Approaching Launch
A new website, portal or software-as-a-service (SaaS) platform approaching release.
CYBERSECURITY TESTING
Web Application
Web Application
Security Testing & Analysis.
Find exploitable weaknesses before they reach your customers. We combine automated discovery with deep manual analysis because scanners alone rarely understand user roles, trust boundaries, or business logic abuse.

APPLICATION ASSURANCE
When is Testing Necessary?
Testing can be performed before release, after a significant change, as part of supplier assurance or as a recurring control. The exact depth depends on the application's sensitivity, complexity, user roles, integrations and exposure.
Major Releases & Updates
Major changes modifying authentication, payment processing, file handling, administration, or customer data flows.
Outdated Assessments
Applications that have not received independent manual penetration testing within the past year.
Compliance & Supplier Audits
Customer, investor, insurer, or procurement requests requiring independent security assurance.
Suspected Weakness & Incidents
Following a suspected vulnerability disclosure, threat change, or security incident involving your online services.
TESTING SCOPE
What We Test
We map the application, identify security controls, and safely validate weaknesses using agreed test accounts and data. The result is a prioritized remediation roadmap containing clear evidence and reproduction steps.
Attack Surface & Configuration
Authentication & Recovery
Authorisation & User Separation
Input Handling & Injection
Session & Token Security

ENGAGEMENT PROCESS
How the Engagement Works
Scope & Authorise
Agree target URLs, testing environments, user roles, exclusions, test windows, and rules of engagement.
Map the Application
Review documentation and safely enumerate functionality, API endpoints, technologies, and trust boundaries.
Test & Validate
Combine appropriate tooling with manual techniques to distinguish exploitable issues from false positives.
Assess Impact
Demonstrate realistic impact with the minimum action necessary and without retaining customer data.
Report & Brief
Provide a risk-rated technical report and a clear briefing for technical and business stakeholders.
Re-test Fixes
Verify agreed remediations and record which findings are resolved, partially resolved, or still present.

DELIVERY CAPABILITIES
Engagement Options
- Unauthenticated external testing - Assessment of public login pages and unauthenticated routes for external threats.
- Authenticated role-based testing - Multi-user role assessments to check vertical and horizontal authorization boundaries.
- Black, Grey, or White-box testing - Delivery tailored to your objective, from zero-knowledge tests to source-code reviews.
- Staging & Pre-release testing - Conducted inside QA environments to secure features before they enter production.
- Focused Delta testing - Concentrated testing of specific features, payments, or critical updates rather than the whole app.
PREREQUISITES
What We Need
- Authorized target URLs - Confirmed target scopes and explicit authorization/authority to conduct testing.
- Test Accounts - Working login credentials for each user role and administrative tier to be assessed.
- Architecture Context - Basic data-flow maps or API specification documentation if available.
- Rules & Constraints - Details on known exclusions, fragile logic, test schedules, and environment limits.
- Technical Contact - A designated, responsive contact available during active testing windows.
Important Scope and Safety Note
All testing is performed only against explicitly authorised targets and within agreed rules of engagement. Potentially disruptive techniques, denial-of-service activity, destructive actions and access to real personal data are excluded unless separately risk-assessed and expressly approved. A test provides point-in-time assurance; it cannot guarantee that an application is free from every vulnerability.
COMMON ASKED QUESTIONS
Frequently Asked Questions
Is this the same as an automated website scan?
No. Automated tools are useful for finding known missing patches, but they cannot assess multi-tenant separation, business logic abuse, workflow skipping, or multi-step form authentication. We manually validate all issues to ensure zero false positives.
Can you test a live production website?
Yes. We can test production applications safely by establishing clear rules of engagement, avoiding disruptive payloads, and scheduling tests during low-traffic windows. Testing in a staging/QA environment is preferred for fragile or write-heavy features.
Do you need the application's source code?
Not necessarily. In black-box testing, we operate with zero prior knowledge. In grey-box testing, we utilize test accounts and selected documentation. White-box testing can include full source code access to accelerate findings. The model is chosen during scoping.
Will you test our API endpoints too?
APIs that support the web application's user interface are tested as part of the core scope. If your APIs are externally consumed or have a large footprint, we recommend a dedicated API security assessment to test endpoints systematically.
Does passing a test mean the application is 100% secure?
No. A security assessment provides point-in-time assurance based on the targets and methods used. It is an essential control, but must be combined with secure software development lifecycles (SSDLC), monitoring, and continuous vulnerability management.
How often should we repeat web testing?
Common triggers are major code releases, changes to authentication mechanism, new cloud integrations, supplier audits, or standard annual/risk-based review cycles.
