Dectar is a European cybersecurity company dedicated to safeguarding organizations by predicting, detecting, and responding to cyber threats before they can cause harm.
With headquarters in Ireland and Italy, Dectar combines innovation and expertise to protect institutions and enterprises, ensuring the resilience of their critical infrastructures and data.
Our flagship platform, ACSIA SOS™ (Security Operations Solution), is an advanced detection, response, and remediation solution powered by a unique open detection engine. It delivers Predictive, Proactive, and Reactive defense capabilities, while automated remediations simplify operations, reduce costs, and strengthen overall security posture.
At Dectar, we go beyond protection: we enable organizations to operate with confidence in an increasingly complex digital landscape.
Our journey began on a Friday a few years ago…
Dectar was born from the experience of Stefan Umit Uygur, an expert in cybersecurity and IT systems management, and a strong advocate of open source. His revolutionary approach stems from a key concept: to effectively prevent cyberattacks, companies must learn to think like a hacker.
Over the years, the company has benefited from the support of Enterprise Ireland—the government organization responsible for the international growth of Irish companies—which, in addition to supporting Dectar’s international development, also became an investor.
After initial funding from the Competitive Startup Fund (CSF) and the High Potential Startup Fund (HPSU), Dectar received an investment from the French company ITrust, with which it established a partnership for the French market.
Dectar has developed a cyberdefense solution to predict and prevent cyberattacks.
Dectar core product, ACSIA SOS (Security Operations Solution), acts as an aggregator of solutions, incorporating the typical features of SIEM, EDR, XDR, NDR, and other tools — but with a unified and simplified approach.
Unlike specialized solutions focused on a single area (such as antimalware, antivirus, or niche intrusion prevention systems), ACSIA SOS offers a centralized platform built around prevention — preventing cybercriminals from gaining deep knowledge of digital assets — combined with ease of use and significantly lower costs compared to managing a fragmented ecosystem of products.

Dectar core product, ACSIA SOS (Security Operations Solution), takes the Extended Detection and Response solution to the next level via enhanced prediction and prevention capabilities, ultimately hiding and sheltering IT infrastructures from cybercriminals.
Recently a new groundbreaking solution has become available: ACSIA CRA (Cyber Risk Assessment). This innovative prevention tool can assess the cyber posture of a company/institution and spot its vulnerabilities before an attack takes place.
The ACSIA products have an unique value proposition and a clear differentiation from the current market solutions in the cybersecurity industry: their primary objective is to predict and prevent, stopping threats from getting anywhere near your digital assets.

In 2021, Dectar marked a key milestone in its growth with the entry of Cysero created to support startups and innovative SMEs in the fields of robotics and cybersecurity, foster the development of an Italian innovation hub.
Thanks to this support, Dectar Limited, the Irish parent company, established its Italian subsidiary, Dectar Italia Srl, and opened offices at the Kilometro Rosso Science and Technology Park in Bergamo, strengthening its research and development activities and contributing to the spread of a data protection model capable of meeting the needs of both large enterprises and SMEs.
In 2025, the Cysero fund – together with D&C Governance Technologies – signed an agreement providing for a reserved capital increase in Dectar, aimed at supporting the company’s growth trajectory.
The funds raised will be allocated to:
- strengthening research and development activities;
- consolidating commercial presence in international markets;
- relocating the Italian operational headquarters to Calabria, in Cosenza, under the name DectarLab, with the goal of generating a positive impact in terms of digital skills, qualified employment, and local technological development.
In addition to holding the CEO position at Dectar, Stefan has been collaborating for years as a consultant with the National Cybersecurity Agencies of several countries, including Ireland, Israel, the United States, and the United Kingdom.
Stefan is also currently involved in advisory with the National Cyber Security Centre in the Republic of Ireland. Stefan recently testified in the Irish Oireachtas or Senate at the Joint Committee for Transport and Communications discussion on a common vision for cyber security.
