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.

Advanced AI-driven monitoring has strengthened investigations and now prioritizes critical threats

I would not say there is anything that could be better in SentinelOne Singularity AI SIEM; I think we have seen something unique in the product. This product has the potential to add more SOC functionality on top of its SIEM, which can automate a few more things because I have the information there. I need to do what I would call security agents or agentic AI to be built on top; it can take care of a lot more analysis and actions. Maybe licensing cost can also be looked at and reduced. We are still to see the automated feature work a little bit more; we are not really using it to the full extent.

Quotes from Members

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

Pros

"The solution allows control over the user and his machine through Cortex XDR security policies."

"The stability of the solution is very good, we have about 100 users on it right now, and we use it twice a week."

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

"Previously, we had to install endpoint protection per machine and then scan and update, but Cortex XDR basically does that centrally and predictably, so we have more time to do day-to-day work rather than spend time chasing those endpoints."

"The most valuable aspect of Cortex XDR by Palo Alto Networks for me is its integration with AI detection, where we get to know the behavioral detection based on users, traffic patterns, and different services that we consume."

"The stability is pretty good except for one or two cases, and based on the performance, it's been okay with pretty high performance, no bugs or glitches, and it doesn't crash or freeze."

"My advice for anybody who is considering Cortex XDR is that it is a complete solution, and has very good features."

"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."

More Cortex XDR by Palo Alto Networks pros

"Advanced hunting is good. I like that. We can drill down to lots of details."

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

"I like that it's fully integrated with Windows, Microsoft 365 Exchange Online, and Outlook. It is better than other antivirus solutions because it's fully integrated with all Microsoft products. It's easy to integrate them and onboard all Windows devices from SCCM."

"The most valuable feature is the DLP because that's where we can have an added data protection layer and extend it not just to emails but to the documents that users are working on. We can make sure that sensitive data is tagged and flagged if unauthorized parties are using it."

"Within advanced threat hunting, the tables that have already been defined by Microsoft are helpful. In the advanced threat hunting tab, there were different tables, and one of the tables was related to device info, device alert, and device events. That was very helpful. Another feature that I liked but didn't have access to was deep analysis."

"Defender XDR has a feature called the timeline that lets you track all activities. It helps a lot with investigations."

"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."

"Microsoft 365 Defender is simple to upgrade."

More Microsoft Defender XDR pros

"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."

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

"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."

"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."

Cons

"The tool needs to be improved in terms of integration and interface."

"The configuration could be simplified. I would like to see better protection, specifically to protect email applications."

"A better pricing plan would make this product more competitive."

"I have seen lagging with Cortex XDR by Palo Alto Networks. There was one time when we faced a threat actor trying to gain access to our system. When our team utilized the tool, we were all on the same dashboard and we faced a lag issue at that time of around five minutes, which was quite significant."

"I would like to see them include NDR (Network Detection Response)."

"Cortex XDR by Palo Alto Networks could improve by adding a sandbox feature to better compete with their competitors which have it."

"It is not a suitable solution if you are looking for a single product with multiple features such as DLP, encryption, rollback, etc."

"They have the worst support, as a company, that I have ever worked with, as they are difficult to get a hold of and keep on the phone. They don't know what they are talking about when you get them on the phone. They don't like to respond to messages when you send them to them. They like to "research problems" for weeks on end, then pass you off to somebody else."

More Cortex XDR by Palo Alto Networks cons

"The price could be better. It'll also help if they can continuously update and upgrade the solution."

"The user interface of Microsoft 365 Defender could improve. They could make it simpler."

"The web filtering solution needs to be improved because currently, it is very simple."

"The initial time spent setting up and configuring Defender XDR is a bit longer than the other solutions. If everything were on one portal, the platforms for managing policies or alerts would be simpler. We must automate and manage policies on Intune rather than the same portal."

"Automated playbooks and automated dashboards would be preferable to the way the data is currently being presented."

"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."

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

"The dashboard should be easier to use. There is also improvement needed in the reporting when it comes to exporting or scheduling reports."

More Microsoft Defender XDR cons

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

"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."

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

Pricing and Cost Advice

"I don't like that they have different types of licenses."

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

"The tool's price is moderate."

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

"Cortex XDR's pricing is ok."

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

"Cortex XDR’s pricing is very reasonable."

"I am using the Community edition."

More Cortex XDR by Palo Alto Networks pricing and cost advice

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

"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."

"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."

"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."

"While the standalone price of Defender XDR might seem high, its value becomes clear when considering the ease of implementation and smooth integration with our existing Microsoft infrastructure, especially when bundled with other Microsoft products."

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

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

"The solutions price is fair for what they offer."
