Use Case Recommendations
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
Best for: ZeroDrift
ZeroDrift is a compliance firewall for AI. It validates every AI message, agent output and outbound communication against a firm's regulations, internal policies and security controls, and anything that fails is rewritten or blocked before it reaches a customer, an employee or a regulator. The platform is built from five components: Anchor holds the compliance model, Policy encodes regulations and firm-specific rules, Gateway enforces those rules for AI agents, Guard applies them inside everyday tools like email, chat and documents, and Command provides live oversight and controls across the firm. The design intent is one firewall covering every AI surface — agents, chat, systems, email and docs — instead of a separate review process per tool, which is how most regulated firms currently fail: the governed channel is covered and the copilot someone installed last week is not. Named verticals are financial services, insurance and healthcare, plus general enterprise communications, with dedicated views for compliance, security, AI leadership and engineering. Engineers can drop it in front of any LLM. The company raised a $10M seed round covered by TechCrunch and access runs through a booked demo. ZeroDrift is a six-person team reporting $150K ARR growing at more than 50% month over month, and publishes separate solution pages for compliance, security, AI leadership and engineering audiences.
Ideal use cases:
- •Teams or individuals who need validates every ai output against regulations and firm policy
- •Teams or individuals who need rewrites or blocks failing messages before they send
- •Teams or individuals who need five components: anchor, policy, gateway, guard and command
- •Teams or individuals who need covers agents, chat, email, docs and internal ai systems
- •Anyone focused on compliance workflows
- •Anyone focused on ai governance workflows
