Process efficiency

Bring immediacy to processes involving sensitive data

The inefficiencies of time, cost, and carbon associated with paper-based processes are no longer justifiable to stakeholders.

Regulatory compliance

Are your emails compliant?

The FCA and the ICO advise that all personally identifiable information should be encrypted when sent off site. Email was the number one cause of data leaks in the UK in 2021. This should make it your first priority for outbound data security. Comply with regulatory guidance and protect valuable information.
