Por que sua empresa gera tantos alertas, mas ainda assim continua vulnerável

Muitas empresas acreditam que estão seguras porque recebem relatórios, notificações e alertas constantes de suas ferramentas de segurança. O problema é que alerta não é sinônimo de proteção. Na prática, o excesso de alertas pode esconder ameaças reais e criar uma falsa sensação de segurança — exatamente o cenário que os atacantes exploram.

Como detectar e responder a ameaças em tempo real antes que o dano aconteça

“123456”: por que senhas fracas ainda são a principal porta de entrada para ataques cibernéticos

Mesmo com o avanço das tecnologias de segurança, um problema antigo continua abrindo caminho para ataques cibernéticos: senhas fracas. Em pleno 2025, combinações simples como “123456”, “12345” e “password” seguem entre as mais utilizadas no mundo — e também entre as mais exploradas por atacantes. Para empresas, isso representa um risco silencioso, mas extremamente perigoso.

Ataques Cibernéticos em 2025: O Que Aprendemos e Como Não Repetir os Mesmos Erros em 2026

O ano de 2025 deixou um alerta claro para empresas de todos os portes: os ataques cibernéticos continuam evoluindo mais rápido do que muitas estratégias de segurança. Mesmo com investimentos em tecnologia, diversos incidentes poderiam ter sido evitados com práticas básicas, monitoramento contínuo e uma visão mais estratégica de risco.
