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.

Client activity has been monitored efficiently through in-depth log analysis and traffic filtering
I use the Zscaler speed test, and it is very nice. We use some logs from Zscaler Client Connector to collect data and see what is happening, such as if there is an interruption or something. There is a specific tunnel version that we have to use because, depending on the internet provider, some of them have lower speed, so we have some issues. This is because of the provider, not from Zscaler. We use Office 365 services and Office applications, and because some connections are slow and they do not have full coverage from the internet provider, we have some issues. If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down. This may be because they put some policy. Of course, if you use Office 365 services such as Outlook, the minimum bandwidth is 5 megabits and more, so this causes issues if the users do not have a good remote connection. This depends on the companies and the users, so they need to fix it. This is not from us or our company. It is very useful, and the logs are very helpful. When we go to logs, we understand what is happening.

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 for us is the correlation feature."
"It integrates well into the environment."
"I generally believe that Cortex XDR by Palo Alto Networks is probably the best in the market right now."
"The live terminal is probably the best thing ever. It gives you the access to get straight onto any machine."
"Palo Alto is one of the tech vendors that always provides top-of-the-line products."
"The product has an intuitive dashboard."
"They did what they said, and this solution could apply to any scenario."
"But overall, when we speak about security and protection, they are one of the top providers."
"One of the most valuable features is the Orchestrator."
"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."
"I would highly recommend the solution. Just go ahead and get it."
"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."
"We've contacted technical support several times. They've been very good. They have been able to help us resolve our issues."
"Ability to isolate the machine when there are malicious files."
"They have recently updated the features and the most valuable ones are the instant threat response, ease of use, web interface, integration, and easy access. RSA NetWitness Endpoint is very compatible with other solutions and technologies. However, they do not rely on third-party solutions and have most features built-in."
"We like the solution doesn't have to be managed by an IT department; it's easy to use and you can still check the machine without the IT department being involved."
"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."
"The solution operates in the background seamlessly without the user noticing."
"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."
"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."
"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."
"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."
"I'd rate the solution nine out of ten."
"The real-time analytics feature in Zscaler Client Connector is another valuable feature called Digital Experience, or ZDX, which can easily identify the root cause of issues accessing public or internal resources and provide good analysis so relevant teams can quickly resolve them, making it a very good tool that helps customers."
 

Cons

"Managing the product should be easier."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"A better pricing plan would make this product more competitive."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."
"If they had pulse rate detection, it would be better."
"The solution should offer more dashboards and they should be better customized."
"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."
"I would like to see Security Orchestration and Response Automation (SOAR) integration."
"The solution lacks a reporting engine."
"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."
"The threat intelligence could improve in RSA NetWitness Endpoint."
"The problem with this product is that it's a bit slow."
"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."
"When analyzing something, you have to click several times. It requires a lot of effort to find something."
"The contamination feature could be improved."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."
"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."
"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."
"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."
"Zscaler Client Connector is not low in cost; it is definitely on the higher side."
 

Pricing and Cost Advice

"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."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"I feel it is fairly priced."
"It is "expensive" and flexible."
"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 solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"The tool's price is moderate."
"Very costly product."
"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."
"It is an expensive product."
"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."
"I do not have any opinion on the pricing or licensing of the product."
"The cost depends on the number of endpoints that you want to monitor, but it is not expensive."
"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."
