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."
"Splunk provides a free version so you can test it before purchasing."
"If you are an enterprise and you need the best service for critical business analysis, Splunk would be one of the best choices."
"Splunk Enterprise Security has helped speed up our security investigations."
"My security ops team takes around 30 minutes to one hour to remediate security incidents with Splunk Enterprise Security compared to a previous solution."
"We use Splunk Cloud as a SIEM solution and to monitor traffic and the network for detection purposes."
"The security part is useful as it helps secure the entire environment."
"The data representation options in the dashboards are excellent."
"I like the ease with which dashboards can be created."
 

Cons

"It's impossible to be integrated on-premise. Broadcom chose to build only on the Cloud."
"The Broadcom support is very bad."
"Its setup is a little bit complex for a distributed environment."
"For us, the area that Splunk Enterprise Security can improve is performance optimization."
"The support that is included with the standard licensing fee is very bad."
"We had an instance when Splunk failed and it took us a couple of days to recover."
"It could be more user friendly, in terms of the end-user experience."
"Splunk's reporting functionality would benefit from enhanced customization capabilities, allowing users to tailor reports to their specific needs for better data visualization and analysis."
"I think the tech support response time could be a bit better. Sometimes I need to wait more than 24 hours for a response to my tickets."
"While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
 

Pricing and Cost Advice

Information not available
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."
"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."
"Splunk is really expensive compared to all the other tools on the market, including Microsoft Sentinel."
"Splunk Enterprise Security is expensive."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
"This solution is costly. Splunk is obviously a great product, but you should only choose this product if you need all the features provided. Otherwise, if you don't need all the features to meet your requirements, there are probably other products that will be more cost-effective. It's cost versus the functionality requirement."
"Splunk Enterprise Security is not at all cost-friendly to be deployed in very small enterprises like start-ups."
