An honest, context-aware comparison. No affiliate links. No paid placements. Just the data that helps you decide.
Nuclei (ProjectDiscovery)

Duo Security (Cisco)
Multi-factor authentication and secure access platform
Side-by-Side Comparison
Objective metrics, no spin.
Security teams running continuous surface scans, bug bounty hunters, and red teams needing fast signature-driven testing.
Teams looking for deep SAST or SCA — Nuclei is about active probing of exposed assets, not codebase analysis.
For adding MFA to protect apps and VPN. Very user-friendly, great for organizations starting with MFA.
If you need full IAM platform (use Okta) or already have MFA through Microsoft/Google.
