SaaS firms and financial incumbents are pushing payments deeper into software flows, for example, via embedded payments. SaaS providers, particularly vertical ones, are realizing that embedding payments not only streamlines checkout for users but turns the payment plumbing into a revenue stream and loyalty lever. By turning core capabilities into API-based services, companies like FIS can monetize usage, tier functionality and embed payments elements to clients. Likewise, in the vertical SaaS space, partnerships are multiplying to embed payments directly into workflows. For SaaS models to scale in financial services, trust is critical, especially because financial SaaS often processes sensitive data, handles settlement flows and integrates with banking rails. The Cloud Security Alliance (CSA) launched the SaaS Security Capability Framework (SSCF). The SSCF defines 41 customer-facing, configurable security controls across six domains, including change control and configuration management; data security and privacy lifecycle management; identity and access management; interoperability and portability; logging and monitoring; and security incident management. By bringing standardization to how SaaS security is evaluated, the SSCF may help accelerate SaaS adoption in regulated sectors like financial services. Customers and third-party risk teams have a consistent baseline to compare offerings. Security teams get a clearer implementation roadmap.
