All jobs merit a risk to meet the objectives of a company. Mostly jobs such as vendors, public relations and HR are the most likely to receive some kind of digital threat because of the large number of
emails they receive.
The best thing to protect your company, even if it is not the absolute solution … Is to isolate the departments in the company’s network to reduce the spread of the threat, but this technique involves acquiring more hardware. Another alternative may be a VLAN (Virtual LAN) without having to replace or purchase more hardware.
We also advise you to give training to all people who make daily life within those departments, so that they can identify a malicious email and avoid opening it.
