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.

Automatically isolates threats and integrates with logging to reduce response time
Overall, I would evaluate the Microsoft support level that I receive at probably about a seven, but that depends on the day. It has been spotty. We have had issues where the urgency level of the Microsoft support is not as high as ours, especially during a data breach or potential data breach situation. We have had issues with some of the offshore support being lackluster. One specific thing that comes to mind is we were on a support call with our CISO on the call, and the Microsoft agent, who did not actually work for Microsoft, is one of the vendors that Microsoft uses for support, said, "Just to set expectations, my lunch break is in an hour and I am going to go away then." For us, it was already ten o'clock at night and we had been working on this for a couple of hours, trying to get a security engineer on with us. For him to tell us that he was going to go away and have lunch, it was, "Okay, but go find somebody else if you need to." It was just the lackluster approach, and it seemed like he did not really care. We seem to get a lot of this when we get non-Microsoft support. I can identify areas for improvement with Microsoft Defender for Endpoint, as it is kind of a convoluted mess to try to take care of false positives. Especially when they have been identified as false positives but they keep going off over and over again. It is great for my pocketbook because it generates a lot of on-call action, but I would really prefer more sleep at two o'clock in the morning than dealing with false positives. I would say that the unified portal for managing Microsoft Defender for Endpoint is suitable for both teams as they are all in there. It would be great if they would stop moving things around and renaming things, which makes sense. The new XDR portal is pretty nice. Being able to have it central again inside of the regular Security Center without having to open up two windows is helpful. Overall, I think it is pretty good. There is always going to be something that could be improved, such as alerting and the ability to modify alerts would be a little bit helpful to have. Being able to add more data into the alerts and turn off alerts that are not as useful would be beneficial. It is hard to say what the quantitative impact the security exposure management feature has had on our company's security, because a lot of it is kind of subjective. I think we are sitting at around a fifty percent score still, and a lot of it is just kind of unusual circumstances that we cannot really implement without breaking the organization.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"The initial setup is pretty easy."
"The solution doesn't need a high level of technical training."
"Cortex XDR can integrate the firewalls and determine the tendencies of the attacks. It's a new generation antivirus, with protection endpoints and detection response. It is very easy to use and everybody can operate the solution."
"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."
"It is easy to use."
"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."
"The solution allows control over the user and his machine through Cortex XDR security policies."
"The solution helps find bugs, and it is safe to use to prevent attacks by hackers."
"I find the entire Microsoft Defender for Endpoint valuable because it finds not just definition-based threats but also behaviors."
"Auto-remediation: When the product sees malware, it resolves the issue immediately. This protects the machine."
"The visibility into threats that the solution provides is pretty awesome... This is something that makes me think, "Wow, okay. If I had my own organization, I would probably get this too." It stops the threat before an employee gets phished or something gets downloaded to their computer."
"We are able to productively integrate with existing on-prem, hybrid, or cloud applications."
"Microsoft Defender has helped me reduce mean time to remediation."
"It's great for investigating what's happening on a machine. They show a whole bunch of machine timeline events that are related to a security incident. They have quite good details on the things related to threat and vulnerability management, such as any weakness that has been disclosed publicly, assets that are exposed, and if there is an exploit active in the wild for that vulnerability. It can provide you with all such information, which is cool."
"The attack surface reduction rules are the most valuable. We're able to have unattended remediation actions when the solution works side by side with a local antivirus like Microsoft Defender or Kaspersky. The attack surface reduction rules help us to proactively block and stop threats."
"It captures data through machine learning, which is built-in on the back-end. It also provides built-in analytics and a threat intelligence feature. It is a one-stop solution that doesn't require an antivirus because it comes prebuilt into Windows 10."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"For Cortex XDR by Palo Alto Networks, if I had to point out improvements, I would say the UI is still somewhat difficult for beginners."
"I would like to see them include NDR (Network Detection Response)."
"The setup is quite easy. We had appropriate support from the manager. One thing that was missing was the integration part."
"Limited remote connection."
"It automatically detects security issues. It should be able to protect our network devices while operating autonomously."
"Cortex XDR should have a lightweight agent, and the agent size should not be heavy."
"Cortex XDR by Palo Alto Networks could improve by offering remote management. It would be useful to look at the client's issue to fix it."
"If you compare it to SentinelOne, which has more functionalities and detection capabilities on an open platform, the pricing on SentinelOne is far more reasonable and cheaper than Cortex XDR by Palo Alto Networks."
"The interface isn't necessarily intuitive to a nontechnical person. You can get stuck in the little endpoint security portal. Sometimes, if you uninstall a competitive product, the end user doesn't always know if it's running or if they're protected even though it's silently running. There could be a notification, widget, or something that's resident on the screen for at least a bit, especially if you're doing remote support. You want to talk them through it, but sometimes, we're not allowed to look at the PCs we support."
"There's a lot of manual effort involved to configure what we need."
"For us, Microsoft Defender for Endpoint can be improved by providing better visibility into our developers' environments, especially as we try to integrate a lot of the AI coding environments, such as Windows Services for Linux v2."
"Windows Firewall is integrated with Windows Defender. Over the last few days, I have had a problem with defining a wildcard on Windows Firewall. For example, I wanted to pull out the connection of my program and install a software package with a lot of executable files. I wanted to prevent it from accessing the internet. I could not select executables by using a wildcard. I had to select a single executable with its full name."
"On the Mac OS platform, there is no parity between Windows and Mac OS. The solution is very feature-rich and very well-integrated into Windows, and I guess baked into Windows 10 and Windows 11. Whereas, on the Mac OS platform, there is still some work there to give it a more feature-reach platform."
"The scanning is slow when it is working with incoming emails."
"If they integrate with the EDR then it will benefit this solution."
"Its price could be better."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"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."
"The pricing is a little high. It is per user per year."
"It is "expensive" and flexible."
"I don't recall what the cost was, but it wasn't really that expensive."
"Cortex XDR’s pricing is very reasonable."
"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."
"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
"Microsoft Defender for Endpoint can be costly as a standalone solution."
"I got it with the Microsoft Windows license."
"There is no licensing fee."
"The nice thing about Defender and Sentinel is that the cost is based on the data logs that you ingest from the Defender endpoints and data connectors. I don't have to buy a 25- or 50- or 1,000-user or enterprise license. I can buy one license at a time."
"I do not have to purchase antivirus solutions anymore because Microsoft Defender for Endpoint is integrated into Windows and comes free."
"When compared with other vendors, the pricing is very high."
"It's all pretty easy. For some clients, it's an easier sell because it's just an add-on to their existing Microsoft licensing and Office 365 licensing."
"It's included with the Windows Operating System, I don't pay for any licensing fees."
"It’s a single license platform."
