External Network Penetration Testing

Identify and mitigate external vulnerabilities to safeguard your organisation against cyber threats originating from outside your network perimeter.​ 

Why Your Organisation Needs External Penetration Testing?


External threats pose significant risks to organisations, with attackers constantly probing internet-facing systems for exploitable vulnerabilities. Without regular assessments, your organisation may be susceptible to data breaches, financial losses, and reputational damage. External penetration testing simulates real-world attacks from outside your network, evaluating the effectiveness of your perimeter defences and identifying areas for improvement.​

Common FAQs on

External Penetration Testing

  • What is external penetration testing?

    External penetration testing involves evaluating an organisation's internet-facing systems to identify vulnerabilities that could be exploited by external attackers. This process helps ensure that external defences are robust and capable of withstanding real-world cyber threats.​ 

  • How frequently should external penetration testing be performed?

    It's recommended to conduct external penetration testing at least once a year or after significant changes to your external-facing systems. Regular testing helps detect new vulnerabilities and ensures ongoing protection against evolving cyber threats.​ 

  • What types of vulnerabilities are commonly found during external penetration tests?

    Common vulnerabilities include misconfigured firewalls, unpatched software, weak authentication mechanisms, exposed services, and insecure web applications. Identifying and addressing these issues is crucial to prevent potential exploitation by cyber criminals.​ 

  • How does external penetration testing differ from internal testing?

    External penetration testing focuses on assessing the security of systems accessible from outside the organisation, such as websites and email servers, to protect against external threats. In contrast, internal penetration testing evaluates the security of systems within the organisation to address insider threats and potential breaches originating from within.​ 

  • Will external penetration testing impact our live systems?

    CyberUnlocked conducts external penetration tests with utmost care to avoid disrupting live systems. Our team works closely with your IT personnel to plan and execute assessments during suitable timeframes, ensuring that testing activities do not interfere with normal business operations.​ 

  • How does external penetration testing support Essential Eight compliance?

    External testing helps assess how well your organisation is implementing key Essential Eight controls like patching, system hardening, and restricting admin access. It’s a practical way to measure maturity and improve your cyber resilience against external attacks.
