Banks use isolation to secure old check printing systems
Banks continue to rely on legacy systems for printing checks because critical financial software and hardware are incompatible with modern operating systems. To secure these outdated but essential devices, security teams often use network isolation, restricting internet access and limiting exposure inside company networks. This approach protects against cyber threats when patching is not possible due to compatibility risks and the need to avoid downtime during check processing.
- Financial institutions use obsolete systems for check printing
- Patching is impossible due to outdated software dependencies
- Network isolation is used to limit attack surface
- Zero tolerance for downtime prevents system upgrades
