Why procure CREST Penetration Testing services?
As a CREST member company, procuring security services assures of high technical standards and professional code and conduct we need to adhere to. Penetration testing helps to identify security vulnerabilities, and to what extent your organisational assets (people, process and technology) are exploitable and can then take the necessary steps to reduce the cyber risk.
This type of security testing, also known as ethical hacking, is more about manual approach and is targeted to find vulnerabilities in real-world scenarios outside the reach of vulnerability scanners or a vulnerability assessment (see FAQs below).
Our cyber security services are tailored to help your business stand against data security incidents such as data breaches and cyber attacks.

Pen Testing Vulnerabilities
Effective patch management plays a critical role in the closing window of opportunity for attackers, thats between the vulnerability disclosure and patch release.
Domain controllers design and configuration issues, group policy security review including audit policy, account lockout policy, user rights and security settings.
Logging and monitoring controls are reviewed to identify flaws in event collection, analysis and threat identification.
Application configuration errors, input validation, broken controls, authentication & session management checks.
Authentication vulnerabilities found by our penetration testing company are one of the most critical and important attack vectors. This area includes multiple test cases i.e. transmission channels, nature of the input, insecure configurations, weak credentials & bypass attempts.
Based on our methodology and the scope of the job, We perform two types of password reviews which include password policy reviews and a password cracking exercise followed by statistical analysis to find out the complexity & character patterns in use.
Searches are performed on local and network shares for interesting files, contents that would contain credentials and/or any sensitive information.
OWASP pen test Top 10 flaws such as authorisation, input validation, injection issues such as Cross site scripting, SQL injection, XXE, session management & encryption vulnerabilities. Similarly, OWASP API top ten flaws are also included as part of our testing methodology.

UK's most trusted Penetration Testing Service Providers
Our understanding of how threat actors operate helps customers to tackle cyber threats in their business context.
Assessment methodology defines the depth and breadth of how and on what basis test cases are generated. Cyphere’s pen-testing engagement methodology, also known as Vulnerability Assessment and Penetration Testing (VAPT) services, is broken down into five phases:
Initial Scoping & Objectives Agreement
This is a conversational phase to go through pain points/primary security concerns and discuss the assets in scope, out of scope and the objectives for the security test. Communication protocols, fragile components, third-party service providers authorisation, pre-requisites and planning falls into this phase.Reconnaissance
The recon process involves collecting information about the target network, application, systems or devices as much as possible. This sets the ground for attack layout preparation.Scanning
This is an activity aimed at finding what services (such as email services, web services hosting applications, file transfer services/protocols) are running on each of the targets in scope of penetration testing service providers. Activities such as network mapping, service enumeration, vulnerability scanning are part of this phase to identify network and operating system vulnerabilities.Exploitation
The vulnerability exploitation phase involves exploiting the identified vulnerabilities to measure the extent of the breach of a security vulnerability. It is performed in a controlled manner, keeping in view the fragility of the assets in scope and agreed objectives. Password testing (cracking & analysis), vulnerability research, lateral movement, post-exploitation activities belong to this section.Reporting
This is amongst the most important parts of any security test. The information must make sense to customers investing their time and resources. All our reports include raw data, supporting screenshots, tactical and strategic recommendations, management reports and technical reports. There is a debrief call at the end of every security assessment to ensure the customer has an understanding of the findings and have a remediation plan in mind.Remediation
This is an optional remediation consultancy offered in pen testing services to help mitigate cyber security risks to the relevant asset identified during internal penetration testing or any other security testing service. Due to security skill-set and environmental complexities faced by organisations, our approach involves risk focussed approach towards risk remediation.Cyber security penetration testing services
