The Vulnerabilities in Your Systems
Exist Whether You Test for Them or Not.
A penetration test answers the question every security programme eventually has to face: not whether vulnerabilities exist, but which ones are exploitable, how consequential their exploitation would be, and what needs to change before someone with the wrong intentions finds them first. We conduct penetration tests that find what automated scanners miss, explain what findings mean in the context of your business, and support the remediation that follows.
"$4.88 Million" — the average cost of a data breach in 2024. The majority involve vulnerabilities that existed long before the incident and that targeted testing would have found. (IBM Cost of a Data Breach Report)
Knowing You Have Vulnerabilities Is Not the Same as Knowing Which Ones Matter.
Automated scanning finds known signatures efficiently. It does not find the vulnerability that exists because of how your specific application was built, your specific network was configured, or your specific systems were combined.
Your automated scans are giving you a false sense of coverage
Vulnerability scanners compare your systems against databases of known issues. They are fast and useful for a specific purpose. They do not simulate an attacker — they do not chain vulnerabilities together, explore business logic flaws, test for the issues that arise from the specific combination of your systems and configurations, or find the vulnerabilities that no signature has yet been written for. An organisation that relies on scanning alone has an incomplete picture of its actual exposure.
You cannot prioritise remediation without understanding real-world impact
A critical CVSS score describes the theoretical severity of a vulnerability class. It does not describe what an attacker could actually achieve by exploiting that specific vulnerability in your specific environment. Without the context that exploitation provides — what systems were reached, what data was accessible, what lateral movement was possible — remediation efforts are prioritised against theoretical risk rather than demonstrated impact.
Compliance requires it, but compliance alone is not sufficient reason to do it
SOC 2, PCI DSS, ISO 27001, and most enterprise security requirements include penetration testing. The testing conducted to satisfy these requirements varies enormously in quality — from a thorough manual assessment that finds things that matter to an automated scan renamed as a penetration test on the report cover. The requirement gets met. The security posture may not improve meaningfully. The distinction matters most when the incident happens.
Your attack surface is larger and more complex than your last assessment covered
New features shipped, new APIs exposed, new third-party integrations added, new cloud infrastructure deployed — every change to your environment is a potential change to your attack surface. An assessment conducted twelve months ago against a system that has since changed significantly tells you what was exploitable then. It does not tell you what is exploitable now.
Penetration Testing Conducted by People Who Think Like Attackers and Report Like Advisors
We conduct penetration tests — against web applications, APIs, internal networks, external infrastructure, mobile applications, cloud environments, and the people in your organisation — with the depth and creativity that manual testing by experienced practitioners makes possible. We simulate the techniques used by real threat actors against the specific systems and configurations of your environment. Every finding is documented with the technical evidence of exploitation, the realistic business impact of what was accessible, and the specific remediation that closes the gap — written to be acted on, not filed.
The Threat Landscape Looks Different Depending on What You Are Protecting
The attack vectors most relevant to a fintech application are different from those most relevant to a healthcare platform, a manufacturing operation, or a law firm. The data at risk differs. The threat actors most likely to be interested differ. The regulatory and contractual requirements for testing differ. We bring that contextual understanding to every engagement — so the testing we conduct focuses on the threats and techniques most relevant to your specific environment and what it contains.
Financial Services & Fintech
Where the applications and infrastructure handling payment data, account credentials, and financial records are among the most targeted in any sector — and where the consequences of a successful breach extend from customer harm to regulatory sanction.
Healthcare & Digital Health
Where the sensitivity of the data processed, the regulatory obligations of HIPAA and its equivalents, and the real-world consequences of compromised patient systems make rigorous, regular penetration testing a genuine operational necessity.
SaaS & Technology
Where the application is the product, the API is the attack surface, and a security failure is simultaneously a technical incident, a customer trust crisis, and a competitive event — often compressing into the same news cycle.
Retail & E-commerce
Where payment processing environments, customer account systems, and administrative interfaces face continuous automated attack attempts and where PCI DSS requires annual penetration testing of the cardholder data environment.
Legal & Professional Services
Where client confidentiality obligations, matter data, and financial information sit in systems that are rarely as well-tested as the sensitivity of what they contain warrants — and where the reputational consequence of a breach is often more damaging than the financial one.
