External Network
Penetration Testing

Your external network perimeter is the first line of defence against attackers. External network testing can help you discover where you are vulnerable to exploitation, and 
how to remediate these vulnerabilities in order to prevent security breaches.

What is an External Network Penetration Test?

An External Network Penetration Test assesses your public-facing network infrastructure. Vulnerabilities can often arise from misconfigurations, unpatched software or credential breaches. These vulnerabilities can be exploited by attackers, allowing them to disrupt the organisation, gain access to the organisation’s internal network or access confidential data.

When performing our CREST-accredited External Network Penetration Testing, we use a range of in-depth manual and automated techniques to access external systems or infiltrate your network. We’ll document and prioritise any vulnerabilities exploited and will include clear remediation steps that will help to better secure and protect your external network.

Our external network testing methodologies are built upon industry standard frameworks including NIST SP 800-115 and the Penetration Testing Execution Standard (PTES). Our comprehensive methodologies provide a full coverage evaluation and we will tailor our testing based on the technologies configured and the scope agreed with the client.

Findings are consolidated and prioritised in a report alongside clear remediation recommendations. The report is structured in a way that benefits stakeholders of all levels of technical understanding.

What Makes Our External Network Penetration Testing Different?

  1. All our penetration testing is conducted by CREST qualified, UK based staff, and Predatech is also CREST-accredited at a company level

  2. Predatech clients have direct access to their penetration tester throughout the engagement who’ll answer any questions, provide demonstrations, and work closely with the client team.

  3. At the end of each day of testing, our testers will provide a vulnerability summary of issues identified so far which provides a moving picture of how the engagement is progressing.

  4. We provide complimentary retesting as standard. Once a client has remediated any vulnerabilities discovered during testing, Predatech will retest to ensure that these vulnerabilities have been remediated successfully and we’ll issue an updated report to reflect any changes.

What Does Testing Involve?

Discovering unpatched and end of life software

Discovering any versions of software where an exploit may exist on the public domain

Using breached credentials to conduct credential stuffing, password spraying and brute-force attacks

Abusing misconfigurations to see if they could be used to an attacker’s advantage

Noting any software/hardware information that can be used to fingerprint the technologies running
