Description
The complexity of application security is on the rise, but Barracuda simplifies it. The Barracuda Web Application Firewall is a key component of the Barracuda Cloud Application Protection platform, which integrates a wide array of complementary solutions and features aimed at providing thorough application security. This firewall shields applications, APIs, and mobile app backends from numerous threats, including the OWASP Top 10 vulnerabilities, zero-day exploits, data breaches, and application-layer denial of service (DoS) attacks. With a blend of signature-based policies, positive security measures, and advanced anomaly detection, the Barracuda Web Application Firewall effectively counters even the most intricate attacks targeting web applications today. Additionally, the Barracuda Active DDoS Prevention service, available as an enhancement to the Web Application Firewall, proactively filters out volumetric DDoS attacks before they can impact your network and compromise your applications. This multi-layered approach not only fortifies security but also enhances the overall resilience of your digital infrastructure.
Description
CacheGuard-OS is an open-source Linux-based UTM gateway appliance OS that has been in active development since 2002. It is designed to run on commodity x86 hardware and act as the default route between an internal network and the internet, replacing the ISP-provided router as the traffic checkpoint.
The stack integrates: Squid (web cache and proxy), ClamAV (web antivirus), ModSecurity (WAF), StrongSwan (IPsec/IKEv2 VPN), IPRoute2 (QoS and WAN load balancing), NetFilter (stateful firewall), SSL inspection, and URL filtering. All components are configured through a web-based admin interface rather than directly, making the platform accessible to operators without deep Linux expertise while remaining auditable by those who want to inspect the underlying configuration.
The OS has been open-source since its first release — source ships on every installed appliance. It was recently published publicly on GitHub to make the codebase easier to browse and audit.
Target deployments are small to medium networks — SMBs, schools, and branch offices — where a commercial UTM appliance is overkill on budget but the threat surface is the same. Runs on bare metal or common hypervisors (VMware, VirtualBox, KVM, Hyper-V). No vendor lock-in, no subscription, no licence cost.
