Perimeter 81 FAQ

How does Perimeter 81 handle access to on-premises resources without a public IP address?

Perimeter 81 uses a software agent that creates a secure tunnel from the on-premises resource to the Perimeter 81 cloud gateway, allowing remote users to access it without exposing the resource to the internet.

Can Perimeter 81 integrate with existing identity providers like Okta or Azure AD?

Yes, Perimeter 81 supports integration with major identity providers for single sign-on (SSO) and user synchronization, enabling identity-aware access policies.

What protocols does Perimeter 81 use for tunneling?

Perimeter 81 uses WireGuard and OpenVPN protocols for secure tunnels, offering high performance and strong encryption.

Does Perimeter 81 support multi-cloud environments?

Yes, it can connect agents across AWS, Azure, GCP, and other cloud providers, allowing unified access control and network segmentation across multiple clouds.

Is there a free trial available for Perimeter 81?

Perimeter 81 offers a free trial for a limited period (typically 7 to 14 days) with full access to its features, after which a paid subscription is required.

How does Perimeter 81 ensure device posture compliance before granting access?

The platform checks device posture criteria such as operating system version, antivirus status, and disk encryption via the agent before allowing access, and can block or restrict access for non-compliant devices.

Can Perimeter 81 be used to segment internal network traffic for Zero Trust?

Yes, it provides network segmentation by creating virtual networks (tunnels) that isolate different resources, preventing lateral movement even if an attacker compromises a user's device.

What is the difference between Perimeter 81's ZTNA and a traditional VPN?

Unlike a traditional VPN that grants access to the entire network, Perimeter 81's ZTNA grants access only to specific applications or resources based on user identity and context, reducing the attack surface and improving security.
