Hawthorn Security

Identifying vulnerabilities before they become threats.

Services

We find it,
before they do

Hawthorn Security specialises in hands-on penetration testing and security auditing for web systems, mobile applications, server infrastructure, and the people who use them. We know the stacks you build on because we build on them too.

Web & PHP
Code Auditing

Deep-dive security audits of PHP applications, Laravel codebases, and web platforms. We go beyond automated scanning to manually review your source code for injection flaws, authentication bypasses, and business logic vulnerabilities.

Flutter & Mobile
App Auditing

Security assessments of Flutter, iOS, and Android applications. We test data storage, API communications, certificate pinning, reverse engineering resilience, and platform-specific attack vectors unique to mobile.

Server & Infra
Pen Testing

Internal and external penetration testing of your server infrastructure. Linux hardening reviews, cloud configuration audits, network segmentation testing, and privilege escalation assessments across your entire stack.

Corporate Social
Engineering

Targeted phishing campaigns, pretexting, vishing, and physical access testing tailored to your organisation. We expose the human vulnerabilities that no firewall can patch and help you build a security-aware culture.

About us

Approach and
philosophy

Hawthorn Security exists because we've spent over 16 years building the same systems we now break. Our background in PHP, Laravel, Flutter, and Linux infrastructure means we audit your code and servers with the mindset of someone who's shipped production software, not just scanned it.

We pair deep technical testing with corporate social engineering to give you a complete picture of your exposure. Every engagement is handled with discretion, delivered with clarity, and focused on actionable outcomes rather than padded reports.

Capabilities

What we
specialise in

PHP & Laravel Source Code Review

Manual line-by-line auditing of your PHP codebase. SQL injection, mass assignment, insecure deserialization, broken access control, and framework-specific misconfigurations in Laravel, Symfony, and vanilla PHP.

Flutter & Dart Security Analysis

Reverse engineering of Flutter binaries, Dart source review, API token leakage, insecure local storage, and platform channel security across both iOS and Android builds.

Linux & Cloud Infrastructure Auditing

SSH hardening, firewall rule review, container escape testing, privilege escalation chains, and cloud misconfigurations across AWS, DigitalOcean, and bare-metal environments.

Phishing & Social Engineering Campaigns

Bespoke phishing simulations, pretexting calls, physical tailgating assessments, and USB drop tests. Full reporting with staff awareness metrics and recommended training paths.
