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.

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

"What I like about Cortex XDR by Palo Alto Networks is that it is a comprehensive solution that contains everything the organization may need when using endpoints."
"The most valuable features are incident creation, policy-based protection, IP whitelisting, and device encryption. These are beneficial for endpoint and server security."
"Palo Alto is one of the tech vendors that always provides top-of-the-line products."
"Palo Alto is constantly adding new features."
"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."
"We can use Cortex XDR to get the entire graph of the incidents from source to destination, and we can take remedial action."
"Traps has drastically reduced our endpoint attack surface via advanced detection capabilities, sandboxing of never before seen programs, and by drastically limiting where executables can launch in the first place."
"The good thing about the product is that it's always scanning."
"I'm glad we purchased it, wished we would have gone with outside monitoring instead of inhouse and there is a lot to learn; great product though."
"AlienVault's "Overview" dashboard makes it very easy to see everything going on in your network that needs your immediate attention."
"The most useful feature is the customization for alarms, alerts, and reports."
"The asset discovery and inventory capabilities in USM Anywhere is quite good."
"AlienVault's reporting is good. I like that vulnerability assessment is part of the solution, and the UI is intuitive. Also, the overhead is low, which is to say we don't need a dedicated SOC team to manage and analyze things constantly. We're a small company that doesn't have those resources."
"Previous to this, we really didn't have any protection, any intrusion system in place, and it's made me more comfortable, since I'm in charge of IT for this company, because I sleep better at night."
"Monitoring customer's critical network is now almost a one man job."
"AlienVault has allowed us to help our customers satisfy compliance needs around logging and monitoring (HIPAA, PCI, etc.) and has also provided a comprehensive platform that goes beyond just being a SIEM."
"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

"This is a very costly product."
"Previously, the endpoint would leave the environment, not being on our VPN, essentially unable to interact with the server to upload files. It was unable to retrieve new file verdicts. It was using a thing called "local analysis" to determine if something was a malicious file or not. There was no dynamic analysis."
"The main issue I could point out is the offline agents and the way that it is missing."
"There are some false positives. What our guys would have liked is that it would have been easier to manipulate as soon as they found a false positive that they knew was a false positive. How to do so was not obvious. Some people complained about it. The interface, the ESM, is not user-friendly."
"Limited remote connection."
"There are some limitations on the Traps agents."
"Cortex XDR by Palo Alto Networks can improve mobile integration to allow access to the console."
"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."
"Customer service is 4/10 - they need to provide faster responses to emails."
"They should improve the reporting capabilities. Different functions to customize reports should be added."
"I had a renegade plugin that was installed by the company who helped me with the initial setup. The plugin was missing a command to rotate logs and would fill my hard drives capacity to full quickly."
"Support can be slow at times, but the quality is high. Posted knowledge base articles could use improvement."
"For creating new rules, you have to be familiar with regular expressions. I feel there could be something built-in to make sure that process is easier."
"More information about what the alerts mean and how they are derived would be useful when determining their significance."
"User friendly interface could be an advantage. Sometimes we may face trouble when we were going through the settings of AlienVault SIEM."
"The log query capability is pretty restrictive and I find myself searching through raw logs via command line more often than the GUI."
"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 recall what the cost was, but it wasn't really that expensive."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"The pricing is a little high. It is per user per year."
"I don't have any issues with the pricing. We are satisfied with the price."
"It is "expensive" and flexible."
"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."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"It has reasonable pricing for the use cases it provides to the company."
"I don't think the product's pricing is a good value because they try to raise the price 50 percent every year... AlienVault needs to understand that not all customers are huge enterprises... Their sales team is way too aggressive. The price they advertise is not always the price you get."
"The licensing fees are dependent on usage."
"AlienVault is flexible on their pricing for unlimited licenses."
"It's affordable for most customers."
"Its price is in the medium to upper range."
"So far, I feel the product's pricing is a good value. The technology is decent. You get what you pay for. I think it's fair."
"QRadar, ArcSight and Splunk are some of the most expensive SIEM products out there in the market and not everyone has the budget to buy them. In such cases, AV USM is a very cost effective alternative."
"We ran a few PoCs. The price and feature set were the best with AlienVault."
"It’s a single license platform."
