This is called Layered Security (Defence in Depth)

 

Why This Matters for Your Business

Without these protections:

  • A single phishing email can compromise your business
  • Financial fraud can occur in minutes
  • Ransomware can stop operations entirely

 

With this model, you can…

  • Protect your revenue
  • Prevent downtime
  • Safeguard customer trust
  • Meet compliance obligations (ISO 27001 / Essential Eight)
  • Gain peace of mind

Here’s a Simple Analogy

  • Training = Educated staff
  • Email filtering = Security gate
  • MFA = Locked doors
  • Endpoint = Alarm system
  • Backup = Insurance

You need all five layers to fully protect your business. They’ll prevent ~95%+ of common cyber attacks and cover all your major risk areas:

  • People
  • Email
  • Identity
  • Devices
  • Data

Take Action

Cyber attacks are no longer a matter of if, but when.
