Zero-Day Threat Protection

The case of Netscaler Gateway and zero-day attacks

Netscaler Gateway, a key element of many companies’ IT infrastructure, is exposed to significant risk during zero-day periods. These vulnerabilities, which arise when new security vulnerabilities are identified and have not yet been patched, leave organizations vulnerable to potential cyberattacks. Secfense’s response to these threats includes, among others: a Full Site Protection (FSP) solution that protects Netscaler Gateway against these types of threats.

Zero day and security vulnerabilities

Key Features and Benefits


Innovative network differentiation

FSP distinguishes between trusted and untrusted networks, offering VPN-like security without the need to invest in a VPN. Full Site Protection is crucial for protecting internal resources in the event of critical zero-day vulnerabilities because it prevents access to the login screen for all unauthorized users on the Internet and limits access to the website only to those who are authorized to do so.

Protection from unauthorized access

By making Netscaler Gateway invisible to automated Internet scans and unauthorized users, FSP protects the system from attack during the vulnerable phase, between the detection and patching of vulnerabilities. It not only secures the login screen with strong, phishing-resistant authentication based on the FIDO standard but also prevents unauthorized persons from viewing the website.


Quick implementation

Both User Access Security Broker and Full Site Protection can be quickly implemented in various applications without interfering with their code, allowing for immediate improvements in security measures without the need to make extensive changes to the system.


Enhanced authentication measures

FSP and Secfense broker require the user to use a second factor of authentication on a trusted network, ensuring that only authorized personnel can access the system from external locations. This two-layer protection is particularly effective in mitigating risk during zero-day periods.


Administrative control and flexibility

FSP gives security administrators complete control over the authentication process and the flexibility to apply different security policies to different applications. This adaptability is crucial for quickly responding to emerging threats.
