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 you are looking to deploy a security solution as a whole, this is a good option."

"We can use Cortex XDR to get the entire graph of the incidents from source to destination, and we can take remedial action."

"Cortex XDR by Palo Alto Networks has helped us a lot with securing the whole environment and the whole IT structure, giving us full knowledge of what is happening on the client and enabling us to take action right away from a single point for managing security operations on the hosts."

"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."

"We've had a significant increase in blocking with a decrease in false positives, because it's looking at how the files work, not just a list of files that it's been told to look for."

"The solution's most valuable feature is its ability to rapidly detect certain hardware files."

"The initial setup is easy."

"Traps is quite a stable product. Once it was properly deployed and configured, you have nothing to be worried about."

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."

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

"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 is easy to use."

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

"Our company has seen massive improvements in cybersecurity position for our clients."

"Technical support seems to be good."

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

More Corelight Open NDR pros

"It does a reliable job of parsing out the logs of all the network traffic so that we can ingest them into our SIEM and utilize them for threat hunting and case investigations. It is pretty robust and reliable. The administration time that we spend maintaining it or troubleshooting it is very low. So, the labor hour overhead is probably our largest benefit from it. We spend 99% of our time in Vectra investigating cases, responding to incidents, or hunting, and only around 1% of our time is spent patching, troubleshooting, or doing anything else. That's our largest benefit from Vectra."

"We often use the new feature to create PCAP files from the whole data traffic. It makes it much easier to find network problems such as whether the server is responding to a request. It has nothing to do with security, but it helps a lot to find other problems."

"It has increased our security efficiency and has also reduced the time it takes us to respond to attacks by about 50 percent."

"The most useful feature is the anomaly detection because it's not signature-based. It picks up the initial part of any attack, like the recon and those aspects of the kill chain, very well."

"It's easy to manage, and I love the UX. It's very well designed. When we are looking for something, it's quite easy to find it."

"The packet-capturing feature is very useful."

"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."

"The biggest feature for us, because we are heavy Microsoft users, is its integration with Office 365. On top of Vectra AI, we use all of the Microsoft security platforms, such as Defender ATP and Sentinel. Having full integration and a central platform to look at all of the threats that are coming through from the different platforms is a huge benefit for us."

More Vectra AI pros

Cons

"I have seen lagging with Cortex XDR by Palo Alto Networks. There was one time when we faced a threat actor trying to gain access to our system. When our team utilized the tool, we were all on the same dashboard and we faced a lag issue at that time of around five minutes, which was quite significant."

"One thing that was missing was the integration part. Currently, they don't have out-of-box integration with IBM QRadar, or if they have the integration, the integration doesn't work well."

"The price could be a little lower."

"The connection to the internet has not performed as expected."

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

"In terms of areas of improvement, we have not completed our review of the product. We're also looking at other products. So, it's a little bit hard to tell what could be different because we have not completed the review of this product, but based on our experience so far, its implementation is quite complex."

"There are some false positives."

"Cortex XDR by Palo Alto Networks is a strong tool, but it is true that digesting information sometimes makes the tool go a little bit slower."

More Cortex XDR by Palo Alto Networks cons

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

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

"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."

"It's an expensive solution and the price could be reduced."

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

"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."

"The reporting from Cognito Detect is very limited and doesn't give you too many options."

"I would like to see ways they can look to bring out new cloud functionality without introducing additional costs for them as additional subscriptions."

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

"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."

"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."

"The solution has not reduced the security analyst workload in our organization because we still need to SIEM."

"I think one area that could be improved about Vectra AI is their marketing."

"The rules for threats are not always precise and Vectra AI should improve this."

More Vectra AI cons

Pricing and Cost Advice

"The solution is expensive. It's pricing is on a yearly-basis."

"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."

"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."

"This is an expensive solution."

"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."

"Cortex XDR’s pricing is very reasonable."

"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."

"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."

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 licensing is on an annual basis."

"We have a desire to increase our use. However, it all comes down to budget. It's a very expensive tool that is very difficult to prove business support for. We would like to have two separate networks. We have our corporate network and PCI network, which is segregated due to payment processing. We don't have it for deployed in the PCI network. It would be good to have it fully deployed there to provide us with additional monitoring and control, but the cost associated with their licensing model makes it prohibitively expensive to deploy."

"Vectra's pricing is too high. All schools will not be able to afford it. Vectra will only end up targeting higher education and higher value independence purely because of the price. A lot of schools would love to have a product like Vectra AI, but they simply can't because they struggle to even pay the high E5 licensing from Microsoft. When you're up against that, Vectra AI is never going to be within the sector's price range."

"It is an expensive solution, but it's not the most expensive we've seen. We also know how much we're going to pay, unlike with some other providers where all of a sudden our license explodes."

"The pricing and licensing are quite straightforward because they're based on the IP licenses. As a result, they are easy to count."

"At the time of purchase, we found the pricing acceptable. We had an urgency to get something in place because we had a minor breach that occurred at the tail end of 2016 to the beginning of 2017. This indicated we had a lack of ability to detect things on the network. Hence, why we moved quickly to get into the tool in place. We found things like Bitcoin mining and botnets which we closed quickly. In that regard, it was worth the money."

"The license is based on the concurrent IP addresses that it's investigating. We have 9,800 to 10,000 IP addresses."

"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."
