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

"But overall, when we speak about security and protection, they are one of the top providers."
"The dashboard is customizable."
"My advice for others looking into using Cortex is that it is very easy to use and very useful for the customer environment, whether it's a public or private one."
"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."
"Cortex XDR is stable, offering high quality and reliable performance."
"The management capabilities, allow an IT organization to get quite a good picture of attempted cyber attacks."
"I like that the product has behavior-based detection which offers many benefits over signature-based detection."
"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."
"The solution is scalable; it creates 3,000 lab logs per second, and I think the solution is suitable for large companies or medium to large companies."
"It's a scalable solution. We have around five to eight customers using RSA NetWitness Endpoint, and we hope to increase the number of users."
"The most valuable feature of RSA NetWitness Network is the single unified dashboard from which you can manage all the different products of RSA, and the integration with native applications is good."
"It is very easy to use, and its usability is great. The use cases are also very easy. The visualizations of the use cases are magnificent. You cannot find this in any other solution. From my point of view, it is great."
"In my opinion, this is the best platform, world-wide, and I am happy with it."
"We've contacted technical support several times. They've been very good. They have been able to help us resolve our issues."
"The interface of this solution is very flexible and easy to use."
"I would highly recommend the solution. Just go ahead and get it."
"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."
 

Cons

"There is a severe gap in functionality between Windows, Linux, and Mac versions."
"There are some false positives. What our guys would have liked is that it would have been easier to manipulate as soon as they found a false positive that they knew was a false positive. How to do so was not obvious. Some people complained about it. The interface, the ESM, is not user-friendly."
"The solution needs better reports. I think they should let the customer go in and customize the reports."
"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."
"The solution should force customers to integrate with network traffic to see the full benefits of XDR."
"The tool needs to be improved in terms of integration and interface."
"The product's pricing needs improvement. They could provide more discounts. Additionally, the dashboard and control panel could be enhanced."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"The problem with this product is that it's a bit slow."
"I don't see this solution being very scalable."
"The initial setup requires a high level of skill, then the setup is good and smooth."
"Its price could be improved. It is an expensive product."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
"The initial setup requires a high level of skill."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"I would like to see Security Orchestration and Response Automation (SOAR) integration."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"Cortex XDR by Palo Alto Networks is an expensive solution."
"The tool's price is moderate."
"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."
"I don't have any issues with the pricing. We are satisfied with the price."
"I don't like that they have different types of licenses."
"The pricing is a little high. It is per user per year."
"The price of the product is not very economical."
"The price is on the higher side, but it's okay."
"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."
"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 an expensive product."
"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."
"We are on a three-year contract to use RSA NetWitness Network."
"I do not have any opinion on the pricing or licensing of the product."
"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."
"It is highly scalable. It can be bought based on your requirements."
