What is Penetration Testing? A Complete Guide for Businesses
Penetration testing — often called a pentest — is an authorised, controlled security assessment where security experts attempt to find and exploit vulnerabilities in your systems. The goal is to identify weaknesses before malicious actors do, and provide concrete recommendations for remediation.
Unlike automated vulnerability scanners, penetration testing goes deeper. Security experts think like attackers — they test business logic, attempt to bypass access controls, and find issues that automated tools miss. The result is a report with prioritised findings and practical recommendations.
There are several types of penetration testing. Web application testing focuses on OWASP Top 10 vulnerabilities such as injection, broken access control and security misconfiguration. API testing covers REST and GraphQL endpoints, authentication and authorisation. Network testing examines infrastructure, firewalls and internal systems.
At Awareness Security, we specialise in web application and API testing. We use AI-assisted vulnerability scanning combined with thorough manual testing. All analysis runs locally on controlled infrastructure — no data is sent to external AI providers such as OpenAI or Google.
Our Human-in-Control process ensures quality through four checkpoints: authorisation, attack plan, validation and delivery. The customer has full visibility throughout the process and approves scope and testing window before we begin.
What does penetration testing cost? The price varies based on scope and complexity. A typical web application test takes 1-2 weeks. We always provide a tailored quote after an initial conversation about your needs.
When should you conduct penetration testing? Before launching new applications, after major changes, as part of compliance requirements (ISO 27001, GDPR), or as a regular security assessment. Most organisations should test at least annually.
