Keeping PHI safe client-side. The Health Insurance Portability and Accountability Act (HIPAA) protects U.S. health information. A major compliance issue comes from third-party tracking cookies, because they can send PHI to outside vendors without a Business Associate Agreement (BAA) or authorization. With protected health information (PHI) entering through browsers and mobile apps, server-side controls aren't enough. You need client-side visibility and control. cside delivers both and adds audit-ready evidence.
HIPAA focuses on protected health information (PHI). PHI is health information that can be tied to a person: medical history, diagnoses, treatment, insurance details etc. assigned to a name, address or other personal identifier. Tracking cookies on forms can leak those PHI to ads or analytics vendors without a BAA or authorization.
Patients have the right to access their personal information and request corrections. HIPAA also allows certain uses without authorization, for example for treatment or payment. But, if unsecured PHI is breached, affected patients must be informed. That puts real responsibility on organizations. Compliance requires a series of measures: risk analysis, implementing administrative, physical, and technical safeguards, managing Business Associate Agreements (BAAs), as well as document policies and procedures. HIPAA establishes civil penalties tiered with annual caps. PHI leaked via third-party cookies of pixels to outside vendors without a BAA or authorization is a growing HIPAA compliance risk. Even criminal charges may apply, not to mention the devastating reputational fallout.
If your organization handles U.S. PHI, HIPAA applies, no matter your location. HIPAA centers on privacy and security. The privacy rule applies to PHI in any form. The security rule covers administrative, technical and physical safeguards for electronic PHI specifically.
You're expected to prove compliance at any time, with detailed evidence. That means continuous risk analysis and management, activity logging, integrity protection, and secure transmissions. Under the HIPAA, keep documentation for policies and procedures ready for review for six years (§164.316(b)(2)(i)).
Health organizations and patients rely on websites and web apps. Because many processes run in the background it is hard to see the risks without proper tools. When websites use third-party scripts, tracking codes, or have security holes, they create real risks. These tools can collect too much data or leak information before your server security can stop it. cside gives you HIPAA-aligned controls right in the browser, preventing risky code from running. Instead of cleaning up after damage is done, PHI exfiltration attempts are stopped at the source. You get exact and real-time visibility into which scripts touch which fields and where data goes. That gives you detailed, request-level logs and evidence for audits and breach analysis according to audit controls §164.312 and documentation retention under §164.316.
Risky scripts are blocked before they run. cside encrypts data in transcript (TLS) as appropriate to risk and restricts traffic to approved endpoints (BAA). You get automatic alerts on all exfiltration attempts.
Always audit-ready. cside records all scripts and transmissions. You can export detailed logs, destination maps and script inventories. cside delivers all evidence you need.
cside protects your PHI from tampering. It tracks digital fingerprints and immediately alerts you to unauthorized changes. You see exactly what was attempted and when.
cside stops over-collection. It monitors forms and cookies in real time, blocking unexpected data capture. You only collect the minimum health information necessary.
Here's what that looks like in the real world. A patient fills out a health form online. Analytics scripts automatically captured that information in the background. The health organization never knows this is happening. And this violates HIPAA because PHI is shared with a third party without BAA or authorization. It's very common and hard to detect.
With cside, the script is intercepted before it runs and blocked.
Result: no unauthorized data sharing, immediate alerts with detailed logs for breach analysis and audit.
