Penetration Testing Services
How easy would it be for a hacker to gain access to your IT systems?
CloudTech24 uses the latest pen testing techniques to simulate real‑world attacks and uncover vulnerabilities.
Our bespoke CREST-accredited pen tests deliver clear insights into your security posture and the steps you need to take to strengthen your IT environment.
Why penetration testing matters for your business
As technology and AI evolve, so do cyber-attacks and threats, making it increasingly difficult to protect your systems and networks.
CloudTech24’s penetration testing services use the latest tools, frameworks, and methodologies (including stealth attacks, zero-day exploits, and social engineering techniques) to uncover vulnerabilities and mitigate vulnerabilities within your IT infrastructure.
Also known as ethical hacking or white-hat hacking, the goal is to uncover weaknesses or potential avenues of compromise and assess how each one could be exploited to gain unauthorised access to your company’s sensitive systems and data. The results of your pen test will reveal any gaps in your defences and deliver detailed insights plus actionable guidance on how to enhance compliance and resilience, minimise risk and improve your overall security posture.
Whether you’re a growing business or an established enterprise, penetration testing is essential for staying ahead of cybercriminals and safeguarding your reputation, data, and operations.

Benefits of penetration testing services
There are several clear benefits of pen testing – some of the most important include:

How to choose a penetration testing provider
Selecting the right pen testing partner is an important decision. When evaluating providers, it’s essential to evaluate costs, proven capabilities, reviews and accreditations.
An excellent place to start, is to ensure that all the providers on your shortlist meet recognised security standards, such as CREST. Having relevant penetration testing accreditation ensures the provider has been externally validated for their services and that they follow proven methodologies, employ qualified professionals, and deliver reports you can rely on for compliance and remediation.
We would also recommend you consider the provider’s industry experience, their testing methodologies, and the clarity of their deliverables. You need to ensure you will receive a comprehensive, actionable report that enables your vulnerabilities to be effectively addressed.
Finally, evaluate the providers’ communication and post-test support. The best pentest partners act as trusted advisors rather than one-time vendors.

CREST-accredited
CREST is the gold‑standard accreditation for cybersecurity penetration testing, recognised globally for its rigorous technical, legal, and ethical standards. CloudTech24 is a CREST‑accredited penetration testing provider, validated to deliver high‑integrity security assessments that meet the expectations of regulators and auditors.
Our CREST‑certified penetration testers are vetted, experienced professionals who combine deep technical skill with structured, framework‑aligned methodologies to simulate real‑world attacks against your systems. We continually review our pen testing processes and invest in staff development to ensure our CREST‑accredited services not only meet but exceed the standards set by the accreditation.
Penetration testing process
Our penetration testing services follow a structured process.
The reconnaissance phase
In this phase, our ‘would-be attacker’ gathers information about the target system to decide how best to exploit it later. The information gathered depends on what kind of vulnerability we’re looking for (whether it’s an authentication or configuration problem) and what type of pen test/audit we are performing.
Scanning
The scanning phase consists of identifying vulnerabilities in the target system. Depending on the task, this is done using tools such as Nessus, Nexpose, SNMP check, Hydra, and Metasploit (to name a few) or even manually. Our pen testers will conduct a static or dynamic analysis. If there is an upgrade in the system, the scan will also look for old security patches that a hacker could exploit.
Gaining access
This stage involves accessing the system using information from the scanning stage. Once we’ve identified the entry points, we can exploit these vulnerabilities using techniques like SQL map, Metasploit, SQL injection, etc. This is where we actually perform the ‘attack’ and use the vulnerabilities identified to gain access.
Maintaining access
The tester will try to discover the extent to which the identified weaknesses could be exploited by a hacker. The tester acts as a persistent cyber-attacker trying to access privileged areas of the network. This phase consists largely of maintaining access for as long as possible without being detected.
Covering tracks phase
This element of the pentest requires the tester to be proficient at permanently removing all evidence of the attack. If a real hacker doesn’t do this, then all their hard work could be in vain. Generally, this can be achieved by deleting logs, removing or disabling security software, and hiding files/folders so they can’t be found.
Analysis and reporting
In the final stage, we provide a comprehensive report that breaks down our findings along with a list of prioritised, actionable recommendations to strengthen your security posture.

FAQs: Penetration Testing Services
Take a look at some of the questions we receive about our penetration testing services. If you have a query we haven’t covered, please do contact us.
Who needs penetration testing services?
Cyber-attackers indiscriminately target organisations, so penetration tests are a valuable tool for most businesses. The number of hybrid and remote workers is rising, and with staff accessing sensitive company data from multiple devices, this has an impact on your vulnerability.
How much does penetration testing cost?
The cost of penetration testing depends on a number of factors but is primarily dictated by the scope and complexity of what is being tested, for example, testing a simple web application versus conducting a comprehensive assessment of an entire network infrastructure. Factors such as the size of the organisation, the depth of the testing, and the specific methodologies employed all play a role in determining the cost.
Penetration testing is an investment in proactive security, preventing costs that would be incurred coping with a major cyber-attack.
How often should pen testing be carried out?
The optimum frequency of your pen tests will depend on your organisation size, the sensitivity of your data and any changes you make to your overall security strategy.
A good starting point is once every 3-6 months for smaller businesses with limited liability or less sensitive information. Larger organisations are likely to benefit from pen testing every quarter, especially if implementing new systems or applications or making changes to network infrastructure on a regular basis.
Don’t wait for an annual review to conduct a penetration test. If you are concerned there may be a security flaw in your organisation or network, it is much better to address this immediately.
Is penetration testing legal in the UK?
Penetration testing is generally legal in the UK, but there are some important considerations to keep in mind. It’s crucial to have explicit permission from the owner of the system or network being tested. Unauthorised penetration testing can potentially lead to legal consequences, as it may be considered a violation of computer misuse laws.
What is a PCI pen test?
A PCI pen test, or PCI compliance test, refers to an assessment designed to evaluate and ensure adherence to the Payment Card Industry Data Security Standard (PCI DSS). This standard sets requirements for organisations that handle credit card transactions to protect cardholder data and prevent security breaches.
What is CREST certification?
CREST certification is an internationally recognised accreditation from the Council of Registered Ethical Security Testers (CREST), a non-profit body that sets professional standards for cybersecurity services like penetration testing, incident response, and vulnerability assessments. CloudTech24 has been independently assessed against rigorous standards. We are CREST-accredited for penetration testing and vulnerability assessments.
How does PTaaS work?
As opposed to regular pen tests, which are performed at intervals on a project-by-project basis, Pentesting as a Service (PTaaS) works by running pen tests continuously on a schedule agreed with the client.
CloudTech24 has platforms where we can provide ongoing penetration testing, ensuring your business is regularly evaluated for new cyber-threats and proactively protected.
