Enterprise VPN & Secure Connectivity
4CGuard Enterprise VPN provides high-throughput site-to-site mesh connectivity and secure client-to-site remote access with modern encryption, multi-factor authentication, and zero-trust access controls.
Fragmented Branch Connections & Vulnerable Remote Access
Legacy remote access architectures often rely on slow, complex VPN clients that expose the entire corporate subnet to compromised remote laptops. Site-to-site connections frequently struggle with routing complexity and high overhead.
Remote employees granted over-privileged access to the entire flat network.
High latency and throughput bottlenecks on traditional SSL VPN concentrators.
Complex manual configuration and maintenance of multi-branch mesh tunnels.
Modern Cryptographic Tunnels with Zero-Trust Access
Encrypted tunnels are established using modern IPsec (IKEv2) or WireGuard protocols. Client endpoints authenticate via enterprise MFA and SAML identity providers, with firewall rules restricting access exclusively to authorized server resources.
Client mutual authentication via X.509 certificates, SAML 2.0, or RADIUS with MFA.
Cryptographic session key negotiation (AES-256-GCM, ChaCha20-Poly1305).
Encapsulated packet transmission over hardware-accelerated crypto pipelines.
Decapsulation at the 4CGuard gateway followed by full NGFW security inspection.
Micro-segmented routing to authorized corporate application targets.
Core technical capabilities
Modern Protocol Support (IPsec & WireGuard)
Supports high-speed WireGuard tunnels and standard IPsec IKEv2 for universal compatibility with network equipment.
Hardware crypto acceleration supporting AES-NI and ChaCha20 vector extensions.
Multi-Factor Authentication (MFA) & SAML
Integrates with enterprise identity providers including Microsoft Entra ID, Okta, and Duo for secure multi-factor login.
Supports SAML 2.0 web-based authentication, RADIUS MFA, and TOTP hardware tokens.
Full-Mesh & Hub-and-Spoke Topologies
Easily construct scalable site-to-site VPN networks connecting headquarters, branch offices, and multi-cloud VPCs.
Dynamic route synchronization with BGP and OSPF integration over encrypted tunnels.
Endpoint Posture & Split Tunneling Controls
Enforce split-tunneling policies and verify endpoint security health before permitting internal resource access.
Configurable routing tables and DNS server push for remote clients.
High-Performance, Least-Privilege Remote Access
Provide remote workers and branch offices with blazing fast, secure connectivity without compromising perimeter boundaries.
- Protect corporate data in transit with modern cryptographic ciphers (ChaCha20-Poly1305, AES-256-GCM).
- Prevent lateral attack spread by restricting remote clients to specific ports and services.
- Eliminate remote worker complaints with ultra-low latency WireGuard connections.
- Simplify branch office expansion with zero-touch VPN provisioning.
Real-world use cases
Hybrid Workforce Remote Access
Scenario: Hundreds of remote employees require secure access to internal ERP and code repositories from home networks.
Outcome: 4CGuard provides MFA-authenticated VPN tunnels with strict user-level access permissions.
Multi-Branch Site-to-Site Interconnect
Scenario: A retail organization needs to securely connect 50 regional store locations back to central data centers.
Outcome: Automated IPsec tunnels connect all locations with dynamic failover and centralized policy management.
