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 solution's most valuable feature is the user interface."
"The product's initial setup phase is very easy."
"What I like about Cortex XDR by Palo Alto Networks is that it is a comprehensive solution that contains everything the organization may need when using endpoints."
"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."
"The ability to kind of stitch everything together and see the actual complete picture is very useful. I guess you'd call it a playbook. Some people call it the forensics analysis of what was happening on particular endpoints when they detected some malicious behavior, and what transpired before that to cause that. It is also very user friendly. The way they have done everything and integrated all the solutions that they've purchased over the years to make it a very seamless, effective product is very good. One thing about Palo Alto is that they take the products or services that they purchase and make them seamless for the end user as compared to some companies that purchase other companies and then just kind of have their products off to the side or keep different interfaces. Palo Alto doesn't do that."
"The protection offered by this product is good, as is the endpoint reporting."
"When the pandemic started, Palo Alto came up with many solutions, which helped with the quick shift from on-premises to the cloud."
"Stability is a primary factor, and then there's the ease of distribution and policy management; Cortex XDR by Palo Alto Networks is very easy to work with, and we're quite happy with them."
"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."
"The solution is stable."
"It helps our security team respond more accurately when there are threats, then we get less false positives or negatives."
"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."
"The stability of the RSA NetWitness Endpoint is very good."
"RSA NetWitness does market analysis in a more granular form. It gives you full visibility."
"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."
"The most valuable feature is the way it captures the traffic, and it contains every detail of the communication."
"Zscaler Client Connector has eliminated VPN bottlenecks and outages, improved user productivity with instant secure access, and reduced help desk tickets related to VPN issues, overcoming 60% of VPN-related problems while allowing faster onboarding of remote users and better enforcement of zero-trust security policies."
"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."
"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."
"I'd rate the solution nine out of ten."
"The solution operates in the background seamlessly without the user noticing."
"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."
 

Cons

"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"The MAC agent is not as robust feature-wise as the PC version."
"Whenever the tool releases a new version when deploying the product across the organization, I feel like there are some disturbances in the CPU usage after upgrading the tool to the latest version."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"There is also no recovery feature; if some endpoint is under attack there must be the possibility of recovering it or restoring it to a normal state."
"Cortex XDR could be improved with more GUI features."
"There are some default policies which sometimes affect our applications and cause them to run around."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"I would like to see Security Orchestration and Response Automation (SOAR) integration."
"RSA NetWitness Network could improve on integration with non-native application integration."
"We would like to see the hunting and investigation features of this solution improved, in order to provide better visibility of issues."
"The deployment process is complex. I don't know why, but this solution will suddenly stop working. Logs stop coming. Often, one thing or another stops working. Most of the time, one of my team members is working with troubleshooting and working with technical support. Log passing is also one of the biggest challenge."
"The contamination feature could be improved."
"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 initial setup requires a high level of skill, then the setup is good and smooth."
"The solution doesn't have a reporting engine which would be helpful."
"I rate this product nine out of ten because I have seen some minor instability issues after updates and some room for UI improvement for deeper analytics, with instances of major issues after updating the GCC that required rollbacks."
"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."
"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."
"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."
 

Pricing and Cost Advice

"I feel it is fairly priced."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"The price of the solution is high for the license and in general."
"I don't have any issues with the pricing. We are satisfied with the price."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"NetWitness Endpoint is less costly than its competitors, but it offers fewer features."
"It is an expensive 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."
"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."
"I do not have any opinion on the pricing or licensing of the 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."
