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.

Improved threat detection has transformed our investigation speed and network visibility
In terms of improvement for ExtraHop Reveal(x) 360, I highly suggest, first, that the integration capabilities be further enhanced, perhaps with SIEM and SOAR solutions and firewall management platforms. Second, some of the alert accuracy can be improved and simplified, since there are sometimes false positives. Lastly, dashboard customization could be more flexible, allowing engineers to create role-based dashboards rather than just application-based ones. I would say scalability is another area worth considering for ExtraHop Reveal(x) 360, particularly in large enterprise environments such as ours. As the network grows across data centers, cloud platforms, and distributed infrastructure, the platform needs to scale efficiently without compromising packet capture analytics or detection performance. I would also like to see simpler capacity planning and, if possible, more flexible hardware expansion and improved visibility into appliance resource utilization.

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

"This software helps us understand any issues that may arise when someone is not at work."
"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."
"The product's initial setup phase is very easy."
"Cortex XDR by Palo Alto Networks has changed the way my security team detects, investigates, and responds to threats, as we are able to see the files, unwanted files, unsecured files, and unauthorized files, so we are quarantining them."
"The solution allows us to make investigations. Other XDR solutions also provide similar capabilities but for investigation, Cortex XDR is better."
"The stability of the solution is very good. We have about 100 users on it right now, and we use it twice a week."
"The interface is easy to use and it is more up to date than our previous solution."
"On a scale from one to ten, I would rate Cortex XDR by Palo Alto Networks a nine."
"It stands out for its intuitive and efficient user interface, robust detection capabilities with minimal false positives, and the ability to handle encrypted traffic, making it a valuable asset for network security and management."
"ExtraHop Reveal(x) 360 has positively impacted my organization by helping us detect abnormal activity on our network that we could not detect through our SIEM or XDR platform."
"It is scalable."
"Their technical support is more effective and of better quality than other competitors."
"It is very easy to collect and handle data in ExtraHop Reveal(X) Cloud. Integration with Big Data is also easy. Many of our customers integrate it with Big Data platforms like Splunk or Elastic. It is also easy to handle and easy to understand."
"ExtraHop Reveal(x) 360 has undeniably improved our security posture, reduced manual investigation efforts, and facilitated fast threat detection mechanisms, which all help prevent costly potential breaches in enterprise environments."
"Overall, I would say it is very valuable for real-time network visibility, behavior, and threat detection."
"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

"It is not very strong in terms of endpoint management. It should have additional features like DLP, encryption, or advanced device control. Currently, Cortex is good in terms of the security of the endpoints, but it is not as good as other vendors in terms of the management of the endpoint."
"There is a severe gap in functionality between Windows, Linux, and Mac versions. For example all folder restriction settings are Windows only. Traps 5.0+ does not have SAML / LDAP integration."
"A potential area of improvement for Cortex XDR by Palo Alto Networks is the cost."
"The solution should offer more dashboards and they should be better customized."
"There's room for improvement with Mac device installations, which can be challenging."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"The main issue I could point out is the offline agents and the way that it is missing."
"I would like to see some additional features related to email protection included."
"In terms of improvement for ExtraHop Reveal(x) 360, I highly suggest, first, that the integration capabilities be further enhanced, perhaps with SIEM and SOAR solutions and firewall management platforms."
"There needs to be more support."
"A drawback includes bucket storage limitations for payload data, necessitating timely extraction for thorough investigations."
"One challenge with ExtraHop Reveal(x) 360 is its pricing, which tends to be comparatively high in the marketplace."
"I would like to see ExtraHop Reveal(x) 360 improved by integrating XDR features with NDR."
"They can include integration with SAP. Currently, no vendor provides network performance monitoring in the SAP market. It is a very big market. We have around 400 customers for SAP in Korea. In the USA, there are more than 10,000 customers."
"Their professional service can be improved."
"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."
"Our customers have expressed that the price is high."
"Very costly product."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"I feel it is fairly priced."
"This is an expensive solution."
"Cortex XDR's pricing is ok."
"The price was fine."
"When compared to other solutions, it aligns with the market average, indicating a competitive pricing level."
