Lastwall, a leading cybersecurity solutions provider of highly secure, identity-centric, and quantum resilient technologies, is debuting Quantum Shield, a first-of-its-kind quantum resilient product designed to help enterprises withstand the threat of “Q-Day”—the moment stolen data is decrypted once quantum computers are able to break current encryption standards. Quantum Shield aims to protect conventional network infrastructures with the latest cryptographic standards, ensuring intercepted data remains secure now and in the future.
Threats of “Steal-Now-Decrypt-Later,” or the penultimate Q-Day, maintain the capability to destabilize most modern encryptions. These campaigns target all sectors, from defense to critical infrastructure, posing a uniquely damaging threat landscape that leverages quantum computing.
The launch of Quantum Shield signifies a resistance to the aforementioned Q-Day, leveraging a National Institute of Standards and Technology (NIST) pre-approved algorithm that integrates Post-Quantum Cryptography (PQC) into the Transport Layer Security (TLS) layer of network traffic.
“Quantum Shield is a drop-in Transport Layer Security (TLS) terminator with load balancing capabilities. It replaces existing load balancers (using traditional encryption) with minimal configuration and no ‘rip and replace’ cost,” explained Karl Holmqvist, CEO of Lastwall. “Once deployed, Quantum Shield immediately increases security by integrating PQC into the TLS layer using a NIST pre-approved algorithm. This integration ensures that even when a quantum computer capable of breaking traditional encryption methods becomes a reality, the data protected by Quantum Shield remains secure.”
Quantum Shield—acting as a quantum-hardened network endpoint—enables more traditionally encrypted systems to have a secure channel for interfacing with the outside world, according to Holmqvist. Seamlessly replacing existing TLS terminators and load balancers, Quantum Shield rapidly brings organizations to a standard of quantum resilience, further meeting the highest and most rigorous standards of security, compliance, and efficiency.
Additionally, Quantum Shield empowers enterprises to use their existing monitoring tools, as the quantum-hardened endpoint sits on the edge of internal networks and doesn’t disrupt internal monitoring.
While “Quantum Shield is designed for…sectors requiring long-term secrecy such as government, defense, and critical infrastructure,” it also enables enterprises in other verticals to quickly and efficiently implement quantum resilient algorithms without time or resource drains, noted Holmqvist.
“Depending on an organization's maturity in dealing with quantum resilience, deployment of Quantum Shield can complement initial efforts to quickly establish a base level of resilience or can augment and scale existing work streams in the substantial effort required to ensure end to end full quantum readiness across the multiple dimensions of an organization's technology use,” Holmqvist continued.
As NIST approved algorithms continue to evolve to support quantum-resilient solutions, Quantum Shield is equipped with a crypto-agile structure that can be rapidly updated for the new NIST algorithms.
“We collectively need to move quickly to embrace quantum resilience and protect the internet,” explained Holmqvist. “In an age where infrastructure and defense teams are overloaded, Quantum Shield sets a new standard, equipping the industry with advanced features and flexibility to combat emerging quantum threats in minutes.”
