Frequently Asked Questions (FAQs) 1. What does WAN stand for?
WAN means Wide Area Network, connecting multiple locations or offices over large geographical distances.
2. How does WAN Optimisation work?
It speeds up data transmission using compression, caching, deduplication, and latency reduction techniques.
3. How much does WAN Optimisation cost?
Typical costs range from £200–£800 per site per month, depending on bandwidth and features.
4. Is WAN Optimisation the same as SD-WAN?
Not exactly. SD-WAN manages and routes network traffic, while WAN Optimisation improves data transfer efficiency. They’re best used together.
5. Does WAN Optimisation improve cloud performance?
Yes – it optimises data paths to cloud platforms like Azure, AWS, and Google Cloud, reducing latency and improving reliability.
6. Is WAN Optimisation secure?
Yes. It includes encryption, firewalls, and secure tunnelling for data integrity across all connections.
