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

"Automation and playbooks have helped me significantly, as Cortex Xnor's playbooks predefine the workflow of the automation, such as response processes, alert triggering, and enriching the context, efficiently detecting and blocking malicious attacks with firewalls while eliminating workload and speeding responses for next-generation operations."

"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."

"It is easy to use."

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

"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."

"Palo Alto is constantly adding new features."

"Overall, it's a great platform; it integrates very well with other solutions from Palo Alto and also with our vendors, the ease of use is excellent, I love the root cause analysis from Cortex, which is amazing, and in a few clicks you can have the full root cause."

"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."

More Cortex XDR by Palo Alto Networks pros

"Microsoft Defender XDR provides strong identity protection with comprehensive insights into risky user behavior and potential indicators of compromise."

"Microsoft 365 Defender's most valuable feature is the ability to control the shadow IP."

"We also use Microsoft Sentinel, Defender for Cloud, Defender for Identity, and Microsoft Defender for Cloud Apps. They are all integrated and it was very easy to integrate them. In my experience with the integrations, it was just a click of a button and things were integrated. It's just a button."

"Among the most valuable features are the alert timeline, the alert story, which is pretty detailed. It gives us complete insight into what exactly happened on the endpoint. It doesn't just say, "Malware detected." It tells us what caused that malware to be detected and how it was detected. It gives us a complete timeline from beginning to end."

"We use Microsoft 365 Defender to help secure threats of the Office package, such as Word, Excel, and PowerPoint, and additionally, it can fix issues."

"I like the easy integration and advanced possibilities. We can implement it at customer sites in a few clicks, but we can also dive deep and drill down to extended features. There's a very good starting point to get into this product and all the features from Defender."

"Instead of an hour, it takes five or 10 minutes now; it's a lifesaver for me and keeps my clients from being threatened and attacked every day."

"The proactive remediation aspects and the surfacing of suspicious activity for investigation and escalation are the key aspects we appreciate most."

More Microsoft Defender XDR pros

"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."

"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."

"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."

"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

"A potential area of improvement for Cortex XDR by Palo Alto Networks is the cost."

"There are some default policies which sometimes affect our applications and cause them to run around. In the hotel industry, we use a different type of data versus Oracle and SQL. By default, there are some policies which stop us from running properly. Because of this, the support level is also not that strong. We have to wait to get a results."

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

"Cortex XDR by Palo Alto Networks could improve its user interface, which is more complicated compared to competitors such as SentinelOne."

"Cortex XDR is trickier to configure than other Palo Alto products. This is one area where we are not so satisfied."

"The solution lacks real-time, on-demand antivirus."

"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."

"They are charging for Network Traffic Analyzer (NTA) services, so if the per GB data could be provided at a certain level free of cost or at the same cost which the customer is taking for the entire bundle, that would be better."

More Cortex XDR by Palo Alto Networks cons

"The message trace feature for investigating mail flow issues should add more detailed information to the summary report... if they could extend the summary report a little bit, make it more descriptive, ordinary administrators could understand what happened and that the emails failed at this or that point. That way they would know the location to go to try to correct it and to prevent it from occurring again."

"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."

"The user interface of Microsoft 365 Defender could improve. They could make it simpler."

"We struggle sometimes with tier one support agents who give canned responses."

"The improvements to Microsoft Defender XDR would probably go on the Linux side. There's still some more work to be done there."

"The licensing is a nightmare and has room for improvement."

"The solution does not offer a unified response and standard data."

"The patching capability should be there. Patching is something that you cannot do even though you see the vulnerabilities present in your environment. For patching, you have to depend on another solution."

More Microsoft Defender XDR cons

"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."

"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."

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

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

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

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

Pricing and Cost Advice

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

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."

"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."

"Compared to CrowdStrike, Cortex XDR is an expensive solution."

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

"I feel it is fairly priced."

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

More Cortex XDR by Palo Alto Networks pricing and cost advice

"Microsoft 365 Defender offers competitive pricing."

"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."

"I believe the pricing is fair and acceptable. I consider it to be reasonable and satisfactory."

"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."

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

"Understanding the subscription model has been a bit challenging, as every feature or requirement comes with an additional cost."

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

"It is fairly priced because we get complete integrated services with the E5 license."
