Business Challenge
The client faced significant challenges with their existing perimeter security setup:
- Legacy firewall platform with limited throughput and end-of-support hardware.
- No HA configuration, leading to downtime during outages or upgrades.
- Frequent internet disconnections due to reliance on a single ISP.
- Growing requirement for higher bandwidth and security visibility to support digital government services.
Solution Delivered
BizCloud executed a seamless firewall migration and redundancy project with minimal downtime:
1. Assessment & Design
- Audited existing firewall rules, VPNs, NAT policies, and traffic flows.
- Designed next-generation firewall architecture with HA (active-passive) for core security.
- Planned multi-ISP internet bonding to distribute traffic and ensure failover.
2. Firewall Migration
- Migrated policies and NAT rules to the new platform with optimized rule base.
- Configured intrusion prevention, anti-malware, content filtering, and SSL inspection.
- Implemented site-to-site and remote-access VPNs.
-
3. High Availability (HA)
- Deployed firewalls in active-passive HA pair with state synchronization.
- Conducted failover testing to validate resilience.
4. Internet Bonding
- Integrated multiple ISPs using link bonding/load balancing.
- Configured automatic failover to backup links in case of primary ISP outage.
- Optimized routing to maximize throughput across bonded connections.
5. Testing & Knowledge Transfer
- Performed penetration tests and UAT to confirm functionality.
- Trained internal IT/security team on monitoring, reporting, and failover management.
Key Features Implemented
- ·Next-Generation Firewalls with HA pair.
- Multiple ISP Internet Bonding for uninterrupted connectivity.
- Advanced Security Policies (IPS, AV, URL/content filtering).
- Secure VPNs for branch and remote access.
- Optimized & Documented Firewall Rule Base.
Results & Benefits
- Zero downtime migration with successful cutover.
- Achieved 99.99% network uptime through HA and ISP bonding.
- Improved performance and bandwidth utilization across services.
- Enhanced cybersecurity posture with next-gen firewall features.
- Reduced risk of outages and improved business continuity for government operations.
