These capabilities allow AI to automate & elevate many cybersecurity functions:

• Reviewing vast amounts of network & system activity to identify potential threats.
• Parsing security alerts & system logs at machine speed to prioritise incidents. 
• Generating & distributing alerts on emerging indicators of compromise.
• Scanning software codebases to detect vulnerabilities & bugs.
• Translating threat intelligence reports into action plans. 
• Creating network traffic baselines to detect anomalies indicative of attacks.
• Automating responses like password resets, system shutdowns & connection blocking.

AI & ML technologies enable security teams to proactively hunt for threats, respond faster to attacks & make efficiencies in routine functions.

Key Benefits of AI in Cybersecurity

Implementing AI-enhanced solutions can provide organisations with substantial benefits:
