Netscaler Gateway: Secfense Full Site Protection Against Zero-Day

Netscaler Gateway: How Secfense Full Site Protection Guards Against Zero-Day and Cyber Threats

One of the critical components of many companies’ IT infrastructure is the Netscaler Gateway, which acts as a gateway to the company’s internal resources. Its importance is undeniable, but so is the awareness of its vulnerability to attacks, especially during zero-day periods.

Zero-Day Problem and Netscaler Gateway Vulnerabilities

Netscaler Gateway, being visible on the Internet, is a natural target for cybercriminals. Zero-day periods, when new gaps are discovered but not yet patched, pose special risks. During this time, between the detection and remediation of the vulnerability, organizations are extremely vulnerable to attacks. Citrix, the provider of the Netscaler Gateway, regularly updates its software, but even a short response time can be enough for criminals to launch a successful attack.

How does Secfense Full Site Protection Strengthen Security?

Secfense Full Site Protection (FSP) offers an innovative solution to this problem. FSP, one of the functionalities of the Secfense broker, allows you to distinguish between trusted and untrusted networks, offering benefits similar to VPN but without needing to purchase it. A key element of FSP is the requirement to activate a second factor of authentication on a trusted network, which is only possible when the user is on company premises. After registering, the user can log in to the application from anywhere, maintaining high security.

Protection Against Unauthorized Access

With FSP, Netscaler Gateway becomes invisible to automated Internet scanning tools and unauthorized users. This ensures that systems remain protected even when a new vulnerability is discovered. IT teams gain valuable time to implement the necessary updates without the pressure and fear of being hacked.

Administrative Decisions and Flexibility

Security administrators with FSP from Secfense have full control over the authentication process. They can choose a multi-factor authentication method and quickly run it in any application. In addition, it is up to them to decide which applications should be protected by the FSP option and which can benefit from a more lenient security policy. FSP can be turned on and off in the admin panel, giving you flexibility in managing security.


Secfense Full Site Protection is a step forward in protecting organizations from the rapidly changing landscape of cyber threats. It provides advanced protection against zero-day attacks and increases IT systems’ overall resilience against various cyber threats. In an era of increasing cyberattacks, FSP from Secfense is a critical tool in any organization concerned about the security of its data and resources.

We are faced with new challenges every day. We must always be one step ahead of the attackers and know what they are going to do before they do it. We are convinced that the User Access Security Broker will bring security to a new level, both for those working at the office and from home. For us, working with Secfense is an opportunity to exchange experience with developers who put great value on out-of-the-box thinking.

As part of the pre-implementation analysis, we verified that users utilize a wide range of client platforms: desktop computers, laptops, tablets, smartphones, and traditional mobile phones. Each of these devices differs in technological advancement, features, and level of security. Because of this, and also due to the recommendation of the Polish Financial Supervision Authority (UKNF), we decided to introduce additional protection in the form of multi-factor authentication mechanisms based on FIDO. As a result, users of our applications can log in safely, avoiding common cyber threats such as phishing, account takeover, and theft of their own and their clients’ data.

Before investing in Secfense, we had the opportunity to talk to its existing clients. Their reactions were unanimous: wow, it’s so easy to use. We were particularly impressed by the fact that implementing their solution does not require the involvement of IT developers. It gives Secfense a huge advantage over the competition, and at the same time opens the door to potential customers who so far were afraid of changes related to the implementation of multi-factor authentication solutions.

Even when the network and infrastructure are secured enough, social engineering and passwords can be used to gain control of the system by attackers. Multifactor authentication is the current trend. Secfense addresses this and allows you to build zero trust security and upgrade your current systems to passwordless applications within minutes, solving this problem right away,” said Eduard Kučera, Partner at Presto Ventures and cybersecurity expert – former Director in hugely successful Czech multinational cyber security firm Avast.

One of the biggest challenges the world is facing today is securing our identity online. That’s why we were so keen to have Secfense in our portfolio. They make it possible to introduce strong authentication in an automated way. Until now, organizations had to selectively protect applications because the deployment of new technology was very hard, or even impossible. With Secfense, the implementation of multi-factor authentication is no longer a problem, and all organizations can use the highest standards of authentication security.

Two-factor authentication is known to be one of the best ways to protect against phishing; however, its implementation has always been difficult. Secfense helped us solve that problem. With their security broker, we were able to introduce various 2FA methods on our web applications at once.
