Is your business network truly secure? We audit, protect and monitor your systems against modern cyber threats.
Computer & Network Security
Here's exactly what our technicians do when you book a Computer Network Security service with ErrorFix4U.
Security Audit
We conduct a full assessment of your network — router settings, connected devices, open ports, and firewall rules — to map your current security posture.
Router Hardening
We update router firmware, change default admin credentials, disable WPS, close unnecessary ports, and enable proper firewall rules.
Network Segmentation
We set up guest and IoT networks to isolate smart home devices and visitors from your main network and sensitive devices.
Endpoint Protection Review
We verify that all computers and devices on the network have up-to-date antivirus, enabled firewalls, and current OS patches.
VPN & Encryption Setup
We configure VPN access for remote work and verify that all wireless traffic is protected with WPA3 or WPA2 AES encryption.
Security Report & Recommendations
We provide a written summary of vulnerabilities found, fixes applied, and any further recommendations to maintain your security.
Rather than one page per town, we've brought the whole Adelaide Hills region together here — get in touch from anywhere on this list and we'll organise the best way to help, whether that's dropping your device to us or a remote fix.
