Endpoint Detection and Response (EDR) technologies provide comprehensive visibility and real-time threat prevention directly on endpoint devices. EDR continuously monitors process activities, file executions, and system calls to detect malware, suspicious behaviors, and zero-day threats at the source. Palo Alto Networks’ Cortex XDR platform exemplifies this by correlating endpoint telemetry with network and cloud data to provide a holistic defense against attacks. Operating locally on endpoints allows EDR to prevent lateral movement and respond to threats quickly, filling security gaps that network-centric tools alone cannot address. This endpoint-level insight is critical to identifying sophisticated threats that initiate or manifest on user devices.

According to the NIST definition, cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction1. One of the essential characteristics of cloud computing is on-demand self-service, which means that users can request and obtain computing resources as needed, without requiring human intervention from the service provider2. On-demand network services are an example of this characteristic, as they allow users to access network resources such as bandwidth, routing, firewall, or load balancing, on demand and in a scalable manner3. References:

 A routed protocol is a protocol by which data can be routed. It provides appropriate addressing information in its internet layer or network layer to allow a packet to be forwarded from one network to another network. Examples of routed protocols are the Internet Protocol (IP) and Internetwork Packet Exchange (IPX). IP is the most widely used routed protocol on the Internet and other networks. It assigns a unique logical address to each device and enables data to be fragmented, reassembled, and routed across multiple networks. References:

To deliver secure east-west flows and secure Kubernetes workloads in a public cloud environment, you have two deployment options available: VM-Series and CN-Series.

VM-Series is a virtualized form factor of the Palo Alto Networks next-generation firewall that can be deployed in public cloud platforms such as AWS, Azure, Google Cloud, and Oracle Cloud. VM-Series provides comprehensive network security and threat prevention capabilities for protecting your cloud workloads and applications from cyberattacks. VM-Series can also integrate with native cloud services and third-party tools to enable automation, orchestration, and visibility across your cloud environment. VM-Series supports various deployment scenarios, such as securing internet-facing applications, protecting hybrid connectivity, segmenting internal networks, and enabling secure DevOps12.

CN-Series is a containerized form factor of the Palo Alto Networks next-generation firewall that can be deployed in Kubernetes environments. CN-Series provides granular network security and threat prevention capabilities for protecting your Kubernetes pods and namespaces from cyberattacks. CN-Series can also integrate with Kubernetes network plugins and services to enable dynamic policy enforcement, service discovery, and visibility across your Kubernetes clusters. CN-Series supports various deployment scenarios, such as securing ingress and egress traffic, enforcing microsegmentation, and enabling secure DevSecOps34.
