Berlin – November 03, 2026 -- IT service providers, software companies and SaaS vendors without an ISO 27001 certification can be dropped during supplier qualification at large clients, before price, offer or references are weighed, according to Joachim Reinke, information security expert and founder of einfachISO.
Large buyers screen vendors on formal proof before negotiations begin
Corporations and larger mid-sized companies often check suppliers against formal requirements ahead of contract talks. These include insurance, data protection rules and financial indicators, and in some cases certifications. Reinke says the costliest lost contract can be one management never learns about, because the company was filtered out before selection started.
