Simply secure
Kubernetes

For security-conscious enterprises running Kubernetes on bare metal or at the edge.

Kubernetes is not secure by default.

Kubernetes logo

The dynamic and distributed nature of Kubernetes environments, combined with constantly changing components, inherently introduces new security risks. Default configurations often lack the stringent security controls needed to protect across bare metal and edge. The attack surface of Kubernetes can be broad, necessitating security measures at every layer.

Minimal by design, secure by default.

Talos Linux is your immutable OS for Kubernetes, built from the ground up for absolute minimalism. Omni is the purpose-built, API-driven orchestrator for Talos Linux and Kubernetes. Never worry about configuration drift with a declarative, predictable infrastructure unlike any general Linux distro.

With Talos Linux and Omni, you get the most secure Kubernetes foundation, designed to simplify operations and protect your infrastructure.

Smallest attack surface

Talos Linux ships with <50 binaries, with no SSH or shell to introduce drift. Omni environments have the smallest attack surface across data center, edge, and cloud.

Fewest CVEs

Talos Linux has 0 critical CVEs. Flatcar has 27 and Ubuntu 280. Omni builds on this foundation to deliver secure, reliable cluster management everywhere. See our September 2025 analysis.

End-to-end encryption

Omni automates the generation, distribution, and rotation of all critical system and API secrets, freeing operators from manual management for enhanced data privacy,security, and greater regulatory protection.

Zero trust networking

Omni facilitates authenticated, encrypted, and mesh-based communication between Talos Linux immutable and API-driven clusters for stronger privacy and data confidentiality.

Certified security,
built into your infrastructure

Our certifiably secure operations make it easier to meet requirements, satisfy auditors, and stay secure.

SOC 2 Type II
certification

Our processes and controls meet the standards defined by the AICPA. That means faster procurement, smoother onboarding, and easier compliance reviews for your team.

FIPS 140-3
compliant OS

Talos Linux delivers a FIPS-validated build, meeting US government cryptography standards (NIST). Whether you operate in federal, defense, or highly regulated industries, you get a secure, compliant foundation for Kubernetes.

SBOM
support

Talos Linux generates and ships a full Software Bill of Materials for every release. You gain visibility into dependencies, simplify vulnerability management, and provide auditors with the transparency they expect

Features that keep you secure, not busy

Talos Linux and Omni give you the features you need for a secure, consistent Kubernetes infrastructure.

Air-gapped Kubernetes
Run clusters securely and reliably without internet access. With support for internal registries and pre-seeded installation media, you maintain full control over your environment, meet regulatory requirements, and ensure operations continue even in isolated or highly restricted networks.
Kernel hardening
 with KSPP defaults
Out-of-the-box alignment with Linux Kernel Self-Protection Project standards delivers stronger memory protection, blocks unprivileged BPF, and prevents common attack vectors. Security by default with automatic safeguards that block attacks and protects your infrastructure for a more secure, resilient Kubernetes foundation.
Trusted
Boot
Verifies every boot with signed, read-only images and Unified Kernel Images (UKI), creating a predictable, tamper-resistant state anchored by TPM. This ensures a predictable, tamper-resistant system state, giving you stronger security and confidence in your Kubernetes foundation.
Pod Security Admission
(PSA) by default
Enforces Kubernetes baseline policies automatically, blocking insecure workloads and protecting your nodes. Stronger security without extra or manual configuration.
Kernel module
signing
Guaranteed kernel integrity allowing only cryptographically trusted and signed modules, blocking tampered or unverified code and protecting runtime integrity at the system’s most vulnerable layer.
OIDC and
SAML authentication
Standards-based identity and access management that enables centralized, secure login across Kubernetes clusters and Talos Linux.
Audit
logging
Automatically records every action in Omni, giving you full visibility, accountability, and compliance reporting without any extra setup.
Encrypted connectivity with WireGuard
End-to-end cluster traffic protection using encrypted WireGuard tunnels and default firewall rules via SideroLink, delivering secure communication without added complexity.
