Security Overview

Based on available technical signals, jup.ag shows a strong safety posture, with valid TLS, HSTS, CSP, and no major malware/phishing detections. Independent security audits exist for Jupiter’s underlying DeFi protocols, further strengthening its technical credibility.

SSL/TLS & Encryption

  • HTTPS: Enabled
  • TLS Version: Valid TLS (TLS 1.3) detected
  • Certificate Validity: Active SSL certificate (3 months old at last check)
  • Issuer: Not explicitly listed in sources
  • Mixed Content: No mixed‑content warnings reported
  • Security Headers:
    • HSTS: Present
    • Content Security Policy (CSP): Present
    • X‑Frame‑Options / frame‑ancestors: Present
    • Permissions‑Policy: Missing
    • Cookie HttpOnly: Missing on at least one cookie
    • CAA Records: Not configured
    • MTA‑STS: Not configured

Hosting & Infrastructure

  • Hosting Provider: Cloudflare (inferred from Cloudflare Browser Insights + security headers)
  • Server Location: Not explicitly listed for jup.ag
  • CDN Usage: Cloudflare CDN present
  • Reverse Proxy: Cloudflare
  • Uptime Reputation: No downtime or instability reported
  • Infrastructure Risks: None flagged in automated scans

Malware & Phishing Scan

  • Malware Detection: No major malware detections found for jup.ag
  • Phishing Flags: None reported
  • Blacklist Checks: No external provider warnings
  • Redirect Behavior: No suspicious redirects detected
  • Third‑Party Scripts: Cloudflare + standard analytics only
  • Injection Risks: No suspicious scripts detected

Privacy & Data Handling

  • Data Collected: Likely includes standard web analytics, wallet interaction metadata (common for DeFi dashboards), and basic session data.
  • Tracking Technologies: Cloudflare analytics + typical web application telemetry
  • Cookie Behavior: At least one cookie missing HttpOnly flag (minor risk)
  • Analytics Providers: Cloudflare + GitHub-linked ecosystem signals
  • Privacy Risks: No excessive tracking detected
  • App Permissions: Not applicable (jup.ag is a web interface, not a mobile app)

Breach History

  • Known Data Breaches: None reported
  • Security Incidents: None publicly disclosed
  • Leaked Databases: None found
  • Credential‑Stuffing Exposure: No evidence of exposure

Security Certifications

These apply to Jupiter’s underlying DeFi protocols rather than the jup.ag website itself:

  • Multiple independent audits across Jupiter Swap, Limit Orders, DAO, Perpetuals, and Lend protocols (Offside Labs, Sec3, OtterSec, Mixbytes, Zenith, Code4rena, Certora formal verification)
  • Web security posture:
    • Valid TLS
    • HSTS
    • CSP
    • Frame protection (from Certaris operational security assessment)

Final Safety Verdict

jup.ag is technically safe to use. It has strong encryption, modern security headers, Cloudflare protection, no malware/phishing detections, and extensive third‑party audits for its underlying Jupiter protocols. Minor issues (missing Permissions‑Policy, missing HttpOnly on one cookie, no CAA/MTA‑STS) are low‑risk and common across many web apps.
