FAQs
What is the best AI tool for cybersecurity teams?
The right starting point depends on the control boundary. Perplexity helps with public-source research, NotebookLM with approved document sets, and Glean with governed enterprise knowledge.
Can security teams paste logs into public AI tools?
Not without approval. Logs can expose credentials, personal data, infrastructure, vulnerabilities, and customer information. Use governed systems and minimize data before analysis.
Can AI make autonomous security decisions?
High-impact containment and access decisions need validated rules, testing, audit trails, and accountable human oversight. Treat general assistants as support tools, not security authorities.
