Twilio has released a new security whitepaper that outlines the company's security measures, including updates to its SSL certificate and introduction of a Secondary Auth Token to help switch to new credentials in case of a compromise. The whitepaper also discusses the use of API keys for managing credentials, a new platform feature called Monitor for tracing and auditing lifecycle events, and recommendations for companies to re-evaluate their security implementations as their business grows. Twilio is committed to maintaining the highest level of security possible and encourages users to review the revised whitepaper and conduct a security audit with them. The company also has plans to release MPLS in early access for SIP trunking in the near future.
