General Selection Criteria and Pitfall Avoidance Guide
Selecting file encryption software requires a methodical approach based on verifiable principles. First, assess the encryption standards. Reliable software should use strong, peer-reviewed algorithms like AES-256. Cross-reference this information with official documentation or independent technical reviews from reputable cybersecurity sources. Second, evaluate the deployment and management model. Determine if you need full-disk encryption, file/folder-level encryption, or container-based solutions. For businesses, consider central management capabilities, integration with existing directory services (like Active Directory), and recovery options for lost passwords or keys. Third, scrutinize the vendor's transparency and update history. Prefer solutions with a clear record of regular security updates and patches. For open-source software, an active development community and available audit reports (e.g., the independent audit of VeraCrypt) are strong indicators of reliability. Common pitfalls to avoid include information opacity. Be wary of software that does not clearly disclose its encryption methods or has a history of security vulnerabilities that were not promptly addressed. Another risk is hidden costs or restrictive licensing. Free versions may lack critical features like technical support or management consoles, while some enterprise licenses may have complex per-user or per-device pricing that escalates costs. Avoid solutions that make unrealistic promises, such as "unbreakable" encryption, as this contradicts the established principles of cryptography. Always test software in a non-production environment to evaluate its usability and performance impact on your specific workflow.
