Oasis Security's public positioning centers on full-lifecycle non-human identity (NHI) management: an inventory of machine identities across an enterprise, posture checks on how they are configured, safer secret rotation, and lifecycle management from creation to removal. Oasis is now part of Cyera, which completed its acquisition of Oasis Security on September 3, 2026. Teams researching "Oasis Security alternatives" are usually comparing within the NHI-lifecycle category — Oasis vs Astrix is one such comparison — or discovering that their NHI problem has become agent-shaped, where lifecycle management is necessary but runtime governance of what agents actually do is the more pressing gap. This post covers both. Other vendor-by-vendor guides are collected on the comparison hub.
What Oasis Security's public positioning covers
Per its public site, Oasis frames NHI management as a lifecycle, not a point-in-time inventory: an inventory of every non-human identity with its owner and context, posture checks on identity configurations and on AI agent permissions, threat and anomaly detection, secret rotation, and lifecycle management from creation to removal, with agentic access management for AI agents specifically. That lifecycle framing — as opposed to a discovery-only or posture-only scope — is the core of Oasis's public differentiation, and it is a genuinely harder problem than discovery alone: rotation and decommissioning require write access into the systems that issued the credential, not just read access to inventory it.
Oasis vs Astrix: the most common comparison in this category
Oasis and Astrix Security are often compared because both publicly emphasize discovery and posture assessment across the enterprise NHI estate, and both extend that lens to AI agents. Both are also now part of larger companies: Oasis of Cyera, and Astrix of Cisco — Astrix's site states that it ended standalone sales of new licenses effective June 30, 2026, while existing customers keep the service in their current agreements. Where they may differ in practice is lifecycle depth: how far each platform's automation reaches into actual credential rotation and verified decommissioning versus stopping at discovery, posture scoring, and recommended remediation. That is a legitimate, evaluable difference — and one to verify directly against each vendor's current documentation and a proof-of-concept against your own estate, rather than take on either vendor's marketing claim alone. Our Astrix Security alternatives post covers Astrix's own public positioning and its peer set in more depth.
Oasis vs Microsoft Agent 365 / Entra Agent ID
Oasis has published its own comparison against Microsoft's Agent 365 and Entra Agent ID, positioning itself for hybrid AI-agent governance — organizations running agents across Microsoft and non-Microsoft ecosystems, where an IdP-native identity extension covers the Microsoft estate but not identities issued or used outside it. This is a recurring theme across the NHI and agent-identity category: platform-native identity extensions are strongest inside their own ecosystem, and the cross-platform gap is where third-party NHI platforms position themselves. We cover the general version of this trade-off in Microsoft agent governance and independent control planes.
The broader NHI vendor set
Other vendors whose own sites lead with non-human, workload, or agent identity security include Astrix (Astrix alternatives), Token Security (Token Security alternatives), Aembit (Aembit alternatives), Britive (Britive alternatives), and Entro Security. We cover Entro's secrets-centric angle separately in Entro Security alternatives, since it approaches the same broad NHI problem from a different starting point — secrets and vaults rather than estate-wide identity lifecycle.
What full-lifecycle NHI management does not cover
Discovery, posture, rotation, and decommissioning answer questions about identities that already exist somewhere in your estate: what are they, are they risky, and can we clean them up. They generally do not answer runtime questions about identities acting right now: is this specific action by this specific agent authorized under current policy, can the agent's delegation be scoped down mid-session, and can it be killed in seconds if it starts behaving unexpectedly. That runtime layer is a distinct requirement, covered in more depth in the post on agentic AI security posture management and in the NHI credential lifecycle post, which maps where lifecycle management ends and runtime enforcement begins.
Questions to ask during evaluation
- Does rotation actually write back into the system of record, or does the platform only flag stale credentials for a human to rotate manually? This is the line between automation and a prioritized to-do list.
- What does "decommissioned" verify — that the identity is disabled, or that every credential and grant tied to it has actually stopped working? The two are not the same, and the gap between them is where dormant access survives an offboarding.
