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.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

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 information the dashboard provides is very clear."
"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."
"Stability is one of the features we like the most."
"From a single pane of glass, you can easily manage all of your endpoints."
"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."
"The most valuable features are the fact that it was running in the background and it would intercept any weird stuff, and the fact that it would send things directly to the cloud for sandboxing. It's quite practical."
"Cortex XDR by Palo Alto Networks is easy to use and does not consume a lot of hardware resources."
"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."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten 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."
"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."
"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."
"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."
"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."
 

Cons

"The product's pricing needs improvement. They could provide more discounts. Additionally, the dashboard and control panel could be enhanced."
"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."
"We had a problem with getting our older endpoints up to date, but their newest updates have been really good. I've been pleased with it in terms of what our needs are. It's doing what we want it to do."
"We would also like to have advanced tech protection and email scanning."
"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."
"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"Additionally, I think the price is very high, and if it can be adjusted, I believe it will be a very good solution."
"Cortex XDR should have a lightweight agent, and the agent size should not be heavy."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."
"Zscaler Client Connector is not low in cost; it is definitely on the higher side."
"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."
"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."
"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 room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."
 

Pricing and Cost Advice

"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."
"Its pricing is kind of in line with its competitors and everybody else out there."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"The cost depends on your chosen license type, like Pro or other licenses."
"This is an expensive solution."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"It is "expensive" and flexible."
"The pricing is a little bit on the expensive side."
"It’s a single license platform."
