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.

Provides detailed event investigation and endpoint control but needs better Mac support and UI improvements
I find the advanced behavioral analytics feature in Bitdefender GravityZone EDR a little gimmicky, as I don't usually find much use for it. The advanced behavioral analytics feature needs to be optimized to be more user-friendly and easier to work with. We don't specifically look for the customizable dashboards within Bitdefender GravityZone EDR; rather, we get the logs on our SIEM solution, QRadar, where we have created the dashboards. We also have Tableau and Power BI, so we don't utilize any dashboards on the EDR front. I would like to optimize the incident response area as well, especially when comparing my experience with CrowdStrike, which is relatively more responsive and easier to navigate when there are multiple hosts involved. Other areas of improvement for Bitdefender GravityZone EDR include its lack of support for Mac devices.

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

"The most valuable features are the fact that it was running in the background and it would intercept any weird stuff, and the fact that it would send things directly to the cloud for sandboxing. It's quite practical."
"I like that the product has behavior-based detection which offers many benefits over signature-based detection."
"One of the things that I enjoy the most is using policy extensions. It's like having host firewalls to control USB connections. I think it's a wonderful tool to restrict use when connecting to our computers. Another important tool is Home Insights. That is an add-on to the Cortex solution. I like that because we can see all the vulnerabilities in the environment and control what assets are connected to our network."
"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."
"My advice for others looking into using Cortex is that it is very easy to use and very useful for the customer environment, whether it's a public or private one."
"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"We use it for malicious connections from malicious websites, to identify payloads that might be inside the traffic, to identify malicious processes or bugs that are running on the network, and any activities that tend to lead to data infiltration."
"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"I never had any issues, never had any bugs, it was very stable."
"It is one of the best and well-featured solutions at the moment, and I recommend it."
"It's very easy to set up, it's simple to deploy and you can really control every aspect."
"It's easy to deploy."
"It is a usable program that works."
"It has the ability to remotely control user PCs and execute specific commands to ensure their security. However, this capability could also pose some concerns."
"The cloud management is easy and useful, especially in our case when we have multiple offices in different locations."
"Bitdefender has improved my organization in the way that it has grown our revenue over the years, with more clients signing on Bitdefender GravityZone and migrating from other antivirus solutions because of the ease of use, ease of installation, and the fact that it can be deployed in the cloud while the same software can actually be installed on other servers or workstations and automatically knows what it's protecting."
"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's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"We had a problem with getting our older endpoints up to date, but their newest updates have been really good. I've been pleased with it in terms of what our needs are. It's doing what we want it to do."
"On the pricing aspect, Cortex XDR by Palo Alto Networks needs to have a more reasonable rate, particularly for customers in Sri Lanka and Asian countries."
"The technical support is not very good. I find the process difficult."
"If you compare it to SentinelOne, which has more functionalities and detection capabilities on an open platform, the pricing on SentinelOne is far more reasonable and cheaper than Cortex XDR by Palo Alto Networks."
"Currently, we are monitoring all USB drives and ports but we would like to improve our device control capabilities."
"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."
"Based on our experience so far, its implementation is quite complex."
"The firewall security could be better."
"We would like to see a more advanced dashboard."
"From my experience, Bitdefender GravityZone EDR consumes a lot of resources over time; although not initially, we have noticed that some machines use significant memory just to keep Bitdefender GravityZone EDR functions operational."
"Unfortunately, the solution wasn't designed to be used in France."
"Policy customization and deployment need a little bit of improvement. The push policies, the first line, and all those things."
"I would like to optimize the incident response area as well, especially when comparing my experience with CrowdStrike, which is relatively more responsive and easier to navigate when there are multiple hosts involved."
"This solution would be improved if it included antivirus functionality. You currently need to install a plug-in to Outlook for each email to be scanned."
"In terms of improvement of the solution, it could have better features. For example, having a firewall within. This way we would only need one solution."
"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 like that they have different types of licenses."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"Cortex XDR's pricing is ok."
"The price of the product is not very economical."
"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."
"Our customers have expressed that the price is high."
"The cost depends on your chosen license type, like Pro or other licenses."
"Cortex XDR’s pricing is very reasonable."
"The solution's pricing is average."
"We need to pay for a yearly license for the solution."
"The solution's price is mid-ranged."
"There are some differences. It's more cost-effective, yet it provides the same functionalities as Defender. That's why I've been exploring the comparisons. We pay for it annually, and it's a per-seat payment."
"I rate the product's price a four on a scale of one to ten, where one is low, and ten is high."
"The product has a reasonable price."
"It has a suitable price for every company and organization."
"If you look at the solution's price point, it's actually low market value, especially in comparison to other ones."
"It’s a single license platform."
