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.

InstaSafe is redefining the challenge of secure access to modern networks by leveraging Zero Trust principles with its security solutions, that ensure seamless access to cloud applications, SAP applications, on-premise data, IoT devices, and multiple other neoteric use cases. InstaSafe discards traditional VPN based conceptions of a network perimeter, instead moving the perimeter to the individual users and the devices they access. The Zero Trust approach followed by InstaSafe mandates a “never trust, always verify' approach to privileged access, without focusing on network locality. InstaSafe ZTAA relies on continuously assessing the trust and risk associated with every user, and the context of their access request, and simultaneously employs a system of comprehensive authentication before grnating least privilege access. By only making authorised applications accessible to the user, and not exposing the network to these users, ZTAA serves to negate the exploitable attacks surface

Shieldoo is a next-gen private network for remote connection from anywhere built with a well-known open-source tool called Nebula. The Shieldoo secure network is a collection of nodes, a lighthouse, and an admin center. The user device is a node, the server is a node, the cloud stack is a node, and the LAN access box is a node. Two nodes discover each other through a lighthouse and then connect peer-to-peer. With Shieldoo, you can build a complex security infrastructure which is easy to use. A tailored wizard will guide you through the initial setup, and the usual administration is handled in the admin center. You pay only for users and servers seen in the network that month, and you always get the complete feature set: unlimited admin accounts, SSO, MFA, domain by your choice etc.

With Fudo, users can get access to Unix/Windows servers, applications, and devices quickly and easily. Users will not have to change their habits and can continue to use native clients like Unix Terminals, RDCMan, or Putty. They can also connect through the Fudo Web Client which only needs a web browser for access. Using the JIT feature, you can create access workflows that adhere to the zero-trust approach. Through the request management section, you can easily define and schedule when a specific resource is available to a certain user and control it accordingly. Fudo allows you to permanently monitor and record all the ongoing sessions for 10+ protocols, including SSH, RDP, VNC, and HTTPS. You can watch the session live or use the footage for post-mortem analysis. Both the server and end-user computers do not require any agents. Furthermore, Fudo offers the ability to join the session, sharing, pausing, and terminate, as well as great tools like OCR and tagging.

Remote workforce, BYOD assets, and third-party access have created a new security dilemma for organizations. Relying solely upon a VPN as security for remote workers and third-party access is insufficient to protect the network. While VPNs provide a degree of protection through encrypting inbound traffic, their security failure comes through providing full network access to users with no privileged access demarcation. RevBits ZTN encrypts, authenticates, and securely connects external users, over SSL/TSL, to internal network assets and applications to which they have specific access without granting full network access. Moving the network perimeter to the endpoint RevBits Zero Trust Network (ZTN) helps isolate and protect your internal assets. As the network perimeter moves to where the user is, RevBits Zero Trust Network (ZTN) helps isolate and protect internal network assets without the necessity of implementing complicated network segmentation.
