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.

Client activity has been monitored efficiently through in-depth log analysis and traffic filtering

I use the Zscaler speed test, and it is very nice. We use some logs from Zscaler Client Connector to collect data and see what is happening, such as if there is an interruption or something. There is a specific tunnel version that we have to use because, depending on the internet provider, some of them have lower speed, so we have some issues. This is because of the provider, not from Zscaler. We use Office 365 services and Office applications, and because some connections are slow and they do not have full coverage from the internet provider, we have some issues. If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down. This may be because they put some policy. Of course, if you use Office 365 services such as Outlook, the minimum bandwidth is 5 megabits and more, so this causes issues if the users do not have a good remote connection. This depends on the companies and the users, so they need to fix it. This is not from us or our company. It is very useful, and the logs are very helpful. When we go to logs, we understand what is happening.

Quotes from Members

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

Pros

"Cortex covers everything I need. It's a perfect solution. Cortex provides a different level of visibility because it's an extended EDR, allowing you to grab logs from the network and firewalls. Palo Alto invented the concept of the extended EDR or XDR."

"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."

"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."

"They did what they said, and this solution could apply to any scenario."

"The one feature of Palo Alto Networks Traps that our organization finds most valuable is the App ID service."

"Traps pays for itself within the first 16 months of a three-year subscription."

"Palo Alto is constantly adding new features."

"It has pretty much everything we need and works well within the Palo Alto ecosystem."

More Cortex XDR by Palo Alto Networks pros

"We are able to consolidate licences and make use of many Microsoft products using this solution, and if we have any Microsoft customers, we encourage them to use this solution for enterprise defence."

"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."

"Overall, the comprehensiveness of the threat protection is at 95 percent."

"The comprehensiveness of Microsoft's threat detection is good."

"Email protection is the most valuable feature of Microsoft Defender XDR."

"The product integrates security into one tool instead of having third-party security tools."

"The most valuable feature is the network security."

"Vulnerability assessment and just-in-time access are some valuable features of Defender for server plans."

More Microsoft Defender XDR pros

"I'd rate the solution nine out of ten."

"The best features of Zscaler Client Connector are that it gives the client a much more transparent experience, as they don't have to worry about connecting to a VPN."

"Zscaler Client Connector is quite scalable, and I would rate its scalability as nine or ten out of ten."

"It is very useful, and the logs are very helpful; when we go to logs, we understand what is happening."

"It is very important to see what is happening between the user and the applications that we have, and to filter the traffic from outbound traffic and inside traffic."

"The solution operates in the background seamlessly without the user noticing."

"The real-time analytics feature in Zscaler Client Connector is another valuable feature called Digital Experience, or ZDX, which can easily identify the root cause of issues accessing public or internal resources and provide good analysis so relevant teams can quickly resolve them, making it a very good tool that helps customers."

"Zscaler Client Connector has eliminated VPN bottlenecks and outages, improved user productivity with instant secure access, and reduced help desk tickets related to VPN issues, overcoming 60% of VPN-related problems while allowing faster onboarding of remote users and better enforcement of zero-trust security policies."

Cons

"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."

"The connection to the internet has not performed as expected."

"There are some limitations on the Traps agents."

"I would rate it an 8 rather than a 10 mainly because there is still room to improve the user experience around complex investigations, including alert tuning and third-party integration."

"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."

"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."

"One thing that was missing was the integration part. Currently, they don't have out-of-box integration with IBM QRadar, or if they have the integration, the integration doesn't work well."

"I am facing issues with customer support for Cortex XDR by Palo Alto Networks, so I am not satisfied with customer support."

More Cortex XDR by Palo Alto Networks cons

"These days, in the security industry, there is a buzzword called zero trust. I personally have not seen much evidence of how Defender can enhance the story of Zero Trust for enterprises."

"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."

"I haven't really come across the incident Q assistant helping improve the efficiency of my SOC workflow."

"The documentation on their website is somewhat outdated and doesn't show properly. I wanted to try a query in Microsoft Defender 365. When I opened the related documentation from the security blog on the Microsoft website, the figures were not showing. It was difficult to understand the article without having the figures. The figures were there in the article, but they were not getting loaded, which made the article obsolete."

"The capability to not only thwart attacks but also to adapt to evolving threats is crucial."

"The support team is not competent or responsive."

"The dashboard should be easier to use. There is also improvement needed in the reporting when it comes to exporting or scheduling reports."

"When discussing the secure score, which includes overviews and recommended actions, some of these recommended actions are not applicable to us, particularly those related to Microsoft Internet Explorer, which we do not use in any of our environments."

More Microsoft Defender XDR cons

"Zscaler Client Connector is not low in cost; it is definitely on the higher side."

"There is a hard learning curve for Zscaler Client Connector; their support isn't the greatest all the time."

"There is room for improvement regarding the price of Zscaler Client Connector, as it is one of the most expensive solutions available."

"The stability of Zscaler Client Connector needs improvement, as it often disconnects and reconnects."

"I rate this product nine out of ten because I have seen some minor instability issues after updates and some room for UI improvement for deeper analytics, with instances of major issues after updating the GCC that required rollbacks."

"If the speed is slow for Zscaler Client Connector connection, then we have issues because if the speed is not good, then Zscaler Client Connector goes down."

Pricing and Cost Advice

"It is present, but when compared to other competitive products, I would say it is not less expensive; however, when all of the other added values are considered, the price is reasonable."

"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."

"The pricing is okay, although direct support can be expensive."

"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."

"Cortex XDR by Palo Alto Networks is quite an expensive solution."

"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."

"I don't like that they have different types of licenses."

"The price of the solution is high for the license and in general."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"All I can say again is the E5 gives you all the capabilities that it offers. It also gives Office 365 and one terabyte of storage. All in all, the E5 license model makes sense. There are some people who say it's quite costly, but rather than paying different vendors, it makes sense to go all in with Microsoft if you've got that licensing. From that perspective, it's cost-effective, but I can't comment much on that."

"365 Defender can get expensive because you pay per gigabyte of data ingested. On the other hand, much of the data available in the other Microsoft security solutions are made available relatively cheaply—sometimes at cost or for free. Integrating only a limited set of third-party solutions with Sentinel would be cost-effective. It's much more affordable if companies only have Microsoft stuff."

"The solutions price is fair for what they offer."

"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."

"Defender XDR is included in the E5 license, but it's a bit too expensive."

"I find the pricing to be quite competitive, especially considering its inclusion in our E5 subscription, which provides a comprehensive set of functionalities."

"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."

"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."
