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.

Improved threat detection has reduced incidents and has automated investigations with AI
There are multiple features of ReliaQuest GreyMatter which I love personally. The agentic AI, which helps in autonomous investigation and containment, is multiplying the speed of the task to be done. Features such as managed service integration and MDR with human expertise when needed are some major features which I love about ReliaQuest GreyMatter.

Quotes from Members

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

Pros

"Its interface and pricing are most valuable, and it is better than other vendors in terms of security."
"It has absolutely improved the way our organization functions, we are more secure, it is giving us more peace of mind, and it has found malicious activity happening on our endpoints that probably would not have been detected if we didn't have it."
"The protection offered by this product is good, as is the endpoint reporting."
"The initial setup is easy."
"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 integrations are out-of-the-box, as are the playbooks."
"The product has an intuitive dashboard."
"It'll not slow down your system when compared to others."
"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."
"I would highly recommend the solution. Just go ahead and get it."
"The interface of this solution is very flexible and easy to use."
"The stability of the RSA NetWitness Endpoint is very good."
"This solution allows us to locate the malware in real-time."
"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."
"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."
"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

"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."
"This product has not improved my organization - in fact, we are in the process of moving back to another product as a result of Cortex's horrible impact on system performance."
"If you compare it to SentinelOne, which has more functionalities and detection capabilities on an open platform, the pricing on SentinelOne is far more reasonable and cheaper than Cortex XDR by Palo Alto Networks."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"There's an overall lack of features."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"Cortex XDR could be improved with more GUI features."
"Cortex XDR by Palo Alto Networks is a very good product, but financially, it is very expensive, so the company should look into that area."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
"The problem with this product is that it's a bit slow."
"I don't see this solution being very scalable."
"I would like to see Security Orchestration and Response Automation (SOAR) integration."
"The solution lacks a reporting engine."
"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."
"When analyzing something, you have to click several times. It requires a lot of effort to find something."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"Very costly product."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"This is an expensive solution."
"The tool's price is moderate."
"The price was fine."
"The pricing is a little high. It is per user per year."
"Cortex XDR's pricing is ok."
"We are on a three-year contract to use RSA NetWitness Network."
"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."
"It is an expensive product."
"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."
"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 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."
"I do not have any opinion on the pricing or licensing of the product."
