Avast Ultimate Business Security vs ESET Server Security: Side-by-Side Comparison (2026)

Avast Ultimate Business Security

Startup and SMB security teams with 1-100 devices need endpoint protection that doesn't require a dedicated admin, and Avast Ultimate Business Security delivers that through a cloud-based management console that handles patching, antivirus, and cross-device enforcement without heavy operational lift. The platform covers both PR.PS platform security and DE.CM continuous monitoring in the NIST CSF 2.0, meaning you get vulnerability patching and anomaly detection in one deployment. Skip this if you need advanced threat hunting, forensics, or behavioral EDR; Avast's strength is preventive coverage, not incident investigation.

ESET Server Security

SMB and mid-market ops teams protecting Windows and Linux servers will get the most from ESET Server Security because its behavior-based ransomware detection actually stops encryption-stage attacks instead of just flagging files after encryption starts. The multilayered malware detection across pre-execution, execution, and post-execution phases, combined with HIPS and network attack protection, gives you DE.CM and DE.AE coverage that catches what signature scanning misses. Skip this if you need deep incident response automation or forensics; ESET Server Security is detection and prevention focused, leaving recovery workflows to your team.
