Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Cybersecurity Risk Management At Goosehead, cybersecurity risk management is an integral part of our overall enterprise risk management system. Our cybersecurity risk management program is modeled after recognized data protection principles, such as the National Institute of Standards and Technology’s Cybersecurity Framework (NIST CSF) and the National Association of Insurance Commissioners (NAIC) Data Security Model Law. These and other industry best practices provide the framework for identifying, monitoring, assessing and managing cybersecurity threats and incidents, including threats and incidents associated with the use of applications developed, and services provided, by third-party vendors and service providers, and facilitating coordination across different departments of the Company. Our cybersecurity team, led by our Director, IT Security & Compliance, is responsible for assessing and maintaining our cybersecurity risk management program. We also have a cybersecurity committee, comprised of cross- functional key business and technical leaders in the Company as well as the heads of our legal, governance, risk and compliance functions. The cybersecurity team identifies and assesses material cybersecurity risk by performing internal audits against cybersecurity controls and through regular consultations with, deliberation by, and recommendations from, our cybersecurity committees. Our cybersecurity team and cybersecurity committees utilize various tools and services designed to identify, monitor, assess and manage actual cybersecurity risk, including risks from cybersecurity threats associated with the use of third-party vendors and service providers. The cybersecurity team manages and maintains a risk register, incorporates risk mitigation items within our cybersecurity plans, conducts periodic reviews (primarily through our cybersecurity committees) of our mitigation and progress, and utilizes a third-party security risk management program both to screen third-party vendors and service providers prior to onboarding and to periodically re-evaluate existing third-party vendors and service providers based on risk classification. Our cybersecurity program includes steps for assessing the severity of a cybersecurity threat or incident, identifying the source of a cybersecurity threat or incident (including whether such cybersecurity threat or incident is associated with a third-party vendor or service provider), implementing cybersecurity countermeasures and mitigation strategies, and informing management and our board of directors of material cybersecurity threats and incidents. The cybersecurity team also conducts regular vulnerability assessments, and our cybersecurity and risk management teams perform annual risk assessments. We utilize a third party to conduct regular risk assessments of our new and existing third-party vendors and service providers and a separate vendor performs penetration testing annually. All users of our information systems receive regular cybersecurity awareness training, and our cybersecurity team provides annual training to all employees.
