Case study: access certification integrated with corporate identity for a technology-intensive enterprise.


Client context
Access reviews conducted via email spreadsheets; privileged roles reviewed inconsistently.
Joiners and leavers sometimes retained application roles after HR termination.
Problems encountered
Managers certified lists without seeing diff from live identity truth.
Application owners not defined for 30% of entitlements.
Evidence for auditors scattered across mailboxes.
Our approach
SCIM ingestion from identity provider; nightly entitlement harvest from target apps.
Campaigns generated diffs highlighting additions since last certification.
Suspension workflow for non-response after grace period.
Implementation measures
Piloted with finance and engineering divisions before enterprise-wide campaign.
Playbooks for application onboarding defined owner attributes required.
SIEM alerts on certification suspension events.
Technical challenges
Legacy app lacked API; CSV bridge with validation rules deployed temporarily.
High-privilege roles required secondary reviewer configuration.
Outcomes
Certification completion exceeded target in second enterprise cycle.
Dormant privileged accounts identified and removed in sample audit.
Auditor reliance increased on platform exports versus sample emails.
Holdco perspective
Certification is a process product—communications templates matter as much as connectors.
Client identity and technical environment details are anonymised. Outcomes describe operational improvements—not securities performance.
Collaboration model
Joint steering committees met fortnightly with decision logs published within twenty-four hours.
Product owners from the client had direct access to backlog prioritisation workshops.
Lessons retained
Playbooks updated after go-live incorporated lessons from hypercare tickets.
Internal Holdco knowledge base entries anonymised for future proposals.
Risk management during delivery
Delivery risks—vendor delay, key illness, environment access—tracked in RAID logs shared with steering committee.
Knowledge transfer metrics
Training attendance and runbook exercises measured before hypercare sign-off.
Post-go-live support
Thirty-day hypercare included standard; extension priced in change requests if needed.
Extended outcomes analysis
Managers completed attestation campaigns within SLA for first time after identity integration removed orphan accounts pre-campaign.
Auditors sampled exports with hash verification without requesting ad hoc screenshots.
Certification campaign outcomes
Pre-campaign identity cleanup removed orphan accounts that previously inflated reviewer workload.
Auditors validated hash exports without requesting screenshot collages from managers.
