  The proliferation of vulnerable Internet-of-Things (IoT) devices has enabled
large-scale cyberattacks. Solutions like Hestia and HomeSnitch have failed to
comprehensively address IoT security needs. This research evaluates if
Wireguard, an emerging VPN protocol, can provide efficient security tailored
for resource-constrained IoT systems. We compared Wireguards performance
against standard protocols OpenVPN and IPsec in a simulated IoT environment.
Metrics measured included throughput, latency, and jitter during file
transfers. Initial results reveal Wireguard's potential as a lightweight yet
robust IoT security solution despite disadvantages for Wireguard in our
experimental environment. With further testing, Wireguards simplicity and low
overhead could enable widespread VPN adoption to harden IoT devices against
attacks. The protocols advantages in setup time, performance, and compatibility
make it promising for integration especially on weak IoT processors and
networks.
