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.

Threat detection has improved and malicious emails are now identified quickly
Vectra AI offers artificial intelligence capabilities with visibility that can be integrated into our day-to-day operations and other tools, including malware detection tools and cyber threat tools. Vectra AI has positively impacted my organization. Last year while using it, we received many malicious email threats and virus incidents, including a trojan virus that had reportedly been deployed by someone. Our company used Vectra AI to detect the malicious threats and viruses before they could cause more damage, and we successfully stopped the threats. Using Vectra AI, I notice that server downtime has decreased significantly. We now experience only two to three hours of downtime, whereas without Vectra AI and other tools, our downtime would exceed 48 to 72 hours.

Quotes from Members

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

Pros

"It is easy to deploy and easy to handle."
"Corelight is easy to use."
"Technical support seems to be good."
"It's easy to create additional dashboards specific to supporting specific tasks."
"It's an easy way for us to get visibility in a client's environment."
"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."
"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."
"It is easy to deploy and easy to handle."
"We particularly like the user experience around the dashboard, which we find to be much more straightforward than the dashboard of some of the competitive products... Vectra is a really easy system to understand and use to prioritize where we need to focus our security resources."
"Vectra has saved us weeks, if not months, in terms of the ability to identify a breach."
"The UI is easy to use and when we send detection to everybody, they easily understand what we are asking at the time."
"Most of their use cases, including deployment, are managed by the tool itself, requiring less manual input from our team."
"Vectra is very compatible with various cloud providers, such as Amazon and Azure AD. This is helpful as customers often migrate their network infrastructure to the cloud."
"Vectra AI enables you to see more; it is their visibility strength that makes the platform so great."
"One of the things that we didn't expect to happen was that our network team also jumped on it faster than we thought. In most cases, if it's a security tool that's working on the network part, they can also use it to find out certain flaws that have been in the system. Certain flaws, related to some legacy stuff, were already there for quite a few years, which they couldn't explain at first, but we could explain them based on the timing of certain things."
"One of the most valuable features of the platform is its ability to provide you with aggregated risk scores based on impact and certainty of threats being detected. This is both applied to individual and host detections. This is important because it enables us to use this platform to prioritize the most likely imminent threats. So, it reduces alert fatigue follow ups for security operation center analysts. It also provides us with an ability to prioritize limited resources."
 

Cons

"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."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"Machine learning could be a good improvement, but it's very costly."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Machine learning could be a good improvement, but it's very costly."
"In the next release, building a graphical user interface would be helpful."
"One of the things I am not so happy about when it comes to Vectra is the scoring board."
"We would like to see more information with the syslogs. The syslogs that they send to our SIEM are a bit short compared to what you can see. It would be helpful if they send us more data that we can incorporate into our SIEM, then can correlate with other events."
"If you hit a certain number of rules, triage filters, or groups, the UX responds more slowly. However, we have a complex network and a lot of rules. So, our setup might not be a typical implementation example. We even had UX engineers onsite, and they looked at issues, improvements, and user feedback. Since then, it has gotten a lot better, they even built in features that we specifically requested for our company."
"An area for improvement in Vectra AI is reporting because it currently lacks some details."
"Other alternatives, like Darktrace, have a fancier UI."
"I would like to see ways they can look to bring out new cloud functionality without introducing additional costs for them as additional subscriptions."
"Some of the customization could be improved. Everything is provided for you as an easy solution to use, but working with it and doing specific development could be worked on a bit more in the scope of an incident response team."
"Vectra is still limited to packet management. It's only monitoring packet exchanges. While it can see a lot of things, it can't see everything, depending on where it's deployed. It has its limits and that's why I still have my SIEM."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"The pricing is very good. It's less expensive than many of the tools out there."
"My company pays for the Vectra AI licensing fee yearly. I know the figure because my company recently renewed the license, and it's okay, at least for the financial sector."
"From a pricing perspective, they are very commercially competitive. From a licensing perspective, just be conscious that some of their future cloud solutions come with additional subscriptions. Also, if you're outside of the US, you will get charged freight for the device back to your country."
"Vectra AI's pricing is cheaper than that of Darktrace."
"The solution's pricing was 50 percent lower than the other vendors shortlisted."
"The pricing is high."
"The licensing is on an annual basis."
"The pricing and licensing are quite straightforward because they're based on the IP licenses. As a result, they are easy to count."

Corelight is a Zeek based solution for network behavior analysis and Vectra AI is a User Behavior based solution. If you are comparing these 2 systems you are comparing apples to oranges. You shouldn't be evaluating these products against each other as they address different use cases for your network. My guess is you are either looking for better network visibility and possibly network dete...

I would recommend you look at Darktrace instead. Extrahop and the new kid on the block, Awake security are also recommended.
