Introduction to Penetration Testing

Cyber threats are evolving at an unprecedented pace, and vulnerabilities within your systems can expose your organisation to significant risks. Penetration testing (pen testing) is a proactive security measure designed to simulate real-world cyber-attacks, identifying weaknesses before malicious actors can exploit them.

At IntaForensics, our CREST-certified penetration testing services help businesses strengthen their cyber security posture by conducting controlled and ethical security assessments. Our experienced testers uncover vulnerabilities and provide comprehensive reports with actionable recommendations, ensuring your systems remain resilient against cyber threats.

“Half of businesses (50%) and around a third of charities (32%) report having experienced some form of cyber security breach or attack in the last 12 months. This is much higher for medium businesses (70%), large businesses (74%), and high-income charities with £500,000 or more in annual income (66%).”

Infrastructure Penetration Testing

Your IT infrastructure forms the backbone of your organisation, connecting users, systems, and data. However, without proper security measures, it can become a prime target for cybercriminals. A single weakness in your network could allow an attacker to gain access, move laterally, and compromise critical assets.

Our Infrastructure Penetration Testing service simulates a real-world cyber-attack to evaluate your organisation’s external and internal defences. By identifying vulnerabilities, misconfigurations, and security gaps, we provide actionable insights to strengthen your security posture and mitigate risks.

Mobile Application Penetration Testing

Mobile applications are a key part of modern business, but they also present unique security risks. A single vulnerability can expose sensitive data, compromise user privacy, and create opportunities for attackers to infiltrate systems.

At IntaForensics, our Mobile Application Penetration Testing service simulates real-world attacks to uncover vulnerabilities in iOS and Android applications. Using manual and automated techniques, our CREST-certified security specialists identify weaknesses and provide actionable recommendations to enhance security.

Wi-Fi Penetration Testing

Wireless networks are often the weakest link in an organisation’s security infrastructure. Poorly secured Wi-Fi can allow cybercriminals to gain unauthorised access, intercept sensitive data, or exploit misconfigured devices.

At IntaForensics, our Wi-Fi Penetration Testing service simulates real-world attacks on your wireless infrastructure, identifying vulnerabilities before they can be exploited. Using manual and automated testing techniques, our CREST-certified specialists provide comprehensive security assessments and actionable recommendations to enhance your defences.

PCI Penetration Testing

Handling payment card data comes with strict compliance obligations. The Payment Card Industry Data Security Standard (PCI DSS) requires businesses to safeguard cardholder data, reducing the risk of fraud, breaches, and financial loss.

Our PCI Penetration Testing service simulates real-world cyber-attacks to assess your Cardholder Data Environment (CDE), identifying vulnerabilities and ensuring compliance with PCI DSS standards. Conducted by CREST-certified security specialists, our testing provides actionable remediation insights to strengthen your security posture.

FAQs: All You Need to Know

What is penetration testing?

A penetration test is a manual security test performed on a computer system to find vulnerabilities that malicious attackers could exploit. Penetration testing involves using the same tools and techniques as attackers to identify security weaknesses and help organisations fix them before they’re exploited in real-world attacks.

Why is penetration testing important?

Penetration testing helps identify security vulnerabilities in a system before real-world attackers can do so. Simulating real-world cyberattacks using the same tools and techniques as attackers allows organisations to assess the effectiveness of their defences, uncover potential risks, and implement fixes to strengthen security. This proactive approach helps to reduce the likelihood of breaches, protects sensitive data, and ensures compliance with security regulations.

How does penetration testing differ from vulnerability scanning?

A penetration test involves skilled professionals who, through a mix of manual and automated tests, provide a realistic assessment of an organisation’s security posture, identifying how vulnerabilities can be exploited in practice and providing deeper insights into the potential business impact of each vulnerability. While vulnerability scans help find known vulnerabilities, penetration tests simulate real-world attacks and help provide more actionable and context-rich findings, making them a superior choice when in-depth security evaluation is needed.

What are the different types of penetration testing?

The main types of penetration testing are web application, external, and internal penetration testing. Web application penetration testing focuses specifically on assessing the security of web applications. External penetration testing involves assessing the security of an organisation’s external-facing systems, such as websites, servers, and network devices. Internal penetration testing is conducted from within the organisation’s internal network. It involves simulating an attack by a person who already has some level of access to the network, such as a disgruntled employee or a compromised device (this is a common scenario due to the prevalence of phishing attacks).

What is the difference between black, white, and grey box testing?

A penetration test can be conducted from three perspectives: black box, white box, and grey box. Each perspective reflects how much information and access an assessor has during a penetration test. Black box testing involves no prior knowledge of the system’s internal workings. The tester approaches the system as an external attacker would, using only publicly available information. Grey box testing is a hybrid approach where the tester has some knowledge of the internal structure. This can include limited access to system architecture diagrams, credentials, API documentation, or a basic overview of the network. White box penetration testing involves a comprehensive and detailed level of information provided to the tester. This includes source code, network architecture, IP addresses, operating systems, protocols, etc.

Can penetration testing be automated?

Automated tools can quickly identify known issues, but manual testing is essential to uncover complex, hidden vulnerabilities and simulate more sophisticated attacks. A combination of both automated tools and skilled human testers provides the most comprehensive results.

What's included in a penetration test report?

Our reports are in an easy-to-understand format so developers and other staff can quickly address the identified issues. Each vulnerability discovered during testing will be laid out in a simple-to-understand format within the report. This includes a detailed description of the vulnerability, the risk it poses to the organisation, instructions on how to reproduce it, and resources and advice on resolving the issue. Following the report’s publication, we will arrange a meeting to discuss all the problems raised.

Can penetration tests be conducted remotely?

Yes, we accommodate remote testing.

Do you provide retesting?

We offer free retesting of any vulnerabilities discovered during a penetration test. The report will then be amended to show which vulnerabilities have been addressed. There is no time limit imposed for retesting

Who performs the penetration testing?

Our certified testers perform all penetration tests. Our testing team is highly skilled and experienced in testing various technologies. The IntaForensics testing team hold the following certifications:

  • OSCP (Offensive Security Certified Professional).
  • CPSA (CREST Practitioner Security Analyst).
  • CRT (CREST Registered Penetration Tester).

As part of our accreditation process, CREST has reviewed and approved our methodology for penetration testing.
