Verifpal is Beta Software

Verifpal now benefits from a higher level of assurance due to the formalization of its syntax, semantics and analysis methodology, both by hand and using the Coq theorem prover. However, it remains classified as beta software due to its relatively young age, especially when compared to similar tools, such as ProVerif, that have been in development for more than twenty years.
