THE CHALLENGE
Authentication Isn't Trust.
Every Device Must
Earn Network Access.
Modern enterprise networks extend beyond managed corporate devices. Employees, contractors, guests, BYOD endpoints, and IoT systems connect continuously, making network access one of the largest attack surfaces.
-
New devices connect every day.
-
Device ownership changes.
-
Endpoint compliance drifts over time.
-
Unauthorized devices attempt access.
-
Manual network configurations bypass policies.
-
Legacy access controls struggle to adapt.
Granting access based solely on credentials is no longer enough.
AVA continuously validates user identity, device ownership, manufacturer, operating platform, and endpoint security posture before authorizing network access-enforcing trust before connectivity.
Secure Every Connection Before
It Becomes Trusted
Every device connecting to your network introduces a potential security risk. Trusting users based solely on successful authentication or network connectivity is no longer enough.
Underscore’s Access validation and authorization (AVA) ensures that every connection is evaluated against organizational security policies before access is granted. By validating both the user and the device, AVA helps organizations prevent unauthorized access, simplify network operations, and strengthen enterprise security.
Identity
Validation
Authenticate users before granting access using secure, policy-driven workflows.
Policy-Based
Authorization
Automatically enforce organizational access policies based on user identity, device compliance, and predefined security rules.
Device Trust
Verification
Validate device ownership, manufacturer, operating platform, and security posture before network authorization.
Continuous Network
Protection
Monitor network access continuously to identify unauthorized devices and maintain policy compliance throughout the device lifecycle.
IDENTIFY. VERIFY. CONNECT.
Underscore's Access Validation & Authorization (AVA) combines identity-driven access control, device trust verification, endpoint security posture assessment, and integrated DHCP, DNS & IPAM services to ensure only authenticated users operating trusted and compliant devices gain access to enterprise resources.
Connect Users connect to the enterprise network through wired or wireless infrastructure.
Validate AVA authenticates users and evaluates device identity, ownership, platform, and endpoint security posture.
Authorize Compliant devices are granted appropriate network access based on organizational policies, while unknown or non-compliant devices remain isolated.
Protect Integrated DHCP, DNS, and IPAM services enforce secure communication, policy controls, and continuous visibility across the network.
Key Capabilities
Identity-Driven Access Control
Grant network access only after verifying user identity and organizational policies.
Integrated DHCP, DNS & IPAM
Simplify network management through centralized IP allocation, DNS services, and address visibility.
Clientless Device Validation
Validate endpoint security without deploying heavyweight endpoint agents.
Static IP Bypass Prevention
Prevent users from bypassing onboarding workflows through manual IP configuration.
Centralized Policy Management
Manage authorization policies across distributed enterprise environments from a single console.
Device Security Validation
Evaluate endpoint compliance before authorizing access to enterprise resources.
Captive Portal Authentication
Provide secure onboarding for employees, contractors, guests, and unmanaged devices.
Device Identity Verification
Identify randomized MAC addresses and maintain trusted device identities across the enterprise.
DNS Security Enforcement
Apply category-based filtering, malicious domain blocking, and DNS security policies for every authorized connection.
