Agents Lie. RAG Leaks. And Other Truths from Production AI
Five hard truths from shipping a multi-agent SaaS platform on Azure: agents confidently contradict each other, RAG systems leak private data, and AI fundamentally changes your trust boundary.
Learn concrete patterns that stop your users from trusting hallucinations or finding their data in the wrong tenant.
Battling the Assumptions: How what you think you know about Azure Networking is a lie
Many teams approach Microsoft Azure networking with preconceived notions shaped by their experiences on-premises or in other cloud environments. These assumptions often lead to misconfigurations, security gaps, and scalability issues that are only discovered deep into production.
This session will break down the most common misconceptions about Azure networking and replace them with accurate mental models and practical strategies. Through real-world scenarios, architectural patterns, and clear explanations of Azure’s underlying networking constructs, attendees will gain the confidence to design and troubleshoot networks that truly align with Azure’s operational reality.
Point-in-time Security scans are a lie
Every compliance report, every Defender for Cloud scan, every Prowler run produces the same thing: a photograph of a moving target. You fix the findings, close the ticket, and three days later a misconfigured storage account slips through in a new deployment. Your posture was green. Your environment was not.
This session makes the case that point-in-time security assessments are structurally broken — and shows you what to build instead.
We'll walk through the architecture of a continuous security check engine covering 363 native Azure checks (Storage, Key Vault, Networking, Defender, AKS, Cosmos DB, and 30 more service domains), 299 Microsoft 365 checks mapped across CIS, SCUBA, EIDSCA, and Zero Trust frameworks, and 61 Zero Trust alignment checks matching Microsoft's own ZTA methodology. All of it running in the background, always, against your live environment.
No Prowler. No third-party agents. Just Azure Resource Graph, Microsoft Graph API, and 35 parallel collectors built natively in .NET.
You'll see the engine run live — scanning a real Azure tenant, surfacing real findings, and generating AI-powered remediation guidance on the spot.
You'll leave with:
- A mental model shift: posture as a continuous signal, not a periodic event
- The architecture for building your own native check engine
- The exact APIs, query patterns, and parallel execution model to get started
Devops is dead, Ai is coming for your job, and other nonsense...
Every six months, a new headline declares the death of something we all rely on and right now, DevOps and the engineers who practice it are squarely in the crosshairs. AI will write your pipelines, automate your deployments, and make your team of five redundant by Q3. Probably.
Except... no.
In this talk, we cut through the noise. We'll look at where AI is genuinely changing how we work and where the hype is doing more harm than good by sending teams chasing tools instead of solving problems. We'll talk about what "AI-assisted DevOps" actually looks like on the ground versus what it looks like in a vendor keynote. And we'll be honest about which parts of your job are actually at risk — spoiler: it's not the parts the headlines are worried about.
You'll leave with a clearer mental model for evaluating AI claims, a few patterns worth stealing, and the confidence to ignore the next wave of "everything is dead" takes — at least until the next conference season.
For: Platform engineers, DevOps practitioners, and anyone who's tired of being told their career is obsolete.
Not for: People who want to be told AI changes nothing and their workflow needs no rethinking.
Compliance in Business: Converting Regulations into Trust
Most teams treat compliance as a tax — a checklist you complete before launch so legal stops emailing you. GDPR. ISO 27001. The AI Act. SOC 2. Each one lands in the backlog with a groan and a budget request, and the output is a PDF nobody reads and a badge nobody notices.
But the companies pulling ahead aren't treating compliance that way.
This session makes the case that regulation, handled well, is one of the highest-leverage trust signals a business can send — to customers, to enterprise buyers, to the regulators themselves. We'll look at how to shift compliance from a reactive cost center to a proactive differentiator: what it takes to build it into your product and processes from the start, how to communicate it in ways that actually move deals, and where most teams waste effort on compliance theatre instead of compliance substance.
Concrete topics include: reading new regulations as product requirements rather than legal obligations, turning audit evidence into customer-facing transparency, and what "privacy by design" and "security by default" mean when you're shipping under real constraints.
You'll walk away with: a framework for evaluating which regulations are worth leaning into, a vocabulary for making the business case internally, and a clear picture of where compliance becomes a trust asset — and where it's just noise.
