„Quantum Security“: How companies can protect data and systems

Quantum computing uses the laws of quantum mechanics to solve problems that are too complex for classical digital computers. The technology marks a paradigm shift in computing power and brings a new dynamic to the IT world. This has far-reaching consequences for the security of data and systems.

Our white paper „Quantum Security“ shows how organisations can classify technological developments at an early stage, prioritise risks and derive actionable measures to further develop their security architecture in an effective and future-proof manner. 

Forecasts predict that the global market for quantum computing will reach a volume of 50 billion US dollars by the end of this decade. Large technology companies are already offering commercial quantum computing services, and competition with new market entrants is accelerating the further development of the technology. However, these advances have a downside: as quantum computers become more widespread, the risks to cyber security also grow.

For businesses, this means that strategic decisions need to be made today, because quantum computing is no longer a distant vision of the future. Even though quantum computers are not yet widely available, the technology is developing rapidly, and businesses should begin preparing for quantum-secure measures just as quickly, especially where security and long-term data confidentiality are concerned. Companies that act early minimise risks and position themselves as pioneers in a new era of security. 

Quantum computers render many of today's widely used cryptographic tools ineffective. These tools currently protect everything from bank transactions and business data to documents, emails and sensitive communication channels. With quantum computing, these cryptographic methods lose their protective effect. The implications are enormous: authenticity, confidentiality and integrity are at risk. The threat affects not only individual systems, but the entire architecture of cybersecurity.

The transition to quantum-secure processes is complex and takes time. With the increasing prevalence of quantum computing, there is a growing risk that your own security architecture will no longer be able to meet the requirements of a new reality. Quantum security is therefore not just a technical adjustment, but a strategic necessity. Our white paper highlights the critical areas that are particularly threatened by quantum computing, outlines the key questions that form the starting point for planning a robust quantum security strategy, and identifies possible starting points for preparation.
