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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

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

"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"Its interface and pricing are most valuable, and it is better than other vendors in terms of security."
"One of the things that I enjoy the most is using policy extensions. It's like having host firewalls to control USB connections. I think it's a wonderful tool to restrict use when connecting to our computers. Another important tool is Home Insights. That is an add-on to the Cortex solution. I like that because we can see all the vulnerabilities in the environment and control what assets are connected to our network."
"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"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 multi-layered approach to the product gives you confidence that it will stop exploits, ransomware, worms, or viruses from compromising endpoints, essentially providing peace of mind."
"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."
"The solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
"The most valuable feature for Cognito Detect, the main solution, is that external IDS's create a lot of alerts. When I say a lot of alerts I really mean a lot of alerts. Vectra, on the other hand, contextualizes everything, reducing the number of alerts and pinpointing only the things of interest. This is a key feature for me. Because of this, a non-trained analyst can use it almost right away."
"It has increased our security efficiency and has also reduced the time it takes us to respond to attacks by about 50 percent."
"Most of their use cases, including deployment, are managed by the tool itself, requiring less manual input from our team."
"After we deployed the solution it instantly began to add value to our security operations."
"Cognito Streams gives you a detailed view of what happens in the network in the form of rich metadata. It is just a super easy way to capture network traffic for important protocols, giving us an advantage. This is very helpful on a day-to-day basis."
"The solution's ability to reduce alerts, by rolling up numerous alerts to create a single incident or campaign, helps in that it collapses all the events to a particular host, or a particular detection to a set of hosts. So it doesn't generate too many alerts. By and large, whatever alerts it generates are actionable, and actionable within the day."
"If I look at the value I can extract from every Euro that I spend on Vectra, and compare it to every Euro I spend on other solutions, the return on investment on Vectra is way better."
"Vectra has saved us weeks, if not months, in terms of the ability to identify a breach."
 

Cons

"The solution should enhance the ADR and reporting."
"To jump from the partner to Palo Alto directly was challenging."
"The solution should offer more dashboards and they should be better customized."
"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."
"If they had pulse rate detection, it would be better."
"The negative aspect I see is the economic model used by Palo Alto."
"Previously, the endpoint would leave the environment, not being on our VPN, essentially unable to interact with the server to upload files. It was unable to retrieve new file verdicts. It was using a thing called "local analysis" to determine if something was a malicious file or not. There was no dynamic analysis."
"In some cases, there are too many options for me, and it is a bit too hard to find some settings which I really need to implement."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Pricing could be improved, as many customers have complained about the pricing model and pricing complexity."
"Some of the customization could be improved. We think the integration with source solutions could be better."
"There is room for improvement in the documentation. We would like to have more details on how it detects what we see."
"I'd like to be able to get granular reports and to be able to output them into formats that are customizable and more useful. The reporting GUI is lacking."
"Neither Vectra nor Darktrace have a function like a status health check on my log sources and traffic sources."
"The advantages of the integration are not entirely out-of-the-box. You have to do it manually."
"Integration with other security components needs improvement. It should have true integration as opposed to just being a separate pane of glass."
"The rules for threats are not always precise and Vectra AI should improve this."
 

Pricing and Cost Advice

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"Cortex XDR's pricing is ok."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"This is an expensive solution."
"Our customers have expressed that the price is high."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"This is an expensive solution."
"It’s a single license platform."
"The licensing is on an annual basis."
"There are additional features that can be purchased in addition to the standard licensing fee, such as Cognito Recall and Stream."
"Vectra AI is not a cheap solution."
"Vectra AI's pricing is cheaper than that of Darktrace."
"From a licensing perspective, the Vectra detect platform is pretty doable. Also, the hardware prices are nothing that we're not used to. The stream part is a little overpriced compared to the detect part. The reason is that you need to stream data to detect events anyway, so the data is in there. The only thing that's not available is the UI to be able to look at the stream data, which is also on the appliances but is just not activated. That's mainly the thing that we want to improve on."
"The solution's pricing was 50 percent lower than the other vendors shortlisted."
"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."
