The Ótima Digital Group, one of the four largest telecommunications companies approved by Anatel and broker of telephone operators in Brazil, has stood out in protecting against fraud in text messages. With the daily sending of over 25 million communications (SMS and RCS), the company invested in a robust solution capable of filtering 98% of malicious messages, ensuring user safety
The security strategy of the Ótima Digital Group involves a multi-layered approach that combines rigorous authentication and encryption practices. These measures have been essential in drastically reducing the incidence of SMS scams, a criminal practice that aims to deceive victims and extract sensitive information. According to the 17th Brazilian Yearbook of Public Security, an average of 208 occurrences of this type of crime were recorded per hour last year
Fábio Manastarla Ferreira, security specialist at Grupo Ótima Digital, highlights the adoption of the principle of "security by design". "Here at Ótima Digital, no new server is enabled without the security templates and applications being applied, affirms Ferreira. This proactive method protects against known threats and adapts to defend against new types of attacks
Two-factor authentication, or two factors, it is a fundamental measure adopted by all services of the Group. This extra layer of security ensures that, even if a criminal obtains a customer's username and password, he will still need a second factor — usually a code sent via SMS or an authentication token — to access the account. With this key, that seems small, you already avoid 98% of frauds, highlights Ferreira
All communications between Ótima Digital Group and its major partners, as operators, Google and Meta, are encrypted. Cryptography is applied both in SMS sending channels and in other forms of digital communication, keeping user data safe and private, protecting them from malicious interceptions, affirms Ferreira
Ferreira also emphasizes the importance of advanced edge control infrastructure, known as BGP (Border Gateway Protocol), that helps manage routed and delivered data packets, minimizing the chances of attacks and interceptions
Despite technological advancements, Ferreira warns about the importance of consumer education. He suggests that users always verify the authenticity of the websites and messages they receive, especially when they contain external links. It is necessary to pay attention to the links that are received!”, concludes
