Secure Document Exchange and Electronic Approval Portal! Exchanging sensitive and confidential information with clients is an important part of your daily routine, with a number of challenges: Email is insecure. Postal Mail is slow and has ever increasing costs. Consumer file sharing sites are complex to manage for multiple clients, and do not always comply with UK data protection requirements. SecureSpace is a safe, simple and secure collaborative tool for firms and clients to share documents with each other and get client approval electronically.
