Convincing phishing messages
Fake sign-in pages, shared-document alerts and supplier messages can look routine. One rushed click may expose a password or start a malicious download.

Cyber Security Perth Businesses Can Understand and Use
A small business does not need a wall of dashboards or a long list of products it cannot manage. It needs sensible controls around the places an incident is most likely to begin: email accounts, administrator access, unpatched computers, unsafe network settings and backups that have never been tested.
Microsys reviews those areas in the context of your business. We look at who needs access, where your information lives, which systems would stop the business if they failed, and what protection is already in place. You receive a prioritised explanation of what should be fixed first, what can wait and why.
Our recommendations draw on the Australian Cyber Security Centre's small-business guidance, but the conversation stays practical. The aim is to reduce avoidable risk and make recovery more realistic—not to sell fear or promise that any system is impossible to breach.

Where problems begin
Security Gaps That Put Small Businesses At Risk
Most businesses do not have one dramatic weakness. Risk builds when several ordinary gaps are left open at the same time.
Hijacked business email
A criminal inside a mailbox can study real conversations, imitate payment instructions or redirect an invoice. The request looks credible because it comes from a genuine account.
Ransomware and malicious software
Malware may steal information, disrupt devices or encrypt shared files. Prevention matters, but a realistic recovery plan is just as important when business data is at stake.
Passwords without a second check
A reused or stolen password should not be enough to open business email. Multi-factor authentication adds an important barrier, particularly for Microsoft 365 and administrator accounts.
Missed security updates
Old operating systems, browsers, applications and network equipment may contain known weaknesses. A repeatable update process is safer than relying on each person to remember.
Default network settings
Old router passwords, poorly separated guest Wi-Fi and unreviewed firewall rules can create unnecessary exposure inside an otherwise well-run office.
Backups that only look healthy
A green status is not the same as a successful recovery. Backups need suitable access protection and occasional restore testing, especially for critical business information.
Too much access
Shared credentials, unnecessary administrator rights and accounts left active after staff depart make it harder to control who can reach sensitive systems and data.
No plan for a suspicious event
Staff should know who to contact and what not to do when a device behaves strangely or a payment request looks wrong. A fast, calm response can limit further damage.

How We Approach a Security Improvement
Good security work should leave you with fewer unknowns, not a bigger pile of jargon.
1. Understand the business
We identify the systems, people and information that matter most before recommending technical changes.
2. Review the current controls
Accounts, devices, Microsoft 365, network settings and backups are checked within the agreed scope.
3. Rank the findings
Critical or easy-to-exploit gaps come first. Lower-priority improvements are separated so the plan stays manageable.
4. Agree on the work
You decide what to address now. Defined projects can be quoted before implementation begins.
5. Implement carefully
Changes are planned around business use, with attention to access, interruptions and the people affected.
6. Keep responsibilities clear
For ongoing support, we document which recurring security tasks are included and which remain with your team.

Cyber Security FAQs
Straight answers about scope, protection, recovery and the difference between one-off and ongoing support.
The scope depends on your systems, but a useful review normally covers user accounts and administrator access, multi-factor authentication, Microsoft 365 settings, computers and updates, endpoint protection, firewall and Wi-Fi configuration, backup arrangements and staff security practices. Microsys explains the important gaps first and provides practical next steps.
Microsys can help strengthen Microsoft 365 access with multi-factor authentication, cleaner administrator permissions, account reviews and sensible sign-in practices. The exact work depends on your Microsoft 365 plan and current configuration.
No. Endpoint protection is useful, but it cannot compensate for weak passwords, unpatched software, poorly configured accounts, unsafe email habits or unreliable backups. Better protection comes from several sensible controls working together.
Important measures include prompt security updates, multi-factor authentication, configured endpoint protection, restricted administrator access, phishing awareness and backups that are isolated where appropriate and tested for recovery. No provider can promise that an incident will never happen, so recovery planning matters too.
Yes. Backups do not stop an attacker getting in, but they can make recovery from ransomware, accidental deletion or device failure far more manageable. A backup should be monitored or checked, protected from unauthorised access and periodically tested, rather than assumed to be working. See our data backup and transfer service for more detail.
Yes. Microsys offers ad-hoc security and IT work as well as ongoing managed IT services. A one-off review or improvement project can suit businesses that need specific gaps fixed, while an ongoing plan is better when regular checks and support are required.
Act quickly. Stop using the affected account or device for sensitive work, disconnect a suspected infected computer from the network if it is safe to do so, and contact an IT professional. Avoid deleting evidence or wiping the device before the situation has been assessed.
Microsys IT and cyber security support starts from $150 per hour and is billed in 30-minute increments. Defined work such as a security review can be scoped and quoted before work begins. Larger or ongoing requirements are priced according to the agreed services.
