Cloud cybersecurity: the 4 mistakes 80% of companies still make

The cloud offers unmatched flexibility, but it also multiplies attack surfaces.

The cloud offers unmatched flexibility, but it also multiplies attack surfaces. In 2026, cloud-related security incidents rose by 35% compared with the previous year. The good news: the majority of these incidents are avoidable.

Mistake no. 1: IAM permissions that are too broad

The principle of least privilege remains the foundation of cloud security, and yet it is rarely applied properly. IAM roles with AdministratorAccess permissions handed out widely, access keys that are never rotated, root users used day to day: so many doors left open to intrusions.

Mistake no. 2: neglecting encryption at rest

Encryption in transit (HTTPS) is now standard. But encryption at rest — databases, storage volumes, snapshots — is still neglected by many organisations. In the event of a data breach, it is the difference between a manageable incident and a GDPR disaster.

Mistake no. 3: no real-time security monitoring

Without proactive monitoring, intrusions go unnoticed for weeks, even months. Tools such as AWS CloudTrail, GuardDuty and Security Hub have to be enabled and connected to an alerting system. At Premaccess, our Ultimate BAM offer includes an automated Security Checker and a native audit trail.

Mistake no. 4: no incident response plan

An incident will happen — it is a question of time, not of probability. Companies without a structured response plan take on average 3 times longer to contain a breach. Isolation procedures, crisis communication, immutable backup, tested restore: everything has to be prepared beforehand.
