The specific release, version 9.1.2063.0, represents a stable build within the ESET Endpoint product line, focusing on heuristic detection, firewall control, and remote management capabilities.

1. Multi-layered Protection ESET is renowned for its lightweight footprint and high detection rate. Version 9.1 utilizes cloud-based whitelisting and scanning to protect against:
2. Firewall and Network Attack Protection This version includes a built-in two-way firewall that inspects incoming and outgoing traffic. It helps prevent unauthorized remote access and stops malware from communicating with command-and-control servers. The Network Attack Protection module blocks malicious network traffic at the network layer.
3. Device Control Administrators can enforce policies regarding external devices. This is critical for preventing data leakage (DLP) via USB drives or external hard drives. Access can be granular—allowing specific device types or specific device IDs while blocking others.
4. Web Control This feature allows administrators to block specific categories of websites (e.g., gambling, social media, adult content) based on company policy, aiding in productivity and security.
