Web Application Penetration Testing Services

Manual, senior-led testing for SaaS and fintech teams that need credible findings before a release, customer security review, or an agreed compliance milestone.

  • Authenticated testing across agreed roles and tenants.
  • Validated business-logic and application-security findings with reproduction steps.
  • Prioritized remediation guidance with optional retest.

Who this is for

  • SaaS and fintech teams responding to an enterprise customer's request for an independent test.
  • Product teams preparing a release or an agreed customer security review milestone.
  • Engineering leaders investigating authorization and tenant-isolation concerns.
  • Growing businesses that need reproducible findings rather than a scanner-only report.

What you receive

Agreed scope and authorization
Targets, environments, roles, test windows, exclusions, permitted techniques, escalation contacts and reporting are agreed before testing.
Authentication and sessions
Manual testing of authentication, session handling and access-control boundaries within the authorized application scope.
Role and tenant access control
Assess whether agreed users can access another role's functions or another tenant's data.
Workflow and data handling
Investigate workflow abuse, input handling, injection and sensitive data exposure in agreed application paths.
Evidence and remediation
An executive summary and technical findings with severity, evidence, reproduction steps and actionable fix guidance. Customer-facing use is agreed and appropriately redacted.
Optional remediation retest
A separately agreed retest can verify fixes to the identified findings. Retesting is optional, not automatically included.

Who you work with

ControlSolid delivers manual, senior-led application security testing, informed by prior application-security work at Amazon Web Services.

  • Testing focuses on application-specific behavior, not just automated scanner output.
  • Findings are written for engineering teams and leadership.

This engagement is web application penetration testing, not broader internal or external network testing, segmentation testing or official PCI validation. Share only a high-level scope and business need in the public form. Do not send credentials, API keys or sensitive system details.
