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.

AI-driven monitoring has improved real-time threat detection but still needs better automation

I could see some workflows, but I am unable to do automated workflows. For example, some repetitive jobs or repetitive tasks I am doing, but I am trying to have less manual intervention on the front. I am raising some issues that should be resolvable. The SentinelOne team has told me that this can be resolved within a couple of months, but they are saying that it is in future for enhancement and it may take some time. So far, the numbers are great. Regarding disadvantages or areas for improvement, I could say that 35 percent of my manual effort can be detected since I implemented it very recently. I could be able to say my current data talks about only 35 percent, and it may improve further, as I am expecting. But I can only comment based on my alerts and events. The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things. This will take some more time, probably another month. Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well.

Quotes from Members

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

Pros

"It collects and caches and the knowledge of machine learning from different customers to take to the cloud, it makes it better to use for everybody, it allows for quick learning and updates and can, therefore, offer zero-day malware security, and this sharing of metadata helps make the solution very safe."

"We have found in our test Cortex XDR by Palo Alto Networks to be a very good tool."

"The most valuable feature is that you can select remote access of any machine for sandboxing."

"The solution's most valuable feature is its ability to rapidly detect certain hardware files."

"The solution helps find bugs, and it is safe to use to prevent attacks by hackers."

"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."

"My advice for others looking into using Cortex is that it is very easy to use and very useful for the customer environment, whether it's a public or private one."

"We use Cortex XDR by Palo Alto Networks for its ability to detect based on behavior rather than simple virus scan to prevent malicious activities."

More Cortex XDR by Palo Alto Networks pros

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

"What I like most about the product is its all-in-one solution. With Microsoft Defender XDR, we get coverage for various aspects like endpoint security, cloud security, and image-related cases, all within a single platform. This eliminates the need for multiple products or technical controls to address incidents. The main benefit became evident immediately after deployment, especially in its ability to analyze files and phishing emails quickly. By submitting suspicious files or emails, we receive quick results on whether they are legitimate, suspicious, or malicious, saving time."

"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."

"Microsoft Defender XDR's capability to automatically disrupt advanced cyber attacks is very effective."

"We are able to consolidate licences and make use of many Microsoft products using this solution. If we have any Microsoft customers, we encourage them to use this solution for enterprise defence."

"The most valuable feature is the network security."

"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."

"What I found most valuable in Microsoft 365 Defender is that it's able to scan emails and protect users from dangerous links or attachments."

More Microsoft Defender XDR pros

"When they face attacks such as ransomware and are dissatisfied with their existing solutions, they switch to SentinelOne Singularity AI SIEM, which is quite good in detecting unknown threats, cleaning the system, and handling ransomware."

"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."

"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."

"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."

"SentinelOne Singularity AI SIEM's AI-powered analytics does affect our SOC's ability to reduce false positives; that is one of the biggest advantages because the manpower that I have is limited."

Cons

"We would also like to have advanced tech protection and email scanning."

"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."

"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."

"It would be good to have a better way to search for a file within the UI."

"There's room for improvement with Mac device installations, which can be challenging."

"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."

"One thing that was missing was the integration part. Currently, they don't have out-of-box integration with IBM QRadar, or if they have the integration, the integration doesn't work well."

"Managing the product should be easier."

More Cortex XDR by Palo Alto Networks cons

"365 Defender has multiple subsets, including Defender for Cloud Apps. When integrating Defender for Cloud Apps with apps on third-party cloud platforms like AWS or GCP, there are limitations on our ability to control user activities. If Microsoft added more control over third-party products, that would be a game-changer and help us quite a lot."

"Advanced attacks could use an improvement."

"Since all of our databases are updated and located in the cloud, I would like additional support for this."

"The solution could improve by having better machine learning and AI. Additionally, the interface, documentation, and integration could be better."

"It would be beneficial to reduce the number of clicks required to navigate between blades, as the current navigation and breadcrumb system can be a bit confusing. Some inconsistencies exist between blades, which could be improved for a more seamless user and UI experience."

"The support from Microsoft could improve. There are times I have to wait for a response from a qualified specialist."

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

More Microsoft Defender XDR cons

"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."

"It is quite good, but the only downside is that it is costly."

"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."

"At the moment, I feel the pricing is a little bit on the higher side, but the tool is positioned in a place where risk is very high, and we do not want to take chances, so we are prepared to pay the premium."

"In AI SIEM, the areas that have room for improvement are the parsers for third-party integrated data or for third-party data sources that are not native integrations, which could be made a bit easier."

Pricing and Cost Advice

"The solution has one subscription for endpoint protection and one subscription for detection and response. The two licenses combined give you the BRO version."

"Cortex XDR's pricing is ok."

"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."

"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."

"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."

"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."

"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."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"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."

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

"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."

"Microsoft 365 Defender offers competitive pricing."

"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."

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

"I would like to have more security features in the lower licenses because not every customer is able to buy E5 licenses. The bundling isn't always easy for our customers to understand. Compared to other tools, it's a good price."

"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."
