- Sophos Endpoint Exploit Prevention
Note that these are Sophos marketing titles. Depending on the country and partner/reseller, the orderable product names may differ. For example, one partner website shows the product names as Sophos Server Protection for Windows, Linux and vShield.
Sophos antimalware software contains a Management Interface (Console+Server+Update Manager) that runs in a separate Windows Server and Antivirus (Agent) software that runs in the ASM/SBA.
Prerequisites
We recommend running the Management Interface and Antivirus separately to conserve CPU processing in ASM/SBA.
- Unable to show "metadata-from": No such page "_space_variables"requires a separate off-board server (distinct and separate from theUnable to show "metadata-from": No such page "_space_variables"ASM) to be the execution platform of the Sophos Management Interface. This deployment model provides the following benefits:
- A single management interface can manage multiple Unable to show "metadata-from": No such page "_space_variables"'s with the SBA.
- The Sophos Agent minimizes the extra processing load on the Unable to show "metadata-from": No such page "_space_variables"'s ASM.
- A single management interface can manage multiple

Sophos Anti-Malware Operation Modes
Differences Between Continuous and Full-Scan Operation
Continuous Operation:
- Sophos Anti-Malware runs in the background and continuously protects the ASM in real time.
- Sophos Anti-Malware contributes a negligible additional load on the CPU. The SBC ASM can be driven to maximum call capacities without regard to the Sophos software.
Full-Scan Operation
- Sophos Anti-Malware can perform a complete system scan ("full scan") and the period of the full scan should be initiated according to Sophos instructions
- When performing a full scan, Sophos Anti-Malware uses a significant proportion of RAM and CPU resources. Full scans should be scheduled for off-peak periods.
