Connectivity & Network Services — Built for Speed, Reliability, and Value
Your business depends on reliable, high-performance connectivity. At Commstec IT Services, we design, deliver, and manage secure network solutions across Sheffield and South Yorkshire — from leased lines and FTTP to SD-WAN and enterprise-grade firewalls.
Our approach combines wholesale circuit pricing, local engineering expertise, and full network visibility to keep your business connected, protected, and in control.
Business Connectivity Sheffield — Reliable by Design
When uptime matters, so does the quality of your connection. Commstec provides business-grade leased lines, FTTP, and SoGEA circuits built for performance and resilience.
We work directly with national carriers to supply circuits at wholesale cost, passing the savings straight to you. Whether you’re connecting a single site or multiple branches, every solution includes proactive monitoring, SLAs, and 24/7 support as standard.
Our connectivity options include:
- Dedicated Leased Lines — symmetrical speeds up to 10Gbps
- FTTP and SoGEA — cost-effective access for smaller sites
- 4G/5G backup connectivity — automatic failover for uninterrupted service
Small Business Networking — Simplified and Secure
A strong connection is only half the story. We build complete network environments that make your infrastructure faster, more secure, and easier to manage.
From routing and switching to Wi-Fi and access control, our engineers design single-vendor, scalable networks with built-in visibility and performance optimisation.
Capabilities include:
- Network design, deployment, and lifecycle management
- Unified LAN, WAN, and Wi-Fi architecture
- Centralised performance and health monitoring
Secure Access & Firewall Management
Connectivity without protection isn’t an option. Every Commstec network includes built-in security controls that protect users, devices, and data wherever they connect from.
Our managed firewalls and SD-WAN platforms combine real-time threat intelligence with intelligent routing, ensuring performance never comes at the expense of security.
Features include:
- Managed firewalls with active threat prevention
- Secure VPN access for hybrid and remote workers
- SD-WAN with automated path selection and QoS for cloud workloads

Smarter Connectivity with SD-WAN
SD-WAN brings cloud-ready networking to Sheffield businesses. By intelligently routing traffic across multiple connections — such as leased lines, FTTP, and 4G/5G — it ensures critical applications like Microsoft 365, Azure, AWS, and other SaaS platforms always use the fastest, most reliable path available.
Unlike a single leased line, which ties performance and cost to one connection, SD-WAN aggregates multiple lower-cost links to deliver comparable or better performance for less money. Bandwidth can be added or rebalanced without expensive circuit upgrades, and you’re no longer locked into a single carrier or contract.
Key benefits:
- Lower costs: Combine broadband, FTTP, and mobile data links to replace or supplement expensive leased lines.
- Higher availability: Automatic failover keeps users connected even if one link drops.
- Improved cloud performance: Dynamic path selection prioritises latency-sensitive traffic such as VoIP, Teams, or CRM systems.
- Centralised management: One interface for visibility, analytics, and policy enforcement across every site.
- Stronger security: Built-in encryption and next-generation firewalling protect data in transit.
- Scalability: Add new locations or users without major reconfiguration or downtime.
Smarter Connectivity with SD-WAN Sheffield
For most organisations, SD-WAN delivers the resilience of enterprise networking with 20–40% lower running costs than traditional leased-line-only designs. It’s the ideal solution for multi-site businesses, hybrid workers, and anyone needing predictable performance for cloud-based workloads.
