Cybersecurity is being transformed by artificial intelligence (AI), which also provides a great benefit in spotting and reducing cyber vulnerabilities. Conventional security solutions usually fail to change as cyberattacks become more complicated. Using machine learning to examine large volumes, identify patterns, and find anomalies suggestive of possible hazards, artificial intelligence-driven threat detection seeks out Unlike conventional systems based on set rules, artificial intelligence can grow and improve on its own over time, hence it is very successful against changing cyberthreats. The main contribution of AI in cybersecurity is investigated in this article along with its ability to reduce human error, automate response systems & enhance threat detection. We will review network data, look at how ML algorithms predict possible breaches before they materialize & find the malware signatures. Furthermore, artificial intelligence-driven security solutions might improve incident response, therefore helping companies to reduce risks more quickly and precisely. Even if artificial intelligence clearly has advantages, problems such algorithmic bias, false positives, and the requirement of continuous monitoring still exist. We will also discuss ethical issues and the importance of reaching balance between human supervision and automation. AI-driven threat detection is becoming a transforming answer as cyber dangers develop, improving security measures in many different fields. Using creative algorithms and real-time data analysis can help companies aggressively reduce cyber risks and outrun attackers.
