Frequently asked questions

What is network segmentation?

It is the practice of splitting a network into separate zones so a breach in one zone cannot easily spread.

Do you manage existing firewalls?

Yes. We can take over management of most business-grade firewalls or recommend replacements if needed.

Can segmentation help with compliance?

Yes. Segmentation supports the ACSC Essential Eight and helps meet PCI DSS requirements for card payments and the Privacy Act 1988 obligation to take reasonable steps to protect personal and health information.

Will segmentation slow down the network?

No. Properly designed segmentation does not impact performance and often improves it by reducing unnecessary traffic.

Part of our Cybersecurity services

Several layers of protection, on the sensible assumption that any one of them will have a bad day eventually. Software on every computer watches for odd behaviour, and can stop an attack and undo the damage. For businesses that need more, specialist analysts look for intruders the software missed, and only approved programs are allowed to run. It's all monitored and patched from one place, and when something needs your attention, it's Kelly or Carisa who rings you.

AI-Powered Endpoint Detection & Response
An autonomous AI engine on every device watches behaviour in real time, detecting and stopping ransomware, malware, and fileless attacks that signature antivirus can't see. Far beyond traditional antivirus.
Autonomous Threat Remediation
Threats are contained and removed automatically, without waiting for someone to notice an alert. An infected computer can be cut off from the network quickly, so one bad click stays one bad click.
Ransomware Rollback
If ransomware does get going, affected files can often be rolled back to how they were before the attack. That turns a disaster into a very annoying afternoon.
