What it sells: Graylog

What Graylog Enterprise does[3][5][6]
Graylog Enterprise is for operations teams needing enterprise-grade log management and compliance. It runs cloud-native, on-premises, or hybrid with full feature parity across every deployment model. It includes a built-in data lake that stores years of logs on AWS or Azure Blob without counting against the license.
What Graylog Security does[3][6]
Graylog Security is for lean security teams needing security information and event management (SIEM). A single Graylog Consumption Unit can be redeemed for 20 GB of Graylog Security.

What it sells: Kai

What Kai Autonomous Defense Platform does[4][13]
The Kai Autonomous Defense Platform executes the exposure lifecycle end to end without human handoffs. Kai aggregates findings from existing security and IT systems, determines reachability and exploitability, discards what cannot be exploited, attaches evidence to what survives, and then remediates. Kai agents interrogate CMDB, endpoint, cloud, identity, scanning, and code systems, then rebuild each asset record from the evidence they find.
What Continuous Threat Exposure Management (CTEM) does[7]
Kai runs all five phases, then adds two more: it executes the assigned fix immediately, and it watches exposed assets with targeted detection rules until remediated. Auto-remediation sits at phase six, where Kai takes immediate action once a fix is assigned.
What Kai Watch does[7]
Kai Watch continuously monitors telemetry to identify active exploitation. Kai Watch deploys validated detection rules to contain risk across the environment while fixes are in progress. Kai Watch is part of the detection phase, which Kai places at phase seven once remediation is underway.
What AI-native SAST does[15]
Kai is releasing an AI-native SAST capability in preview for select customers. Kai applies AI-native reachability analysis from the start, combining static analysis with runtime behavior to determine whether a finding is actually exploitable before it reaches a human. Kai validated each finding by automatically generating exploits and running them in an out-of-band non-production environment.

About Graylog

Graylog sells SIEM and log management. Graylog started in 2009 as an open source log management project and evolved through user feedback to a SIEM on the same codebase. Graylog says its platform is built for the people covering security, IT, and audit, as one platform at a cost of ownership that makes sense.[6]

Graylog describes a cost problem in which teams drop data at the edge to keep the bill down, balancing against compliance requirements. Graylog also points to legacy tools that take a full-time admin before they return a single answer. Graylog Enterprise is described as giving IT teams full visibility and operational control without the complexity, cost, or months of setup.[5][6]

Graylog sells its platform in editions. Graylog Enterprise is for operations teams needing enterprise-grade log management and compliance. Graylog Security is for lean security teams needing security information and event management (SIEM).[6]

On the security side, Graylog says alerts pointing at the same thing become a single incident, weighted by what that asset is worth to you and other risk amplifiers. Graylog provides pre-built content for common sources, attack frameworks, and the standards customers are audited against. Graylog also offers a report writing AI agent that drafts the documentation of what happened and what needs fixing. Graylog supports watchlists, which are managed lists of values that Graylog checks log messages against.[7]

On the operations side, Graylog collects evidence from across an environment on one timeline with consistent field names. Graylog Enterprise includes a built-in data lake that stores years of logs on AWS or Azure Blob without counting against the license. Graylog Enterprise offers MCP server integration that connects Graylog with a preferred LLM for AI-assisted analysis and automation. Graylog says tiering and policy-driven retention satisfy an audit without keeping everything in expensive storage.[5]

Graylog Enterprise runs cloud-native, on-premises, or hybrid with full feature parity across every deployment model. Graylog says self-managed deployment gives full control over where data lives but requires the customer to provide the infrastructure and maintain uptime. Graylog Cloud is available in the AWS Marketplace. For data residency, Graylog says EU-based OVH and Secunet bring data sovereignty to tiered storage for GDPR and DORA requirements.[5][6]

Graylog licenses processed data volume in the active data tier, with daily volume and annual consumption as the two models. Annual consumption is measured in Graylog Consumption Units, and a single unit can be redeemed for 20 GB of Graylog Security or 25 GB of Graylog Enterprise.[1][6]
