Data Visibility Challenges
Where security monitoring goes blind
The Visibility Problem
Modern networks have numerous blind spots where traditional monitoring tools cannot see. Attackers exploit these gaps to evade detection. Understanding where you can't see is just as important as knowing where you can.

Visibility Score Assessment
Based on common enterprise configurations, most organizations have significant visibility gaps:
Average Enterprise Network Visibility
This means ~55% of traffic may evade traditional monitoring
Addressing Visibility Gaps
Strategies and technologies to improve network visibility
TLS Inspection
Decrypt and inspect encrypted traffic at network boundaries.
- Deploy SSL/TLS inspection on firewalls and proxies
- Use certificate pinning exceptions for sensitive apps
- Implement enterprise CA for corporate devices
- Consider privacy implications and legal requirements
Cloud Visibility
Extend monitoring to cloud and SaaS environments.
- Cloud Access Security Brokers (CASB)
- Cloud-native logging (AWS CloudTrail, Azure Monitor)
- API integrations with SaaS providers
- Virtual TAPs for cloud workloads
Endpoint Visibility
Monitor at the endpoint where encryption terminates.
- Endpoint Detection and Response (EDR)
- Host-based logging and SIEM integration
- DNS query logging at endpoints
- Application behavior monitoring
Encrypted DNS Solutions
Maintain DNS visibility despite DoH/DoT adoption.
- Enterprise DoH/DoT resolvers
- Block external DoH providers
- DNS-over-HTTPS inspection
- Protective DNS services
