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.

Constant monitoring and analysis boosts network security
There is always room for improvement. I am not giving it a perfect score because I am sure there is something that could be enhanced.Having some sort of certification or training, along with more periodic webinars might be helpful. Having a larger support network would be beneficial. Nobody I know has heard of Lumu, so they are in the same space as Darktrace or CrowdStrike, but people give blank stares. As the community grows for Lumu then that will improve, but that is not really a criticism of Lumu, they simply have not been around that long.

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.

Quotes from Members

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

Pros

"Cortex XDR by Palo Alto Networks's ability to block sophisticated threats in real time is quite good and is on par with SentinelOne's."
"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."
"But overall, when we speak about security and protection, they are one of the top providers."
"The biggest positive impact I see from Cortex XDR by Palo Alto Networks is a significant reduction in the number of people required to manage it."
"From a single pane of glass, you can easily manage all of your endpoints."
"The most valuable feature is that you can select remote access of any machine for sandboxing."
"After installing this solution, it identified, blocked, and provided the complete attack chain, which was very helpful."
"It is a simple platform to use."
"Lumu has allowed us to operate cybersecurity in a better way, with a manageable number of incidents that contain all the context including the Mitre matrix and much more, while providing visibility across on-premise, cloud, remote environments, and IoT such as IP cameras, with automatic mitigation that lets our team focus only on incidents that require our full attention."
"The context provided by the tool is very complete, it includes the miter matrix, playbooks, links, hashes, and much more."
"I like Lumu's simple user interface. When we deployed it, we got full access, allowing us to identify IP addresses on the network and connect machine names to users. It helped us identify and block threats via the firewall. I also appreciate the chat support and ticket closure process. We're currently reviewing network detection solutions, and my recommendations include Lumu, Sentinel, and a few others. Regarding functionality and user-friendliness, I would recommend Lumu over the others."
"The tool's support team helps partners resolve any problems with the product."
"You can access external links, playbooks, MITRE Matrix, and a lot of information."
"With this solution, you don’t need to invest in expensive cybersecurity software because you can operate within the product easily."
"The automated response to incidents works effectively out of the box, and the number of interfaces and platforms it can work with is impressive."
"It's been helpful for overall extended network visibility."
"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."
 

Cons

"Basically, they don't provide customer support tools just to investigate the logs."
"While using Cortex, I noticed some aspects that could be improved, such as increasing the synchronization speed between XDR and Xnor."
"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."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"Additionally, I think the price is very high, and if it can be adjusted, I believe it will be a very good solution."
"The solution lags to the real-time scenarios here and there."
"It'll help if customization was easier."
"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."
"It would be good if we could access the physical logs."
"The free version is minimal compared to the full version."
"The integration with different vendors and endpoints could be improved."
"Nothing so far needs to be improved."
"I am happy with the current features. However, one important one is to improve the reports."
"Lumu's ability to discover threats is an area of concern where improvements are needed."
"Having a larger support network would be beneficial. Nobody I know has heard of Lumu, so they are in the same space as Darktrace or CrowdStrike, but people give blank stares."
"The reports need improvement."
"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."
 

Pricing and Cost Advice

"The price is on the higher side, but it's okay."
"This is an expensive solution."
"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."
"It has a yearly renewal."
"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."
"The tool's price is moderate."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"Compared to Lumu, other solutions are more expensive. SentinelOne was a bit cheaper, and another provider's price structure is unclear, but Lumu fit our budget nicely. SentinelOne's cost depends on the number of devices, and it might be similar to Lumu's, depending on deployment."
"The tool is available at a good price. The tool offers a good and competitive price for customers."
"It is the cheapest solution we found."
"It’s a single license platform."
