Quantum is a security firewall that blocks access to specific websites or IP addresses. It can also be used to store data on a nas storage device or data cartridge. Tape drives are also able to store data on a Quantum security device. When using a Quantum security firewall, it is important to ensure that all devices that will be accessing the internet are properly configured. This will prevent unauthorized access to the website or data that is being protected. Additionally, all data that is being stored on a Quantum device should be regularly backed up to ensure that it is not lost in the event of a power outage or other disaster.
