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.

Brand threats have been monitored proactively and intelligence now drives daily security decisions
I am an end user of Mandiant Advantage. Mandiant Advantage's intelligence is good, and their service is good, but the price they charge is just too high. It's not that they're not supplying what they're selling; it's simply that the price is high, and putting a tag on that cost is somewhat problematic. I would rate Mandiant Advantage an 8 out of 10. I do not consider Mandiant Advantage an affordable solution at all. The prices are very high and very expensive. The price of Mandiant Advantage is not justified. It's really expensive, and it's so expensive that I'm not sure I will continue next year with their service.

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.

Quotes from Members

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

Pros

"The dashboard is customizable."
"From a single pane of glass, you can easily manage all of your endpoints."
"One thing that I like about Cortex XDR by Palo Alto Networks, it is detecting all the suspicious or malicious binaries, and it has integration with Palo Alto Firewall."
"Traps has drastically reduced our endpoint attack surface via advanced detection capabilities, sandboxing of never before seen programs, and by drastically limiting where executables can launch in the first place."
"We can visualize and control the activities in the environment from anywhere."
"Once you become familiar with it, Cortex XDR by Palo Alto Networks is a more powerful tool and I would say that I prefer it over MDE because it is a stronger tool for me."
"The user interface of the solution is sophisticated and straightforward."
"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 feature I have found most valuable is directory monitoring. We experienced an instance of threat actors trying to ensure a complex and massive attack against our customer's infrastructure on the forum. That is, they were animating people on a formum. The solution alerted us to this two days ahead of the attack, which gave us plenty of time to prepare for it."
"The live IOC feed identifies the type, technique, and tactics used."
"Mandiant Advantage is excellent at providing the full context and all the information, where the information was found, and the full data, including the raw data that was uploaded onto the Internet."
"I have never faced stability issues."
"The advantage of the solution is being able to go look up threat actors and get a lot of detailed information about different attacks and different tactics and general information about threats."
"Mandiant Advantage has helped me enhance operational efficiency overall because it enriched our SIEM, which is Splunk, and the YARA rules I wrote within the platform help me understand better what my threat landscape is."
"It is so valuable to have someone performing these functions outside of our business hours when we don't have staff in the building. We've seen a lot of solid metrics on the amount of malware that it's detecting and resolving. We're pleased with it so far."
"The scalability of Mandiant Advantage deserves a ten out of ten."
"The common and advanced security policies for threat hunting and blocking attacks are valuable."
"It has been great for us. Previously, we didn't have a solution to protect us, especially from malware, whereas now, we are getting protection up front, especially from the malware attacks coming through emails or endpoints."
"Many people don't realize that Microsoft Azure, Exchange Online, and the security and compliance portal all sync together. For instance, within the Azure portal you can set security restrictions and policies to help secure your tenants... The good part of it is that these products have already been integrated. When you sign on as an admin you have global admin rights and that gives you access to all these features."
"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."
"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."
"Microsoft 365 Defender is a good solution and easy to use."
"In Microsoft 365 vendor products, monitoring and connectivity across all Microsoft and third-party connectors enable viewing of all activity within those environments."
"It reduces the risk of users accidentally clicking on phishing emails."
 

Cons

"It would be good if they could make an exception for applications. Sometimes, it can be a bit of a challenge to make exceptions for certain applications that have been used as rogue."
"Technology evolves every day, so it would be nice if it gets more secure. It can also have more integration with other platforms."
"It'll help if customization was easier."
"Cortex XDR could be improved with more GUI features."
"The solution needs better reports. I think they should let the customer go in and customize the reports."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"The solution could improve by providing better integration with their own products and others."
"Cortex does not offer an on-premises solution. However, some customers would prefer not to be on the cloud. It would be ideal if it could offer something on-prem as well."
"I think that the data query that is used for data cloud language should be improved. It's really hard to query actual data from the platform."
"Mandiant Advantage's platform itself is not good yet. They have many bugs because they changed the platform, so from time to time it's simply not working at all."
"Collaboration of data in my view becomes a bit clogged, requiring effort to understand visually."
"They could have better support. Now that they've merged, they are moving towards a portal system, which isn't very helpful."
"Sometimes Mandiant Advantage becomes noisy when dealing with widely recognized companies due to false positives."
"I have already given them feedback that their UI needs improvement since sometimes there is a lag. The side-by-side depiction of request response and action clogs the screen."
"Sometimes Mandiant Advantage becomes noisy when dealing with widely recognized companies due to false positives."
"Mandiant's on-prem client is too processor-intensive, so it's putting a strain on the local device's CPU. When a scan is running on the device, the other processing tasks slow to a crawl. We're still trying to figure out the correct settings for the client."
"I would like more of the features in Defender for 365 to be included in the smaller licenses. Even if I buy a small license and don't need everything, security shouldn't be a question. Security is one of the main aspects of all projects from our side, so it would be nice to have more features in the smaller licenses."
"Stability could be improved by avoiding frequent changes to the interface."
"The user interface of Microsoft 365 Defender could improve. They could make it simpler."
"Their response time is okay, it works fine, but the time it takes to resolve escalated cases needs improvement."
"The licensing is a nightmare and has room for improvement."
"I personally have not seen much evidence of how Defender can enhance the story of zero trust for enterprises."
"It would be helpful if the solution could scan faster when it comes to scanning attachments to emails."
"Troubleshooting in Microsoft 365 Defender can be inefficient."
 

Pricing and Cost Advice

"Our customers have expressed that the price is high."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"It's the most expensive solution, but features-wise, it's quite strong. It's very good for protection, so the results are very good in the case of protection. I would rate it a two out of ten in terms of pricing."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"I don't have any issues with the pricing. We are satisfied with the price."
"We pay about $50,000 USD per year for a bundle that includes Cortex XDR."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"The price of the solution is high for the license and in general."
Information not available
"Microsoft Defender XDR is priced high."
"The bundling of software makes it easier to manage our setup, but Microsoft purposefully obfuscates this through marketing ploys to hide costs."
"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."
"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."
"There are no issues with pricing, but sometimes, the clarity in licensing is a concern."
"Microsoft is not competitive with the pricing of the solution. The competitors are able to offer lower discounts. The price of the solution is higher."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"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."
