Rapid response support, delivered remotely and on-site across the UK. Comprehensive infrastructure and network services with clear ownership, documented change control, and pragmatic engineering.
Infrastructure is the foundation every other service relies on. When it is designed well and managed properly, your teams stay productive, systems stay available, and security controls work as intended. When it is neglected or “just about working”, it becomes a business risk: outages, performance bottlenecks, failed changes, and security gaps that can be exploited at speed.
GEN provides managed infrastructure and network services that keep your estate secure, resilient, and ready for growth. From the perimeter through to switching and routing, remote access, SDN/SD-WAN, and proactive monitoring, we take ownership of the day-to-day operation with clear documentation, controlled change, and practical engineering.
The difference is not just “keeping it running”. It is reducing risk: least-privilege access, predictable configurations, rapid detection of issues, and a plan for failure. We help you avoid the situations where a single mistake, a single device, or a single link can take down a site or expose data.
Your perimeter is the front door to your organisation. It is where internet gateways, firewalls, routers, NAT, and policy controls decide what can reach your systems and what your systems can reach. It is also where the majority of opportunistic scanning, exploitation attempts, and credential-based attacks land.
This is a high-risk area because the blast radius of an error is so large. One misconfigured rule can mean a near-instant data breach, ransomware entry, or unauthorised access to sensitive services, with all the operational, legal, and reputational impact that comes with it. Attackers do not need weeks; they often need seconds.
We manage the perimeter with disciplined change control and security engineering practices: standardised configurations, strong authentication for management access, firmware lifecycle management, regular policy review, and logging that supports investigation. Where appropriate, we implement segmentation, geo/IP reputation controls, intrusion prevention, rate limiting, and safe publication patterns (reverse proxies/WAF) so services are not exposed unnecessarily.
Internal infrastructure is where reliability and performance are won or lost. Cabling quality, switching, VLAN design, routing, and addressing determine whether services are fast and stable, or intermittently slow and fragile. Small configuration problems can cascade into major incidents: loops and broadcast storms, VLAN leakage, asymmetric routing, MTU mismatches, or IP conflicts that are difficult to diagnose under pressure.
We manage the fabric of your network end-to-end: structured cabling and cabinet layout through to LANs, VLANs, switching, routing, and Wi-Fi integration where required. This includes IP plans, DHCP/DNS integration, segmentation for security and performance, and consistent configuration management so changes are controlled, peer reviewed where appropriate, and traceable.
We also have the capability to install and maintain structured networks across copper and fibre. This includes CAT5e through to CAT8 copper, and multimode fibre (OM3/OM4/OM5), as well as long-distance singlemode fibre (OS2) for campus and carrier-grade runs. Every point we install is fully tested and certified, with documented results provided as evidence of performance and compliance.
You also get documentation and diagrams that match reality. That reduces risk, shortens outage time, and makes auditing and future change safer because decisions are made on accurate information rather than guesswork.
Remote access is essential, but it is also a common entry point for attackers. The goal is simple: make access convenient for legitimate users, and extremely difficult to abuse.
We provide managed VPN services with Single Sign-On (SSO), strong authentication (including MFA), and least-privilege routing so remote users and third parties can reach only the services they are explicitly permitted to use. Routes are tightly scoped into select services, reducing the risk of lateral movement if a device or account is compromised.
We can also implement device posture checks and access controls where appropriate, along with auditing so you can evidence who connected, when, and what they could access. This creates a remote access service you can trust, rather than a permanent “back door” into the network.
Software Defined Networking (SDN) and SD-WAN capabilities help you standardise and automate networks across sites. Done well, they reduce operational load, improve consistency, and make change safer. Done poorly, they can amplify mistakes across every location.
We design and manage centrally controlled policies, dynamic routing, segmentation, and application-aware connectivity so you can improve performance and simplify operations. This includes templated configuration, controlled rollouts, and governance that prevents “quick fixes” becoming permanent technical debt.
Where it makes sense, we introduce automation for provisioning, configuration drift detection, and backup/restore. The outcome is a network that is easier to operate and more predictable under change.
Monitoring turns “we think it is fine” into “we know it is fine”. Proactive monitoring reduces downtime by detecting issues early, before they become outages, and by providing the evidence needed to fix problems quickly.
We provide remote monitoring of network and infrastructure health, alerting, trend analysis, and automated responses to common issues where safe to do so. This includes checks for link stability, capacity, interface errors, device health, service availability, certificate expiry, and unexpected configuration changes, with clear escalation paths into our support process.
We also focus on resilience-by-observation: spotting degradation patterns, forecasting capacity, and highlighting risks like failing hardware, noisy links, or recurring errors that indicate deeper problems.
Resilience is about planning for failure and ensuring your business stays online. Hardware fails, links go down, power events happen, and human mistakes occur. The question is not whether something will fail, but what happens when it does.
We help you identify single points of failure and design mitigations such as redundant links, diverse routing, high availability firewall pairs, and sensible failover strategies. We can also help define practical recovery objectives and priorities so investment is aligned to what matters.
Finally, resilience must be operational. We document recovery procedures and test them where possible, so when something goes wrong, service is restored quickly and predictably, with minimal guesswork.
