Backend Software Engineer - Rust

ARKION PlatformStandard For Executives Built for boards, CIOs, and audit committees Executive Brief A non-technical overview of the NHI governance gap and how Arkion closes it. Built to forward to your board. Compliance Crosswalk DORA, NIS2, ISO 27001:2022, SEC Cyber-Disclosure — mapped to exactly which Arkion capability satisfies each control. Cost of Inaction Translate NHI exposure into dollars. The cost of a credential-related breach measured against the cost of governing one. Trust Center· soon Security architecture, sub-processors, DPA / MSA / BAA templates, attestation roadmap. Built for procurement. Learn Field notes, principles, and the Standard The NHIG Standard Version 1.0 of the Non-Human Identity Governance Standard. Principles, vocabulary, maturity model. Open for comment. Field Notes Regulatory updates, principle additions to the Standard, breach post-mortems. Slow, considered writing from inside the category. AI Agent Governance What it means to govern an AI agent's identity — provisioning, scoping, revoking. Topic explainer. Certificate Lifecycle From issuance through rotation to revocation. The cryptographic primitives Arkion is built on. Identity Registry The single system of record for every non-human identity in your enterprise. Why Now DORA. NIS2. SEC Cyber-Disclosure. The 2024–2026 timeline that turned NHI governance from optional to required. Tools Estimate, scan, and act Risk Estimator Two minutes. Seven questions. A directional estimate of how many non-human identities are operating outside any governance boundary. Discovery Scan A read-only scan of one environment. Every NHI found, named, scored. Delivered to your inbox. No agents installed. Implementation Timeline Day 1 scan. Week 1 findings call. Week 2–3 pilot. Week 4 governed estate. The path from first call to first audit answer.
