Firewall security for financial services
Banks, fintechs and insurers run some of the most heavily regulated networks in the world. FirewallScan keeps your FortiGate rule base least-privilege, segmented and audit-ready.
The firewall challenges financial services face
Financial networks are large, segmented and constantly changing. Mergers, new products and legacy systems leave behind layers of firewall rules that few people fully understand — and that almost nobody has time to review end to end.
The result is rule sprawl, overly permissive access between zones, and exceptions that were meant to be temporary. In an industry that is a prime target for attackers, every one of those is a liability.
- Decades of accumulated rules from systems, mergers and projects
- Strict segmentation requirements between card, core and corporate zones
- Heavy audit burden across multiple overlapping regulations
- Low tolerance for downtime, so risky rules are rarely cleaned up
Compliance pressure from every direction
Financial services firms answer to multiple frameworks at once, and firewall rule review is a recurring control across all of them.
PCI DSS
Requires documented firewall rule reviews at least every six months and strict segmentation of the cardholder data environment.
DORA & NIS2
EU financial entities must demonstrate strong network security and operational resilience, including controlled and reviewed configurations.
ISO 27001 & SOC 2
Expect evidence that network controls are reviewed regularly and that access follows least privilege.
