Securing Inter-Office Traffic
Private links reduce exposure, and encryption adds another layer. Here is how to protect data moving between sites.
Data moving between your offices includes customer records, financial transactions, HR information and intellectual property. Protecting it in transit is a core part of network security.
Private by design
Business Connect keeps inter-office traffic off the public internet. This significantly reduces exposure to interception and attacks compared with internet-based connections.
Adding encryption
For sensitive environments — financial services, healthcare, legal — encryption adds an extra layer. IPsec tunnels on managed routers encrypt traffic between sites, so data remains protected even on private links.
Segmentation across sites
Use VLANs and routing policies to keep different types of traffic separate: finance systems, general office traffic, CCTV and guest networks should not mix, even across sites.
Centralised firewalling
In hub-and-spoke designs, a firewall at the hub inspects traffic between branches and the internet. Cloud firewalls offer the same capability for local-breakout designs.
Access control
Limit which sites and users can reach which systems. A branch's guest network should never reach head office servers.
Monitoring
Monitor traffic patterns between sites. Unexpected flows can indicate malware or misconfiguration.
Physical security
Protect network equipment at each site in locked cabinets or rooms. A physically accessible router is a security risk.
Regular reviews
Review routing and firewall policies periodically as sites and applications change.
The bottom line
Layered security — private links, encryption where needed, segmentation, firewalling and monitoring — keeps your data protected as it moves between offices.
