Compliance Guide: GDPR, HIPAA, SOC 2 for Encrypted Communication
Navigate regulatory requirements for secure messaging with comprehensive coverage of GDPR, HIPAA, SOC 2, CCPA and other compliance frameworks.
Why Compliance Matters
Non-compliance with data protection regulations carries devastating consequences:
- GDPR fines: Up to €20 million or 4% of global annual revenue (whichever is higher)
- HIPAA penalties: $50,000 per violation, up to $1.5 million per year
- CCPA violations: $7,500 per intentional violation
- Loss of certifications: SOC 2, ISO 27001, and customer trust
- Reputation damage: 60% of customers abandon companies after breaches
Secure encrypted communication is your first line of defense against compliance violations.
GDPR (General Data Protection Regulation)
What is GDPR?
EU regulation protecting personal data of EU citizens. Applies to ANY organization processing EU citizen data, regardless of location. Effective since May 25, 2018.

GDPR Requirements for Secure Messaging
1. Data Protection by Design & Default (Article 25)
Implement technical and organizational measures to ensure high level of security:
- Pseudonymization and encryption of personal data
- Ability to ensure confidentiality, integrity, availability
- Ability to restore access to personal data after incidents
- Regular testing and assessment of security measures

- Any other unique identifying number or characteristic
Requirement: PHI can only be used/disclosed for treatment, payment, healthcare operations—or with explicit patient authorization.
2. Security Rule - Technical Safeguards
Requires "addressable" and "required" security measures:
Required Specifications:
- Access Control: Unique user IDs, emergency access, automatic logoff, encryption
- Audit Controls: Record and examine access to ePHI
- Integrity Controls: Protect ePHI from improper alteration/destruction
- Transmission Security: Protect ePHI in transit (encryption required)
Addressable Specifications:
- Encryption/Decryption: Implement mechanism to encrypt/decrypt ePHI (strongly recommended)
HexBurn Compliance: ✓ AES-256 encryption exceeds HIPAA standards, ✓ Zero data retention, ✓ Automatic access controls
3. Breach Notification Rule
Notify affected individuals, HHS, and potentially media:
- Individual notification: Within 60 days of discovery
- HHS notification: Within 60 days (or annually for small breaches)
- Media notification: If breach affects 500+ individuals in a state/jurisdiction
- Business associate notification: To covered entity without unreasonable delay
Safe Harbor: Encrypted data is NOT considered breached if encryption key not compromised.
HexBurn Benefit: ✓ Encryption provides breach safe harbor, ✓ Zero-knowledge = unbreachable PHI
4. Business Associate Agreements (BAA)
Required contracts between covered entities and service providers:
- Define permitted uses of PHI by business associate
- Require appropriate safeguards to prevent misuse
- Require reporting of security incidents and breaches
- Require subcontractor BAAs if applicable
