Post-quantum security deadlines force leaders to protect existing infrastructure

Post-quantum security deadlines force leaders to protect existing infrastructure The post-quantum security transition is emerging as one of the most pressing challenges facing enterprise and government infrastructure, as “harvest now, decrypt later” attacks — in which adversaries steal encrypted data today to unlock once quantum computers mature — move from theory to active concern. Estimates for when quantum machines become a credible threat have steadily compressed from mid-century toward the end of this decade, and regulators are responding. In June, a U.S. executive order set new federal post-quantum deadlines for the most sensitive systems. Yet the underlying issue is not quantum-specific, according to José R. Rosas-Bustos (pictured), chief executive officer of EigenQ Inc. “The fact is that this is not a quantum problem. This is a crypto agility problem,” Rosas-Bustos said. “This is a problem that we have been facing as an industry for a long time. If we had already implemented countermeasures for crypto agility in the past, we would not be facing the issues that we’re facing today.” Rosas-Bustos spoke with Krista Case at Black Hat USA, during an exclusive broadcast on theCUBE, SiliconANGLE Media’s livestreaming studio. They discussed post-quantum security readiness, crypto agility and how leaders can protect existing infrastructure investments while preparing for a quantum future. (* Disclosure below.) Post-quantum security requires crypto agility Compute infrastructure is the layer that must be protected first, and enterprises can’t simply replace their entire server fleet to get there. EigenQ, an applied quantum technology company, has moved to embed quantum-resistant protection at the hardware level, including new capabilities that ready deployed Intel Xeon systems for CNSA 2.0-aligned migration. The company also launched an OEM server with Hewlett Packard Enterprise Co. and Intel Corp., though broad market options remain scarce, Rosas-Bustos noted. “We launched on June 17th, the first compute infrastructure server that has quantum-resistant technology integrated by the manufacturer along with HPE and Intel. But there is not a wide offering,” he said. “So then even if you want to try to do the low-hanging fruit, actually you don’t have so many options.” The convergence of AI and the quantum threat is compressing timelines that the industry once assumed stretched into the 2030s, pulling deadlines forward to 2027 for critical sectors. That urgency, Rosas-Bustos argued, exposes the weakness of treating each new cipher as a fix. “If you are recommending a solution that is only upgrading a cipher, you are just putting a Band-Aid on an underlying issue,” he said. “Upgrading a cipher is not enough. Implementing crypto agility, on the other hand, creates a skill that provides the organization a strength that is long-lasting.” Here’s the complete video interview, part of SiliconANGLE’s and theCUBE’s coverage of Black Hat USA 2026: (* Disclosure: EigenQ sponsored this segment of theCUBE.
