Learning Curve
Though user-friendly, users unfamiliar with encryption concepts might still face a learning curve initially.
Reliance on Proper Key Management
Requires users to manage their encryption keys carefully, which can be a source of security risk if not handled properly.
Potential Compatibility Issues
Despite being cross-platform, there may be occasional compatibility issues with certain file types or software versions.
Lack of Professional Support
As an open-source project, it may not offer professional support, which could be a drawback for business users needing SLA-backed support.

Decentralized Network
The SKS OpenPGP Key server is part of a decentralized network, which means it doesn't rely on a single point of failure and can continue to provide services even if parts of the network go down.
Open Source
The software running on SKS Key servers is open source, allowing users to review the code for security flaws or implement improvements, enhancing transparency and trustworthiness.
Interoperability
The SKS Key server network allows for interoperability with other OpenPGP-compliant software and servers, making it easier to share public keys across different systems and users.
Automated Key Synchronization
Keys uploaded to any SKS server are synchronized automatically across the network, ensuring widespread availability and ease of use for those searching for public keys.

Data Inaccuracy
Since anyone can upload keys, the network can contain outdated or inaccurate data, which could result in trust issues if users find and use invalid keys.
Lack of Key Revocation
Once a key is submitted to the SKS server, it's difficult to remove, including revoked keys, which can continue to be distributed and potentially misused.
Privacy Concerns
The open nature of the server means that uploaded keys and some associated metadata are publicly visible, which can raise privacy concerns for individuals sensitive to exposure.
Limited Metadata Management
The SKS Key server software has limited ability to manage or verify the authenticity of metadata associated with keys, which can impact the trustworthiness of the information provided.
