Cloud Environment Penetration Testing

We test the security of cloud environments across Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) by simulating real-world cyberattacks. We assess identity and access configurations, permissions, cloud services, storage, and network communication to identify vulnerabilities that could lead to cloud infrastructure compromise or sensitive data exposure.

Why Test Cloud Environments?

Cloud platforms provide organizations with flexibility, scalability, and the ability to deploy new services quickly. At the same time, they introduce new security risks that often result not from vulnerabilities in the cloud provider itself, but from misconfigured environments, identities, or access permissions. Cloud penetration testing simulates real-world attack scenarios and determines whether attackers could exploit misconfigured IAM policies, publicly accessible storage, cloud services, containers, or other infrastructure components. Our ethical hackers combine automated tools with manual testing to verify the real-world impact of every identified vulnerability. Regular cloud penetration testing helps organizations protect sensitive data, operate cloud services securely, and support compliance with standards and regulations such as NIS2, DORA, ISO 27001, and PCI DSS.

Protection of Sensitive Data

We assess the security of cloud storage, databases, backups, and other services that process sensitive data.

Prevention of Cloud Infrastructure Compromise

We identify vulnerabilities that could allow attackers to gain unauthorized access to cloud services or take control of the environment.

Support for Compliance with Security Standards

Penetration testing results support compliance with NIS2, DORA, ISO 27001, PCI DSS, and other security standards and regulatory requirements.

Stronger Cloud Security

Regular testing helps identify weaknesses before attackers can exploit them and improves the overall security and resilience of cloud environments.

What We Test

Request a Penetration Test

Identity and Access Management (IAM)

We assess the configuration of users, roles, permissions, service accounts, and access policies within cloud environments.

Cloud Storage

We test the security of object storage, databases, backups, and other services that may contain sensitive data.

Network Communication

We assess the configuration of virtual networks, firewalls, security groups, VPNs, and other network security controls.

Containers and Kubernetes

We test the security of container platforms, Kubernetes clusters, container image repositories, and container orchestration.

Serverless Services

We assess the security of cloud functions, their permissions, communication with other services, and potential attack paths.

Cloud Services and APIs

We assess the security of cloud services, APIs, and communication between them, including authentication and authorization.

What Cloud Penetration Testing Can Reveal

Cloud penetration testing goes beyond identifying individual configuration errors. It also assesses how multiple weaknesses can be combined to gain unauthorized access to cloud services, sensitive data, or the entire cloud infrastructure. Common findings include:

Excessive permissions assigned to users, roles, or service accounts can allow attackers to access sensitive cloud resources or escalate their privileges.

We assess whether cloud storage, databases, or backups are exposed to unauthorized users due to misconfiguration.

We identify misconfigured firewalls, security groups, VPNs, and network segments that could expose internal cloud services to attackers.

We test whether misconfigured identities, roles, or cloud services can be exploited to gain elevated privileges within the environment.

We test the security of containers and Kubernetes environments, including potential container escapes, privilege escalation, and unauthorized access to clusters.

We assess the authentication, authorization, and configuration of cloud APIs and identify potential paths to unauthorized access to functions or data.

We identify situations where sensitive data could be exposed through misconfigured services, storage, databases, or access permissions.

We assess whether passwords, access tokens, API keys, or other secrets are stored insecurely or accessible to unauthorized users.

Web Applications

We test web applications against attacks such as SQL Injection, Cross-Site Scripting (XSS), authentication flaws, and privilege escalation. Our web application penetration testing follows the OWASP Web Security Testing Guide and OWASP Top 10, with every finding manually verified.

Mobile Applications

Mobile application penetration testing for Android and iOS assesses the security of sensitive data, APIs, server communication, local storage, and the application's resilience against reverse engineering, rooting, jailbreaking, and other attack techniques.

AI and LLM Systems

We test the security of AI applications, chatbots, AI agents, and RAG systems. AI penetration testing assesses resilience against prompt injection, jailbreak attacks, sensitive data leakage, model manipulation, and abuse of external tools based on the OWASP Top 10 for LLM Applications.

Learn about AI & LLMs

Network Infrastructure and Internal Systems

We simulate attacks against internal and external infrastructure, including firewalls, VPNs, Active Directory, servers, and databases. Network penetration testing assesses network configuration, segmentation, privilege escalation, and an attacker's ability to move laterally across the environment.

APIs and Microservices

API and microservices penetration testing assesses the security of REST, GraphQL, and other APIs, including communication between microservices. We test OAuth, JWT, API gateways, authorization, input validation, and API resilience based on the OWASP API Security Top 10.
