Cybersecurity Risk Management, Strategy, and Governance [Line Items] |
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | We have a cybersecurity risk management program consisting of policies and procedures for assessing, identifying, and managing material risk from cybersecurity threats, and we have integrated these policies and procedures into our overall risk management systems and processes. Our cybersecurity policies and procedures are based on recognized frameworks established by the National Institute of Standards and Technology, the International Organization for Standardization and other applicable industry standards. We routinely assess material risks from cybersecurity threats and regularly assess and update our cybersecurity risk management program in response to emerging trends and changes in our operations. Our risk management program includes, among other elements: Identification: We aim to proactively identify sources of risk, areas of impact, and relevant events that could give rise to cybersecurity risks, such as changes to our infrastructure, service providers, or personnel. Assessment: We conduct periodic risk assessments to identify cybersecurity threats. We also conduct likelihood and impact assessments with the goal of identifying reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks. Management: Following our risk assessments, we design and implement reasonable safeguards to address any identified gaps in our existing processes and procedures. Our employees participate in cybersecurity training and awareness upon hire and at least annually thereafter. We engage third parties, including consultants and auditors, to evaluate the effectiveness of our risk management program, control environment, and cybersecurity practices through security audits, penetration testing, and other engagements. We have processes in place to identify, review and evaluate cybersecurity risks associated with our use of third-party service providers. These reviews are conducted at onboarding and periodically throughout the tenure of the service provider based on risk tier rating of each service provider. We believe these processes enable us to evaluate a third-party service provider’s security posture, identify risks that may arise out of our use of the third party’s service, and make decisions regarding acceptable levels of risk and risk mitigation. For additional information regarding whether any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect our company, including our business strategy, results of operations, or financial condition, please refer to Item 1A, “Risk Factors,” in this annual report on Form 10-K.

The updates also include significant legal and legislative developments concerning data privacy and security, our approach to complying with applicable law, and significant engagement with regulators concerning data privacy and cybersecurity. Our audit and risk committee provides regular updates to the board of directors on such reports.
