Dectar

Dectar is a Dublin-headquartered cybersecurity vendor that rebranded from 4Securitas in January 2024, combining ‘detect’ and ‘radar’ into its new name to better reflect its predictive, proactive positioning. The company’s flagship platform, ACSIA SOS (Security Operations Solution), functions as an aggregator that unifies SIEM, EDR, XDR, and NDR capabilities into a single simplified system, aimed at organizations that cannot run or afford several overlapping point tools. The product line also includes ACSIA CRA, a cyber risk assessment tool, and a bundled offering paired with Fortinet’s FortiGate firewall.

Founded in 2017 by Stefan Umit Uygur and Donal Kerr as 4Securitas, the company has raised roughly $2.36 million across two funding rounds from Enterprise Ireland, French cybersecurity firm iTrust, and Italian investment fund AVM Gestioni, positioning it as a seed-stage European vendor rather than a heavily venture-backed one. It maintains offices in both Dublin, Ireland and Bergamo, Italy, and states it advises governments in Ireland, Italy, and the UK on cyber policy.

Dectar’s own site features named client quotes from MCN Media, Euclidea, and Coeclerici describing the platform as filling gaps between siloed security tools and providing effectively an always-on security engineer; these are useful directional signals but are vendor-selected testimonials rather than independently audited case studies. The company has also demonstrated specific detection capability publicly, such as a documented release adding Log4j vulnerability detection shortly after that vulnerability’s disclosure.

As a small, seed-funded aggregator platform competing against much larger XDR vendors, Dectar’s differentiation is affordability and simplicity for SMBs rather than best-in-class detection engineering, and buyers should weigh that trade-off against its limited independent validation.
