SolarWinds NetFlow Traffic Analyzer and Corelight Open NDR compete in network monitoring and traffic analysis. SolarWinds seems to have the upper hand with its comprehensive bandwidth analysis and integration capabilities, although Corelight offers distinctive cybersecurity features leveraging open-source tools.
Features: SolarWinds NetFlow Traffic Analyzer excels in monitoring network traffic, provides extensive bandwidth analysis, and offers customizable dashboards that integrate with other SolarWinds tools. SolarWinds supports a broad range of protocols and is vendor-agnostic. Corelight Open NDR focuses on visibility and security insights using open-source capabilities like Zeek for network monitoring. Corelight provides strong cybersecurity features and data analysis capabilities.
Room for Improvement: SolarWinds users express the need for better integration with third-party tools, improved system intelligence, and enhanced application visibility. There are issues with its licensing model's inflexibility and technical support responsiveness. Corelight could benefit from simplifying its complex architecture, introducing a graphical user interface, and reducing pricing. Corelight’s feature expansion requires more frequent updates.
Ease of Deployment and Customer Service: SolarWinds NetFlow Traffic Analyzer is primarily deployed on-premises but also offers hybrid cloud compatibility. Its deployment process is straightforward, though complex due to numerous features, and customer service is seen as inconsistent. Corelight Open NDR's on-premises deployments are well-suited for visibility and security, though setup can be challenging. Corelight's technical support is praised for its helpfulness but can be complex.
Pricing and ROI: SolarWinds NetFlow Traffic Analyzer is considered high-priced with a licensing model based on nodes and additional costs for scaling features. Despite its cost, it offers significant ROI through cost management and traffic insights. Corelight's reliance on open-source tools potentially offers a cost-effective solution, though it remains expensive. It may not provide as much ROI as more comprehensive competitors. Its investment return is seen in terms of operational efficiency and network visibility.
I have seen a return on investment, specifically in terms of money saved in storage costs on our cloud because this is hosted on-premises and is utilizing most of the on-prem available storage.
Corelight Investigator is sold as a software as a service license, and sensors are of course a one-time fee with their hardware maintenance.
I believe I have seen a return on my investment with Corelight Open NDR.
There is a return on investment when purchasing SolarWinds NetFlow Traffic Analyzer, as in the long run, there is a return on investments.
I would probably say we are at an eight or nine as far as the quality of support, which I think is very reasonable.
Corelight support was very helpful in showing me some tool sets they have under the covers that allow me to automate that process.
They often say that only premium subscribers receive support within one or two hours.
I would rate support eight out of ten.
I received efficient responses to many questions.
With Investigator itself, Corelight Open NDR is very easy to scale and manage as a business changes.
SolarWinds NetFlow Traffic Analyzer is a scalable solution, and by adding licenses, I can use the same deployment and instance to onboard more elements and nodes.
The license is based on the count of the ports.
I cannot think of any time we have had a serious disruption to anything we have been doing due to some technical issue on their side.
Corelight Open NDR has been very stable as a solution.
The solution is quite stable.
Corelight has done a really good job of making sure that everything is explainable and everything is mapped when it comes to leveraging any of their artificial intelligence features.
I believe what they have done with it, taking an open-source engine and bundling it into an appliance with professional support, was a brilliant idea.
Regarding Corelight Open NDR's AI capabilities, I think it functions like any other product with AI capabilities, as it requires more visibility and has a long way to go.
Ideally, NetFlow should have a robust alerting mechanism.
It should be like a Meraki cloud, where if you are familiar with Meraki devices, you can locate any device directly on the world map.
Deployment needs improvement; the process is complicated, requiring attention to infrastructure settings and installation of components like the origin application server, platform, close storage, and policy agents.
Corelight Investigator is sold as a software as a service license, and sensors are of course a one-time fee with their hardware maintenance.
My experience with pricing, setup cost, and licensing is that it is quite reasonable when it is open source.
provide a rating of nine out of ten
SolarWinds NetFlow Traffic Analyzer's model is quite costly compared to other brands.
The benefits include visibility, as the Suricata engine can scan huge volumes of traffic.
The lightweight aspect and the easy deployment of Corelight Open NDR stand out to me the most because it helps save compute and storage requirements on our side.
Corelight Open NDR is a really powerful platform. Pairing up the sensors with Investigator, you are getting incredibly rich data, which we are also able to further enrich with additional feeds such as CrowdStrike or CISAIAS.
It provides proactive monitoring, rather than waiting for applications to go down due to heavy bandwidth or latency.
This tool provides insights into top utilization applications or it identifies which circuit or application is consuming the most on the complete one-gig circuit traffic path.
The bandwidth indicates the utilization of the devices; if any issue occurs, it triggers an alert for me.
