That's what most IT managers tell us. Then we run a discovery — and within hours, we're showing them Dropbox, ChatGPT, Grammarly, Notion, Calendly, personal Gmail, WhatsApp Web, and a handful of browser extensions that nobody in IT has ever reviewed. All active. All connected to business accounts.
It's not malicious. Staff are trying to get their jobs done. When the approved toolset is slow, hard to use, or doesn't exist yet — people find alternatives. The problem is those alternatives often have direct access to business data, email, and calendars.
The risk isn't hypothetical. Shadow IT has been the entry point in some of Australia's biggest breaches. An employee signs up to a third-party service with their corporate email. That service gets breached. Credentials get sold. Attackers walk into your environment through the side door you didn't know existed.
