Legacy VPN Replacement

75% of enterprises today are in some form of hybrid cloud deployment. Providing a seamless remote access solution that traverses this complex environment is a huge IT and security challenge.

The Problem

As enterprises progress on their digital transformation journey, they must enable secure remote access across their on-premises and cloud deployments. Network-centric solutions like traditional VPNs (Virtual Private Networks) are not designed to meet modern organizations’ scale, performance, and usability needs, especially with complex hybrid cloud environments. 

Legacy VPNs create a huge security liability as they offer overly-broad access to sensitive corporate networks and permit the kind of lateral movement that adversaries use for cyber attacks like malware, ransomware, and other illegal activity.

Securely providing true “work from anywhere” access to resources for an increasingly diverse workforce (employees, contractors, partners, etc.) from a multitude of devices has exceeded the capabilities of traditional VPNs.

And while VPN vendors have begun to roll-out “next generation” technology as a stop-gap, it is becoming increasingly apparent that organizations are moving away from these legacy VPNs toward strategies and frameworks based on zero trust security.

Management Complexity

  • No centralized way to secure IaaS, on-premises, and SaaS applications especially if applications can move across clouds.
  • Complex network-level policies to segment access, which have to be constantly updated to match dynamic user and application environments.

Massive Security Gap

  • Legacy VPN solutions grant full access to network resources, allowing malicious actors with VPN access to move laterally across the corporate ecosystem.
  • One-time authentication approaches fail to provide real-time detection or enforcement of detected abnormal activity.

Poor Performance & Scale

  • Due to deployment complexity, users experience performance delays and are often unable to access applications due to VPN connectivity issues.
  • VPNs can be very expensive to acquire, maintain, and upgrade.

Improved Security Posture

  • Own your data plane and provide differentiated access based on user, device, and other relevant attributes
  • Integrate with your existing PKI infrastructure / CAs to completely control the confidentiality and privacy of your data

Massive Management Simplicity

  • Homogeneous experience whether servers are deployed in IaaS or on-premises
  • Simplified experience whether IaaS, on-premises, or SaaS applications using our as-a-service Banyan offering

Seamless & Fast User Experience

  • Direct access to servers deployed on private clouds or Infrastructure as a Service (IaaS)
  • Supports general TCP protocols like MySQL

The Banyan Approach

As enterprises increasingly move to hybrid and multi-cloud environments, only Banyan offers a single platform to address the security risks and challenges of secure remote access for this ecosystem. The platform extends across on-premises to public cloud ecosystems enabling true management simplicity while offering the highest level of security posture.

The figure above shows in Steps 1-4 that access control checks are performed out of band to create a quantified trust score-based access paradigm matching with predefined least privilege access policies.

Step 3 is an example of an integration with tools like SSO and MDM to ensure that existing tools can be leveraged to generate a trust score.

Step 5 shows that access is granted, and the data path is direct to the application across clouds seamlessly.


Key Features for VPN Replacement

  • Integrate with your cloud infrastructure in AWS, Azure, GCP, or VMware and leverage their auto-scaling load balancers and DDoS protection systems
  • Write human-readable policies for differentiated access leveraging easy-to-use templates. Underneath the hood, a hybrid RBAC/ABAC system allows you to write highly custom policies, if needed
  • Passwordless access to application/servers