Government & Public Sector
Where the attack surface is publicly known, the threat actor landscape includes nation-state actors, and the accountability for failures is both regulatory and public — making thorough, regular offensive testing a security baseline rather than an optional programme.
Manufacturing & Critical Infrastructure
Where the convergence of IT and operational technology creates an attack surface with physical consequence, and where the testing of OT-adjacent systems requires the care and specificity that the environments in question demand.
Education
Where student records, research data, and financial information sit in systems that are widely accessible, often under-resourced for security, and increasingly targeted by ransomware operators who have recognised the sector's combination of valuable data and security immaturity.
Deep Technical Expertise
What we build, integrated seamlessly into your existing operations.
Web Application Penetration Testing
Manual assessment of your web applications — authentication mechanisms, session management, access control logic, input validation, business logic, and the application-specific vulnerabilities that automated scanning cannot find — conducted by testers who understand how applications are built and how attackers approach them.
API Security Testing
Targeted assessment of your API layer — REST, GraphQL, SOAP, and gRPC — for authentication weaknesses, broken object and function-level authorisation, data over-exposure, rate limiting failures, injection vulnerabilities, and the business logic flaws specific to how your APIs are designed and consumed.
Network Penetration Testing
Simulated attack against your internal or external network infrastructure — identifying exposed services, misconfigured systems, unpatched vulnerabilities, weak credentials, and the lateral movement paths that would allow an attacker to progress from initial access to their objective.
External Infrastructure Testing
Assessment of your externally facing attack surface — the systems, services, and entry points visible from the internet — approached from the same vantage point as an external attacker with no prior knowledge of your environment.
Internal Network Testing
Simulation of an attacker who has gained a foothold inside your network — through a phishing success, a compromised VPN credential, or physical access — exploring the lateral movement, privilege escalation, and data access paths available from an internal position.
Mobile Application Testing
Assessment of your iOS and Android applications — data storage security, network communication, authentication implementation, binary protections, reverse engineering exposure, and the API contracts the application depends on — using the techniques mobile-focused threat actors actually employ.
Cloud Infrastructure Testing
Security assessment of your cloud environment — IAM misconfigurations, storage permissions, network controls, metadata service exposure, secrets in code and environment variables, and the cloud-specific attack paths that differ significantly from on-premises testing approaches.
Social Engineering & Phishing Simulation
Controlled simulation of the phishing, vishing, and pretexting techniques used in the majority of successful real-world attacks — testing your organisation's detection capability, employee response, and the technical controls that either limit or amplify the impact of a successful deception.
Wireless Network Testing
Assessment of your wireless infrastructure — encryption configuration, authentication mechanisms, rogue access point detection, client isolation, and the attack paths available from wireless access — for corporate, guest, and IoT network segments.
Red Team Exercises
Objective-based adversary simulation — a sustained, multi-vector engagement designed to test your organisation's detection and response capability as well as its technical defences, conducted without the knowledge of your security operations team to produce a realistic measure of your resilience.
Source Code Review
Expert review of your application source code for security vulnerabilities — authentication flaws, injection risks, cryptographic weaknesses, insecure data handling, and the logic errors that automated static analysis tools find the pattern of but not the impact of.
Remediation Verification Testing
Targeted retesting of vulnerabilities identified in a previous assessment to confirm that the fixes applied are effective — that the vulnerability is genuinely closed, completely, without introducing new issues in adjacent code or configuration.
From Scoping What We Test to Confirming That What We Found Has Been Fixed
The value of a penetration test is determined by three things: the depth of the testing conducted, the clarity of the findings reported, and the rigour of the verification that remediation was effective. We invest in all three — because a test that finds things but produces findings no one acts on has not improved your security posture.
Scoping the Engagement With Precision
We define the scope with you — which systems, which components, which user roles, which testing techniques, which threat scenarios — and explain the reasoning behind every boundary. You should understand exactly what is being tested, what is not, and why those boundaries were drawn where they are. Scope ambiguity produces scope disputes during the engagement. We eliminate it before testing begins.
