"Critical infrastructure is not just one of squareTec's sectors. It's the sector where we started, and it defines our expertise."

‍

Critical infrastructure is squareTec's most important area of activity. We design and integrate solutions for systems whose disruption or shutdown directly impacts state security, the continuity of societal functioning, and economic stability.

squareTec acts as a technology partner and security architect for critical infrastructure — combining technical security, cybersecurity, IT/OT, data analytics, and software into one cohesive, manageable ecosystem. Our solutions are designed to operate in sensitive, regulated, and high-operational-risk environments.

‍

Technical Security of Critical Infrastructure Facilities

squareTec designs and integrates advanced systems covering:

• perimeter and critical zone protection,
• video and sensory monitoring,
• access control and identity management,
• protection of distributed and multi-location facilities.

The solutions are adapted for continuous 24/7 operation, large scale, and high reliability requirements — characteristic of energy, transport, telecommunications, and industrial infrastructure.

Cyber-Physical Convergence

Critical infrastructure is a primary target for hybrid attacks today. That's why squareTec integrates:

• CCTV, perimeter, and access control systems,
• network, OT, and control system security,
• monitoring and event correlation systems (SIEM),
• common incident response procedures.

This allows physical and digital events to be analyzed together, resulting in a faster, more consistent, and effective organizational response.

Data Analytics and AI for Critical Infrastructure

squareTec uses data analytics and artificial intelligence to:

• detect anomalies and threats,
• correlate events from multiple systems,
• support operational and crisis decisions,
• enhance infrastructure resilience.

AI and analytics function as an operational layer of the security system — even in on-premise, isolated, and limited connectivity environments.

Regulatory Compliance and Accountability

squareTec's solutions for critical infrastructure are designed with consideration for:

• national and EU regulations (KSC, NIS2, DORA),
• information security standards,
• user and component accountability,
• audit and access control requirements.

We treat critical infrastructure security as a continuous process — not a one-time technological project.

Why should critical infrastructure choose squareTec?

• This is our key sector — solutions designed from the ground up for CI, not adapted from other markets.
• Experience in sensitive and regulated environments — we don't learn on our clients.
• Role of a Security Architect — responsibility for the entire system, not just a selected component.
• Cyber-Physical Convergence — real resilience against hybrid threats.
• Technological and Data Sovereignty — full control over architecture and information.
