Penetration Testing

Penetration Testing Services

Find the weaknesses in your environment before someone with bad intentions does.

Every organisation has vulnerabilities. Many are invisible to the human eye, but can be exploited through tools and techniques. These could have a major impact on your organisation. The question is whether you find them first or an attacker.

Penetration testing is the controlled, ethical way of finding these first, with a qualified tester using similar tools and techniques as an attacker, against your systems, with your explicit permission. The goal is to identify findings and enable you to remediate based on your risk appetite, before they are exploited by a bad actor.

RB Consultancy Ltd partner to provide penetration testing services for infrastructure, web applications and cloud environments. More specialised testing can also include APIs, mobile applications, social engineering, PCI-DSS environments and AI/LLM systems.

All testing is carried out by highly experienced and certified practitioners. They deliver findings through continuous collaboration and real-world context, producing actionable outputs, because a report that sits in a drawer won’t help your business.

Why Do Organisations Need Cyber Essentials?

Three reasons certification is becoming non-negotiable for organisations of all sizes.

Internal and External Infrastructure

Testing your environment from two positions: the internet (simulating an opportunistic attacker) and from inside your network (simulating an attacker who already has a foothold).

The external test shows what an attacker could access from outside; the internal test shows what they could do once inside. Most organisations benefit from seeing both perspectives.

Web Application Testing

Experts identifying security flaws in your websites and applications: authentication weaknesses, logic flaws, code vulnerabilities. Findings help you understand the risks and create action plans to safeguard your users, customers and organisational data.

Cloud Security Assessment

Assessments on AWS, Azure and Microsoft 365, identifying misconfigurations, insecure settings, MFA and access policy weaknesses. Cloud misconfiguration is one of the most consistently reported sources of breach in UK organisations and is often invisible to internal teams.

Active cloud penetration testing can also be arranged for organisations needing a more adversarial assessment.

Additional Services

Call us to discuss more niche services including APIs, mobile applications, social engineering, PCI-DSS environments and AI/LLM systems.

Annual test due?

Most pen tests are scoped 4–8 weeks ahead.

If you have an audit, contract renewal or insurance requirement coming up, it pays to get the scoping conversation in early.

What's included

Every engagement is scoped,
certified and actionable

Three commitments that apply to every penetration testing engagement we deliver.

Before any testing begins, the scope, methodology and reporting is discussed. This protects all parties and ensures the testing produces results relevant to your risk profile. Nothing is tested without explicit authorisation.

02

Certified practitioners

You get proven experience, real-world insight and professionalism, working alongside you to give you confidence and security.

03

Common Questions

Frequently Asked Questions

Quick answers to the questions we get most often. Anything else, ask us.

A vulnerability scan uses automated tools to identify known weaknesses in systems and software — to produce a list. Our penetration test services use qualified human assessor(s) to actively attempt to exploit vulnerabilities, chain them together and understand what an attacker could realistically achieve. The outputs are different — with a vulnerability scan telling you what exists and a penetration test telling you what an attacker could do with it and how serious that could be.

Annual testing is the minimum baseline for most engagements. Additional testing is recommended linked to significant change — such as major software updates, projects and new systems. Your supplier, insurer or contracts may specify a required frequency — it is definitely worth checking what they say, rather than assuming.

Testing is carried out within agreed parameters, designed to minimise any risk of disruption. We discuss timing and approach during scoping. Penetration testing can involve assessment and active exploitation however, so there is always an element of risk. Call us to discuss this and we agree what the scope is and how best to prepare, before the testing begins.

No. Cyber Essentials Plus includes a structured vulnerability assessment as part of its technical audit, specifically checking for weaknesses related to the five technical controls of Cyber Essentials. A penetration test goes deeper — as well as looking for weakness, testing techniques are used to show how the weaknesses can be exploited and the likely impact. Many organisations want both aspects — a clean vulnerability assessment for Cyber Essentials Plus certification and periodic penetration testing for their infrastructure, applications and cloud services.
