Network visibility has transformed how we detect nation state threats and protect critical industry
Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale. However, I think with a lot of the artificial intelligence that they are building in, it is getting a lot easier to query in the platform. I would definitely encourage them to continue down that path where anybody can hop into the platform and start running queries, whether it is a simple instruction like I want this, and an artificial intelligence process can actually build the query and do it. I think that would be super powerful. Cyber skill sets are in high demand, and there is a huge backlog in cyber talent. We cannot fill all the positions we need. The easier we can make these cyber systems for people to pick up and be effective on, I think is really key. Explainability of data is hyper important. In the past few artificial intelligence related updates we have gotten from Corelight, that has been one of the first questions our team has asked every time or that I have asked: show me what the model is doing, show me how it came to this analysis. Within Investigator platform, they are able to walk through and see exactly what data the artificial intelligence pulled from where and why it did what it did as far as making its suggestions. They have definitely built their system with artificial intelligence in mind up front, and having that openness as one of the key features of any of their artificial intelligence and machine learning processes in the platform is important. The issue with black boxes is obviously hallucinations from artificial intelligence and just not being able to trace to ground truth. When we are talking about these cyber incidents and being able to do forensics, you need to be able to pinpoint and tie everything together, and black boxes really obscure that and prevent you from doing so. 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.

High cost-effectiveness and reliable alerting ensure proactive network management
Sometimes customers are unaware about their own network. For example, we need SMTP credentials for Layer 2 switches to do automatic discovery of network devices. Sometimes the network management teams are unaware of their SMTP credentials because the teams have been shuffled since the network was deployed. Or sometimes, when we support our government and defense customers, they don't have clearance to share these credentials with us. Some of the features, such as auto discoverability, get hampered if the customer is not aware of their own network or somehow can't share privileges and credentials with our tool for them to work properly. Not in ManageEngine NetFlow Analyzer in particular, but there are other features of the OpManager suite that could afford to be updated. There is something called a CLI, command-line interface, that allows us to configure network devices such as switches. This is old technology. This product suite has CLI-based configurations, but as of last year, most network devices come with Zero Touch Provisioning (ZTP). OpManager does not support this functionality, and we don't really have a timeline on when ZTP functionality will be available. In ManageEngine NetFlow Analyzer, we have to set custom thresholds to get alerted if there is a problem in network connectivity. It would be helpful if we could automate the tool such that we don't have to set thresholds manually, and the tool automatically alerts us when it detects issues. When experts deploy this tool, we already know what thresholds should be normal. But customers in general may not have this skill set. For newer customers who need to adopt this product, an automated method of alerting would definitely be beneficial.
