FAQs

Does AI replace security analysts? No — it augments them. Tier 1 alerts are automated; humans handle escalations.

Is AI creating new attack surfaces? Yes — prompt injection and data poisoning are rising threats. OWASP LLM Top 10 addresses them.

How fast is AI incident response? SentinelOne and CrowdStrike respond in seconds vs. hours for manual SOCs.

What's the best AI tool for SMBs? Microsoft Defender for Business with Copilot — strong coverage at SMB price.

Are deepfakes a real threat? Yes — the 2024 $25M Hong Kong deepfake CFO fraud showed the risk is immediate.

How should I train staff? Phishing simulations (KnowBe4), deepfake awareness, and AI-specific social engineering tests.

Conclusion

Cybersecurity in 2026 is an AI vs AI battle. Defenders using CrowdStrike + Abnormal + Splunk AI stay ahead; those without fall behind within months.
