Firewall and VPN

A simple firewall for small businesses is essential to protect internet-connected devices from modern cyber threats. Every device connected to the Internet is exposed to risks such as hacking attempts, data theft, and unauthorized access, even when endpoint security tools are in place. Cyber-criminals actively search for vulnerable systems to exploit, often using them to spy on users, steal sensitive information, or launch attacks against third-party networks.

CacheGuard Gateway provides a simple firewall for small businesses that is designed to make network security easy, effective, and accessible without requiring advanced technical expertise. It helps secure internet access by filtering traffic, controlling access, and blocking malicious activity before it reaches your internal network.

In addition to its firewall capabilities, CacheGuard Gateway integrates essential security features such as VPN services and web filtering, offering a complete and lightweight security solution tailored for small business environments.

What is a Simple Firewall for Small Businesses

A Simple Firewall for Small Businesses is a security solution designed to protect a company’s internet access, users, and devices in a way that is easy to deploy, easy to manage, and does not require a dedicated cybersecurity team.

Unlike traditional enterprise firewalls, which are often complex, expensive, and require specialist knowledge, a simple firewall focuses on delivering essential protection with minimal configuration and operational overhead.

Firewall and VPN for Small Businesses

Traditional Firewall

The firewall protects PCs, servers, and other connected devices from hostile intrusions. CacheGuard is based on a stateful packet filtering module and provides Network Address Translation (NAT) and Port Address Translation (PAT). In addition, common network attacks, such as but not limited to DoS, SYN flood, Smurf, Xmas, and IP spoofing, are blocked by default. You can also implement firewall rules based on protocol, IP addresses, ports, and IP attributes.

IPsec VPN (Virtual Private Network)

The VPN allows you to securely connect remote workers to your IT infrastructure or build permanent secure tunnels between sites using IPsec VPN (Virtual Private Network) technology. With IPsec VPN technology, remotely connected machines are authenticated, and the data exchanged between them remains confidential and unchanged.

Integrated PKI

To establish IPsec VPN tunnels between two points, each point must authenticate the other. This authentication can be based on a PSK (Pre-Shared Key) or SSL certificates. To facilitate all operations on SSL certificates, CacheGuard includes a PKI (Public Key Infrastructure). The CA certificate used for SSL inspection can also be managed by the integrated PKI. Additionally, an embedded OCSP server allows for certificate revocation.

CacheGuard Firewall is integrated into our core product, CacheGuard-OS. CacheGuard-OS is an appliance-oriented operating system that transforms a virtual or bare-metal machine into a network appliance.
