Senior Process Expert at A.P. Moller - Maersk
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.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly
In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"The normal protection was really effective, and we detected situations that if we didn't have Cortex XDR by Palo Alto Networks, it's highly likely that we would have been affected, but it protected the infrastructure."
"We switched because there were a lot of added features with Palo Alto that Check Point didn't have, and it was an upgrade for us."
"In one single alert, we are getting the network telemetry, endpoint telemetry, email security telemetry, and proxy telemetry all in one single ticket, making it very easy."
"Cortex XDR by Palo Alto Networks's ability to block sophisticated threats in real time is quite good and is on par with SentinelOne's."
"Technical support is the best in class, in my opinion, because they have invested heavily in research and development."
"The tool is designed to scale for large enterprises and handle large volumes of data."
"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"The dashboard is customizable."
"It is a stable solution."
"Darktrace is a good product and it can be implemented on premises."
"The Antigena feature is very useful."
"The most valuable feature of Darktrace and the most valuable feature is the artificial intelligence module because that is the tool that determines automatically if there is any risk or not in the network."
"Darktrace has helped our organization be secure from network spam and attacks."
"The autonomous response is also highly designed in Darktrace."
"I like the Antigena feature in Darktrace, as it offers immediate response and is helpful."
"While it is complex, and difficult to use, once you understand the correct way to use it, it's a very good platform."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"In general, the price could be more competitive."
"A better pricing plan would make this product more competitive."
"Limited remote connection."
"When it comes to malware files, it should be a little quick because, at times, it would give a wrong result in the sense of what it might be on malware, even if it still might be a normal one."
"To jump from the partner to Palo Alto directly was challenging."
"The GUI could be improved."
"Traps doesn't work with McAfee. You need to remove McAfee to install Traps. This is very common, and its nothing that should be an issue. Some antivirus engines recognize Traps as an threat component, so maybe they need to shake hands somewhere."
"I would rate it an 8 rather than a 10 mainly because there is still room to improve the user experience around complex investigations, including alert tuning and third-party integration."
"They just need to work on their price. In terms of features, we are trying to understand all the features that we have. We're still exploring everything that we have so that we can fully utilize it. At this point in time, it is not about the features. It is more about utilization. We're just trying to utilize everything to full capacity."
"A reporting portal could be a great addition to help customize reports."
"The dashboard and reporting for this solution could be improved as it is currently complex. The GUI for this solution could also be improved."
"I feel that Darktrace could be improved, particularly in the support aspect which is currently very poor. We need to chase Darktrace instead of them being proactive with us."
"The one downside is the pricing, which is quite high."
"There is no dedicated salesperson in Egypt, and having one would help to improve focus on this market."
"Darktrace would tell you, for example, if there was a ransomware attack, but it wouldn't stop the attack."
"They just need to make it a little bit more accurate as far as their alerts are concerned. It does generate some false positives that you have to tune. You have to do a lot of tuning when you first get it because of the false positives, but once it is all tuned up and ready to go, it will do its thing from there."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Our license will require renewal in August, after which the maintenance will continue as usual."
"The cost of Cortex XDR by Palo Alto Networks is $55 to $90 USD per endpoint per month."

"The pricing is okay, although direct support can be expensive."
"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."

"In the ballpark, we're talking about $30K, $50K, and up. It can even be as much as $50K or $100K."
"If you consider the features and the cost of market leaders, we are satisfied with the pricing."

"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"The tool's pricing is costly."
"The cost of the solution is expensive for smaller businesses. They will not be able to afford it or might not need this type of security solution."
"It’s a single license platform."
