Cybersecurity consulting and audits: IT, OT, IoT, pentesting, cyberdefence, secure development and quantum computing

The problem we solve

Beyond IT, including computers, email and servers, many companies depend on operational technology such as machinery, PLCs and SCADA, and on IoT devices such as sensors and cameras.

Systems originally designed to be isolated are now connected to corporate networks and the internet. Software also underpins most business operations: custom applications, integrations and firmware. Adding security at the end costs more and works less well. Testing defences before an attacker does is essential, while quantum computing threatens much of today’s encryption.

Cybertix addresses IT, OT, IoT, secure development, offensive audits, cyberdefence and post-quantum cryptography together because these areas increasingly overlap.

Five specialties, one team

Industrial (OT) and IoT cybersecurity

We protect industrial systems under one non-negotiable principle: production must continue. Every intervention is designed around business continuity.

• Inventory and discovery of PLCs, IP cameras, sensors and undocumented assets.
• IT/OT network segmentation to prevent incidents from crossing between offices and production.
• Risk and compliance assessment aligned with NIS2, IEC 62443 and ENS where applicable.
• Secure remote access for external maintenance providers.
• Specific awareness training for plant personnel.

Secure application development

Security by design brings security into the earliest stages of application and product design and development. Preventing a flaw in design is more effective and less expensive than fixing it in production.

We adapt the work to your size, sector and number of projects. Web and mobile apps, APIs, cloud applications, custom business software, industrial or IoT firmware and AI applications all benefit.

• Security requirements and threat modelling from the design stage.
• Architecture and code reviews.
• Automated security tests integrated into the development cycle (DevSecOps).
• Dependency management and SBOM (software bill of materials).
• Vulnerability management and a coordinated disclosure policy.
• Secure development aligned with IEC 62443-4-1 for industrial products.
• Training for development teams.
• Crypto-agile design to make future post-quantum migration easier.

Secure development supports compliance

NIS2, ISO 27001, the Cyber Resilience Act and IEC 62443 call for security in the development and maintenance of systems and products. Building it in from the start is the clearest route to compliance.

Manufacturers: Cyber Resilience Act and Machinery Regulation

If you manufacture machinery, industrial equipment or connected devices, the CRA requires reporting exploited vulnerabilities and serious incidents from 11 September 2026, including in products already sold. Cybersecurity CE marking applies from 11 December 2027. The EU Machinery Regulation 2023/1230 applies from 20 January 2027. We help with secure development (IEC 62443-4-1 and 4-2), SBOMs, vulnerability management and PSIRT.

Offensive cybersecurity audits

Offensive cybersecurity takes an attacker’s perspective, with written authorization and agreed rules of engagement, to find and demonstrate weaknesses without putting operations at risk.

Offensive testing also supports compliance: NIS2 and ISO 27001 call for assessing security measures and managing vulnerabilities; DORA requires resilience testing, including advanced threat-led testing for certain entities.

• Vulnerability assessment: broad, recurring reviews of infrastructure, applications and cloud environments, prioritized by business risk.
• Pentesting: in-depth attack simulations against internal and external networks, web apps and APIs, mobile apps, WiFi, cloud and, with additional care for production continuity, OT and IoT.
• Threat intelligence: tracking campaigns, exposed credentials and assets relevant to your company or sector to guide tests and anticipate threats.

Cyberdefence: infrastructure and network security

Cyberdefence protects and monitors infrastructure so attacks can be prevented, detected early and contained quickly.

Offence and defence reinforce each other: audit findings improve protection, while defence observations guide future tests.

• Secure network architecture: segmentation, secure remote access and Zero Trust models.
• Hardening of servers, endpoints, firewalls and exposed services.
• Cloud and hybrid environment security.
• Continuous monitoring, detection and incident response, alongside our All in One 24×7 SOC and AI automation services.
• Exercises and simulations to practise response through training and CYBERFORGE.

Quantum computing and post-quantum cryptography

Harvest now, decrypt later describes the theft of encrypted information today so it can be decrypted when quantum computing makes that possible. Data that must remain confidential for years needs protection now.

You do not need to be a bank or multinational: understanding your starting point early makes the transition more orderly and affordable.

• Cryptographic exposure assessment across communications, storage and digital signatures.
• Prioritization based on the value, criticality and lifespan of each dataset.
• Roadmap based on NIST ML-KEM, ML-DSA and SLH-DSA standards, including hybrid approaches where appropriate.
• Implementation support and coordination with current technology providers.

Our consulting methodology

1. 1Initial assessment tailored to your size, sector, IT/OT/IoT assets, applications, attack surface and cryptographic exposure.
2. 2Prioritization using business criteria, not just technical severity.
3. 3A concrete, realistic strategy phased over time.
4. 4Implementation support from our team or coordination with your existing providers.
5. 5Periodic review as threats, regulation and the quantum timeline evolve.
