Featured Reviews

AKASH MAJUMDER - PeerSpot reviewer
Incident response times have significantly reduced with efficient device integration and log parsing capabilities
Cortex XSIAM needs improvements in terms of data onboarding, parsers, and third-party integration supports. Additionally, a future update request is to enable tagging of endpoints in groups, similar to a feature available in Cortex XDR. The AI analytics need fine-tuning because some use cases are not working from my side.
MOTASHIM Al Razi - PeerSpot reviewer
It is a stable solution, but they should make the user interface easier to understand
The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.

Quotes from Members

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

Pros

"The automation capabilities significantly improve response times by allowing us to respond to incidents from a single dashboard rather than navigating multiple dashboards."
"The most valuable aspect is that Cortex XSIAM doesn't generate excessive alerts, refines all search results effectively, and filters out incidents where SOC intervention isn't necessary, allowing engineers to focus only on what matters."
"The flexibility for creating manual workflows stands out."
"The flexibility for creating manual workflows stands out."
"One of the valued aspects of the product is its use of artificial intelligence to detect security vulnerabilities."
"The most valuable features of Cortex XSIAM are the machine learning used to identify threats, the complexity of the environment of products, and efficiency."
"I would give Cortex XSIAM a rating of ten out of ten."
"It does a better job of identifying anomalies that are more likely to be incidents of compromise without as many false positives or false negatives."
"It's quite economical compared to other solutions in the market."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"Their technical support responds quickly and are knowledgable."
"I can have enterprise security, email security, next generation firewall security log, HIDS and NIDS logs, etc. all on the same dashboard. It makes it easy to pinpoint or correlate our server to this. I can find out if there is lateral movement. This is the biggest advantage of this solution."
"The most valuable feature of RSA NetWitness Logs and Packets are the alerts and correlations tools."
"The most valuable features are the packet decoder, log decoder, and concentrator."
"It's fully scalable. There is no limit. Of course, the license limits per day the number of terabytes. In my opinion, it's very flexible."
"The most valuable feature is the hunting ability to work in a CERT."
 

Cons

"I would rate the overall stability a six or seven, as we have only used it for a few months and need a year of experience to provide a full assessment."
"The standard integrations are very limited, and the integrations available are not listed in the marketplace. Obtaining validation for integrations from Palo Alto takes around eight months, which is quite long."
"I am not sure if any improvements are needed right now."
"Cortex could improve the detection and online resolution of security vulnerabilities."
"The support could be a bit faster."
"The platform isn't very developer-friendly and it should provide more flexibility and ease."
"There is room for improvement in expanding integrations to include more cybersecurity solutions."
"It could provide more integration with a large variety of products."
"I believe that integrating the solution with other products such as Oracle would be beneficial."
"We have encountered issues with unresolved crashes."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"More customizability is required, which is something that they need to improve on."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"I'd like to see improvement in its ease of use. It's basically unusable. It's overly complex."
"Technical support could be improved."
 

Pricing and Cost Advice

"The solution is expensive compared to its competitors."
"Since Palo Alto is trying to get as many new customers as possible, they're offering very competitive pricing."
"The product cost could be considered value for money compared to other solutions in the market, though it is quite high."
"In terms of pricing, we found Cortex XSIAM to offer a very reasonable and competitive rate."
"The solution comes at a significant cost."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"It is cheap."
"Our license is for one year."
"Compared to the competition, the is price is not that high."
"We are on an annual license for the use of the solution."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"The product price was reasonable for my region and the market."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
