Practice Areas

Sian Schafle is a Partner in Mullen Coughlin’s Incident Response practice group. Ms. Schafle focuses her practice on the representation of entities that have suffered or may have suffered a data security event. When a potential data security event has occurred, Ms. Schafle assists clients in investigating and responding to the event. As part of this representation, she often works with law enforcement and independent forensic experts to identify the nature and scope of a data security event. Ms. Schafle works with clients directly to determine the impact of the incident on the client’s business; manner in which the potential intrusion occurred; identification of the individuals whose information may have been impacted; determination of the state, federal and foreign privacy laws governing the client’s notification obligations arising from the incident; and preparation of legally compliant notifications to affected individuals, affected entities, and appropriate regulators. Ms. Schafle also defends clients against third-party and regulatory actions arising from data security events including investigations by the Office for Civil Rights, the Federal Trade Commission, and Multi-State Attorney General Collation actions.

In addition to post-data privacy and network security event services, Ms. Schafle provides pre-data security event services, including document preservation, assessment of a company’s forensic and legal vulnerabilities, and assessment and development of data privacy policies and procedures and Incident Response Plans. Ms. Schafle also provides industry-specific recommendations for proactive measures to address and mitigate risk. As part of her pre-data privacy and network security event services, Ms. Schafle also assists clients in developing and implementing in-house compliance and training programs.

Sian is also the Chief Diversity Officer at Mullen Coughlin, overseeing the firm’s Diversity, Equity and Inclusion (DEI) initiatives along with the firm’s DEI volunteers, to proactively reinforce the firm’s belief of strength in diversity.

Ms. Schafle is a frequent lecturer on data privacy and network security matters. Prior to her employment as a Breach Coach, she served as an Assistant District Attorney trying more than 30 felony jury trials and over 100 felony bench trials.
