Practical guidance
Messaging us safely.
A few simple habits keep your enquiry as discreet as possible from the very first message.
Do
- Save our number as “CPIS Singapore” to make replies instantly recognisable.
- Use your personal phone, not a work device that may be monitored.
- Tell us if there's a window where the subject may have access to your phone.
- Mention any deadline (e.g. court date, board meeting) so we can prioritise.
Don't
- Don't send screenshots that include identifying details if your phone is shared.
- Don't message from a device you suspect has spyware installed.
- Don't share another party's confidential corporate documents without authorisation.
- Don't worry about being polished, investigators read between the lines.
If you can't safely WhatsApp us
Use a borrowed phone, or call from a quiet location.
For matters where device safety is a concern, we recommend reaching us from a trusted friend's phone or a public area. Our case desk will never out you to anyone.
