Modern identity and authentication security for the infrastructure you already run.
AuthNull helps organizations secure access to on-premises infrastructure through modern MFA, identity-based authentication, and Zero Trust security principles, protecting users, administrators, service accounts, servers, applications, databases, and network resources without replacing the infrastructure they already rely on.
On-premises access still runs on passwords and perimeters.
Traditional on-premises environments often rely on passwords, disconnected authentication systems, and perimeter-based security — making it difficult to consistently verify identity across servers, applications, remote access systems, and network infrastructure.
Password-based access remains vulnerable to phishing, theft, and reuse.
Many on-premises systems, including Active Directory, RADIUS, and databases, were not designed for modern MFA.
Legacy infrastructure needs stronger authentication without forcing organizations to replace existing systems.
Users and administrators may have excessive access.
VPN, RDP, SSH, database, and network access can create large attack surfaces.
Security teams need better control and visibility over authentication events.
AuthNull acts as an identity and authentication layer for existing infrastructure.
It helps organizations protect what they already run:
Active Directory MFA
Protect Active Directory users and authentication workflows with an additional MFA step and centralized policy enforcement.
RADIUS MFA
Secure VPNs, network devices, and other RADIUS-enabled systems with stronger authentication.
Database MFA
Protect database users and administrative access with MFA and database-specific access policies.
Application MFA
Add stronger authentication to connected applications and services.
Agentless Authentication
Extend authentication controls to existing infrastructure without installing agents on every protected system.
Zero Trust Access
Evaluate access based on identity, context, and policy rather than network location alone.
RDP and SSH Protection
Secure remote desktop and command-line access to servers and infrastructure.
Service Account Security
Improve protection for service accounts and other non-human identities used by applications and workloads.
Built for the environments most platforms skip.
Designed specifically for on-premises infrastructure
purpose-builtMany identity platforms are designed primarily for cloud environments. AuthNull is built for the servers, directories, and network systems organizations already operate.
Agentless approach reduces deployment complexity
lower deployment overheadSecure existing systems without requiring agents across every server, endpoint, or network device.
Supports existing enterprise protocols and systems
interoperableActive Directory, RADIUS, VPN, databases, RDP, SSH, and service accounts — the standards your estate already speaks.
Brings MFA and Zero Trust where they weren't native
legacy-readyBring modern MFA and Zero Trust controls to environments that may not support them natively, without requiring a complete infrastructure redesign.
Strengthens security without disrupting operations
designed for low disruptionStronger access control designed to fit existing operations and reduce disruption to the business.
Where we are, and where we're going.
Our mission is to make strong, identity-based security practical for every organization operating on-premises infrastructure. AuthNull helps organizations improve security without forcing them to replace the systems and protocols they already depend on.
How we build, and what we hold to.
Identity First
Access should be based on verified identity, not network location alone.
Security by Design
Security should be part of every authentication flow, integration, and access decision.
Practical Zero Trust
Zero Trust should work with real-world infrastructure, including existing and legacy systems.
Simplicity
Security should be straightforward to deploy, manage, and use.
Interoperability
AuthNull should work with existing systems, protocols, and infrastructure.
Secure Every Identity
Users, administrators, service accounts, applications, and workloads all require appropriate protection.
Continuous Improvement
Security threats evolve, so authentication and access controls must continue to improve.
These principles shape every access decision we ship.
Secure your on-premises infrastructure with stronger authentication and identity-based access controls.
