Web Application
Penetration Testing
Identify exploitable vulnerabilities in modern web applications, APIs, authentication flows, and business logic before attackers abuse them.
Do you need a web application penetration test?
A quick self-check. If several of these sound like you, it is worth a short conversation.
You likely need this if
- You run a customer-facing web app, portal or SaaS that handles logins, payments or personal data
- You have shipped major features, a redesign or a framework change since your last test
- A customer, partner or insurer is asking for an independent penetration test report
- You are preparing for ISO 27001, SOC 2, NIS2 or a similar audit that expects evidence of testing
- You have never had a manual test, or rely only on an automated scanner
Not sure where you land? A short scoping call will tell you plainly, including if you do not need this yet.
Book a scoping callA controlled, adversary-simulated assessment of your web applications
SoCyber combines manual testing with dynamic analysis to validate real-world impact across authentication, authorization, session management, input validation, business logic, and API integrations.
Our methodology is aligned with the OWASP Web Security Testing Guide and OWASP Top 10 risk categories, then tailored to your application architecture, user roles, data flows, and regulatory obligations.
Confirm which vulnerabilities can be exploited, which user journeys are affected, and what business impact they create.
Test whether user roles, tokens, cookies, MFA, password reset flows, and tenant boundaries resist real attacker techniques.
Find vulnerabilities automated scanners miss, including workflow bypass, payment logic abuse, privilege escalation, account enumeration, and tenant isolation errors.
Give developers clear reproduction steps, impact, affected endpoints, and prioritized fixes that can be retested quickly.
Securing your web presence is more important than ever
Modern web applications sit directly between customers, partners, employees, and critical data. Attackers no longer need physical access or malware if they can abuse login flows, APIs, misconfigured cloud storage, or weak authorization logic through the browser.
Improper object-level authorization, role checks, or multi-tenant isolation can allow attackers to view or modify data outside their permissions.
Weak password reset flows, MFA bypasses, exposed tokens, and insecure cookies create direct paths to account takeover.
Logic flaws in checkout, booking, credit, coupon, onboarding, or approval workflows can cause fraud, revenue leakage, and reputational damage even when code appears technically secure.
Regulations and standards such as NIS2, DORA, PCI DSS, ISO 27001, and GDPR expect organizations to validate technical controls, not only document them.
Structured approach for exceptional results
Scope & Preparation
Define in-scope applications, environments, user roles, APIs, integrations, authentication methods, and testing constraints. Collect architecture diagrams, data flows, and documentation to protect availability.
Attack Surface Mapping & Threat Modeling
We map application entry points, roles, routes, API endpoints, data flows, trust boundaries, and exposed technologies before active testing begins.
Vulnerability Assessment & Manual Testing
We test authentication, authorization, input validation, session management, configuration, client-side logic, file handling, and API behavior using OWASP-aligned techniques.
Exploitation & Business Impact Validation
We safely exploit verified weaknesses to prove real impact, such as IDOR, privilege escalation, injection, account takeover paths, insecure direct object access, and workflow abuse.
Reporting & Remediation Guidance
We deliver an executive risk narrative plus developer-ready technical findings with evidence, reproduction steps, severity, affected assets, and prioritized fixes.
Clear engineering guidance mapped to each finding, including recommended code changes, configuration fixes, validation criteria, and retest priorities.

Real-world business scenarios
Preventing Account Takeover
The Problem: Weak MFA enforcement, password reset logic, or exposed session tokens allow attackers to take over customer or employee accounts.
The Outcome: We validate login, recovery, session, and authorization controls so your team can close account takeover paths before they affect users.
Stopping Authorization & IDOR Data Exposure
The Problem: Users can directly access records, invoices, files, or tenant data by changing object IDs, URLs, or API parameters.
The Outcome: We test role boundaries, object-level authorization, and multi-tenant isolation to prove whether sensitive data can be accessed outside intended permissions.
Finding Business Logic Abuse Before Fraud
The Problem: Attackers exploit workflows such as discounts, payments, approvals, onboarding, or booking logic without triggering traditional vulnerability scanners.
