Why is Shield shutting down?
Shield is winding down because it ran as a Chrome extension that pulled LinkedIn data in the background, which put it in conflict with LinkedIn's API requirements and Google's Chrome Web Store policies. As Shield's co-founder put it, Google and LinkedIn made it clear they could not keep operating Shield as it was built. The same enforcement wave hit Apollo.io and Seamless.ai in 2025. Shield had been running since 2018, so this is a platform decision, not a product failure.
