Quantum Threat Looms: Are We Ignoring Today's Breaches?

The cybersecurity industry faces a dilemma, with quantum computing capturing attention while current, basic vulnerabilities are exploited. CISOs are increasingly questioned about quantum readiness, a significant long-term concern estimated for the early to mid-2030s.

However, this futuristic threat can overshadow critical, ongoing security issues. Many cyberattacks over the past decade reveal gaps in fundamental cyber hygiene. Criminals exploit weak credentials, missing patches, and configuration failures, often finding social engineering more cost-effective than advanced decryption.

Organizations often possess an "illusion of security," with dashboards showing high coverage for tools like MFA and EDR, but lack clarity on actual implementation. Unmanaged devices, dormant accounts, and misconfigurations contribute to systemic exposure.

Security leaders should prioritize measurable prevention by ensuring MFA enforcement, EDR deployment, and timely patching. Eliminating blind spots through accurate asset inventories and validating control functionality is essential. Prevention performance also needs board-level attention.

While preparation for future risks like quantum is sensible, it should not detract from addressing current, exploitable vulnerabilities. Discovery and roadmap planning for cryptography can improve current security and ease future transitions. The next wave of breaches will likely stem from overlooked, preventable risks.
