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.

Quotes from Members

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

Pros

"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."

"If any application performs suspicious activities, such as changing registries or modifying other applications, Cortex XDR detects and blocks the entire application."

"The scalability of Cortex XDR by Palo Alto Networks is very good."

"The most valuable feature of Cortex XDR by Palo Alto Networks is the low consumption of system resources. The solution uses a lot of AI and machine learning."

"Cortex XDR's most valuable feature is its intelligence-based dashboards."

"Stability is a primary factor, and then there's the ease of distribution and policy management; Cortex XDR by Palo Alto Networks is very easy to work with, and we're quite happy with them."

"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."

"The ability to kind of stitch everything together and see the actual complete picture is very useful. I guess you'd call it a playbook. Some people call it the forensics analysis of what was happening on particular endpoints when they detected some malicious behavior, and what transpired before that to cause that. It is also very user friendly. The way they have done everything and integrated all the solutions that they've purchased over the years to make it a very seamless, effective product is very good. One thing about Palo Alto is that they take the products or services that they purchase and make them seamless for the end user as compared to some companies that purchase other companies and then just kind of have their products off to the side or keep different interfaces. Palo Alto doesn't do that."

More Cortex XDR by Palo Alto Networks pros

"The product has valuable features for cloud IoT device enhancement, intelligent threat detection, etc."

"The threat intelligence is excellent."

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

"Microsoft Defender XDR has significantly improved our operational security."

"The ability to hunt that IM data set or the identity data set at the same time is valuable. As incident response professionals, we are very used to EDRs and having device process registry telemetry, but a lot of times, we do not have that identity data right there with us, so we have to go search for it in some other silo. Being able to cross-correlate via both datasets at the same time is something that we can only do in Def"

"Microsoft 365 Defender is simple to upgrade."

"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."

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

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

Cons

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

"The downsides of Cortex XDR by Palo Alto Networks are that in many incidents, when I enter the causality chain, there are numerous logs."

"I would like to see them include NDR (Network Detection Response). Then it would work well with SIEM Response."

"It would be better if they could educate the customers more. Some sort of seminars and roadshows will help educate the customers and show what the product can do. The price could be better. It would also help if they had a team for deployment and support."

"Data privacy is a matter of concern. You have to be careful with data privacy, it can be sensitive and Cortex can have most of your access."

"The solution should force customers to integrate with network traffic to see the full benefits of XDR."

"It's more focused on network communication. If a customer wants to increase the level of protection and start working with documents, it's impossible to integrate these features into the system. It's more of a communication-oriented system than a content security-oriented system."

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

More Cortex XDR by Palo Alto Networks cons

"The product is more expensive than other vendors in terms of features."

"The cost can be high if you want to build custom license packages. Another area for improvement is the policies. In Azure, we need to implement policies in JSON format, but in 365 Defender 365, it would be helpful to use a different format so we can customize the platform."

"Microsoft could improve on threat hunting and build more on threat detection and handling. The cybersecurity and cloud security posture features are a bit lesser than standard security products."

"For Microsoft Defender XDR, there is currently no ability to reset passwords for on-premises accounts, which is a key challenge."

"The solution could enhance the threat Intelligence feature by making it more relevant to specific industries. Much of the threat intelligence information isn't directly applicable to our environment. It would be beneficial if the threat intelligence were tailored to the industry, such as healthcare or fintech, where the solution is being used."

"There should be better information for experts on features in the solution. What I see when reading about features in Microsoft 365 Defender is that it is always general information. If Microsoft could go deeper into details for the experts about how to use the tools, usage of it would be more familiar and it would be easier to use."

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

"The onboarding and offboarding need improvement. I work with other vendors as well, and they have an option to add a device or remove a device from the portal, whereas with Microsoft 365 Defender, we need to do that manually. However, once you do that, everything can be controlled through the portal, but getting the device onboarded and offboarded is currently manual. If we have an option to simply remove a device from the portal or get a device added from the portal, it would be more convenient. The rest of the features are similar. This is the only area where I found it different from others. I would also like to be able to simply filter with a few of the queries that are already there."

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

Pricing and Cost Advice

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

"Traps pays for itself within the first 16 months of a three-year subscription. This is attributed to OPEX savings, as security teams spent less time trying to identify and isolate malware for analysis as a result of a reduction in malware incidents, false positives, and breach avoidance."

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

"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."

"I don't recall what the cost was, but it wasn't really that expensive."

"It's about $55 per license on a yearly basis."

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

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

More Cortex XDR by Palo Alto Networks pricing and cost advice

"The product is more expensive than other vendors in terms of features."

"The pricing of Microsoft 365 Defender is definitely on the costly side, but with the features and services that Microsoft provides, such as the seamless integration of all the Defender tools, while the price is on the higher side, there is no alternative."

"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 plan 1 is tenant-wise, and Defender plan 2 is per-user, which makes it more expensive. To have certain features, you would need to purchase the E5 license. For all of the capabilities that the tool provides, the price, though it can be high, is fair."

"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."

"Microsoft Defender XDR is included in our license."

"They have moved from a licensing model to pay-per-use... The question is: What happens if, for any reason, there's not enough budget to accept this model? That could be a great problem."

"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."

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