When more of the workforce shifts to working remotely, it puts new and different strains on the infrastructure across different parts of the network, especially where VPN gateways connect to the network edge. This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN).

Border Gateway Protocol (more commonly known as BGP ) is the routing protocol that makes the internet work. Time and time again, this resulted in a “BGP prefix hijack,” where, in many cases, part of the internet was unreachable. The entire RPKI process stands outside of the BGP routing protocol itself.
