DataLocker SkyCrypt: A Complete Overview of Features and SecurityDataLocker SkyCrypt is a cloud encryption and key management solution designed to give organizations control over their data stored in cloud services. It focuses on simplifying encryption workflows while preserving visibility and compliance, enabling enterprises to protect sensitive information without major disruptions to existing cloud architectures.
What is DataLocker SkyCrypt?
DataLocker SkyCrypt is a platform that provides encryption, key management, and policy controls for data residing in cloud applications (such as Microsoft 365, Google Workspace, Box, Dropbox, and other SaaS or cloud storage platforms). Rather than moving data out of the cloud, SkyCrypt encrypts data in place or intercepts data flows so that organizations retain control of encryption keys and enforce consistent policies across multiple cloud environments.
Core features
- Centralized key management
- SkyCrypt gives organizations a central place to generate, store, and manage encryption keys. Centralized key management helps ensure compliance with regulatory standards and simplifies auditing.
- BYOK and HYOK support
- SkyCrypt typically supports Bring Your Own Key (BYOK) and Hold Your Own Key (HYOK) models, meaning customers can supply and control the cryptographic keys rather than relying solely on a cloud provider’s native key storage.
- Granular access controls and policy enforcement
- Administrators can define policies that determine which users or applications can access decrypted content, enforce role-based access, and integrate with existing identity providers for single sign-on and conditional access.
- Seamless integration with cloud applications
- SkyCrypt is designed to work with popular cloud storage and collaboration platforms, often using APIs or gateway approaches to encrypt files and attachments without disrupting user workflows.
- End-to-end encryption options
- The platform can offer end-to-end encryption for files and messages, ensuring data is encrypted from the point of origin and only decrypted for authorized recipients or systems.
- Automated key rotation and lifecycle management
- To meet security best practices, SkyCrypt automates key rotation and provides lifecycle management features to retire or reissue keys safely.
- Audit logging and reporting
- Built-in logging and reporting track key usage, access events, and administration actions—helpful for compliance audits and forensic investigations.
- Scalability and high availability
- SkyCrypt targets enterprise needs with scalable architectures, redundancy, and failover mechanisms to ensure key availability without single points of failure.
How SkyCrypt protects data (technical overview)
- Encryption methods
- SkyCrypt uses proven symmetric and asymmetric cryptography standards (e.g., AES for data encryption; RSA or ECC for key wrapping and exchange). Data is encrypted using strong, industry-standard algorithms and key sizes appropriate to the use case.
- Key separation and envelope encryption
- Typically, SkyCrypt implements envelope encryption: data is encrypted with a data encryption key (DEK), which in turn is encrypted (wrapped) with a key encryption key (KEK) that the key manager controls. This design reduces exposure of master keys and simplifies cryptoperiod management.
- Client-side vs. gateway encryption
- Depending on deployment, SkyCrypt can perform encryption at the client endpoint (client-side encryption) or within a gateway that encrypts/decrypts traffic between users and cloud services. Client-side provides stronger assurance that plaintext never reaches the provider; gateway models balance usability and control.
- Integration with identity and access management
- Decryption is gated by identity and policy enforcement—SkyCrypt integrates with identity providers (SAML, OIDC, Active Directory) so that access to decrypted data requires valid authentication and authorization, often with conditional checks (device posture, location, etc.).
- Secure key storage
- Keys may be stored in hardened hardware security modules (HSMs) or FIPS-compliant modules, reducing risks associated with key extraction or tampering.
Deployment models
- Cloud-hosted (SaaS)
- For simplicity, some customers choose a cloud-hosted SkyCrypt deployment where DataLocker hosts the key management service. This reduces operational overhead but requires trust in the vendor’s security and compliance posture.
- Customer-hosted / on-premises
- Organizations with strict compliance or sovereignty needs can host the key manager on-premises or in a private cloud. This ensures keys remain within the customer’s control and jurisdiction.
- Hybrid
- Hybrid deployments combine cloud convenience with on-premises key control—common for enterprises that want to protect data in multiple clouds while retaining custody of master keys.
Use cases
- Protecting cloud file storage (e.g., Box, Dropbox, Google Drive)
- Encrypt sensitive files to maintain confidentiality while using cloud collaboration features.
- Securing SaaS application data (e.g., Microsoft 365)
- Encrypt attachments, SharePoint documents, or mailbox items to ensure compliance and limit provider access.
- Regulatory compliance
- Satisfy requirements from regulations like GDPR, HIPAA, PCI DSS, and others by demonstrating key control, encryption, and audit capabilities.
- Third-party vendor risk reduction
- Control key access so third-party cloud providers or contractors cannot access plaintext data without explicit policy allowances.
- Secure file sharing and collaboration
- Maintain encryption when sharing data externally, ensuring only intended recipients with proper keys can decrypt content.
Administration, monitoring, and compliance
- Role-based administration
- Administrative functions can be split among roles to reduce insider risk (separation of duties), with different operators managing keys, policies, and audits.
- Detailed audit trails
- SkyCrypt logs cryptographic operations, key usage, policy changes, and access attempts to provide an evidentiary trail for auditors.
- Compliance certifications
- Customers should verify DataLocker’s certifications (e.g., SOC 2, ISO 27001, FedRAMP) and the underlying infrastructure used for key storage (HSM certifications, FIPS 140-⁄3) to meet regulatory obligations.
- Data residency controls
- Policies may include controls over where keys or decrypted data are processed to comply with data residency or sovereignty requirements.
Performance and user experience considerations
- Latency and throughput
- Encryption adds processing overhead; SkyCrypt designs typically try to minimize latency through efficient cryptographic operations, local caching of keys (with secure constraints), and scalable infrastructure.
- User transparency
- A key goal is preserving user workflows—transparent encryption should allow users to open and edit files in cloud apps with minimal friction, though some features (like server-side search) can be limited by encryption.
- Feature trade-offs
- Strong client-side encryption can limit cloud provider functionality (indexing, previews, server-side scanning). Organizations must weigh security needs against convenience and functionality.
Strengths
- Customer key control
- SkyCrypt’s BYOK/HYOK support gives strong assurance that customers retain control of keys.
- Cross-cloud coverage
- Centralized key management across multiple cloud platforms simplifies governance for multi-cloud environments.
- Compliance-friendly features
- Audit logging, role separation, and key lifecycle controls support regulatory requirements.
Limitations and considerations
- Complexity of deployment
- Managing keys, access policies, and integration with multiple cloud services introduces operational complexity that requires skilled personnel.
- Potential impact on cloud features
- Encrypted content may not be compatible with some cloud-native features (search, indexing, previews); workarounds can add complexity.
- Trust and vendor risk
- SaaS-hosted key management requires trust in the vendor’s security practices; on-premises options reduce but don’t eliminate risk.
- Cost
- Additional licensing, HSMs, and operational overhead can increase total cost of ownership.
