What's next is better decision-making
Background checking is not just a routine step in the hiring process; it’s a strategic HR tool to make better hiring decisions.
Zellis Background Checking covers the following important background checks:
Identity & eligibility

Experience & qualifications
Validate experience and credentials to improve quality of hire and meet role or sector requirements, including employment and professional references, education and membership verifications, and gap investigation and directorship checks.
Risk & assurance
Apply the right diligence to protect your organisation, people, and reputation, including criminality DBS checks, financial probity, and fraud and sanctions screening, bias-free online and social media screening, and role-specific checks (SMCR/FCA, BPSS, PCI DSS compliance and more).
International screening is delivered with in-country experts to meet local legal, privacy and regulatory requirements (country, role and check type dependent).
