Among the enterprise-focused SD-WAN companies, a lot of solutions rely on deep packet inspection. It makes a lot of sense, it allows you to see specifically what application traffic is coming through the network, and allows you to do useful analysis. But deep packet inspection does have some performance and security considerations to take into account, and depending on compliance, might not be a viable option. That’s why I was interested to hear about Silver Peak’s SD-WAN solution. It’s an enterprise focused solution, but because of their WAN optimization heritage, doesn’t reply on DPI.
