Quantum computing looms, and your security is nowhere near ready
Quantum computing is getting closer, but most organizations are still unprepared for the security migration it will force.

The article says quantum computing is moving from theory into commercial reality, but security teams are lagging behind. Its main warning is that encryption upgrades, especially the shift to stronger standards, cannot wait.
Quantum computers are like super-powered problem solvers that may one day help with medicines, shipping, and other hard jobs. But the same power could also help them break some of the locks that protect digital information.
That is why the article says security teams need to start changing their locks now, not later. It is a bit like replacing the front door before a big storm instead of waiting until water is already coming in.
The piece also says this will take a long time because many companies use old systems that are hard to update. So the warning is simple: quantum computing may bring new tools, but it also brings a race to protect secrets before the old locks stop working.
Analysis
Quantum is arriving, but enterprise readiness is uneven
ZDNET frames quantum computing as an emerging reality rather than a distant idea. The article cites MIT research saying manufacturers are already offering more than 40 quantum processing units, and that quantum-as-a-service is widening access. Even so, the same report says current QPUs still do not meet the needs of large commercial workloads such as chemical simulation or cryptanalysis.
The bigger problem is security migration
The article’s central warning is that security teams cannot wait for quantum computers to mature before acting. Tim Steward of Fujitsu argues that encryption should no longer be assumed safe just because data is encrypted, and the piece says the best defense is moving from 128-bit to 256-bit encryption as soon as possible, citing NIST guidance. The article also quotes Palo Alto Networks executive Anand Oswal saying that by the end of the decade a cryptographically relevant quantum computer could break the encryption that supports much of the global economy.
Deadlines are already forming
Oswal says governments have started formal planning, including an EU quantum-safe communication network by 2030 and US NSA CNSA 2.0 mandates that already took effect last year. He also predicts RSA and ECC will be deprecated, then discouraged, and eventually disallowed for most applications by 2035. The article stresses that these migrations can take five to ten years in large enterprises, and may be impossible for some legacy systems, especially IoT and OT devices with embedded firmware.
Skills will be a bottleneck too
Beyond cryptography, the article says quantum talent is becoming harder to ignore. MIT data cited in the piece shows demand for quantum skills has nearly tripled since 2018, pointing to a growing need for specialists such as error-correction scientists and quantum algorithm developers.
Key points
- Quantum computing is moving closer to real enterprise use, but it is not yet ready for large-scale commercial workloads.
- The article warns that current encryption methods may not hold up once quantum systems mature.
- Experts quoted in the piece urge companies to move from 128-bit to 256-bit encryption now.
- Governments and standards bodies are already setting timelines for quantum-safe migration.
- Legacy systems, including IoT and OT devices, may be especially hard or impossible to upgrade.