Conducting Reconnaissance and Mapping the Attack Surface
Before active exploitation attempts begin, we map the attack surface — identifying the entry points, the technologies, the user roles, the data flows, and the specific characteristics of your environment that will shape how we approach the testing. Reconnaissance conducted properly produces a more focused and more effective assessment than testing conducted without it.
Testing With the Depth the Scope Demands
We conduct the assessment — combining automated tooling with manual testing techniques, attempting to exploit the vulnerabilities found, chaining weaknesses where the combination is more significant than any individual finding, and pursuing the specific business logic and application-layer issues that require a human understanding of how your system works to find. Every technique used is documented. Every finding is supported by evidence of exploitation.
Reporting Findings for Two Audiences
We report every finding with technical detail sufficient for the developer or engineer who needs to fix it, and impact context sufficient for the leadership who needs to understand the risk and allocate remediation resources. Neither audience should have to translate the report for the other. Critical findings that require immediate attention are communicated before the report is finalised — not discovered in it.
Supporting Remediation and Verifying That Fixes Work
We remain engaged through remediation — answering technical questions, reviewing proposed fixes before they are implemented, and flagging when a fix addresses the symptom rather than the root cause. When remediation is complete, we retest — because the only meaningful measure of a vulnerability being fixed is a test that confirms it can no longer be exploited.
Who This Works Best For
Penetration testing creates the most meaningful value in specific conditions. We would rather help you understand what kind of testing your situation calls for than propose an engagement that doesn't fit your environment, your maturity, or your immediate security priorities.
You have systems in production that handle sensitive data or support business-critical functions
The more consequential the impact of a successful attack on your systems, the more valuable it is to understand the real exploitability of the vulnerabilities they contain — before an attacker does. Production systems handling customer data, payment information, health records, or business-critical operations are the clearest candidates for rigorous penetration testing.
You are approaching a compliance requirement, a significant release, or enterprise due diligence
PCI DSS requires annual penetration testing of the cardholder data environment. SOC 2, ISO 27001, and HIPAA assessments frequently require evidence of penetration testing. Enterprise customers conduct security reviews that include testing evidence. These moments create the forcing function for testing that should ideally be more continuous — and we can help you prepare for them with the depth that external reviewers will scrutinise.
Your application or infrastructure has changed significantly since your last assessment
A penetration test is a snapshot of your security posture at the time it is conducted. Every significant change to your environment — new features, new APIs, new infrastructure, new integrations — is a potential change to your attack surface. If your systems have evolved substantially since your last assessment, what was tested is no longer what you have.
You want to understand whether your security controls actually work under real attack conditions
Documented controls, configured tools, and defined processes are the intended state. A penetration test — particularly a red team exercise — tests whether the intended state is the actual state: whether the controls detect what they are configured to detect, whether the response processes activate as designed, and whether the assumed protections hold under deliberate, creative adversarial pressure.
And when a different starting point might serve you better
If your application is still in early development with significant architectural changes ahead, threat modelling and secure design review will produce more durable value than penetration testing — you cannot usefully test the final security posture of a system that is still being designed. If your primary concern is knowing which known vulnerabilities exist across a large asset inventory, a vulnerability assessment may be the more proportionate tool for that specific question. If your team does not yet have the capacity to act on penetration testing findings in a reasonable timeframe, the investment in testing is partially wasted until that capacity exists. We will tell you clearly when a different scope, type, or sequence of work would serve you better.
Findings That Are Specific, Prioritised, and Built to Be Acted On
Every penetration test we conduct produces documentation designed to drive remediation — not to demonstrate the volume of the work performed or to justify the engagement fee. Here is what every engagement delivers.
A detailed technical findings report
Every vulnerability documented with the specific steps taken to discover and exploit it, the evidence of successful exploitation, an honest assessment of the real-world impact in your specific environment, and a prioritised, specific remediation recommendation — written for the developer or engineer who needs to fix it.
An executive summary for leadership
A clear, jargon-free summary of the overall security posture, the most significant findings, the realistic business risk they represent, and the recommended remediation priorities — written for the leadership audience who needs to understand the risk and allocate resources, without needing a technical background to do so.
Exploitation evidence and proof-of-concept documentation
Where exploitation was successful, the evidence — screenshots, captured data samples, session tokens, access logs — that demonstrates what was accessible and what an attacker in the same position could have done. Impact claims are supported by evidence, not asserted.
