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.

Centralized monitoring has improved threat visibility and reduced incident response time
In terms of valuable features in ESET EDR/XDR, we focus on endpoint device management as well as for the firewall team, including our log analysis and monitoring the firewall, which are three significant functions for us. ESET EDR/XDR has automated threat detection that gives us real-time incident alerts, and it helps us proactively receive and work on incidents that could have an impact. Regarding the usefulness of ESET EDR/XDR's behavior-based analysis in detecting potential breaches, we have identified some files or configuration files that should remain static, and if any changes occur without proper change management, we are able to identify those changes, including detecting zero-day attacks. The integration of threat intelligence feeds has helped our response strategies, as we are using Oracle OCA-based data analysis, and we have integrated it so that logs are forwarded to our SIEM, allowing us to analyze the data effectively. I evaluate the impact of centralized management on our security operations as very useful because it eliminates the need to log into individual systems to find sources, allowing us to identify all types of risks and vulnerabilities from a single desk.

Unified security monitoring has reduced alert fatigue and improves proactive threat hunting
I use real-time monitoring in ReliaQuest GreyMatter, which significantly improves my security posture. The unified interface helps reduce alert fatigue. I would estimate it saves around 20% in alert fatigue reduction. The automated threat hunting capabilities in ReliaQuest GreyMatter help me stay ahead of threats. The machine learning algorithm benefits my threat intelligence by providing deeper insights and predictions. I use various metrics to rate the success of the predictive threat intelligence in ReliaQuest GreyMatter.

Cons

"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"It is an enterprise-level solution. Its price could be less expensive."
"Although I would say this product is highly-rated, it could probably do more because nothing does everything that you want."
"Cortex XDR by Palo Alto Networks is a strong tool, but it is true that digesting information sometimes makes the tool go a little bit slower."
"Initially, we got to have a lot of false positives when we onboarded, but nowadays it's quite smooth."
"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."
"The MAC agent is not as robust feature-wise as the PC version."
"The solution could improve how it scours each website."
"ESET EDR_XDR needs to conduct more research and development and innovations in early detection of attacks."
"The memory and CPU footprint can affect performance. It sometimes slows down the CPU performance."
"Areas that have room for improvement include user interface and integration."
 

Pricing and Cost Advice

"The pricing is a little high. It is per user per year."
"Cortex XDR by Palo Alto Networks is an expensive solution."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"The solution is expensive. It's pricing is on a yearly-basis."

"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."
