Implementation of Citrix Remote Access Gateway ensures secure remote access to DTEK's corporate resources

DTEK needed to upgrade its outdated system to provide remote access for non-domain users, as Microsoft's UAG proxy server was about to expire. Moreover, the current solution lacked the ability to use SSL pre-authorization of clients due to the excessive load on the solution, and the solution itself was based on the outdated Windows Server 2008 R2 operating system.

This was especially important for DTEK when choosing a solution:

- The presence of the solution in the Gartner Magic Quadrant for ADC

- Availability of centralized identification and access control

- Provision of access based on Active Directory

- Vendor support for the solution with the ability to create cases 24/7

- Support for mobile access

- HTTP; HTTPS; FTP; SMTP; TCP; UDP protocol management for managing different types of traffic, etc.

After analyzing the solutions, the MODUS X team chose Citrix ADC for implementation in DTEK's infrastructure, which was implemented within 3 months.

Every day, up to 2000 employees of the company, as well as contractors and call centers working on non-corporate equipment, actively use the system, which demonstrates a high level of engagement and reliability of the solution. The solution has a high bandwidth that effectively supports a large number of simultaneous sessions without losing performance or efficiency. The new solution has demonstrated a high level of security when connecting from uncontrolled, non-domain equipment, providing examination of this equipment before connection, taking into account the binding of a unique user ID and his equipment in each specific session.

In general, Citrix ADC remote access solution provides a number of benefits for companies of different sizes and business application access needs, including

Flexibility of work: employees can work from any device, regardless of their domain, which allows them to maintain a high level of productivity even in unforeseen situations.

Security and access control: IT teams receive additional opportunities to protect corporate data and control access to it from any device: protection against DDoS attacks, integration with external multi-factor authentication systems (Microsoft Entra, Okta, Cisco VSA) to ensure that only authorized users have access.

Checking the availability of up-to-date antivirus systems and OS updates for compliance with information security requirements. If the requirements are not met, access to applications will not be provided, which provides an additional level of protection against potential threats and intruders. This allows you to maintain high security standards and ensure that all devices that interact with corporate systems are secure and up to date.

Business continuity: using standard corporate infrastructure to organize remote access allows you to maintain business continuity without the need to implement additional tools or devices, geo-redundancy and load balancing to ensure application fault tolerance and speed, etc.

System scaling: as the number of users grows, the system allows for efficient scaling, ensuring stable operation of the service even when a large number of users are simultaneously connected and the required Internet access speed is maintained.

Speed of connecting new users: thanks to integration with Microsoft Active Directory, the system allows you to connect new users by adding them to the appropriate access groups, which is a key advantage in conditions of dynamic growth or when you need to quickly expand your team.

Currently, the solution allows connecting to the company's corporate SharePoint portals, mail and terminal farms. In addition, DTEK actively uses the reverse proxy functionality within Citrix ADC, which allows users to connect to authorized resources without the need for re-authorization. This feature simplifies access to the necessary tools and data, optimizing workflows and increasing overall user productivity.