Remediation support through the fix process
Availability to answer technical questions, review proposed fixes before implementation, and flag when a remediation addresses the symptom rather than the underlying vulnerability — so the effort your team puts into fixing findings is directed correctly.
Verification testing on remediated findings
Retesting of every critical and high finding after remediation to confirm the fix is effective and complete. The engagement is not closed until we have confirmed that what was found can no longer be exploited in the way it was during the assessment.
The Kinds of Problems We Are Built For
Every organisation that comes to us arrives with something specific. Here are the situations where penetration testing has found what needed to be found — before someone else did.
Fintech
A fintech company processing payments for SMEs was approaching its annual PCI DSS assessment and wanted confidence in the security of its payment processing environment before the QSA arrived. We conducted a web application penetration test focused on the cardholder data environment and found a broken function-level authorisation vulnerability in their administrative API that allowed any authenticated merchant user to access the transaction records of any other merchant on the platform. The finding was critical — it represented exposure of cardholder data at scale. The vulnerability was remediated and verified before the QSA assessment began. The QSA cited the quality of the pre-assessment testing as a positive indicator of the organisation's security programme maturity.
Healthcare
A digital health platform handling patient appointment data and clinical correspondence was conducting its first formal penetration test ahead of an NHS trust partnership. Their previous security review had been an automated vulnerability scan that produced a clean report. We conducted a manual web application and API assessment and found, within the first day of testing, an insecure direct object reference vulnerability that allowed any authenticated patient user to access the appointment records and clinical notes of any other patient on the platform by manipulating a single parameter. The finding had existed since the original application build. It was found, reported, remediated, and verified before the partnership assessment. The trust's security review proceeded without the finding surfacing.
SaaS & Technology
A B2B SaaS company had received a security questionnaire from a prospective enterprise customer requiring evidence of annual penetration testing — testing they had never formally conducted. We performed a web application and API penetration test, found eight vulnerabilities including two high-severity issues in their authentication flow and one server-side request forgery vulnerability in a document processing feature. We supported full remediation and provided the testing report and remediation evidence the customer's security team required. The deal progressed. The security programme the test initiated became a quarterly cadence.
Retail
A retail brand had expanded its e-commerce operation significantly over the previous eighteen months, adding a mobile app, a new checkout flow, and a loyalty programme — none of which had been security tested. We conducted a combined web application, API, and mobile application assessment covering all three additions. The most significant finding was a mass assignment vulnerability in the loyalty programme API that allowed any authenticated user to arbitrarily modify their own loyalty points balance. Secondary findings included session fixation in the new checkout flow and sensitive data exposure in the mobile app's local storage. All findings were remediated within six weeks of report delivery.
Professional Services
A law firm had been notified by a client that their matter management portal — through which the client uploaded confidential documents and communicated with their legal team — had been flagged in an external security scan as potentially vulnerable. We conducted an application penetration test focused on the portal and found a path traversal vulnerability in the document download function that allowed authenticated users to access files outside their permitted directory — including documents belonging to other clients of the firm. The finding was escalated immediately on discovery, remediated within 48 hours with our technical support, and verified the following day. The client relationship was preserved. The firm subsequently established annual penetration testing of all client-facing systems.
The Immediate and Lasting Value
Vulnerabilities found by the people you hired, not the people you didn't
Every vulnerability we find is one that an attacker did not find first. The cost of a penetration test is fixed and known. The cost of the breach it prevents is neither.
Real exploitability, not theoretical severity
We tell you which vulnerabilities in your specific environment are actually exploitable, what an attacker could access or accomplish through them, and how that maps to the business risk your organisation actually carries — not what a CVSS score implies about the vulnerability class in the abstract.
Findings that development teams can act on
A finding documented with specific reproduction steps, exploitation evidence, and a precise remediation recommendation gets fixed. A finding documented as a vulnerability category reference number does not. We write for the people doing the remediation — because reports that don't get acted on have not improved anything.
Security knowledge that transfers to your team
We explain what we found, why the vulnerability exists, and what patterns of code or configuration produce it — so your developers understand not just how to fix this finding but how to avoid the same class of vulnerability in the code they write next.
