Engineering-focused coverage of defensive AI. Guardrail architecture, classifier ensembles, model hardening, output filtering, refusal training, and the response patterns that hold under adversarial pressure in production systems.
A deep-dive into layered output filtering for production LLMs — combining semantic classifiers, regex scrubbing, and LLM-as-judge techniques to catch harmful, policy-violating, and hallucinated content before it reaches users or downstream systems.
How to build a production observability stack for LLM outputs — covering anomaly detection pipelines, latency threshold alerting, output drift signals, and concrete alerting logic you can deploy today.
A technical guide to preventing prompt injection attacks in production LLMs — covering system prompt hardening, privilege-separated architectures, instruction hierarchy, and defense-in-depth patterns with vulnerable vs. hardened code examples.
How to build an internal adversarial testing pipeline for LLM applications using garak, promptfoo, and custom probes — with a CI integration pattern that catches security regressions before they reach production.
How to architect a multi-layer output filtering pipeline for production LLMs — covering deterministic guards, ML classifiers, schema validation, and async sequencing patterns to minimize latency while maximizing coverage.
A systems-level guide to preventing prompt injection attacks in production LLMs — covering defense-in-depth layering, structural prompt architecture, privilege separation, and continuous adversarial validation with concrete implementation patterns.
A practical engineering guide to rate limiting, quota enforcement, and abuse detection for AI API endpoints — covering token-bucket algorithms, per-user quotas, fingerprinting, and behavioral anomaly detection for LLM services.
A technical breakdown of proven AI defense techniques for LLMs — from input guardrails and prompt hardening to dual-model architectures and red teaming, mapped to OWASP and NIST frameworks.
How to implement LLM guardrails across input validation, output filtering, and runtime enforcement — with concrete patterns, tooling comparisons, and latency trade-offs for production deployments.
