Technology and SaaS companies face the dual challenge of securing their own infrastructure while building security into the products they deliver to customers. As custodians of customer data across multi-tenant environments, SaaS providers must demonstrate compliance with SOC 2, ISO 27001, and increasingly GDPR and CCPA. Supply chain security is critical — a vulnerability in a widely-used SaaS platform can cascade to thousands of downstream customers. DevSecOps, secure SDLC, and continuous vulnerability management are essential practices.
