A FIPS certificate on a vendor's website is a starting point, not a deployment answer. What that certificate actually covers and what it leaves to your team, is what determines whether your observability stack is compliant in production.

A FIPS certificate on a vendor's website does not tell you whether the data path is encrypted end-to-end across the platform. It does not tell you if the container images are signed and verifiable. It does not tell you whether the platform's processes run as root or non-root. It does not tell you how the platform handles credential management for registry access. And it does not tell you whether the platform can be deployed in an air-gapped network where no external connectivity exists.

These are the questions that matter when you move from evaluating a vendor's compliance posture to actually deploying an observability platform in a regulated environment. The certificate is the starting point. The architecture is what makes the deployment compliant.

This guide covers every architecture decision that matters for FIPS 140-3 deployment. If you are a platform engineer, security architect, or ISSO responsible for the observability stack in a federal or regulated environment, this is your reference.

Start with the Cryptographic Module

Before anything else, verify the cryptographic module. Not 'FIPS compatible.' Not 'FIPS mode available.' Validated. Go to NIST's CMVP certificate list and search for your vendor's module by name. You need an active FIPS 140-3 certificate. If the certificate is 140-2, check the validation date. On September 22, 2026, NIST will move all FIPS 140-2 certificates to the Historical List. After that date, FIPS 140-2 validated modules should not be used for new federal systems or procurements.

Kloudfuse uses SafeLogic's CryptoComply module, FIPS 140-3 Certificate #5186. The module is embedded directly in the platform binary. It is not a sidecar, not a proxy, not a JVM configuration flag, and not an OS-level dependency that the deploying team must configure. Core platform cryptographic operations — data in transit between Kloudfuse components, data at rest in the storage layer, authentication tokens, and session management — are implemented using the validated module. The validated algorithms include AES, SHA-2, RSA, ECDSA, HMAC, DRBG, and KDF, all per NIST SP 800-series specifications.

The distinction between an embedded module and a customer-configured module is significant for audits. When an assessor evaluates your observability stack, they check the CMVP certificate number and the module boundary. If the module is embedded in the platform, the certificate applies to the platform. If the module is a JVM library that your team installed and configured, the compliance burden — configuration documentation, ongoing maintenance, version tracking — falls on your organization.

SafeLogic note: SafeLogic's CryptoComply provides drop-in replacements for OpenSSL and BoringSSL that are FIPS 140-3 validated. The cryptographic operations happen inside a validated boundary, not outside it. For federal audits, this means the assessor verifies the certificate number against the CMVP database. The compliance evidence is the certificate, not a configuration file.

Secure the Software Supply Chain

In a regulated environment, you need to verify that the software you deploy is the software the vendor built. No modification in transit. No tampering at the registry layer. No substituted images. This requires signed artifacts and verifiable provenance at every layer of the deployment.

Container image signing

We sign all container images. Before pulling an image from the registry, your deployment pipeline verifies the signature against our public key. If the image has been modified — in transit, at the registry, or through a supply chain compromise — the signature check fails and the image is rejected. This is not an optional hardening step. It is the default workflow for every image, every release, every patch version.

In a federal environment where supply chain integrity is a compliance requirement, unsigned container images represent an unverified dependency in your deployment pipeline. Verifying that the image you pull is the image the vendor built requires cryptographic signing — tagging and versioning alone are not sufficient.

Helm chart signing

The Helm charts that define the Kloudfuse deployment are also signed. The chart is the deployment blueprint: it specifies which images to pull, what configurations to apply, what permissions to grant, and what resources to allocate. A tampered chart could redirect the deployment to unsigned images, open network ports, modify security contexts, or escalate privileges. Chart signing prevents these attack vectors at the point where the deployment is defined, before any container runs.

Credential-free registry access via OIDC federation

Traditional container deployments require stored credentials to pull images from private registries: a username and password, an access token, or a service account key. These credentials are long-lived, typically stored in Kubernetes secrets or configuration files, and become targets for rotation audits and secret management overhead.

Kloudfuse supports OIDC federation for AWS ECR. Your Kubernetes cluster authenticates to the registry using its own identity through the cloud provider's identity system. No stored credentials. No secrets to rotate. No long-lived tokens sitting in deployment manifests. The authentication is federated, short-lived, and tied to the cluster's identity rather than a static credential.

Deploy in Air-Gapped Environments

Some regulated environments do not connect to the public internet at all. Air-gapped networks are common in defense, intelligence, critical infrastructure, and certain healthcare environments. Deploying observability in these environments requires a platform that does not phone home, does not check for updates against external servers, and does not require any outbound network path to function.

Kloudfuse supports air-gapped deployment through internal registry mirroring. The process works as follows: container images and Helm charts are pulled from the public registry through a controlled transfer mechanism — typically a USB device, cross-domain solution, or one-way data diode, depending on the classification level. The images are transferred to an internal container registry inside the air-gapped network. The cryptographic signatures travel with the images and are verified inside the air gap using the public key.

