Frequently Asked Questions

Key Takeaways

Machine learning excels at processing massive amounts of network data to find patterns and anomalies that human analysts might miss.

AI encompasses broader capabilities, including reasoning and decision-making, while machine learning focuses specifically on learning from data patterns.

Generative AI (GenAI) is being used to speed up analyst workflows through natural language queries and automated summaries.

The most effective security strategies combine all three approaches rather than choosing just one.

AI vs Machine Learning: Key Differences

Artificial intelligence is any technology system that can do specific tasks that normally require human intelligence, such as reasoning, problem-solving, and decision-making. It’s a broad umbrella covering many different technologies.

Machine learning is a subset of AI. Instead of being explicitly programmed for every scenario, ML algorithms learn patterns from data. Feed an ML system thousands of examples of normal network traffic, and it learns to recognize what’s typical.

All machine learning is AI, but not all AI is machine learning.

Machine Learning vs AI: How They Work in Network Security

When security teams evaluate machine learning vs. AI capabilities in tools, they need to understand what each one actually does on a day-to-day basis.

Machine learning automates pattern recognition. It establishes baselines for what normal network behavior looks like — typical login times, usual data transfer volumes, standard traffic patterns. Once those baselines exist, ML monitors continuously for anomalies. If a user who normally logs in from New York suddenly authenticates from overseas, ML flags it. If traffic spikes unexpectedly on an internal server, ML catches it. The system classifies threats based on characteristics it recognizes from past data, handling millions of packets without needing analysts to review each one.

AI systems take what ML detects and add another layer of intelligence. Here’s where the practical difference shows up for SecOps and NetOps teams: ML might flag 10 suspicious login attempts, three unusual file transfers, and five odd network connections in a single hour. That’s 18 alerts for an analyst to review. AI looks at all 18 events, recognizes that they’re related, understands they represent stages of a lateral movement attack, and consolidates them into one high-priority incident with context about what’s actually happening.

The operational benefit is significant. Instead of chasing 18 separate alerts that may or may not be connected, your team gets one clear picture: “Compromised account detected, the attacker is moving laterally, and these are the affected systems.” AI makes adaptive decisions about which alerts deserve immediate attention and which can wait, reducing the noise that burns out security teams.

Generative AI vs Machine Learning: What’s New and What’s Different

Traditional machine learning focuses on classification and prediction. It analyzes network traffic to determine if it’s malicious or forecasts future patterns based on historical data. GenAI works differently. Instead of just analyzing existing data, it creates new content.

For security teams, this means GenAI can summarize thousands of alerts into coherent incident reports, generate custom queries for threat hunting, or explain complex attack patterns in plain language. The difference between machine learning vs. generative AI matters for security operations because of speed and efficiency. SOC analysts can ask questions in natural language and get immediate, contextual answers instead of manually reviewing alerts and writing queries.

The flip side is that GenAI also helps attackers. The same capabilities create convincing phishing emails, generate sophisticated malware code, and produce deepfake audio or video for social engineering. These are all new risks that weren’t part of the threat landscape even a few years ago.

Where AI, ML, and GenAI Fit Into Modern Network Security Architectures

Modern network security isn’t about choosing between these technologies — it’s about using each where it works best. Machine learning powers the foundational detection engines. It analyzes traffic flows, builds behavior models for users and devices, provides insights into encrypted traffic without decryption, and detects zero-day threats.

AI operates at a higher level by enabling automation that extends beyond individual detections. While machine learning identifies patterns and anomalies in large volumes of data, AI helps organize, enrich, and deliver network telemetry so security tools can interpret activity in context across complex environments. This is where AI and machine learning work together most effectively: machine learning provides scalable signal, and AI ensures that signal is prepared and presented in ways that support faster, more accurate analysis by downstream platforms.

Generative AI serves a different purpose — it accelerates human analysis rather than replacing detection systems. Security teams use it for natural-language threat hunting, automated generation of incident reports, and getting contextual explanations of why certain events matter. It’s a force multiplier for the people already on your team.

The Benefits of Machine Learning for Network Security

Machine learning has become essential for network defense because of how it handles data at scale. The benefits of ML include:

Processes massive volumes efficiently: ML algorithms can analyze huge amounts of network metadata and spot subtle anomalies.

