The National Learning Service (Sena), one of the most recognized institutions in Colombia in technical and technological training, has issued an alert to citizens and its suppliers. The entity has detected a worrying increase in attempted fraud related to its contracting and bidding processes.
According to an official statement, Unscrupulous individuals are using false telephone numbers, signatures and emails, posing as representatives of the Sena. The aim of these scammers is to deceive both citizens and suppliers who participate in bidding processes and purchases of goods and services.
The institution has emphasized that all its public procurement processes are managed exclusively through the SECOP platform (Electronic Public Procurement System), administered by the National Public Procurement Agency. This measure seeks to guarantee the transparency and legality of all procedures.
To help identify legitimate communications, SENA has reminded participants and citizens in general that their official emails always end with the domain “@sena.edu.co”. Any message that does not meet this criteria should be considered suspicious and reported immediately.
Additionally, the entity has provided official telephone numbers for citizen assistance: in Bogotá, 6017366060, and for the rest of the country, the toll-free line 018000 910270. Citizens are urged to use these channels exclusively for any queries or procedures related to the institution.
This situation highlights the growing sophistication of the methods employed by fraudsters, who take advantage of the reputation of respected institutions to carry out their illicit activities.
SENA has called on citizens to remain alert and carefully verify the authenticity of any communication that allegedly comes from the institution. It also recommends reporting any suspicious activity to the competent authorities and to the institution itself.
