What security do I need for a SaaS MVP?

At minimum: proper authentication, data isolation between customers, HTTPS, secure payment processing, and the ability to respond to security issues. You can add more as you grow, but these are non-negotiable.

Do I need SOC 2 compliance for launch?

Not for initial launch. SOC 2 becomes important when selling to enterprises. Focus on fundamental security first. You can pursue compliance certifications as customer requirements demand.
