Detection techniques, visibility deep-dives, and security engineering from the InterroSec team.
Why Prophet Beats SMA for Network Anomaly Detection
Simple moving averages miss daily patterns. Here's why Facebook Prophet is better for detecting anomalies in network flow data.
PCI DSS Network Segmentation: What Auditors Actually Want
PCI DSS segmentation requirements are often misunderstood. Here's what auditors actually look for — and how to demonstrate it.
Understanding Network Traffic Baselines: Beyond Simple Averages
A meaningful network baseline captures rhythm, trend, and seasonality — not just the average of recent samples.
Hybrid Cloud Network Monitoring: On-Prem Meets Azure
When your workloads span on-premises infrastructure and Azure, network monitoring requires a unified approach to both environments.
When the Spike Doesn't Come: Detecting Absence Anomalies
Missing traffic can be as suspicious as unexpected traffic. Here's how to detect anomalies in what isn't happening on your network.
Microsegmentation Planning Without the Guesswork
Microsegmentation projects fail when they're designed on assumptions instead of observed communication data. Flow data changes that.
Solving Alert Fatigue with Auto-Resolving Anomalies
Persistent false-positive alerts train analysts to ignore them. Auto-resolution closes the loop and keeps signal-to-noise ratios high.
Auto-Discovering Cloud Topology from Flow Data
Cloud environments change faster than documentation can keep up. Flow-driven topology discovery shows you what's actually there.
Predictive vs Reactive NDR: Why Forecasting Matters
Reactive NDR catches threats after the fact. Predictive NDR changes the time equation — and that changes outcomes.
Zero Trust Starts with Visibility
Zero trust architecture requires knowing what's on your network and what it's doing. That knowledge comes from visibility, not policy.
Agentless vs Agent-Based: The Flow Advantage
Deploying agents on every endpoint isn't the only path to network visibility. Here's why flow-based monitoring is often the better choice.
Using Flow Data for HIPAA Network Compliance
HIPAA's network security requirements are less prescriptive than PCI DSS, but they demand the same underlying capability: knowing where PHI travels.
NetFlow, IPFIX, and sFlow: A Practical Guide
Three flow protocols dominate enterprise network telemetry. Here's what each one does, when to use it, and how to configure it.
From Flat Network to Segmented: A Practical Roadmap
Moving from a flat network to meaningful segmentation doesn't require a forklift upgrade. Here's the practical path.
Mapping Application Dependencies in Hybrid Cloud
Application dependency maps built from flow data show the actual communication graph — not what documentation says it should be.
Why You Need Policy Visualization Before Enforcement
Enforcing a segmentation policy without visualizing it first is how you break production at 2 AM. Here's a better approach.
East-West Traffic: The Blind Spot in Your Network
Most security tools focus on what enters and leaves the network. The lateral movement that leads to breaches happens inside it.
Making Sense of Azure NSG Flow Logs
NSG Flow Logs are Azure's primary network telemetry source, but they require careful setup and interpretation to be useful.
Flow-Based Network Visibility: The Complete Guide
Everything you need to know about flow-based network monitoring: how it works, what it covers, and how to deploy it effectively.
Audit-Ready Network Documentation in Minutes, Not Months
Scrambling to produce network documentation at audit time is avoidable. Here's how continuous flow monitoring changes the preparation equation.
