Hey everyone, I'm a front-end developer/designer, and I've been working on a SaaS tool that has attracted interest from a potential enterprise client. They raised some important questions about security and privacy compliance, and since I'm not an expert in this area, I'm looking for some assistance. I'm searching for reliable freelancers or small agencies that specialize in security audits for SaaS products.
My tech stack is primarily React and TypeScript for the front end, and I use Supabase for the database, with edge functions handling various integrations like Resend and OpenAI. While I believe I have solid row-level security policies, I'm not completely sure how protected I am against threats like JavaScript or SQL injection that could compromise customer data. Appreciate any recommendations or advice!

Did you personally code the tool, or is it more vibe-coded? Any enterprise client usually expects assurance about not just the current codebase, but also that best practices are followed continuously.
If your potential client mentioned compliance, they likely want to see formal certifications like PCI or ISO 27001, which could be costly. You might be able to use available tools to gauge compliance yourself and present that data, but just make sure they’d be fine with that instead of official certification.
For a smaller SaaS tool, you probably don’t need a full-on penetration testing firm just yet. If you've set up Supabase RLS correctly, that's a great start, but watch out for missing policies on junction tables or storage. You’re likely safe from SQL injection due to the Supabase client library using parameterized queries. The bigger concern with React is XSS, so make sure you’re not using dangerouslySetInnerHTML and sanitize user-generated content. If you're looking for a company for an audit, check out Cure53 or Doyensec – they're reputable without the enterprise price tag. For a more affordable assessment, consider hiring someone from Bugcrowd or HackerOne. Also, you might want to look into getting a SOC 2 Type 1 report via Vanta or Drata; many enterprise clients expect this as proof of security.
This is such a helpful answer, thanks a lot! I’ll definitely check out those options. Vanta looks great for what I need, but they also mentioned OneTrust for security validation – any thoughts on that?
Good point! It seems OP might need someone to assist in calls with the enterprise client to provide assurance. SOC 2 is definitely a good direction once they have stable revenue.
A mix, really. I did about 10% myself but leaned on vibe coding. I’ll need to figure out observability since I don’t have much in place beyond Supabase’s basic reporting. They’re okay with being my first enterprise client but want assurance, especially regarding passing tests with OneTrust.
