The email contained a form of malware such that if a file in the email was opened, the entire company would be infected by ransomware, its data compromised and exfiltrated, with the concomitant costs and embarrassing headlines.

Next generation online protection.

Security starts here

How do over 90% of cyber attacks start?

With a phishing email. Ransomware, malware, financial fraud. All from phishing emails. These emails are getting more sophisticated, and the tools available just can’t keep up. These tools grew out of the anti-spam world of the 90’s and are generally rule-based, slow to respond, require massive servers, and are ill-equipped to deal with modern threats. Attackers are agile: leveraging automation, artificial intelligence and machine learning.
