2025-07-16

1. Latest updates on Huawei Firewall
AI firewall upgrade:
Huawei will release a new generation HiSecEngine USG12000 series firewall in 2023, equipped with its self-developed Ascend AI chip, claiming to improve threat detection efficiency by 80% and support deep parsing of encrypted traffic (such as TLS 1.3).
Keywords: AI driven, zero trust architecture, encrypted traffic analysis.

Cloud firewall cooperation:
Huawei has partnered with multiple cloud service providers (such as AWS and Azure) to promote the deployment of its cloud native firewalls (such as vFW) in multi cloud environments, supporting unified policy management.

2.Major security incidents and policies
Firewall vulnerability exposed:
In September 2023, firewalls from multiple vendors (including Huawei USG series) were exposed to Log4j vulnerability variant attacks, and vendors urgently released patches (Huawei SA number: HWPSIRT-2023-0815).

Upgraded international compliance requirements:
The EU's Cyber Resilience Act requires firewall manufacturers to provide security update support for more than 10 years, which affects the product lifecycle strategy of Huawei and other companies exporting to Europe

3. News from other manufacturers
Palo Alto: Released AIOps driven firewall policy auto optimization tool (AI Policy Assistant).
