Security & Penetration Testing

Find the Vulnerabilities Before Hackers Do

Every app has security holes. The question is whether you find them first or attackers do. We run OWASP-based security audits and penetration tests that expose the real risks in your web app, API, and mobile app — before they become headlines.

What We Test For

The OWASP Top 10 and beyond — the vulnerabilities that actually get exploited.

SQL Injection

Every input field, API parameter, and query string tested for SQL injection vulnerabilities that could expose your entire database.

Cross-Site Scripting (XSS)

Stored, reflected, and DOM-based XSS vulnerabilities that let attackers run malicious scripts in your users' browsers.

Broken Authentication

Session management flaws, weak password policies, missing MFA enforcement, and authentication bypass techniques.

IDOR & Broken Access Control

Can user A access user B's data by changing an ID in the URL? Insecure Direct Object References are the most common API vulnerability.

Sensitive Data Exposure

API keys in client-side code, unencrypted sensitive data, overly verbose error messages, and insecure data transmission.

Security Misconfigurations

Default credentials, open admin panels, verbose error messages, missing security headers, and CORS misconfigurations.

Industries That Can't Afford Breaches

Security testing is non-negotiable in these verticals.

Fintech & Payments

PCI
Compliance Ready

Financial data, payment flows, and transaction APIs are prime targets. A breach here isn't just embarrassing — it's regulatory.

Healthcare Apps

HIPAA
Adjacent Testing

Patient data, medical records, and health information require the highest security standards. We test to HIPAA-adjacent requirements.

SaaS Products

100%
Tenant Isolation

Multi-tenant SaaS apps must ensure tenant isolation. One customer should never be able to access another's data.

AI-Generated Apps

Critical
Issues Found

Lovable, Cursor, and Bolt apps have never had a security engineer review the code. This is where we find the most critical issues.

Common Challenges

Problems We Help Buyers Solve

QA gaps show up as regressions, store rejections, and security findings — usually right before launch.

No regression suite

Manual smoke tests can't keep pace with weekly releases.

AI-generated untested code

Lovable and Cursor prototypes reach staging without auth or edge-case coverage.

Device fragmentation

Mobile flows break on OS versions QA didn't cover.

Late QA

Testing in launch week makes fixes expensive and stressful.

Buyer Guide & Decision Framework

Security & Penetration Testing: Scope, Pricing & Buyer Guide

At-a-glance scope, pricing tiers, delivery timelines, engineering tradeoffs, and decision criteria for technical founders and product leaders.

What is Security & Penetration Testing?

Software QA and technical audit services cover manual and automated testing, performance and security checks, and senior engineer code review — especially for AI-generated or inherited codebases before production launch.

How much does Security & Penetration Testing cost?

Pricing depends on scope, integrations, and timeline. GreeLogix provides transparent fixed-milestone quotes after discovery, with flexible models for one-off audits, sprint retainers, or dedicated engineers.

Need to model sprint hours and coverage? Use our QA estimation calculator.

Key Cost Factors

  • ·App complexity and number of platforms (web, iOS, Android)
  • ·Automation scope vs manual-only
  • ·Security or penetration testing depth
  • ·Whether you need embedded QA or per-release engagement

How long does delivery take?

Smoke audit: 1 week. Full regression cycle: ongoing per sprint. Deep code audit: 5–7 business days. Phases: Strategy (Week 1); Execution (Per sprint); Automation (Parallel).

Delivery Phases

  1. 1.Test strategy: risk map, environments, and release criteria
  2. 2.Execution: test cases, bug reports with repro steps, regression suites
  3. 3.Automation wired into CI where ROI is clear
  4. 4.Release sign-off report with go/no-go recommendation

Who is it for?

  • ·Teams shipping Lovable, Cursor, or Bolt prototypes to real users
  • ·Founders facing investor technical diligence
  • ·Products with regressions every sprint and no test automation
  • ·Mobile apps needing device-matrix testing before store release

When NOT to use this service

  • ·Static marketing site with no auth or payments
  • ·You cannot provide staging access or test accounts
  • ·You expect QA to define product requirements

Pros / Benefits

  • +Catch permission and payment bugs before customers do
  • +Documented release checklist for repeatable shipping
  • +Investor-ready technical risk summary

Risks to Plan For

  • −QA without product context files shallow tickets
  • −Testing only happy paths misses edge cases in billing and roles
  • −Delaying QA until launch week maximizes fix cost

How Does Security & Penetration Testing Compare to Alternatives?

Frequently Asked Questions

Answers to the buyer questions we hear most before a project starts.

What is penetration testing?

Penetration testing (pen testing) is a simulated cyberattack on your application to find security vulnerabilities before real attackers do. Our engineers attempt to exploit weaknesses in your app using the same techniques malicious hackers use — then document every finding with fix recommendations.

Why is security testing especially important for AI-generated apps?

AI tools like Lovable, Cursor, and Bolt generate functional code quickly, but they don't apply security hardening. Common issues include missing input validation, insecure direct object references, exposed API keys in client-side code, and broken authentication flows. No human reviewed the security implications of the generated code.

What does the security report include?

You receive an executive summary (non-technical), a detailed technical findings section with CVSS severity scores, proof-of-concept for each vulnerability, and specific fix recommendations. We also offer a retest after fixes are applied to confirm vulnerabilities are resolved.

Our Process

01

Scope Definition

We define the attack surface — which URLs, APIs, and features are in scope — and agree on testing boundaries.

02

Reconnaissance & Mapping

We map your application's attack surface, identify technologies, and plan our testing approach.

03

Active Penetration Testing

Our engineers attempt to exploit every identified vulnerability using real attacker techniques.

04

Report & Retest

Detailed report with CVSS scores, proof-of-concept, and fix recommendations. Free retest after fixes applied.
