TLSguard — Security Audits for SaaS: Affordable security audits for early-stage SaaS founders

Enterprise pentest firms typically start at $3,000-5,000 and take weeks - often excessive for a small SaaS team without funding. TLSGuard delivers the same OWASP and API testing, scoped for early-stage founders. Each audit includes a plain-English report with proof-of-concept for every vulnerability, plus clear fix steps — understandable by technical and non-technical co-founders alike. Quick scan from $50. Full audit $250, delivered in days, not weeks.

In the startup industry, the standard approach focuses on rapid product release and early monetization. For testing hypotheses, this method is effective, and I have experienced this firsthand while developing my own products. However, security considerations in such environments are frequently overlooked. The complexity lies in the fact that superficial development flaws do not manifest when the user base is limited to a few dozen participants. They emerge during critical moments - such as unauthorized access to API credentials or attempts to destabilize the service. Automated code generation systems, such as Cursor or Replit Agent, accelerate development but do not account for security requirements. They omit rate limiting configurations, leave excessive information in system logs, and skip essential security headers. We encountered this in practice during an audit of PetHill, a pet care SaaS application. When submitting automated requests to the registration page, the system became unresponsive under load, returning HTTP 500 errors. Entering invalid data at the same endpoint resulted in identical server failures, which were accompanied by the disclosure of internal stack traces. Such situations do not involve critical vulnerabilities like remote code execution or SQL injections. Nevertheless, precisely these architectural shortcomings undermine trust during negotiations with corporate clients. A full-scale penetration test at the initial stage is not always required. However, addressing basic vulnerabilities is an essential step prior to engaging with major enterprise customers. If your application was developed using artificial intelligence tools, you are welcome to share information about your project in the comments to discuss its security aspects.

honestly love that the reports come with proof-of-concept for each vulnerability — that kind of transparency is exactly what makes the $250 price feel reasonable instead of sketchy, you know

The $50 quick scan tier is a smart way to lower the barrier for early-stage founders who just need a sanity check before investor demos.
