Before you sign an SD-WAN or WAN contract
- What is the contract term, and what does early termination actually cost?
- Is the underlay included, or are you buying circuits separately?
- Who owns the configuration — you, the provider, or a third party?
- What happens to your policy configuration if you leave?
- Are the service levels measured end-to-end or only on the provider's segment?
- What is the documented process when two vendors blame each other?
