IntroductionIn the previous article of our series, we discussed how to reduce latency across multi-cloud deployments. If you missed it, you can catch up here. Today, we’re going to discuss a crucial topic: finding the top alternative to Citrix Netscaler. As you all know, Citrix has recently undergone significant changes in management and strategy, focusing on simplifying its product offerings. This shift has brought numerous concerns, including increased support overhead and a lack of support for medium and small customers. Additionally, changes in the licensing model have introduced extra costs for contract renewals, adding to the overall financial burden on organizations.In this context, it’s essential to explore robust alternatives that can offer reliable performance, security, and cost efficiency. One such alternative is Thinfinity Workspace. This article will delve into why Thinfinity Workspace stands out as the top alternative to Citrix Netscaler.Let’s get into the meat of this real quick. Imagine a bustling corporate environment where the IT infrastructure must support hundreds of employees accessing critical applications simultaneously. The performance and reliability of these applications can make or break productivity. This is where Thinfinity® Workspace steps in, offering a robust and flexible solution that addresses the unique challenges faced by large organizations.

This can be changed by creating a local Load Balancing Virtual Server on the same appliance and sending authentication traffic through the Load Balancing VIP.Several of the Load Balancing monitors run as Perl scripts, which are sourced from the NSIPs, not SNIP. But actual load balancing traffic uses SNIP as the source IP.DNS Name Servers use ping for monitoring. This can be disabled by creating a local Load Balancing Virtual Server on the same appliance and sending DNS traffic through the load balancer.In a ADC with a dedicated management network and default route on a different data network, configure Policy Based Routes (PBRs) to send NSIP-sourced traffic through a router on the NSIP subnet.Logstream defaults to SNIP as source but can be changed to NSIP.

2025-03-25Author: Guus Beckers Back in 2022 Fox-IT decided to open source its proprietary incident response tooling known as Dissect. Since then it has been adopted by many different companies in their regular workflow. For those of you who are not yet familiar with Dissect, it is an incident response framework built with incident response engagements of any … Continue reading Decrypting Full Disk Encryption with Dissect → Authors: Boudewijn Meijer && Rick Veldhoven Introduction As defensive security products improve, attackers must refine their craft. Gone are the days of executing malicious binaries from disk, especially ones well known to antivirus and Endpoint Detection and Reponse (EDR) vendors. Now, attackers focus on in-memory payload execution for both native and managed applications to evade … Continue reading Red Teaming in the age of EDR: Evasion of Endpoint Detection Through Malware Virtualisation → Authored by Willem Zeeman and Yun Zheng Hu This blog is part of a series written by various Dutch cyber security firms that have collaborated on the Cactus ransomware group, which exploits Qlik Sense servers for initial access. To view all of them please check the central blog by Dutch special interest group Cyberveilig Nederland … Continue reading Sifting through the spines: identifying (potential) Cactus ransomware victims → Blog updated on 3 March 2023 to (i) remove a table containing data created on 09-01-23, more than one month earlier than publication of the original blog on 22-02-23 entitled ‘Backdoored ConnectWise R1Soft Server Backup Manager by Autonomous System Organization (Top 20 as of 2023-01-09)’; (ii) update a table containing data created on 09-01-23 entitled … Continue reading From Backup to Backdoor: Exploitation of CVE-2022-36537 in R1Soft Server Backup Manager → Authored by Yun Zheng Hu Recently, two critical vulnerabilities were reported in Citrix ADC and Citrix Gateway; where one of them
