I don't think technology will be a long term solution. What I think the industry needs is tighter regulation and incentives for companies to not "move fast and break things", lest they get slapped with large fines. The issue is that I don't think the majority of politicians are informed on the social cost of, say, not serving a website over HTTPS or encrypting data at rest. Until then, this sort of thing will keep on happening because ultimately companies don't have a disincentive to do otherwise.
