Compare Proton VPN vs. VMware ESXi vs. VirtualBox

Secure your organization from costly data breaches while meeting essential compliance requirements, such as ISO 27001, GDPR, and HIPAA. Our software-based VPN solution is easy to deploy alongside your existing systems, giving you a powerful and adaptable tool for securing your enterprise network. Our VPN Professional plan allows your team to connect securely to your local networks and cloud-based services. And with granular segmented control over who can connect to dedicated VPN servers and Gateways (logical groupings of dedicated servers), you can ensure your staff can access the resources they need (but only what they need). All of our business plans use robust industry-standard AES-256 or ChaCha20 encryption to ensure your data remains secure. You can further strengthen your organization's security with enforced two-factor authentication (2FA) and seamless login through single sign-on (SSO) with SCIM support for automated user provisioning. Our global high-performance (mainly 10 Gbps) server network is one of the largest in the world, and is part of the trusted Proton ecosystem — a suite of fully open source, end-to-end encrypted services built by the creators of Proton Mail and designed specifically to keep your business secure.

Explore a powerful bare-metal hypervisor that can be directly installed on your physical server. By providing immediate access to and management of the underlying hardware resources, VMware ESXi efficiently divides the server's capabilities to merge applications and reduce expenses. This hypervisor is recognized as the industry standard for effective architecture, exemplifying reliability, high performance, and excellent support. As IT teams face ongoing challenges to adapt to changing market demands and increased customer expectations, they also need to optimize their resources for more complex projects. Thankfully, ESXi aids in achieving a balance that promotes improved business results while also ensuring cost savings in IT operations. Its design not only enhances operational efficiency but also empowers organizations to innovate without compromising their budgets.
