The missing trust layer for incoming data
Every cloud has storage, compute, and queues — but nothing that understands what's inside incoming files. Uplint is the trust layer that sits between the outside world and your infrastructure — verifying, understanding, and securing every file before it enters your system.
S3 stores bytes. It has no idea what's inside them.
You have firewalls for your network and WAFs for your endpoints — but zero trust for the data itself. Files land in your storage unchecked, unverified, and misunderstood. Here's what slips through every day.
Uplint is the trust boundary for incoming data — every file is understood, verified, and secured before it touches your infrastructure.
Understand, verify, and trust every file
Uplint doesn't store your files — it understands them. Deep content analysis, structural validation, threat detection, and audit logging as a single managed layer. The infrastructure primitive your upload pipeline is missing.
Intelligent Blank Detection
Catch the files nobody else catches. Uplint reads into the actual content — detecting PDFs with zero readable words, spreadsheets with headers but no data, single-color images, and text files filled with whitespace.
Threat Scanning
Automatic malware detection on every upload. Part of the pipeline — not a bolt-on. Infected files are rejected before they touch storage.
One API Call
No orchestration needed. One call triggers validation, blank detection, scanning, and logging.
// One call. Full pipeline.
const result = await uplint.validate(
file,
{
context: "patient-records",
scan: true,
detectBlanks: true
}
);Context-Based Rules
Profile photos need different rules than legal documents. Define validation contexts per use case — types, sizes, scanning depth.
Complete Audit Trail
Every file operation logged with full context. Who uploaded what, when, what was validated, what was flagged.
The Full Pipeline
Validation, blank detection, threat scanning, and audit logging — all happen automatically on every upload. No separate services to wire together.
One API call triggers the entire pipeline automatically
See what your current validation misses
Run uplint on your uploads folder or directly against your S3 buckets. See how many blank PDFs, corrupt images, and invalid files are already in your system.
The CLI is how developers discover they need Uplint.
Meet the platform
The CLI catches problems locally. The platform gives you everything you need for production — a security dashboard, analytics, audit logs, and API key management. All included in the free tier.

Security Dashboard
See every threat caught in real time. The moment Uplint flags a malicious upload, you'll know — with full context on what was detected and why.
Upload Analytics
Understand your upload patterns. Volume trends, file type breakdowns, rejection rates, and peak usage — all without setting up separate monitoring.
Audit Logs
Complete history of every file operation. Who uploaded what, when, what was validated, what was flagged. Compliance-ready from day one.
API Key Management
Scoped API keys with granular permissions. Create keys for different services, set rate limits, and revoke access instantly.
500 uploads/month · 1 GB storage · 3 contexts · Full dashboard access
Built for teams that handle sensitive files
Multi-tenant by design, not by afterthought. Uplint was built from the ground up for SaaS platforms processing sensitive uploads across healthcare, finance, and legal.
Multi-Tenant Architecture
Per-tenant contexts, isolated quotas, and separate S3 credentials. Enterprise-ready from day one — not bolted on later.
End-to-End Encryption
Data encrypted at rest and in transit. Your files are protected at every stage of the pipeline.
Bring Your Own Bucket
Use your own AWS S3 credentials and buckets. Uplint validates and scans — your data stays in your infrastructure.
Full Audit Logging
Complete visibility into every file operation — uploads, validations, scans, rejections. Ready for compliance review.
Every blocked upload tells a story
Threat actor profiling, behavioral pattern detection, and cross-entity investigation — built into your dashboard. See the bigger picture behind every blocked file.
Frequently asked questions

They're file storage and CDN services. We're not. Uplint is a file validation and security layer — it sits in front of your uploads and validates integrity, detects blank content, scans for threats, and logs everything. You keep using your own storage (S3, GCS, whatever). We make sure what gets stored is legitimate.
Your stack has a missing layer
You don't build your own compute layer. You shouldn't build your own data intake layer either. Start free — the free tier is the real product, not a trial.
