Cloudbrink
Cloudbrink
If you’ve ever dealt with slow VPNs, or clunky ZTNA agents that degrade app performance, you’re not alone. Many IT teams are stuck balancing security with usability—and often end up sacrificing both. Here is a different approach. The high-performance ZTNA service that is part of a personal SASE solution from Cloudbrink can upgrade or replace traditional VPNs while fixing the performance and complexity that come from other vendors in the ZTNA and SASE space. Built as a software-only service, Cloudbrink delivers sub-20ms latency and 1Gbps+ speeds per user using dynamically deployed FAST edges and a proprietary protocol that recovers packet loss before it impacts the app. Security isn’t bolted on—it’s built in. With mutual TLS 1.3, short-lived certs, and no exposed IPs, Cloudbrink provides real zero trust without making users suffer through poor connections or overloaded POPs. If you’ve been burned by “next-gen” solutions that still feel like 2008, it might be time for something new. -

Twingate
Twingate
The way we work has changed. People now work from anywhere, not just from an office. Applications are based in the cloud, not just on-premise. And the company network perimeter is now spread across the internet. Using a traditional, network-centric VPN for remote access is not only outdated and difficult to maintain, but exposes businesses to security breaches. VPN infrastructure is costly and time-consuming to procure, deploy, and maintain. Inability to secure access at the app level means hacks can expose whole networks. Twingate enables organizations to rapidly implement a modern Zero Trust network that is more secure and maintainable than VPNs. Delivered as a cloud-based service, Twingate empowers IT teams to easily configure a software-defined perimeter without changing infrastructure, and centrally manage user access to internal apps, whether they are on-prem or in the cloud.Starting Price: $10 per user per month -

DxOdyssey
DH2i
DxOdyssey is lightweight software built on patented technology that enables you to create highly available application-level micro-tunnels across any mix of locations and platforms. And it does so more easily, more securely, and more discreetly than any other solution on the market. Using DxOdyssey puts you on a path to zero trust security and helps networking and security admins secure multi-site & multi-cloud operations. The network perimeter has evolved. And DxOdyssey’s unVPN technology is designed with this in mind. Old VPN and direct link approaches are cumbersome to maintain and open up the entire network to lateral movement. DxOdyssey takes a more secure approach, giving users app-level access rather than network-level access, reducing attack surface. And it does all of this with the most secure and performant approach to create a Software Defined Perimeter (SDP) to grant connectivity to distributed apps and clients running across multiple sites, clouds, and domains. -
