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

"We use it for malicious connections from malicious websites, to identify payloads that might be inside the traffic, to identify malicious processes or bugs that are running on the network, and any activities that tend to lead to data infiltration."

"The behavior-based detection feature is valuable."

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

"Cortex XDR by Palo Alto Networks saves time in various ways, although the user interface is fairly standard."

"From a single pane of glass, you can easily manage all of your endpoints."

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

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

"From the Palo Alto side, whatever they buy, they integrate that really well into their integration suite, and that makes a massive difference."

More Cortex XDR by Palo Alto Networks pros

"I like 365 Defender's advanced threat hunting. The dashboard is user-friendly with templates for site policies, etc. The most important use case is evaluating the risk links and applications."

"The product is very easy to use."

"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."

"The best feature is probably the alert generation. When I do a security reset, the other session triggers instantly from the Defender console, and I can work on it. The policies are three times, but they are also ready to install it."

"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."

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

"The solution is well integrated with applications. It is easy to maintain and administer."

"The feature of Microsoft Defender XDR that I preferred the most traditionally was its focus on endpoint protection, but now identity is right up there with endpoint security. Identity is important because different compromises start at the identity level. This allows us to understand what actions are being taken, who is doing them, and whether it is actually them."

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."

"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."

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

"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."

"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."

"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."

Cons

"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."

"Basically, they don't provide customer support tools just to investigate the logs."

"There is also no recovery feature; if some endpoint is under attack there must be the possibility of recovering it or restoring it to a normal state."

"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."

"The solution could improve by providing better integration with their own products and others."

"The server sometimes stops continuously to check things so it would be helpful to receive access updates or technical reasons."

"Currently, if you use Palo Alto endpoint protection as the only solution it's very complicated to remove pre-existing threats."

"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."

More Cortex XDR by Palo Alto Networks cons

"There could be a way to proactively monitor unusual activity ."

"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."

"The management and automation of the cloud apps have room for improvement."

"Microsoft Defender XDR is not a full-fledged EDR or XDR."

"Improving scalability, especially for very large tenants, could be beneficial for Microsoft Defender XDR."

"Sometimes, configurations take much longer than expected."

"Their response time is okay, it works fine, but the time it takes to resolve escalated cases needs improvement."

"There's still some more work to be done there. Additionally, the limited terminal live access an analyst has is very restricted."

More Microsoft Defender XDR cons

"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."

"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."

"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 pricing is a little bit on the expensive side."

"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."

"This is an expensive solution."

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

"It has a higher cost than other solutions, like CrowdStrike or Microsoft’s EDR tools, but it reduces the cost of our operations because it’s a new generation antivirus tool."

"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."

"Every customer has to pay for a license because it doesn't work with what you get from a managed services provider."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"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 is not competitive with the pricing of the solution. The competitors are able to offer lower discounts. The price of the solution is higher."

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

"The price could be better. Normally, the costs depend on the country you're located in for the license. When we were in the initial stage, we went with the E5 license they call premium standard. It cost us around $5.20 per month for four users."

"On average, we pay around 55 euros per user for the services and features we receive."

"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 solutions price is fair for what they offer."

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