High Availability and Resilience

One failure does not cut off your remote team.

VPN infrastructure deployed with redundancy and automatic failover. A hardware failure or ISP outage triggers automatic recovery in under 30 seconds. No user action required.

What We Deliver

High availability capabilities.

Redundant Gateway Infrastructure

VPN gateways deployed in active-active or active-passive configuration. No single point of failure in the remote access path. Hardware failure does not interrupt connected sessions or prevent new connections.

Automatic Failover

Failover between VPN gateways happens automatically without user action. Clients reconnect to the available gateway within seconds. Staff experience a brief reconnection, not a prolonged outage.

Multi-Site Deployment

For organisations with multiple offices, VPN gateways deployed at each site. Remote staff connect to the nearest available gateway. Site failure does not affect remote access to other sites.

Internet Connection Redundancy

VPN infrastructure connected to multiple internet providers where required. ISP failure triggers automatic failover to the secondary connection. Remote access maintained even during primary ISP outages.

99.9% Uptime SLA

VPN infrastructure backed by a 99.9% uptime service level agreement. Downtime measured and reported monthly. SLA credits applied automatically if targets are missed. Performance data available on request.

Capacity Planning and Scaling

VPN infrastructure sized for your current user count with headroom for growth. Capacity reviewed quarterly. Scaling triggered before performance degrades. No manual intervention required for routine growth.

How It Works

From single point of failure to resilient remote access.

01

Resilience Requirements Assessment

We review your remote working dependency, identify single points of failure in your current setup, and define the uptime and recovery time objectives your business requires from remote access infrastructure.

02

High Availability Architecture Design

Redundant VPN architecture designed for your infrastructure. Gateway placement determined. Failover configuration planned. Internet redundancy requirements assessed. Capacity modelled against current and projected user counts.

03

Infrastructure Deployment

Redundant VPN gateways deployed and configured. Failover rules set and tested. Internet redundancy configured where required. Load balancing applied for active-active deployments.

04

Failover Testing

Failover scenarios tested with live traffic. Primary gateway failure simulated. Failover time measured and confirmed against SLA targets. Client reconnection behaviour validated across all device types.

05

Monitoring and Alerting Setup

Infrastructure health monitoring configured. Alerts sent to your IT team if a gateway becomes degraded before failover is required. Capacity alerts triggered when utilisation approaches limits.

06

Ongoing Management and Reporting

Infrastructure health monitored continuously. Monthly uptime reports provided against SLA targets. Capacity reviews conducted quarterly. Firmware and security patches applied during maintenance windows.

UK Case Studies

Resilient VPN infrastructure across the UK.

Financial Services Firm, London

Challenge: A London financial services firm had a single VPN gateway with no redundancy. A hardware failure during a busy period left all remote staff unable to access systems for four hours. The incident cost the firm a significant amount in lost productivity.

Outcome: Active-passive VPN gateway pair deployed. Failover tested and confirmed at under 30 seconds. No further unplanned remote access outages in the 18 months following deployment.

Logistics Company, Birmingham

Challenge: A Birmingham logistics company had remote staff across the UK who depended on VPN access to their transport management system. A single ISP outage at their head office cut off all remote access for half a day.

Outcome: Dual ISP connection deployed at head office. VPN gateway configured to failover between ISPs automatically. Subsequent ISP outage caused zero remote access disruption.

Healthcare Provider, Manchester

Challenge: A Manchester healthcare provider needed to demonstrate to their NHS Digital assessment that their remote access infrastructure had sufficient resilience to meet NHS data security requirements for critical system availability.

Outcome: Redundant VPN infrastructure deployed with documented failover procedures and tested recovery times. NHS Digital assessment passed. Uptime SLA evidence provided for ongoing compliance reporting.
