Cybersecurity 2025–2026: What’s Next After "Inside Cyber"
4 min read
When I published my book last Fall, Inside Cyber: How AI, 5G, IoT, and Quantum Computing Will Transform Privacy and Our Security, my goal was to provide a roadmap for understanding and preparing for the technological forces reshaping cybersecurity. The book examined how innovation intersects with risk and what leaders need to do to adapt.
As we step further into 2025 and 2026, many of the trends I highlighted in Inside Cyber are accelerating. In particular, artificial intelligence and quantum computing are moving from theoretical concerns to practical challenges—and they are reshaping the way we think about digital trust, resilience, and national security.
AI: A Double-Edged Cyber Weapon
Artificial intelligence has become a defining technology of this era.
For attackers: AI tools are being weaponized to automate phishing campaigns, generate deepfake videos, and develop adaptive malware that can evade traditional defenses. The scale and precision of these attacks are unprecedented.
Weaponized AI — Cybercriminals are leveraging generative AI to craft convincing deepfakes, voice clones, and hyper-personalized phishing attacks. As I discuss in the book, “Hackers now use generative AI to mimic voices and videos, creating deepfakes that can convincingly impersonate anyone".
For defenders: AI enables real-time anomaly detection, predictive modeling, and automated incident response. Security teams can shift from reactive to proactive strategies with the right AI-driven tools.
AI-Powered Defense — On the flip side, defenders are using AI-driven anomaly detection, behavioral analytics, and automated response to outpace threats in real time. Action: Build in AI ethics, transparency, and governance from the start—avoid reactive patches, embed responsible innovation.
The challenge isn’t AI itself—it’s how organizations adopt it. Without proper governance, transparency, and ethical controls, AI can quickly become a liability rather than a shield.
Quantum: Preparing for “Q-Day”
In Inside Cyber, I warned that quantum computing would eventually disrupt today’s encryption standards. That warning is becoming more urgent.
Q-Day Threat: RSA and ECC encryption, which protect much of our global digital infrastructure, are vulnerable to future quantum algorithms.
Data at Risk: Information stolen today can be stored and decrypted by quantum tools later. That means adversaries don’t need quantum now to cause long-term damage.
Post-Quantum Cryptography (PQC): Governments and enterprises are beginning to adopt NIST’s PQC standards, but migrations must start immediately. Preparing after Q-Day arrives will be too late. PQC adoption isn’t optional—it’s an imperative. Organizations must begin assessing cryptographic risk and planning migrations now to avoid being caught flat-footed.
Key Requirements for 2025–2026
Trends:
The expanding threat landscape powered by IoT, AI, and quantum.
The convergence of digital domains and its impact on privacy posture and risk.
Strategic frameworks that help envision both the hazard and opportunity in emerging tech convergence
To meet the challenges of the next two years, organizations must focus on:
Zero Trust Everywhere – Extending beyond IT into OT, supply chains, and critical infrastructure.
Responsible AI Adoption – Embedding governance, transparency, and bias mitigation into AI deployments.
Post-Quantum Readiness – Conducting cryptographic inventories and migration plans now.
Resilience as Strategy – Building cultures, processes, and technologies that enable rapid recovery after inevitable incidents.
Cyber Workforce Development – Closing the persistent skills gap with cross-disciplinary training, reskilling, and diversity initiatives.
Looking Ahead
Inside Cyber emphasized that cybersecurity is more than technology—it’s about insight, foresight, and collaboration. Those principles remain just as relevant in 2025 and 2026, even as the tools and threats evolve.
Inside Cyber aspired to give readers a practical lens on tech transformation. Now, those insights are becoming operational necessities. Boardrooms, national institutions, and practitioners must elevate cybersecurity as a strategic competitive and resilience.
Cybersecurity is no longer a back-office function. It is a strategic imperative that impacts trust, competitiveness, and national security. Organizations that prepare today—by embracing responsible AI, planning for quantum, and embedding resilience—will be the ones that thrive in the digital future.
