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.

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 isn't too bad."
"The most valuable for us is the correlation feature."
"Cortex XDR by Palo Alto Networks should be a stable solution."
"The protection offered by this product is good, as is the endpoint reporting."
"Based on my experience with Cortex XDR by Palo Alto Networks, I highly recommend it due to its quick response to zero-day attacks and low utilization from end-user devices."
"I can highlight that we have not faced any security incidents with Cortex XDR by Palo Alto Networks, and even though our environment is quite dynamic, we have not faced any security incident with Cortex XDR by Palo Alto Networks until now."
"Being a cloud solution it is very flexible in serving internal and external connections and a broad range of devices."
"Palo Alto is the best security solution in the market."
"The AI-based pattern is the most valuable feature."
"DT console and alerting system allow getting detailed information about the behavior of users and malicious external or internal threats."
"I can rate Darktrace's technical support as one of the best products in the world."
"The platform has many modules, and each module examines a different situation in the behavior."
"Darktrace impacts my organization positively by providing us with a better understanding of abnormal activities detected among users."
"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."
"I am impressed with the product's ability to give insights into network traffic."
"Darktrace is extremely stable."
"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

"It would be better if they could educate the customers more. Some sort of seminars and roadshows will help educate the customers and show what the product can do. The price could be better. It would also help if they had a team for deployment and support."
"The deployment is pretty hard."
"Cortex XDR is trickier to configure than other Palo Alto products. This is one area where we are not so satisfied."
"The product's pricing needs improvement. They could provide more discounts. Additionally, the dashboard and control panel could be enhanced."
"There are some default policies which sometimes affect our applications and cause them to run around."
"I feel that it should not be a licensed activity because a feature should allow us to see applications running on end devices."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"The price could be a little lower."
"Its threat analyzer could be better. It should also have agents."
"I would like to see some additional enhancements."
"The solution's user interface and stability could be improved."
"It is very expensive."
"The cost of the solution is quite high."
"Although we haven't detected any network threats since implementing Darktrace, we are unsure of its efficacy. It would be beneficial if the solution could offer additional details to the user regarding any potential or prevented threats. Additionally, there could be better search tools and integration."
"Darktrace could improve its features, such as monitoring and detecting ransomware."
"The pricing needs improvement."
"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

"This is an expensive solution."
"The price of the product is not very economical."
"Traps pays for itself within the first 16 months of a three-year subscription. This is attributed to OPEX savings, as security teams spent less time trying to identify and isolate malware for analysis as a result of a reduction in malware incidents, false positives, and breach avoidance."
"We didn't have to pay any additional fee for the cloud instance. It just came with the renewal, which was nice."
"Very costly product."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"I don't like that they have different types of licenses."
"When we first bought it, it was a bit expensive, but it was worth it. The licensing was straightforward."
"It was $3,600 a month or $2,000 plus or so. I am not sure. Its licensing is pretty simple."
"The pricing is subscription-based and it is high."
"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."
"The pricing is reasonable."
"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."
"It is inexpensive considering what it can do and the competition."
"They are too expensive compared with other vendors."
"I'm unfamiliar with the exact cost, but we have a yearly license and had to pay for Darktrace's services before the deployment. The product is very expensive, so some organizations can't afford to pay the total amount directly, meaning they often seek a partner or pay in installments, which increases the price more."
"It’s a single license platform."
