Your business is running smoothly.
Sales are flying in, your customers are happy and you feel on top of the world.
What could go wrong, right?
As you will know, in the world of business, many things can and do go wrong. And whilst you’re celebrating a new contract, you may be completely unaware of the cybersecurity flaws that hackers would love to take advantage of.
In just a few minutes, all your hard work and perseverance over the years can be jeopardised, just like that. Cyber attacks can be ruthless and very damaging to your business.
In fact, 68% of business leaders feel that their cybersecurity risks are increasing. Whilst in 2018, 62% of businesses experienced phishing and social engineering attacks.
So, what can you do about it?
One of the most important first steps to take is to analyse the exploitable vulnerabilities that your business may have.

What is Penetration Testing?
A penetration test is a technical exercise aimed at finding weaknesses in a company’s networks, applications or systems. This cybersecurity assurance is provided against an organisation’s assets.
By identifying these security flaws, businesses are able to find out the extent to which their assets (people, process and technology) are exploitable and can then take the necessary steps to reduce the risk.
Penetration testing is also known as ethical hacking, cybersecurity assessment, technical security audit or technical risk assessment. Although often penetration testing and vulnerability assessment are used interchangeably, this may be either due to lack of understanding or marketing hype. Vulnerability scanning and vulnerability assessment search the systems for known vulnerabilities. This is an automated process with the use of scanners. No manual exploitation is part of vulnerability assessment, whereas penetration testing involves manual techniques to exploit the vulnerabilities identified during vulnerability scanning phase.
Why is Penetration Testing important?
You may be wondering, ‘what value is pen testing going to bring to my business?’.
It’s a common question as many people don’t fully understand what penetration testing is. So, let’s go through all the most important reasons as to why pen-testing is a smart business decision.
We now live in a world where data is a more valuable resource than oil. Not only is this huge for our personal lives but in business, your data is one of your biggest assets. Due to the inherent link with technology, threats evolve and change over time.
This means that, while you may have overcome a security issue a year ago, new threats are always on the horizon. For this reason, it is critical to regularly assess your security in order to protect your network.
Develop Your Cybersecurity Strategy
Cybersecurity in any business shouldn’t be an afterthought. A well-thought-out, evidence-based cybersecurity strategy should be integrated into every business looking to be more secure.
The best way to create a cybersecurity strategy is to gather information through security assessments and cybersecurity audits. The data you gather here can then inform your strategy and act as the foundation for your plan.
Once you understand your current threats, you can update your practices, inform employees, streamline your processes and most importantly, improve your technology.
A Proactive Approach
Pen testing is the perfect way for a business to identify weaknesses and vulnerabilities before they are exploited. As we mentioned above, cybersecurity should be an ongoing process for any business.
Pen testing should be performed on regular basis to ensure your most prized assets are always protected. Usually, this is an annual exercise or following any upgrades to code, hardware, software. Having a proactive mindset towards cybersecurity is imperative if you want to have effective results.
By having regular pen tests, you create more efficient business systems, prevent data loss and save your business a lot of potential headaches.
How does Penetration Testing work?
At Cyphere, penetration testing is one of our main offerings for businesses.
The first step in the penetration testing process is to get in touch with a cybersecurity professional or consultancy, such as ourselves.
Customers sometimes think we go off at tangent, understanding your business from you is the most important step. We ensure that gaining business insight and requirement analysis is in line with your business objectives.
This helps us to see how we can build a tailored cybersecurity package for your business. When working with our clients, we are flexible, meaning we can talk face to face or on a video meeting to discuss your requirements. This leads to a bespoke proposal, in order to meet your specific security requirements.
We will then get to work and identify technical risks affecting software and hardware in your business. This test will then add assurance that the products, security configurations and controls are configured in line with good practices.
This information will be presented to you in an easy to understand report that will give you strategic recommendations and help you prepare a mitigation plan for an attack.
Not only do we provide you with a clear plan of action but we also make sure this is communicated effectively at a technical and management level.
What is our Engagement Approach?
Our engagement approach remains focussed on service quality. As you notice on our homepage, our engagement approach is underpinned by three principles: We engage, We listen and We deliver. The following five steps define our engagement process that puts service quality as our top priority:
Customer Business Insight & Requirements Capture
The very first step remains our quest to gain insight into drivers, business, pain points and relevant nuances. As part of this process, we understand the assets that are part of the scope.
It is important to gain grips with the reality, therefore, we always stress on walkthroughs or technical documentation of the assets. After asset walkthroughs, a tailored proposal is designed to meet your business’ specific requirements.
Cyphere’s approach to all work involves excellent communication with technical skill-set. See penetration testing methodology section below for detailed information.
Execution phase is followed by data analysis and reporting phase. Cyphere performs analysis on the testing output, evaluates the risk impact and likelihood of exploitation in realistic scenarios before providing action plans to remediate the identified risks. All our reports address business as well as the technical audience with supporting raw data, including mitigation measures at strategic and tactical levels
Debrief & Support
As part of our engagement process, customers schedule a free of charge debrief with management and technical teams. This session involves remediation plan, assessment QA to ensure that customer contacts are up to date in the language they understand.
What is a Penetration Testing methodology?
In order to perform a security assessment, it is important to understand the context of assets in scope for the engagement.
Penetration testing projects are categorised into three areas on the basis of the level of knowledge and access granted to the security consultants. These are:
- Black Box Penetration Testing : A black box pen test starts with no prior knowledge and access to the target. For example, a website security assessment with no information and user access.
- Grey Box Penetration Testing : A grey box pen test involves some level of knowledge and access to the target. For example, a website security assessment with low level user access.
- White Box Penetration Testing : A white box pen test is granted with the highest level of information and access. For example, a website security testing where multiple user levels including CMS admin and information such as security architecture, design document and/or source code access is supplied to the security consultant.
It is important to select the right assessment techniques as this can influence the outcome of the testing process. In order to simulate threat actors, it is important to consider various threat scenarios that lead to creation of test cases used during one of these three methodologies. Multiple penetration testing frameworks have also been released in the past. These include Open Web Application Security Project (OWASP) for web application assessments, The US Commerce Department’s popular cyber framework from NIST, Open Source Security Testing Methodology Manual and the Penetration Testing Execution Standard. Quite often, due to the content popularity OWASP and SANS Top 20 Critical Controls are often cited as benchmarks for testing methodology.
Our proven approach to security assessments is based on more than a decade of experience, industry practices and effective ways to exceed customer expectations. Cyphere’s pen testing engagement lifecycle is broken down into five phases:
Initial Scoping and Objectives Agreement
This is often overlooked area, however, is one of the most important aspects. No one knows a network better than their caretakers that is THE customer.
Defining an accurate scope of the work ensures understanding and clarity of objectives, exclusions, and what to do if something happens. We ensure that proven project management approach is put to work, ensuring all parties are aware of authorisation forms & legalities, in-scope elements, any fragile components and out of scope components before commencing an engagement.
Once legal and project formalities are out of the way, reconnaissance phase starts with a sole objective of information gathering. This intel (e.g, network layouts, domains, servers, infrastructure details) helps to understand how a network works including its assets (applications, systems, devices, anything with an IP).
This phase is performed with an aim of finding vulnerabilities within the defined targets. It involves scanning the target for listening services/open ports, fingerprinting and analysing the running services to prepare a rough attack layout of target systems.
Attempts are made to exploit common vulnerabilities to simulate and check how far a threat actor can go to achieve privileged access. For instance, during unauthenticated tests within a company network, many times starting with zero access leads to the entire network compromise. Default passwords or commonly used username/password combinations are also tried against various services.
Once access is gained to the systems, further efforts are undertaken to escalate privileges to the highest levels. This also includes hopping around the network in order to find vulnerable servers within the customer business. This technique, often known as lateral movement, helps to identify vulnerable systems within a network that is not exposed to the internet.
Specific assessments defined against certain targets are defined under ‘white box’, ‘black box’ or ‘grey box’ methodologies. These methodologies define test cases based on how much information is available to the consultants before starting the assessment.
No unsafe checks are carried out during the assessment. These include low level attacks such as ARP spoofing, SYN flood or the likes. Denial of service attacks are explicitly deemed out of scope.
Assessment phase is followed by data analysis and reporting phase. Cyphere performs analysis on the testing output, evaluates the risk impact and likelihood of exploitation in realistic scenarios before providing action plans to remediate the identified risks. All our reports address business as well as the technical audience with supporting raw data, including mitigation measures at strategic and tactical levels
Cyphere also provide a remediation consultancy where we help customers define and execute the risk mitigation plan. This is an optional service, and charged separately to penetration tests. A risk focussed approach is utilised to ensure a prioritized plan is followed to ensure maximum impact on increasing defensive controls.
Should you chose not to opt for this service, you can also take our help in preparing remediation plan and tasking your IT or managed services provider for implementation of controls.
Types of Penetration Testing

