Small businesses are frequent targets of cyberattacks because they often have fewer defences. The good news: a set of basic measures stops most attacks.

Accounts and access

  1. Multi-factor authentication (MFA) for email, cloud services, VPN and admin accounts.
  2. Password manager for unique, strong passwords.
  3. Least privilege: staff only get access they need; separate admin accounts.

Devices and software

  1. Automatic updates for operating systems, browsers and applications.
  2. Endpoint protection on all computers.
  3. Device encryption for laptops and phones.
  4. Inventory of all devices and software.

Data

  1. Backups following the 3-2-1 rule, including an offline or immutable copy, with regular restore tests.

Email and web

  1. Email security: spam and phishing filters, SPF/DKIM/DMARC for your domain.
  2. Secure websites: HTTPS, updates and monitoring.

People

  1. Security awareness training: recognising phishing, handling suspicious emails and reporting incidents quickly. Most attacks start with a human mistake.

Preparation

  1. Incident plan: who to call, how to isolate affected systems, how to restore, when to inform authorities (GDPR breach notification) and customers.

Network

Firewalls, separate guest Wi-Fi and secure remote access complement these measures.

Start with the biggest risks

MFA, backups and updates provide the most protection for the least effort.

We help SMEs implement these measures – from email security and backups to network protection and onsite device setup.
