Securing AIwith Intelligent Security
Defenx delivers AI security advisory and assurance through structured intelligence and expert-led analysis.
Our approach is grounded in practical experience across AI, cybersecurity, data, architecture and risk management.
Powered by the Trintel AI Security Intelligence Platform.
What we do
AI security advisory and assurance services
Defenx enables organisations to identify, prioritise and manage AI risk with clear visibility and controls.
We deliver practical, implementable controls that cybersecurity teams can apply across systems, vendors, and operational environments.
We support organisations adopting, building, or evaluating AI, including regulated enterprises, growing organisations, AI providers and delivery partners.
Our services are delivered using the Trintel AI Security Intelligence Platform, the proprietary Threat Triangle™ Framework, and Defenx methodologies, ensuring structured, repeatable and practical outcomes.
We do not deploy or operate controls within client environments and do not perform formal certification or independent audit services, ensuring objective and unbiased assessments.
Why AI Security
AI adoption is accelerating faster than organisations can control associated risks
Exposure now extends across systems, data and third-party integrations beyond the reach of traditional security controls.
These risks include adversarial manipulation, model and data integrity issues, third-party AI and supply chain exposure, and lack of visibility, ownership and oversight.
Without structured identification and governance, organisations lose visibility, increase dependency risk and expose operations to unreliable AI-generated outputs, adversarial manipulation and regulatory pressure.
AI Security Intelligence Platform
Trintel
Trintel is the Defenx AI Security Intelligence Platform. Trintel is designed to continuously ingest, analyse, and structure evolving AI threat intelligence and data-driven insights into actionable outcomes. Trintel combines external intelligence with organisational context to support risk-informed decision-making and control development.
Trintel is used internally by Defenx to deliver structured assessments and assurance artefacts, providing clear visibility of AI risk, prioritised risks, and enabling the development of practical controls to mitigate identified risks. These controls can be implemented across our customers’ cybersecurity, IT engineering, governance, assurance, and procurement functions.
Trintel addresses AI risk across the full AI system lifecycle. It ensures that risks are understood and managed in context, including data, models, pipelines, integrations, interactions and runtime environments.
Trintel is underpinned by the proprietary Threat Triangle™ Framework and Defenx methodologies, providing a structured approach to identifying and prioritising AI risk based on real-world impact and exposure. This enables organisations to focus on what matters most and implement appropriate controls.
Services
Expert Security Services
Defenx services are designed for cybersecurity teams and organisational stakeholders. This enables AI risks to be integrated into existing risk management, monitoring, vendor assurance, and incident response functions.
AI Security for Cybersecurity Teams
AI introduces risks across systems, data and third-party integrations that existing cybersecurity controls cannot fully see or manage. This creates blind spots, increasing dependency risk and makes it harder for teams to identify and prioritise what matters most in complex AI environments. Defenx supports cybersecurity teams with a structured, evidence-led approach based on real-world AI threat intelligence to identify AI usage, prioritise risks, and translate them into practical and implementable controls.
Enterprise AI Risk and Assurance Assessments
Structured assessment of AI systems, tools, data flows, integrations and third-party dependencies to identify and prioritise risks with clear ownership and accountability across the AI lifecycle. Includes evaluation of AI vendors, models, APIs and external services to identify supply chain, data exposure and dependency risks, supporting informed adoption, procurement decisions, and ongoing vendor risk management.
AI Governance, Risk & Architecture Advisory
Support for establishing governance structures, policies, roles, and oversight, and designing secure AI architectures, integrations, and control frameworks, ensuring visibility of data movement, trust boundaries, and exposure points, aligned to organisational risk management practices and regulatory expectations.
Implementation, Certification & Audit Readiness Support
Guidance during control implementation, including validation and assurance support, aligned with cybersecurity and operational environments, alongside support for alignment to ISO/IEC 42001 and NIST AI RMF, with structured documentation, traceability, and evidence artefacts for audit readiness.
