Yesterday, I had the privilege of attending the Microsoft Security Summit at Oslo Event Hub. A big thank you to the organizers and all the speakers for delivering such insightful and inspiring content! The event was packed with thought-provoking sessions on how security strategies must evolve in a world increasingly shaped by AI and cloud technologies. Here are some key takeaways that stood out to me:
1. Secure Future Initiative (SFI)
Microsoft’s Secure Future Initiative emphasizes building resilience against modern threats. The latest Microsoft Digital Defense Report 2025 highlights that attackers no longer “break in” — they log in. Identity compromise remains the primary attack vector.
2. Why You Should Read the Microsoft Digital Defense Report 2025
This year’s report is a must-read for anyone working in cybersecurity or digital transformation. It provides:
Global threat intelligence: Trends in ransomware, phishing, and identity-based attacks.
Actionable recommendations: The top 10 steps organizations should take to reduce risk.
AI-driven threat landscape: How generative AI is changing both attack and defense strategies.

3. Human-Operated Ransomware & Domain Impersonation
Patterns show that ransomware attacks are increasingly human-operated, leveraging stolen credentials rather than brute force. Domain impersonation in the age of AI adds another layer of complexity, making Zero Trust principles more critical than ever.
4. AI and Security – Opportunities and Risks
Bring Your Own AI: Employees are adopting private AI tools, creating challenges around data governance and compliance.
Shadow AI: Unapproved AI tools running in organizations pose significant risks. Visibility and control are essential.
Agent Registry: Maintaining a list of all AI agents and their permissions is becoming a best practice.
Human-in-the-Loop: For sensitive actions like financial transactions, human approval remains vital.
Microsoft’s Security Copilot and Defender XDR are examples of how AI can strengthen security posture while maintaining guardrails.
5. MCP – Model Context Protocol Server
The rise of AI agents and custom MCP servers introduces new security considerations. Hosting an MCP server requires:
Authentication & Logging: Strong identity controls and detailed audit trails.
Governance: Define what the MCP server can access and enforce guardrails.
Integration with Microsoft Sentinel: Use KQL-based tools for monitoring and anomaly detection.
MCP is not just a technical component—it’s a security control point for managing AI-driven workflows.
6. The Frontier Firm & Future of Work
The Work Trend Index 2025 and the concept of the Frontier Firm explore how organizations can accelerate value realization through cloud and AI modernization—balancing speed with control.
7. Practical Steps
Implement Zero Trust across identities, devices, and workloads.
Use Defender for Cloud Apps and Microsoft Sentinel for advanced threat detection.
Ensure robust logging (firewall, device, and agent activity).
Regularly review AD backups and security baselines.
Security in the AI era isn’t just about technology—it’s about culture, governance, and continuous adaptation. As AI becomes embedded in workflows, organizations must provide secure, approved alternatives to public AI tools while enforcing strong guardrails.
