OmniSight vs Graylog
Graylog is a general-purpose log management and SIEM platform — you point it at log sources (syslog, GELF, Beats, APIs) and it ingests, indexes, and searches the full content. OmniSight is a purpose-built, metadata-only network visibility agent with SOC triage built in. The core difference: Graylog's job is indexing log content; OmniSight is designed to never collect it.
storage Choose Graylog if...
- circleYou need a general-purpose log management/SIEM platform that ingests and indexes logs from any source across your whole environment.
- circleYou want AI-powered automated investigations and behavioral anomaly detection (Graylog 7.1 / Spring 2026 added an Impossible Travel Detector, automatic case creation, and Sigma rule sourcing from private repos).
- circleYou're prepared to operate an Elasticsearch/OpenSearch + MongoDB backend, sized for your log volume (public estimates: $500-5,000+/mo infrastructure, 20-40 hrs/mo operational labor for self-managed Graylog Open).
- circleYou want the option to scale into Graylog Enterprise/Security (from ~$15,000-$18,000/yr, volume-negotiated) for a correlation engine, data lake tiering, and 24/5 support.
bolt Choose OmniSight if...
- check_circleYou want network-connection visibility that's built into the agent itself — no separate log shippers or sources to wire up.
- check_circleYou want metadata-only collection by design — Graylog's whole purpose is indexing full log content; OmniSight never collects payloads or log bodies.
- check_circleYou don't want to size and operate an Elasticsearch/OpenSearch + MongoDB cluster just to get visibility.
- check_circleYou want dense, purpose-built SOC alert triage out of the box, not a general-purpose log search platform you configure yourself.
Side by Side
| Graylog | OmniSight | |
|---|---|---|
| License / cost model | Graylog Open: free (SSPL license), self-hosted, unlimited log ingestion, no per-user fees; Graylog Enterprise/Security: from ~$15,000-$18,000/yr, volume-negotiated | Licensed monthly plans, self-hosted |
| Deployment shape | Graylog server + Elasticsearch/OpenSearch + MongoDB cluster; log sources (syslog, GELF, Beats, APIs) configured separately per system | Single self-hosted server + lightweight agent with network visibility built in |
| Data scope | General-purpose log ingestion and indexing — full log message content from any source you point at it | Connection metadata only — no payloads, no log content, no file contents |
| Infra footprint | Public estimates: $500-5,000+/mo infrastructure, 20-40 hrs/mo operational labor for self-managed Graylog Open | Runs on modest self-hosted server hardware; no search-cluster to size |
| Setup time | Requires configuring log sources, pipelines, and index sets before you see meaningful data | Minutes — account-gated installer to first event |
| Detection / AI | Graylog 7.1 (Spring 2026): automated investigations, behavioral anomaly detection, Sigma rules from private repos | Built-in and custom detections (e.g., cleartext HTTP, CVE-driven rules) |
| Vulnerability matching | Not a core built-in focus | CVE/NVD matching against software inventory, with raw NVD detail |
| Alert triage UI | Dashboards, search, and case creation across whatever logs you've ingested | Purpose-built dense alert triage: verdicts, assignment, snooze, suppression history |
| Community / maturity | Long-established, widely deployed log management platform with a large community | Newer, narrower-scope product |
Where Graylog Genuinely Wins
- General-purpose log ingestion from virtually any source — not limited to network/endpoint telemetry
- AI-powered automated investigations and behavioral anomaly detection (2026 feature set)
- Horizontal scaling and an API-first architecture that plugs into an existing toolchain
- A free, unlimited self-hosted tier (Graylog Open) with an optional enterprise upgrade path
Where OmniSight Genuinely Wins
- Network visibility built into the agent itself — nothing to configure or ship separately
- Metadata-only by design — never indexes log content or payloads, unlike a platform whose core job is exactly that
- No Elasticsearch/OpenSearch + MongoDB cluster to size, patch, or operate
- Minutes to first event, plus dense SOC alert triage out of the box
Frequently Asked Questions
Is Graylog free?
Yes — Graylog Open is free and self-hosted with unlimited log ingestion under the SSPL license. Graylog Enterprise/Security adds paid features (correlation engine, data lake tiering, 24/5 support) starting around $15,000-$18,000/year.
Is OmniSight a Graylog alternative?
Not directly — Graylog is a general-purpose log management/SIEM platform, while OmniSight is a purpose-built, metadata-only network visibility and SOC triage console. Teams that specifically want network visibility without standing up a log pipeline may prefer OmniSight.
Does OmniSight replace Graylog?
No. If you need to centralize and search logs from many different systems and sources, Graylog's scope is broader. OmniSight doesn't ingest or index general log content at all — metadata-only, by design.
Can I run both?
Yes — some teams send application/system logs to Graylog for general search and correlation, while using OmniSight specifically for lightweight, always-on network-connection visibility and SOC triage.
