Key Differences in Cyber Insurance

Security Platform and Optional Tiers

At-Bay says every cyber policy includes access to Stance for monitoring, vCISO advice, tabletop exercises, and training. It also describes optional InsurSec tiers with varying ransomware and fraud terms; MDR is sold separately. biBerk’s selected page gives example response and defense limits of $50,000 each for its add-on.

Primary and Excess Appetite vs Add-On

At-Bay says it writes primary and excess cyber up to stated revenue and limit ceilings, with lower ceilings for automated broker quotes; the figures are appetite limits, not guaranteed offers. biBerk’s base add-on example gives separate response and defense amounts. Ask what layer the At-Bay proposal covers and which contract carries biBerk’s sublimits. 3 9

What to Confirm in Cyber Insurance Quotes

  • Ask At-Bay which InsurSec tier and MDR subscription appear on the quote; ask biBerk whether higher response or defense limits are available. 3 9

  • Ask At-Bay which insurer issues the policy and whether it is primary or excess; ask biBerk which parent policy carries the cyber add-on. 3 9
