Why the cloud?

Despite the common doubts and mistrust that still exist, cloud infrastructures can be perfectly secure for data storage, web applications, e-commerce platforms and all IT systems. A cloud computing service offers many advantages over using an internal (on-premises) infrastructure alone.


Regardless of how you use your virtual machines, it is important to set up all the measures you need to optimise a cloud hosting solution with a hybrid infrastructure, for example. Combining a public and private cloud offers the flexibility, agility and high availability required for successful digital transformation, efficient big data processing, and the use of optimised, cost-effective machine learning applications. Whether you are a startup, a service provider or a developer, our cloud solutions can be adapted to any type of structure and usage — offering the benefits of cloud computing to everyone.

Why launch a cloud security campaign?

As a processor for data controllers, we believe it is vital to raise awareness of the importance of data security. While our solutions comply with local regulations, our customers are responsible for ensuring that their infrastructure is best adapted for their sector. To help with this, we provide support, and raise awareness of the importance of data protection and best practices for both customers and prospects. This way, they can be aware of everything they should consider when choosing their cloud provider and solutions.

This work involves campaigns such as the cloud security campaign, which helps us highlight solutions and certifications that are best suited to our customers’ needs.

What are the security risks in cloud computing?

Did you know that in 2019, the average time taken to detect a fraudulent presence was 56 days?

There are many risks, and it is everyone’s responsibility to limit them by implementing best practices and ensuring that they have a compliant, secure information system. Otherwise, the system is exposed to the risk of data leaks, IT system failures, and it could even lose its certifications. These threats not only pose a risk to the data being processed, but they also incur additional expenses to counter attacks. They can also tarnish a company’s image. This may be the case due to a GDPR breach or ransomware, for example.

How do I secure my data in the cloud?

By following best practices. These are essential for maintaining cloud security as they help you protect your infrastructure as much as possible, and minimise the risks associated with hosting and processing personal data. Here are a few examples of best practices related to cloud security.

Educate your employees about the importance of data confidentiality, so that they become one of your assets when it comes to cloud security. By keeping them prepared and alert, their involvement can help counter cyberattacks. Depending on the type of attack, they can be a gateway to these threats. Limit access to trusted IP addresses, use strong passwords and two-factor authentication. Keep an eye on infrastructure and users to detect unusual activity, and react as quickly and effectively as possible. Analyse data and traffic, monitor CPU usage and the number of connections to an internal system, evaluate network traffic to detect unusual behaviour.


It is also important to remain agile and reactive, so that you can counter potential attacks as effectively as possible. Adapting in all circumstances and reacting quickly can reduce the consequences of a cloud security breach.

Is a high-performance infrastructure a guarantee of security?

Nothing ever guarantees complete security. Despite all the measures in place to optimise infrastructure and and service security, as soon as human intervention is required for your company to function properly, there is a risk. This is why we are so keen to raise awareness of the importance of data protection. It is essential to ensure that all teams within an organisation are aware of the issues behind any kind of data processing and protection. By providing your teams with training, support, and the knowledge they need to secure both personal and customer data, you can boost your infrastructure’s security and reduce security risks in your cloud infrastructure.

Security in the cloud — a major challenge

Between 2019 and 2020, ransomware attacks increased by 311%. The drastic increase in cyberattacks shows us that security in the cloud is everyone’s responsibility, and that it is up to all of us to implement all the measures necessary to limit the risks associated with it.
As a cloud provider, we guarantee the security of our infrastructures, to provide optimal protection for customer and employee data. This reduces the risk of cyberattacks. To best prevent the threats associated with cloud computing security, we need to implement best practices — as well as access to solutions hosted in European datacentres — with certifications adapted to current challenges.


OVHcloud offers labelled solutions for all players involved in data processing. The solutions are delivered by an ecosystem of members and contributors to the Open Trusted Cloud program. These labelled, certified solutions ensure an optimal level of security and protection — and they are compliant with the regulations in force, even as they are being developed. To guarantee the cloud security you may need, OVHcloud provides infrastructures and cloud environments that are compliant with regulations. You can use our solutions to create a hybrid architecture, which strengthens your cloud protection.

In the OVHcloud Marketplace, we also offer IT solutions (SaaS and PaaS) hosted on our cloud in France, and offered by our partner sellers.

What is cloud security?

Cloud security is a set of best practices for protecting customer data, applications, systems and networks. As a cloud provider, we offer our users the most secure, compliant infrastructures possible. However, every customer is responsible for configuring and managing their cloud environment with a security level that fits their sector. By implementing the right level of cloud security, you can avoid cyberattacks, and limit the impact they can have on your company while protecting the data you store. Good security management can also help with disaster recovery.

How do you ensure the security of your data?

While OVHcloud guarantees the highest level of security for its infrastructures, customers are also responsible for taking measures to secure and protect their solutions and data. There are several ways you can do this, and they can be combined to optimise cloud security.

In particular, cloud security involves implementing best practices for protecting data and information systems (IS). The cloud provider must offer labelled solutions that comply with the regulations in force — and even better, a hybrid and multi-cloud infrastructure.

Some of the best practices include using the infrastructures of a trusted cloud provider that hosts your data in a sovereign cloud, performing regular backups and monitoring, and even hiring consultants and service providers to enhance the security of your IT services.

To ensure that your IT systems are protected, secure and available, we also recommend setting up disaster recovery and business continuity plans in addition to regular backups. You can also host and store your data with multiple service providers in different datacentres, to guarantee redundancy for your infrastructures in the event of an incident.

Cloud security, a collective approach in your organisation

The security of cloud computing is everyone’s responsibility. Each of us, at our own level, must strive to apply best practices for security. This way, we can ensure that personal data is optimally protected — whether that data is stored by our customers or employees. Firstly, we need certified and managed solutions. But to secure the data you or your customers are working with, it is important to raise awareness of how to protect data. Where human intervention is required, the risk of data leaks, ransomware or regulatory breaches increases tenfold.

A secure infrastructure is not enough. It is important to invest in data protection, so that CIOs can raise awareness of cloud security and data protection issues among executives and employees.
