Email Security Compliance for Regulated Industries

Frameworks such as DORA, NIS2, GDPR and KRITIS have made the security of business communications a board-level responsibility. Encryption on its own is no longer enough: organizations must be able to show how messages are protected, who can access them, where the data is processed and how keys are governed, including for exchanges that cross borders.

General-purpose email platforms rarely provide that level of evidence. A dedicated encryption service gives compliance, security and audit teams a single point of control and a consistent record.

CloudPGP provides encryption, access-control and audit capabilities that help you meet the communication-security requirements of these frameworks:

No product makes an organization compliant on its own. Whether these measures are sufficient depends on your sector, risk assessment, configuration and contracts, such as a business associate agreement under HIPAA.

Where encrypted email is processed and stored is a governance decision. The Echoworx platform runs secure, high-performance data centers in five regions:

• United States
• Canada
• United Kingdom
• Ireland
• Germany

This regional footprint keeps data close to where organizations and their customers operate, and supports data-residency and cross-border transfer obligations under GDPR and national rules.

• Facilities engineered for security and redundancy.
• SOC 2, PCI DSS and ISO certifications covering physical, system and operational security.
• Strict access controls with continuous review.

Regulators and auditors expect evidence, not assurances. CloudPGP applies encryption through centrally managed policies and records key events, including key generation, certificate issuance, policy triggers and message delivery status.

These records support internal review, incident investigation and audit evidence. See Security Controls for the administration, tenant and logging controls in detail.

Strong encryption is the starting point. The platform relies on established, widely reviewed standards:

• RSA 2048-bit asymmetric encryption;
• AES-256 symmetric encryption;
• SHA-2 hashing for message integrity;
• ANSI X.509 certificates and the S/MIME email protocols.

The Echoworx platform integrates with AWS Key Management Service (AWS KMS), which uses tamper-resistant hardware security modules (HSMs) validated to FIPS 140-3 Level 3. Keys for secure portal, PGP and S/MIME processing are kept in protected HSM memory and are never exposed outside it.

This hardware-backed approach keeps cryptographic material governed at all times and underpins customer key-control options such as Manage Your Own Key (MYOK). See Key Management.

Future quantum computers threaten today’s public-key algorithms, so preparation has to start now. Echoworx is rolling out hybrid post-quantum cryptography based on NIST-recommended algorithms. The rollout covers:

• quantum-safe algorithms for S/MIME, PGP and TLS, ahead of broad industry adoption;
• AES keys managed in AWS KMS to strengthen secure portal and PDF messages;
• hybrid post-quantum TLS protecting calls to the AWS KMS API.

Resilience comes from architecture. The Echoworx platform is built in protected layers:

• Layered network zones, with public access limited to the outermost zone.
• Front-end services isolated from operational components and from the most sensitive assets, such as private keys and hashed credentials.
• Multiple firewalls enforcing strict policies across every segment.
• Intrusion detection with real-time alerts for immediate response.

For regulated institutions, resilience has to be demonstrable. The platform provides:

• Full regional redundancy, with data replicated in real time for disaster recovery.
• Business-continuity and disaster-recovery plans tested at least once a year.
• Continuous governance through documented policies, annual risk assessments and external audits.
• Personnel controls, including background checks, confidentiality agreements and role-based training.

Independent verification matters as much as the controls themselves. The Echoworx platform on which CloudPGP operates holds the following certifications and accreditations:
