NACIO

NACIO is a network access control platform for organizations that need authentication, endpoint checks, profiling, and guest access in one deployment. It is best suited to infrastructure teams managing mixed wired, wireless, VPN, BYOD, or IoT environments across more than one site. The pre-release stage makes early-access support valuable, but buyers must be comfortable evaluating a product before general availability.

Overview

NACIO combines 802.1X RADIUS authentication with policy checks on Windows and macOS endpoints. It can be self-hosted on customer infrastructure or consumed as a cloud-hosted service, giving organizations a choice between operating the platform themselves and outsourcing its hosting.

Its scope extends beyond login control. NACIO profiles devices, discovers unmanaged equipment, enforces compliance conditions, issues certificates, and provides captive portals for guests. That breadth makes it a candidate for campuses, hospitality venues, healthcare networks, OT and IoT deployments, BYOD programs, and managed service providers. However, it remains in pre-release, so organizations seeking a mature, broadly proven product may prefer an established alternative.

Key features

Authentication and identity

The built-in RADIUS service supports EAP-TLS, PEAP-MSCHAPv2, EAP-TTLS, EAP-FAST, and CHAP across wired 802.1X, wireless, and VPN access. Identity sources include Active Directory, Azure AD/Entra ID, Okta, Google Workspace, SAML 2.0, LDAP/LDAPS, RADIUS proxy, and a local NACIO user database. This range can accommodate organizations with established directory services or multiple identity systems without limiting access control to one provider.

Endpoint compliance and certificates

Windows and macOS agents can check patch level, antivirus, disk encryption, firewall status, and custom rules before access is granted. Those checks let administrators make network admission conditional on device posture, although endpoint enforcement is centered on the two listed desktop platforms. An internal certificate authority issues and manages machine and user certificates, with agent deployment for Windows and macOS, supporting certificate-based authentication without a separate certificate-management product.

Profiling, discovery, and guests

Device profiling uses DHCP fingerprints, HTTP user-agent data, and network behavior analysis. Active and passive scanning maps IP ranges, resolves hostnames, fingerprints ports and services, and flags rogue or unmanaged devices, giving teams visibility beyond devices that authenticate normally.

Captive portals support sponsor approval, SMS or email verification, social login, and time-limited access. That combination fits visitor networks and venues where temporary access and approval workflows matter.

Resilience and network integration

NACIO works with RADIUS-capable switches, access points, and firewalls, including equipment from Cisco, Aruba, Juniper, Ubiquiti, Fortinet, and Palo Alto. Remote agents use encrypted tunnels, while remote probes do not require a VPN or open firewall ports. Active-passive high availability synchronizes sessions, leases, and endpoint records and can fail over automatically, reducing the operational impact of a node outage.

Pricing

NACIO uses custom pricing, with quotes provided on request. Licensing is based on perpetual per-device licenses tied to a major version, with optional upgrades to the next major version. That structure may suit organizations that prefer ownership over recurring subscriptions, but the eventual cost depends on device count and upgrade choices, so budgeting requires a direct quote.

The product is currently in pre-release. Early-access customers receive dedicated onboarding support and a direct line to the engineering team, which is useful when deployment procedures and integrations still need close guidance. There is no published free plan or trial term to lower the commitment for evaluators.

Platforms

NACIO supports macOS and Windows, and can be deployed as self-hosted software or as a cloud-hosted service. Its network role covers wired, wireless, and VPN access, with a hybrid deployment model that can combine customer infrastructure and hosted components.

Who it's for

NACIO is aimed at enterprise campuses, BYOD programs, hospitality and venues, OT and IoT networks, healthcare organizations, and managed service providers. It is a strong fit when one control plane must combine 802.1X authentication, posture checks, profiling, guest onboarding, and high availability across equipment from several network vendors.

It is less suitable for a small organization wanting a ready-to-buy, generally available product with transparent pricing or a simple free tier. The pre-release status and quote-based licensing demand more procurement and technical evaluation than those buyers may want.

Pros and cons

Pros

• Broad authentication coverage: Multiple EAP methods and support for wired, wireless, and VPN access cover varied access policies.
• Deep identity integration: Directory, cloud identity, SAML, LDAP, proxy, and local-user options reduce dependence on one identity source.
• Posture-aware admission: Windows and macOS checks for patches, antivirus, encryption, firewall, and custom rules can block noncompliant devices.
• Useful operational visibility: Profiling and active/passive discovery can identify device types, services, and unmanaged equipment.
• Resilient architecture: Active-passive failover with synchronized state supports continuity for critical networks.

Cons

• Pre-release product: Organizations requiring a mature, generally available platform face more deployment uncertainty.
• Custom pricing: Buyers cannot compare a published price or free tier without requesting a quote.
• Per-device major-version licensing: Future major-version upgrades are optional purchases rather than automatically included.
• Endpoint agent scope: Compliance checks are described for Windows and macOS, not other endpoint platforms.

Alternatives

PacketFence is the better choice when an open-source, self-hosted NAC with unlimited devices and full source code is the priority; its GPL v2+ edition also offers free and trial options across a broad platform range.

NACVIEW suits teams wanting a freemium route, including a lifetime NV-20 license limited to 20 simultaneously authorized endpoint devices.

Arista NG Firewall is an option for basic security and connectivity through a free web-based plan with limited capabilities.

SecureW2 Cloud NAC is worth considering when a paid cloud NAC quote is preferred and support for Android, iOS, Linux, macOS, web, and Windows is required.

EasyNAC fits buyers seeking a paid Linux, self-hosted, or Windows appliance with perpetual licensing typically available and subscription options.

Arbiter is appropriate for visibility-only asset discovery, with a 29.00 EUR monthly plan after a 60-day free trial and no access enforcement.

Auconet BICS is another paid, self-hosted option with API support and quote-based purchasing.

Cloudi-Fi Cloud NAC is a paid web-based NAC alternative priced through a contact-form quote.

Verdict

Choose NACIO if you need one NAC platform to combine multi-method RADIUS, endpoint compliance, profiling, certificates, guest portals, and failover across a heterogeneous network. Look elsewhere if pre-release software, quote-only pricing, or per-device major-version licensing makes deployment risk and long-term budgeting unacceptable.
