LayerV vs Traditional VPNs
Infrastructure Invisibility vs Encrypted Tunnels
VPNs have been the standard for remote access for decades. They create encrypted tunnels between users and corporate networks. But VPNs have a fundamental limitation: they encrypt traffic to servers that are still visible and scannable on the internet. LayerV eliminates this by making servers invisible.
Architectural Difference
VPNs work by creating an encrypted tunnel between a client and a VPN concentrator. Traffic flowing through the tunnel is encrypted and secure. However, the VPN concentrator itself must be publicly accessible — it has a public IP, open ports (typically UDP 500, 4500 for IPsec or TCP 443 for SSL VPN), and responds to connection attempts. This creates several problems: - **VPN endpoints are high-value targets**: Attackers know where they are and actively exploit VPN vulnerabilities (Pulse Secure CVE-2021-22893, Fortinet CVE-2023-27997, Cisco CVE-2023-20269) - **Broad network access**: Once authenticated, VPN users typically have access to the entire network segment, enabling lateral movement - **Credential replay**: Stolen VPN credentials can be used from anywhere - **Always-on presence**: VPN endpoints are permanently visible and scannable LayerV inverts this model. There are no visible endpoints to scan, no concentrators to exploit, and no broad network access. Each resource access is independently authenticated, scoped to a single resource, and automatically expires.
Feature Comparison
| Feature | LayerV | Traditional VPNs |
|---|---|---|
| Server visibility | Invisible — zero network presence | Visible — VPN concentrators have public IPs and open ports |
| Attack surface | Zero — nothing to scan or exploit | VPN endpoints are high-value targets with known CVEs |
| Access scope | Per-resource, per-session, time-limited | Broad network segment access |
| Lateral movement | Impossible — each resource access is isolated | Common risk — authenticated users access the full network |
| Credential theft impact | Minimal — QURLs are ephemeral and identity-bound | Severe — stolen credentials grant broad, persistent access |
| Client software | Agentless for web resources | Requires VPN client on every device |
| Split tunneling | Not applicable — only accessed resources are involved | Configuration headache — all-or-nothing traffic routing |
| Performance impact | < 50ms authentication, then direct traffic | All traffic routed through VPN — bandwidth bottleneck |
When to Choose
Choose Traditional VPNs
Choose a traditional VPN if you need to route all traffic through a corporate network for compliance monitoring, if your organization has legacy systems that require network-layer access from specific IP ranges, or if you need a simple, well-understood solution for a small team with low security requirements.
Choose LayerV
Choose LayerV if you want to eliminate the attack surface that VPNs create. LayerV is the better choice when your VPN concentrators have been targeted, when you need per-resource access control instead of broad network access, when you want to eliminate lateral movement risk, or when you're tired of managing VPN client software on every device. LayerV is also the right choice for organizations modernizing their security posture — VPNs are a 1990s solution to a 2020s problem.
Frequently Asked Questions
Is LayerV a VPN?
No. VPNs encrypt traffic between a client and a visible server. LayerV makes servers invisible. VPNs protect data in transit; LayerV prevents the server from being found in the first place. These are fundamentally different security models.
Can LayerV replace our VPN?
For most remote access use cases, yes. If you use a VPN primarily to give employees access to internal applications, admin panels, or cloud infrastructure, LayerV provides better security (invisible infrastructure, per-resource access, automatic expiration) without the VPN client headache. If you need to route all traffic through a corporate network for compliance, a VPN may still be needed for that specific requirement.
Why are VPN vulnerabilities so dangerous?
VPN concentrators are always visible on the internet and grant broad network access when compromised. This makes them the highest-value target on most corporate networks. Recent CVEs in Pulse Secure, Fortinet, and Cisco VPNs have been exploited at scale by ransomware groups. LayerV eliminates this risk entirely — there is no visible endpoint to exploit.
Does LayerV require a client app like VPNs do?
No. LayerV's proxy mode is completely agentless — users authenticate via their browser and identity provider. No VPN client to install, configure, or troubleshoot. An optional lightweight agent is available for SSH and non-HTTP protocols.
