A primeira empresa que testa Vulnerabilidades Web do Brasil

Análise de Vulnerabilidades

A ON-Security atua na área de Segurança da Informação com o rastreamento, detecção e solução de vulnerabilidades e fragilidades de websites através de seu sistema pioneiro na América Latina, utilizando as tecnologias mais avançadas para impedir que hackers e crackers alterem ou roubem informações institucionais.

Como funciona?

O Scanner realiza diversos testes que revelam brechas na segurança e potenciais portas de entrada, para um invasor, em seu site. Quando você adiciona seus domínios a serem monitorados no sistema, eles passarão por 1 análise por semana. Serão, no mínimo, 4 análises mensais independente do nível do serviço contratado.

Correção de Vulnerabilidades

A partir do mapeamento de vulnerabilidades, é necessário corrigir os problemas encontrados e concluir o procedimento para a segurança. Nossa equipe tem mais de 10 anos de experiência na área da segurança da informação e é altamente qualificada para a execução deste procedimento.

Voltando a postar...

Depois de muito tempo sem ter tempo para fazer posts sobre tecnologia, voltarei a dar dicas sobre tecnologia e segurança da informação.

Abraços a todos.
