Security Testing for Complex Platforms, Products & Infrastructure
We support UK and international organisations with complex platforms, products, and infrastructure to understand real-world risk, maintain compliance, and pass critical audits. Our penetration testing engagements are regularly used to support: ISO 27001 certification and surveillance audits, SOC 2 readiness and attestation, DORA and regulatory assurance requirements, Cyber Essentials Plus, investor due diligence, and internal board reviews. We work across industries — wherever systems are complex, security matters, and assurance is required.

What Our Penetration Testing Actually Delivers
We are a small, close-knit and highly experienced team of Senior Pentesters and Technical Programme Managers. We guarantee experienced penetration testers with deep SaaS, infrastructure and operational platform expertise. We have practical understanding of audit expectations and deliverables, and deliver independent and manual-led pentests with a quick and thorough turnaround. We assess how vulnerabilities can be exploited in practice, and tell you the realistic business impact of these, both individually and chained. We tell you where risk truly sits, specific to you — not just where scanners say it does. Every engagement concludes with a clear, defensible technical report, board-ready executive summary, practical remediation guidance and risk ratings aligned to business impact. We provide evidence suitable for auditors and assessors, keeping it relevant. No inflated findings. No fear-based language. No noise.

Evidence Over Noise
We report what we find and verify - clearly, accurately and without exaggeration. No inflated or fear-based language - just defensible, audit-ready security findings that you can get behind. Our reports are structured to support ISO 27001, SOC 2, Cyber Essentials Plus and other assurance frameworks.
Operationally Aware Pentesting
Security testing should support delivery and business continuity, not derail it. We work in step with your engineering, compliance and senior leadership teams, balancing risk, business reality and audit requirements.
Senior-Led Accountability, Always
Every engagement is delivered by highly experienced, qualified penetration testers and a Technical PM — not junior staff or outsourced contractors. You get consistent quality, direct communication, and accountability from start to finish.
Working Alongside Your Team
We regularly collaborate with ISO 27001 and SOC 2 consultants, internal compliance and risk teams, fractional and in-house CISO/CTOs, Leadership and Founders. We integrate cleanly into existing workflows, reporting structures, and timelines — operating as a senior extension of your internal team. You won’t need to chase us. You won’t need to translate our findings. You won’t need to manage the process. We understand what auditors require, what technical teams need, and what leadership expects — and we deliver.

Compliance is not the only goal. Resilience is. Our testing directly supports risk registers, remediation planning and validation, ongoing security maturity and continuous improvement cycles. We design engagements so the output is usable — not just presentable.

Our Pentest Reports contain extensive details of the vulnerabilities identified throughout our engagement. This example report gives an idea of what information you can expect to find and how we present our findings to both your technical and non-technical stakeholders.
