WHY CHOOSE THIS PRODUCT?

• Organizations choose the A10 Thunder 5840 CFW when they require enterprise-scale security capacity without moving to more complex chassis-based architectures. The combination of 100 Gbps firewall throughput, 48×10GbE SFP+ connectivity, 128 million concurrent sessions, and dedicated SSL inspection acceleration provides a significant advantage over lower-capacity security appliances. For procurement teams planning firewall refresh projects, cloud expansion initiatives, or security infrastructure consolidation, the platform delivers strong ROI through higher port density, reduced operational complexity, and scalable performance. Its redundant power design, extensive VPN capabilities, and large session capacity also help support long-term business continuity, cybersecurity resilience, and infrastructure lifecycle planning.
