History being a guide, Marriott will obtain a contract with some financial security monitoring service, and offer a ~12 month free period for affected consumers. I've always thought these products are b.s. The advertising is scammy. I'm betting they leak even more data, like your purchase histories. Does anyone know of the efficacy of these monitoring services? If they were really even slightly more effective than even odds, I would say that consumer protection laws should require free monitoring for a longer period, say 24 months or even 36 months. Ironically though, proper monitoring means sharing all of this same personal information with a 3rd party, and then some. I also wonder if it's just more effective to take advantage of the free credit report freezing feature, since that doesn't require me to share even more personal information with a 3rd party; and actually restricts access to personal information instead of expanding it.
