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.

I also like the ability to remotely manage update packages on your systems, and the fact that there is an open source version
Setting OpenEDR was challenging at first, but I got it done by following their documentation and online videos. You need to install the client and configure it to work with their online open platform. Next, you have to configure it on the device if it's a phone. You input a cloud link to the EDR, so you can monitor it from the cloud. There isn't any maintenance aside from updating the client. It's mostly on the cloud.

Quotes from Members

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

Pros

"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."
"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"Monitoring is most valuable."
"Palo Alto is constantly adding new features."
"It can automatically correlate events and logs, which is very helpful for an IT administrator. It can correlate different kinds of malware activities over a network, agent, or host system. You do not need to do it manually. It is a good feature. It is also a user-friendly solution. We have deployed it on the cloud because our space does not provide any flexibility for on-premises deployment, but Palo Alto has added some flexibility to install it on-premises. It must be like the same Cortex XDR agent for all the VPN services, web filtering services, and everything else."
"Cortex XDR by Palo Alto Networks has helped lighten the load of our security analysts because it was the major tool that we were using and the one we utilized most."
"Cortex XDR lets us manage several clients from the same console, and its endpoint defense is more advanced than traditional antivirus."
"The most valuable features are incident creation, policy-based protection, IP whitelisting, and device encryption. These are beneficial for endpoint and server security."
"It reduces the risk of users accidentally clicking on phishing emails."
"The integration with other Microsoft solutions is the most valuable feature."
"The product is very easy to use."
"The EDR and the way it automatically responds to ransomware and other attacks are valuable features."
"The ability to hunt that IM data set or the identity data set at the same time is valuable. As incident response professionals, we are very used to EDRs and having device process registry telemetry, but a lot of times, we do not have that identity data right there with us, so we have to go search for it in some other silo. Being able to cross-correlate via both datasets at the same time is something that we can only do in Def"
"In Microsoft 365 vendor products, monitoring and connectivity across all Microsoft and third-party connectors enable viewing of all activity within those environments."
"The incident threat response and its ability to facilitate effective remediation against threats are the standout features."
"The integration between all the Defender products is the most valuable feature."
"Comodo includes a firewall and antivirus in one solution. I also like the ability to remotely manage update packages on your systems. Comodo can even find a lost device and secure it remotely."
 

Cons

"The solution can never really be an on-premises solution based simply on the way it is set up. It needs metadata to run and improve. Having an on-premises solution would cut it off from making improvements."
"There is a severe gap in functionality between Windows, Linux, and Mac versions. For example all folder restriction settings are Windows only. Traps 5.0+ does not have SAML / LDAP integration."
"It takes time to scan the servers and devices."
"We have found that there are times Cortex XDR by Palo Alto Networks does not detect some of the viruses, we have to use another protection solution called Kaspersky."
"It is an enterprise-level solution. Its price could be less expensive."
"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 setup is quite easy. We had appropriate support from the manager. One thing that was missing was the integration part."
"It tends to do 99.9% of things. The only thing I'd like is single sign-on authentication into their cloud platform so that my users can be properly authenticated against it."
"Microsoft tends to provide too many features, which makes the solution prone to bugs."
"The documentation on their website is somewhat outdated and doesn't show properly. I wanted to try a query in Microsoft Defender 365. When I opened the related documentation from the security blog on the Microsoft website, the figures were not showing. It was difficult to understand the article without having the figures. The figures were there in the article, but they were not getting loaded, which made the article obsolete."
"The support team is not competent or responsive."
"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."
"We should be able to use the product on devices like Apple, Linux, etc."
"For Microsoft Defender XDR, there is currently no ability to reset passwords for on-premises accounts, which is a key challenge."
"This solution could be improved if it included features such as those offered by Malwarebytes."
"There are a few technical issues with Defender XDR that can be improved. Sometimes, the endpoint devices are not reporting properly to the Defender 365 portal. When you're getting all the information from the Microsoft portal, the devices are sometimes not in sync. We have hundreds of endpoint devices, some needing to be onboarded again."
"Comodo includes a firewall and antivirus in one solution. I also like the ability to remotely manage update packages on your systems. Comodo can even find a lost device and secure it remotely."
 

Pricing and Cost Advice

"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"It is cost-effective compared to similar solutions. It fits for the small businesses through to the big businesses."
"Very costly product."
"The return on investment is from the user side because we have seen the performance of it increase the delivery time of the product if we are using too many web-based and on-premise applications. In indirect ways, we saw the return of investment in terms of performance and user satisfaction increase."
"The pricing is okay, although direct support can be expensive."
"Our customers have expressed that the price is high."
"It has reasonable pricing for the use cases it provides to the company."
"I am using the Community edition."
"The price of the solution is high compared to others and we have lost some customers because of it."
"It has consistently offered highly appealing academic pricing, with distinct rates for higher education and general educational purposes."
"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."
"Microsoft Defender XDR is already included in our Office 365 licensing. It is better because we're saving money by using it."
"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."
"It is fairly priced because we get complete integrated services with the E5 license."
"On average, we pay around 55 euros per user for the services and features we receive."
"It is 15 dollars per server per month. It is worth it, but it can be costly. It depends on the company's size."
