Frequently Asked Questions

What security does a SaaS app need?

At minimum: authentication with MFA, role-based access control, encryption at rest and in transit, rate limiting, input validation, CSP headers, audit logging, and a incident response plan. Missing any of these creates a vulnerability.

How do I know if my SaaS is secure?

Run through this checklist. If you can't check every item, you have gaps. A professional security audit (like Ground Zero LLC's $2,500 flat audit) will identify what you're missing.
