Why SAML SSO is non-negotiable for modern B2B SaaS apps

In the SaaS industry, integration with enterprise identity standards is crucial for attracting and retaining customers, with SAML being a key requirement despite perceptions of it as a legacy protocol. Many enterprises, including Global 2000 companies, rely heavily on SAML for security and compliance, making its support essential for vendors wishing to penetrate these markets. Ignoring SAML can result in lost opportunities, as enterprise buyers prioritize vendors that integrate smoothly with their existing single sign-on (SSO) ecosystems. While modern standards like OpenID Connect (OIDC) are important, a hybrid identity strategy that includes SAML, OIDC, and SCIM is necessary to address the diverse needs of both cloud-native startups and regulated enterprises. This approach ensures scalability, security, and alignment with customer expectations, ultimately serving as a revenue strategy by enabling access across various business environments. Supporting SAML and a comprehensive identity framework can drive enterprise growth by reducing friction and improving customer satisfaction, especially in sectors with stringent regulatory requirements.
