Kudosity: sovereignty score and 8 European alternatives

Kudosity is a business messaging service covering SMS, MMS, WhatsApp, RCS and conversational AI. Organisations use it to send bulk campaigns and real-time transactional messages, run two-way conversations and resell it as white label. Developers use a REST API with SDKs for Python, JavaScript and PHP, and there are integrations with products such as Salesforce, Oracle and Zoho. The platform is delivered as SaaS and grew out of Burst SMS, which was rebranded as Kudosity in 2023.

Kudosity is a trading name of Known Pty Ltd, a private company in Sydney, Australia. No foreign owner is known; the privacy policy only mentions an unnamed ultimate holding company. The policy names no data centre locations: data may be stored and processed outside the EEA, with standard contractual clauses as a safeguard. For GDPR purposes Known Pty Ltd acts as controller for the data covered by the policy, and customer data is subject to a separate data processing agreement. It reports ISO 27001 and SOC 2 Type II. European organisations should confirm the data location first.

Why digital sovereignty matters with Kudosity

Kudosity is headquartered in AU, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.

Kudosity hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Kudosity is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Kudosity together with your other vendors and gives a total score, a heatmap and the main risk drivers.
