Understanding GCTI assessment: a major challenge for digital trust

In a context where digital transformation is accelerating, the issue of cloud service reliability is becoming crucial for both providers and client companies. Indeed, offering a high-performance infrastructure is no longer enough; it is now essential to be able to demonstrate a high level of trust, as measured by the GCTI (Global Cloud Trust Index) assessment system.

This concept requires specific attention as it determines the credibility of European market players in terms of hosted data security and the reliability of service contracts, customer support, and infrastructure resiliency.

In this post, we take an in-depth look at our methods, evaluation criteria, and best practices for optimizing your GCTI score and thereby strengthening confidence in cloud solutions.

GCTI assessment: Definition and challenges

The B2CLOUD GCTI assessment can be defined as a quantitative and qualitative index that measures the reliability, security, compliance, and performance of a cloud service. This score is based on a set of rigorous criteria that take into account technical, financial, regulatory, and contractual aspects. It is an essential tool for companies looking for a reliable cloud service provider, but also for the providers themselves, who can use it to promote their offering and reassuring their customers.

Among the most commonly evaluated criteria are data security (encryption, access management), compliance with European standards (GDPR, ISO certifications), infrastructure resilience (availability, redundancy, SLA), and transparency of business practices (reversibility, pricing).

These factors are weighted according to their criticality levels (1 to 3) to produce an overall score, shown as a T|R rating (Transparency|Reliability).

The relevance of this score extends beyond a simple rating: it directly influences the purchasing decisions of companies seeking to minimize the risks associated with migrating to the cloud or changing providers.

How does GCTI assessment and scoring work?

The evaluation process is based on a structured methodology that includes several key steps:

1. Data collection: Cloud providers must provide information about their infrastructure, security policies, certifications, and operational practices. This data can also be collected automatically if publicly available.

2. Technical assessment: Our systems are configured to analyze and verify the information provided, including the robustness of solutions, vulnerability management, compliance with security standards, pricing, publication of service levels, and portability and reversibility commitments.

3. Regulatory assessment: Compliance with legal requirements, particularly EU requirements, is carefully monitored.

4. Scoring and verification: results are compiled and weighted to produce a final score that is regularly updated based on the completeness/accuracy of the data. (Precision and Recall)

   
   

This score is regularly updated to reflect technological and regulatory developments, as well improvements made by suppliers to their solutions.

It is important to highlight that this evaluation system is not limited to a simple one-off check, but is part of an ongoing process of improvement and transparency.

For business clients, understanding how this works allows them to better interpret the scores displayed and ask the right questions when choosing a cloud provider.

Why is the GCTI trust score crucial for suppliers and businesses?

The GCTI Trust Score plays a decisive role in the dynamics of the cloud market, as it acts as a guarantee of reliability. For providers, obtaining a good score not only strengthens their brand image, but also opens the door to new customers, particularly those with high requirements in terms of security, compliance, and transparency.

For enterprise clients, this score is a valuable tool for reducing the risks associated with cloud migration by ensuring that the chosen provider complies with best practices and current standards. It can also be used to objectively compare different offerings, taking into account criteria that are often complex to evaluate individually.

In a European context where digital sovereignty is a strategic issue, the GCTI cloud trust score helps promote local solutions that comply with European regulations and limit dependency on foreign players.

How to improve your GCTI score?

Improving your GCTI score is not just a technical process, but involves a comprehensive strategy incorporating several dimensions. Here are some practical recommendations for suppliers wishing to optimize their score:

• Enhancing security: Implementing advanced encryption, identity and access management mechanisms, as well as incident detection and response systems, data localization, and services in Europe.

• Obtain recognized certifications: ISO 27001, SecNumCloud or BSI C5, SOC 2 or 3, and other European labels or certifications that guarantee service compliance and quality.

• Ensure transparency: Communicate data management practices, offer clear contractual guarantees, and publish Service Level Agreements (SLAs).

• Invest in resilient infrastructure: ensure high availability, business continuity plans, and regular backups.

  
  

For business customers, we recommend asking for concrete proof of these commitments, regularly checking GCTI scores, and prioritizing suppliers who are committed to continuous improvement.

Towards a new era of digital trust

GCTI assessment is increasingly becoming an essential element in building trust between suppliers and customers in the European cloud industry.

By adopting a rigorous and transparent approach, it is possible to meet growing expectations in terms of security, compliance, and performance, while promoting innovation and competitiveness.

The B2CLOUD GCTI platform, as the European benchmark for trusted cloud services, plays a key role in this dynamic by facilitating connections between reliable players and companies seeking secure solutions. This development marks an important step toward a more mature cloud ecosystem, where trust becomes a real driver of growth.
