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.

Centralized policies have improved remote endpoint control and have simplified data visibility
The integration is not simple and easy. It requires experienced users or people who have done the implementation. When certain policies are applied, they do not immediately push the policies. For example, we manage endpoint device USB access. We set a policy to block it, but it does not come into effect immediately. Sometimes it takes three or four days for it to reflect. That is a pain point. I have raised this issue with support as well, but they said that I need to limit the number of devices in the policy. In terms of application deployment, for us, it was seamless.

Quotes from Members

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

Pros

"Palo Alto Networks Traps improves our security posture and lowers risk by providing next-gen methods to combat against modern threats on all the major platforms."
"I generally believe that Cortex XDR by Palo Alto Networks is probably the best in the market right now."
"Cortex XDR is stable, offering high quality and reliable performance."
"Palo Alto is the best security solution in the market."
"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"Cortex XDR is a simple platform that's easy for administrators and users. You have a lot of flexibility to change or customize the features."
"Traps pays for itself within the first 16 months of a three-year subscription."
"The solution's most valuable feature is the user interface."
"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."
"Its most significant advantage lies in its affordability."
"I have found the ability to delete unwanted threats beneficial."
"It's a very scalable tool that can be used in a very small environment or in a very large environment. Everything can be managed from a simple dashboard and can be scaled up or down depending on the customer's environment."
"Vulnerability assessment and just-in-time access are some valuable features of Defender for server plans."
"Overall, the comprehensiveness of the threat protection is at 95 percent."
"From an attack chain perspective, Defender XDR handles phishing and spam emails easily, while Defender for Endpoint manages endpoints effectively. We've drastically improved our user experience."
"The proactive remediation aspects and the surfacing of suspicious activity for investigation and escalation are the key aspects we appreciate most."
"For inventory purposes, it's from one of the best things on the scene, as you can get live inventory."
"Tanium has made the process of detecting threats more proactive with its detection, so the process is easier and more efficient."
"Tanium’s best features include support for any Windows, Linux, or Mac endpoint, regardless of where it is, and the ability to do IT operations and security operations."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"Tanium is stable and it is also lightweight."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"Threat hunting is a very good feature on Tanium. We have just started using it and have not used it extensively."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
 

Cons

"The solution eats memory of the computer, unlike anything I've ever seen."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"Cortex XDR could be improved with more GUI features."
"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"We would also like to have advanced tech protection and email scanning."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"The product's pricing could be better."
"While the XDR platform offers valuable functionalities, it falls short of other solutions in its ability to deliver a cohesive identity experience."
"Improving scalability, especially for very large tenants, could be beneficial for Microsoft Defender XDR."
"The solution can improve the rules and privileges it offers."
"Microsoft 365 Defender does not have a unique package with emerging endpoint security technologies, such as EDR and XDR."
"Microsoft could improve on threat hunting and build more on threat detection and handling."
"The price could be better. It'll also help if they can continuously update and upgrade the solution. Every day there's a new virus uploaded into the network, and we have to keep updating it to identify all these things."
"I personally have not seen much evidence of how Defender can enhance the story of zero trust for enterprises."
"The logs could be better."
"The solution can give a lot of false positives."
"The most painful thing is the interface. It's a bit unclear sometimes."
"Most of the time, agent-relative issues have to be more equipped with self-healing features."
"The problem or challenge is a pre-sales and go-to strategy for the SMB market delivered through a channel or model. It's very convoluted and vague, which leads to some confusion about the various types of modules, and the device-to-seat cost is extremely difficult to calculate."
"The solution lacks mobility."
"The solution needs to improve the reporting and tracking capabilities."
"The performance could improve in future releases. We have had performance issues in specialized web environments, but overall I think the problems are less than 2% of the computer systems being used."
"There are some bugs in the product. The tool needs to improve in the area of reporting."
 

Pricing and Cost Advice

"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"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."
"The solution is expensive. It's pricing is on a yearly-basis."
"I am using the Community edition."
"It is "expensive" and flexible."
"I don't like that they have different types of licenses."
"It has reasonable pricing for the use cases it provides to the company."
"Compared to CrowdStrike, Cortex XDR is an expensive solution."
"All I can say again is the E5 gives you all the capabilities that it offers. It also gives Office 365 and one terabyte of storage. All in all, the E5 license model makes sense. There are some people who say it's quite costly, but rather than paying different vendors, it makes sense to go all in with Microsoft if you've got that licensing. From that perspective, it's cost-effective, but I can't comment much on that."
"The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"I believe the pricing is fair and acceptable. I consider it to be reasonable and satisfactory."
"The license cost for a year is approximately forty-four thousand, and this annual saving is a significant factor in our decision to switch."
"Purchasing Microsoft Defender XDR as part of a Microsoft 365 bundle can be cost-effective, but acquiring it as a standalone product may be more expensive."
"Microsoft Defender XDR is already included in our Office 365 licensing. It is better because we're saving money by using it."
"Microsoft purposely makes its license combinations complex and includes combinations like Microsoft 365 E3 and Microsoft 365 E5, Office 365 E3, Office 365 E5, and Office 365 E1, so you get confused. Microsoft tries to sell you a bundle of a lot of things together."
"It's an expensive solution. It would be nice if the cost were lower."
"The solution offers value for money."
"It is higher than some competitors in the market."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"The solution is expensive but it's a good investment."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"There is an annual license required to use this solution."
