Case Study: Credit Bank Zagreb achieves Basel II compliance and secure banking transactions with Fortinet

Credit Bank Zagreb (Kreditna banka Zagreb d.d.) chooses Fortinet to secure its Banking Transactions

Credit Bank Zagreb, a mid-sized Croatian bank with 23 branches handling roughly 3.5 million domestic and 80,000 foreign transactions annually, needed to strengthen IT security under Basel II and counter a rising tide of sophisticated cyberattacks. The bank sought comprehensive, proactive controls for transaction and session monitoring, end-to-end traceability for Internet banking, and business continuity through disaster recovery sites.

Credit Bank Zagreb deployed a layered Fortinet solution—HA clusters of FortiGate appliances (200/300/80/50/40 series), BGP/OSPF routing, IPS and DoS protection, plus FortiGuard antivirus, web and email filtering—across its primary and backup sites and ATMs. The rollout improved manageability and reliability, met Basel II requirements, consolidated multiple security functions onto fewer devices, required minimal administration, and enabled the bank to expand security services further.
