Types of penetration testing

Our experts will guide you on the best choice of penetration testing for your organisation, depending on your specific challenges and business priorities.

Web and mobile app penetration testing

Our expert consultants assess the application and attempt to identify and exploit vulnerabilities within the agreed scope. This is a largely manual assessment although some automated tools may be used.

A vulnerability in an application may lead to other elements of the environment being included in the assessment. Typically, the requirement would be to determine the full extent of access or penetration and so the scope would be far wider than the single application.

Cloud penetration testing

Cloud-based systems such as AWS and Microsoft Azure are fast becoming the norm for many organisations and to consider these environments safer than previous online environments would be naïve.

A cloud penetration test is a proactive approach to defending against cyber threats. It is a simulated cyber-attack designed to assess the strength and weaknesses of a cloud infrastructure and ultimately improve the overall security posture.

A&O IT Group’s team consists of CREST accredited penetration testers who are experienced in working with AWS, Microsoft Azure and other cloud environments.

External and internal network penetration testing

Choose from white, grey or black-box testing.

With black-box testing, we start with no prior knowledge of the network or specific brief, which simulates the approach of real-world hackers.

With white-box testing, we have privileged information about your network and some agreed areas of focus.

Grey-box testing comes somewhere in between as we work with limited information, such as the topography of the network to uncover critical issues like admin access.

Physical penetration testing

A physical penetration test is a set of simulated attacks performed by our experts to identify weaknesses in your organisation's physical security. This exercise consists of evaluating the security controls and bypassing any physical or electronic security measures to gain access to secure areas. Consultants will advise where insufficient security controls are in place. This includes looking for insufficient CCTV coverage, along with insecure locks and windows. Physical security assessments could also involve consultants being escorted around the premises.

Browser exploitation

Browser exploitation is a client-side attack that attempts to discover and exploit vulnerabilities either in or through the web browser, not just the network perimeter and client system. This is a technique often used by Advanced Persistent Threat (APT) groups and can provide a foothold for further attacks. Our assessment can consider multiple web browsers and use them as a base for instigating command modules and advanced attacks against the system from within the browser context.

Infrastructure penetration testing

Our consultants assess the internal or external infrastructure and attempt to identify and exploit vulnerabilities within the agreed scope. We will attempt to discover vulnerabilities such as weaknesses caused by misconfiguration, and unpatched firmware or software, using a mixture of automated software, manual analysis and our wealth of experience in this area.

Our experts will gather information from public sources, as well as from both passive and active scanning of the infrastructure.

Wi-Fi intrusion & spoofing

Consultants assess the security of the Wi-Fi network, looking to confirm the use of a suitable encryption scheme. Where a pre-shared key is used, the strength of this would be assessed.

Among other things, we consider network segregation, access to other networks, and applications available through the Wi-Fi network. We would also look at spoofing (otherwise known as the evil twin attack), creating an access point with the same SSID as the network to trick users.

Social engineering

Social engineering involves hackers manipulating people from within an organisation into carrying out damaging actions or divulging valuable information.

Our CREST-accredited team have spent more than 23 years protecting businesses like yours from this kind of threat, which includes everything from phishing to social media information leakage. Our experts provide a bespoke range of real-world social engineering services to highlight issues, provide vital metrics and identify weak spots that could be exploited.

What is penetration testing?

Penetration testing involves running a simulated cyber-attack across all your organisation’s systems, including networks, software, apps and websites. In this case, of course, the cyber-crime experts are on your side. Our aim is to find all the security vulnerabilities an attacker could exploit before they have the opportunity to do so.

Who will carry out my security testing?

A&O IT Group’s CREST-approved penetration testers rank among the most respected in the industry, so you can be sure your assessment will be carried out to the highest possible standard. A number of our security consultants are active contributors to industry publications and white papers, and they are all well-established within the infosec industry.

What is in my penetration testing report?

Our bespoke report will provide you with concise analysis of security vulnerabilities and associated threat levels, along with remediation advice. Our complimentary executive and technical presentations are provided as standard, so you will have ample opportunity to discuss our findings directly with the consultant who carried out your testing. 

How often should my organisation carry out penetration testing?

Due to the threat landscape constantly evolving, penetration testing should be performed on a regular basis. It’s recommended that all organisation’s carry out a penetration test at least once a year but there are many reasons why more frequently would be recommended. When you make changes to infrastructure, for example, or in preparation for compliance standards.

What is the difference between penetration testing and red teaming?

Whilst penetration testing and red team assesments are related and often confused, they od have their distinct differences. 

Penetration testing has a focused scope, often limited to a system or application. The aim is to find and remediate vulnerabilities that a malicious attacker could expolit - thus lowering the threat.

A red teaming assessment is a wider approach aimed at testing an organisation's overall security posture using the latest tactics, techniques, and procedures (TTPs) to access their crown jewels.

We took a deeper dive into the difference in our blog Penetration Testing vs. Red Teaming - What's the difference?
