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.

Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.

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

"We use Cortex XDR by Palo Alto Networks for its ability to detect based on behavior rather than simple virus scan to prevent malicious activities."
"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."
"The solution's most valuable feature is the user interface."
"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."
"Cortex XDR by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."
"The stability of the solution is very good. We have about 100 users on it right now, and we use it twice a week."
"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"Palo Alto is the best security solution in the market."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
"ReliaQuest GreyMatter saves around 60% of time or resources."
"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 has increased our security efficiency and has also reduced the time it takes us to respond to attacks by about 50 percent."
"The core product provides excellent visibility, but my favorite feature is Vectra Recall."
"It is doing some artificial intelligence. If it sees a server doing a lot of things, then it will assume that is normal. So, it is looking for anomalous behavior, things that are out of context which helps us reduce time. Therefore, we don't have to look in all the logs. We just wait for Vectra to say, "This one is behaving strange," then we can investigate that part."
"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."
"One of the key advantages for us is we define a 24/7 service around it. We use far more of Vectra alerts than we do with our SIEM product because we understand that when we get an alert from Vectra we actually need to do something about it."
"It has to be up there with my favorite security tool set at the moment."
"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."
 

Cons

"The dashboard is the area that needs to improve so that we can have the ability to drill down without having to go elsewhere to verify results."
"Based on our experience so far, its implementation is quite complex."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."
"We would also like to have advanced tech protection and email scanning."
"There's an overall lack of features."
"To jump from the partner to Palo Alto directly was challenging."
"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."
"Areas that have room for improvement include user interface and integration."
"The false positives and the tuning side of it are some things that could use improvement but that could be from our side."
"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."
"Some of the customization could be improved. Everything is provided for you as an easy solution to use, but working with it and doing specific development could be worked on a bit more in the scope of an incident response team."
"One area where there's room for improvement is the absence of a comprehensive TCP recording and replay feature."
"ExtraHop has better features that seem more advantageous when compared to Vectra."
"The UI/UX and detection could be improved. More detections of specific security events could be useful. We've had a few incidents that were not detected by Vectra. The teams are working on it right now, but more detection is always better."
"The rules for threats are not always precise and Vectra AI should improve this."
"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."
 

Pricing and Cost Advice

"The price of the product is not very economical."
"This is an expensive solution."
"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."
"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."
"The price of the solution is high for the license and in general."
"Its pricing is kind of in line with its competitors and everybody else out there."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"The pricing is a little bit on the expensive side."
Information not available
"Vectra AI's pricing is cheaper than that of Darktrace."
"The pricing is very good. It's less expensive than many of the tools out there."
"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."
"From a pricing perspective, they are very commercially competitive. From a licensing perspective, just be conscious that some of their future cloud solutions come with additional subscriptions. Also, if you're outside of the US, you will get charged freight for the device back to your country."
"The solution is low-cost and affordable."
"The pricing and licensing are quite straightforward because they're based on the IP licenses. As a result, they are easy to count."
"The solution's pricing was 50 percent lower than the other vendors shortlisted."
"Vectra's licensing model could scale to our research network, which has multiple, 100-gigabit links."
