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

"Cortex XDR by Palo Alto Networks has changed the way my security team detects, investigates, and responds to threats, as we are able to see the files, unwanted files, unsecured files, and unauthorized files, so we are quarantining them."
"The initial setup isn't too bad."
"The initial setup is pretty easy."
"The user interface of the solution is sophisticated and straightforward."
"Has great threat detection capabilities."
"Cortex XDR is stable, offering high quality and reliable performance."
"I can highlight that we have not faced any security incidents with Cortex XDR by Palo Alto Networks, and even though our environment is quite dynamic, we have not faced any security incident with Cortex XDR by Palo Alto Networks until now."
"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."
"In my opinion, this is the best platform, world-wide, and I am happy with it."
"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."
"We use it for IT security purposes; this is our central log management solution, so we incorporate all of our servers and PCs into this software and can monitor the logs from there."
"The detection rate and tracking features including historical tracking, tracking of the fires on the desk, and tracking of the file last monitored are all quite valuable for us."
"This solution allows us to locate the malware in real-time."
"Ability to isolate the machine when there are malicious files."
"One of the most valuable features is the Orchestrator."
"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

"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."
"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."
"The GUI could be improved."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"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."
"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."
"Fine-tuning the detection policy requires experience because the policy is very complex in Cortex XDR by Palo Alto Networks, and we get high false positive alerts."
"The solution lacks a reporting engine."
"RSA NetWitness Network could improve on integration with non-native application integration."
"When analyzing something, you have to click several times. It requires a lot of effort to find something."
"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."
"The contamination feature could be improved."
"The solution is modular, for example you can buy the RSA ePack, which you buy as a module is not part of the conduit solution. They could include it and have it as an all-in-one solution."
"RSA NetWitness Endpoint is a scalable solution. However, the problem which we normally face is in terms of the migration of the solution."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"Our license will require renewal in August, after which the maintenance will continue as usual."
"The price of the product is not very economical."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"The cost depends on your chosen license type, like Pro or other licenses."
"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."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"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 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."
"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."
"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."
"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."
"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."
