Rbcafe nous a aidés à plusieurs reprises à trouver et à résoudre certains problèmes sur les sites web que nous protégeons. Ce type d'aide est très apprécié du point de vue de la sécurité. Nous pouvons ainsi nous améliorer et protéger nos clients. En outre, la relation établie dans le cadre d'une divulgation pleinement responsable est également très appréciée. Au-delà de la technique, nous avons également une bonne relation et une bonne confiance lorsqu'une alerte est portée à nos oreilles par Rbcafe (nous savons qu'elle est réelle et qu'il faut y répondre). Merci encore en mon nom.

Rbcafe has helped us many times to find and fix some issues on web sites we're protecting. This kind of help is greatly appreciated from a security perspective. This way we can improve ourselves and protect our customers. Moreover the relationship established in a fully responsible disclosure is also greatly appreciated. Thanks again in my name.