Compliance evidence that reflects actual testing quality
Penetration testing reports produced by manual assessment by experienced practitioners carry significantly more weight in compliance reviews, enterprise due diligence, and regulatory discussions than automated scan reports renamed as penetration tests. The distinction is visible to the people reviewing the evidence — and it matters.
Confidence that is grounded in evidence, not assumption
The difference between believing your systems are secure and having tested whether they are is the difference between an assumption and a finding. Penetration testing replaces the first with the second — and the clarity that produces is valuable regardless of what the testing finds.
What Changes When You Test Before an Attacker Does
These are the kinds of outcomes our clients experience — not as projections, but as the natural result of conducting penetration testing with genuine depth, honest reporting, and a commitment to findings that actually get resolved.

Trusted With Access to Find Vulnerabilities. Accountable for Every Action Taken.
Penetration testing requires us to attempt to compromise your systems — to exploit vulnerabilities, access data, and demonstrate impact in ways that are, by definition, adversarial. We take the responsibilities that come with that mandate with the seriousness they demand.
We operate strictly within agreed scope and rules of engagement
Every technique applied, every system accessed, and every exploitation attempt conducted during an engagement is within the scope and rules of engagement agreed in writing before testing begins. We do not test systems not explicitly in scope. We do not use techniques not explicitly permitted. We do not exceed the access boundaries defined for the engagement. The authorisation granted to us is treated as the limit of what we do — not a starting point for improvisation.
We escalate critical findings immediately, not at report delivery
When we find a vulnerability that represents an active, critical risk — credentials exposed, data accessible without authentication, a zero-day in a production system — we communicate that finding to you immediately. We do not hold critical risk information until the scheduled report delivery date. The purpose of penetration testing is to improve your security posture. That purpose is not served by allowing a critical finding to remain unaddressed while we continue testing.
We access only what is necessary to demonstrate impact
When we gain access to data through a vulnerability, we access and document what is necessary to demonstrate the impact of the finding — and no more. We do not exfiltrate sensitive data beyond what a proof of concept requires. We do not retain data accessed during testing. We do not use access obtained during a test for any purpose beyond the documentation of the finding it was obtained to demonstrate.
We tell you what we found, at the severity it merits, without softening
A penetration test that downplays critical findings to preserve a relationship, that frames severe vulnerabilities as medium severity to avoid difficult conversations, or that omits findings because they reflect poorly on a previous assessment has not served its client. We report honestly — the finding, the exploitation evidence, the realistic impact, and the severity it merits. If that is uncomfortable, the discomfort serves your security. Comfortable reports that don't change anything do not.
The Values Behind Every Penetration Test We Conduct
Manual depth is not optional — it is the point
Automated scanning is fast and useful for finding known issues at scale. It is not a penetration test. The findings that matter most — the business logic flaws, the chained vulnerabilities, the application-specific issues that arise from how your system was built — require a person who understands what they are looking at, how attackers think, and how to pursue a finding beyond the initial detection. We conduct manual penetration testing by experienced practitioners because that is the only kind that finds what needs to be found.
Impact is the unit of measurement, not findings volume
A penetration test that produces forty medium-severity findings and misses the authentication bypass that would have given an attacker full access to your user database has not served you well — regardless of the length of the report. We focus our effort on the findings that carry real impact in your specific environment and for your specific threat landscape. We would rather find three things that matter than thirty things that don't, and we are honest when the testing suggests your security posture is stronger than your concerns implied.
The report is written to be used, not to demonstrate effort
Penetration test reports fail their purpose when they are written for the auditor filing them rather than the developer fixing them or the leader resourcing the remediation. We write for both audiences — technical detail for the people doing the work, impact context for the people making the decisions — and we measure the quality of a report by whether it produces the remediation it describes, not by its page count.
The engagement does not end when the report is delivered
A finding documented and unresolved has not improved your security posture. We remain engaged through the remediation process — answering questions, reviewing fixes, and retesting — because the value of penetration testing is in the vulnerabilities that get closed, not the vulnerabilities that get documented. The organisations whose security improves most from testing are those who treat the report as the beginning of the work rather than the end of the engagement.
