Security teams are increasingly using automation solutions to enhance response times, requiring secure and efficient methods for sending and reading emails. Traditional email protocols like SMTP are considered outdated and insecure, prompting a shift towards using APIs, which offer greater security and control. For organizations using Microsoft Office 365, Tines provides a solution allowing emails to be sent and read securely via the Graph API, eliminating the need for service accounts. This involves setting up Azure Active Directory with specific permissions and configuring Tines to send and read emails through API calls, thereby maintaining control over email origins and content while adhering to least privilege principles. Although this method isn't foolproof and lacks current support for encryption via Microsoft Information Protection, it significantly mitigates risks by keeping sensitive data within the organization's control.
