SD-WAN, IPsec and affordable internet: network reliability without the premium price

Dedicated lines used to be the only route to a reliable network. How SD-WAN, IPsec and affordable internet links deliver the same reliability for less.

Businesses depend on network connectivity that simply works. For years, expensive dedicated connections were the standard for reliability. Today a well-designed combination of software-defined networking, encryption and affordable internet links can match them at a fraction of the cost. This is how the three parts work together.

Software-defined wide area network (SD-WAN): the navigator

SD-WAN steers your traffic across all available connections. It chooses the best path for each application at every moment and switches when a link degrades, turning several ordinary internet links into one network you can rely on. Our specialists design and tune it, so your critical applications get the best route.

Internet Protocol Security (IPsec): the secure container

IPsec encrypts the traffic between your sites and the cloud, so it travels safely across the public internet. It gives you strong protection without the price of private lines: a smart lock on your cargo rather than a fleet of armed guards.

Fibre, cable and digital subscriber line (DSL) connections from different providers cost a fraction of a dedicated line. Combined, they give you redundancy: when one fails, traffic continues over the others.

The principle behind it

Large cloud providers do not build their storage on a few expensive disks. They spread data across many ordinary drives and let software handle the failures. Your network can follow the same principle: not one costly pipe, but several affordable links, orchestrated by software and secured by encryption.

Reliability is a design choice

Network reliability is not about the price of individual components. It is about combining them well. With SD-WAN as the navigator, IPsec as the shield and affordable links as the backbone, your network rides out failures and keeps costs in check. We design, implement and manage it for you, as part of a network that also connects your sites securely to Azure.
