If your network uses Zyxel equipment then you need to check if it is on the list compromised equipment that needs patching.
Zyxel warns of critical vulnerabilities in firewall and VPN devices (bleepingcomputer.com)
My advice: Either you or your IT support need to check whether these issues impact your systems. You need to have a master document that details your systems, hardware, software, online, networks, back-ups, suppliers etc – so when cyber security (or operational) issues arise you and your support teams can quickly check if you are affected. From there you can take fast, effective action.
