Quick answer. The core RCS security best practices for a business are: send only from a verified RCS sender, get explicit opt-in and pre-approve your use cases and templates, protect your platform credentials (API keys and webhooks), enforce least-privilege access for your team, avoid transmitting sensitive data unnecessarily, monitor for abuse and unusual patterns, and keep consent and audit records. Done together, these make an RCS program both compliant and resistant to spoofing, spam, and credential abuse.
Treat the messaging platform like any other system holding customer data: rotate and scope API keys, sign and verify webhooks, restrict who can send and edit campaigns, and log everything. On the content side, lead with your verified brand so customers learn to trust the badge, and never ask for full passwords or card numbers over the channel.
SimplyRCS supports these directly: scoped API keys shown once, signed webhooks, role-based team access, verified sender setup, pre-approved content rules, and per-channel consent — so the secure path is the default path.
Key facts
- Always send from a verified agent; pre-approve use cases and templates.

- Minimize sensitive data, monitor for abuse, and retain consent/audit logs.
