What is CREST Penetration Testing?
CREST pen testing is the gold-standard accreditation and certification body for the cyber security industry.
Having been awarded CREST accreditation for pen testing and vulnerability assessment, CloudTech24 are perfectly placed to provide CREST penetration testing and improve your organisation’s cybersecurity posture.


Our pen testers simulate cyber attacks to support businesses in developing best practices and ensuring regulatory compliance.
Our red team use evolving processes and testing procedures to assess well-established and emerging threats and their potential to gain access to client systems and networks.
A detailed report is developed throughout the penetration testing to support the improvement of your organisation’s security posture. This information is designed to advise on actionable changes that should be made to your organisation’s security controls.
CloudTech24 provides a CREST registered and approved penetration testing service. Member organisations of CREST are required to demonstrate the highest technical standards and pass rigorous exams to acquire professional-level certification.
All CloudTech24 staff are vetted and supported so that their development is ongoing. Our procedures relating to penetration testing are constantly reviewed to ensure we exceed the expectations bestowed by our CREST accreditation.

CloudTech24 CREST Penetration Testing Services

To identify weaknesses before attackers do, CloudTech24’s security operations centre carries out penetration testing assessments by organising a coordinated real-time simulated cyber attack using our CREST-accredited team of ethical hackers to attack business systems.
This simulated cyber attack aligns with penetration testing frameworks and provides this assurance for the purposes of business safety and compliance.
We offer a fully consultative service to work with your business to understand your current cyber incident response process and provide both data security remediation advice and data protection guidance.
We do this by understanding your environment, limitations, business requirements, and consequences of poor cybersecurity protocols.
Our pen testing services identify vulnerabilities and measure their effect through safe exploitation. Based on your objectives, our penetration testing can be either:
External Penetration Test – Our security experts target your internet facing business assets using specialist penetration testing tools to identify security vulnerabilities and weaknesses that could be leveraged by an attacker at your network perimeter.


Internal Penetration Test – Our security professionals simulate an attack in your internal network and behind the firewall. This provides insight to vulnerabilities of business systems that communicate with external networks or systems that attackers may have direct access to upon local network access via a successful system compromise or direct network access.
CloudTech24 formalise the statement of work with the security consent needed before performing any testing work – this statement makes sure all participants are aware of the process, timelines, and assessment scope.
Testing Process
Throughout the testing process, our pen testers collate all testing stages and findings into the main report which will outline the necessary action that you must take in the short-term.
The report includes insights for essential measures that you should take as part of an ongoing strategy to minimise security risks and reduce the chance of a successful cyber incident to a minimum.
Post technical delivery we provide clients with a formal penetration test report that contains details on your current security posture, along with remediation advice and mitigation strategies.


If it is determined that there is reassessment required, CloudTech24 offer retest penetration testing services to validate remediation of vulnerabilities previously identified in the initial penetration test report.
We also perform social engineering assessments to measure the susceptibility of staff members of clicking a targeted email; this identifies the risk of employees clicking on suspicious links and phishing campaigns and allows for tailored staff security training.
Why are penetration tests important? Does my business need a CREST penetration test?
Companies are increasingly reliant on technology. There is a need to make sure these technology systems are secure from malicious attackers as, if a breach does occur, they could compromise the integrity and operations of your business.
Pen testing is an essential part of improving your company’scyber security position.
It is recommended that these assessments are performed by third parties with internationally recognised accreditation.
Identifying Weaknesses

CREST accredited cyber security services and penetration testing means that your sensitive data will only be available to highly skilled CREST registered testers.
All of our practices are best in class, from assignment execution to delivery and reporting.
Cybersecurity services are constantly changing and evolving in order to assess the latest vulnerabilities and CREST certification demonstrates an organisations ability to be proactive and deliver services of the highest calibre. CREST-accredited companies agree and adhere to a process for resolving complaints.
One of the many benefits of CREST penetration testing with CloudTech24 are that we offer a consultative method of validating your existing security controls and assessing and identifying weakness that could be exploited in the real world. These could have detrimental effects to your business, such as:
- Loss of client trust
- Damaged reputation
- Loss of income
- Loss of confidential information
- Compliance violations
- Information Commissioner’s Office (ICO) fines


