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.

Cloud-native threat detection has improved incident investigations and now reduces breach risk
We have covered most of the features over the past three years and look forward to discovering more as we work closely with the ExtraHop technical team, who are open to sharing what they have developed. Pricing is on the higher side, typically based on load, volume of traffic, and deployment scale. The advanced detection capabilities provide significant value in reducing investigation time, making the licensing and pricing acceptable for larger organizations. 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. ExtraHop Reveal(x) 360's SaaS environment is well-suited for cloud, on-premises, and hybrid environments, effectively addressing real-life scenarios involving east-west and north-south traffic. The platform is recommended for large organizations in need of comprehensive detection capabilities. I would rate this product overall as an 8 out of 10.

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

"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."

"Their technical support is more effective and of better quality than other competitors."
"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."

"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"In general, the price could be more competitive."
"It is an enterprise-level solution. Its price could be less expensive."
"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"The negative aspect I see is the economic model used by Palo Alto."
"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."
"The technical support is not very good. I find the process difficult."
"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."
"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."
"I would like to see ExtraHop Reveal(x) 360 improved by integrating XDR features with NDR."
"Their professional service can be improved."
"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."
"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."
 

Pricing and Cost Advice

"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"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."
"Its pricing is kind of in line with its competitors and everybody else out there."
"Cortex XDR's pricing is ok."
"The solution is expensive. It's pricing is on a yearly-basis."
"It has reasonable pricing for the use cases it provides to the company."
"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"It is "expensive" and flexible."
"When compared to other solutions, it aligns with the market average, indicating a competitive pricing level."
"It’s a single license platform."
