OWASP 2025 ALIGNED
Web Application Security
Assessment
Expert-led penetration testing combining automation with manual tradecraft — aligned to the OWASP Top 10:2025 and ASVS across every layer of your web application, delivered through NST Assure.

Application penetration testing goes beyond scanners. We combine algorithmic automation with deep manual expertise across grey-box and black-box engagement modes — covering authentication, injection, server-side exploitation, client-side controls, business logic, and supply-chain integrity — delivered through NST Assure, our PTaaS platform for collaborative remediation and continuous assurance.
01
IDENTITY, ACCESS & SESSION CONTROLS
Authentication, Authorisation & Session Management
Comprehensive assessment of identity and access controls across grey-box and black-box modes — targeting the mechanisms that gate every privileged action in your application.
•
Authentication mechanisms — credential policies, brute-force resilience, MFA implementation, and SSO/OAuth flow validation
•
Authorisation enforcement — privilege escalation, IDOR, role-boundary bypass, and horizontal/vertical access control gaps
•
Session management — token generation entropy, fixation, replay, timeout enforcement, and concurrent-session handling
•
Password & credential security — storage hashing, reset-flow abuse, enumeration vectors, and account lockout logic
•
Identity federation — SAML assertion flaws, JWT manipulation, OAuth redirect abuse, and token-exchange weaknesses

INJECTION, SSRF, FILE UPLOAD & DESERIALISATION
Injection & Server-Side Security
Deep manual testing of all server-side input-processing paths — from classic injection vectors to modern server-side exploitation techniques in both grey-box and black-box modes.
•
SQL & NoSQL injection — blind, time-based, error-based, and second-order injection across all database engines
•
Server-side request forgery — internal service enumeration, cloud metadata access, and protocol-smuggling chains
•
Template & expression injection — SSTI in Jinja2, Twig, Thymeleaf, and server-side expression-language abuse
•
File upload & path traversal — unrestricted upload, extension bypass, double-extension, and directory traversal exploitation
•
Deserialisation & command injection — insecure object unmarshalling, OS command chaining, and XXE in parsers

DOM, CSP, CORS & TRANSPORT SECURITY
Client-Side & Browser Security
Validates client-side controls, browser security policies, and front-end attack surface — targeting vulnerabilities that server-side testing alone cannot uncover.
•
DOM-based attacks — DOM XSS, prototype pollution, client-side template injection, and open redirects
•
Security header validation — CSP bypass, missing HSTS, X-Frame-Options, and Permissions-Policy enforcement
•
CORS misconfiguration — overly permissive origins, credentialed wildcard access, and pre-flight bypass
•
Clickjacking & UI redress — frame injection, tabnabbing, and drag-and-drop based attacks
•
WebSocket & real-time — origin validation, message injection, and cross-site WebSocket hijacking

WORKFLOW, STATE-MACHINE & EDGE-CASE ANALYSIS
Business Logic & Transaction Integrity
Expert-driven testing of application workflows and business rules that automated scanners cannot detect — uncovering flaws unique to your application's logic and state management.
•
Workflow manipulation — step-skipping, parameter tampering, and multi-step process abuse in checkout, approval, and registration flows
•
Race conditions — time-of-check/time-of-use flaws, concurrent-request abuse, and double-spend or double-submit vulnerabilities
•
Payment & transaction logic — price manipulation, discount stacking, currency rounding, and gift-card or voucher bypass
•
Rate limiting & anti-automation — CAPTCHA bypass, throttle evasion, and resource-exhaustion through uncapped operations
•
Exceptional condition handling — fail-open behaviour, error-state leakage, and logic flaws under malformed or edge-case input

HARDENING, CRYPTO & DEPENDENCY INTEGRITY
Configuration, Cryptography & Supply Chain
Validates infrastructure hardening, cryptographic implementation, and software supply-chain integrity — reflecting the highest-climbing categories in the OWASP Top 10:2025.
•
Security misconfiguration — default credentials, exposed admin interfaces, verbose errors, directory listing, and missing server hardening
•
Cryptographic failures — weak algorithms, improper key management, insecure transport, certificate misuse, and insufficient entropy
•
Supply-chain failures — malicious packages, compromised maintainers, tampered builds, and dependency-confusion attacks
•
Software integrity — CI/CD pipeline verification, unsigned artefacts, insecure deserialisation, and integrity-check bypass
•
Insecure design — threat modelling, missing security controls, architectural weaknesses, and secure-by-design validation
