Key Differences in Cyber Insurance
Risk services before and after placement
Aon describes cyber claims advocacy and preparation and relationships with incident-response providers, whose contracts are separate and may involve referral compensation. Lockton pairs placement with cybersecurity posture reviews, incident-response exercises, security governance and cyber-hygiene policies through its Inform, Improve, Insure approach. Buyers should compare who performs each service and whether it is included, since service descriptions do not establish policy benefits or vendor contracts. 3 7
Industry focus and contact path
Aon describes cyber services for organizations managing risk without publishing a detailed industry schedule. Lockton highlights technology sectors including software, telecom, semiconductors, medical equipment and internet businesses, and directs buyers to a named cyber leader or team email rather than self-service quoting. A technology buyer can assess Lockton’s specialist fit, then ask either broker for the insurer and tailored coverage terms. 3 5
