Aikido DAST Scanner vs FYEO Custom Fuzz Testing: Side-by-Side Comparison (2026)

Short answer

Mid-market and SMB teams that need continuous API security visibility without hiring dedicated AppSec staff should start here with Aikido DAST Scanner. It handles REST, GraphQL, and authenticated flows in a single scan cycle, and the automated Swagger generation means you're mapping attack surface the day you deploy, not weeks later. Skip this if you need SAST or SCA baked in; Aikido is DAST-only, which keeps it fast but leaves code and dependency risk uncovered. Mid-market and enterprise teams securing Layer-1 protocols, smart contracts, or custom DeFi runtimes need FYEO Custom Fuzz Testing because it builds harnesses around your actual threat model instead of running generic fuzzing templates against your code. The stateful execution with shadow-state tracking and invariant checking catches logic flaws that stateless fuzzers miss, and CI integration means you're re-running those same reproducible seeds on every release. Skip this if your codebase is small or you're looking for a self-service tool; FYEO's 12-person team is built for hands-on engagement with mid-market and up, and that model doesn't scale to solo developers or teams that need instant turnaround.
