Harrison Bulley - PeerSpot reviewer
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

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

Pros

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"Icinga does the job and is fairly stable."
"We have found the solution to be stable."
"The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated."
"The apply rules feature saves a lot of time."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"Macros and the ability to connect it to Google Maps are valuable features."
"The product is adept at log mining."
"Splunk stands out for its extensive application integrations."
"It is very scalable."
"The correlation capabilities are the first value that our clients say they like with Splunk."
"To get visibility from your network devices, servers, and security devices is a great feature."
"It gives me notifications of notable events."
"The technical support is among the best in the market."
"Splunk's visualizations make it easy for users to understand the data."
 

Cons

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"The installation and configuration are very complex."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."
"The solution lacks many features important to higher-level IT management and network support."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"We are planning to do certifications, and there are many features, such as risk-based score and score detection, where the current training doesn't provide visibility to the analyst. They should offer training based on the features we use."
"The user experience could be improved."
"Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."
"You do need a lot of training and certification with this product."
"Endpoint access is the only issue I can think to mention, even though the endpoint access we have with Cisco is fine."
"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."
"An area of improvement would be the licensing of the solution. They need a free license, which would allow faster lead times."
"I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team."
 

Pricing and Cost Advice

"It's an open-source solution."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The product is inexpensive compared to other DBM products."
"The solution is free to use."
"The solution is cheap."
"We're using the free version of Icinga."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"This is an open-source solution with paid support."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"Splunk should be able to integrate with other product using the free version."
"The price of Splunk Enterprise Security is high."
"Setup cost is cheap: It is free, it is user-friendly, and it is fast."
"This product could use better pricing in general."
"It is quite expensive."
"In terms of pricing, I believe Splunk is unreasonably costly for the majority of mid and small-sized companies."
"The Splunk Enterprise Security license is expensive."
