Cyber Security Services Sydney
Practical cyber security for small and medium businesses.
Most attacks on small businesses are not sophisticated. They exploit weak passwords, unpatched systems, phishing emails and missing backups. Zectron puts a proven security baseline in place for every client, aligned with the Australian Government’s Essential Eight, and keeps it maintained month after month.

Why small businesses are targeted
Attackers go after small and medium businesses because they often have valuable data, regular payments and fewer defences than large companies. The most common incidents we see are email account takeovers, fake invoices and bank detail changes, ransomware, and staff credentials leaked in third-party data breaches.
The good news is that most of these attacks are stopped by getting the basics right and keeping them right. That is exactly what our security baseline does.
What our security service includes
Multi-factor authentication
MFA on email, Microsoft 365, remote access and key business systems, so a stolen password is not enough.
Email and phishing protection
Filtering, impersonation protection and SPF, DKIM and DMARC to stop spoofed emails and fake invoices.
Endpoint protection
Business-grade antivirus and threat detection on every computer and server.
Patching and updates
Operating systems and applications kept up to date, so known vulnerabilities are closed quickly.
Admin access control
Administrator rights restricted to the people and tasks that genuinely need them.
Backup and recovery
Regular, tested backups kept separate from your main systems, so you can recover from ransomware.
24/7 monitoring
Your systems are monitored around the clock, with alerts acted on before small issues become incidents.
Network and firewall security
Firewalls, Wi-Fi and remote access configured securely across your office and sites.
Staff awareness
Practical guidance so your team can spot phishing and verify payment changes before money moves.
The Essential Eight, in plain English
The Essential Eight is a set of eight mitigation strategies published by the Australian Signals Directorate (ASD) to help organisations protect themselves against common cyber threats. It is the recognised baseline for Australian businesses. Read our full Essential Eight guide.
- Application control: only approved software can run.
- Patch applications: keep software like browsers and Office up to date.
- Configure Microsoft Office macros: block risky macros from the internet.
- User application hardening: turn off features attackers commonly abuse.
- Restrict administrative privileges: limit who can make system-wide changes.
- Patch operating systems: keep Windows and macOS up to date.
- Multi-factor authentication: require a second step to log in.
- Regular backups: back up important data and test that it can be restored.

Maturity levels: where you are and where you are going
Each Essential Eight strategy can be implemented to Maturity Level One, Two or Three. Most small businesses start below Level One without realising it. We assess where you are today, take you to a solid Level One across all eight strategies, then plan the next steps based on your risk, your industry and your budget.
Assess
Start with a free cyber risk scan and a review of your current setup against the Essential Eight.
Fix the gaps
We close the highest-risk gaps first, with a clear plan and fixed pricing.
Maintain and report
Ongoing monitoring, patching and regular reviews, so your security does not drift.
Help with cyber insurance
Cyber insurers increasingly ask detailed questions about MFA, backups, patching and admin access before they will quote or renew. Because we manage these controls for you, we can help you answer insurer security questionnaires accurately and show what is in place.

Frequently asked questions
What is the Essential Eight?
The Essential Eight is a set of eight cyber security strategies published by the Australian Signals Directorate. It covers application control, patching, Office macro settings, application hardening, admin privileges, operating system patching, multi-factor authentication and backups, and is the recognised baseline for Australian businesses.
Is my business too small to be targeted?
No. Small and medium businesses are targeted precisely because they often have fewer defences. Most attacks are automated, so attackers do not need to choose you specifically to find a weak password or unpatched system.
Is cyber security included in your managed IT service?
Yes. Every managed IT client gets our security baseline as standard, including MFA, email protection, endpoint security, patching and backups. It is not an optional extra.
Can you help with our cyber insurance questionnaire?
Yes. Because we manage your security controls, we can help you answer insurer questions about MFA, backups, patching and admin access accurately.
How do we find out where we stand today?
Start with our free cyber risk scan. It checks what attackers can see from the outside, including exposed systems, email security and leaked credentials, and we walk you through the results with no obligation.
