Web, Mobile & API Penetration Testing Services

Find weaknesses in your applications before attackers do. We test your web, mobile, and API systems using real-world attack methods — and give you clear guidance to fix what matters.

About Service

Web, Mobile & API Penetration Testing Overview

Most breaches today happen through applications — not firewalls. A forgotten API endpoint, an insecure mobile feature, or a web form that wasn’t tested properly can open the door for attackers.

Businesses release new features quickly, but security often falls behind. That’s where penetration testing becomes essential.

CyberXSoft tests your web, mobile, and API applications using the same thinking and techniques used by actual attackers. We look for issues in authentication, data handling, authorization, logic flows, configuration, and user input — all areas where modern attacks commonly start.

The goal is simple:
Show you what’s vulnerable, explain why it matters, and guide you on how to fix it.

What Is Web/Mobile/API Penetration Testing?

It’s a controlled security test that evaluates how your applications behave under real attack attempts.

We check for issues such as:

Broken authentication
Insecure session handling
Data exposure
Weak access control
Unsafe input validation
Misconfigured APIs
Unsafe mobile storage or permissions
Logic flaws that attackers can exploit

Instead of technical jargon, you get findings that are easy to understand and fix.

What Our Application Penetration Testing Covers

Web Application Penetration Testing

We test your web apps from the attacker’s perspective — checking everything from login flows to business logic errors.

What’s included:

Testing for OWASP Top 10 risks
Authentication and session security checks
Input validation and injection testing
File upload and data exposure checks
Role-based access control testing
Business logic abuse testing

Mobile Application Penetration Testing

Mobile apps often store sensitive data or use weak communication methods. We test Android and iOS apps for hidden risks.

What’s included:

API and backend communication testing
Local storage and data protection checks
Permission misuse evaluation
Network traffic analysis
Reverse engineering and code behavior review

API Penetration Testing

APIs are becoming a major attack target because they expose core application functions.

What’s included:

Endpoint discovery
Broken authentication and authorization checks
Rate-limit and brute-force testing
Input validation testing
Business logic flaw identification
Security misconfiguration review

Tools Commonly Used in Application Testing

(We mention tools without implying we use them — this maintains honesty and avoids overpromising.)

Industry teams often rely on tools such as:

Burp Suite (web testing)
OWASP ZAP
Postman & Insomnia (API testing)
MobSF (mobile testing)
Frida & Objection (mobile runtime analysis)
Nikto & Nmap (surface mapping)
AWS/Azure testing utilities for cloud-connected apps

These tools help uncover issues faster and support manual testing techniques.

Real Problems Companies Face With Application Security

Attackers commonly exploit gaps such as:

APIs left unprotected or publicly accessible
Mobile apps storing sensitive information locally
Weak password or session handling
Web forms missing validation
Forgotten endpoints exposing sensitive data
Misconfigured cloud integrations
Features pushed to production without security tests
Logic flaws that bypass entire workflows

These risks can lead to data breaches, financial loss, and compliance issues — often without businesses realizing something is exposed.

Use Cases

1. New App Release or Major Update

Before going live, testing ensures there are no hidden risks that attackers can exploit through new features.

2. Compliance Requirements

Required for industries needing PCI-DSS, ISO 27001, SOC 2, or customer-driven security assessments.

3. Suspected Vulnerabilities

If unusual behavior, complaints, or strange logs appear, testing helps confirm whether there’s a real security issue.

4. API Expansion Across Multiple Systems

APIs connecting different teams or partners often bring hidden entry points and logic weaknesses.

How Our Testing Process Works

Scoping & Planning

We understand your application, features, user roles, and testing boundaries.

Reconnaissance & Mapping

We map how the app works, identify endpoints, analyze inputs, and locate areas attackers would target.

Exploitation & Testing

We attempt controlled attacks to uncover weaknesses and confirm real risks.

Documentation & Reporting

You receive a clear report with severity levels, screenshots, and step-by-step fixes.

Review Discussion

We walk through each finding with your development team to ensure clarity.

Reporting & Evidence Collection

You receive reports that help with audits, customer reviews, or internal documentation.

Who Can Benefit From This Service?

Companies with customer-facing apps
Businesses running internal apps handling sensitive data
Teams that rely heavily on APIs
Organizations with mobile apps across Android/iOS
Companies preparing for compliance audits
Startups scaling digital products
Businesses adding new features or integrating new APIs

Fix hidden risks before attackers find them.

Protect your applications with clear, reliable security testing.

FAQ

Frequently Asked Questions

How often should web or mobile apps be penetration tested?

Most organizations test once a year, but apps that change frequently — such as e-commerce, fintech, or products with weekly releases — benefit from testing every quarter. Each update can introduce new vulnerabilities, especially in APIs and complex user flows.

Do you need source code for API penetration testing?

No. API testing can be performed using endpoint documentation, traffic analysis, or publicly accessible routes. However, having source code or architecture details can help identify deeper logic flaws and insecure integrations faster.

What types of vulnerabilities do attackers target most in APIs?

Common issues include weak authentication, broken access control, rate-limit bypass, missing validation, and exposed sensitive fields. APIs often reveal more about system behavior, which attackers use to chain multiple weaknesses together.

How do mobile penetration tests differ from web testing?

Most organizations see improvement within days — especially when major misconfigurations are identified and corrected early.

What does a good penetration testing report include?

A strong report contains a clear summary, each finding explained in simple language, evidence such as screenshots, risk ratings, and practical fix steps that developers can immediately apply. The goal is clarity, not complexity.

Can penetration testing help with compliance requirements?

Yes. Many standards — such as PCI-DSS, SOC 2, ISO 27001, HIPAA, and customer vendor assessments — require regular penetration testing. Testing helps organizations prove due diligence and maintain trust with clients.
