See what attackers see.
Fix it before they find it.
Tripline scans your SaaS from the outside — front end and back end, across your main site and its app, API, and admin subdomains — then ranks every exposure by severity with the exact steps to close it.

While you ship, they scan.
Attackers don't pick targets by size — they pick by exposure, automatically. The moment your app is public, it's being probed. The numbers are not on your side.
Live secrets — API keys, database passwords, tokens — were leaked into public code in 2025 alone, up 34% in a year. One exposed .env is all it takes.
Growth in one year of attacks exploiting internet-facing edge and VPN devices (3% → 22% of exploited breaches). Anything you expose is being hit.
The median time companies take to patch a known flaw — while vulnerability-based breaches rose 34%. Your exposure window is weeks; an attacker needs minutes.
Of small-business breaches involve ransomware — more than double the 39% rate at large companies. Being small makes you a better target, not a safer one.
Average cost of a single data breach — $10.22M in the US. A startup rarely survives even a fraction of that, plus the lost trust on launch day.
Of leaked secrets are never rotated and stay live for years. The key you exposed months ago may still be opening every door right now.
And then it stops being just your problem. If an attacker reaches your Stripe or Supabase, exposed payment and customer data triggers mandatory breach-notification laws and regulator scrutiny — under GDPR alone, fines reach €20M or 4% of global revenue. A leak becomes a legal and compliance event, not just a technical one.
You can't fix what you can't see.
Show me what's exposed →Front end and back end, every host.
Every check is passive and external — Tripline never logs in, runs exploits, or touches your data. It scans your main site and its app, API, and admin subdomains together, reading only what any visitor can already see.
Certificate & transport
Expired or weak certificates, deprecated TLS 1.0/1.1, missing HSTS, downgrade risk.
Security headers
Missing CSP, clickjacking protection and nosniff, plus dangerously permissive CORS.
Exposed files & keys
Public .env, .git, backups, source maps, and live API keys leaked in your bundle.
Backend & API surface
Exposed Swagger/OpenAPI docs, GraphQL playgrounds, Spring actuator, debug pages, and directory listings.
Domain & mail auth
SPF, DKIM and DMARC gaps that let anyone send phishing mail as your domain.
Exposed surface
Forgotten staging sites, open admin panels, and database UIs reachable from the internet.
Stack & dependencies
Outdated frameworks, CMS versions and front-end libraries with known vulnerabilities.
Every host graded
Main site and each subdomain graded, all findings ranked by severity with a plain-language fix guide. PDF ready.
Safe by design. Honest by default.
The scan is built to be safe to run on a live product and straight with you about what it finds.
Passive & external
We read only what's public. No login, no exploit, no attack on your site.
Secrets redacted
If we find a leaked key, its value is redacted and never stored in plaintext.
No fake findings
We report only what we actually detect, ranked honestly by severity.
Built for founders
One focused tool: external security scanning a non-expert can actually act on.
Every finding comes with the fix.
This is a real example of one finding from a Tripline report — what it is, why it matters, and the exact steps to close it.
Exposed .env file containing a live Stripe secret key
A .env environment file is publicly downloadable at /.env and contains a live secret key.
- Remove the file from the web root immediately.
- Treat every secret it contained as compromised and rotate all of them now.
- Block dotfiles at the server: deny access to any path starting with a dot.
- Ensure .env is in .gitignore and never deployed to the public directory.
