We think like attackers. We protect with AI.
Boutique team led by a senior architect with 30+ years. On-premise private LLMs, MLSecOps, ICS/OT and NIS2/EU AI Act compliance. No intermediaries, no third-party cloud.
▊ 30+ yrs · AI-amplified team · Zero third-party cloud
Architect's 30-yr track record — real deliveries from prior engagements
Enterprise Cybersecurity Services
30+ years of field experience. Fully custom agentic workflows (n8n, LangChain, CrewAI, LangGraph) with security hardening, prompt injection filtering and MLSecOps controls built in from day one. Real security — not compliance theater.
Private LLMs & B2B AI Agents
100% on-premise LLMs. Fine-tuning, RAG, multi-agent orchestration. Your data never leaves your infrastructure.
MLSecOps & Adversarial Defense
AI pipelines against prompt injection, data poisoning and model evasion. Aligned with NIST AI RMF and OWASP Top 10 LLMs.
Red/Blue Team with AI
AI-augmented pentesting and threat hunting. TTP simulation (MITRE ATT&CK). SIEM optimization with fine-tuned LLMs.
ICS/OT Security
Industrial, agrotech IoT and building OT. ISA/IEC 62443. Purdue IT/OT segmentation. Continuity-first design — scoped assessments you can buy this quarter.
AI-Powered Automated Compliance
ISO 27001 · NIS2 · GDPR · EU AI Act implemented with AI. Automated audits, gap analysis, real-time evidence collection.
CISO as a Service / Senior Architect
Senior security leadership on demand. Strategy, roadmap, incident management. Available as vCISO, in-house or B2B partner.
Your data never leaves.
Not a selling point — a technical fact.
Most AI consultants send your data to OpenAI, Anthropic or Google — they just rebrand the API. Here, fine-tuned models (Qwen3.5, DeepSeek, Llama, Mistral) run on dedicated GPU hardware owned and operated by PROTISEC. Zero inference cost, zero third-party exposure.
Proprietary AI inference nodes · Enterprise NAS storage · Proxmox + OPNsense · Managed VLANs · Internal SOC
Fully custom agentic workflows (n8n, LangChain, CrewAI, LangGraph) with prompt injection filtering, privilege isolation and MLSecOps controls — built in from day one, not bolted on.
ASM/C/C++ → MLSecOps → Agentic AI. No generational gaps, no marketing without technical foundation
Senior architect + AI agents working in parallel — the same boutique logic McKinsey used against Accenture, applied to cybersecurity. No overhead, no hidden subcontracting.
How we work
No sales deck, no middle layer. You talk to the architect — from the first call to hardened deployment.
Technical Briefing
A 30-min call, no deck. We map your stack, threat surface and real constraints — and tell you straight if we're not the right fit.
Threat Assessment
We think like the attacker — recon, exposure, ICS/OT and AI attack paths mapped to MITRE ATT&CK. You get a prioritized findings map, not a 200-page PDF.
Architecture Design
A hardening blueprint — on-premise, zero third-party data exposure. You approve the design before a single change ships to production.
Hardened Deployment
We deploy, validate against ATT&CK, and hand over runbooks your team can own. Continuous retainer optional — never locked in.
Proven in Production
Real cases from the architect's career — prior clients and engagements
Military ICS/OT infrastructure — 500+ workstations, 99%+ uptime
Defense industry optronics manufacturer (thermal imaging, night vision, border security systems for 50+ countries). ICS/OT infrastructure security and maintenance for 500+ CAD/CAM workstations. Zero production stoppages, 99%+ uptime over 18 months.
Private LLM + RAG for legal automation — EU AI Act compliant
Tech partner for Lleida-based law firm (debt consolidation, credit reclaims). Custom LLM fine-tuned on 100+ domain datasets with reasoning improvements. Private inference, RAG pipeline, document automation, OSINT intelligence. Full compliance with GDPR, EU AI Act.
