Find the vulnerabilities before someone else does.

Hands-on web application and network penetration testing. Real attack paths, reproducible findings, and reports your engineers can act on.

Services

What we test

Web Application Penetration Testing

Manual testing of your application's authentication, authorization, business logic, and input handling. We go beyond scanner output to find the flaws that matter.

  • OWASP Top 10 and ASVS-aligned coverage
  • Access control and IDOR testing
  • Session, auth, and SSO flows
  • Business logic abuse

API Security Testing

REST and GraphQL APIs tested the way attackers use them, including the endpoints your front end doesn't show.

  • OWASP API Security Top 10
  • Object- and function-level authorization
  • Mass assignment and data exposure
  • Rate limiting and abuse cases

External Network Penetration Testing

Your internet-facing footprint from an attacker's point of view: exposed services, misconfigurations, and paths into your environment.

  • Attack surface discovery
  • Service and configuration review
  • Credential and exposure testing
  • Exploitation to prove impact

Internal Network Penetration Testing

Shows what an attacker who is already inside could reach, starting from an assumed-breach position on your network.

  • Active Directory attack paths
  • Lateral movement and privilege escalation
  • Segmentation testing
  • Sensitive data exposure

Approach

How an engagement works

  1. Scope

    We agree on targets, rules of engagement, testing windows, and contacts before any testing starts.

  2. Test

    Manual, methodology-driven testing, with tools supporting the work. We contact you right away if we find something critical.

  3. Report

    An executive summary for leadership. Reproducible technical findings with risk ratings and remediation guidance for engineers.

  4. Readout

    A walkthrough call to go over the findings and answer your team's questions.

  5. Retest

    After you fix the issues, we verify the fixes and issue an updated report.

About

Small firm, senior hands

Entropyth LLC was founded in 2025 by a security engineer who specializes in web application vulnerabilities. The founder came up through network engineering and system administration, so we understand how real environments are built and how they break.

When you hire Entropyth, the person who scopes your engagement is the person who tests it. You won't be passed off to a junior team or handed a rebranded scanner report.
