Monitoring-as-a-Service: Continuous Tor Threat Intelligence Without Deployment

Not Every Organization Needs to Run Sensors

NodeSight's core technology — eBPF-based packet capture at Tor exit relays — requires deploying and operating sensor infrastructure. For large enterprises and government agencies with dedicated security teams, this is the optimal approach: full control, full visibility, air-gapped deployment.

But many organizations want the intelligence without the infrastructure. They want to know when their data appears in Tor exit traffic, without managing exit relay sensors.

This is what our Monitoring-as-a-Service (MaaS) model delivers.

How It Works

NodeSight operates a global network of sensors at Tor exit relays. These sensors continuously analyze exit traffic using our proprietary ensemble inference pipeline. When a sensor detects traffic matching a customer's configured alert criteria — domain names, credential patterns, data fingerprints, IP ranges — the customer receives a structured alert.

The Pipeline

Configuration — customers define their monitoring scope: domains, email patterns, data fingerprints, custom regex patterns

Continuous monitoring — our sensor network processes exit traffic in real time, matching flows against customer configurations

Alert generation — matches produce structured CEF events with full metadata: timestamp, exit relay, flow characteristics, confidence score

Delivery — alerts are delivered via API, webhook, SIEM integration, or analyst-curated digest

Data Privacy

A critical concern: does NodeSight see customer data? No. Our sensors extract flow metadata and statistical features — timing signatures, entropy measurements, packet size distributions. We do not capture or store payload content. The matching is performed against metadata patterns, not raw data.

• Up to 50 monitored domains
• Real-time alerting (< 60s delivery)
• SIEM integration (Splunk, Sentinel, QRadar)
• 4 hours/month dedicated analyst time
• 90-day alert history
• Custom matching rules

Enterprise — Custom pricing

• Unlimited domains
• Custom threat models and data fingerprints
• 24/7 SOC augmentation
• Air-gapped deployment option
• Unlimited history retention
• Dedicated account team
• SLA-backed detection latency

ROI Analysis

The economics are straightforward:

Without monitoring:

• Average breach cost: $4.45M (IBM 2023)
• Average detection time: 204 days
• Probability of Tor-based exfiltration: ~23% of breaches involve anonymization networks

With NodeSight MaaS (Professional tier):

• Annual cost: $102,000
• Detection time: < 1 minute
• Estimated breach cost reduction: 40-60% through early detection

For an organization facing even a single breach per 3 years, the ROI is approximately 12:1.

Integration

NodeSight MaaS integrates with existing security stacks:

All integrations support structured CEF (Common Event Format) events, which means alerts arrive as first-class security events in your SIEM — not as emails that require manual triage.
