Overview
Connectivity you can count on
When your internet drops, so does your business, cloud apps, email, phones and card payments all rely on it. A single connection with no backup is a single point of failure.
WhizzIT sources and manages the right connectivity for each site, adds automatic failover, and uses SD-WAN to intelligently route traffic across links, so you get resilient, prioritised, always-on connectivity you don’t have to think about.
Connectivity is designed around how your sites actually communicate, then managed as one service rather than several separate supplier relationships. It is priced per user at a fixed monthly cost rather than bundled into rigid packages, so it scales with your team. Everything runs through the same UK service desk that handles your day-to-day tickets, so there is no separate team to chase. Across 2025 our average first response time was 9 minutes and our average resolution time was 6 hours, measured across every ticket we handled.

How resilience actually works
Two lines are not resilience if they share a duct
Buying a second connection feels like buying resilience, and often is not. If both circuits run from the same exchange, along the same route, or terminate on the same piece of your equipment, one contractor with a digger takes out both. Diversity has to be designed rather than assumed.
-
Diverse carrier, diverse route, diverse hardware
Genuine resilience means the two services do not share a failure point: different providers where possible, physically different routes into the building, and separate terminating equipment. Where a truly diverse fixed route is not available at a site, 4G or 5G backup gives you a path that fails independently by definition, because it does not use the ground at all.
-
Failover that happens before anyone notices
The value is in how fast and how quietly the switch happens. A failover that drops every call and every session is better than an outage, but only just. SD-WAN monitors the health of each path continuously and moves traffic when a link degrades, not only when it dies completely, which matters because slow and lossy is more common than fully down.
-
Not all traffic deserves the same treatment
A voice call is ruined by 100ms of jitter that a file upload would never notice. Policy-based routing lets you put real-time traffic on the most stable path and bulk transfers on the cheaper one, and change that automatically when conditions shift. This is the part that a straight second line cannot do at all.
-
Bandwidth is rarely the actual problem
Most sites that feel slow are not short of bandwidth. They are suffering from contention at peak times, a saturated upload path, or one backup job running in business hours. Measuring before upgrading usually costs less than upgrading, and sometimes shows the circuit was never the constraint.
Contracts and practicalities
Lead times decide project dates more often than budgets
New fixed circuits are quoted in weeks and occasionally months, particularly where a new fibre build or a wayleave from a landlord is involved. Anyone planning a move, a fit-out or a new site should start connectivity first and everything else around it, because it is the one element that cannot be compressed by working harder.
We source and manage the circuits rather than leaving you to hold the carrier relationship, so a fault is our call to make and chase. Connectivity sits alongside managed firewall at the network edge, and the monitoring that proves a link is degrading is covered by network monitoring.

Frequently asked questions

020 4634 2518What is SD-WAN?
SD-WAN (software-defined WAN) intelligently manages and routes traffic across multiple internet connections and sites, improving resilience and performance and prioritising business-critical applications.
What happens if our main internet line fails?
With automatic failover, for example to a second line or 4G/5G, your connectivity switches over automatically, keeping you online while the primary line is restored.
Can you connect multiple offices?
Yes. We design and manage secure, reliable connectivity between your sites so they work as one network, with central management and monitoring.
Do you provide the internet lines too?
Yes. We source leased lines and business broadband on your behalf, then configure and manage the whole connectivity setup as a single service.
Technology partners
Brands we partner with
We hold partner status with the vendors behind the tools we deploy, so your licensing, support and escalation come direct from the source rather than through a reseller chain.
