## Why it matters

A fraudulent message can ask a colleague to reveal a password, change a payment or open a harmful attachment.

<a id="actions"></a>

## What you can do

Protect sign-ins, configure domain settings and agree how to verify payment changes. Practise reporting suspicious messages.

## Services that can help

Device Shield supports the agreed email and account controls. Workshops help staff practise recognition and reporting; no single check prevents every impersonation attempt.

## Official reference — NIS2 Art. 21(2)(j)

> 2. The measures referred to in paragraph 1 shall be based on an all-hazards approach that aims to protect network and information systems and the physical environment of those systems from incidents, and shall include at least the following:
>
> — Directive (EU) 2022/2555 (NIS2), Art. 21(2)

> (j) the use of multi-factor authentication or continuous authentication solutions, secured voice, video and text communications and secured emergency communication systems within the entity, where appropriate.
>
> — Directive (EU) 2022/2555 (NIS2), Art. 21(2)(j)

**What this reference concerns:** A password alone is not enough: a second factor to log in, and encrypted channels for calls, video, messages and emergencies.
