PENETRATION TESTING

Frequently Asked Questions

Penetration testing, also known as ethical hacking, is a cyber security process in which professionals simulate cyber-attacks on an organisation’s systems to identify vulnerabilities. The objective is to find security weaknesses before malicious attackers can exploit them, allowing organisations to improve their defences. Explore our What is Penetration Testing blog to learn more.

CREST (Council of Registered Ethical Security Testers) is an internationally recognised certification body that accredits cyber security professionals and companies. CREST certification assures clients that their penetration testers have met high standards in both skills and ethics, delivering reliable and effective testing services. Our blog has more information on the difference between CHECK and CREST.

The primary purpose of penetration testing is to assess and improve an organisation’s cyber security posture. By identifying and addressing potential vulnerabilities, penetration testing helps organisations prevent data breaches, protect sensitive information, and comply with regulatory requirements. You can learn more about the ethics of pen testing on our blog.

Penetration testing typically involves several stages: planning and scoping, where objectives are defined; reconnaissance, where testers gather information; exploitation, where vulnerabilities are tested; and reporting, where findings are documented with recommendations. This process helps organisations understand their risks and take action to secure their systems.

To achieve best -practice penetration testing, organisations should conduct penetration testing regularly and frequent testing may be necessary for industries handling sensitive data or for organisations experiencing rapid changes, such as new infrastructure or software deployments. Regular testing is essential to maintaining cyber security resilience.

The five key stages of penetration testing are: Planning and Scoping – Defining the test’s objectives and scope. Reconnaissance – Gathering information about the target systems. Exploitation – Attempting to exploit identified vulnerabilities. Analysis and Reporting – Documenting findings and providing recommendations. Remediation and Retesting – Fixing vulnerabilities and conducting retests to ensure security.

Penetration testing helps organisations improve security, comply with regulations, and reduce the risk of costly data breaches. It also provides actionable insights into vulnerabilities, allowing organisations to bolster their defences, protect their reputation, and build trust with clients and stakeholders.
