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 tool is designed to scale for large enterprises and handle large volumes of data."
"Its ability to react to cyber data attacks is awesome. That is pretty much the use of it. What blows your mind is the ability to access your assets remotely and see what is actually going on with them. You can not only see them in a console. You can also react very rapidly to your assets that are compromised."
"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."
"The scalability of Cortex XDR by Palo Alto Networks is very good."
"The most valuable for us is the correlation feature."
"The initial setup is easy."
"The main benefit of using Cortex XDR by Palo Alto Networks while employing Palo Alto Firewall at the internet edge is that it improves security on our endpoint devices, integrating seamlessly with Palo Alto Firewalls to deliver comprehensive network, analyst, and security details all in a single dashboard, which allows us to manage everything from our network devices."
"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."
"Technical support is knowledgeable."
"The most valuable feature is the way it captures the traffic, and it contains every detail of the communication."
"NetWitness Endpoint's most valuable features are its interoperability across many different operating systems and the ease of pivoting from network to endpoint via a single console."
"The log correlation is good."
"In my opinion, this is the best platform, world-wide, and I am happy with it."
"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 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."
"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

"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"The technical support is not very good. I find the process difficult."
"For working with the solution, you only really need a web browser, however, we've found that working on Chrome, for example, is horrible."
"The GUI could be improved. It's a little bit cumbersome. It could be more user-friendly."
"Cortex XDR by Palo Alto Networks can improve mobile integration to allow access to the console."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"Traps doesn't work with McAfee. You need to remove McAfee to install Traps. This is very common, and its nothing that should be an issue. Some antivirus engines recognize Traps as an threat component, so maybe they need to shake hands somewhere."
"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."
"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 integration of the solution needs to be improved. The dashboard needs lots of updates as well. In the next release, we would like to see advanced fraud detection features."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
"When analyzing something, you have to click several times. It requires a lot of effort to find something."
"RSA NetWitness Network could improve on integration with non-native application integration."
"I would like to see Security Orchestration and Response Automation (SOAR) integration."
"The solution lacks a reporting engine."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"This is an expensive solution."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."
"I don't like that they have different types of licenses."
"I am using the Community edition."
"The solution is expensive. It's pricing is on a yearly-basis."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"I do not have any opinion on the pricing or licensing of the product."
"It is an expensive product."
"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."
"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."
"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."
"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."
"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."
