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.

Integrated defenses have unified threat hunting, phishing simulations, and identity investigations
I appreciate Microsoft Defender XDR's MDE, Microsoft Defender tool, which has Attack Simulator. Instead of doing a phishing campaign and getting a separate tool, Microsoft Defender XDR does it all. These features of Microsoft Defender XDR have helped us conduct a phishing campaign quarterly, which has been beneficial. I also appreciate the fact that it has Defender for Office integrated, Defender for Identity, and everything integrated together. I would describe the process of using Microsoft Defender XDR to prioritize incidents in my security operations as quite decent. I appreciate the automatic alerting system where any incidents or alerts we receive come directly to our email. From there, we can open the email, go directly to Microsoft Defender XDR, and start our investigations and remediations. I perceive the integration of security and identity access management in Microsoft Defender XDR as affecting my identity protection strategies very well because it is well integrated with Purview, integrated well with Entra ID, and integrated well with Exchange. I especially appreciate MDO, the Office product. If anything happens and I want to conduct an investigation, it takes me directly to Exchange, where I can also investigate any emails or phishing incidents. Instead of going to different portals, everything can be done from Microsoft Defender XDR. If necessary for further investigation, Microsoft Defender XDR then directs me to that environment. I would assess the integration of AI in guiding security actions within Microsoft Defender XDR as quite positive. Recently, Security Copilot went big, and it is beneficial that I can use that, especially to write KQL. I can do threat hunting features and intelligence all within using Microsoft's Security Copilot. It also has a nice AI feature for threat hunting. I know that all the Defender logs go to Sentinel, and I can pull it up from Microsoft Defender XDR or from Sentinel. The fact that I can actually do all that within Microsoft Defender XDR is a nice feature. In the top module, I can do threat lookups, and I can actually type KQLs in Microsoft Defender XDR and look up incidents. Predictive shielding has had a nice impact on my proactive security measures. It is beneficial that it has, similar to Entra ID, a secure score. For me to improve the product, the secure score helps me out. If I rate it from highest to lowest, I can see what things I can improve. Secure score helps me see what areas I can improve in Microsoft Defender XDR to increase my score and bring it to 80 or more. Knowing Microsoft Defender XDR from using it since 2019, before COVID days, I know that they have improved significantly. It is much more user-friendly and has a very nice vulnerability feature that I find handy and useful. The fact that this feature integrates into Intune is also very decent.

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 initial setup is easy."
"Its ability to react to cyber data attacks is awesome."
"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."
"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."
"The anti-exploit is impenetrable."
"Cortex is a very good total solution on the endpoints."
"I recommend this solution to others because it is easy to manage, reliable, and overall good to use."
"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 biggest return on investment when using Microsoft Defender XDR for me is saving time for the most part."
"Overall, the comprehensiveness of the threat protection is at 95 percent."
"What I appreciate most about Microsoft Defender XDR is the visibility it provides through a breakdown of incidents that come through."
"It has been great for us. Previously, we didn't have a solution to protect us, especially from malware, whereas now, we are getting protection up front, especially from the malware attacks coming through emails or endpoints."
"The threat intelligence is excellent."
"The unified view of the threat landscape on a central dashboard is the most valuable feature."
"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."
"Microsoft Defender XDR's capability to automatically disrupt advanced cyber attacks is very effective."
"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

"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."
"The product's pricing needs improvement. They could provide more discounts. Additionally, the dashboard and control panel could be enhanced."
"The solution lags to the real-time scenarios here and there."
"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."
"It's very time-consuming to log support issues and the people that answer the tickets aren't very knowledgeable."
"The solution could improve by providing better integration with their own products and others."
"Traps doesn't work with McAfee. You need to remove McAfee to install Traps. This is very common, and its nothing that should be an issue. Some antivirus engines recognize Traps as an threat component, so maybe they need to shake hands somewhere."
"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."
"Sometimes, configurations take much longer than expected."
"The data recovery and backup could be improved."
"I do not think the Incident Queue Assistant has helped improve the efficiency of my SOC workflow."
"Some of our older hardware experienced a slight bump in CPU and memory usage. Although I don't have empirical data to back that up, I would suggest possibly more streamlining in the software."
"A simple dashboard without having to use MS Sentinel would be a welcome improvement."
"Their support is bad. They weren't at all able to solve my problems."
"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."
"Troubleshooting in Microsoft 365 Defender can be inefficient."
"The solution should have better reporting."
 

Pricing and Cost Advice

"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"Traps pays for itself within the first 16 months of a three-year subscription. This is attributed to OPEX savings, as security teams spent less time trying to identify and isolate malware for analysis as a result of a reduction in malware incidents, false positives, and breach avoidance."
"It has a yearly renewal."
"This is an expensive solution."
"It is "expensive" and flexible."
"The pricing is okay, although direct support can be expensive."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."
"The license cost for a year is approximately forty-four thousand, and this annual saving is a significant factor in our decision to switch."
"I find the pricing to be quite competitive, especially considering its inclusion in our E5 subscription, which provides a comprehensive set of functionalities."
"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."
"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."
"Microsoft purposely makes its license combinations complex and includes combinations like Microsoft 365 E3 and Microsoft 365 E5, Office 365 E3, Office 365 E5, and Office 365 E1, so you get confused. Microsoft tries to sell you a bundle of a lot of things together."
"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."
"The solution is affordable, and we haven't been hit with any hidden costs. The subscription model is straightforward, and it's easy to understand how much additional features cost. If we need to cancel a license or feature, we do that well in advance to avoid being charged for it, but overall, the pricing and licensing are simple and easy."
"The bundling of software makes it easier to manage our setup, but Microsoft purposefully obfuscates this through marketing ploys to hide costs."
