Duo Security vs FusionAuth FAQ
- Which one is cheaper?
- Duo Security starts lower at $3/mo, compared to $162/mo for FusionAuth.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Different approach here. Duo Security uses per-seat pricing, while FusionAuth goes with usage-based. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. Duo Security: At $3-9/seat, Duo sits mid-pack in the identity/MFA space — cheaper than bundled enterprise IAM suites like Okta's access products, but pricier than bare-bones MFA-only tools. They're clearly going after Cisco's existing customer base and mid-market companies that want strong MFA without buying into a full IAM platform. FusionAuth: FusionAuth sits in the mid-market auth space competing with Auth0 and Okta CIC, and they're clearly positioning as the more developer-friendly, cost-transparent alternative. At $162/mo for 1K MAUs, they're not the cheapest (Clerk and Stytch have aggressive lower tiers) but they undercut Auth0 significantly at scale, targeting teams that got burned by Auth0's pricing as they grew.
