The SandBlast Agent is designed to prevent malware from spreading within the network if it enters an end user's system. SandBlast Agent is a lightweight endpoint security solution that protects devices from advanced threats such as ransomware, phishing, zero-day attacks, and data exfiltration. SandBlast Agent uses various technologies such as behavioral analysis, anti-exploitation, anti-ransomware, threat emulation, threat extraction, and forensics to detect and block malware before it can harm the device or the network. The other options are either not the main purpose or not the functionality of SandBlast Agent.
