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

"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"Cortex XDR by Palo Alto Networks has accelerated the response time for my security team, so we have been able to resolve issues faster than usual."
"The most valuable aspect of Cortex XDR by Palo Alto Networks for me is its integration with AI detection, where we get to know the behavioral detection based on users, traffic patterns, and different services that we consume."
"The stability of this product is very good."
"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"Stability is one of the features we like the most."
"They have a new GUI which is just fantastic."
"The main benefit of using Cortex XDR by Palo Alto Networks while employing Palo Alto Firewall at the internet edge is that it improves security on our endpoint devices, integrating seamlessly with Palo Alto Firewalls to deliver comprehensive network, analyst, and security details all in a single dashboard, which allows us to manage everything from our network devices."
"It is really good; it has given us a view of our company and it has actually caught a couple of people that were doing data exfiltration and stealing data from our company, and we caught them doing it in the act in live time, which is just incredible."
"Because of all it does, Darktrace is a very good solution, and it doesn't take a lot of time to implement and to get results."
"They've worked hard to be the top security control in terms of AI and machine learning, and their product works well."
"Overall, this is a good product that seems to be working well."
"The scalability of Darktrace is very high."
"I have found the automation and AI features to be valuable. If someone were to come in to the office at midnight and log in, Darktrace would flag it."
"One thing I appreciate is Antigena Email, which is for email protection."
"I have found the most valuable features to be artificial intelligence for cybersecurity, advanced machine learning capabilities, enterprise Immune System, Antigena Network, and Antigena Email. The way the solution detects the threat over the network before it spreads is very good. It notifies you of what the threat is exactly doing and gives you all the details about the execution of that application that had created the threat over your network."
"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

"Product might have some bugs."
"Cortex XDR could be improved with more GUI features."
"Enhancing UI simplicity and playbook flexibility are areas that could benefit from more low-code automation options for smoother integrations."
"This product has not improved my organization - in fact, we are in the process of moving back to another product as a result of Cortex's horrible impact on system performance."
"Basically, they don't provide customer support tools just to investigate the logs."
"There are some false positives."
"A better pricing plan would make this product more competitive."
"Cortex XDR by Palo Alto Networks is not only pricey; it is extremely expensive."
"I think there is some MSSP missing."
"This product needs more in terms of prevention. The detection capabilities work well but once a threat has been detected, Darktrace should work to prevent it from doing anything malicious."
"In terms of improvements, fine-tuning is the area where we have to spend some time because it works on unsupervised machine learning."
"The cost of the solution is expensive for smaller businesses."
"Darktrace would tell you, for example, if there was a ransomware attack, but it wouldn't stop the attack."
"Updates keep coming, which is great, but I prefer a unified UI experience. The intelligence section and the incident view should be seamlessly connected in one view to avoid jumping between pages."
"If asked to rate Darktrace support on a scale from zero to ten where ten is the best, I would give them five points."
"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."
"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

"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."
"It's about $55 per license on a yearly basis."
"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."
"The price of the solution is high for the license and in general."
"This is an expensive solution."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"Cortex XDR’s pricing is very reasonable."
"It has a yearly renewal."
"Darktrace is quite an expensive solution."
"It is a very expensive product."
"The pricing is very flexible for Darktrace. Sometimes, a customer does not have the appropriate budget, but Darktrace can handle that. They offer monthly payments, so the customer can acquire the solution very easily."
"The pricing is quite high, estimated at around $350,000 per year."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"The solution is about $6,000 per quarter."
"Darktrace is expensive. You can pay for the license yearly."
"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."
