AI cybersecurity (H2)

AI's proficiency at cybersecurity use cases has become a necessity for security teams striving to stay ahead of the scale and sophistication of today’s advanced threats. Yet it's estimated that more than 80% of AI projects fail.1 There's no shortage of security vendors promising a wide array of AI capabilities to help teams achieve more … but which AI tools will actually help your SOC teams succeed?

Let's explore how you can make measurable improvements to your team's ability to detect and respond to cyber threats faster and with more precision and context — using the right AI tools.

  • Improved patient outcomes
  • Reduced data retrieval time from months to hours
  • Enabled real‑time access to patient data

What is AI-driven threat detection and response? (H3)

AI-driven threat detection and response is the use of AI technologies, including machine learning models, large language models (LLMs), and natural language processing (NLP) to augment and expedite threat identification, investigation, and mitigation in real time.

AI-driven threat detection and response modernizes security operations by automating otherwise highly complex, manual, time-consuming tasks and surfacing real-time, actionable insights to improve organizations' security posture and cyber resilience.

Which cybersecurity tasks is AI best for? (H3)

It's important to establish where AI can make a game-changing impact and where it's best to trust human problem-solving.

When to use AI (H4)

AI is best at tasks that involve high-volume data processing, pattern recognition, and support for real-time decisions. Think:

  • Threat detection
  • Incident response
  • Alert triage and summarization
  • Copiloting for workflow recommendations
  • Data ingestion and normalization (particularly helpful for SIEM onboarding)
  • Language conversion for detection rules and queries

When to leave it to the pros (H4)

When strategic judgment, nuanced decision-making, or deep business context are required, the risks of automation can outweigh the benefits. AI is no match for experienced security professionals for things like:

  • Escalated case investigation
  • Crisis management
  • Security architecture design
  • Threat hunting (though AI can help threat hunters with data enrichment and query generation)
  • Forensic investigations
  • Policy development and governance
  • Cybersecurity training and building a resilient corporate culture

How can AI improve threat detection? (H2)

For security leaders, the mandate is clear: Detect threats faster, reduce false positives, and keep teams focused on what matters. Traditional detection approaches, rooted in static rules and signature-based alerts, can't keep up with today's dynamic landscape — especially considering adversaries themselves are using AI for their own efforts. In fact, phishing attacks have surged 1,200% since the rise of GenAI in late 2022.2

To defend against the surge in attacks, AI-driven threat detection brings powerful advantages to security operations. It identifies patterns across massive datasets, learns from behavioral baselines, and surfaces subtle or emerging cyber threats that traditional tools and processes often miss. More importantly, it reduces the operational drag of noise and alert fatigue — giving analysts time back and enabling the SOC to scale without burning out the team.

What are other ways AI can enhance detection?

Security alert summarization and distillation (H3)

The traditional burden of sifting through hundreds or thousands of alerts daily, many of which are low-priority or redundant, has long been a major pain point for security analysts. AI tools can now summarize alerts and highlight those with the highest impact or urgency. Benefits include:

  • Significant reduction in time spent on triage
  • Prioritization of high-confidence threats
  • Automatic correlation of related events to show full attack chains

The AI Advantage

AI can learn from historical alert outcomes to suppress noisy rules and boost high-fidelity signals. Reducing the number of alerts and prioritizing their importance elevates analyst productivity and effectiveness at responding to those that are the highest priority.

Anomaly detection (H3)

At a scale that human efforts alone can’t realistically match, AI analyzes millions of events in real time to establish baselines for normal activity and surface anomalous activity that deviates from this norm. This can include:

  • Detecting unusual login patterns (geo-velocity, time-of-day anomalies, suspicious user activity)
  • Building context from correlation of multiple low-severity alerts across devices
  • Spotting rare process executions or protocol usage
  • Uncovering abnormal data access patterns (e.g., mass downloads)
  • Identification of slow lateral movement or “low and slow” exfiltration

The AI advantage

AI connects the dots across noisy logs to surface early signs of complex attacks and catches novel or stealthy threats that traditional rules or signatures miss.

Generating detection rules and query assistance (H3)

LLMs help create, translate, and optimize detection logic — converting common language into actionable results. Common use cases include:

  • Converting MITRE ATT&CK® techniques into detection queries
  • Translating detection rules across platforms (e.g., Splunk → Elastic)
  • Writing programming language queries from natural language prompts

The AI advantage

Teams now spend less time hand-coding detection rules and more time tuning and responding to threats.

