Cybersecurity for small business in Perth has never been more critical. With cybercrime costing Australian businesses over $33 billion annually, small and medium businesses (SMBs) are now the number one target for hackers. If you think your business is too small to be attacked, think again — attackers specifically target SMBs because they often have weaker defences than large enterprises.

In this guide, we break down the most important cybersecurity steps every Perth business should take, explain the threats you face right now, and show you how partnering with a local Managed Service Provider (MSP) can protect your livelihood.

Why Perth Small Businesses Are Being Targeted

Perth’s business community is thriving — from trades and construction to professional services and retail. But this growth has made us a target. Cybercriminals use automated tools to scan thousands of businesses simultaneously, looking for any weakness they can exploit. They don’t care whether you’re a two-person accountancy firm or a 50-person logistics company.

The most common threats facing Perth SMBs today include:

Fraudulent emails designed to steal login credentials or trigger fraudulent payments
Phishing emails
Malicious software that encrypts your files and demands payment for their return
Ransomware
Attackers impersonate your CEO or supplier to redirect payments
Business Email Compromise (BEC)
Using leaked usernames and passwords to access your accounts
Credential stuffing
Compromising a software vendor you trust to reach your systems
Supply chain attacks

The Real Cost of a Cyber Attack on a Perth SMB

Beyond the obvious financial losses, a cyber incident causes cascading damage that many business owners underestimate:

Average downtime of 21 days following a ransomware attack
Legal obligations to notify affected customers under the Notifiable Data Breaches scheme
Reputational damage that drives customers to competitors
Lost productivity while systems are recovered

Insurance claims that can increase premiums or be denied if basic controls weren’t in place

5 Essential Cybersecurity Steps for Perth Businesses

1. Enable Multi-Factor Authentication (MFA) on Everything

MFA adds a second layer of verification — a code sent to your phone — so that even if a password is stolen, the attacker still can’t log in. Enable MFA on Microsoft 365, Google Workspace, banking portals, and any remote access tools. This single step blocks over 99% of account takeover attacks.

2. Keep All Software Updated

Unpatched software is one of the most exploited attack vectors. Enable automatic updates for Windows, macOS, Microsoft 365, and all third-party applications. Your MSP can manage patching across your entire fleet automatically.

3. Train Your Team to Spot Phishing

Your staff are both your greatest vulnerability and your best defence. Regular security awareness training — ideally with simulated phishing exercises — dramatically reduces the risk of someone clicking a malicious link. Ask your MSP about ongoing security training programs.

4. Back Up Your Data Using the 3-2-1 Rule

Maintain at least three copies of your data, on two different media types, with one stored offsite (such as in a cloud backup service). Test your backups regularly. Many businesses only discover their backups were failing when they actually need them.

5. Use a Business-Grade Firewall and Endpoint Protection

Consumer-grade antivirus is insufficient for business use. Deploy enterprise endpoint detection and response (EDR) tools that can identify and stop threats in real time, even unknown malware variants.

Staying Compliant: Australian Cybersecurity Obligations

Australian businesses have legal obligations under the Privacy Act 1988 and the Notifiable Data Breaches (NDB) scheme. If your business holds personal information and suffers a data breach, you may be required to notify affected individuals and the Office of the Australian Information Commissioner (OAIC). Fines for non-compliance can reach hundreds of thousands of dollars.

An MSP can help you establish data handling policies, conduct risk assessments, and ensure you have the documentation needed to demonstrate compliance.

Next Steps for Your Perth Business

Cybersecurity doesn’t have to be overwhelming. Start with the basics — MFA, patching, backups, and staff training — and build from there. A trusted local MSP can take most of this off your plate so you can focus on running your business.
