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.

Advanced threat hunting saves significant time in tracking and responding to incidents

Microsoft Defender XDR could be improved with a lower price. My main suggestion would essentially be what Copilot is providing, which is a single pane of glass, so I don't have to go to different windows. That's just a workflow consideration for me. It would be great to have all the information centralized into one particular data app. If I need to open up extra ones, I can, however, I would appreciate a future where everything I need is right there on one single pane of glass. Beyond that, there's really nothing else I see that I would want Microsoft to improve.

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

"The product's initial setup phase is very easy."

"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."

"Cortex XDR can integrate the firewalls and determine the tendencies of the attacks. It's a new generation antivirus, with protection endpoints and detection response. It is very easy to use and everybody can operate the solution."

"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."

"One thing that I like about Cortex XDR by Palo Alto Networks, it is detecting all the suspicious or malicious binaries, and it has integration with Palo Alto Firewall."

"We have a complete overview of all our PCs and it's very easy to handle and to use the interface."

"If you are looking to deploy a security solution as a whole, this is a good option."

"The solution allows us to gain remote access without the user's knowledge and take the necessary actions on the device."

More Cortex XDR by Palo Alto Networks pros

"Microsoft 365 Defender is a good solution and easy to use."

"The integration between all the Defender products is the most valuable feature."

"What I appreciate most about Microsoft Defender XDR is the ability to drill down to the process level, the visibility of processes, and the file-level details of what processes are accessing, including the IP addresses for outbound connections."

"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."

"I like Defender XDR's reports and alerts. They give you updates about the latest hotfixes and zero-day vulnerabilities, which gives me all the information I need to maintain my servers."

"Another noteworthy feature that I find appealing in Microsoft Defender is the credit-backed simulation. This feature enables organizations to train their users on effectively responding to phishing emails through a simulated training environment."

"In Microsoft 365 vendor products, monitoring and connectivity across all Microsoft and third-party connectors enable viewing of all activity within those environments."

"Microsoft Defender is very stable, and you can see that there is a 99.9% success rate when they give us good service."

More Microsoft Defender XDR pros

"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."

"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."

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

"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."

"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."

More Zscaler Client Connector pros

Cons

"Currently, we are monitoring all USB drives and ports but we would like to improve our device control capabilities."

"In an upcoming release, the solution could improve by providing hard disk encryption."

"I would like to see improvement in the tool's user interface, particularly in the area of managing alerts and providing more reporting capabilities."

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

"I think sometimes Cortex XDR agent automatically stops event capturing from the device, and then even the dashboard does not get any notifications from the agent."

"Managing the product should be easier."

"It would be good if they could make an exception for applications. Sometimes, it can be a bit of a challenge to make exceptions for certain applications that have been used as rogue."

"The complexity and confusion regarding product variants, such as XDR, Forexiant, and Forexon, must be addressed."

More Cortex XDR by Palo Alto Networks cons

"The tool gives inconsistent answers and crashes a lot."

"Sometimes, digging into the information and knowing where to go can be difficult. It would be better if much of that information were immediately visible, especially when looking at endpoints or users."

"My client would like the solution to be more customizable without using code. You can only build on the default console, but we're not allowed to change it."

"I personally have not seen much evidence of how Defender can enhance the story of zero trust for enterprises."

"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 interface could be improved. For example, if you want to do a phishing simulation for your employees, it can take a while to figure out what to do. The interface is a bit messy and could be updated. It isn't too bad, but doing some things can be a long process."

"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 console is missing some features that would be helpful for a managed services provider, like device and user management."

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."

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

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

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

"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."

More Zscaler Client Connector cons

Pricing and Cost Advice

"It has reasonable pricing for the use cases it provides to the company."

"Our license will require renewal in August, after which the maintenance will continue as usual."

"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."

"The pricing is a little high. It is per user per year."

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

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

"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."

"Cortex XDR’s pricing is very reasonable."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"It can be complex to navigate since customers have varying licensing agreements across Microsoft. If they go straightforward with E5 for all users, it's simple, but combinations based on budget constraints can complicate things."

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

"Sometimes 365 Defender is expensive, but it can be moderate, depending on the organization's size and the license type. We're satisfied with the cost because it gives us a product that protects our entire environment with DLP. To compromise some cost, of course, we are to complete the most secure environment."

"Microsoft Defender XDR is expensive."

"The bundling of software makes it easier to manage our setup, but Microsoft purposefully obfuscates this through marketing ploys to hide costs."

"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."

"Microsoft Defender XDR is priced high."

"The license cost for a year is approximately forty-four thousand, and this annual saving is a significant factor in our decision to switch."
