Secure VPN connectivity
Purpose-built for privacy and data sovereignty.
HiTechCloud VPN Site-to-Site lets businesses create a private connectivity layer between on-premises and cloud, control traffic routing, protect sensitive data and operate distributed infrastructure as a single unified network.
Key capabilities
An encrypted backbone for distributed infrastructure.
Create a highly secure private link between offices, data centers and cloud VPCs, with monitoring, routing and flexible scaling.
Multipoint connectivity
Connect multiple geographic locations at once — branch offices, remote data centers and multi-region VPCs — within a single secure architecture.
Seamless hybrid cloud integration
Extend your on-premises data center into the cloud so on-premises resources and the VPC communicate as if on the same private network.
Automated status monitoring
Continuously monitors VPN tunnel status, helping detect incidents early and keep distributed systems reliably connected.
Fine-grained routing control
Define exactly which traffic segments may traverse the VPN using route tables, keeping systems separated and access policy tightly scoped.
Flexible bandwidth options
Increase or decrease connection bandwidth as workloads require, from small hybrid setups to enterprise-scale multi-site architectures.
Usage model
Choose the right model for your secure connectivity.
From hybrid cloud extension to disaster recovery and branch synchronization, HiTechCloud helps design private connectivity for each operational scenario.
Extend hybrid cloud for the enterprise
Securely connect on-premises sites to a HiTechCloud VPC to run sensitive workloads while keeping core data on site.
Multi-region disaster recovery
Set up secure tunnels between data regions to optimize real-time replication and run failover without exposing internal traffic.
Secure synchronization across branch offices
Connect branch offices over a private backbone, with shared VoIP, file servers, databases and management systems across locations.
Service plans
Optimize the site-to-site VPN plan for any workload size.
Choose the capacity that matches your multi-site connectivity requirements. Every plan includes strong IPsec encryption as standard.

FAQ
Frequently asked questions about site-to-site VPN.
Quick answers for businesses that need to connect on-premises systems, VPCs, and branch offices over a secure tunnel.
Does site-to-site VPN travel over the public internet?
Public Internet infrastructure can be used as the transport layer, but data travelling through the IPsec tunnel is encrypted and authenticated to protect traffic between endpoints.
Which encryption protocols are supported?
The solution centers on IPsec VPN with industry-standard encryption and authentication. HiTechCloud advises on the specific parameters based on your equipment and security policy.
Can I connect multiple VPCs to one on-premises site?
Yes. You can deploy a hub-and-spoke or multi-site topology to connect several VPCs, offices and data centers into one private network.
How do the Standard and Medium plans differ?
Standard suits a basic hybrid setup with up to 4 tunnels. Medium suits complex multi-site architectures and scales to 40 separate tunnels.
