Securing AI: the new risks every business should know in 2026

20 February 2026 Β· Lumen MSP

As AI tools become part of everyday work, they bring new security questions: staff feeding sensitive data into public tools, AI-generated content being trusted too readily, and attackers using AI to craft sharper, more convincing scams. Industry analysts now rank AI-related risk among the top security concerns for the year ahead.

The good news is that the defences are largely familiar β€” the principles haven’t changed, even if the tools have.

Why this matters

  • Shadow AI leaks data β€” staff using public tools with company information.
  • AI sharpens attacks β€” phishing and fraud are more convincing than ever.
  • Trust must be earned β€” AI output needs checking, not blind acceptance.
  • Old defences still apply β€” policy, the right tools, MFA and training.

What we’d advise

We help clients adopt AI safely: choosing business-grade tools with proper data controls, setting simple guardrails, and training staff so the productivity gains don’t come with hidden exposure.
