Unfortunately, yes, there are additional risks that one can be exposed to in a remote workplace setting, despite that additional security that VPNs and Encrypted Software Applications provide. These additional risks can be mitigated with proper policies, and procedures within your workplace, and ongoing education for your team regarding best practices for Network Security. After all, it is well known that human error is the largest security risk in a network.
iPoint is happy to offer consultations on implementing secure practices. We also offer a Risk Assessment service that helps us (and you) know about attacks as soon as they happen.
