WSJ:

Nearly a dozen technology companies said they will provide free or reduced-cost cybersecurity services to presidential campaigns, which experts and intelligence officials have warned are ripe targets for intrusion and disinformation.

They join a growing number of firms offering protection on a nonpartisan basis, a trend that has gained steam in the past 18 months or so, since federal regulators eased rules to make such offers permissible under campaign-finance laws. The Federal Election Commission made policy changes after urging from nonprofits and technology companies, including Microsoft Corp.

Campaigns have struggled to make their information more secure in part because of budget pressures and the fast-moving nature of a campaign.
