CREST-Accredited Penetration Testing Services

Helping you uncover vulnerabilities, strengthen your security posture, and obtain the cybersecurity assurances your organisation needs.

What is Penetration Testing?

An In-Depth, Expert-Led Investigation

Penetration testing, often referred to as pen testing or ethical hacking, is a structured security assessment in which certified consultants attempt to identify and exploit vulnerabilities in your systems, applications, or infrastructure. Unlike automated vulnerability scanning, penetration testing involves active human analysis: our consultants think like real attackers, chaining together weaknesses and exploring attack paths that automated tools simply cannot replicate.

A penetration test can be targeted at a specific system, such as a web application or internal network, or scoped more broadly to cover your entire external attack surface. Tests are typically conducted under one of three conditions: black box (no prior knowledge of the target), grey box (partial knowledge, simulating a partially informed attacker), or white box (full knowledge, designed to be the most thorough assessment possible).

The output is a detailed report covering every vulnerability identified, its risk rating, the evidence gathered, and clear remediation guidance, written for both your technical teams and your board.

Our CREST-accredited penetration testing services are designed to:

Uncover vulnerabilities

Our consultants will identify as many vulnerabilities as possible within the agreed scope and timeframe, manually going beyond surface-level findings to explore complex, chained attack paths & routes that pose genuine risk to your organisation.

Verify potential risks

Every vulnerability we identify is manually verified to confirm it is genuine and exploitable. We assess each finding in the context of your environment and business, so you understand not just what is vulnerable, but what the real-world impact of exploitation would be.

Improve your security

Our engagement doesn't end with report delivery. Our consultants are available post-test to walk your team through findings, answer technical questions, and support you through the remediation process, helping you close vulnerabilities effectively, not just tick a box.

Provide assurances

Whether you need assurance for internal stakeholders, clients, regulators, or your board, our penetration testing services provide the documented evidence that the systems and environments under review have been rigorously tested by accredited professionals.

Our Penetration Testing Services

Penetration testing is not a one-size-fits-all discipline. Our services are tailored to the specific environment under review, the threats most relevant to your organisation, and your cybersecurity priorities. Every engagement is scoped individually and delivered by directly employed, certified consultants.

Web Application Penetration Testing

Web applications are one of the most commonly targeted entry points for attackers. Our web application penetration testing service provides in-depth security testing of your websites, APIs and web-based platforms, covering the OWASP Top 10 and beyond, including business logic flaws, authentication weaknesses, and session management vulnerabilities.

Web Application Testing >

Mobile Application Penetration Testing

Mobile applications introduce a distinct set of security risks, from insecure data storage and weak authentication to unprotected API backends and inter-app communication vulnerabilities. We test both iOS and Android applications using static and dynamic analysis techniques, providing a thorough assessment of your mobile attack surface.

Mobile Application Testing >

Infrastructure Penetration Testing

Internal and external network infrastructure remains a primary target for threat actors, whether opportunistic attackers scanning for exposed services or sophisticated adversaries seeking to escalate privileges and move laterally. Our infrastructure penetration testing covers both external perimeter testing and internal network assessments, identifying misconfigurations, unpatched vulnerabilities, and privilege escalation paths before attackers do.

Infrastructure Testing >

Cloud Penetration Testing

Cloud environments introduce unique security challenges around identity and access management, storage configuration, and cloud-native attack paths that traditional network testing doesn't address. Our cloud penetration testing services assess the security of your AWS, Azure, Oracle and GCP environments, identifying misconfigured services, over-privileged accounts, and exposed resources that could be exploited by an attacker.

Cloud Service Testing >

IoT/Embedded Device Penetration Testing

Connected devices and embedded systems present significant security risks, particularly where sensitive data is processed or where compromise could have operational or physical consequences. Our IoT and embedded device penetration testing covers hardware analysis, firmware review, communication protocol testing, and device-level vulnerability assessment.

The Pentest Approach

Our Approach to Penetration Testing

The assurance we provide doesn’t come from a standardised process applied uniformly to every client. It comes from over 25 years of experience, a methodology refined across thousands of engagements, and a team that takes the time to understand your environment before testing it.

Understanding Your Requirments

No two organisations are the same. Before any testing begins, we work closely with you to understand your environment, your priorities, and the specific risks you need to address. This allows us to put forward a bespoke proposal of work that is scoped to deliver maximum value, rather than a fixed-price template applied without context.

Expert-Led, Manual Testing

Every engagement is conducted manually by our certified security consultants, all of whom are directly employed by Pentest. We do not use subcontractors or offshore resource. Our consultants bring deep technical expertise and an attacker's mindset to every test, going beyond what automated tooling alone can surface to identify the vulnerabilities that pose genuine risk to your organisation.

Clear, Actionable Reporting

Our reports are written for two audiences: the technical teams who need to act on findings, and the executives who need to understand business risk. Every report includes an executive summary, a full technical breakdown of all identified vulnerabilities with risk ratings and evidence, and prioritised remediation guidance that tells you what to fix first and why.

Post-Test Support & Remediation Assistance

Our consultants are available after testing to walk your team through findings, answer technical questions, and support you through the remediation process. We can also provide fix verification checks to confirm that vulnerabilities have been correctly resolved, along with any additional documentation required for compliance or governance purposes.
