Penetration Testing Services
Our Crest accredited Penetration Testing identify and eliminate vulnerabilities, giving you peace of mind and protecting your bottom line.

Uncover Your Vulnerabilities & Strengthen Your Infrastructure
Traditional Penetration Testing methods often fail to provide the robust, year-round defence your business requires. The predictable patterns and repetitive formulae can restrict innovative insights, overlook critical areas and lead to formulaic reporting that might miss emerging threats.
At CyberOne, we don’t settle for the status quo. Our Penetration Testing services continuously evolve to keep pace with the rapidly changing cyber security landscape.
We customise our Penetration Testing to match your business environment, ensuring a comprehensive and up-to-date defence system that protects your valuable digital assets.

Types of Penetration Tests We Offer
Our expert ethical hackers use advanced tools and techniques to assess networks, applications, endpoints and wireless systems. We conduct:
External Network Testing
Evaluate the effectiveness of your perimeter security controls to prevent and detect attacks. This test identifies vulnerabilities in internet-facing assets such as web, email and FTP servers.
Internal Network Testing
Assess the potential impact of lateral movement within your network. This simulation mirrors insider threats, whether intentional or accidental, to reveal the extent of internal vulnerabilities.
Web Application Testing
Detect data leakage points within your web applications. We examine your source code for adherence to best practices and check for bugs, particularly during the design phase.
Mobile Application Testing
Identify platform-specific vulnerabilities in Apple and Android environments. Our assessments expose insecure mobile app functionalities and suboptimal security strategies.
Wireless Testing
Uncover weaknesses in your wireless architectures to prevent unauthorised network access and data leakage.
Social Engineering Testing
Test your employees’ security awareness by simulating phishing emails, credential theft and unauthorised computer access, ensuring robust human-centric security controls.

Reporting & Debrief
Our experts write an in-depth Penetration Test report with clear recommendations and guidance for remediation, available for delivery in written, virtual or face-to-face formats.

Penetration Testing Has Moved On.
Have You Moved With It?
The landscape of cyber threats isn’t what it used to be. With the rise of hybrid working, shifting business infrastructures and advanced threats from nation-state actors, the traditional once-a-year Penetration Testing simply doesn’t cut it anymore. It’s time for your Penetration Testing strategy to adapt and evolve.
It’s not just about increasing the frequency or speeding up the process, but also about embracing automation, refining methodologies and aligning more closely with your business needs. Explore our insights and advice in this quick read on how you can step up your Penetration Testing game.

Key Drivers for Cyberone Penetration Testing
With CyberOne Penetration Testing, we evaluate your networks, applications, endpoints and users against both internal and the latest external threats. The insights gleaned from our Penetration Testing enables you to shore up your security strategy and plug any holes in your system.
Assess Your Risk
Risk assessments, complemented by comprehensive penetration testing, enable you to stay proactive in identifying and managing potential vulnerabilities. By adopting a continuous assessment strategy, you are taking the essential steps to mitigate risk and ensure maximum protection for your digital assets.
Secure Your Evolving Infrastructure
Whenever you integrate new technologies or expand your organisation, your security profile changes. With Penetration testing, it helps to reveal any potential weak spots or security misalignments that may leave your systems exposed. Stay ahead of the threats and ensure your evolving infrastructure remains well protected.
Determine Improvements, Reduce Risks
Penetration testing consistently identifies areas of weakness in need of remediation. Armed with the insights from the penetration test report, your organisation can determine necessary improvements, shaping a plan to reduce exposure to risks.
Navigating Security Risks in Business Expansion
Inheriting an IT network through business acquisition introduces fresh risks. Comprehensive penetration testing swiftly pinpoints pressing issues that need resolution. Additional security assessments are strongly recommended prior to merging systems or transferring data.
Build a Case for Increased Spending
If you’re aware of issues that need remediation, but struggle to get the sign-off on additional spending, penetration testing offers clear, compelling evidence to bolster your argument. The results help to direct funds towards the most critical issues and serve as a starting point for discussions around other important but less immediate concerns.
Instill Confidence in Clients, Partners and 3rd Parties
Penetration testing fosters trust from current and potential clients. It demonstrates your active efforts to reduce the risk of a breach, using an independent third party to examine your security protocols.
Fulfil Compliance and Regulatory Obligations
For certain industries, penetration testing isn’t optional; it’s a necessity. These penetration tests serve as evidence that you’re actively maintaining a robust cyber security posture and managing potential risks. Not only will this help you stay compliant, but it also assures your stakeholders that their data is being handled with utmost care and security.
Case Study
Elcoin
In a strategic partnership, Elcoin engaged CyberOne to validate and enhance their cyber security posture. Leveraging our banking sector expertise, CyberOne provided a comprehensive Penetration Testing service.

Frequently Asked Questions
What is Penetration Testing?
Penetration Testing, also known as a Pen Test, is a security assessment technique where authorised individuals simulate real-world attacks on computer systems, networks, or applications to identify vulnerabilities and weaknesses that hackers could exploit.
Why Is Penetration Testing Important?
Penetration Testing helps organisations identify security vulnerabilities and assesses their overall security posture. Penetration Testing identifies weaknesses in systems and applications allowing organisations to improve their overall security.
How Often Should Penetration Testing Be Conducted?
The frequency of Penetration Testing depends on various factors, including the size of the organisation, the industry, the sensitivity of data, and the rate of change in the environment. It is generally recommended to conduct Penetration Testing annually or whenever significant changes occur in the system or network.
What Are the Benefits of Penetration Testing?
Penetration Testing provides organisations with several benefits, we have listed a few below:
- Identifying security vulnerabilities and weaknesses before malicious attackers can exploit them.
- Assessing the effectiveness of security controls and measures.
- Meeting regulatory compliance requirements.
- Enhancing the overall security posture of an organisation.
- Building customer trust by demonstrating a commitment to security.
Can Penetration Testing Cause Damage to Systems or Data?
Penetration Testing should be conducted by professionals who follow strict rules of engagement and ethics to minimise the risk of damage. However, there is always a small potential for unintended consequences. It is crucial to work with experienced testers who take precautions and obtain proper authorisation to minimise any potential risks.
How Long Does a Penetration Test Take?
The duration of a Penetration Test varies based on the size and complexity of the target system, network, or application. It can range from a few days to several weeks, depending on the scope of the assessment. The timeframe is typically agreed in advance with the Penetration Testing service provider.
