Your qualification criteria are usually about the company: under 200 employees, in manufacturing, based in the DACH region. Your filters, until now, could only see fields on the lead record — so those criteria had to be copied onto every lead by an enrichment first.
Filters now reach through to the company behind the lead. Build a segment on company size, industry, country, or any company field directly, and it stays correct as company data is refreshed by actualization.
That removes a whole class of enrichment steps whose only job was copying company attributes onto leads so they could be filtered.
