AI security
& secure LLM integration
LLMs in industrial systems are only viable when risks such as prompt injection are designed in from the start. We review your architecture against the OWASP LLM Top 10, harden LLM interfaces, and run firmware security audits.
LLM integration
Secure LLM systems
OpenAI GPT API
Chat Completions, structured outputs, streaming
Function/tool calling
Deterministic tool execution with validation
MCP (Model Context Protocol)
Secure context handoff to agents
Agent orchestration
Multi-step pipelines with supervisor control
Prompt injection defense
Input sanitization, output filtering, allowlists
Rate limiting & audit logs
Monitoring all LLM requests and responses
Firmware security
Critical threats
Unauthorized instruction execution via crafted inputs — business‑critical for AI agents in industrial processes.
Unfiltered LLM output can lead to XSS, SQL injection, or unauthorized code execution.
OTA updates without signature verification allow malicious firmware to be deployed to field devices.
Hardcoded passwords in firmware — one of the most common findings in IoT security audits.
CRA context: from technical audit to compliance foundation
A firmware security audit per OWASP Embedded Top 10 is the technical foundation — but from 11 September 2026 it becomes a regulatory duty. The Cyber Resilience Act (CRA) makes security by design binding for every machinery manufacturer.
- → Every device with firmware = product with digital elements under CRA (EU) 2024/2847
- → For industrial control systems (PLC, safety controller): IEC 62443-4-2:2019 as primary OT security standard — complements OWASP at MCU/SoC level
- → SBOM per CRA Art. 13: machine-readable component inventory — Solvetronix creates SBOMs for legacy products too