- How does the platform handle AI agents specifically, as distinct from service accounts and API keys — do agents get their own discovery and posture category, or are they folded into a generic NHI bucket that misses agent-specific risk like delegated sub-agent credentials?
- What is the remediation workflow when a risky NHI is found — does it integrate with the ticketing or IAM systems you already run, or does it require a separate console?
- Does the platform's scope include identities outside your primary IdP ecosystem, given how much of the modern estate spans multiple clouds and SaaS platforms rather than one vendor's identity fabric?
How the layers compose
| Layer | Answers | Example category |
|---|---|---|
| NHI discovery and posture | What identities exist, and which are risky? | Oasis, Astrix |
| NHI lifecycle automation | Can we rotate their secrets and retire them? | Oasis (per its stated lifecycle scope) |
| Secrets and workload identity infrastructure | Can we reduce standing credentials in the first place? | HashiCorp Vault, cloud-native secrets services |
| Agent runtime governance | Is this specific action, right now, authorized — and can we stop it? | Governance control planes |
Most defensible NHI architectures run more than one layer rather than picking a single vendor to cover the whole stack — a lifecycle platform without a runtime layer can tell you an agent's credential is stale, but not that the agent used it to do something it should not have; a runtime layer without a lifecycle platform can enforce policy on registered agents but has no view into the years of pre-existing service accounts and OAuth grants sitting outside it. Praesidia is one option in the runtime-governance row — an AI agent security and governance control plane covering agent identity and access, guardrails, audit evidence, and cost controls in one place — and it is intentionally positioned to sit alongside an NHI lifecycle platform rather than replace it: Oasis and Astrix answer what exists and whether it is clean; a runtime layer answers what is happening now and whether it is allowed.
Choosing between them
If your NHI problem is estate-wide — years of accumulated service accounts, API keys, and OAuth grants that nobody has fully inventoried — start with an NHI lifecycle platform — Oasis, now part of Cyera, is one — and weigh the rotation-and-decommissioning depth specifically, since that is the harder engineering problem and the clearest differentiator between vendors in this category. If your NHI problem is concentrated in a growing population of AI agents going into production, prioritize the runtime governance layer first — per-agent identity, scoped delegation, and a kill switch — and treat estate-wide legacy cleanup as a parallel, not blocking, workstream. See our identity and access for AI guide for the full category map across both layers.
Common questions
What is Oasis Security known for? Per its public positioning: non-human identity lifecycle management — inventory, posture, secret rotation, and lifecycle management from creation to removal — across enterprise NHIs including AI agents. Oasis is now part of Cyera, which completed its acquisition on September 3, 2026.
Is Oasis or Astrix the better choice? Both publicly emphasize discovery and posture across the enterprise NHI estate; the differentiator to verify directly is lifecycle depth, specifically how far each platform's automation reaches into actual credential rotation and decommissioning versus recommending remediation for a human to execute. Test both against your own estate rather than relying on either vendor's comparison claims, and confirm how each is sold today: Astrix ended standalone sales of new licenses on June 30, 2026, as it moves into Cisco.
How does Oasis compare to Microsoft's Entra Agent ID? Oasis has published its own comparison positioning itself for hybrid AI-agent governance across Microsoft and non-Microsoft ecosystems, where an IdP-native extension is strongest inside its own platform and a third-party NHI platform can cover identities and agents outside it.
Does an NHI lifecycle platform replace agent runtime governance? No. Lifecycle platforms answer what identities exist and whether they are clean; they generally do not authorize individual actions in real time, scope delegation mid-session, or provide an immediate kill path for a misbehaving agent. Agent-heavy estates typically need both.
Where should a team start if budget only covers one layer this year? Sequence by where the risk is growing fastest: legacy-heavy estates with a large accumulated backlog of ungoverned service accounts start with an NHI lifecycle platform; estates where agent count is growing faster than the backlog start with runtime identity and containment, since that is where new ungoverned risk compounds daily.
