To demystify perceptions about the cloud, we gathered common myths and showed how, with good practices, the cloud can be even more secure than traditional environments.

5 myths about cloud security

These myths often arise from misinformation or poorly managed experiences. To demystify these perceptions, we have gathered 5 of the most common myths and shown how, with good practices, the cloud can be even more secure than traditional environments. Follow along!

Myth 1: “The cloud is not secure”

Although widely used, the myth persists that the cloud is an unstable and insecure environment, due to the fact that data is stored outside the organization's facilities.

This myth is dispelled by the fact that major cloud providers (such as AWS, Azure, and Google Cloud) invest large sums in security and adhere to strict compliance standards.

The cloud is secure, as long as it is well managed. Vulnerability usually does not lie within the cloud itself, but in how it is used. It is essential to ensure proper configuration, constant system updates, encryption, multi-factor authentication, continuous monitoring, and other actions to reduce risks.

Myth 2: “If it's in the cloud, the responsibility is on the provider”

Many companies believe that by hiring a cloud service, all responsibility for security is transferred to the provider. In reality, there is what we call shared responsibility, which clearly defines the roles of each party.

The provider protects the infrastructure (network, servers, data centers), while the client is responsible for data, access, configurations, and permissions within the environment.

To ensure security, it is essential to understand this model, apply good governance practices, and empower teams about their responsibilities, ensuring that everyone is aligned regarding their responsibilities in protecting information.

Myth 3: “Anyone can access my data in the cloud”

This is one of the most common fears about the cloud. The idea that, because data is “on the internet,” anyone could access it makes it seem like it is public or unprotected.

In reality, data in the cloud is not accessible by just anyone. It has multiple layers of security, such as encryption, identity and access control, VPNs, firewalls, and multi-factor authentication. Additionally, major providers adhere to strict security and privacy standards, with recognized international certifications.

Access to cloud data is controlled by the company itself, and security breaches are usually linked to incorrect configurations — not to the cloud infrastructure itself. To avoid risks, it is crucial to adopt good practices, such as implementing identity and access management (IAM) policies, restricting permissions by role, using multi-factor authentication (MFA), auditing access, and training users.

Myth 4: “The cloud is expensive”

There is a perception that migrating to the cloud incurs high costs and unexpected expenses, making this option financially unviable for many companies.

In practice, the cloud offers flexible payment models that significantly reduce initial investments in hardware and maintenance. When well-managed, it allows for resource optimization, infrastructure scaling according to demand, and avoidance of unnecessary spending.

On the other hand, lack of monitoring and control can increase costs, but this can be avoided with proper practices, such as continuous monitoring of resource usage and costs, as well as correct infrastructure sizing.

Myth 5: “Migrating to the cloud is riskier than keeping everything on-premises”

Many still believe that keeping data on their own servers is safer because they are physically closer. However, the risk does not lie in the location but in the protection measures adopted.

On-premises environments without good practices can be easy targets for attacks, failures, disasters, or theft. In the cloud, however, there are continuous investments in security, encryption, automatic backups, and disaster recovery — layers of protection that are often inaccessible in local structures.

The cloud does not eliminate risks but offers more resources to manage them effectively, as long as it is well configured and monitored.

Demystifying these myths is essential to prevent misinformation from hindering companies from adopting a secure and efficient model.

The cloud can be as — or more — secure and efficient than traditional environments, as long as good practices are followed. Proper management reduces risks and enhances benefits, making the cloud a strategic ally for growth and innovation.
