Network infrastructure
Where we started.
Still where everything runs.
Before agentic engineering, Tethered was network infrastructure consulting: designing, building and keeping business networks reliable. Every system we build now inherits that discipline, and we still do the network work itself.
Services
Infrastructure your software can depend on.
Architecture & design
Network designs built around how your sites, teams and applications actually communicate, documented so they can be operated by anyone.
Segmentation & access
Separating users, devices, servers and guests so a problem in one place can't spread, with access granted by role, not by location.
Firewalls & secure remote access
Firewall policy design and cleanup, VPN and remote-access setups that are secure without being painful.
Site & cloud connectivity
Linking offices, data centres, cloud environments and AI model endpoints reliably, with private connectivity and redundancy where downtime is expensive.
Wireless
Coverage planning and enterprise Wi-Fi that holds up in real buildings, with separate secure networks per purpose.
Monitoring & documentation
Visibility into what's on the network and how it's performing, plus current diagrams and runbooks.
Assessments & remediation
Start by knowing what you have.
Many networks grow by accretion: a closet added here, a rule added there, a diagram last updated years ago. We map what's actually deployed, compare it with what you need, and deliver a prioritised plan, then carry it out if you want us to.
Every engagement delivers
- Current-state diagrams and an inventory
- Findings ranked by risk and effort
- A target design and migration plan
- Configuration and runbooks your team owns

Every network engagement is scoped to your environment.
