Arsen Vishing Simulation vs King Phisher: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Arsen Vishing Simulation is a commercial phishing simulation tool by Arsen. King Phisher is a free phishing simulation tool. Compare features, ratings, integrations, and community reviews side by side to find the best phishing simulation 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:
Mid-market and enterprise security teams need vishing simulation because voice phishing bypasses email filters and exploits the human trust gap that text-based attacks can't replicate; Arsen Vishing Simulation trains this specific weakness through AI-generated calls and coordinated follow-up blends that force employees to recognize social engineering across channels. The platform's real-time adaptive scenarios and multi-step orchestration directly strengthen NIST CSF 2.0 PR.AT awareness outcomes by simulating how attackers actually operate, not how they theoretically should. Skip this if your organization hasn't closed basic email phishing awareness first, or if you need a single vendor covering both email and voice simulation; Arsen is voice-only by design.
Security teams with limited budgets who need hands-on control over phishing simulation will find King Phisher's open-source design and zero licensing cost hard to beat; you build campaigns directly rather than waiting for vendor-managed templates. The 2,442 GitHub stars reflect active community contributions and real-world deployments across mid-market organizations. Skip this if your team lacks Linux administration chops or needs polished UI workflows and managed reporting; King Phisher demands more operator effort than commercial alternatives like Gophish or Evilginx2, and you'll spend time on infrastructure instead of just running tests.
