Web Application Penetration Testing

Find real vulnerabilities in your web applications before attackers do

NeedSec performs manual, in-depth penetration testing on modern web applications. We test every layer — authentication, session handling, access control, injection points, business logic, and client-side security — to find the vulnerabilities automated scanners miss.

Manual-led testing

Every assessment is led by a qualified security engineer — human judgment, not just automated scanning.

Evidence-backed findings

Each vulnerability includes proof of concept, reproduction steps, and a business-impact risk rating.

Actionable fix guidance

Reports are structured for developers and decision makers so remediation can start immediately.

What We Test

Focused testing against realistic attack paths

NeedSec combines manual testing, structured methodology, and business-focused reporting to identify issues that matter — not just scanner noise.

01

Authentication bypass — weak passwords, MFA bypass, and account enumeration

02

Session management — fixation, hijacking, token predictability, and cookie security

03

Broken access control — IDOR, privilege escalation, and forced browsing

04

SQL, command, LDAP, and template injection vulnerabilities

05

Cross-site scripting — reflected, stored, and DOM-based XSS

06

Insecure file upload — extension bypass, path traversal, and SSRF

07

Business logic abuse — price manipulation, workflow bypass, and quantity tampering

08

Security misconfiguration — verbose errors, debug endpoints, and default credentials

09

OAuth and third-party authentication flow security review

10

CORS policy and cross-origin request handling issues

11

HTTP security headers, CSP, and cookie attribute review

12

Client-side storage — localStorage, sessionStorage, and sensitive data exposure
