Quick Snapshot

A skimmable look at capabilities. Each point is expanded below with examples from real-world remote work and hybrid office setups.

Why Perimeter 81 Stands Out

Many “business VPNs” are a thin client plus a few admin toggles. Perimeter 81 goes further with a unified SASE approach: Zero Trust Network Access for private apps, Secure Web Gateway for outbound protection, and Firewall-as-a-Service to enforce policy in the cloud—no legacy hardware cycles. Admins model access around users, devices, and apps rather than IPs and subnets.

The visual network builder, quick site-to-site tunnels, and identity provider integrations (SSO/MFA) help security teams move fast. Granular rules allow just-enough access (least privilege) with simple rollbacks when audits demand changes.

• Zero Trust by default: segment access per app and user group.
• Cloud-delivered security: SWG + FWaaS block risky domains, categories, and threats.
• Global backbone: PoPs designed for remote work—fast handshakes and stable throughput.
• Fast deployment: plug into AWS/Azure/GCP and on-prem firewalls; publish internal apps privately.
• Auditability: robust logging and reporting for compliance and investigations.

Performance: Speed and Stability

In daily use, the client connects quickly and stays connected while roaming between home Wi-Fi, office Ethernet, and mobile hotspots. Latency remains predictable when you choose nearby gateways, and long-haul sessions are stable enough for screen shares and SSH. Developers pulling containers and repos won’t feel throttled by policy enforcement when rules are tuned sensibly.

For hybrid environments, site-to-site tunnels keep on-prem resources reachable without exposing entire subnets. Browser-based app portals reduce “full tunnel” use, improving throughput on SaaS while keeping private apps gated behind device + identity checks.

Privacy and Security

Policies are enforced in the cloud, with per-app ZTNA, URL/DNS filtering, TLS inspection options (per policy), and a kill-switch behavior at the OS level. Device posture and group-based policies ensure that unmanaged or non-compliant machines can’t reach sensitive apps. Logs stream to SIEMs for long-term retention and correlation.

The security model favors least privilege. Instead of “VPN to the whole office,” admins define which users can reach which apps over which ports, and pair those rules with MFA and conditional checks. Result: smaller blast radius and clearer audits.

Streaming and Access

Perimeter 81 isn’t built for entertainment unblocking, and consumer streaming behavior isn’t a design target. Some services may work, but the value proposition is securing business traffic and private resources at scale. If unblocking media is your goal, compare a consumer-focused provider instead.

Devices and Ease of Use

Clients are available for Windows, macOS, iOS, Android, and Linux (via standard configs). Staff see a simple connect button and a short list of recommended gateways or app tiles. Admins can silently deploy and pre-configure profiles using MDM tooling.

• Desktop: Windows, macOS, Linux
• Mobile: iOS & Android with auto-connect and biometrics
• Identity: SSO/MFA (Okta, Azure AD, Google Workspace, etc.)
• Integrations: SIEM logging, API, and webhooks for automation

Support and Overall Value

The documentation and onboarding flows are designed for real IT constraints—short setup windows, distributed teams, and changing app maps. Because policy lives in the cloud, updates roll out fast without touching legacy appliances. For organizations maturing from “one big VPN,” Perimeter 81 offers a clear step into Zero Trust with measurable wins in visibility and control.

If your needs are consumer streaming or hobby VPN use, you’re overbuying. But if you must reduce attack surface, gate private apps, and keep contractors segmented, this platform justifies the spend—and the admin hours you’ll save.
