I found this Kroger email VPN thing very interesting and thought you might too. I always thought VPNs were only for browsing the web privately. I had no idea that Kroger and other stores had their own for emails. It made me think about how important it is to keep our work emails safe, especially when they contain private or secret data. Anyone else heard of the Kroger email VPN or something like it? Why would a business set this up for emails?
