CloudSlash / Security

Security by Architecture

Read-only hosted observation, Ed25519-signed remediation plans, and AES-256-GCM credential encryption.

Effective November 2026 · support@devilabs.dev ↗

01

Read-only SaaS

Horizon never directly mutates or deletes live production systems.

02

Signed S.A.U. plans

Remediation plans are cryptographically signed with Ed25519.

03

Tenant isolation

Strict organization-scoped access controls and encrypted secrets.

1. Read-only control plane

CloudSlash separates observation from execution. Horizon SaaS connects to your systems using strictly read-only credentials or ingested CLI snapshots. When your team approves an optimization, Horizon compiles an ephemeral, Ed25519-signed S.A.U. plan that your engineers execute in their own environment. Once executed, the plan becomes an immutable audit record.

2. Encryption & tenant isolation

All network communication uses TLS 1.2/1.3. Source connection credentials and BYOK model keys are encrypted at rest using envelope AES-256-GCM encryption. Every API request is authenticated via short-lived JWTs and scoped to your organization ID.

3. Plugin verification

CLI plugins validate SHA-256 binary checksums and manifest signatures prior to local execution. Hosted gRPC plugins require explicit operator endpoint approval before they can be added to a Horizon workspace.

4. Responsible vulnerability disclosure

If you discover a potential security vulnerability, please email support@devilabs.dev with reproduction details and affected endpoints. We acknowledge reports promptly and coordinate remediation prior to public disclosure.
