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.

Strong security reporting has supported our consulting work and drives better integration choices
I rated Adlumin Security Operations probably the same as Huntress at eight. They are better at reporting and better integrations. The integrations in terms of the number of integrations you can run from them or connect to are not as many as available with Huntress, but they have easier implementation. Overall, I would say it is the same. I do not want to see any additional features in the next release of Adlumin Security Operations, but I would change the pricing a little bit for around SIEM integrations and SIEM data collection. That is probably the maximum I would do. I do not really have much to say because that is literally five percent of our deployments versus ninety-five percent being Huntress. My overall rating for this review is eight.

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

"We think that this product will help us grow, as it meets our needs currently and we can grow with it over time."
"The level of security I get for my endpoints and servers is extremely valuable."
"The user interface of the solution is sophisticated and straightforward."
"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."
"The product is mostly automated, and we do not have to make decisions, because all the decisions are made by the product itself and we are not required to create any custom policies since the policies that are created are well defined in the product itself."
"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."
"Stability-wise, it is good; I did not hear about any issues in terms of stability, and Cortex XDR by Palo Alto Networks can be trusted completely."
"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."
"We normally focus on Huntress."
"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

"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"There's room for improvement with Mac device installations, which can be challenging."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"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."
"It should support more mobile operating systems. That is one of the cons of their infrastructure right now."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"The onboarding process could be better."
"Adlumin Security Operations's functionality is probably slightly better, but implementation and integration with Office 365 was not as straightforward."
"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 pricing is okay, although direct support can be expensive."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"The tool's price is moderate."
"This is an expensive solution."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"It has a yearly renewal."
"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."
Information not available
"It’s a single license platform."
