VPN Setup and Usage Guide
IT & Security Network & Access Last reviewed: 2025-11-15 Owner: Infrastructure Services
Overview
All employees requiring remote access to Global Bank's internal network must use the approved Virtual Private Network (VPN) solution. The corporate VPN encrypts all traffic between your device and the bank's data centre, ensuring that sensitive financial data and internal communications remain protected in transit.
Policy Reference: IT-NET-001
Applies To: All employees, contractors, and third-party vendors with remote access privileges
Prerequisites

- Active Multi-Factor Authentication (MFA) enrolment (see MFA Guide, IT-NET-004)
- An active network account provisioned by IT Operations
- Approval from your line manager for remote working arrangements
Supported VPN Client
Global Bank uses CiscoSecure Connect v4.2 as the sole approved VPN client. No other VPN software is permitted on corporate or BYOD devices.
