We make security and privacy protocols part of our culture. From the moment they're hired, our employees must sign and follow several policies including our code of ethics, acceptable use policies and non-disclosure agreements. During onboarding, they undergo a mandatory five-step training program.
Through the use of our own proprietary annotation and communication tools, we control every aspect of how data is handled by our annotators. Email and internet is restricted. Information access is restricted or authorized based on project and job function.
To protect data from external attacks, we isolate secure computers from the outside area, disable installation of programs, and severely limit internet usage. All computer ports are blocked and printing is disabled. To assure this standard is maintained, we periodically run penetration tests and undergo external security audits.
