A firewall acts as a barrier between internal and external computers in a network, controlling the flow of information between the two. When a computer outside the firewall wishes to communicate with a computer inside, it must communicate with the firewall, which then passes the data to the internal computer. This two-step process helps protect Butterfield Group’s internal network from unauthorised access.

Security Audits

Butterfield Group is committed to ensuring our security measures are of the highest of standards. We have, therefore, employed an external auditing firm to perform regular security audits against of our infrastructure to ensure we are not exposed to new vulnerabilities in hardware and software.

Digital Certificates

To help ensure the security of your account information, we use a system involving Digital Identification Certificates from third-party providers of digital authentication products and services.
