Cyber attacks on Australian small businesses are now routine, and most start with something ordinary: a phishing email, a reused password or an unpatched laptop. IT Troubleshooter protects businesses across Southern Sydney and the Illawarra with layered security that is set up properly, monitored around the clock and explained in plain English.
Whether you run a five person office in Kogarah, a medical practice in Hurstville, a firm in the Sutherland Shire or a business in Wollongong, we tailor protection to the way your team actually works.
Cyber security services for small and medium businesses
Firewalls and network protection
We install, configure and manage business grade firewalls that control what enters and leaves your network.
- Intrusion detection and prevention (IDS/IPS)
- Web content filtering to block malicious and unwanted sites
- Secure remote access (VPN) for staff working from home or on site
- Segmented networks for guest Wi-Fi, payment terminals and medical devices
Endpoint protection: antivirus and anti ransomware
Every workstation, laptop and server we manage runs modern endpoint protection with automatic updates and central reporting.
- Malware, ransomware and spyware detection and removal
- Automatic Windows and application patching
- Device encryption for laptops that leave the office
Email security and phishing prevention
Email is still the number one way attackers get in. We harden Microsoft 365 and filter mail before it reaches your inbox.
- Spam, phishing and malicious attachment filtering
- Multi factor authentication (MFA) for every account
- SPF, DKIM and DMARC set up so criminals cannot easily spoof your domain
- Staff awareness tips so your team can spot a scam
24/7 security monitoring
Your network, servers and devices are monitored 24/7. Alerts are raised automatically the moment something unusual happens, so threats are dealt with quickly, often before anyone in the office notices.
Backup, encryption and recovery
Good security assumes something will eventually go wrong. We encrypt sensitive data and pair it with tested cloud backup and disaster recovery, so a ransomware attack or failed server becomes an inconvenience rather than a disaster.
Aligned with the Essential Eight
The Australian Cyber Security Centre recommends the Essential Eight as a baseline for Australian organisations. We use it as our checklist: application control, patching applications, Microsoft Office macro settings, user application hardening, restricting admin privileges, patching operating systems, multi factor authentication and regular backups. We will show you where you stand today and what to fix first.
Privacy obligations for Australian businesses
If your business holds personal information, the Privacy Act and the Notifiable Data Breaches scheme may require you to protect it and report serious breaches. Medical practices, law firms and accountants carry particular responsibility. Our security setups are designed to help you meet those obligations.
