but also it's support relationship with the enterprise. We already plan to integrate automatic recognition in future releases. Now we don't use a major part of the automatic recognition. The plan is to create or automatically correct some command execution or re-run of the image and to integrate the VPN. The next step is to use the automatic recognition and to bypass the human intervention and to have automatic intervention of the critical system.

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.

Quotes from Members

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

Pros

"The features that I have found most valuable are the machine learning and the algorithm. We tried seven solutions. The good points of DOI are performance and efficiency under machine learning systems."
"We chose DOI because during the proof of concept, the integration of all of our asset management and monitoring payments took three days, which was very short, very quick, and very efficient compared to other solutions where we spent around three or four weeks on integration."
"The most valuable features of Splunk Enterprise Security are the enterprise search bar and the dashboards."
"It provides a great range of plugins and one can really take great advantage of utilising inbuilt dashboards to derive the desired monitoring."
"The solution's most valuable features are its ability to transact in the cloud and its ability to onboard data easily with minimum connectors."
"It allows us to digest the information, the data, the different data streams, so we can make decisions based upon information that we receive, and it is pretty robust."
"Splunk Enterprise Security has positively impacted my organization by speeding up our ability to respond to security threats, improving my response time from a time span of months to a time span of days."
"Splunk Enterprise Security is doing its job in helping improve my organization's business resilience."
"The product is good, it satisfies our customers."
"It has been really good at consolidating a lot of data from different sources. It's really good at generating summaries."
 

Cons

"The Broadcom support is very bad."
"It's impossible to be integrated on-premise. Broadcom chose to build only on the Cloud."
"I want Splunk Enterprise Security to release more AI and machine learning features in the future."
"It needs more thoroughly tested releases. Every new big version (6, 7, etc.) has had so many bugs that it makes me wary of customers upgrading right away."
"Unlike other cloud based analytics platforms, at the time of this writing Splunk Cloud is a dedicated instance per customer rather than a shared tenancy platform."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
"It can be easier to setup and adding new sources which Splunk are improving with every new version."
"Its reporting can be improved."
"While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
"It could be more user friendly, in terms of the end-user experience."
 

Pricing and Cost Advice

Information not available
"Pricing and licensing are quite high compared to other tools or SIEM tools, but the features justify it."
"Pricing and licensing is quite expensive. But for the value the product provides, it seems at par in the market."
"The tool's pricing model is great. You can choose between workloads or volume."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"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."
"Its pricing model can be improved."
"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."
"Further reductions would be fantastic, and I believe that more and more people would flock to it."
