CST VerdictBased on our analysis of core features, company size fit, deployment model, here is our conclusion:
Startup security teams with limited budgets and straightforward Linux infrastructure should use DomainBlocker Tool to enforce domain blocking without adding licensing costs or agent overhead. It deploys directly via iptables/ip6tables rules on existing Linux systems, giving you immediate Protect function coverage with zero per-seat fees. Skip this if you need centralized management across heterogeneous endpoints or macOS/Windows systems; DomainBlocker is CLI-driven and Linux-only, requiring manual rule updates across servers rather than policy distribution from a control plane.
