Many small businesses only learn they were vulnerable after a data leak, a scam or ransomware. A security assessment works the other way around: it checks where you stand today and gives you a list of what to fix first.

What gets checked

  1. Accounts and passwords: reused passwords, old accounts of former staff, two-step verification.
  2. Backup: whether it exists, where it is, whether there is an off-site copy and whether restore works.
  3. Updates: Windows, browsers, router, website and plugins.
  4. Antivirus and firewall: whether they are active on every device.
  5. What is exposed to the internet: remote access, open router ports, admin panels.
  6. Email: scam protection and domain configuration.
  7. Team habits: how staff react to suspicious emails and messages.

What you receive

A clear list of priorities in plain language: what is urgent, what can wait and how much effort each item takes. No unnecessary jargon.

When to do it

  • Before opening or expanding an office.
  • After hiring or letting staff go.
  • If the business has never reviewed its security.
  • After a scare (strange email, hacked account, a computer slow for no reason).
