Enterprise networks
Architecture and technical leadership for routed, switched, wireless and hybrid environments. We help teams simplify complexity without compromising resilience.
Cisco routing and switchingIndependent network and security consultancy
Critical systems. Clear decisions.
We design, harden and assure the IT and operational technology environments organisations rely on every day.
Technical depth that holds up in the real world.
Silicon Circle brings together enterprise networking, cyber security and OT security expertise. We give boards, delivery teams and operational leaders a practical route from current risk to a secure, supportable target state.
One practice across connectivity, security and operations.
Our work starts with the dependencies that matter: people, production, applications, suppliers and the infrastructure connecting them.
Cyber security
Security architecture, segmentation, exposure reduction and actionable improvement plans.
Palo Alto Networks consultingOT security
Practical protection for systems that run physical processes, shaped around NIS, CAF and IEC 62443 where relevant.
OT security consultingHardening
Secure baselines for networks and assets, built around operational constraints and sustainable ownership.
Network and asset hardening
Network decisions with operational consequences.
From campus and data centre switching to complex WAN, secure remote access and network segmentation, we bring independent technical judgement to the decisions that will shape your environment for years.
Our Cisco routing and switching capability covers architecture reviews, standards, migration planning, resilient design, configuration assurance and hands-on delivery support.

Hardening is more than a configuration review. It is a disciplined way to reduce exposure across the network, the asset estate and the people responsible for keeping both secure.
Secure network baselines
Reduce attack surface across routing, switching, wireless, firewalls and remote access.
Asset hardening
Prioritise secure configuration, patching, firmware, services and privileged access.
Segmentation
Build practical boundaries between users, applications, infrastructure and OT systems.
Operational ownership
Turn controls into repeatable standards, change practices and evidence your teams can use.
Security only works when it understands the operation it is protecting.
That is why we work across enterprise IT and OT, combining a clear view of cyber risk with the engineering realities of availability, safety and change control.
Start with the problem you need to solve.
A short outline is enough. We will respond with useful questions and a clear next step.
