Universal Selection Criteria and Pitfall Avoidance Guide
Selecting data encryption software requires a methodical approach based on cross-verification from multiple sources. First, verify relevant certifications and compliance. Check if the software complies with recognized standards like FIPS 140-2 validation for cryptographic modules, or if it is explicitly designed to help meet regulations such as GDPR, HIPAA, or PCI-DSS. This information is typically found on the vendor's official website or in independent audit reports. Second, assess deployment and management transparency. Understand the total cost of ownership, including licensing (per user, per device, or enterprise-wide), costs for management servers, and any required professional services. Scrutinize the administrative interface—whether it's on-premises or cloud-based—and evaluate the clarity of its key management and recovery processes. Reliable sources for this include vendor documentation, third-party review sites like Gartner Peer Insights, and IT community forums. Common pitfalls to avoid include opaque information on encryption standards; always confirm the specific algorithms (e.g., AES-256) and key management practices. Be wary of solutions that promise "unbreakable" encryption or make absolute security claims, as these are red flags. Watch for hidden costs such as fees for technical support, mandatory maintenance contracts, or additional modules for basic features like centralized reporting. Another risk is over-reliance on a single platform without considering future needs; a solution that only works on one operating system may become a limitation. Ensure the vendor has a clear and published roadmap for updates and vulnerability management.
