Quantum can wait: Why CISOs should focus on today’s preventable cyber risks
CISOs are increasingly focused on the long-term threat of quantum computing, but the immediate priority should be addressing today's preventable cyber risks. Most major breaches stem from poor cyber hygiene rather than advanced threats, highlighting the need for stronger foundational security practices. While quantum computing will eventually impact encryption, it is unlikely to pose a real threat until the 2030s.
- ▪Quantum computing is expected to break current encryption methods, but credible estimates suggest this won't happen until the early to mid-2030s.
- ▪Many recent cyber attacks have exploited gaps in basic cyber hygiene, such as weak MFA and poor EDR deployment.
- ▪CISOs risk overlooking fundamental security measures by focusing too heavily on future threats like quantum computing.
- ▪Organizations should prioritize improving existing security controls rather than over-investing in theoretical future risks.
- ▪Guidance from bodies like the NCSC has elevated quantum computing on strategic agendas, potentially diverting attention from current vulnerabilities.
