Cloud adoption is accelerating, but securing distributed workloads also introduces challenges around infrastructure efficiency, resource utilization, and operational complexity.

Virtual firewalls offer an opportunity to rethink how network security is deployed in modern cloud environments. By integrating security capabilities directly into virtualized and cloud infrastructure, organizations can build scalable security architectures while making more efficient use of compute, networking, and infrastructure resources.

In this session, we will explore how virtual firewalls contribute to sustainable cloud security, covering deployment models across public cloud and virtualization platforms, right-sizing firewall instances, optimizing resource consumption, and balancing security performance with infrastructure efficiency.

We will also discuss practical architectural considerations, including centralized versus distributed security enforcement, high availability, workload scaling, and the importance of selecting the right firewall capacity for different workloads.

Attendees will leave with practical insights into designing secure, scalable, and resource-efficient cloud network architectures that support both cybersecurity and sustainability objectives.
