VAPT for SaaS companies

Enterprise buyers, SOC 2 and ISO 27001 auditors, and security questionnaires all expect SaaS vendors to evidence independent penetration testing. CyberSigma performs application, API and cloud VAPT for SaaS products — multi-tenant isolation, authentication and authorisation, API abuse, and cloud configuration — and delivers a report you can share with customers plus a free retest to evidence closure. Testing is grey-box and business-logic-aware, not just automated scanning.
