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.

A scalable and stable solution with straightforward deployment
We can generate maps from the environment. For example, suppose there is a virus that has a zero-day attack and is publicly unknown. We can block that and keep it away from the network so it is not further replicated. It also has custom white and black lists. We can add a good reputation on both lists and use the sonar technology for Symantec and the online network for advanced reports.

Quotes from Members

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

Pros

"I can highlight that we have not faced any security incidents with Cortex XDR by Palo Alto Networks, and even though our environment is quite dynamic, we have not faced any security incident with Cortex XDR by Palo Alto Networks until now."
"We can visualize and control the activities in the environment from anywhere."
"Palo Alto is the best security solution in the market."
"Cortex XDR alerts us on the dashboard when there's a threat, which allows us to restrict that user and helps secure our infrastructure."
"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."
"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."
"The solution allows us to make investigations. Other XDR solutions also provide similar capabilities but for investigation, Cortex XDR is better."
"WildFire AI is the best option for this product."
"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 Sentinel enables you to ingest data from your entire ecosystem, investigate threats, and respond from one place, which has reduced our time to detection and time to response by about 20 percent."
"The advantage of Microsoft Defender XDR has over other XDRs in the market is that it's easy to use. You can quickly differentiate between alerts, incidents, devices, software, etc. It's easier to investigate an incident, and you have so many options. You can automate investigations and use playbooks. There's also the live response session, which is something you can't find in any other XDR."
"Microsoft XDR's system of analysis and investigation is super convenient for our customers. It integrates with other Microsoft solutions like Defender for 365 to protect email traffic from malicious external web links and phishing."
"Microsoft 365 Defender is a stable solution."
"Its most significant advantage lies in its affordability."
"The most valuable feature of all is the full integration with the rest of the software in the operating system and Office 365, as well as Microsoft SCCM. It is quite easy for us to work with the whole instance of Microsoft products. This integration improves the benefits of the whole suite of products."
"The feature I like the most in Microsoft Defender XDR is XDR because it has taken us a while, but we are a global company with people in a few countries, and now we can have centralized alerts that we send out to Teams messages and clean up infected computers or help people in a very short amount of time."
"You can advise the solution and protect your environment."
"We can block a virus that has a zero-day attack and is publicly unknown and keep it away from the network so it is not further replicated."
 

Cons

"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."
"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."
"A better pricing plan would make this product more competitive."
"The solution should force customers to integrate with network traffic to see the full benefits of XDR."
"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."
"The only issues that we have are, one the cost, two the dashboard is not very intuitive, even though you can drill down within the dashboard, we usually have to gather information from other sources to determine locations and if its a false positive."
"Being able to filter the events to see those that are related to the actual alert would save time spent by the engineer."
"It is not easy to sell Cortex XDR, not because it isn't a good tool. Its marketing needs to be improved."
"Microsoft support is not very good. You get stuck in low-level support for way longer than you should, instead of them escalating the issue up the chain."
"Every now and then, Microsoft Defender XDR seems to go through and aggregates almost a week's worth of incidents and wraps them up, indicating a huge problem."
"From an integration standpoint, it is always improving overall. With Security Copilot coming out, as partners, we are waiting for the GDAP support so that we can actually see Security Copilot on behalf of customers if they subscribe to it."
"For some scenarios, it provides good visibility into threats, and for some scenarios, it doesn't. For example, sometimes the URLs within the emails have destinations, and you do get a screenshot and all further details, but it's not always the case. It would be good if they did a better job of enabling that for all the emails that they identified as malicious. When you get an email threat, you can go into the email and see more details, but the URL destination feature doesn't always show you a screenshot of the URL in that email. It also doesn't always give you the characteristics relating to that URL. It would be quite good if the information is complete where it says that we identified this URL, and this is what it looks like. There should be some threat intel about it. It should give you more details."
"Microsoft Defender XDR could be improved with a lower price."
"Sometimes, configurations take much longer than expected."
"At times, there may be delays in the execution of certain actions and their effects."
"Microsoft frequently changes the names of its products, sometimes even renaming entire portals or features."
"The solution should have better reporting."
 

Pricing and Cost Advice

"It has a yearly renewal."
"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 like that they have different types of licenses."
"In terms of the cost Cortex XDR by Palo Alto Networks is very expensive because we are a Mexican company and when you translate dollars to pesos the cost is very high. The solution is very expensive for Mexican companies. I understand that they have international prices, but I do not think it offsets the price enough for many companies in countries, such as Mexico. The amount it is reduced is not a massive percentage."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"The price is on the higher side, but it's okay."
"Cortex XDR's pricing is ok."
"Its pricing is kind of in line with its competitors and everybody else out there."
"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."
"The solution is too expensive."
"Microsoft Defender XDR is included in our license."
"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."
"It is fairly priced because we get complete integrated services with the E5 license."
"The price of the solution is high compared to others and we have lost some customers because of it."
"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."
"On average, we pay around 55 euros per user for the services and features we receive."
