BRUSSELS, June 17 (Reuters) - A proposed cybersecurity

certification scheme (EUCS) for cloud services should not

discriminate against Amazon ( AMZN ), Alphabet's

Google and Microsoft ( MSFT ), 26 industry groups across Europe

warned on Monday.

The European Commission, EU cybersecurity agency ENISA and

EU countries will meet on Tuesday to discuss the scheme which

has undergone several changes since ENISA unveiled a draft in

2020.

The EUCS aims to help governments and companies pick a

secure and trusted vendor for their cloud computing business.

The global cloud computing industry generate billions of euros

in yearly revenue, with double-digit growth expected.

A March version scrapped so-called sovereignty requirements

from a previous proposal, which required U.S. tech giants to set

up a joint venture or cooperate with an EU-based company to

store and process customer data in the bloc in order to qualify

for the highest level of the EU cybersecurity label.

"We believe that an inclusive and non-discriminatory EUCS

that supports the free movement of cloud services in Europe will

help our members prosper at home and abroad, contribute to

Europe's digital ambitions, and strengthen its resilience and

security," the groups said in a joint letter to EU countries.

"The removal of both ownership controls and Protection

against Unlawful Access (PUA) / Immunity to Non-EU Law (INL)

requirements ensures that cloud security improvements align with

industry best practices and non-discriminatory principles,"

they said.

The groups said it was crucial that their members have

access to a diverse range of resilient cloud technologies

tailored to their specific needs to thrive in an increasingly

competitive global market.

Signatories to the letter include the American Chamber of

Commerce to the EU in the Czech Republic, Estonia, Finland,

Italy, Norway, Romania and Spain, and the European Payment

Institutions Federation.

Others which signed the letter include the Czech

Confederation of Industry, Denmark's Dansk Industry, Germany's

Bundesverband deutscher Banken, the Digital Poland Association,

Irish business lobby group IBEC, the Netherlands' NL Digital and

the Spanish Start-up Association.

EU cloud vendors such as such as Deutsche Telekom

, Orange and Airbus have pushed for

sovereignty requirements in the EUCS on fears that non-EU

governments may get unlawful access to Europeans' data on the

basis of their laws.
