Tessian is a London based Artificial Intelligence communication security company that prevents threats related to enterprise email communication. The company uses machine learning and natural language processing to combat threats like spear phishing, misaddressed emails, unauthorized emails, and non-compliance. Tessian’s service minimizes the human element of making mistakes while handling emails in work environment.
Emails are the most accessible form of communication for companies and employees are vulnerable to phishing attempts. US Government report shows business email has compromised over 12 billion dollar due to scams from October 2013 to May 2018. The traditional way of preventing phishing using legacy rule-based systems like cross-referencing IP addresses, verifying SPF, DKIM, and DMARC is not enough to prevent strong-form impersonation attacks for large corporations. There are numerous ways rule-based firewalls can be subverted, and these rules add overhead causing delays and catch many false positives.
Tessian first started using machine learning to secure outbound emails only. Tessian started securing inbound emails as well when they launched Tessian defender on September 13, 2018.

For preventing scams and phishing, Tessian compares it with historical contacts, analyzes the content and characteristics of inbound email using natural language processing to prevent it from reaching the inbox.
