Has improved real-time threat detection and unified cloud protection through AI and automation
Cortex Cloud by Palo Alto Networks is creating some confusion in terms of names because this is recent. They changed the names of the products and are now clarifying their offer. The family of the products is not easy to follow because it's very recent. Regarding the generative AI security tool, I know for sure it's Agentic. Based on my experience with Palo Alto, I can suggest what Cortex Cloud by Palo Alto Networks could make better or what additional functions could be added. This is the best tool in the market. It's not the time to tell what they could do better because it's a recent tool. The market is now adopting it. Our experience doesn't show that they need to do more.

Containerization has standardized deployments and drives faster, more reliable delivery
As Docker is already a very mature tool, there are areas where it can be improved based on real-world usage. One area I consider is the Windows container experience. The pain point here is that Windows containers are heavier and slower than Linux containers because I have worked in both environments and felt that Windows containers are heavier and slower than Linux containers. This also limits the ecosystem and tooling maturity compared to Linux containers. Improvements could include performance optimization and better parity with Linux container features. Apart from that, observability and debugging is another area. The pain point is the limited native metrics available and limited logging and tracing features. Improvements could include adding a good amount of metrics, logging, and tracing, as well as better built-in observability features and easier container introspection. Network complexity is also present. I face issues with Docker networking that can become confusing in complex setups, and debugging container-to-container issues is not always intuitive. Improvements can be made with simpler networking abstractions and better built-in troubleshooting tools. Docker is excellent for containerization and CI/CD, but it can be improved in areas of built-in security, network simplicity, and observability. These points should be kept in mind and worked on.

Quotes from Members

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

Pros

"I have absolutely seen improvements in our incident close rates, with mean time to detect and respond reduced significantly, sometimes by at least forty to fifty percent."
"I have seen several benefits from using Cortex Cloud by Palo Alto Networks: It was easy to use and easy to migrate from the IBM platform."
"Cortex Cloud by Palo Alto Networks has impacted our organization positively by keeping our machines secure and our team using the dashboard to find issues quickly."
"Overall, Cortex Cloud by Palo Alto Networks is a technically strong product, and I rate it ten out of ten."
"The AI and automation features in detecting and responding to high-risk threats are impressive; it's one of the best tools regarding AI technology and unifies security in one platform in real-time, improving vulnerability analysis, incident response, and compliance reporting."
"The most valuable feature is the simple containerization."
"I have seen end-to-end performance with Docker. It's a great tool, and it's the most popular container service in the market."
"The most valuable feature is that it is cost-saving."
"Docker is easy to understand and follow. It provides good scalability to the application."
"Kubernetes is the primary container orchestration tool I use with this solution. Docker provides a complete solution for deploying and managing workloads across multiple nodes. Container orchestration has significantly impacted my workload by automating tasks and streamlining operations. The availability of systems like Kubernetes is crucial for planning and managing complete clusters and computing environments. Every client's needs are different, and not one solution fits all."
"The lift and shift creates a lightweight image."
"The most valuable features of Docker are its security, detailed documentation, and ease of use, and the Docker Swarm is not as complex as Kubernetes."
"It is neat and very flexible."
 

Cons

"The pricing is high, making ROI challenging to justify, especially during transitions between solutions."
"Cortex Cloud by Palo Alto Networks is creating some confusion in terms of names because this is recent."
"Overall, I rate Cortex Cloud by Palo Alto Networks as an eight out of ten. I think that it could improve on price, as I know that the Google solution has the best price, and this is one of the conditions."
"Some aspects of the GUI can be confusing and make it difficult for me to find certain options or navigate where needed."
"Docker could improve by having security vulnerability reports."
"If you install Docker on a host, it creates its own firewalls. It can become an issue. Usually, when you want to install Docker, you need to restart the firewall or restart the active tables on the machine, but this is not the case with Kubernetes. It uses the default set up by the next administrator, but with Docker, you have to restart the firewall and restart Docker before the firewall on the system will be okay. If you do not the rules will not be created."
"Unfortunately, base images are not currently available."
"The runtime and security could improve in Docker. Security is paramount in the cloud and important."
"I want to see if new architectures have been incorporated in Docker or if we have to wait for another release."
"I think Docker can improve as it relates to overall stability."
"Docker needs to improve its pricing."
"There are elements of stability that are problematic. One of the most recent upgrades created a major incident on our cloud, whereby the containers were not restarting automatically."
