propertycasualty360.comは安全ですか？

Site owned by Summit Business Media. Good privacy policy, very detailed. Also nice: You do not have to have cookies turned on to use most of the site. There is a marketing "feeling", rather than being a solely informational site for property-casualty insurance analytics. So some of the articles have a degree of subtle bias. But it isn't nearly as restrictive as the IDC sites which require registration to do anything or get any sort of value. I couldn't comment about vendor reliability, as I have no experience with this site as a business provider. They do sell a lot of educational products and services, and that is probably the main purpose behind the articles. But some of them are decent and quote well-regarded actuarial and BI authorities.
