What M & L-Sec Kft does
M & L-Sec Kft is a Budapest-headquartered low-voltage systems integrator founded in 1995 by Máté Zoltán and Lastyák Árpád, who continue to co-own and manage the company. The firm designs, installs, commissions, and maintains weak current (gyengeáramú) building systems including fire detection, CCTV surveillance, access control, intrusion detection, structured cabling, public address systems, gas detection, intercom, and an integrated graphical building management platform (SBI). Its product portfolio spans leading global brands (Detectomat, Lites, Hikvision, Dahua, Legrand, Paradox, Seawing, Schrack) combined with proprietary planning capabilities delivered through its wholly-owned subsidiary AZA Kft.
The business operates on a hybrid revenue model combining one-time project-based system installation with recurring maintenance and 24-hour emergency service contracts. Pricing is custom and quote-based per project, with no public price list; the largest single project exceeded 1.4 billion HUF. Customer concentration is rooted in long-standing relationships with major Hungarian general contractors (MARKET, KÉSZ, STRABAG, WHB) that collectively award 30-50 projects annually, while the maintenance portfolio spans 300+ clients and 600+ sites across banking, healthcare, industrial, hospitality, retail, government, and cultural sectors. The company holds exclusive Hungarian distribution rights for German Detectomat (since 2004) and Czech Lites fire alarm systems, and is ISO 9001:2015 certified by both EMT and NQA.
In FY2018, M & L-Sec reported revenue of 1.7 billion HUF with 38 employees, 430 million HUF in equity, and a fleet of 35+ vehicles. The firm remains operating as of late 2025, with active hiring and a November 2024 product launch of the Lites wireless MESH fire detection system extending its addressable market into retrofit and difficult-to-cable environments. The company is private, founder-controlled, and operates exclusively within Hungary as a domestic systems integrator.

M & L-Sec Kft competitors and assessment
Company assessmentBroad incumbents
- Bosch Building Technologies: Bosch provides fire alarm, video surveillance, access control, and intrusion detection globally, with a strong installed base in Europe. It competes with M&L-Sec in the same product categories (fire detection PA, CCTV) but at a larger scale and through different channel partners in Hungary.
- Johnson Controls (Tyco): Johnson Controls offers fire detection (ex-Tyco), security, and HVAC controls globally. It is a broad incumbent with overlapping products (e.g., Notifier, DSC) that M&L-Sec also sells or services, but operates at a much larger scale with a focus on integrated BMS rather than project subcontracting.
- Siemens Smart Infrastructure: Siemens' Smart Infrastructure division offers fire detection, building automation, and security systems globally. It is a broad incumbent whose integrated portfolio overlaps with M&L-Sec's low-voltage systems, though it serves much larger projects and lacks M&L-Sec's local subcontractor intimacy in Hungary.
- Honeywell Building Technologies: Honeywell competes in fire detection, access control, and integrated building management across Europe. Like Siemens and Bosch, it operates as a broad incumbent with overlapping product categories but typically targets larger enterprise and multinational deployments than M&L-Sec's local mid-market focus.
Direct peers
- Detectomat GmbH: Detectomat is the German manufacturer of fire alarm systems that M&L-Sec exclusively distributes in Hungary. While technically a partner, Detectomat also sells direct or through other integrators in adjacent markets, making it both supplier and competitive peer in the broader regional fire systems space.
- Schrack Seconet: Schrack Seconet is an Austrian fire alarm and communication systems specialist with strong Central European presence (Hungary through Schrack partner). It is a direct peer offering fire detection, evacuation, and integrated systems — competing head-to-head with M&L-Sec's Detectomat and Lites distribution-led model in Hungary.
- Procontrol Electronics Kft: Procontrol is a Hungarian security and building automation systems integrator serving construction, industrial, and institutional clients. Direct peer with overlapping product offerings (access control, CCTV, fire, BMS) and a similar contractor-led GTM in Hungary.
- Radwár Kft (Ravel Group): Radwár is a Hungarian low-voltage systems integrator (fire alarm, security, structured cabling) with similar mid-market subcontractor positioning. Operates in the same Hungarian construction-subcontractor channel and frequently competes for the same general contractor projects.
Emerging players
- Future Electronics Kft: Hungarian low-voltage systems integrator offering fire, security, and BMS services. As a smaller or emerging player in the same Hungarian market, it competes with M&L-Sec for similar construction-firm and maintenance contracts, though with narrower scale and brand visibility.
Regional players
- Pilz Hungária Kft: Pilz is a German safety automation specialist with Hungarian operations, focused on functional safety, fire/industrial safety systems. As a regional player with similar product scope (safety/fire systems integration) serving the same Hungarian customer base, it competes most directly with M&L-Sec in industrial safety installations.
