Why VPN Matters

Multiple Locations, One Secure Network

Modern businesses operate across multiple work locations with employees and stakeholders accessing critical data continuously. Each access point opens a potential threat vector for hackers. Maintaining secured connectivity to the organisation's network is essential to protect against data breach attempts.

GajShield's Data Security Firewall creates Virtual Private Networks — networks completely isolated from the rest of the internet. VPN extends a private network across public networks, allowing users to send and receive data as if their devices were directly connected to the private network. Site-to-site and remote access methods, with encryption services that allow secure connections to be formed across any link.

Four Connection Modes

Connect Whatever Needs Connecting

Mode 1

Client to Site

Remote workers and road warriors connecting securely back to corporate resources from anywhere.

Mode 2

Site to Site

Geographically separated offices joined into one cohesive corporate network with encrypted tunnels.

Mode 3

Site to Data Centre

Branches connecting securely to centralised data centre resources with high-throughput tunnels.

Mode 4

Site to Cloud

Hybrid deployments connecting on-prem networks to Azure, AWS, GCP workloads securely.

VPN Protocol Support

Three Standards, One Platform

Pick the protocol that matches your security and operational requirements — GajShield supports the full set.

PROTOCOL 01

PPTP

Simple to set up — the main selling point of PPTP. Tunnels form a point-to-point connection over the GRE protocol. Security has been called into question in recent years — strong, but not the most secure option.

PROTOCOL 02

L2TP / IPsec

More secure than PPTP, with more security features. L2TP creates the tunnel, IPsec provides the secure channel — combining the best features of each protocol. Client-to-site VPN connection mode.

PROTOCOL 03

IPsec

Site-to-site VPN. The IPsec suite enables advanced VPN features. Acts at the network layer, protecting and authenticating IP packets between firewalls, routers, the Secure VPN Client, and other IPsec-compliant peers.

VPN with GajShield

Industry Standards, Hardened Implementation

GajShield provides industry-standard IPsec (Site-to-Site), L2TP, and PPTP VPN (Client-to-Site/Remote Access) along with High Availability for IPsec. Strong authentication via RSA SecureID, VASCO tokens, RADIUS, LDAP, and Active Directory (with 2FA) prevents network and communication interception — integrated with UserSense.

Strong emphasis on data encryption and user authentication. GajShield uses DES, 3DES, AES encryption with hash algorithms MD5, SHA1, SHA2. Pre-shared keys and digital certificates for secure authentication. Internet Key Exchange (IKEv1 or IKEv2) sets up Security Associations in the IPsec protocol suite.

Additional security features include IPsec NAT Traversal, Dead Peer Detection, and PFS (Perfect Forward Secrecy) support. IPsec VPN tunnel up/down logs and active VPN user logs let admins monitor IP address, VPN status, and connection type per user.
