What is penetration testing?

Penetration (pen) testing, is the assessment of computer networks, systems, and applications to identify and address security flaws.

3Columns is an award-winning provider of pen testing services. Our CREST pen testing engagements assist organisations in effectively managing cyber security risk by identifying, safely exploiting, and assisting in the remediation of vulnerabilities that could otherwise result in malicious attackers compromising data and assets.

Comprehensive Pen Testing Services

Web Application Pen Testing

Web application pen testing entails a systematic series of steps to gather information about the target system, identify vulnerabilities or flaws, and research exploits that will succeed against those flaws or vulnerabilities and compromise the web application.​

Mobile Application Penetration Testing

Mobile app pen testing is a simulated attack to identify security flaws in your company's iOS or Android apps. Our CREST-approved mobile app pen tests include an assessment of both the application on the mobile device and the back-end web services (API) that support the application.

External Infrastructure Pen Testing

An external infrastructure pen test examines your network for vulnerabilities and security flaws. It encompasses identifying vulnerabilities in the defined external infrastructure and delivering a report. The report contains an ordered list of issues, associated risks, and remediation advice for identified threats.

Cloud-Based Pen Testing

Cloud Pen Testing is a legally sanctioned simulated cyber-attack on a system hosted on a Cloud provider, such as Amazon's AWS or Microsoft's Azure. The primary goal of a cloud penetration test is to identify a system's weaknesses and strengths so that its security posture can be accurately assessed.

Wireless Pen Testing

Wireless penetration testing entails identifying and inspecting the connections between all devices connected to the company's Wi-Fi. Laptops, tablets, smartphones, and other internet of things (IoT) devices are example of these devices.

Internal Infrastructure Pen Testing

An internal network pen test determines what an attacker could do with initial network access. An internal network pen test can reflect insider threats, such as employees acting maliciously on purpose or unintentionally.

Frequently Asked Questions

Penetration testing is a way of demonstrating reasonable efforts made to test the integrity of your business infrastructure and applications. It shows your company has put effort into protecting confidential and sensitive business data from regulators such as ASIC or AUSTRAC. With new legislation passing in Australia, businesses must demonstrate they’ve regularly checked that their systems comply with industry standards. That checks have been made to ensure there are no vulnerabilities attackers can easily utilise.

A penetration test (or pen test) is a series of intentional attempts to gain unauthorised access through specialised tools available to attackers and professionals. It is like a stress test for your business systems and applications. It assesses the integrity of your business, ensuring confidential data is secure, access permissions are appropriate, and applications are compliant with the latest patches and free from vulnerability of exploits.

An external service provider should conduct penetration tests to ensure there is no bias in the testing and that it is run independently from the business by technical experts familiar with the latest exploits and international and industry standards.

A penetration test can take anywhere from one to three weeks to complete. The type of test determines the length of a penetration test, the type and number of systems being evaluated, and the strength of your existing cybersecurity.

Every organization has different testing needs, and pen testing pricing varies depending on the type of test performed and the overall objectives and duration. The costs of pen testing are ultimately determined by the issues and requirements identified during the scoping phase.
