If you are depending on a Sophos firewall then check and see that it is fully updated and patched:
Sophos fixes critical code injection bug under exploit • The Register
You of course have your Cyber Security “What is normal” document to hand, to check if this issue impacts your cyber security?
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.
