Professional liability insurance (PLI) is insurance that protects professionals such as accountants, lawyers, and physicians against negligence and other claims initiated by their clients. Professionals who have expertise in a specific area require this type of insurance because general liability insurance policies do not offer protection against claims arising out of business or professional practices such as negligence, malpractice, or misrepresentation. Coverage does not include criminal prosecution, nor all forms of legal liability under civil law, only those listed in the policy. Cyber liability, covering data breach and other technology issues, may not necessarily be included in core policies. However, insurance that covers data security and other technology security-related issues is available as a separate policy.
