  • Information is encrypted while it travels between your browser and our systems.
  • Only the people who need it can access it.
  • Internet addresses are scrambled (hashed) before we store them.
  • Links in our emails are signed and expire, so they can't be guessed or reused.
  • Spam protection and rate limits on every form.

If we ever have a security breach that affects your information, we'll tell you and the Information Regulator as POPIA requires.
