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.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

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 multi-layered approach to the product gives you confidence that it will stop exploits, ransomware, worms, or viruses from compromising endpoints, essentially providing peace of mind."
"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."
"This software helps us understand any issues that may arise when someone is not at work."
"Based on my experience with Cortex XDR by Palo Alto Networks, I highly recommend it due to its quick response to zero-day attacks and low utilization from end-user devices."
"When the pandemic started, Palo Alto came up with many solutions, which helped with the quick shift from on-premises to the cloud."
"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."
"It collects and caches and the knowledge of machine learning from different customers to take to the cloud, it makes it better to use for everybody, it allows for quick learning and updates and can, therefore, offer zero-day malware security, and this sharing of metadata helps make the solution very safe."
"The level of security I get for my endpoints and servers is extremely valuable."
"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."
"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."
"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."
"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."
"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 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 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

"It's more focused on network communication. If a customer wants to increase the level of protection and start working with documents, it's impossible to integrate these features into the system. It's more of a communication-oriented system than a content security-oriented system."
"When it comes to core analysis, and security analysis, Cortex needs to provide more information."
"Every 30 or 40 days, there's a new version and we need to go and make sure our customer's laptops are upgraded."
"As an improvement, I would like to see enhanced connection speeds."
"The solution could improve by providing better integration with their own products and others."
"The only issues that we have are, one the cost, two the dashboard is not very intuitive, even though you can drill down within the dashboard, we usually have to gather information from other sources to determine locations and if its a false positive."
"It's not an ideal choice for smaller businesses, as you need a minimum of 200 endpoints to even use the solution at all."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"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."
"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."
"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."
"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."
"Zscaler Client Connector is not low in cost; it is definitely on the higher side."
 

Pricing and Cost Advice

"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."
"It's about $55 per license on a yearly basis."
"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."
"It has reasonable pricing for the use cases it provides to the company."
"I am using the Community edition."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"It’s a single license platform."
