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.

AI‑driven threat detection has transformed alert fatigue and now enables faster response and leaner soc operations
The best features of Vectra AI are related to AI. For the NDR part, Attack Signal Intelligence features were mainly responsible for behavior AI, high-fidelity signaling, and prioritization. These features were great for anomaly detection and behavioral-based detection, able to catch zero-day attacks and living-off-the-land attacks. For high-fidelity signaling, it automatically triaged, filtered, and correlated signals, which dramatically reduced alert fatigue noise on the customer side by approximately 80% and eliminated alert fatigue on the SOC teams. Regarding the identity detection and response IDR solution, it monitored Active Directory and Entra ID for any attacks, allowing the SOC to detect any compromised credentials. Alert noise was dramatically reduced by nearly 80%, allowing SOC analysts to focus more on true threats, which made them more productive and resulted in higher operational efficiency. Attack Signal Intelligence helped reduce irrelevant alerts by 80% to 90%, with metrics showing a 100-plus reduction in investigation workloads and roughly saving about 55,000 hours of investigation time. Investigation time has decreased significantly, empowering analysts with detection and advanced unknown threats that Vectra AI provided. Its knowledge base and database are very up to date, allowing for spotting zero-day attacks with full visibility and helping to stop attacks in minutes. Vectra AI has reduced the MTTD and MTTR, increasing operational and process efficiency, and has helped reduce the number of SOC analysts that needed to be hired. Thanks to the AI features, the number of employees and SOC analysts hired has been reduced.

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.
