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.

Unified security monitoring has simplified incident response and improved automated threat handling
The firewall side can make some improvements. I know the firewall on Cortex XSIAM is based on Windows. From what I have experienced so far, I have seen that the policies you can create are actually very in-depth. I mean, you can do most of the things and a lot of integration that you actually want. So if I want to choose to send things to WildFire, for example, I can choose to send it, I can choose to not send it. This basically offers flexibility to implement Cortex XSIAM in more standardized places where you maybe have a certification. I would say that the thing that maybe needs a bit more improvement is the fact that the one with the firewall because I have seen some things there that are kind of hard to manage. You do not really have a very easy way to manage those, unless you actually know where you have put them. So it is very inflexible. In the rest, you have a lot of playbooks that you can do and you can do lots of automation, which is actually easy to manage from what I have seen from my colleagues.

Quotes from Members

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

Pros

"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."
"It's very stable. I've never experienced downtime for the ASM console or ASM core."
"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."
"Palo Alto Networks Traps improves our security posture and lowers risk by providing next-gen methods to combat against modern threats on all the major platforms."
"The main benefit of using Cortex XDR by Palo Alto Networks while employing Palo Alto Firewall at the internet edge is that it improves security on our endpoint devices, integrating seamlessly with Palo Alto Firewalls to deliver comprehensive network, analyst, and security details all in a single dashboard, which allows us to manage everything from our network devices."
"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."
"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"The solution allows us to make investigations. Other XDR solutions also provide similar capabilities but for investigation, Cortex XDR is better."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Corelight is easy to use."
"Our company has seen massive improvements in cybersecurity position for our clients."
"It's an easy way for us to get visibility in a client's environment."
"Technical support seems to be good."
"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 is easy to deploy and easy to handle."
"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."
"The most valuable aspect is that Cortex XSIAM doesn't generate excessive alerts, refines all search results effectively, and filters out incidents where SOC intervention isn't necessary, allowing engineers to focus only on what matters."
"Since implementing Cortex XSIAM, incident response times have been significantly reduced by approximately twenty percent."
"I would give Cortex XSIAM a rating of ten out of ten."
"The way the solution responds to detections and warnings is really impressive."
"The advanced visualization capabilities of the product are important for understanding security trends in an organization."
"It is an effective solution in terms of performance and functionalities."
"The most valuable feature is the integration capability."
"It operates on a single, extensive database which enables it to excel in detecting threats and anomalies across the network and endpoints, delivering a highly effective and comprehensive security solution."
 

Cons

"Data privacy is a matter of concern. You have to be careful with data privacy, it can be sensitive and Cortex can have most of your access."
"It would be better if they could educate the customers more. Some sort of seminars and roadshows will help educate the customers and show what the product can do. The price could be better. It would also help if they had a team for deployment and support."
"Product might have some bugs."
"If you compare it to SentinelOne, which has more functionalities and detection capabilities on an open platform, the pricing on SentinelOne is far more reasonable and cheaper than Cortex XDR by Palo Alto Networks."
"The solution could improve by providing better integration with their own products and others."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"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."
"It would be good to have a better way to search for a file within the UI."
"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."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"In the next release, building a graphical user interface would be helpful."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Corelight hasn’t added features in a long time."
"Machine learning could be a good improvement, but it's very costly."
"It's an expensive solution and the price could be reduced."
"It could provide more integration with a large variety of products."
"The first impression is that XSIAM would be more expensive than others we tried."
"At the beginning, we experienced some difficulties setting up the product with connectivity and infrastructure, but ultimately it functioned really effectively."
"Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports."
"The solution’s pricing and technical support could be improved."
"There is room for improvement in expanding integrations to include more cybersecurity solutions."
"The support could be a bit faster."
"I am not sure if any improvements are needed right now."
