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.
