Use Case Recommendations
Best for: Datashelter
Datashelter is automated backup for Linux servers, databases, VPS instances, bare metal and NAS devices, built around an index-based approach and client-side encryption. The agent — Snaper — installs in about ten minutes and handles file and database backups on a daily or hourly schedule with custom retention policies, incremental transfer, AES-256 client-side encryption and compression, so the provider never sees plaintext. Two features matter more than the schedule itself. Immutable WORM storage means a compromised server cannot delete or rewrite its own backup history, which is the failure mode ransomware actually exploits; and alerting solves the dead-man's-switch problem, with ransomware detection, anomaly detection and data integrity checks that tell you a backup stopped happening rather than leaving you to discover it at restore time. Storage is your choice: bring your own S3 bucket at no charge, or use managed storage. Server segmentation and zero-trust architecture are included at every tier, and cross-region replication and audit logs are listed as coming. There are guides and tooling for MySQL, PostgreSQL, MongoDB, Synology and QNAP NAS units, and the company publishes an unusually substantial sysadmin knowledge base in English and French. Managed services are offered for teams that would rather not run it themselves. The important tier detail is that every backup feature is available on the free plan — only the number of servers changes.
Ideal use cases:
- •Teams or individuals who need aes-256 client-side encryption — the provider never sees plaintext
- •Teams or individuals who need immutable worm storage a compromised host cannot rewrite
- •Teams or individuals who need ransomware and anomaly detection with backup-stopped alerting
- •Teams or individuals who need bring your own s3 bucket free, or managed storage at €7/tb
- •Anyone focused on backup workflows
- •Anyone focused on linux workflows
Best for: Nen
Nen addresses a gap that is not a flaw in TLS so much as the place TLS stops. HTTPS protects a request in transit and does it well, but the moment TLS terminates — at the load balancer, the CDN edge, the serverless runtime — the JSON body sits in plaintext across logs, databases, proxies and every third-party hop. Nen keeps the payload itself encrypted end to end, so the trust boundary moves inward past all of that to the specific code that genuinely needs to read the data. The integration is deliberately small: swap fetch for nenFetch on the client, wrap the route handler with withNen on the server, and the handshake, key rotation, per-request HMAC and replay protection happen underneath, roughly ten lines start to finish. The cryptography is post-quantum by default — ML-KEM-768 key exchange under FIPS 203 with ChaCha20-Poly1305 for the payload — which matters specifically for harvest-now-decrypt-later exposure, since payloads that come to rest as ciphertext in a queue or a database stay protected. Encrypted server-sent-event streaming is supported, along with in-memory, Redis and edge session stores. The site is unusually careful about what it does not claim: it states plainly that the two Nen endpoints necessarily hold plaintext, publishes a threat model and protocol spec, and even links a page arguing that if your only concern is the public transit leg, PQ-TLS already covers you. The SDK is open source with no limits.
Ideal use cases:
- •Teams or individuals who need payload stays ciphertext past tls termination — logs, cdn and proxies see base64
- •Teams or individuals who need ml-kem-768 (fips 203) post-quantum key exchange with chacha20-poly1305
- •Teams or individuals who need drop-in nenfetch client and withnen server wrapper, about ten lines total
- •Teams or individuals who need mandatory per-request hmac and replay protection; encrypted sse streaming
- •Anyone focused on encryption workflows
- •Anyone focused on post-quantum workflows
