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.

Quotes from Members

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

Pros

"The most valuable feature is the embedded IDS from Suricata."
"It is easy to deploy and easy to handle."
"Corelight Open NDR has had a positive impact on my company, providing visibility as the Suricata engine can scan huge volumes of traffic, including north-south and east-west, revealing signatures and exposures I was not expecting and enabling me to catch them with Suricata alerts."
"Corelight makes much easier the remediation of cyber attacks; instead of facing a chaotic amount of logs, Corelight provides correlated metrics that allow pivoting to find, in seconds, all the data related to an alert, detection, or asset."
"Our company has seen massive improvements in cybersecurity position for our clients."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Technical support seems to be good."
"It's an easy way for us to get visibility in a client's environment."
"Kerio Control has helped my organization by hiding my private IP address behind the firewall and we use the proxy destination instead of my website."
"The initial setup is a breeze."
"The most valuable features include geo-tagging, which blocks all other IPs except for the specified accounts, and web filtering."
"Only trust in the product."
"The solution provides feasibility regarding cyber privacy."
"Now that we're both running fiber connections between Sydney and Adelaide, I can access our document server in Adelaide just from my PC, rather than using something like TeamViewer and transferring the file I'm after via TeamViewer from Adelaide."
"One thing we always tell our customers is that we have never had a client using Kerio Control and the antivirus tools that we suggest who has been infected with any type of ransomware."
"The product is easy to use."
 

Cons

"Machine learning could be a good improvement, but it's very costly."
"In the next release, building a graphical user interface would be helpful."
"It's an expensive solution and the price could be reduced."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"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."
"Corelight hasn’t added features in a long time."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"The reliability is its biggest downfall; I don't expect to be rebooting a product like this every couple of days."
"Technical support is not the best. As an example, this past weekend I had an issue; it took me four days to get a hold of their support team, and I'm a premium client."
"Effectively, I can't use the WiFi facility in the appliance and had to purchase a separate web that supports VLANs."
"If you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly."
"I would like to see a little improvement in their technical support when you have a problem. I may be a little jaded because I came from Kerio when we could call and get a person on the phone who worked on the product. Every tech had their own demo setup. They had instant messaging capability with the developers. If we found a problem, then we could get a result for it quickly. Now, the product seems to be 24 hours. They have also gone to the model that if you need quicker support, then they now charge you additional for the exact same level of support that they used to give. I am assuming it's the exact same level of support that they say it is. I'm not paying extra for it. That's the biggest flaw with the product."
"Kerio Control could improve content filtering."
"If you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly. Some of my colleagues, in the beginning, jumped in and made a bunch of rules but then it got really messy. If Kerio had a template or guidelines for best practices, at the beginning, that would really help. With Kerio Control it's basically 'find out for yourself.'"
"The stability is pretty good. I've only had one issue with it before. It was set to update on its own, and it didn't update and the update failed, so it didn't come back on for some reason."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"The pricing is in-line with our expectations in terms of the quality that we get for it."
"It is priced low enough for entry-level, but it has the power to grow with a company without them having to replace it."
"It's pretty expensive in licensing costs, especially if you use the product longer than one or two years. The licensing costs are still high, which I don't think is reasonable for a product like this."
"It gets expensive pretty quickly if you need to purchase license packs."
"Licensing is easier with Kerio Control. With FortiGate, we realized the licensing is really hectic, because if you skip one year, you have to back pay that year. If you skip two years, you have to back pay two years. With Kerio Control, if a license expires, one year later you can just reactivate and go on."
"My advice is to use your own hardware, and do not use theirs."
"I think it is a bit on the pricey side, but it's okay. I've got 50 licenses which I think is $250 a year or something like that."
"I pay approximately $50 for the solution on an annual basis."
