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.

Centralized security management has unified risk visibility and enables faster, AI-driven response
Regarding improvements for TrendAI Vision One – Network Security, I think users can take advantage of customized reports. Additionally, clients sometimes find it difficult to integrate third-party open-source integrations, so this area could be improved. Regarding the needed improvements for TrendAI Vision One – Network Security, the deployment guide and migration guide can be better. If clients are migrating, for example, from on-premises to cloud or from one solution to another, the documentation should be more understandable for non-technical teams, helping them decide where to start. I rate it nine out of 10 due to issues with documentation and support for deployment and migration-related activities. Sometimes I find it difficult for clients to understand the requirements for migration. If the guide or documentation is easier, clients can understand it better and decide where to start. In email security with TrendAI Vision One – Network Security, I found one bug related to inbound emails. If we apply attachment policies, such as requiring analysis for incoming email attachments, the AI sometimes flags email signatures as attachments. This issue can lead to quarantining emails without malicious attachments, which is problematic.

Quotes from Members

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

Pros

"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 is a simple platform to use."
"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."
"Has great threat detection capabilities."
"These days it's machine-learning technology and behavior-based analytics features that make us more secure."
"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."
"We have a complete overview of all our PCs and it's very easy to handle and to use the interface. It has a lot of benefits for us."
"One of the things that I enjoy the most is using policy extensions. It's like having host firewalls to control USB connections. I think it's a wonderful tool to restrict use when connecting to our computers. Another important tool is Home Insights. That is an add-on to the Cortex solution. I like that because we can see all the vulnerabilities in the environment and control what assets are connected to our network."
"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 can integrate with almost any cybersecurity tool available in the market."
"Trend Vision One - Network Security has positively impacted my organization as our network operations team has found it very useful for monitoring all threats coming in via the network layer and taking swift actions compared to earlier."
"From the single console, clients can see everything, including each log coming from endpoints, networks, emails, and all attack surface configurations, and they can manage everything from a single dashboard."
 

Cons

"I have faced some issues with Cortex XDR by Palo Alto Networks; there is room for improvement in the sense that certain options prevent us from seeing and segregating data."
"The solution lacks real-time, on-demand antivirus."
"The MAC agent is not as robust feature-wise as the PC version."
"When it comes to malware files, it should be a little quick because, at times, it would give a wrong result in the sense of what it might be on malware, even if it still might be a normal one."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"This is a very costly product."
"The product's pricing could be better."
"Fine-tuning the detection policy requires experience because the policy is very complex in Cortex XDR by Palo Alto Networks, and we get high false positive alerts."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Trend Vision One - Network Security can be improved by integrating with the native firewall and bringing in that telemetry feed."
"In email security with TrendAI Vision One – Network Security, I found one bug related to inbound emails. If we apply attachment policies, such as requiring analysis for incoming email attachments, the AI sometimes flags email signatures as attachments."
 

Pricing and Cost Advice

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"I don't recall what the cost was, but it wasn't really that expensive."
"Cortex XDR's pricing is ok."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"It has reasonable pricing for the use cases it provides to the company."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The price was fine."
"It’s a single license platform."
