Several regulatory standards impose data protection and compliance requirements on organizations and specify the use of encryption, including PCI, SOX, HIPAA, and GDPR. Encrypting traffic using a standard approach like TLS, for example, requires SSL certificates and results in more complexity and operational overhead for IT organizations that are already overburdened.
Calico avoids unnecessary complexity by utilizing WireGuard to implement data-in-transit encryption. WireGuard runs as a module inside the Linux kernel and provides better performance and lower CPU utilization than IPsec and OpenVPN tunneling protocols. Independent benchmark tests of Kubernetes CNI’s have shown that Calico with encryption enabled is 6x faster than any other solution in the market. And with Calico, you’ll maintain visibility into all traffic in your Kubernetes clusters even when encryption is deployed.
