Why check before buying Vanta or Drata?
SOC 2 platforms like Vanta and Drata cost $7,000 to $80,000 a year just to monitor your compliance. When an auditor starts their assessment, the first things they inspect are your public endpoints: missing security headers, open email spoofing loopholes, and unencrypted web forms. Neon Security Scanner finds these gaps in 10 seconds for free, so your engineers can fix them before you hire an auditor.
