Contact & Responsible Disclosure

Best security disclosure practice in this group

SumUp publishes a **valid security.txt** (expires 2035), a PGP key, a general security contact and a **paid private HackerOne bug bounty** — the strongest disclosure posture of the payments firms reviewed here.

⚠️ **Read the certification block carefully.** PCI PTS, EMV Level 1 & 2 and ISO 9001:2015 appear in a **product-conformity list** alongside CE and UKCA declarations for specific hardware (Air, 3G+, Solo, Terminal, POS Lite). These are device certifications; the ISO 9001 scope is most likely manufacturing quality rather than corporate operations.

**No ISO 27001 or SOC 2 evidence found.** UK entity SumUp Payments Limited, company 07836562, authorised under the **Electronic Money Regulations 2011, register number 900700**.
