- What is the best Thales Sentinel alternative?
- ValidonX is a strong Thales Sentinel alternative for API-first and SaaS products: it is multi-tenant by design, starts free (then $49/month), and issues offline-verifiable Ed25519-signed JWT licenses over REST — no hardware dongles or sales-led rollout.
