Difenda Managed Email TDR FAQ

What Is Managed Email Security?

Managed email security is a service that provides proactive measures to secure an organization’s email infrastructure against cyber threats such as malware, phishing, and spam. This service is usually offered by MSSPs, like Difenda and often include features such as email filtering, anti-malware, anti-spam, and email encryption storage.

Overall, managed email security provides a comprehensive approach to protecting an organization’s email infrastructure against cyber threats. By outsourcing email security to a MSSP like Difenda, organizations can focus on their core business operations while ensuring that their email system is secure and protected.

What Is Threat Detection And Response?

Threat detection and response is a process of identifying and responding to cybersecurity threats that target an organization’s digital network or infrastructure. The goal of threat detection and response is to prevent or minimize the impact of cyber attacks by reducing attacker dwell time and responding quickly and effectively to threats.

The threat detection process generally involves monitoring an organization’s network and infrastructure for signs of suspicious or malicious activity. This can include analyzing network traffic, reviewing logs and alerts from security systems, and conducting vulnerability assessments. Threat detection tools such as intrusion detection systems (IDS) and security information and event management (SIEM) systems are used to automate this process and alert security teams to potential threats.

Once a threat is detected, the response process involves analyzing the threat and determining the appropriate action to take. This may involve containing the threat by isolating affected systems or disabling network access, investigating the source of the threat, and implementing remediation measures to prevent similar threats from occurring in the future.
