This solution effectively bridges the gap between HR systems and IT infrastructure by synchronizing identity data with platforms like Active Directory (AD), Entra ID, Okta, and Google Workspace. By ensuring that user access and privileges are consistently aligned with their roles within the organization, Hire2Retire enhances overall operational efficiency. Targeted primarily at mid to large, fast-growing organizations, Hire2Retire addresses the challenges associated with manual and fragmented lifecycle management processes. Traditional methods of onboarding and offboarding can be slow, error-prone, and resource-intensive, often leading to security vulnerabilities, compliance risks, and diminished employee experiences. By automating these processes, Hire2Retire not only streamlines operations but also significantly reduces operational overhead, allowing organizations to focus on more strategic initiatives. One of the standout features of Hire2Retire is its extensive integration capabilities. With connections to 27 HR and Applicant Tracking Systems (ATS), major identity providers, and over 10 leading service management platforms such as ServiceNow, Salesforce, SolarWinds, and FreshService, the solution enables seamless identity orchestration. Its robust library of connectors allows for the automatic provisioning and deprovisioning of access to third-party applications based on profile-driven entitlements, making it a scalable and flexible IGA solution that adapts to the needs of modern enterprises. From a governance and security standpoint, Hire2Retire enforces role-based access control and continuously aligns user privileges with their job functions. This ensures that employees have the right level of access at all times, reducing the risk of over-provisioning. Additionally, timely deprovisioning during terminations or role changes helps prevent unauthorized access, protecting the organization from potential security breaches and reputational risks. Hire2Retire supports organizational compliance with key regulatory frameworks and standards including SOX, HIPAA, ISO 27001, and GDPR, providing complete audit trails for every identity lifecycle event.
