Cloud infrastructure has long become a standard for modern companies. It scales, simplifies operational processes, and removes part of the technical risks. Along with this, a dangerous illusion has emerged: if a system operates in the cloud of a large provider, it is automatically secure. In reality, the cloud does not remove responsibility – it only changes its form.
The shared responsibility model means that the provider is responsible for the physical infrastructure and the base platform, while everything related to configurations, access controls, integrations, and business logic remains on the company’s side. It is precisely in this area that most real threats arise. Therefore, the question is not even whether you need cloud penetration testing services, but when ignoring it becomes a critical risk.
The illusion of security in the cloud and its consequences
Most companies do not ignore security – on the contrary, they actively use available tools. The problem is that these tools often create a false sense of control. Built-in security mechanisms, compliance with standards, and the absence of incidents appear to confirm reliability, but they do not reflect the real picture.
Most often, this misconception is formed by the following factors:
- The belief that the cloud provider’s built-in security services cover all risks.
- Equating compliance with resilience to real attacks.
- Relying exclusively on automated scanners and configuration checks.
- A long absence of incidents as an argument that “everything works for us.”
In practice, most cloud attacks do not look like a sudden breach or the exploitation of a “critical vulnerability.” Instead, they involve the sequential abuse of permitted but improperly restricted system capabilities.
Real threats to cloud infrastructure
Cloud attacks are almost always scenario-based. They arise at the intersection of access controls, services, and the logic of interaction between components. A single misconfigured IAM policy may not be a problem on its own, but combined with an exposed API or a vulnerable integration, it becomes part of a full attack chain.
The most typical scenarios include:
- Excessive or poorly segmented access rights.
- Compromise of a single account followed by lateral movement.
- Insecure integrations between services or via CI/CD.
- Use of external data without proper validation and control.
Such attacks are rarely stopped by automated security tools, because they appear as legitimate activity. Their consequences include data breaches, service disruption, direct financial losses, and a serious blow to reputation.
Why standard approaches do not always work
Role configuration, monitoring, logging, and regular scanning are a necessary foundation. However, all these measures share a common limitation: they analyze infrastructure in a fragmented way.
Automated tools answer the question “is an individual component configured correctly,” but they do not show what happens if an attacker combines several weak points into a single scenario.
This is where the gap between formal security and real system resilience appears. It cannot be closed with checklists or certifications – it requires modeling real attacks.
What is cloud infrastructure pentesting
Cloud infrastructure pentesting is a controlled simulation of attacks (attacker actions) aimed at achieving a specific outcome: gaining access to data, compromising services, or escalating privileges.
Unlike classical penetration testing, in the cloud the focus shifts from individual vulnerabilities to scenarios. Critical issues arise not within a single service, but at the intersection of several – which is why pentesting looks at the system “from the end,” from the perspective of potential impact.
Key indicators that a cloud pentest is needed right now
Cloud penetration testing is a response to change, not a scheduled formality. Most often, it becomes critically necessary at the following moments:
- Migration to the cloud or significant scaling of infrastructure.
- Introduction of new services, APIs, or external integrations.
- Changes in access roles, teams, or operational processes.
- Preparation for an audit, certification, or due diligence.
- Emergence of suspicious events or incidents without an obvious breach.
In each of these cases, the attack surface changes, and previous assumptions about security become outdated.
Who should conduct a cloud pentest
Internal teams know the infrastructure well, but this very familiarity often creates blind spots. That is why it is worth engaging external cybersecurity specialists – they bring an independent perspective, experience across different cloud environments and real-world attacks, as well as proven methodologies.
An example of such an outsourced team is the certified pentesters at Datami, which has over 9 years of practical experience in assessing the cybersecurity of organizations in more than 30 countries worldwide and has conducted over 400 pentests. This level of expertise makes it possible to assess not formal compliance with requirements, but the real ability of cloud infrastructure to withstand attacks.
Real cloud cybersecurity: What determines the outcome
In the cloud, security is never an inherent property of the platform itself. It is shaped by configurations, processes, and timely assessments. Regular and properly conducted cloud penetration testing services make it possible to identify risks before they turn into incidents and to maintain control over data, services, and business reputation.
