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.

Reliable and good support but can be expensive
I have no real complaints about the solution. Threat detection could be better. They need to enhance their threat intelligence feeds. We would like to have more IOCs or more trade intelligence to not only rely on the intelligence of the engineer in charge but to have some threat intelligence and some seeds of IOCs and to have the host have some artificial intelligence to reduce the number of false positives. I don't see this solution being very scalable. The solution is pricey.

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.

Quotes from Members

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

Pros

"The most valuable feature of Cortex XDR by Palo Alto Networks is its machine-learning capabilities. Additionally, there is full integration with other solutions."
"The tool is designed to scale for large enterprises and handle large volumes of data."
"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."
"Stability is a primary factor, and then there's the ease of distribution and policy management; Cortex XDR by Palo Alto Networks is very easy to work with, and we're quite happy with them."
"The product has an intuitive dashboard."
"There are a lot of lead solutions in this space, however, Palo Alto is number one."
"The stability of this product is very good."
"I like that the product has behavior-based detection which offers many benefits over signature-based detection."
"In my opinion, this is the best platform, world-wide, and I am happy with it."
"It is very easy to use, and its usability is great."
"The log correlation is good."
"The interface of this solution is very flexible and easy to use."
"It is stable. We have been using it for some time, without any issues."
"The stability of the RSA NetWitness Endpoint is very good."
"The most valuable feature of RSA NetWitness Network is the single unified dashboard from which you can manage all the different products of RSA. Additionally, the integration with native applications is good."
"I would recommend others to use RSA NetWitness Endpoint at this time because they have evolved from an MD to an EDR solution to an XDR solution."
"ReliaQuest GreyMatter saves around 60% of time or resources."
"ReliaQuest GreyMatter has helped us to reduce security incidents by 89%, which is a significant amount of incidents we have seen."
 

Cons

"Basically, they don't provide customer support tools just to investigate the logs."
"If he is using a smaller company, he can depend on some other tools because Cortex XDR by Palo Alto Networks is a bit expensive."
"Impact on system performance is horrible, adding a lot of delays for users."
"The solution can never really be an on-premises solution based simply on the way it is set up. It needs metadata to run and improve. Having an on-premises solution would cut it off from making improvements."
"A little bit more automation would be nice."
"Cortex XDR by Palo Alto Networks could improve its user interface, which is more complicated compared to competitors such as SentinelOne."
"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."
"I don't see this solution being very scalable."
"The contamination feature could be improved."
"Its price could be improved. It is an expensive product. Its training is also too expensive. It would be great if they can have a better pricing scheme for the training."
"This solution needs an upgrade in reporting. I have heard from RSA that they are working on this, but as of yet it is not available."
"RSA NetWitness Endpoint is a scalable solution. However, the problem which we normally face is in terms of the migration of the solution."
"The solution lacks a reporting engine."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
"NetWitness Endpoint's blocking feature does not work properly - if there's a malicious process, it's not possible to kill it via a custom rule unless and until it's flagged as malicious."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"Very costly product."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"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."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"We are on a three-year contract to use RSA NetWitness Network."
"With RSA, there is flexibility in choosing the service, products, and the range that meets your requirement, as well as they are flexible in terms of pricing."
"It is highly scalable. It can be bought based on your requirements."
"They can easily adjust if you have the requirements which are required. If you have a budget cut or a budget constraint, they can bend."
"The pricing is not very economical. It is a quite costly product for India. One thing is that when you purchase it, you have to purchase a module separately."
"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."
"It is an expensive product."
"The price of the solution depends on the environment. If the environment is large then it will cost more. However, the larger the environment with more endpoints, you will receive an increased discount. If the environment is very small, then you might think it is expensive. It is always better to buy in bulk to receive a discount. The minimum number of assets is usually 500, with discounts on 1000 and 2000."
