Immunising against the spear phishing plague

Email has become the primary tool of communication for organisations, both within the business and externally with customers and third parties. But with this proliferation, email has also been tirelessly exploited by sophisticated cyber-criminals. With no security authentication built in, there is a fundamental flaw in the architecture of email that means anyone can send a message pretending to be from another person or brand. More worryingly, illegitimate emails are carefully formulated, well written, seem to come from a trusted source and relate to actual issues making it very difficult to tell sophisticated phishing emails apart from their genuine counterparts.
