Securing Client Intake Portals Without Killing Conversion

Why intake is the soft target

A prospective client form often collects more sensitive information than the first attorney meeting — and it sits on a marketing-team CMS with no WAF, no rate limiting, and a webhook that emails plaintext to a shared inbox.

The fix without the friction

  • Terminate uploads at a storage bucket with server-side encryption and short-lived signed URLs.
  • Strip metadata from uploaded documents before they reach the case management system.
  • Rate-limit by IP and ASN; do not require a CAPTCHA on the first field.
  • Send a webhook, never an email, to a case management system that enforces RBAC.

Measure what matters

The conversion-killers are page weight and form length, not security controls. Done right, hardening adds zero perceived friction and removes the single largest data-loss vector at most firms.
