Palomar submitted a form, rate, and rule filing in Massachusetts for a cyber liability product called Cowbell PRIME 100 PRO, developed in partnership with cyber insurance provider Cowbell. The filing was submitted on December 22, 2025 and was placed on file by the Massachusetts Division of Insurance on February 24, 2026.

The program is designed as a claims made and reported cyber insurance policy covering a range of cyber incidents affecting businesses, including security breaches, ransomware threats, cyber crime events, and regulatory actions. Coverage applies to claims first made during the policy period and reported to the insurer according to policy terms.

The PRIME 100 PRO policy includes several core coverage sections. These include the Cowbell Breach Fund, which covers incident response costs such as breach counsel, forensic investigation, notification expenses, call center services, credit monitoring, and public relations support following a cyber event. The policy also provides coverage for extortion threats and ransomware payments, including negotiation costs and ransom payments when approved by the insurer.

Additional protections address the replacement or restoration of electronic data, reimbursing expenses to recover or rebuild compromised systems and software, as well as business interruption coverage for lost income and extra expenses caused by cyber incidents. The policy further includes protection against cyber crime incidents, such as social engineering fraud, reverse social engineering schemes targeting clients or vendors, and fraudulent funds transfers.

The product also provides cyber liability coverage for claims alleging wrongful acts such as failure to protect personal information, failure to prevent unauthorized access to systems, or failure to notify individuals following a security breach. Coverage extends to defense costs, settlements, regulatory proceedings, and penalties where insurable by law.

A number of optional endorsements are included in the program structure, covering exposures such as cryptojacking losses, telecommunications fraud, system failure losses, ransomware sublimits, contractual damages, and website media liability. The filing also outlines additional policy provisions including terrorism coverage notices, sanctions clauses, and multiple insured related endorsements.