Learns continuously: The more network traffic an ML system analyzes, the better it gets at distinguishing normal from suspicious. This makes it ideal for gaining encrypted traffic visibility without requiring decryption, which preserves privacy and performance.

Reduces noise: By learning baseline behavior for specific users, devices, and workloads, ML systems get better at filtering out false positives. This means analysts spend less time chasing alerts that turn out to be nothing.

The Benefits of AI for Network Defense

AI capabilities extend beyond what machine learning alone can provide. The benefits include:

Automates complex decisions: AI systems can make intelligent decisions by correlating data across multiple security and network telemetry streams. This provides a more complete picture of what’s actually happening across your infrastructure.

Prioritizes intelligently: Not all alerts deserve the same attention. AI can decide which ones are most critical based on context, reducing analyst fatigue and improving overall SOC efficiency.

Speeds response: When incidents occur, AI provides context-aware recommendations based on similar past scenarios. Some systems can even simulate different response options to help teams choose the best approach.

Generative AI’s Emerging Role in Network Security

Agentic AI and other generative approaches are starting to change how security teams work by:

Simplifying complex data: GenAI can take thousands of alerts, log entries, PCAPs, and ML-driven detections and summarize them into clear, analyst-ready insights. This dramatically reduces the time needed to understand what’s happening.

Enabling natural conversation: Instead of writing complex queries or digging through logs manually, analysts can ask questions in plain language. “Show me all unusual authentication attempts from this subnet in the past week” becomes a simple conversation.

Improving training and knowledge transfer: New analysts can learn faster when GenAI provides dynamic explanations of threats, attack techniques, and network behavior patterns. This helps teams scale their capabilities without requiring years of experience.

How Gigamon Uses AI, Machine Learning, and Generative AI

Gigamon uses AI, machine learning, and generative AI to improve visibility and security across hybrid cloud network environments, helping organizations see and understand activity that would otherwise remain hidden.

Rather than replacing security or observability platforms, Gigamon AI strengthens deep observability by delivering network-derived telemetry and application metadata that those tools depend on for effective analysis.

Machine learning is applied to network traffic and metadata to identify patterns and anomalies, including activity in encrypted, lateral (East-West), and ingress-egress communications. This improves network visibility without requiring decryption, enabling organizations to reduce blind spots while maintaining and optimizing performance and security posture.

The Gigamon Deep Observability Pipeline uses AI-powered intelligence to enrich network telemetry with application-level context and efficiently deliver it to security, observability, and cloud platforms. By improving the quality and consistency of the data those tools receive, Gigamon supports more accurate detection, correlation, and investigation performed downstream, while maintaining a clear separation from security analytics and response functions.

Generative AI capabilities extend this foundation by helping teams interact with and understand network telemetry more efficiently. AI Traffic Intelligence provides visibility into GenAI and LLM application usage across hybrid cloud environments, supporting governance, policy enforcement, and spend management. Embedded assistants, including GigaVUE-FM Copilot, use generative AI to simplify configuration, validation, and troubleshooting workflows, reducing operational overhead.

Together, these capabilities supports our AI vision: using intelligent automation and trusted network-derived data to reduce complexity, improve operational efficiency, and strengthen security outcomes. This visibility is foundational to Zero Trust architecture implementations, where continuous verification depends on understanding all traffic, including encrypted and lateral communications.

Organizations can see how Gigamon AI delivers this level of network visibility in action through a live demo, which shows how the deep observability pipeline integrates with existing tools in real-world scenarios.

AI vs Machine Learning: Which Should You Choose?

AI vs. machine learning isn’t really a choice between one or the other. Each technology serves different purposes, and the best approach uses all three strategically.

Machine learning is your foundation for consistent, scalable detection across high-volume traffic environments. It works around the clock and gets better over time as it processes more data.

AI is best when you need automated decision-making and want to reduce cognitive load on analysts. If your team is drowning in alerts or struggling to connect dots across multiple security tools, AI handles correlation and prioritization.

Generative AI enhances human understanding and accelerates workflows. It’s not meant to replace ML detection engines or AI correlation systems — it helps your team work faster by providing clear explanations and enabling natural-language interaction with security data. The Gen AI vs. machine learning debate misses the point: you need both working together.
