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.

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

"Since they've done their most recent update, the ease to isolate endpoints is valuable. If we find one where there is a virus on it, we can easily isolate it. We don't even have to contact the user. We don't have to manually take them off the network. We can easily isolate them."

"The anti-exploit is impenetrable. We chose Traps because it is the only product that we were not able to get anything past."

"We can visualize and control the activities in the environment from anywhere."

"The solution doesn't need a high level of technical training."

"There has been a significant reduction of approximately 70% to 80% in our internal MTTR and MTTD metrics, now around five to eight minutes whereas previously it was hours, which has helped tremendously."

"The product's initial setup phase is very easy."

"Cortex XDR by Palo Alto Networks saves time in various ways, although the user interface is fairly standard."

"It blocks malicious files. It prevents attacks. It doesn't require many updates, it's a very light application."

More Cortex XDR by Palo Alto Networks pros

"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."

"I think this has a lot of valuable functions that really could be leveraged quite nicely."

"This solution can completely detect and prevent incidents on your network."

"AlienVault provided the best bang for buck."

"AlienVault's reporting is good. I like that vulnerability assessment is part of the solution, and the UI is intuitive. Also, the overhead is low, which is to say we don't need a dedicated SOC team to manage and analyze things constantly. We're a small company that doesn't have those resources."

"The other big selling feature for us was its integration capabilities with all the other security-based products."

"The most valuable features of AT&T AlienVault USM are the ease of management and knowledge of what is on the network of my customers. It's easy to understand the problems, and management our alarms and events."

"AlienVault has helped us in improving our visualization and incident response during cybersecurity situations."

"It allows for a lot of out-of-the-box features: vuln scanning, HIDS/HIPS, and IDS."

More USM Anywhere pros

Cons

"The only issues that we have are, one the cost, two the dashboard is not very intuitive, even though you can drill down within the dashboard, we usually have to gather information from other sources to determine locations and if its a false positive."

"I have run into some detection issues with Cortex XDR. It needs to be better at detection of internal attacks."

"Cortex XDR should have a lightweight agent, and the agent size should not be heavy."

"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."

"There is a severe gap in functionality between Windows, Linux, and Mac versions."

"The connection to the internet has not performed as expected."

"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."

"It would be good to have a better way to search for a file within the UI."

More Cortex XDR by Palo Alto Networks cons

"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."

"There are scalability issues due to a 60 TB limit, which restricts its use for large customers like banks."

"The only room for improvement I can mention is the initial installation procedures. I found that the online installation instructions for the product were missing important details, they lacked necessary steps."

"Different functions to customize reports should be added."

"It would be great if there was a feature to add in watch lists, like McAfee or QRadar have -- to keep track of IPs, domain, etc. that I have identified as being malicious."

"The search capabilities are not optimal and are going to be optimized in the next versions."

"I would say the menus could use some tweaking and custom rule creation could be made simpler."

"The reporting aspect could be improved. While there are a lot of different options available, there are still pieces which are missing."

"Its reporting tools need improvements. It would be good if they can provide integration with other ticketing systems. Currently, we only have integration with Slack and Jira. It is also a bit slow, and its replication engine can be improved."

Pricing and Cost Advice

"If one wishes to work with another team or large number of users at a future point, he must purchase a license for them."

"The pricing is a little bit on the expensive side."

"This is an expensive solution."

"The price of the product is not very economical."

"The pricing seems fair, and I do like the licensing model. You use wherever they are, and it is elastic."

"It is "expensive" and flexible."

"Cortex XDR by Palo Alto Networks is an expensive solution."

"It's way too expensive, but security is expensive. You pay for your licensing, and then you pay for someone to monitor the stuff."

More Cortex XDR by Palo Alto Networks pricing and cost advice

"It’s a single license platform."

"They are a little more expensive than Microsoft."

"We checked out several competitors. For what it can do and the cost, it was the best option!"

"It has good pricing."

"I rate the price of AT&T AlienVault USM a four out of five."

"The ROI is quite good."

"The price for this solution is very good, but since the features do not work the price is expensive."

"It allows you to do a lot with a small price tag... The pricing is the best on the market."

"The licensing fees are dependent on usage."
