Most online business owners think security means "I use 2FA, I'm fine." In 2026, that's not the weak spot anymore. The weak spot is the abandoned plugin you forgot you installed. The browser extension that quietly reads every page you open. The connected app you authorized two years ago and never revoked. The AI API key sitting in an old project. The family member who picks up a phone call from your cloned voice. The new wave of automated attacks finds one of those — not you personally — and walks in through it.
