Cilium vs Virgil Security: What are the differences?

Developers describe Cilium as "API-aware networking and security for containers". Open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes. On the other hand, Virgil Security is detailed as "We make every developer into an applied cryptologist". Virgil consists of an open-source encryption library, which implements CMS and ECIES(including RSA schema), a Key Management API, and a cloud-based Key Management Service.

Cilium and Virgil Security belong to "Security" category of the tech stack.

Some of the features offered by Cilium are:

• Identity Based Security - Cilium visibility and security policies are based on the container orchestrator identity (e.g., Kubernetes labels). Never again worry about network subnets or container IP addresses when writing security policies, auditing, or troubleshooting.
• Blazing Performance - BPF is the underlying Linux superpower to do the heavy lifting on the datapath by providing sandboxed programmability of the Linux kernel with incredible performance.
• API-Protocol Visibility + Security - Traditional firewalls only see and filter packets based on network headers like IP address and ports. Cilium can do this as well, but also understands and filters the individual HTTP, gRPC, and Kafka requests that stitch microservices together.

On the other hand, Virgil Security provides the following key features:

• End-to-end encryption
• Passwordless authentication
• Data verification
