DomainBlocker Tool is a free network access control tool. HPE Aruba Networking is a commercial network access control tool by HPE Aruba Networking. Compare features, ratings, integrations, and community reviews side by side to find the best network access control fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, 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.
Mid-market and enterprise networking teams managing mixed wired, wireless, and IoT environments will get the most from HPE Aruba Networking Central because it consolidates network access control with SD-WAN and SSE into one console, eliminating the tool sprawl that usually forces separate vendor relationships for each layer. The platform covers all three NIST CSF 2.0 infrastructure resilience functions,identity management, continuous monitoring, and security architecture,which means you're not inheriting detection gaps downstream. Skip this if your organization runs a purely cloud-native network or lacks the operational depth to operationalize zero trust; the deployment complexity and integration touchpoints demand mature NetOps teams, not quick wins.
