Your web application can expose customer data, business functionality and internal systems through the same interface.
Security testing therefore needs to examine how authentication, authorisation, application workflows, APIs and business logic interact. NuageSEC combines manual security testing with automated assessment to identify and validate web application vulnerabilities.
NuageSEC's current web application security service covers OWASP Top 10-aligned testing, authentication, authorisation, injection, business logic, APIs and configuration.
Login mechanisms and authentication controls.
Whether users can access resources and functions outside their permissions.
Session security and authenticated access controls.
Application handling of user-controlled input.
Relevant SQL, command, XML and related injection risks.
Workflows that may be manipulated despite technically valid requests.
Security controls connecting the web application to APIs and services.
Relevant application security configuration and headers.

The most important weaknesses are not always exposed by automated signatures. For example, a scanner may recognise an endpoint — a skilled tester must determine:
Whether the endpoint should be accessible
Whether the authenticated user owns the requested object
Whether the user's role permits the function
Whether the workflow can be abused
Whether multiple legitimate operations can be chained
Whether an API returns information that the interface does not show
NuageSEC explicitly positions manual testing alongside automated assessment for web application security.
The ICO's current security guidance says organisations should implement appropriate technical and organisational measures and regularly test security effectiveness according to risk. It specifically references common web vulnerabilities, vulnerability scanning and penetration testing.
For a UK organisation processing personal data, application security testing can form part of a broader risk-management and security programme. It should not be presented as automatic UK GDPR compliance.
UK SaaS platforms may have the following components, which should be tested according to how the application actually works:
Multi-tenant access models
Customer administration
Payment workflows
Public APIs
Third-party integrations
Cloud deployments
Internal administrative functions
NuageSEC's June 2026 New Zealand e-commerce case study describes a web application handling authentication, workflows and sensitive business data. The engagement examined risks involving unauthorised data access, injection, application-logic manipulation and authentication/authorisation bypass.
This is presented as New Zealand customer evidence, not UK customer evidence.

A fixed annual assessment may become less representative as an application changes. NuageSEC's current PTaaS guidance supports recurring or on-demand security testing and identifies releases, new APIs, authentication changes, integrations, cloud migrations and business-workflow changes as events that can alter an application's attack surface.
Recurring testing can be quarterly, semi-annual or monthly depending on risk and operational requirements.
Direct answers to questions UK engineering and security leaders ask about web application security testing.
It is an authorised security assessment of a web application's technical and business-logic controls.
Yes.
NuageSEC's current web application service states OWASP Top 10 alignment.
Yes. Manual testing is combined with automated assessment.
Yes, where they are within the agreed scope.
Yes, where retesting is included.
It can contribute technical evidence to a broader security programme, but it does not itself establish UK GDPR compliance.
