Artificial intelligence has become part of everyday work. Employees use ChatGPT to draft emails, Gemini to summarize documents, and other AI tools to speed up research, coding, or content creation. While these tools can improve productivity, they also introduce a new security challenge that many small and medium-sized businesses don't realize they already have. The problem isn't AI itself. The problem is Shadow AI. When employees use AI applications without IT approval or sec

Cybercriminals no longer need malware to compromise a business. In many Microsoft 365 incidents, attackers simply steal valid credentials and sign in like a legitimate user. When that happens, there may be no ransomware, no antivirus alert, and no obvious warning. The first indication could be an unusual login, a suspicious email, or a report from a customer.

Employees join and leave, new applications are connected, devices change, and Microsoft regularly introduces new security features. Over time, these changes can create security gaps that inc

Cyberattacks targeting Microsoft 365 environments continue to evolve, but many successful attacks still exploit the same weaknesses: stolen passwords, phishing emails, excessive permissions, and unprotected devices. The good news is that Microsoft 365 includes a wide range of built-in security capabilities that can significantly reduce these risks when configured correctly. While no security control can guarantee complete protection, enabling the right features creates multip

El compromiso de una cuenta en Microsoft 365 es uno de los incidentes más comunes y más sensibles para cualquier organización. Puede comenzar con una contraseña filtrada, un inicio de sesión desde una ubicación inusual, un token reutilizado, una regla maliciosa en Exchange Online o una campaña de business email compromise. El problema no suele ser solamente técnico. Cuando una cuenta está comprometida, el equipo de TI necesita responder rápido a varias preguntas: ¿Quién acced
