What we assess
Identity and sessions
Login, recovery, multi-factor controls, session lifecycle and account switching.
Access boundaries
Role and tenant separation, object ownership and privileged functions.
Input and data handling
Injection risks, uploads, server-side processing, output handling and sensitive data exposure.
Business workflows
Transactions, approval steps and state transitions, using agreed test accounts and data.
Who it is for
Engineering teams, SaaS founders and security owners preparing for a launch, enterprise review or material application change.
Before we start
Share the application URLs, approximate roles and workflows, available test environment and release timeline. Provide test accounts through an agreed secure channel after scoping, never in the enquiry form.
Methodology
From scope to verified fixes.
Map user journeys and trust boundaries, then test the same action across controlled accounts and roles. Use OWASP guidance as a starting point and extend coverage to application-specific behavior. Confirm impact with the least intrusive evidence permitted by the rules of engagement.
- Agree authorization, coverage, test limits and evidence handling.
- Discover and manually validate candidate weaknesses.
- Report confirmed findings, unverified observations and coverage limitations distinctly.
- Discuss remediation and retest the specified fixes within the agreed window.
Typical issues we look for
Examples of possible issues, not findings from R53SEC client engagements. Actual results depend on the system and scope.
- A user can access another tenant’s record because ownership is not checked on the server.
- A workflow accepts an action out of sequence and bypasses an intended approval.
- An upload path exposes sensitive content or interprets untrusted data unsafely.
What you receive
A coverage summary of agreed roles and workflows, reproducible findings with redacted request/response evidence, risk rationale and fixes tied to the affected application components.
The report includes an executive summary, finding identifiers, severity rationale, impact, evidence, remediation and coverage limitations. CVSS is included where appropriate with its version, vector and assumptions. Retest scope, timing and commercial terms are agreed before work begins.
Questions about Web Application VAPT
Does VAPT mean running an automated scanner?
Tools support discovery. Manual testing investigates authorization, workflows and exploitability, and distinguishes confirmed findings from unverified observations.
Can testing take place on a production application?
Only under an explicitly agreed scope, test window and safety limits. A representative test environment is preferable for activities that could affect data or availability.
Are APIs included?
Connected APIs are included only when named in scope. A dedicated API assessment may be useful where the API has its own roles, integrations or business logic.
