Compare · STACK Vault vs. Astrix Security

NHI specialist vs. the full AI security platform.

Astrix pioneered non-human identity security and is excellent at it. STACK Vault treats NHI as one layer of a broader AI security platform — also covering runtime LLM defense, agent governance, and compliance — with MSP multi-tenancy and SMB-friendly sizing.

At a Glance

What each one is built for

STACK Vault

Full AI security platform. NHI and AI agent identity (Vault), runtime defense (Shield), agent governance (Conductor), compliance evidence (Compli). Multi-tenant for MSP, right-sized for SMB, scalable to enterprise.

Astrix Security

Pure-play non-human identity governance. Deep posture on tokens, service accounts, OAuth grants, and machine identities. Strong category leader if NHI is the single problem you are solving.

Together

You can run Astrix for NHI inventory and posture while STACK Vault handles runtime defense and compliance. Or consolidate into STACK Vault if you want one platform.

Side by Side

Where each one wins

NHI inventory & posture depth

Astrix leads at NHI-specific discovery, scoring, and remediation playbooks across SaaS, IaaS, and PaaS surface area.

Runtime LLM defense

STACK Vault. Astrix does not cover LLM runtime threats. STACK Shield handles prompt injection, jailbreaks, and indirect attacks at the request boundary.

AI-framework compliance

STACK Vault + Compli. Signed evidence for NIST AI RMF, ISO 42001, EU AI Act, SOC 2. Astrix focuses on IAM-style posture, not AI-framework evidence.

MSP multi-tenant

STACK Vault. Tenant-isolated workspaces, per-tenant billing, MSP partner program. Astrix is built for in-house identity teams.

FAQ

Common questions

We just need NHI. Should we just buy Astrix?

Probably — if NHI is the only thing on the list. Astrix has been in the category longest and the depth shows. Consider STACK Vault when the next thing on the list is runtime defense, agent governance, or AI-specific compliance.

Does STACK Vault cover the same NHI ground as Astrix?

STACK Vault's NHI layer is good and getting better, but Astrix has more depth on legacy NHI surfaces (older SaaS, service accounts, OAuth grants). STACK Vault's NHI is built for the AI-agent era specifically.

We are an MSP. How does Astrix handle multi-tenant?

Astrix is built for in-house teams. STACK Vault has multi-tenant workspaces and MSP console from day one.

What about agentic AI specifically?

STACK Vault's Conductor + Shield + Vault stack is purpose-built for the agent era — verifiable identity, capability scoping, loop detection, signed audit. Astrix does not focus there.
