London Office
Strategic London office for financial services, legal sector, and government clients. In-person executive briefings, scoping workshops, and sector-specific advisory, all backed by our CREST-accredited Leeds penetration testing team and Newcastle 24/7 SOC. UK data residency maintained throughout.
Financial Services, Legal,
Government.
London office specialises in the three sectors that dominate the capital. Our account team speaks the regulatory language of the City: FCA authorisation, DORA compliance, PCI DSS, and NCSC Cyber Assessment Framework. You don't need to translate your risk landscape for us.
Regulated Financial Sector
London office serves banking, insurance, asset management, and fintech clients requiring cyber security within FCA and PRA regulatory frameworks. Our account team understands DORA obligations for in-scope financial entities, PCI DSS penetration testing requirements for payment card environments, SWIFT CSP mandatory controls, and FCA PS21/3 operational resilience policy. Testing schedules align with change freeze windows, trading hours, and quarter-end processing cycles without disrupting critical financial operations.
City Law Firms & Chambers
Legal sector clients face unique security challenges: legal privilege, client confidentiality, SRA data protection requirements, and high-value M&A data targeted by nation-state actors. We deliver penetration testing and compliance assessments with appropriate confidentiality protocols for the sensitivity of legal environments.
Whitehall & NCSC Proximity
London location provides proximity to UK government departments in Westminster, NCSC Victoria headquarters, FCA offices, and ICO. Government and CNI engagements follow NCSC Cyber Assessment Framework guidance, GovAssure requirements, and CHECK assessment standards. All consultants are DBS-checked for government supply chain and sensitive sector projects.
Standards We Work Within
London clients operate under some of the most demanding regulatory frameworks in the UK. Our account team has worked across the full regulatory landscape, from FCA authorisation to government framework requirements, ensuring testing scopes, reporting formats, and compliance evidence align with what auditors and regulators expect to see.
Capital
Presence.
Face-to-face matters in financial services and government. Our London office provides professional meeting facilities for scoping workshops, executive briefings, and post-engagement debriefs, supported by a capital account team that understands your sector, your schedule, and your risk appetite.
Professional Meeting Environment

All meeting spaces operate under NDA as standard. Your commercially sensitive information does not leave the room.
Capital Account Team
London-based account managers coordinate all aspects of your engagement, from initial scoping through to report delivery and remediation support. Your account manager understands London business rhythms, capital client expectations, and sector-specific regulatory pressure. Direct line access, no call centres, no hand-off between sales and delivery.

Scoping & Planning Workshops
Detailed scoping workshops at our London meeting facilities where our technical consultants define assessment scope, identify critical systems, agree testing methodologies, and establish communication protocols. For financial services clients, we align testing windows with change freeze schedules, trading hours, and regulatory reporting timelines to minimise business disruption while maintaining CREST-accredited testing standards throughout.

Our London office provides strategic capital presence for client convenience. Many financial services, legal, and government clients are headquartered in London and prefer local meeting locations for executive briefings, scoping sessions, and debriefs. Maintaining a London office demonstrates commitment to capital clients while avoiding the operational inefficiencies of duplicating entire technical teams across locations. This model provides the best of both: convenient London client access plus specialist technical delivery from our CREST-accredited Leeds penetration testing team and Newcastle 24/7 SOC, all maintaining UK data residency.

Our London team has specialist experience across FCA authorisation requirements, DORA (Digital Operational Resilience Act) obligations for in-scope financial entities, PCI DSS penetration testing requirements for payment card environments, SWIFT Customer Security Programme mandatory controls, and FCA PS21/3 operational resilience policy requirements.
