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.

IT Support Admin at Kuehne & Nagel Inc.

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

"Stability is one of the features we like the most."

"The most valuable feature is that you can select remote access of any machine for sandboxing."

"Cortex XDR is a very capable solution for protecting large networks and a lot of endpoints. It's very useful because the automation is very high, and if you combine it with the features on Palo Alto firewalls, it provides very strong protection."

"We have a complete overview of all our PCs and it's very easy to handle and to use the interface. It has a lot of benefits for us."

"I generally believe that Cortex XDR by Palo Alto Networks is probably the best in the market right now."

"The solution's most valuable feature is the user interface."

"Their XDR agent and their behavioral indicators of compromise (BIOC) are pretty nice. Their managed threat hunting is also pretty nice. They also have WildFire, which is a service for actively looking for malware. It's quite useful."

"The policy configuration is great, the granularity of policies that are available is very helpful, it is straightforward to set up, and it has pretty much everything we need and works well within the Palo Alto ecosystem."

More Cortex XDR by Palo Alto Networks pros

"Microsoft Defender XDR is scalable."

"365 Defender saves us a lot of money because we don't have to recover data or hire outside lawyers to help us with legal trouble."

"It's a very scalable tool that can be used in a very small environment or in a very large environment. Everything can be managed from a simple dashboard and can be scaled up or down depending on the customer's environment."

"It saves time for us because we don't need to go through another team or get a separate team involved just for data transfers."

"On the Windows side, Microsoft Defender XDR is definitely integrated into the operating system. Once we have it on the security dashboard, we can see a real-time storyline."

"The unified view of the threat landscape on a central dashboard is the most valuable feature."

"Defender XDR offers richer insights into Defender XDR. It's a better overall experience."

"Based on my experience, I rate Microsoft Defender XDR as nine out of ten."

More Microsoft Defender XDR pros

"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."

"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."

"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."

"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."

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

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

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

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

Cons

"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."

"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."

"Cortex XDR could be improved with more GUI features."

"It is a complex solution to implement."

"The setup is quite easy. We had appropriate support from the manager. One thing that was missing was the integration part."

"Whenever the tool releases a new version when deploying the product across the organization, I feel like there are some disturbances in the CPU usage after upgrading the tool to the latest version."

"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."

"The downside to the solution is that there are a large number of false positives."

More Cortex XDR by Palo Alto Networks cons

"I'd like to see a wider solution that includes not only desktop devices but also other devices, such as servers, storage cabinets, switching equipment, et cetera."

"One of the biggest downsides of Microsoft products, in general, is that the menus are often difficult to find, as they tend to move from place to place between versions."

"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."

"Microsoft frequently changes the names of its products, sometimes even renaming entire portals or features."

"The web filtering solution needs to be improved because currently, it is very simple."

"Automated playbooks and automated dashboards would be preferable to the way the data is currently being presented."

"The design of the user interface could use some work. Sometimes it's hard to find the exact information you need."

"What could be improved in Microsoft 365 Defender is its licensing; it needs to be more consolidated, because there are so many plans for Microsoft 365 Defender, and every other year, there will be new licensing options that become more and more different from each other."

More Microsoft Defender XDR cons

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

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

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

"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."

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

"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."

Pricing and Cost Advice

"The solution is expensive. It's pricing is on a yearly-basis."

"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 did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."

"The cost depends on your chosen license type, like Pro or other licenses."

"The price of the product is not very economical."

"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."

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

"Its pricing is kind of in line with its competitors and everybody else out there."

More Cortex XDR by Palo Alto Networks pricing and cost advice

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

"Microsoft should provide lower-level licensing options. They should do it in such a way that even an individual could purchase a license, and it should be entirely flexible."

"Purchasing Microsoft Defender XDR as part of a Microsoft 365 bundle can be cost-effective, but acquiring it as a standalone product may be more expensive."

"We have a lot of problems in Latin America regarding the price of Microsoft 365 Defender, because the relationship between dollars and the money of the different countries, it's is a lot. Many customers that have small businesses say that they would like the solution but it is too expensive. However, large companies do not find the cost an issue."

"Microsoft Defender XDR is expensive."

"While the standalone price of Defender XDR might seem high, its value becomes clear when considering the ease of implementation and smooth integration with our existing Microsoft infrastructure, especially when bundled with other Microsoft products."

"Microsoft Defender XDR is already included in our Office 365 licensing. It is better because we're saving money by using it."

"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."
