First-party and third-party cyber coverage

First-party cyber pays your own costs after an attack, such as forensics, notification and lost income. Third-party cyber pays claims others bring against you for a breach, such as customers suing over exposed data.

Why it matters for your company

A cyber policy is several coverages under one limit. On the first-party side sit incident response, data restoration, extortion payments, and business interruption while systems are down. On the third-party side sit privacy liability, network security liability and regulatory defense.

For AI products the definitions decide the claim. A prompt injection that makes a model leak customer data may or may not be a security event under a form written before language models existed, and each side of the policy defines that trigger separately. Both halves need reading.