- Cloud Configuration Review
- Cloud Service Testing
- Cloud Security Testing
Cyber Attack Simulation
Cyber attack simulations are commonly designed with multi-step attack scenarios to check how defensive controls react during a real time attack. This includes red teaming (a simulation carried out to conduct a real life attack for assessing the attack preparedness) and blue/purple teaming (working in collaboration with your security teams to ensure it is a learning exercise to improve your detection). Cyber Attack Simulations will usually consist of:
- Red Team Assessment
- OSINT (Open Source Intelligence) Assessment
- Phishing Campaigns (Bulk, targeted/spear-phishing)
- Social Engineering
Mobile Penetration Testing
Mobile penetration testing will test your mobile applications before they go live, in order to reduce the chances of a data breach or other security vulnerabilities. If you have an insecure application, you could be compromising sensitive data or the device itself. Mobile Penetration Testing will usually consist of:
- Mobile Application Security Testing
- Secure Code Review

When to conduct Penetration Testing?
It’s safe to say there are a lot of different types of penetration testing, which is why it’s so important to speak with a cybersecurity professional to see what is the best fit for your needs.
From our knowledge and experience, a penetration test should be conducted at any of the following events:
- Introduction of new infrastructure & applications
- After major changes/upgrades
- Business As Usual/ Annual Assessments
- Before product/service go live
A business may be at risk if new services have been rushed into production without security assessment and mitigation of risks. This could leave an organisation open to cyber attacks. Therefore, it is important to measure the attack surface of underlying assets before releasing in production.
Some compliance requirements such as PCI, DSS, sector based commission technical audits, vendor assurance requirements, mandate regular penetration tests.
How much does a Penetration Test Cost?
For SME’s or organisations without security resources, we offer managed security services with multiple options to suit their requirements.
