More Connecticut Cybersecurity Laws to Be Aware Of
Beyond these major laws, certain Connecticut industries, including healthcare, insurance, and manufacturing, have heightened cybersecurity requirements due to the state’s emphasis on data protection and privacy.
Connecticut is home to one of the nation’s most active cybersecurity governance structures, led by the Connecticut Cybersecurity Task Force and the Department of Emergency Services and Public Protection (DESPP). These entities collaborate with private companies to improve resilience, share threat intelligence, and promote security education.
Businesses in Connecticut should perform regular cybersecurity risk assessments, review their data retention policies, and ensure that third-party vendors meet equivalent security standards.
