  • Each has a real cost: 1Password no free tier; all plans require paid subscription; Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments

1Password

  • No free tier; all plans require paid subscription

  • Enterprise plan does not include free trial access

Cilium

  • Requires a recent Linux kernel, which rules out older distributions and some managed environments
  • eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
  • Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

Individual plan costs 2.99 USD per month or 35.88 USD annually. Families plan costs 59.88 USD per year and includes five licenses with the ability to add more for 1 USD per month each.
