Multi-Cloud: How VPN Solutions Safeguard Hybrid IT Environments

In today’s business landscape, hybrid IT environments—where on-premises systems are connected with multiple cloud services—are increasingly common. Securing these multi-cloud structures can be a daunting challenge, especially for small and mid-sized businesses. Fortunately, specialized providers offer solutions that protect communication between employees, offices, and the cloud.

The Shift to Multi-Cloud: Moving Beyond Monolithic IT 

Initially, most companies relied on a single cloud provider, but now more and more businesses are combining multiple cloud solutions. They do this to avoid being dependent on a single provider (vendor lock-in). The resulting multi-cloud environments offer additional advantages. They are not only more flexible, but also generally better protected against issues. If one provider fails, the other services are still available.

Initially, most companies relied on a single cloud provider. Now, more organizations are adopting multi-cloud strategies to avoid vendor lock-in and increase flexibility. This approach not only reduces dependency on a single provider but also enhances resilience—if one service goes down, others remain available.

Hybrid environments have become the standard, blending a mix of local and cloud-based services. However, this shift brings new security challenges. In the past, IT resources were housed in secure, on-premises data centers, accessible only from company devices within the office. Security was simpler and more contained.

Today, the typical hybrid IT environment is far more open. While some core systems—like SAP or other ERPs—still run locally due to hardware or production requirements, many office and collaboration tools are now cloud-based. All these systems are interconnected, whether on-premises or online. Where a single VPN gateway once sufficed, modern environments require more sophisticated solutions to protect both legacy infrastructure and distributed cloud applications.

VPN Solutions: Connecting and Securing Distributed Systems 

Several types of VPN solutions are available for hybrid IT environments, often used in combination:

• Site-to-site VPN Connects two or more separate networks over the internet, creating a secure bridge between locations. Employees at each site can access shared resources without needing special software on their devices. VPN gateways manage these connections reliably.
• Client-to-site VPN Allows individual users to securely connect to the company network or cloud applications from remote locations. Employees use VPN software on their laptops, tablets, or smartphones to establish these connections—ideal for remote or traveling staff.
• Cloud VPNs, Operates directly in the cloud, linking on-premises networks, remote offices, and mobile users to cloud resources through encrypted tunnels. Cloud VPNs require no dedicated hardware, are highly scalable, and help reduce costs.

Navigating Complexity: Why Many Businesses Need Expert Support 

Securing hybrid environments is complex and often exceeds the capabilities of small and mid-sized IT teams. Common challenges include:

• How to secure both existing infrastructure and new cloud applications
• Managing user identities and access rights
• Deciding between multiple security products or a unified solution
• Avoiding compatibility issues
• Maintaining visibility and control
• Ensuring compliance and traceability

Providers like Nuremberg-based NCP engineering GmbH specialize in addressing these challenges. Their VPN solutions are designed for hybrid environments, securing not just remote access but all network connections to company servers and cloud services.

Key benefits include:

• No need for additional hardware or software investments
• Access to expert support for rapid deployment
• Predictable, transparent monthly costs with flexible licensing
• Seamless integration with existing IT infrastructure and directory services (LDAP, Active Directory, Microsoft Entra ID, IAM systems)
• Automated identity management for mobile users
• Built-in personal firewall for endpoint protection

Additional features:

• Two-factor authentication with one-time passwords (OTP)
• Integrated RADIUS server
• Policy enforcement
• Network Access Control (NAC)

With these solutions, businesses don’t need to navigate the complexities of Azure VPN Gateway, AWS VPNs, or Google Cloud VPNs on their own.

Conclusion

Hybrid multi-cloud environments are now the norm, offering greater flexibility and resilience. However, securing these environments is more challenging than ever. Modern VPN solutions ensure secure data flow between on-premises systems, cloud services, and mobile users.
