**Building a World Model for your organisation in Microsoft Azure** In this session, Raj Toora will explore how organisations can build a “world model” of their business using Microsoft Azure. By combining knowledge graphs, ontologies, and modern AI tooling, firms can move beyond fragmented data into a connected, queryable representation of their operations. We’ll look at how technologies like Neo4j and Cypher enable rich relationship modelling, and how emerging Fabric capabilities around graphs and ontologies are bringing these concepts closer to mainstream data platforms. We’ll also examine how Azure AI Foundry and GraphRAG patterns can sit on top of this graph foundation, enabling LLMs to reason over structured relationships rather than isolated documents. This allows organisations to ground AI responses in real business context, improving accuracy and relevance. The session will demonstrate how combining vector search with graph traversal unlocks more intelligent, explainable AI experiences. Security and governance are critical in this space. Raj will cover how Open Policy Agent (OPA) can be used to enforce fine-grained access controls across graph data and AI workflows, alongside techniques such as data obfuscation and masking to mitigate data leakage and insider risk. These controls ensure sensitive information remains protected while still enabling meaningful analysis and AI-driven insights. Finally, we’ll bring this to life in a legal context. For law firms, a world model enables powerful new questions: “Find similar client,” “Analyse similar contracts” or “How are clients, cases, and outcomes connected?” By structuring knowledge in this way, firms can unlock institutional intelligence, accelerate case preparation, and gain a competitive edge through better-informed decision making. **About the Speaker** Raj Toora is the Principal Strategist for Emerging Technology for HSFK, a top international law firm, where he leads the translation of cutting-edge innovation into practical enterprise strategy and execution. He is responsible for shaping the firm’s direction across AI, data, and digital platforms, ensuring alignment with long-term business outcomes and its Target Operating Model. Raj works across architecture, security, operations, and practice leadership to turn emerging trends into actionable investment and delivery decisions, with a focus on scalable, sustainable transformation. His work centres on building systems of intelligence, advancing AI platforms, and enabling data-driven decision making that improves both client value and organisational performance.

## Details Welcome to the DevSecOps London Gathering April Event on Wednesday 29 April! We bring you two speakers, as well as the usual conversations, pizza and beer! 📍 **Hosted at Civo Tech Junction, 1st Floor, 32-37 Cowper Street, London, EC2A 4AW** 📅 **Wednesday, 29 April** 🕕 **6:00–8:00 PM** ## **Talk** **Abstracts:** **Talk 1** APIs are the hidden infrastructure that connects everything, like the plumbing of the modern age – though much like plumbing, **you don't realise you've got a problem until it’s too late**… This is doubly true for the AI era. It doesn't matter if you're orchestrating agents through OpenClaw, Warcraft 3 or MCP – **APIs remain the way AI escapes the bounds of the chat box into the real world**. But this new modality of APIs unfortunately didn't ship with more security. We’ve spent years lumping APIs into “web security” and calling it a day. As AI adoption accelerates, **API abuse is becoming the easiest way to escalate impact**: broken object-level auth, excessive data exposure, workflow manipulation, and agent overreach. **So what actually matters and how are attackers exploiting it?** Join **Dr Katie Paxton-Fear** as we explore API hacking as its own discipline, in the AI era. No generic web security theory. Instead, you’ll walk away understanding: * What makes **APIs uniquely vulnerable** * The bugs attackers **actually look for** * How **AI-driven workflows** expand impact * How to **test your own APIs effectively** **Katie's bio** Dr Katie Paxton-Fear is a hacker and security advocate at Semgrep – she used to make applications, and now she breaks them. A former developer, she sees security vulnerabilities as small mistakes by overstressed developers, and wants to find ways to make their life easier while making sure that we are all secure. She's found vulnerabilities in everything from the military to AI, in her own words 'without really knowing what I was doing'. She is passionate about giving back to the security community, delivering security training, writing and sharing her security research, and also through her YouTube channel – where she teaches almost 100,000 subscribers how to follow in her footsteps! She combines easy-to-understand explanations with key technical details, turning security into something everyone can understand and engage with. She's been featured as an expert in the Wall Street Journal, BBC News, ZDNet, The Daily Swig, Vodafone and more. **Talk 2** APIs are the hidden infrastructure powering modern cloud systems connecting services, platforms, and now increasingly, AI agents. In the AI era, APIs are no longer just consumed by users, they're being called, chained, and orchestrated by autonomous systems at scale. Whether it's agent workflows, microservices, or cloud-native platforms, APIs are the bridge between intelligent systems and real-world actions. However, while adoption has accelerated, security has not kept pace. Many organisations still treat API security as an extension of traditional web security, overlooking critical gaps introduced through architecture, identity design, and DevSecOps practices. So where are things actually going wrong? Join me to explore how modern cloud architectures unintentionally expose APIs from misconfigured gateways and over-permissioned identities to weak trust boundaries across services. The session will also examine how AI-driven workflows amplify these risks, turning small design flaws into large-scale vulnerabilities. **Sriram's Bio** Sriram Kumar is a Solution Designer with multiple years of experience in cloud and DevOps engineering, specialising in Microsoft Azure. He has a strong background in designing and securing cloud-native architectures, including API Management, identity-driven access, and enterprise-scale infrastructure. Sriram has worked across multiple organisations delivering secure, scalable solutions, with hands-on experience in Cloud networking, CI/CD pipelines, and DevSecOps practices. His work often involves solving real-world challenges around API security, cloud governance, and system resilience in complex environments. Beyond his professional work, Sriram actively contributes to the community through NGO initiatives and mentoring students, supporting them in building careers in cloud and technology. With a practical, architecture-first approach, Sriram focuses on bridging the gap between development, operations, and security, helping teams build systems that are not only functional but secure by design.
