URMRKT protects participant data and funds with industry-standard controls: encrypted transport and storage, role-based access with mandatory multi-factor authentication for staff, an append-only tamper-evident financial audit trail, segregation of participant funds from operating funds, and vendor due diligence for payment and compliance providers. Users are responsible for safeguarding their credentials and enabling available account security features. Report suspected vulnerabilities or security incidents to security@urmrkt.com; we acknowledge reports promptly and do not pursue good-faith researchers. Detailed internal controls are deliberately not published.
