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.

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.

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.

Quotes from Members

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

Pros

"They have a new GUI which is just fantastic."
"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."
"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"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 anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."
"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."
"There has been a significant reduction of approximately 70% to 80% in our internal MTTR and MTTD metrics, now around five to eight minutes whereas previously it was hours, which has helped tremendously."
"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."
"Lumu protects against threats immediately and handles them in time."
"The tool's support team helps partners resolve any problems with the product."
"Most of it is automated, so I do not have to watch it to get alerts."
"It's been helpful for overall extended network visibility."
"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 automated response to incidents works effectively out of the box, and the number of interfaces and platforms it can work with is impressive."
"With this solution, you don’t need to invest in expensive cybersecurity software because you can operate within the product easily."
"The context provided by the tool is very complete, it includes the miter matrix, playbooks, links, hashes, and much more."
"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."
 

Cons

"A potential area of improvement for Cortex XDR by Palo Alto Networks is the cost."
"This product has not improved my organization - in fact, we are in the process of moving back to another product as a result of Cortex's horrible impact on system performance."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"The solution lags to the real-time scenarios here and there."
"It takes time to scan the servers and devices."
"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."
"The MAC agent is not as robust feature-wise as the PC version."
"However, if you do not have Palo Alto in your environment, you are paying these additional services just for Cortex XDR by Palo Alto Networks, so it is not a cost-effective solution."
"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."
"It would be good if we could access the physical logs."
"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."
"I am happy with the current features. However, one important one is to improve the reports."
"The reports need improvement."
"Lumu's ability to discover threats is an area of concern where improvements are needed."
"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

"I don't like that they have different types of licenses."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"I don't have any issues with the pricing. We are satisfied with the price."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The solution is expensive. It's pricing is on a yearly-basis."
"I am using the Community edition."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"It is the cheapest solution we found."
"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’s a single license platform."