Enriching and correlating threat intelligence (H3)

AI tools ingest threat intel, automatically matching it against internal telemetry. This results in:

  • Matching across endpoints, logs, and cloud environments with real-time Indicators of Compromise (IoCs)
  • Linking new threat reports to previously undetected behaviors
  • Suggesting new detection rules based on emerging threat actor tactics, techniques, and protocols (TTPs)

The AI advantage

AI tools shorten the gap between threat intel ingestion and actionable detection.

Detecting advanced attacks (H3)

Detection tools that use AI help security analysts elevate beyond one-at-a-time alert triage by providing higher-quality alerting, thereby scaling the amount teams can resolve. AI-driven detection tools:

  • Identify behavioral anomalies across users, endpoints, and network activity
  • Correlate low-level signals to detect lateral movement or command-and-control activity
  • Use statistical and pattern analysis to spot previously unseen attack techniques

The AI advantage

Now that you’ve successfully detected threats with the help of AI, let’s explore how AI can help you quickly respond to them.

How can AI improve incident response? (H2)

It’s not enough to have strong detection capabilities. Teams also need to be able to respond quickly. Traditional incident response processes are manual, fragmented, and dependent on limited human capacity. The right AI tools help teams break that cycle.

By automating repetitive tasks, enriching alerts with actionable context, and guiding analysts through triage and remediation, AI transforms incident response into a faster, more scalable, and more consistent function. It empowers teams to move from reaction to resolution with clarity and confidence — without adding headcount or burning out staff.

From triage assistance to step-by-step workflow guidance, here’s how AI integrates into the key stages of incident response.

Accelerating triage

Fast response can make the difference between threat containment and escalation. AI-driven response processes identify patterns across alerts and connect them into larger incident narratives. For example, AI-driven processes can:

  • Group alerts that are part of the same attack chain (phishing → credential use → lateral movement)
  • Suppress duplicates or false positives using learned behavior patterns

The AI advantage

AI-driven processes reduce alert fatigue and enable analysts to focus on priority incidents rather than noisy one-offs.

Context enrichment

By instantly enriching alerts with contextual data, AI-driven response accelerates triage — connecting users, assets, and potential attack paths — without all the manual sleuthing. Analysts can now move confidently through response workflows in a fraction of the time. AI helps by:

  • Automatically enriching alerts with context (e.g., threat intel, geolocation, asset criticality)
  • Summarizing event timelines and root cause analysis in natural language
  • Highlighting affected users, systems, and paths of lateral movement

The AI advantage

AI elevates the skillset and understanding of every analyst while reducing time spent gathering basic context.

Automating playbooks

Unassisted by AI, incident response can be slow, error-prone, and inconsistent. AI-automated playbooks trigger the right actions based on alert context, threat severity, and historical outcomes. This ensures faster containment, reduces analyst workload, and drives more consistent response across the SOC.

For example, AI-driven response:

  • Kicks off automated response actions based on detection type (via SOAR or built-in automation actions)
  • Uses conditional logic to escalate or contain based on severity and context
  • Learns from past incidents to optimize playbook decisions

The AI advantage

AI allows for automatic and accurate quarantining of infected endpoints, disabling of compromised user accounts, and blocking of malicious IPs or domains.

Copilot guidance

Even experienced analysts can struggle with uncertainty during fast-moving incidents. AI-driven guidance acts as a real-time copilot, suggesting investigation steps, surfacing similar historical cases and data, and highlighting the next best steps to take at each phase of a response. It accomplishes this by:

  • Recommending context-aware actions based on the specific alert type, affected systems, and past resolution paths
  • Linking related incidents and threat intelligence to help analysts quickly understand scope, tactics, and potential impact
  • Providing natural language summaries for each suggestion, making decisions easier to validate and execute

The AI advantage

With AI-driven guidance, analysts can make accelerated, consistent, and accurate decisions during incident response, elevating analyst productivity and confidence.


Fresh-squeezed data (H3)

Of course, even with the best AI tools on the market, a team’s ability to detect and respond is only as good as the data they can analyze. Fortunately, AI again shows strong ability to help teams ingest, normalize, and analyze their data like never before.

In the next section, see how AI is helping teams onboard data and ease SIEM migration to maximize detection and response through improved visibility.
