Xiid Corp. announces a leap forward in tunneling technology with Xiid SealedTunnel 4.0. This major new product release extends SealedTunnel’s capabilities and reshapes what’s possible with cyber defense while fortifying Xiid customers against today’s most pressing cybersecurity threats. These include the surge in ransomware and the explosion of IoT devices, to dangerous misconfigurations across hybrid multicloud environments, new vulnerabilities arising with the growing adoption of AI, credential leaks and supply chain tampering, and the risk of zero-day attacks that keep every system administrator on edge.

“SealedTunnel 4.0 empowers enterprises with an exceptional level of performance and scalability via carrier-class features that provide for more resilient global operations,” said Xiid CTO Federico Simonetti, a security expert with experience in academia, forensic law enforcement and ethical hacking. “There is simply nothing like it on the market. SealedTunnel greatly improves connection and access speeds while maintaining persistent connections even in the ‘dirtiest’ and noisiest public internet environments.”

SealedTunnel 4.0’s powerful new capabilities include:

H2 streaming for unbeatable performance: The lossless and low-latency H2 streaming capabilities of SealedTunnel 4.0 establish connections 3 to 6x faster, delivering a far better alternative than traditional tunneling methods such as UDP streaming or WebSockets.
Anti-fingerprinting techniques for added privacy and control: Many organizations use VPNs to enhance their privacy and security, but VPNs are easy to fingerprint. That means adversaries can identify when you are using a VPN and shut it down to prevent you from communicating. SealedTunnel 4.0 makes it much harder for bad actors to do fingerprinting, which means adversaries cannot block your communications.
Fully synchronized connector nodes for failover without interruption: With SealedTunnel 4.0, interruptions from connector node outages are a thing of the past. Rather than marrying the endpoints on a connection to an individual connector node, 4.0 leverages a geographic cluster of smaller local clusters. That way, if a connector node goes down, another connector from the cluster can keep the connection going.
Automation for ease of installation and deployment: The new SealedTunnel introduces configuration templates, as well as a new “magic download links” feature that allows users to build special URLs to download individual installers that not only deploy the software but also pre-configure and activate it – all with zero user intervention. Magic download links are especially valuable when businesses need to install and preconfigure hundreds or thousands of tunnels on large collections of endpoints. It works like magic!
A 100% redesigned and streamlined UI for ease of use: SealedTunnel’s redesigned user interface makes every management task easier. Now everyone from a computer programmer to a CIO or CISO to a junior-level system administrator can use it.

SealedTunnel 4.0 still features the outbound-only, triple-layer, quantum-secure encryption to enable Xiid’s enterprise and government customers to increase security while lowering costs.

“VPNs, traditional tunnels and break-and-inspect approaches to cybersecurity are too slow, stop at zero trust and leave the door open – often creating as many problems as they solve,” added Simonetti. “SealedTunnel is the only true Zero Knowledge Networking offering and the only tunneling solution that gives systems administrators genuine peace of mind. Many of our Xiid customers are saving money by switching from traditional VPNs and tunnels to SealedTunnel because it is competitively priced, they no longer have to pay tens of millions worth of licenses each year, and its efficiencies empower system administrators to work smarter and do more. Now, with the new SealedTunnel 4.0 capabilities, we’re making SealedTunnel even more compelling.”
