Case Study: Bangladesh Infrastructure Finance Fund Limited (BIFFL) achieves gigabit‑speed distributed network security and reduced cyberattack mitigation time with SonicWall High‑End Firewalls

Biffl Secures Distributed Financial Network At Gigabit Speeds

Bangladesh Infrastructure Finance Fund Limited (BIFFL), a government-owned non‑banking financial institution, faced the challenge of protecting a distributed network that supports extensive inbound/outbound web services from unauthorized users, hackers, ransomware and zero‑day threats, while securing interbranch connectivity over the public cloud and blocking unapproved websites. To address these needs, BIFFL turned to SonicWall, selecting SonicWall High‑End Series Firewalls.

SonicWall deployed its High‑End Series with Reassembly Free Deep Packet Inspection (RFDPI) and a massively multi‑core architecture to deliver multi‑gigabit application control, intrusion prevention, TLS/SSL decryption and URL inspection. SonicWall’s solution immediately reduced staff time spent mitigating cyberattacks, provided actionable dashboards and reports to curb inappropriate browsing, and let BIFFL control and monitor security from a single core firewall—cutting time spent on malware and bandwidth issues while delivering easy, affordable, reliable protection.
