Connect your branches with a more flexible architecture with the ability to use multiple hardware platforms and connections.

Unlike a traditional WAN where the control software is integrated with the hardware and connects multiple LANs through routers and VPNs, SD-WAN works with any network hardware that is separate from the underlying HW.

In addition, it combines WAN technologies, i.e. multi-protocol label switching and broadband connections. This gives organizations more options for what HW to use and more. The “Overlay” networking solution provides the user with significant flexibility and therefore savings in the solution.

The SD-WAN router allows you to perform many more functions on the network than traditional IP forwarding. With security features such as ZoneBased Application Aware Firewall, Intrusion Detection/Protection System (IDS/IPS), Advanced Malware Protection (AMP – Antivirus), URL Filtering, TLS/SSL decryption, etc. Reduce the number of devices at branch offices and reduce the cost of your company’s IT structure.

Do you know the benefits of using SD-WAN?

1. HIGH SECURITY

  • security through end-to-end encryption
  • advanced cybersecurity protection

2. FLEXIBILITY AND SCALABILITY

  • fast migration of cloud solution
  • efficient network expansion/reduction

3. EASY MONITORING

  • centralised management of the entire network in one place
  • possibility to prioritize applications that are critical for the company’s operation
  • predictable SLA and detailed reporting

4. MAXIMUM PERFORMANCE

  • support for all standard protocols
  • routing traffic through the most appropriate available data paths

5. COST SAVINGS

  • you can choose cheaper HW – you are not tied to one supplier
  • you use a regular internet connection (MPLS bandwidth is expensive)

For work-from-home SD-WAN you will appreciate

Already at the time of the coronavirus pandemic, there was an increase in traffic with employees connecting remotely to the corporate network via VPN.

Many companies have had to increase capacity to accommodate the growing number of VPNs. In many cases, the company’s VPN was sufficient after modification, but for some organisations it could not provide a reliable and secure environment with a high level of control and monitoring.

This led to the deployment of SD-WAN in the home offices of its employees. They were able to conduct video conferencing, VoIP calls and streaming training without interruptions and under the supervision of internal network administrators. It’s clear that SD-WAN is an increasingly popular choice for businesses with the growing trend of telecommuting.
