What is it?
SaaS applications streamline operations but also introduce risk. Each SaaS tool potentially expands the organisation’s attack surface. Proper security measures ensure these platforms meet compliance standards, protect data, and operate within defined security parameters.
What could happen?
If SaaS applications are onboarded without due diligence, attackers can exploit misconfigurations, weak authentication, or unpatched vulnerabilities. Sensitive information stored in SaaS platforms can leak, subjecting the company to regulatory fines, legal liabilities, and damaged customer trust.
What to do about it?
Foundational: Perform a basic security review of new SaaS vendors, verifying their data encryption and MFA policies before rollout.
Outcome: Screens out obviously insecure providers and sets a baseline of trust.
Enhanced: Implement single sign-on (SSO) and role-based access controls for SaaS tools, ensuring that users only see what they need.
Outcome: Reduces the chance of credential theft and accidental data exposure.
Comprehensive: Integrate SaaS platforms with a centralised CASB (Cloud Access Security Broker) or SIEM solution for real-time threat detection, data classification, and automated policy enforcement.
Outcome: Achieves comprehensive oversight and rapid response capabilities, even across multiple SaaS environments.
