What is a Penetration Test?

A penetration test, also known as a pen test, is an authorised attack simulation against an organisations network or applications identifying vulnerabilities and security issues. Vulnerabilities discovered during a pen test are exploited confirming the severity of the issue and compromised machines.

Network Penetration Testing

Network penetration testing also known as network pen testing, is the process of testing an organisations network infrastructure externally or internally to identify vulnerabilities and security issues. After discovery, vulnerabilities are safely exploited, confirming if the vulnerability exists. The testing process is manual, removing false positives typically returned by automated tools and vulnerability scans.

Aptive provide external assessments of an organisations network infrastructure of application, typically testing is performed offsite to simulate the same set of conditions a real-world attacker would have. Working remotely gives our team the flexibility to perform testing out of hours, further reducing impact and risk to the clients organisation.

How does Network Pen Testing help my Organisation?

A full network security audit is performed, identifying both discovered vulnerabilities and issues that are found to be exploitable while testing, this is sometimes referred to as VAPT (vulnerability assessment and penetration testing). Aptive’s security testing services help address regulatory and compliance recommendations / requirements such as PCI DSS, ISO27001 & GDPR.

External Penetration Testing

An organisation is assessed externally at the network infrastructure level, typically with a similar set of conditions a real world attacker would have, making it the most realistic form assessment. Depending on client scoping, compromised machines can be used as a means of advancement, allowing a consultant to use the machine as a gateway into the organisations network and accessing machines behind the corporate firewall.

Internal Penetration Testing

Aptive provide internal testing either onsite or by deploying an appliance allowing our team to connect remotely. Deploying an appliance onsite gives our team the flexibility to perform testing out of hours, reducing impact and risk to a client organisation.


With new cyber security threats immerging every day, an effective defence against attacks is required for businesses of all sizes.

Why is Penetration Testing Important?

Organisations are often unknowingly the targets of automated cyber attacks, many smaller and medium sized businesses who think they are not a target, the classic thought process of “why would anyone want to hack us” unfortunately, SME’s do not realise that most cyber attacks are fully automated, attackers will attempt to breach mass numbers of organisations with automated tools which then report back once they are successful. Our penetration testing services help identify security issues, by providing a severity ordered report, listing discovered vulnerabilities using and ensure help your organisation identify and fix security issues, along with our security recommendations.

Application flaws, incorrectly configured networks and logic flaws are the three major contributors a potential attacker could exploit and gain access to your organisations critical or sensitive data or worse gain a foothold within your network.

Aptive employs a real-world approach to penetration testing, our team of ethical hackers will assess your applications and organisation allowing you to gain a clear overview of the current state of your security and follow our remediation plan to address your security issues.

Manual penetration testing goes a step further than an automated vulnerability assessment and approaches the security assessment manually chaining together discovered vulnerabilities to gain higher severity issues. While automated tools are used during the assessment, these aid the process, the penetration tester is highly skilled and is never dependent upon vulnerability assessment tool output.

Advantages of a Penetration Test

Testing identifies security issues and risks, providing your organisation with a realistic overview of the current state of security, helping assess its current status in relation to various compliance standards. A penetration test goes a step further than automated threat detection and vulnerability assessment, the key benefits are outlined below.

  • Gain an insight to the current state of security – testing will identify a risk and severity ordered list of discovered security issues for your organisation
  • Address compliance requirements – many regulatory and compliance standards such as the GDPR, ISO 27001 and PCI DSS recommend or require a penetration test
  • Protect your companies brand and reputation – by identifying security issues you’re taking a step to help prevent a data breach (the GDPR states all data breaches must be reported no later than 72 hours)
  • Manage resources – using the severity ordered remediation plan, accurately assign your organisations resources to remediate high severity issues first
  • Justify budget – using the report from an expert 3rd party penetration testing company you can reach out to non-technical budget controllers or stake holder and justify additional budgets for resources / hardware to improve your organisations cyber security
  • Test existing controls – many organisations spend large amounts of their budgets implementing security protection devices such as firewalls, web application firewalls and vulnerability management. Testing will help assess if those controls are configured correctly and are working as expected

Why Perform a Penetration Test?

Often companies are unaware of existing vulnerabilities within applications or infrastructure that a potential attacker could successfully exploit, breaching a companies confidential data and damaging brand integrity. Penetration testing discovers and confirms vulnerabilities exist and provides clear instructions allowing your company to fix the discovered security issues.

  • Compliance – Various regulatory compliance standards such as ISO 27001 and PCI DSS require a penetration test annually and after significant infrastructure changes
  • Identify Vulnerabilities – Regular testing identifies security issues and weaknesses within a companies applications and infrastructure
  • Cyber Security Risk Assessment – Understand the level of risk that currently exists for your company, testing identifies and prioritises security risks
  • Test Controls – Execute a real-world attack, testing your network security defences
  • Detect New Vulnerabilities – New security vulnerabilities are publicly exposed every day, regular testing will help identify if your company is vulnerable.
  • Fix Security Holes – Our reports document clear fix instructions for discovered security issues and vulnerabilities

Our Approach

We approach penetration testing using a risk based model, in simple terms; more time is spent on higher risk issues. After the issue has been verified additional time is spent identifying other high-risk issues.

For example, instead of spending large amounts of time attempting to exploit an application that is known vulnerable, that for some reason cannot easily be exploited due to something within your environment blocking or preventing the exploit from running, we would simply document the finding, provide our recommendation based on the fact the application is likely exploitable if more time is spent exploiting the issue.

While some pen testing companies would continue to spend time and fully exploit the discovered security issue, which is always desirable it can quickly use up time that could be spent identifying more issues. Our team would move on identifying more security issues, using our time effectively helps us identify more security issues that could impact your business.

This is approach is situation depending, if the target is a gateway into the organisation’s network or holds sensitive information then additional resources would be assigned.

We provide a detailed breakdown of your security issues and results in an easy to understand report, which provide a executive summary, a technical summary, each issue then contains an issue summary, technical description (including steps to reproduce), business impact, recommendation (remediation instructions and advice), evidence, CVSSv3, Risk Rate Calculation. Additionally, we provide a clear remediation plan for your teams to work through in order to fix the identified security issues. After your team have completed the recommendations we will retest the discovered issues at no additional cost.

How often should you perform a Penetration Test?

Testing should be performed on a regular basis to ensure newly discovered threats and vulnerabilities are discovered and remediated before any potential attacker detects and exploits them in the wild. In addition to regular security assessments demanded by regulatory and compliance standards, network security audits should also be completed when:

  • New changes to network infrastructure
  • External servers or applications are deployed (including cloud / external servers)
  • Significant upgrades or modifications to infrastructure or applications
  • At new office locations
  • After the company acquires other companies (including mergers)
  • After security patching to ensure applications and infrastructure are no longer vulnerable
