  1. Private AI. Shared resources. Clear boundaries.

    Does every department need its own AI infrastructure, or a secure share of yours?

  2. Your AI agent can act. Who defines success?

    Your AI agents need agreement on what “revenue” means before you give them permission to act.

  3. Systems offline. Is your business ready?

    Your business does not need to lose data to lose the ability to operate.

    Your Next Ransomware Attack Starts Here.

  6. Match AI compute to business value

    Your AI infrastructure decision belongs in the business case, before the purchase order.

  7. Agentic AI security

    Your next security risk could be an AI agent doing exactly what you authorized, with more access than the task requires.

  8. Wi-Fi 8 and 6G: plan ahead

    Wi-Fi 8 and 6G: prepare your roadmap. These technologies belong to the next several years, beyond today’s deployment decisions.

  9. Secure your third-party application access

    An attacker does not always need your password.

  10. AI agents need more than uptime

    Your AI agent can be available, fast and still doing the wrong thing.

  11. Build PQC into your network roadmap

    A few days ago, I shared several posts explaining post-quantum cryptography, why it matters, and how to start preparing.

  12. Find. Prioritize. Fix. Verify.

    An attacker may not need a password—or even reach your application’s login page.

  13. Great Wi-Fi starts beyond the access point

    Your next Wi-Fi upgrade may also be a switching upgrade.
