Avast Ultimate Business Security vs HarfangLab EPP Antivirus: 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.

HarfangLab EPP Antivirus

Startups and SMBs with multi-OS environments will get real value from HarfangLab EPP Antivirus because it handles Windows, macOS, and Linux detection from a single dashboard without the licensing bloat of larger platforms. The IKARUS engine delivers signature-based detection plus behavioral analysis, and the virtual sandboxing for file execution actually catches polymorphic malware that signature-only tools miss. Skip this if you need NIST Respond capabilities built in; HarfangLab is detection and containment focused, leaving incident response and remediation to your other tools.
