From Passwords to Passkeys: Enterprise Identity Architecture, FIDO2/WebAuthn Migration, and Phishing-Resistant MFA at Scale Enterprises are moving beyond passwords, OTPs, and push approvals toward phishing-resistant multi-factor authentication built on passkeys and the FIDO2/WebAuthn standards. The shift is more than swapping one factor for another; it reshapes identity architecture, user experience, device trust, and the security […]

When the Internet Sneezes: How the Recent Cloudflare Outage Ripples Across U.S. Websites The recent Cloudflare outage was a reminder that modern websites in the United States share more infrastructure than many realize. What looked like “my favorite site is down” to everyday users was, in many cases, a systemic event—DNS lookups timing out, content […]

Policy-as-Code for AI Agents: Identity, Least-Privilege, and Auditability for Safe Enterprise Automation Enterprises are racing to deploy AI agents that read, write, and act across systems—triaging incidents, reconciling invoices, drafting agreements, or fetching data on demand. The leverage is enormous, but so is the blast radius if things go wrong: a prompt-injected agent can exfiltrate […]

Diagnosing and Fixing “OpenAI Error: OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 104” Few errors cause as much confusion as a TLS read failure that bubbles up from OpenSSL with “SSL_ERROR_SYSCALL” and Linux errno 104. When this pops up during an OpenAI API call—often in the middle of a streaming response—it can feel like the server suddenly “hung […]

Data Contracts Are the New APIs: Productizing Data for Reliable, Compliant Analytics and AI Why Data Contracts, Why Now Software teams would never ship a service without a clear API, versioning strategy, and uptime guarantees. Yet data teams routinely push breaking changes to tables, rely on best-effort refreshes, and leave consumers guessing what fields mean. […]

Zero ETL, Real-Time Enterprise: Direct Data Sharing That Simplifies Analytics, AI, and Compliance For decades, organizations have moved data from where it’s created to where it’s analyzed through extract-transform-load (ETL) pipelines. That model introduced delay, duplicated data, and accumulated governance risk. “Zero ETL” turns this on its head by making data available for analytics, AI, […]

Zero Trust for the Factory Floor: Securing OT/ICS Without Slowing Production Introduction: The Factory Floor Paradox Manufacturing plants and industrial sites face a paradox: the same operational technology (OT) and industrial control systems (ICS) that keep product moving and workers safe are increasingly exposed to cyber threats that can halt production—and even endanger life. For […]

Sovereign-by-Design: Data Residency, BYOK, and Geo-Fencing Patterns for Global AI and SaaS Global software has collided with a patchwork of privacy statutes, sector rules, and national security policies. Where data sits, who can decrypt it, and which jurisdictions can assert control are now product and architectural decisions as important as feature sets. Sovereign-by-Design is the […]

Crypto-Agile by Design: The Enterprise Playbook for Post-Quantum Cryptography Migration Across TLS, PKI, and Code Signing Quantum computing changes the risk calculus for every enterprise that depends on cryptography—which is to say, every enterprise. Even before fault-tolerant quantum machines exist, adversaries can capture encrypted traffic and sensitive binaries today in a “harvest-now, decrypt-later” strategy, waiting […]

From Farm to Thanksgiving Table: Blockchain, IoT Cold Chain, and FSMA 204 Traceability for Safer, Smarter Food Supply Chains Every Thanksgiving, a sprawling, time-critical supply chain springs into synchronized motion. Turkeys leave farms for processors, cranberries and leafy greens move from fields to packers, and refrigerated trucks crisscross the country delivering ingredients to retailers and […]

Carving Truth at the Table: How C2PA Content Provenance and Watermarking Safeguard Enterprises from Deepfakes and Fraud In an age when a convincing fake face, voice, or document can be assembled in minutes, enterprises need a way to carve truth at the table—to present evidence of what happened to a piece of content, who touched […]

Clear the Plate: Machine Unlearning for Enterprise AI—Operationalizing the Right to Be Forgotten Across LLM Fine-Tunes, RAG Pipelines, and Vector Databases Enterprises building AI capabilities are coming to terms with a difficult truth: it is not enough to delete data; AI systems must forget it. The “Right to Be Forgotten” is no longer a privacy […]

From Table Stakes to Tabletop: AI Incident Response and Kill-Switch Playbooks AI is now threaded through customer support, search, code generation, fraud detection, content moderation, and more. As organizations scale beyond pilot experiments, they inherit a new kind of operational risk: models that behave unexpectedly, agents that act autonomously, prompts that are weaponized, and data […]

Stop Overstuffing the Cloud: On-Device AI with NPUs and Small LLMs for Private, Low-Latency Enterprise Apps The last few years turned “put it in the cloud” into a reflex for anything involving machine learning. But as generative AI moves from demos to mission-critical workflows, many enterprises are discovering that funneling everything through remote APIs is […]

Set the Table for Developer Velocity: Platform Engineering and Internal Developer Platforms for Secure, AI-Ready Delivery Introduction: Lay the Table Before Serving the Meal High-performing software teams look fast from the outside, but the secret to their speed is rarely heroics or hustle. It’s mise en place: having everything ready, organized, and within reach before […]

The Shadow AI Potluck: How to Inventory, Govern, and Channel GenAI Tool Sprawl Without Killing Innovation Walk into almost any organization today and you’ll discover a buffet of GenAI tools already on the table—chatbots in browsers, code assistants in IDEs, AI meeting note-takers, writing copilots in office suites, and a dozen browser extensions quietly summarizing […]

Trim the AI Cost Turkey: An AI FinOps Playbook for LLM Cost Optimization, Token Budgets, Caching, Model Right-Sizing, and ROI Guardrails Generative AI unlocked whole categories of experiences—natural language search, instant analytics, copilots, dynamic personalization. It also unlocked a new line item on your cloud invoice that can balloon faster than your user base. The […]

From Pilots to Co-Pilots: An AI Operating Model That Scales Across CRM, Sales, and Customer Service Introduction AI is no longer a side project tucked into a lab; it is becoming the connective tissue across customer-facing teams. The shift that matters most now is from isolated pilots to durable, trusted “co-pilots” embedded in daily workflows—recommendations […]

Glass-Box AI: LLM Observability, Evals, and Feedback Loops for Reliable Production Systems Large language models have moved from demos to mission-critical workflows in customer support, knowledge management, coding assistance, and decision support. Their flexibility is alluring—but that same flexibility can hide unstable behavior, cost surprises, and safety landmines. Reliability comes not from a single clever […]

The AI Bill of Materials: SBOMs, Model Cards, and Dataset Lineage for Supply-Chain-Grade Trust Trust in artificial intelligence is no longer a matter of glossy marketing or one-time audits. As AI systems move from demos to critical infrastructure—triaging patients, underwriting loans, navigating vehicles, coding and deploying software—the question becomes whether an organization can demonstrate supply-chain-grade […]
