Executive SummaryUpdated on Nov 6, 2024

Vectra AI and Corelight are contenders in the network security solutions space. Vectra AI seems to have the upper hand due to its advanced AI-driven alert management capabilities.

Features: Vectra AI offers capabilities like advanced alert management that consolidates alerts into manageable incidents, captures network metadata at scale for enhanced context, and provides functionalities like Cognito Recall and Cognito Detect for improved visibility. Corelight integrates with Zeek for robust open-source traffic analysis, facilitates easy deployment, and enables detailed traffic insights.

Room for Improvement: Vectra AI needs improvements in integrating with external solutions and enhancing its user interface for better engagement. Users seek better logging and visibility on host-driven attacks. Corelight, despite its open-source strengths, requires additional feature development and ease of use improvements. Its complexity can overwhelm and complicate pricing.

Ease of Deployment and Customer Service: Vectra AI is mainly deployed on-premises with hybrid options, boasting strong technical support that enhances customer satisfaction. Corelight, also primarily on-premises, benefits from excellent technical support due to its smaller size, although its scalability might face challenges as demand grows.

Pricing and ROI: Vectra AI's high pricing reflects its comprehensive offerings, delivering a good ROI by reducing attack response time. However, it is less accessible for smaller budgets. In contrast, Corelight's pricing is more affordable and open-source, appealing to technically adept users, though additional investments may be required to maximize its value.

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.

The huge library especially the open source link, makes it the main engine for Corelight with some enhancements in the commercial version. It has a very powerful level, such as signature-based attacks or behavioral attacks, with enhancements in the design. It is very flexible for intelligent implementations like IPs, especially between big companies and banks. Corelight is easy to understand and monitor what is going on behind the team. The solution is already integrated with other systems like Suricata, Elastic, and Microsoft tools. It's very easy to integrate signature-based or behavior-based engines. You can use Elastic for the dashboards to get it from Corelight, along with all the benefits and expandability.

Innovative detection features enhance monitoring

The advantages of the integration are not entirely out-of-the-box. You have to do it manually. When I'm doing tier response, an out-of-the-box solution is not available. You need to have a Linux server, and from the Linux server, you must perform AI tasks, and there is a lot to be handled in the back end. This is a major consideration about them. The recall feature, if it can be placed in some areas instead of the cloud, and charged for, would be better. Recall the storage where you watch all the traffic, and you can recall it and try to analyze it in the back end. It’s cloud-based. If they offer it on-prem, it would be better. I think they have a solution, but I have never tested it, to be honest with you.

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."

"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."

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

"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."

"There are many detection features available."

"The solution is currently used as a central threat detection and response system."

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

"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."

"Some valuable features of Vectra AI are that it is very intuitive and that there are only a small amount of false positives. Therefore, it's an effective solution."

"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."

"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."

Cons

"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."

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

"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."

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

"I would like to see a bit more strategic metrics instead of technical data. Information that I could show to my executive management team or board would be valuable."

"The main improvement I can see would be to integrate with more external solutions."

"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."

"Some of their integrations with other sources of data, like external threat feeds, took a bit more work than I had hoped to get integrated."

"The solution has not reduced the security analyst workload in our organization because we still need to SIEM. Unfortunately, while Vectra, for us, is a brilliant tool for network investigations, giving wonderful visibility, it doesn't go the whole way to replace our SIEM that is needed for compliance. So, I still have the same amount of alerting and logging that I did before. It gives us more defined ability to see incidents, but it doesn't give us enough information to satisfy a PCI or 27001 audit."

"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 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."

"Neither Vectra nor Darktrace have a function like a status health check on my log sources and traffic sources."

Pricing and Cost Advice

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

"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."

"The solution's pricing was 50 percent lower than the other vendors shortlisted."

"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."

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

"Its cost is too much. It's an investment that we can afford. It's a lot, but it's worth it."

"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."

"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."

What is the biggest difference between Corelight and Vectra AI?

The two platforms take a fundamentally different approach to NDR. Corelight is limited to use cases that require the eventual forwarding of events and parsed data logs to a security team’s SIEM or data lake. You then rely on an open-source community for things like detections. Vectra not only does that – but also enriches the underlying data. It is also delivered as an investigative workbench that includes out-of-box detections that highlight and prioritize attacker behaviors and campaigns. Perhaps just as importantly, Corelight has few integrations whereas Vectra natively integrates with parts of infrastructure like EDR, orchestration and network security products.

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