Vanguards Onion Service Addon vs Stamus Networks Clear NDR: 2026 Comparison

Tor administrators running hidden services who need hardened defenses before Tor core integrates these protections should deploy Vanguards Onion Service Addon; it plugs specific attack vectors like guard discovery and introduces rate-limiting that the base controller lacks. The addon is free and actively maintained on GitHub with 240 stars, indicating real adoption among threat-sensitive operators. Skip this if your organization doesn't rely on onion services or runs them as secondary infrastructure; the value proposition is narrow and the operational overhead of managing a separate controller addon isn't justified for casual users.
