ManageEngine provides a suite of IT management software for networking and security.
EventLog Analyzer is ManageEngine's (a division of Zoho) log management, auditing, and IT compliance tool with lightweight SIEM capabilities. It collects, correlates, and reports on logs from servers, network devices, and applications, with strong support for Windows event logs and regulatory compliance reporting. It offers a free tier plus affordable annual editions and can be deployed on-premises or in the cloud.
Mezmo (formerly LogDNA) is a telemetry pipeline and log management platform for ingesting, parsing, enriching, and routing high-volume logs, metrics, and traces before they reach downstream storage or analytics. Data can be collected through Mezmo Edge, OpenTelemetry, or direct integrations, with pipeline controls that reduce downstream cost and improve query performance. It is HIPAA-compliant, delivered as SaaS, and oriented toward organizations managing large, cost-sensitive log streams.
Grafana Loki Grafana LabsGrafana Loki is a horizontally scalable log aggregation system that indexes only metadata labels rather than full log content, keeping storage costs low by writing to object storage. It integrates tightly with Grafana dashboards and the broader LGTM stack (Loki, Grafana, Tempo, Mimir) for logs, metrics, and traces. Loki is free and open source for self-hosting, and is also available as a managed service through Grafana Cloud with a free tier and usage-based paid plans.
Axiom AxiomAxiom is a serverless, OpenTelemetry-native log management and event platform that ingests data without sampling or manual index management and separates compute from storage for low cost at scale. Pricing is usage-based across data loading, query compute, and compressed storage rather than per host. Axiom is cloud-hosted only and integrates natively with tools such as Vercel and Next.js, though its APM and RUM capabilities are less mature than full-stack competitors.
