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
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
Critical industrial infrastructure. ISA/IEC 62443. Purdue model IT/OT segmentation, real-time anomaly detection. 99.95% uptime.
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
SIEM refactoring + ICS/OT hardening with AI
Legacy OT environment with inadequate IT/OT segmentation. Deployed custom agentic pipeline (n8n + LangChain + LangGraph) with hardened security layer for anomaly detection, Purdue model segmentation, fine-tuned LLMs for SIEM triage and automated response.
100% on-premise AI + NIS2 compliance from scratch
Law firm with strict data confidentiality requirements. Deployed private LLMs (Llama + Mistral fine-tuned on legal docs) with custom agentic pipeline, full NIS2 certification, automated GDPR management via AEPD DPO certification.
Real outcomes. No hype.
Anonymous at client request. Sector and metric are real.
"The Purdue segmentation was completed without a single production stoppage. For the first time in five years, we have real confidence in our OT perimeter — not just on paper."
"We passed ISO 27001 on the first attempt. The automated evidence collection alone saved three months of manual work. The auditors were surprised — we were not."
"Patient data never leaves our infrastructure. The private LLM processes 3,000 daily records with zero cloud dependency. GDPR compliance went from a checkbox to a technical fact."
Fixed-Price Security. Starting Today.
One deliverable, one price, one day. No long contracts.
