Rock Tech Limited designs, deploys, and hardens end-to-end enterprise infrastructure. From active/active firewall transit cores and SD-WAN overlays to multi-cloud connectors and VMware micro-segmentation, we engineer zero-trust resilience into every layer.
Enterprise Infrastructure & Multi-Cloud Topology
Our unified architectural reference model integrating Public Cloud, On-Prem Data Center, Enterprise Branch Offices, and Active/Active SD-WAN Security Core.
Topology Breakdown & Engineering Scope
How Rock Tech Limited implements and manages each segment of your global infrastructure.
Centralized orchestration hub providing active/active Next-Gen Firewall (NGFW) threat inspection, IPS/IDS, dynamic path selection, and encrypted overlay tunnels across all enterprise endpoints.
Deployment of high-availability WAN controllers, SASE integration, and zero-downtime failover routing.
DirectConnect and ExpressRoute dedicated circuit termination for AWS VPCs, Azure VNETs, and GCP VPCs with automated Cloud SD-WAN gateways and continuous telemetry.
Infrastructure-as-Code (Terraform) landing zones, cloud firewall clusters, and multi-tenant isolation.
High-density compute with VMware Clusters, VXLAN fabric spine-leaf switches, internal perimeter firewalls, and hypervisor-level micro-segmentation.
Design and integration of VMware NSX, SAN storage fabrics, and automated disaster recovery execution.
Branch SD-WAN CPEs, local next-generation firewalls, secure Wi-Fi access point deployment, and localized VLAN identity segmentation.
Zero-touch provisioning (ZTP) deployment, 802.1X NAC implementation, and branch edge defense.
Distributed enforcement points verifying identity, device compliance, and strict least-privilege policies before allowing access across encrypted tunnels.
ZTNA posture assessment, policy ruleset engineering, and continuous vulnerability management.
Optimized SaaS application traffic routing directly through Cloud Access Security Brokers (CASB) and Secure Web Gateways (SWG) to minimize latency.
CASB policy definition, SaaS path optimization, and SSL/TLS inspection deployment.
