What it means
SSPM examines the security configuration and access posture of software-as-a-service applications. The cloud provider runs the service, while the customer still chooses many tenant settings, identities, integrations, and sharing policies. Relevant checks can include administrator access, sign-in requirements, external sharing, and application permissions. Coverage depends on each service’s APIs and the assessment tool’s access. A finding should connect a specific setting to an organizational policy and an owner. The presence of a check does not mean the tool can enforce it or assess every tenant activity.
AN ILLUSTRATIVE SCENARIO
A school’s collaboration tenant permits broad sharing
A school district wants staff to collaborate externally without exposing student information. A posture review finds that one application allows unrestricted public sharing links. The team checks existing workflows, pilots a more appropriate default, and documents how staff can request approved exceptions. They also examine connected applications with powerful access. The provider’s security certifications do not decide whether this district’s sharing choices fit its data and users.
Put it to work
- Inventory important SaaS tenants, administrators, and connected applications. Establish who owns configuration decisions and which organizational policies apply to each service.
- Use documented assessment permissions and relevant baselines. Confirm what the connector can inspect, how current its results are, and which checks require manual review.
- Pilot changes with representative users, monitor their impact, and document exceptions. Recheck after application updates, new integrations, and major changes in access or sharing.
How to check your work
Test a known tenant setting and a representative sharing workflow. Confirm that the assessment notices drift, the intended audience can still collaborate, and an unauthorized recipient cannot use the prohibited sharing path.
