§ 01 · CORE EXPERTISEFour practices

Four practices, one team.

No hand-offs, no silos. Our engineers design, secure and operate critical infrastructure end-to-end — from the CI/CD pipeline to the industrial PLC.

/ 01 — CYBERSECURITY

Cybersecurity & Audit

Technical & managerial audit, pentesting, vulnerability assessment — including industrial cyber-physical systems. NIS2 & ISO 27001 advisory, end to end.

PENTESTING NIS2 IEC 62443 CISM PKI SIEM
/ 02 — DEVSECOPS

DevSecOps & Automation

CI/CD pipelines, infrastructure orchestration, real-time monitoring and alerting. Security embedded by design, not bolted on at the end of the cycle.

/ 03 — CLOUD OPS

Cloud & Infrastructure

Architecture, deployment and day-to-day operations. Cloud-agnostic by design, open-source tooling — no vendor lock-in, full portability, full sovereignty.

/ 04 — R&D

R&D & Innovation

Research projects in cloud computing and industrial cybersecurity — cyber-physical system vulnerability assessment with tier-1 industrial partners.

§ 03 · WHY GUARDISThree principles · Four steps

Twenty years of field, zero theory.

Guardis is built by operators. Every recommendation comes from an engineer who has shipped, debugged and defended production systems — often on both sides of the firewall.

Field Expertise

20 years of real operations on critical infrastructure — not theory, daily hands-on experience across cloud, industrial systems and security engineering.

Built-in Security

Cybersecurity has been in our DNA since day one — security by design, aligned with state-of-the-art standards across cloud and on-prem.

Zero blind spots

Infra, automation and monitoring handled as one — not in silos. One point of contact, from initial design all the way to production.

/ IN PRACTICE From audit to day-2 operations — pick any step, or chain them end-to-end.
Scope & assess
Technical audit, threat model, NIS2 gap analysis.
Design & harden
Architecture, controls, identity, monitoring — defined first.
Automate & deploy
CI/CD, infra-as-code, observability — reproducible, versioned.
Operate & evolve
Day-2 monitoring, remediation, continuous hardening.
