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.

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.

Endpoint monitoring has strengthened incident response and provides rapid isolation and forensics
Tanium provides an endpoint which is isolated from the network and environment. We can easily search its logs and history and connect remotely directly to that particular device which has been isolated from the network. We can search for the history and logs, including audit logs and event logs. The complete activity of the user or owner of the device is visible to us. We can see the artifacts of particular USB transfers internally for official use. We can not only connect remotely but also see the device status and how many failures have occurred within the network so far. We can see the IP address, how many times it has changed its IP address, and how many times it was connected to VPN or external VPN or internal VPN and what has been searched while on VPN. We can block the IOCs or IP addresses as well. We can block domains, hashes, SHA values, SHA-256, SHA-1, SHA-5 and MD5. Although I am not completely involved in the automation team, we do have that team and I have worked in some CERT recently. Tanium is more useful while we are in the CERT because most of the times when we are on high alert, Tanium does play a main role for that particular incident or any high case. Tanium is a simple tool and we can easily integrate it to many devices and it is a mandatory tool to secure an endpoint. It is mandatory to give any RDP connection and the tool should be present in the particular device. It is completely mandatory and it is in the policy as well.

Quotes from Members

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

Pros

"Cortex XDR by Palo Alto Networks has changed the way my security team detects, investigates, and responds to threats, as we are able to see the files, unwanted files, unsecured files, and unauthorized files, so we are quarantining them."
"Based on my experience, I would recommend Cortex XDR by Palo Alto Networks to other people."
"I've found the solution to be highly scalable for enterprises."
"It has pretty much everything we need and works well within the Palo Alto ecosystem."
"The user interface of the solution is sophisticated and straightforward."
"Palo Alto is the core of the security infrastructure in the environment."
"After deploying Traps, we saw the performance of the network improve by 65 to 70 percent."
"Palo Alto is the best security solution in the market."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"I like the tool's incident response and security patching."
"I would say Tanium is the best tool for vulnerability management."
"I find the inventory and compliance features of Tanium to be the most impressive."
"Tanium is stable and it is also lightweight."
"Tanium is highly scalable."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"When I push a quick update, it's done right away, and I can rescan immediately to confirm completion within minutes."
"The solution's technical support is very responsive."
 

Cons

"However, if you do not have Palo Alto in your environment, you are paying these additional services just for Cortex XDR by Palo Alto Networks, so it is not a cost-effective solution."
"In general, the price could be more competitive."
"The solution should add unwanted malicious hash values to a block list so that whenever the action is triggered, it will automatically prevent the malicious content."
"For working with the solution, you only really need a web browser, however, we've found that working on Chrome, for example, is horrible."
"On the pricing aspect, Cortex XDR by Palo Alto Networks needs to have a more reasonable rate, particularly for customers in Sri Lanka and Asian countries."
"The playbooks could be improved to include more functionalities or actions."
"I don't like that they have different types of licenses. For example, if users select a license, they think they will have all the platforms they need to improve their network or security. But after some time, Palo Alto Networks changed their licensing, and some of the features that, for example, were free at the beginning now have a cost. I think the integration can be improved. For example, a lot of tools are just integrated through APIs."
"In reporting they should have a customizable dashboard due to the fact that C-level people don't like reporting to the IT department. They prefer to have a real-time dashboard. That kind of dashboard needs to have various customizations."
"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."
"Tanium’s scalability could be improved."
"The solution can give a lot of false positives."
"Our biggest issue with the solution is its lack of mobility."
"There are downsides and drawbacks in Tanium, and there is room for improvement from my perspective."
"The solution lacks mobility."
"The solution needs to improve the reporting and tracking capabilities."
"In my opinion, sometimes it takes a long time to give solutions or resolve the issue."
"Tanium's limitations should be improved because although it is a great tool, it is limited to only a few classes during a session."
 

Pricing and Cost Advice

"The price was fine."
"Our license will require renewal in August, after which the maintenance will continue as usual."
"It has a yearly renewal."
"Cortex XDR by Palo Alto Networks is quite an expensive solution."
"It's about $55 per license on a yearly basis."
"I don't have any issues with the pricing. We are satisfied with the price."
"Cortex XDR’s pricing is very reasonable."
"I did PoCs on products called Cylance and CrowdStrike. Although, I consider these products and they were also good, when it come to cost and budgetary factors, Traps has been proven to be better than the other two products. It is quite cost-effective and delivers all the entire solution which we require."
"It’s a single license platform."
"The product's pricing differs from region to region depending on negotiations and the number of endpoints."
"It's an expensive solution. It would be nice if the cost were lower."
"It is higher than some competitors in the market."
"There is an annual license required to use this solution."
"Tanium is a more expensive solution in Latin America than some of the competitors, such as BigFix."
"The solution is expensive but it's a good investment."
"The solution offers value for money."
