What is the biggest difference between Corelight and Vectra AI?

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 detection or you need to understand insider threats (User Behavior). If you need both then you need both tools.

Gained full visibility and streamlined threat detection through behavior-based insights and AI integration

Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth. We have fine-tuned our security policies and allowed different levels of policies to get rid of those false positives. Currently, we are getting a fairly good amount of incidents that are not false positives or benign, but actionable items. The process is streamlined. In the initial days, the operations used to get involved in a lot of benign and other activities, but now the process is streamlined. We are leveraging the auto-detection and remediation plans. The operations teams are now more involved in other business roles as well, not just looking into the logs and fetching out what's happening there. They have fixed a lot of things. Initially, they didn't have IAC code drift detection, cloud posture management, or security posture management, but they have those now. They purchased different vendors and did a merger with that. They have now Prisma Cloud that gets integrated and now they are working with Cortex Cloud. Everything that was negative has now been addressed, and the product altogether looks to be in a very better and mature shape now. Currently, it's more or less detecting the workloads with AI-based best practices. Since most organizations are consuming AI agents and other things, we are looking forward to seeing what other feature enhancements Palo Alto can support in that.

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

"If the user leaves our premises or network, Palo Alto Traps will still be on that endpoint and will still apply our policies."

"It's very stable. I've never experienced downtime for the ASM console or ASM core."

"I recognize that Cortex XDR by Palo Alto Networks is one of the best products in its category regarding capabilities."

"The most valuable for us is the correlation feature."

"The product has an intuitive dashboard."

"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."

"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."

"Automation and playbooks have helped me significantly, as Cortex Xnor's playbooks predefine the workflow of the automation, such as response processes, alert triggering, and enriching the context, efficiently detecting and blocking malicious attacks with firewalls while eliminating workload and speeding responses for next-generation operations."

More Cortex XDR by Palo Alto Networks pros

"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."

"The most valuable feature is the embedded IDS from Suricata."

"It's an easy way for us to get visibility in a client's environment."

"It is easy to deploy and easy to handle."

"It's easy to create additional dashboards specific to supporting specific tasks."

"Corelight is easy to use."

"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."

More Corelight Open NDR pros

"It keeps up with the network traffic, which is a good thing. It provides more context to plain alerts compared to using an older system. So, it helps an analyst reduce the information overload."

"Vectra was the only tool that picked up almost all the red team penetration activities, helped us detect threats in their initial recon phase before they caused damage, and has significantly reduced the time it takes us to respond to attacks."

"In comparison to some of the other tools that I've come across in this category, I would definitely give it a 10 out of 10."

"I like the way that Vectra AI focuses on the internal network. Nowadays, most of the attackers are already inside, and they can be inside for many years before they start attacking. With normal monitoring, it's quite difficult to find them."

"The most valuable feature for Cognito Detect, the main solution, is that external IDS's create a lot of alerts. When I say a lot of alerts I really mean a lot of alerts. Vectra, on the other hand, contextualizes everything, reducing the number of alerts and pinpointing only the things of interest. This is a key feature for me. Because of this, a non-trained analyst can use it almost right away."

"Most of their use cases, including deployment, are managed by the tool itself, requiring less manual input from our team."

"The automatic filtering that they provide is valuable. The logic inside that makes some detections instead of us is very useful. We are confident that if we are just looking into it and there is nothing, nothing could happen."

"With Vectra, we become more proactive than reactive, more often than not we pick things up before the actual damage can start, and it picks up things that none of our other tools pick up because it's designed to detect things before harm is done, at the initial stages."

More Vectra AI pros

Cons

"Based on our experience so far, its implementation is quite complex."

"However, if you do not have Palo Alto in your environment, you are paying these additional services just for Cortex XDR by Palo Alto Networks, so it is not a cost-effective solution."

"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."

"Traps doesn't work with McAfee. You need to remove McAfee to install Traps. This is very common, and its nothing that should be an issue. Some antivirus engines recognize Traps as an threat component, so maybe they need to shake hands somewhere."

"The product's pricing could be better."

"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."

"It would be good if they could make an exception for applications. Sometimes, it can be a bit of a challenge to make exceptions for certain applications that have been used as rogue."

"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."

More Cortex XDR by Palo Alto Networks cons

"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."

"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."

"Machine learning could be a good improvement, but it's very costly."

"Corelight hasn’t added features in a long time."

"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."

"In the next release, building a graphical user interface would be helpful."

"One thing which I have found where there could be improvement is with regard to the architecture, a little bit: how the brains and sensors function. It needs more flexibility with regard to the brain. If there were some flexibility in that regard, that would be helpful, because changing the mode of the brain is complex. In some cases, the change is permanent. You cannot revert it."

"You are always limited with visibility on the host due to the fact that it is a network based tool. It gives you visibility on certain elements of the attack path, but it doesn't necessarily give you visibility on everything. Specifically, the initial intrusion side of things that doesn't necessarily see the initial compromise. It doesn't see stuff that goes on the host, such as where scripts are run. Even though you are seeing traffic, it doesn't necessarily see the malicious payload. Therefore, it's very difficult for it to identify these type of host-driven complex attacks."

"You are always limited with visibility on the host due to the fact that it is a network based tool."

"Vectra AI could be improved by focusing on all threat types, not only malicious threats or virus threats."

"In comparison with a lot of systems I used in the past, the false positives are really a burden because they are taking a lot of time at this moment."

"I would like to see data processed onshore. Right now, the cloud components, like Office 365, must be processed on servers outside of Australia. I would like to see a future adoption of onshore processing."

"We have a lot of system solutions and integrations with system solutions. Vectra is a type of black box. It implements AI-informed detection mechanisms, but we cannot create system detections. I understand that the product is designed this way, but it would be great if we could create our own detections as well."

"We had another product with Vectra AI and used the MDR solution as an add-on. Initially, it wasn't fully appropriately configured, so we didn't get the expected results. Even once configured correctly, we weren't fully satisfied with its response. The issue was both with their service response and the product's capabilities."

More Vectra AI cons

Pricing and Cost Advice

"Cortex XDR's pricing is ok."

"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."

"The pricing is a little high. It is per user per year."

"Very costly product."

"Cortex XDR by Palo Alto Networks is an expensive solution."

"The pricing is okay, although direct support can be expensive."

"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"It's a yearly fee and depends on what you are looking for."

"The upfront pricing model that we have would have been more beneficial if it had been a recurring license fee, but that wasn't a massive issue for us. It's fairly priced."

"Cost is a big factor, as always. However, I think we have a very good price–performance ratio."

"The pricing is high."

"It's relatively on the pricier side, but when compared to other solutions. It's not the most budget-friendly option, but it can be considered somewhat more cost-effective in comparison to other alternatives."

"There are additional features that can be purchased in addition to the standard licensing fee, such as Cognito Recall and Stream."

"Vectra's licensing model could scale to our research network, which has multiple, 100-gigabit links."

"The pricing is very good. It's less expensive than many of the tools out there."

"Vectra is a bit on the higher side in terms of price, but they have always been transparent. The reason that they are this good is that they invest, so they need to charge accordingly."
