roadmap for strengthening SaaS governance
1.The Challenge
Rightmove’s SaaS environment had grown rapidly as the organisation expanded its use of cloud applications.
With dozens of critical systems in daily use, visibility had become fragmented, making it harder to:
track who had access to what
monitor third-party integrations
identify high-risk or unused applications
prevent potential data exposure
The security team needed a clear, consolidated view of the SaaS landscape and practical guidance to tighten controls.
2. Our Approach
Peritus delivered a structured SaaS security assessment focused on improving visibility, identity hygiene, and governance.
Our work included:
Full discovery of SaaS applications, accounts, and integrations
Review of authentication methods (SSO, MFA, password use)
Mapping of user access, admin roles, and privilege levels
Identification of shadow IT and high-risk connected apps
Assessment of data-sharing, file-sharing, and external access
Prioritised remediation plan with clear next steps
This gave Rightmove a single, accurate picture of risk across their SaaS ecosystem for the first time.
3. The Outcome
Peritus helped Rightmove significantly uplift their SaaS security posture, delivering:
A 52% reduction in SaaS-related attack surface
Identification and removal of unused and high-risk apps
Stronger identity and access controls across key systems
Standardised use of MFA and improved authentication pathways
A clear, actionable roadmap for continuous SaaS governance
Greater confidence in how cloud applications are secured and managed
