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

"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."
"They have a new GUI which is just fantastic."
"Cortex is the best tool for endpoint detection, and I have used it to verify hashes or domains to identify malicious activity, trigger playbooks that automate and gather endpoint logs, block malicious processes, and update incident tickets, showcasing end-to-end processes with automation in investigation and reducing the analysis workflow."
"Palo Alto is one of the tech vendors that always provides top-of-the-line products."
"I don't have to do much monitoring with it; I don't have to have anybody manually looking at this, it gives us reports, and it lets us know if something needs to be addressed, and we can easily address it."
"One of the things that I enjoy the most is using policy extensions. It's like having host firewalls to control USB connections. I think it's a wonderful tool to restrict use when connecting to our computers. Another important tool is Home Insights. That is an add-on to the Cortex solution. I like that because we can see all the vulnerabilities in the environment and control what assets are connected to our network."
"Technical support is the best in class, in my opinion, because they have invested heavily in research and development."
"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"Its most valuable feature is its ability to identify malicious connected IPs from outside and the attacks that get through to the inside."
"Ability to see events and exactly what traffic or website the device had tried to connect to that raised the alert or issue."
"The Enterprise Immune System, Cyber Artificial Intelligence Analyst, and Antigena technology are all very useful aspects of the product."
"The NDR is good in their solution and they have NTG for email."
"It has helped the organization to detect any malware affecting the machines...The network monitoring and the email monitoring features are very valuable for us."
"The product can scale."
"In terms of features, the data or information they collect and unsupervised machine learning are very valuable. Its unsupervised machine learning has reduced our team's effort. Both Darktrace and Vectra work on unsupervised machine learning that learns the behavior or develops a profile on its own, which allows our security team to do some other tasks rather than spending time on Darktrace or Vectra. Because of unsupervised machine learning, its detection capability is quite good. Along with that, if we utilize the integration feature properly, the automated incident response capability of Darktrace is quite useful."
"Darktrace played an important role in the security detection strategy by reducing the time lost in detecting, analyzing, and incident resolving."
"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

"The main issue I could point out is the offline agents and the way that it is missing."
"Cortex XDR should have a lightweight agent, and the agent size should not be heavy."
"Palo Alto Networks Cortex XDR does not detect malicious activity like in other anti-virus solutions like Trend Micro and Windows with Cisco."
"The downsides of Cortex XDR by Palo Alto Networks are that in many incidents, when I enter the causality chain, there are numerous logs."
"I would like to see improvement in the tool's user interface, particularly in the area of managing alerts and providing more reporting capabilities."
"Cortex XDR could improve its sales support team, including better commission structures and referral programs."
"The solution eats memory of the computer, unlike anything I've ever seen."
"Cortex XDR by Palo Alto Networks could improve by offering remote management. It would be useful to look at the client's issue to fix it."
"There are still some issues with the network capturing or blocking traffic even after implementing exceptions. It requires more learning in this area."
"Pricing bothers me and this is one of the major factors when choosing a solution."
"One thing that I would like to look at going forward is to have a fully automated network infrastructure that is monitored automatically real-time, and that gives me this kind of capability where I would be able to look at my network at any given time and see the state of my network. With Darktrace, at the moment, I have to almost put in a date and tell them that want you to give me data from this date to this date. I don't want that. I want a fast solution in which it doesn't matter when I log into the application. Whenever I log in, I must be able to see my network and run a report. In other words, if I go in now and I say, "Give me a full report of what happened today, it must be able to give me that. It mustn't just be limited to a seven-day period, for argument's sake. It must be able to give me real-time and day-to-day tracking of what has happened within my network."
"It can have more integration with orchestration or event management solutions. They can provide more knowledge or research information for analysts for investigating cases and detecting anomalies in networks."
"The solution can improve the reporting. Currently, it only runs weekly and the reporting is complex."
"I did not use the AI features because they should make it more user-friendly which would be a benefit. Additionally, the solution could integrate with more SIEM or SOAR tools."
"The program is quite expensive."
"The pricing is based on the number of endpoints, so the program is rather expensive."
"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

"It has a yearly renewal."
"I don't recall what the cost was, but it wasn't really that expensive."
"Licensing for Palo Alto Networks Cortex XDR can be costly, especially when it comes to a hundred users. A license is required for each user, and the subscription must be renewed on a yearly basis."
"This is an expensive solution."
"The price is on the higher side, but it's okay."
"Cortex XDR’s pricing is very reasonable."
"I don't have any issues with the pricing. We are satisfied with the price."
"The price of the solution could be reduced. I have customers that have voiced that the solution is good for the value but if I want to sell more of the solution the price reduction would help."
"The product is expensive."
"It is pretty expensive, but it is worth it. Its licensing is yearly."
"It is inexpensive considering what it can do and the competition."
"The pricing is a little high compared to the competition."
"It is expensive."
"It is a very expensive product."
"Darktrace is expensive. You can pay for the license yearly."
"This solution is expensive."
"It’s a single license platform."
