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

"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."
"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."
"It is an easy-to-use tool."
"The most valuable features of this product are the management capabilities, which allow an IT organization to get quite a good picture of attempted cyber attacks, and its out-of-the-box investigation capabilities."
"The most valuable feature is that you can select remote access of any machine for sandboxing."
"In one single alert, we are getting the network telemetry, endpoint telemetry, email security telemetry, and proxy telemetry all in one single ticket, making it very easy."
"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."
"If you are looking for security, mainly for advanced threat prevention from ransomware and malware attacks, I would recommend Cortex."
"The all-in-one source for the needs of compliance has put everything into one location without the need of other applications and tools to accomplish the tasks."
"The pricing for this solution with the 3 major components: SIEM, FIM, and vulnerability scanning, can’t be beat."
"Phishing sites were detected and it secured the environment from the upcoming threat."
"AlientVault has helped us in improving our visualization and incident response during cybersecurity situations."
"From my perspective, it saves me about two to seven hours weekly, as now I can easily check in one place all the logs and data in relation to attacks, and it also gives me an overview if a server is not configured properly."
"AlienVault gives us greater visibility into our security and tells us what we need to address."
"The product has been very stable."
"As it includes a logger feature for gathering all logs from all devices (network devices, servers, hosts etc.) it has basically become the only software that we look at when we have a problem."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"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."
"I would like to see some additional features related to email protection included."
"I recommend adding a data loss prevention (DLP) solution to Cortex XDR by Palo Alto Networks. The inclusion of this feature would allow the application of DLP policies alongside antivirus policies via a single agent and console, making it more competitive as other OEMs often offer DLP solutions as part of their antivirus products."
"To jump from the partner to Palo Alto directly was challenging."
"It is an enterprise-level solution. Its price could be less expensive."
"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."
"It'll help if customization was easier."
"The solution should enhance the ADR and reporting."
"More information about what the alerts mean and how they are derived would be useful when determining their significance."
"Scaling, and it has no APIs! It would be hard for any legitimate MSSP to use it."
"The configuration is somewhat complex and the interface a bit non-intuitive."
"I've experienced frequent slowness, and we had to downgrade to filter out many logs."
"The other thing is the agent is OSSEC. They needed to create its own agent to help to find threats on the devices that it happens to be installed."
"This solution could be easier to use. It is hard for some people to understand, and they need to get training and certification just to understand what it's showing them."
"I want to see more compliance management capability. The quality of integrations seems to be a little bit low."
"We have encountered stability issues; we have a high volume of logs passing through our SIEM and the default configuration couldn't handle all the data."
"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

"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"I don't have any issues with the pricing. We are satisfied with the price."
"The price was fine."
"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 pricing is okay, although direct support can be expensive."
"It has reasonable pricing for the use cases it provides to the company."
"Its pricing is kind of in line with its competitors and everybody else out there."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"The licensing fees are dependent on usage."
"The price for this solution is very good, but since the features do not work the price is expensive."
"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."
"I don't know exactly, but I know it is based on the number of logs and the retention duration, such as 30 days or something like that. So, the smallest package is about 500 a month for 30 days of logs. There is a virtual machine. You need resources for it. It is a log collecting VM. They provide the software, and you just have to load a virtual machine. So, you're going to incur some CPU RAM and storage for wherever this log collecting appliance is running, which typically is in our cloud and on our platform for the customer."
"Negotiate the best package for your environment."
"AT&T AlienVault USM is an expensive solution and we pay for the license and the support separately. We paid for the license and support for three years."
"Use an MSSP instead. It is much cheaper."
"It allows you to do a lot with a small price tag... The pricing is the best on the market."
"It’s a single license platform."
