13 Feb Learn what SD-WAN is and how it protects your business network

In a corporate environment where remote working and the cloud are the norm, traditional security perimeters have become obsolete. For many organisations, the key question today is: SD-WAN, what exactly is it and how can it help shield my infrastructure?

This technology (Software-Defined Wide Area Network) acts as a virtual intelligence layer that manages traffic via software instead of relying solely on rigid hardware. Its function is to decide in real time the most optimal and secure route for every piece of data, allowing network security to be proactive, automated, and resilient.

Intelligent networks: speed without sacrificing protection

Traditionally, advanced security often slowed down data traffic. With SD-WAN technology, this paradigm changes, allowing the flow of information to be protected automatically without penalising user speed.

Total visibility and threat detection

One of the greatest advantages of implementing SD-WAN is its monitoring capability. It allows for real-time visibility into what is happening at every network node, facilitating the detection of strange user behaviour or suspicious devices.

Micro-segmentation: the shield against propagation

Modern network security is based on the “zero trust” principle. SD-WAN allows critical areas (such as payment data) to be isolated from the rest of the network so that, if an attack occurs at one point, the threat remains contained and does not spread.

Centralised management and incident response

The complexity of managing multiple sites is often a weakness. SD-WAN solves this problem through a centralised control panel:

• Automatic updates: Security patches are applied simultaneously across all sites, ensuring there are no weak points.
• Encrypted traffic inspection: This technology inspects traffic even when it travels encrypted, ensuring that camouflaged viruses do not enter through secure connections.
• Resilience against outages: If a fibre line suffers an attack or a cut, the system automatically redirects traffic through another route without the user noticing.

lyntia’s commitment to digital trust

At lyntia, we understand that connectivity and cybersecurity are inseparable assets for the success of any business. This strategic vision drives us to integrate advanced solutions like SD-WAN within a much broader and certified protection framework.

In fact, the press article titled “lyntia reinforces its commitment to security and digital trust” details how the company has achieved a score of 770 on the BitSight index, placing it at the forefront of the telecommunications sector’s best practices.

Conclusion: the value of an intelligent network

Choosing SD-WAN involves recognising that the network needs to be intelligent to adapt to the threats of the future. By integrating traffic management with advanced network security, companies not only gain efficiency but also protect their most valuable asset: information.
