Why Businesses Are Moving to Perimeter 81
Traditional VPNs were designed for a different era — when employees sat in one office, connected to one network, and accessed resources through a single perimeter. Today's business reality is fundamentally different. Your team works from home, coffee shops, client sites, and co-working spaces. They use personal devices, cloud applications, and SaaS platforms. The old perimeter-based security model simply doesn't work anymore.
Perimeter 81, now part of the Harmony platform by Check Point, replaces legacy VPNs with Zero Trust Network Access (ZTNA) — a modern approach that authenticates every user, validates every device, and restricts access to only the resources each user needs. The result is a security model that's more effective, easier to manage, and delivers a vastly better user experience than traditional VPNs.
What Is Zero Trust Network Access?
Zero Trust Network Access operates on a simple principle: never trust, always verify. Instead of granting broad network access to authenticated users (as VPNs do), ZTNA provides granular, identity-based access to specific applications and resources.
The key differences between ZTNA and traditional VPN:
- VPN: Authenticate once, get access to the entire network. Users see everything, even resources they don't need
- ZTNA: Authenticate continuously, get access only to approved resources. Users see only what they need — nothing more
This approach dramatically reduces the attack surface. If a user's credentials are compromised, the attacker can only access the specific applications that user is authorized for — not the entire network.
Key Features of Perimeter 81
Perimeter 81 delivers a comprehensive suite of network security capabilities designed for modern businesses:
Zero Trust Network Access
Identity-based access controls that verify users and devices before granting access to specific applications. No more broad network exposure — users connect only to what they need.
Cloud Firewall
A cloud-delivered firewall that protects your network without the cost and complexity of on-premises hardware. Cloud firewall scales automatically with your business and can be managed from a single dashboard.
Secure Web Gateway
Web filtering and malware protection that blocks access to malicious websites and prevents unauthorized data exfiltration. Policies can be customized by user group, location, and application.
Application-Aware Connectivity
Unlike traditional VPNs that create a tunnel to the entire network, Perimeter 81 creates individual tunnels to specific applications. This improves performance, reduces latency, and limits lateral movement for attackers.
Implementing Perimeter 81 in Your Organization
Successful Perimeter 81 implementation requires careful planning and execution. Here's the process UX Genius follows when deploying Perimeter 81 for our clients:
- Discovery and planning: We map your current network architecture, identify all applications and resources, and define access policies by user role
- Infrastructure setup: We configure Perimeter 81 gateways in the cloud or on-premises, depending on where your applications live
- Policy configuration: We define granular access policies that give each user group access to exactly the resources they need
- Client deployment: We roll out the Perimeter 81 client to your users' devices with minimal disruption
- Testing and validation: We verify that all users can access their required resources and that unauthorized access is properly blocked
- Monitoring and optimization: We continuously monitor the deployment for issues and optimize performance over time
Benefits Over Legacy VPN
Businesses that switch from traditional VPNs to Perimeter 81 consistently report significant improvements:
- Faster connections: Users connect to applications directly rather than routing all traffic through a central VPN gateway
- Better user experience: No more dropped connections, slow performance, or frustrating reconnection prompts
- Stronger security: Granular access controls and continuous authentication eliminate the broad network exposure of traditional VPNs
- Simpler management: A single cloud dashboard replaces complex on-premises VPN infrastructure
- Lower costs: Eliminate hardware VPN concentrators and reduce the IT overhead of managing VPN infrastructure
