Crucible Security runs in the cloud — no hardware, no per-seat math. So pricing doesn't need five confusing tiers. Run the free scanner today. Subscribe when the paid tier ships this summer.
Status: building now. Pre-subscribe now, billing starts at launch.
Three layers of defense against spam, scams, and robocalls. Tier 1 ships free for everyone — Tier 3 is the heavy artillery: a virtual gateway with an IVR challenge that kills ~95% of automated calls before your phone even rings.
Verify before ring. Your real number forwards to a virtual number. Unknown callers hit an IVR: "Press 5 to connect." Verified callers route through to your actual phone — robocalls don't press keys, so they never get through. Optional STIR/SHAKEN enforcement layer on top.
Available as an add-on for paid subscribers. Subscribe to the $15/mo tier first, then add Tier 3 from your dashboard, or pre-subscribe below.
Nessus charges $4,790/yr for vulnerability scanning alone. Intruder starts at $149/mo. Crucible Security ships AI agents, deception tech, and continuous monitoring starting at $15/mo. Here is how the numbers break down.
