VAPT for SaaS Companies — close enterprise deals faster

Enterprise customers send security questionnaires and ask for a recent penetration test before they sign. We test your product the way an attacker would — multi-tenant access, roles, APIs and cloud — give you a report you can share with customers, and help your engineers fix every finding.

    Overview

    The pentest your enterprise customers ask for.

    For a SaaS product, the biggest risks are one customer seeing another customer’s data, broken roles and leaky APIs. We test these by hand, review your cloud setup, and give you two documents: a detailed report for your engineers and a short summary you can share with customers. That helps with security questionnaires, SOC 2 and ISO 27001.

    FAQ

    Questions before you start

    Can we share the report with customers?−

    Yes. You get a detailed report for your team and a short summary letter you can share with customers and prospects under NDA.

    Does this help with SOC 2 and ISO 27001?+

    Yes. Findings are mapped to SOC 2 and ISO 27001 controls, and the retest evidence helps during audits. SOC 2 penetration testing →

    Will testing affect production?+

    We prefer a staging environment that mirrors production. If production must be tested, we agree windows and avoid destructive actions.

    What do you need from us to start?+

    Product URLs, test accounts for each role in two separate tenants, API docs, and read-only cloud access if cloud is in scope. We sign an NDA first.

    Do you help us fix what you find?+

    Yes. Every finding comes with clear, step-by-step fixes, and our team stays with your developers until the critical issues are closed and retested.
