Your web application can be the entry point to customer accounts, business workflows, APIs and sensitive information.
NuageSEC provides web application security testing for organisations in Germany, combining manual analysis with automated assessment to identify and validate application vulnerabilities before attackers exploit them.
NuageSEC's current web application service describes OWASP Top 10-aligned testing, authentication, authorisation, injection, business logic, APIs and configuration.
Login mechanisms, multi-factor authentication, SSO integrations and credential handling under hostile manipulation.
Testing whether users can access resources, functions or data outside their explicitly granted permissions.
Sessions, bearer tokens, cookies, concurrent logons and session timeout handling across user states.
Assessing how applications validate, sanitize and handle user-controlled input across all fields and headers.
Evaluating applications for SQL injection, command injection, XML/XXE and template injection risks.
Validating whether legitimate workflows, order checkouts and approval steps can be abused to produce unintended results.
Testing the security boundaries, data leakage and authentication states between web interfaces and backing APIs.
Reviewing security headers, CORS policies, transport encryption, error handling and deployment configurations.
A scanner can identify a suspicious input. An expert manual penetration assessment asks the questions that matter to your business:
Can the user access another customer's object?
Can a user role be vertically escalated?
Can an administrative workflow be reached by standard users?
Can two valid actions be chained into an unintended result?
Can an API expose information that the user interface never displays?
NuageSEC's service explicitly positions expert manual testing alongside automated scanning to validate complex multi-step exploits.
German digital platforms combine portals, multi-tenant applications, payment pipelines and APIs. The assessment reflects how these components actually interact.
Public-facing portals, client extranets and self-service account management.
Shared database, siloed schema or tenant-isolated cloud architecture.
Internal tooling, back-office consoles and role-delegated management.
Checkout pipelines, subscription billing and third-party gateway integrations.
REST, GraphQL and microservices orchestrating critical data exchanges.
AWS, Azure and European cloud infrastructure hosting application workloads.
Webhooks, CRM connectors, analytics scripts and vendor dependencies.
Technical application security assessments provide verifiable evidence supporting governance and compliance obligations across Europe.
Article 32 GDPR requires appropriate security measures based on risk and specifically includes regular testing, assessment and evaluation of technical and organisational security measures.
Where personal data is processed through a web application, security testing provides useful technical evidence about vulnerabilities affecting confidentiality, integrity and availability.
Note: It does not replace the organisation's wider data-protection and governance programme.
For entities covered by the German NIS2/BSIG framework, security risk management includes security in the acquisition, development and maintenance of information systems together with vulnerability management.
§30 BSIG requires appropriate and effective technical measures proportionate to risk. Web application security testing contributes technical evidence to those activities where applications form part of the in-scope environment.
Assessments document how technical controls perform under deliberate exploitation.
For enterprise and manufacturing organisations, web applications often sit directly between employees, customers, suppliers, identity systems, cloud services and business-critical processes.
Testing should consider trust relationships and attack paths rather than just isolated application endpoints. Where applications interface with shop-floor systems, logistics or operational technology, testing scope must explicitly protect operational continuity.
B2B extranets, vendor portals and EDI interfaces.
Kerberos, Active Directory, Entra ID and corporate SSO federation.
Rigorous rules of engagement preventing downtime in production.
Continuous releases, new APIs, integrations, authentication redesigns and cloud migrations constantly alter an application's attack surface. Useful triggers include:
NuageSEC's current reporting model emphasises technical evidence, prioritisation, business impact and actionable developer remediation support.
Strategic overview of critical risks and business exposure tailored for German leadership and CISOs.
Granular findings with CVSS scores, affected URL endpoints, parameters and architectural context.
Concrete reproduction steps, raw HTTP payloads and exploitation transcripts proving real exploitability.
Risk scoring calibrated to your organisation's real operational exposure and business criticality.
Clear contextual explanation of what each technical finding means for operations and data integrity.
In-depth identification of underlying flaws in code, framework misconfiguration or design logic.
Actionable, developer-focused recommendations, code snippets and framework-specific patch guidance.
Independent validation testing confirming that reported vulnerabilities were resolved effectively.
NuageSEC transparently presents its published international case evidence as proof of technical depth across modern web application perimeters.
NuageSEC evaluated an e-commerce platform covering customer workflows, authentication, session management, input validation, access control, APIs and application configuration. The assessment included proof-of-concept exploitation, root-cause analysis, risk classification and developer remediation guidance.

Direct answers to common questions German organisations ask about web application security.
It is an authorised assessment of web application security controls, vulnerabilities and business logic.
Yes. NuageSEC combines manual testing with automated scanning to evaluate authentication, authorisation and business logic.
Yes. NuageSEC's current web application service aligns with the OWASP Top 10 framework.
Yes, where included in the authorised scope.
It can contribute technical evidence and identify vulnerabilities relevant to broader risk management, but it does not establish NIS2 compliance by itself.
No. It provides technical verification for a defined scope, supporting a broader data protection and security programme.
Yes, where retesting is included.
Validate authentication, authorisation, business logic, APIs and security configuration with evidence your engineering and security teams can act on.
