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

"Cortex is a very good total solution on the endpoints."
"The solution's most valuable feature is the user interface."
"I recommend this solution to others because it is easy to manage, reliable, and overall good to use."
"Palo Alto is one of the tech vendors that always provides top-of-the-line products."
"It'll not slow down your system when compared to others."
"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."
"The solution allows control over the user and his machine through Cortex XDR security policies."
"I have found the solution to be very easy in respect of the integration and configurable."
"The email protection feature is the most valuable because our risks primarily lie there, and it seems to be the most popular target."
"The most valuable feature depends on the scenario. For compliance, I like Microsoft Purview Information Protection and Data Loss Prevention. Sentinel is the most helpful feature for security. 365 Defender helps us prioritize threats across an enterprise. It's a crucial feature for the managed services team."
"The unified view of the threat landscape on a central dashboard is the most valuable feature."
"I like how Microsoft XDR and the other Microsoft products are integrated into a single unified security stack covering identity access management, endpoint protection, email, cloud applications, etc."
"Overall, the solution has decreased our time to detect and respond."
"The comprehensiveness of Microsoft's threat detection is good."
"Based on my experience, I rate Microsoft Defender XDR as nine out of ten."
"Overall, the comprehensiveness of the threat protection is at 95 percent."
"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."
"You can advise the solution and protect your environment."
 

Cons

"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."
"There are some limitations on the Traps agents."
"It is not very strong in terms of endpoint management. It should have additional features like DLP, encryption, or advanced device control. Currently, Cortex is good in terms of the security of the endpoints, but it is not as good as other vendors in terms of the management of the endpoint."
"To jump from the partner to Palo Alto directly was challenging."
"The setup is quite easy. We had appropriate support from the manager. One thing that was missing was the integration part."
"There are some default policies which sometimes affect our applications and cause them to run around."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"It would be beneficial to have a more seamless experience with everything consolidated in one place, particularly when dealing with aspects related to the Exchange console."
"The dashboards could be improved."
"The licensing process needs improvement and clarification, as it is currently difficult to understand which features are licensed to which users."
"While the XDR platform offers valuable functionalities, it falls short of other solutions in its ability to deliver a cohesive identity experience."
"Their support is bad. They weren't at all able to solve my problems."
"What could be improved in Microsoft 365 Defender is its licensing, e.g. it should be more consolidated and would be good if it has some optimizations. Improving the alerts and notifications, in terms of adding more details, would also be good for this solution."
"Defender's AI for identifying suspicious activity could be improved. Also, I do a lot of home updates. Maybe there is a way to set it up faster. For example, let's say that I want to automatically update seven computers, servers, etc. I wouldn't do it to a user, but maybe the server. I don't mind if the server restarts automatically."
"Every now and then, Microsoft Defender XDR seems to go through and aggregates almost a week's worth of incidents and wraps them up, indicating a huge problem."
"The solution should have better reporting."
 

Pricing and Cost Advice

"The tool's price is moderate."
"The pricing is a little bit on the expensive side."
"Our customers have expressed that the price is high."
"The pricing is okay, although direct support can be expensive."
"This is an expensive solution."
"The price was fine."
"The price is on the higher side, but it's okay."
"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."
"Licensing is somewhat confusing, particularly when presenting our pitch decks to stakeholders and leveraging key features in premium SKUs, but we managed with some assistance from Microsoft."
"Microsoft Defender XDR's licensing is complicated."
"I find the pricing to be quite competitive, especially considering its inclusion in our E5 subscription, which provides a comprehensive set of functionalities."
"The price of the solution is high compared to others and we have lost some customers because of it."
"For Defender, they have Endpoint Plan 1 and Endpoint Plan 2, but I don't know on what basis they have classified Endpoint Plan 1 and Plan 2, but it has given me enough pain to pick and design Endpoint Plan 1 or Endpoint Plan 2 for my organization. In fact, we are still struggling with it. Too many SKUs are confusing. There should not be too many SKUs, and they shouldn't charge for every new feature."
"Understanding the subscription model has been a bit challenging, as every feature or requirement comes with an additional cost."
"Defender plan 1 is tenant-wise, and Defender plan 2 is per-user, which makes it more expensive. To have certain features, you would need to purchase the E5 license. For all of the capabilities that the tool provides, the price, though it can be high, is fair."
"The solutions price is fair for what they offer."
