Tidelift by Tidelift

Of all the companies in this space, Tidelift is the only one I could describe as uniquely ethical. If you're tired of shoveling your CVE scanner results into open source backlogs, never to be fixed, working with Tidelift allows you to actually work with maintainers to get your issues fixed upstream - while checking the box on standard SCA feature sets (plus a few unique package health assessments).
