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.

Experience improves security management and simplifies threat protection
I have created automated investigations, and while they work, they operate rather slowly in the Microsoft portal. If I automate something, it takes considerable time; if I do it manually, I can complete it in a quarter of the time. The automation response being slow is the main concern; when an incident occurs or if I run a remediation, it takes significant time to complete the remediation. There are some limitations regarding the scalability of Microsoft Defender XDR with specific licensing. For SMB customers, there is only Microsoft Defender for Business, and if they want more features such as XDR features and automation investigation or incident response, they need to purchase Defender for Endpoint. We are currently using the EDR.

A scalable and stable solution with straightforward deployment
We can generate maps from the environment. For example, suppose there is a virus that has a zero-day attack and is publicly unknown. We can block that and keep it away from the network so it is not further replicated. It also has custom white and black lists. We can add a good reputation on both lists and use the sonar technology for Symantec and the online network for advanced reports.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The positive impacts I see from Cortex XDR by Palo Alto Networks include a complete 360-degree view of our security posture altogether, being a uniform platform where we are ingesting logs from multiple resources."
"The one feature of Palo Alto Networks Traps that our organization finds most valuable is the App ID service."
"It has absolutely improved the way our organization functions, we are more secure, it is giving us more peace of mind, and it has found malicious activity happening on our endpoints that probably would not have been detected if we didn't have it."
"The product's most valuable features are massive user and feature intelligence exploit detection."
"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 solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."
"The initial setup isn't too bad."
"The multi-layered approach to the product gives you confidence that it will stop exploits, ransomware, worms, or viruses from compromising endpoints, essentially providing peace of mind."
"The ability to integrate and observe a more cohesive narrative across the products is crucial."
"Within advanced threat hunting, the tables that have already been defined by Microsoft are helpful. In the advanced threat hunting tab, there were different tables, and one of the tables was related to device info, device alert, and device events. That was very helpful. Another feature that I liked but didn't have access to was deep analysis."
"The EDR features are valuable. By getting the EDR features, we have more control over the device. We have information about events in real-time and more protection against zero-day threats and zero-day vulnerabilities. We can monitor every event or action that a device is going through. We can get an idea if it is something malicious or if we have to take any actions."
"The feature I like the most in Microsoft Defender XDR is XDR because it has taken us a while, but we are a global company with people in a few countries, and now we can have centralized alerts that we send out to Teams messages and clean up infected computers or help people in a very short amount of time."
"The Endpoint Manager is incredible; it has a very straightforward interface and is exceedingly easy to use. Pulling out and deploying different tags or resources is a simple task across various departments with different levels of security. The notifications are also simple and satisfying; it's great to see the bubble informing us which devices are compliant and which are waiting to update."
"The most valuable feature is the network security."
"The native capabilities are quite good as it slips in seamlessly as part of our integration and gives a lot of flexibility in terms of configuration and customization as per the business requirements."
"What I like most about the product is its all-in-one solution. With Microsoft Defender XDR, we get coverage for various aspects like endpoint security, cloud security, and image-related cases, all within a single platform. This eliminates the need for multiple products or technical controls to address incidents. The main benefit became evident immediately after deployment, especially in its ability to analyze files and phishing emails quickly. By submitting suspicious files or emails, we receive quick results on whether they are legitimate, suspicious, or malicious, saving time."
"You can advise the solution and protect your environment."
"We can block a virus that has a zero-day attack and is publicly unknown and keep it away from the network so it is not further replicated."
 

Cons

"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"When it comes to core analysis, and security analysis, Cortex needs to provide more information."
"It is a complex solution to implement."
"A little bit more automation would be nice."
"Cortex XDR by Palo Alto Networks could improve its user interface, which is more complicated compared to competitors such as SentinelOne."
"The playbooks could be improved to include more functionalities or actions."
"There are some third-party solutions that are difficult to integrate with, which is something that can be improved."
"The tool gives inconsistent answers and crashes a lot."
"The support team is not competent or responsive."
"My client would like the solution to be more customizable without using code. You can only build on the default console, but we're not allowed to change it."
"We should be able to use the product on devices like Apple, Linux, etc."
"The user interface of Microsoft 365 Defender could improve. They could make it simpler."
"There are other SIEM solutions that are easier to use, mainly based on the creation of rules, use cases, and groups."
"Microsoft Defender is slow to adapt to evolving threats."
"I do think that maybe having a feature within my organization where there are three different domains within which we have to operate would be helpful, as there is currently no unified view within the domains."
"The solution should have better reporting."
 

Pricing and Cost Advice

"It has reasonable pricing for the use cases it provides to the company."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"I am using the Community edition."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"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."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."
"It has consistently offered highly appealing academic pricing, with distinct rates for higher education and general educational purposes."
"It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size."
"Microsoft is not competitive with the pricing of the solution. The competitors are able to offer lower discounts. The price of the solution is higher."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"I would like to have more security features in the lower licenses because not every customer is able to buy E5 licenses. The bundling isn't always easy for our customers to understand. Compared to other tools, it's a good price."
"365 Defender is billed per account. I don't know the exact price, but my supervisor told me that Microsoft Defender is cheaper than the alternatives. It's bundled, so you get all the features in one place."
"The bundling of software makes it easier to manage our setup, but Microsoft purposefully obfuscates this through marketing ploys to hide costs."
"The most valuable licensing option is expensive, so pricing could be improved. Licensing options for this solution also need to be consolidated, because they frequently change."