The Outcome: We model real user journeys and abuse cases to uncover logic flaws that can cause revenue loss, fraud, or process manipulation.
Tangible deliverables & metrics
Executive Management Report
A high-level quantification of business risk, compliance alignment analysis, and a prioritized strategic investment roadmap for board-level review.
Technical Findings
Deep-dive evidence including affected URLs/endpoints, user roles, request/response samples, proof-of-concept payloads, and standardized severity scoring (CVSS/EPSS).
Number of verified vulnerabilities by severity, affected endpoints, remediation status, time-to-remediation, recurrence of issue patterns, and retest pass rate.
Close web application attack paths
Turn exploitable web application risks into prioritized fixes before your next release, audit, or security incident.
Sector context & industry relevance
Healthcare
The Problem: Patient portals, scheduling tools, telemedicine platforms, and admin dashboards handle sensitive health and personal data across many integrations.
The Outcome: We validate access control, session security, file handling, and data exposure paths to protect patient data and operational continuity.
Finance & Fintech
The Problem: Banking, fintech, payments, and customer portals are exposed to account takeover, transaction manipulation, API abuse, and tenant data leakage.
The Outcome: We test authentication, authorization, transaction logic, API security, and evidence trails to support DORA, PCI DSS, ISO 27001, and audit readiness.
Critical Infrastructure & Energy
The Problem: Supplier portals, field-service apps, dashboards, and OT-adjacent interfaces can become a bridge between external users and operational systems.
The Outcome: We validate segmentation, role boundaries, privileged workflows, and integration security so web apps cannot be used as a pivot into critical environments.
Regulatory standards alignment
Our web application penetration testing services are aligned with current application security frameworks and EU regulatory expectations, producing evidence that security controls have been independently validated.
-
DORA (Digital Operational Resilience Act): Supports regular ICT risk testing, scenario-based resilience validation, and evidence for financial entities and ICT third-party providers.
-
NIS2 Directive: Demonstrates active vulnerability management, secure development, incident prevention, and risk-based technical controls for essential and important entities.
-
PCI DSS / GDPR / ISO 27001: Validates protections for cardholder data, personal data, access control, logging, vulnerability management, and secure configuration.
DORA requires financial entities and critical ICT providers to maintain resilient systems and test ICT controls. Customer portals, back-office applications, and APIs are common attack paths for account takeover, transaction fraud, and data leakage.
-
Authentication & MFA Testing: Validating login, recovery, step-up authentication, and session controls against account takeover techniques.
-
Transaction & Workflow Abuse Testing: Testing payment, approval, onboarding, and customer-service flows for logic manipulation.
-
API and Third-Party Integration Review: Assessing partner APIs, token handling, webhooks, rate limits, and data exchange security.
-
Evidence for Remediation & Retesting: Producing traceable findings, severity ratings, and closure evidence for audit and risk committees.
Under the NIS2 Directive, essential and important entities must implement risk management measures that reduce the likelihood and impact of cyber incidents. Web applications used by customers, suppliers, and internal teams often store personal, operational, and commercial data that attackers can exploit through weak access control or insecure integrations.
-
Access Control & Privilege Review: Testing user roles, object-level permissions, tenant isolation, and privilege escalation paths.
-
Secure Configuration & Exposure Testing: Reviewing headers, error handling, file exposure, debug routes, and insecure deployment patterns.
-
Remediation Evidence: Providing prioritized findings and retest validation to support vulnerability management records.
Organizations processing payments or personal data must show effective controls around secure access, data minimization, encryption, logging, and vulnerability management. Web application penetration testing provides practical evidence that these controls work under realistic attack conditions.
-
Cardholder & Personal Data Exposure: Testing whether sensitive records, invoices, exports, logs, or files can be accessed without authorization.
-
Input Validation & Injection Testing: Validating protection against SQL injection, NoSQL injection, command injection, XSS, SSRF, and unsafe deserialization.
-
Logging & Error Handling Review: Checking whether sensitive information leaks through errors, debug output, browser caches, or insecure logs.
