Taken as a whole, Shah argues that by doing all of this in the firewall, customers stand to eliminate the complexity of managing multiple platforms to achieve a zero-trust architecture. 'It's high time to using microsegmentation in datacenters, and the firewall remains the central part of that,' he said. Meanwhile microsegmentation – a technology often used in zero-trust architectures to ensure only those workloads that are supposed to talk to each other can – provides an avenue for securing application-to-application traffic within the datacenter. While zero-trust network access is largely seen as a replacement for VPNs for remote access, Shah believes the technology can be applied to secure datacenter-to-datacenter traffic as well. Healthcare is one market in which Shah sees strong demand for this class of high-performance firewalls, because they're often saddled with large quantities of highly sensitive data that may need to be moved between datacenters or the cloud to perform machine-learning tasks. Or as he put it, clients 'building hyperscale datacenters for specific applications that need to compliance and performance requirements.' It's aimed at customers dealing with large flows of sensitive data within and between private and cloud datacenters.

The 3700F isn't for everyone, yet, Shah admitted. Though the firewall does lose out on raw capacity – coming in at 600Gbit/sec. This week, the security vendor upped the ante with the FortiGate 3700F, which packs multiple 400Gbit/sec ports into an even smaller 2U chassis.

Fortinet's security appliances hit by remote code execution vulnerability.

Nvidia adds Arm support to its 5G kit, and a 16-core BlueField DPU to speed up edge, HPC.

Nvidia says its SmartNICs sizzled to world record storage schlepping status.

Fortinet says it's all about the security ASICs.

These firewalls specifically targeted high-performance datacenter and hyperscale customers. The company's NP7 ASIC-based FortiGate 4200F and later 4400F firewalls, introduced in late 2020, brought 100Gbit/sec interfaces and north of 1.15Tbit/sec of firewall capacity, in the case of the latter, to a 4U chassis. Fortinet is no stranger to this challenge.