How are penetration tests done?
Penetration Tests (CREST penetration testing or otherwise), or pen tests, are simulated attacks on your organisation’s internal or external network.
This ethical hacking exercise assesses your organisation’s internal network and security perimeter to validate software patch levels, services, and configuration through the granular assessment and identification of weaknesses that attackers could exploit.
The CloudTech24 penetration tester provides a detailed pen test report that will include information gathering, a proof of concept of exploitation, details on the test performed, impact and how to remediate these security flaws. It only takes a single misconfiguration or security vulnerability in your computer infrastructure for a cyber attacker or hacker to gain access to your organisation and compromise your data.
What are the benefits of penetration testing?
Our pen testing experts and CREST penetration testing methods together ensure best practice. Proactively performing network pen testing of your organisation is the first step in data protection and information security.
It has the aim of identifying vulnerabilities within your organisation before they can be located and used to gain unauthorised system access or leverage an attack.

Benefits of network pen tests include:
- Identify potential known vulnerabilities, unknown vulnerabilities, and security weaknesses in your target systems through manual assessment that cannot be detected using automated security systems.
- Assess security hygiene of your network infrastructure inline with industry and compliance regulation requirements.
- Establish trust in your information security program and testing process with demonstrable cyber security validation, helping to pre-empt client expectations and investors and auditor requirements.
- Validation of security hygiene and the effectiveness of your current information security approach.
- Risk assessment through the detection and discovery of security risks. We can then mitigate against these before these can be leveraged by an attacker.
- Validate your networks and system security against both known and unknown threats and reduce your attack surface.

What is meant by penetration testing?
A network pen test is a type of security assessment which simulates a cyber attack on a computer system or network in order to evaluate its current level of security through the identification of vulnerabilities, validation and measuring the impact through exploitation from an ethical hacker.
CloudTech24 have CREST certification meaning that you can be sure of the quality of our service. We have over 15 years of experience working with a variety of businesses and their technical information security.
How is penetration testing done?
Penetration testing is a complete assessment performed by a team of security experts using a variety of manual testing and specialised security software. It is done to assess your IT infrastructure to discover potential vulnerabilities which are then manually validated through exploitation by our security professionals.
What is the goal of penetration testing?
A penetration test, or pen test, is an attempt to evaluate the security of an IT infrastructure by safely trying to exploit vulnerabilities. These vulnerabilities may exist in operating systems, services and application flaws, improper configurations or risky end-user behavior.
How much does a penetration test cost?
CREST penetration test costs are based on the scope of the assessment. If you let us know your pen test requirements in our scoping form (available here) we can provide a full pen testing quote. Only once we understand the quantity of IP addresses or network ranges can we provide you with costs aligning to your network assessment requirements. Get in touch to learn more.
How often should you pen test?
We recommend companies carry out at least one CREST certified penetration test per year in order to secure their network perimeter and computer systems. If your business is a software development company, or uses custom web applications, CREST certified penetration testing should be built into the QA process for any major software releases. CloudTech24 also provide Vulnerability Management services to perform interim assessments for businesses between network penetration testing services.
What is CREST and their penetration testing?
CREST penetration testing is pen testing provided by a business with CREST certification. In itself it is not a methodology but validation of excellent provision.
What is CREST certification?
CREST certification is provided by CREST as acknowledgement of a cyber security company’s high standards. It validates that a business delivers services of excellent quality and abides by organisational charters.
What are the 3 phases of penetration testing?
Broadly speaking there are three phases in so far as there is a pre-attack phase, an attack phase, and a post-attack phase. Specifically, however, various other sub phases exist, such as scoping and reconnaissance in the pre-attack phase, as well as remediation advice and reporting in the post-attack phase
