Why it matters for your company
Sublimits are how an insurer offers a coverage without taking full-limit risk on it. They show up for ransomware, funds-transfer fraud, regulatory fines, and increasingly for claims involving AI, where a policy might restore some cover but only up to a fraction of the headline limit.
A sublimit does not add money; it is carved from the main limit. When a customer contract names a limit for a specific exposure, check that the exposure is not sublimited below what the contract asks, because the certificate usually shows only the headline figure.

- Aggregate limitThe most a policy will pay for all covered claims in one policy period, however many there are. Once it is used up, the policy pays nothing more until it renews.
- Affirmative AI coveragePolicy wording or a standalone product that names AI-related losses as covered, instead of leaving them silent or excluding them. It arrives as an endorsement to cyber or E&O, or as a dedicated AI liability policy.
- EndorsementA page attached to a policy that changes it: it adds coverage, removes it, names a new party, or rewrites a definition. The endorsement controls over the base form wherever the two disagree.
- First-party and third-party cyber coverageFirst-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.
