Mergers and acquisitions introduce multiple tenants, inconsistent controls, and inherited tools that obscure risk. Security teams struggle to see which users, apps, and vendors they’ve acquired—and where the real exposures lie. Attackers exploit these gaps through social engineering, account compromise, and vendor fraud. Legacy gateways make matters worse by requiring mail-flow changes and slowing the onboarding of newly acquired environments.
