Everyone is at risk from email fraudsters.
Sendmarc has developed an algorithm that rates an organisation’s exposure to fraudulent email activities such as impersonation, phishing and spoofing, and the risk their current domain poses to the cyber security of their company. A score between 0 and 5 is assigned to an organisation.
5 – A score of five (5) indicates a company has a very low risk of their name being used by criminals in fraudulent email activities. Domains with a score of 5 are 100% DMARC compliant and are protected from impersonation and phishing attacks.
4 – A score of four (4) requires one more change. Deliverability of rightful email may be affected by being sent to spam or junk folders and savvy criminals could impersonate your domain.
0-3 – A score of three (3) or less indicates no protection at all of their name, and the highest probability that their name will be hijacked by criminals and used in fraudulent email activities.
