AIの価値は、ヒトにとっても亜人にとっても同じだと思います Your developers are already running AI locally: Why on-device inferen

A wave of on‑device large‑language‑model (LLM) deployments is forcing security chiefs to rethink their perimeter. VentureBeat’s latest report reveals that developers across enterprises are embedding models such as DeepSeek‑V3, Llama 3 and Apple’s internal generators directly into laptops, smartphones and edge gateways, bypassing cloud APIs that have traditionally been the focus of security monitoring.
The shift is not accidental. Local inference slashes latency, cuts cloud‑service fees and, crucially for privacy‑conscious firms, keeps proprietary prompts and user data out of external networks. As we reported on 13 April, engineers were already running “big” models on modest notebooks with Ollama and building private Copilot‑style assistants that never leave the corporate LAN. Those experiments have now matured into production‑grade pipelines that ship pre‑compiled model binaries to employee devices.
What makes the trend a “new blind spot” for CISOs is the erosion of visibility. Traditional security tools watch API traffic, cloud‑storage logs and container orchestration events; they do not inspect the byte‑code of a model executing inside a user’s RAM. Threat actors can therefore inject malicious weights, exfiltrate data through covert side‑channel signals, or repurpose a benign model for credential harvesting—all without triggering conventional alerts. The report warns that most organisations lack an inventory of on‑device models and have no signed‑artifact workflow to guarantee provenance.
Looking ahead, the industry is likely to see the emergence of mobile‑device‑management extensions that enforce model attestation, vendor‑supplied runtime integrity monitors and possibly regulatory mandates for AI‑model supply‑chain transparency. Security teams will need to adopt new telemetry—GPU‑usage baselines, inference‑pattern analytics and cryptographic signing of model packages—to close the gap before the next on‑device AI breach makes headlines.