Once the images are in the internal registry, the Helm chart deploys the platform using standard Kubernetes primitives. There is no license server to reach. No telemetry endpoint to call. No update check to perform. The platform operates fully within the network boundary with no outbound connectivity required.

This is not a special deployment mode or an alternative configuration. It is the same deployment with a different registry path. The same signed images. The same validated cryptographic module. The same platform.

Lock Down the Runtime

Non-root container execution

Every Kloudfuse service runs as a non-root user by default. Not because you configure it that way through a post-deployment hardening step. Because that is how the containers ship. Service accounts and security contexts are configurable via Helm values for environments with specific UID/GID requirements, but the default posture is already locked down.

This matters because a container running as root that gets compromised gives the attacker root access on the host node. In a FIPS environment where the platform handles encrypted data at rest, root access to the container could mean access to encryption keys, storage volumes, and the cryptographic module itself. Non-root by default eliminates that path. It is the security posture that DISA STIGs and CIS benchmarks require, and it should be the default, not an option you enable.

Data scrubbing across all telemetry streams

Observability data often contains information that should not be stored: API keys accidentally logged in application output, PII in trace attributes, session tokens in HTTP headers, credentials in error messages. This is especially true for AI workloads, where LLM prompts and model responses may contain user data, internal business logic, or sensitive system information.

Kloudfuse provides data scrubbing across all five telemetry streams: logs, metrics, traces, RUM, and profiles. Sensitive patterns are matched and redacted before data is written to storage. Redaction rules are configurable per stream and per data type. For federal environments, this means sensitive data is removed at the point of ingestion, not after the fact.

Self-ingested audit logging

Every query, every dashboard load, every MCP tool invocation, every API call is logged with duration, caller identity, error status, and response metadata. The audit log is self-ingested into the Kloudfuse data store, which means you query your audit data using the same interface and the same query language you use for infrastructure telemetry.

For federal compliance, this answers the question 'who queried what, when, and from where' without requiring a separate audit infrastructure, a separate retention policy, or a separate access control model. The audit trail lives alongside the operational data, governed by the same FIPS-validated encryption and the same access controls.

Who Owns Security After Deployment?

This is the question that separates deployment architecture from compliance posture. And it is the question that matters most during an ATO review.

With SaaS observability platforms, security responsibility splits between your organization and the vendor. You control who on your team can access the platform. The vendor controls the encryption keys, the storage layer, the patching schedule, the access logging, and the data retention on their infrastructure. If an auditor asks who is responsible for the cryptographic controls on your observability data, the answer points to the vendor. Your evidence is their SOC 2 report, their FedRAMP package, and a shared responsibility matrix that defines the boundary between your obligations and theirs.

With Kloudfuse running in your VPC, the ownership model is different. The platform runs on your infrastructure. Your team controls the Kubernetes cluster, the storage volumes, the network policies, and the encryption configuration. We provide the FIPS-validated cryptographic module, the signed artifacts, the non-root containers, and the audit trail. But the infrastructure — and the data — is yours.

For a federal program manager preparing for an ATO review, this distinction simplifies the compliance narrative considerably. When the assessor asks where your observability data is stored, you point to your VPC. When they ask who manages the encryption keys, you point to your team. When they ask for audit logs, you query your own Kloudfuse instance. There is no third-party data flow to justify. No shared responsibility boundary to negotiate. The compliance story is clean because the architecture is clean.

The Deployment Checklist

For teams deploying observability in a FIPS 140-3 regulated environment, these are the requirements we believe should be verified:

1. Cryptographic module holds an active FIPS 140-3 certificate (not 140-2, not 'in process,' not 'compatible mode')

2. Module is embedded in the platform, not limited to the agent layer or a customer-configured JVM library

3. Container images and Helm charts are cryptographically signed and verifiable

4. Registry access uses OIDC federation or equivalent credential-free mechanism

5. Platform deploys to air-gapped environments using mirrored internal registries

6. All services run as non-root by default, with configurable security contexts

7. Data scrubbing covers all telemetry streams (logs, metrics, traces, RUM, profiles) before storage

8. Audit logging captures all queries, tool invocations, and API calls with caller identity

9. Observability data never leaves the customer's network boundary

10. Security and compliance ownership remains with your organization, not the vendor

If your current observability vendor satisfies all ten, you are in good shape. If they satisfy some but not all, the question is not whether they are working on the rest. The question is whether you will have it before September 21, 2026.

The Architecture Is the Compliance Story

FIPS compliance is not a feature flag. It is an architecture. The cryptographic module is the foundation, but the supply chain, the runtime posture, the data residency, the audit trail, and the ownership model are what make the deployment actually compliant. Most vendors give you the certificate and leave the rest to your team: the deployment architecture, the air-gap support, the artifact signing, the non-root hardening, the scrubbing, the audit infrastructure, the governance clarity.

Kloudfuse 4.0 ships all of this by default. FIPS 140-3 Certificate #5186. Signed images and charts. OIDC federation. Non-root execution. Full audit logging. Data scrubbing across every telemetry stream. Deployed in your VPC, your data, your infrastructure, your keys, your compliance story.

Secure observability is not a feature. It is an architecture.
