Encrypted Web Traffic Visibility Gap Threatens SOC 2 Compliance
What Happened — As > 95 % of web traffic is now encrypted, many organizations still bypass SSL/TLS inspection to avoid performance penalties, creating blind spots where malware‑free, credential‑based attacks can operate undetected.
Why It Matters for Compliance & Audit Readiness
- SOC 2’s CC6.1 – System Monitoring requires continuous visibility into network traffic; unchecked encrypted channels constitute a control deficiency.
- Evidence of encrypted‑traffic inspection (or a documented risk‑acceptance) is needed to satisfy audit queries on CC6.2 – Incident Detection.
- Verisq’s Control Mapping capability can automatically map decryption‑inspection controls to SOC 2 criteria and collect continuous evidence for auditors.
Who Is Affected – Enterprises across finance, healthcare, SaaS, and cloud‑infrastructure that rely on web‑based applications and have adopted TLS 1.3.
Recommended Actions –
- Conduct a gap analysis of current SSL/TLS inspection coverage against SOC 2 CC6 requirements.
- Deploy a high‑performance decryption proxy (e.g., Symantec SSL Visibility) or a cloud‑native inspection service that logs decrypted traffic for audit.
- Document the risk‑acceptance decision if full inspection is not feasible, and capture supporting evidence in your compliance repository.
Technical Notes – The challenge stems from TLS 1.3’s encrypted handshake and forward secrecy, which prevent passive sniffing; only active, high‑throughput proxying can provide visibility without breaking applications. Source: Broadcom Symantec Blog
