Web Application Penetration Testing

Arcanum's Web Application Penetration Testing service stands as one of our premier offerings, delivering world-class security assessments designed to identify and mitigate vulnerabilities before they can be exploited. We safeguard every layer of your modern web estate, from classic LAMP stacks to today's cloud-native, JavaScript-heavy applications.

The Arcanum Difference

Elite Expertise & A Battle-Tested Approach

We bring over a decade of real-world offensive security experience managing advanced red team engagements, penetration tests, and bug bounty programs for Fortune 500 companies. We understand that the perimeter is where breaches often begin.

Decades of Fortune 500 Experience

Our service is built on over 20 years of specialized experience, led by Jason Haddix. Jason has personally tested web application technologies for the vast majority of Fortune 500 companies, combining rigorous structured assessments with real-world bug bounty hunting.

Industry-Leading, Recognized Methodology

Jason's methodology is highly regarded and sought-after across the cybersecurity industry. Engineers from premier, world-class consultancies globally attend Arcanum's specialized training courses (like the renowned "Bug Hunter's Methodology") to learn the very techniques we apply to your applications.

Bug Bounty DNA

Our testers cut their teeth on live-fire, high-stakes bug bounty programs where only the fastest, most creative, and persistent researchers succeed. We think like real-world adversaries, not just checklist auditors, finding critical breaches others miss.

A Modern Methodology
Beyond the OWASP Top 10

Web application security has transformed significantly. While critical server-side vulnerabilities (like SQLi, SSTI, CMDI, IDOR, etc) still pose immediate threats, they are often obscured, hidden behind blind spots, or require complex exploit chains. Furthermore, today's environment frequently presents sophisticated challenges:

  • Intricate client-side vulnerabilities (DOM XSS, prototype pollution, JS Gadgets).
  • Sophisticated misconfigurations demanding deep framework knowledge.
  • Emerging flaws in modern architectures (SPAs, GraphQL, service-workers, micro-frontends).

Content Discovery 2.0

A cornerstone taught in our methodology course, employing techniques often overlooked:

  • Historical artifact mining and discovery.
  • Deep JavaScript analysis and property graphing.
  • 403/404 error page and access control misconfiguration testing/pivots.
  • Intelligent, auth-gated spidering and forced Browse strategies.
  • Parameter discovery and manipulation.

Server-Side & Infrastructure Hardening

Identifying classic injection classes and misconfigurations in containers, serverless runtimes, edge gateways, and API integrations.

Specialist Bench On Demand

Need expertise in niche tech like WebAssembly, Shopify Liquid, GraphQL federation, ServiceNow, Salesforce Apex, or IoT Hybrid testing? We leverage our unique, vetted network to bring in specialized expertise unavailable through traditional consultancies.

Client-Side Analysis

Rigorous testing of modern client logic:

  • DOM-based XSS & CSP bypasses.
  • Prototype pollution & supply-chain injections (e.g., insecure third-party scripts).
  • Framework-specific attack surfaces (Next.js, Angular, React, Vue, etc.).

‍

Hybrid Fuzzing & Payload Engineering

Unlike many consultancies, we extensively utilize:

  • Payload-based and fault-injection fuzzing tailored to your application.
  • Target-aware fault injection for APIs, web-sockets, and cloud functions.
  • Differential analysis to surface race conditions, desyncs, and logic vulnerabilities.
