Designed in Greece. Made in Greece.
Since 1977, Sigma Security has researched, designed and produced security systems in Agios Dimitrios, Attica. We are the only Greek company in our field that designs and manufactures its own products.
Almost fifty years, one goal.
We started in 1977 with a simple idea: a home's security should rely on products whose makers you know, and where they were made. Today we are one of the largest security system companies in Greece, with products exported to markets abroad.
The control panel, keypad, board and siren are designed by our engineers and tested at our facilities before they reach you. That's how we can support every product for many years after installation.
- ISO 9001 certification for design, production and support.
- Grade 3 and Grade 4 sirens to European standard EN 50131.
- Award-nominated design: ERIS and the PROTEUS keypad were nominated for a Red Dot award.
- Sigma Monitoring: Alarm Receiving Centre for round-the-clock monitoring.
- Sigma Innovation Lab: seminars for installers and professionals.
From the engineer's screen to your home.
We design the circuit boards, make them on our own SMT line, then assemble and test them one by one. When something needs improving, the team that designed it is on the same floor as the team that makes it.










Greek products in international markets.
We present our products at international security exhibitions, such as Intersec in Dubai, one of the largest in the Middle East.
Our products are exported to markets abroad. The same team that designs and makes them in Agios Dimitrios presents them to installers and partners from other countries.


Training from the people who make the products.
Since 2020, we have run seminars for installers and security professionals at the Innovation Lab at our headquarters in Agios Dimitrios.
- Technologies and products Installation, programming and new technologies in security systems.
- Design and planning How to plan and design a system for a home, shop or business.
- Management and growth Skills to organise and grow your business.
What “Security First” means to us
Design with a purpose
A security product must be reliable first and attractive right after. We don't sacrifice one for the other.
Supporting the installer
Technical support, training and tools for our partners, because a proper installation depends on them.
Long-term support
Software updates, spare parts and technical support for years after purchase.
Bring Sigma to your market.
We are looking for distributors abroad for our alarm systems and Grade 3 and Grade 4 sirens, designed and made in Greece since 1977. Get in touch and let's talk about working together.
