Prevent Sensitive Data Leaks from Engineering and Product Teams
Developers, product managers, and IT teams paste credentials, API keys, and internal data into AI tools constantly. Sonomos detects secrets, PII, and proprietary identifiers locally and blocks them before they reach external services.
Start Protecting Your CodebaseWhat Sonomos Detects
Sensitive data patterns relevant to technology that Sonomos identifies in real time.
API Keys & Secrets
Patterns consistent with API keys, access tokens, and secret strings from major providers (AWS, GCP, Azure, Stripe, GitHub, etc.). Detected via prefix patterns, entropy analysis, and structural format matching.
Structural + contextual matchingDatabase Connection Strings
JDBC, ODBC, and URI-format connection strings containing hostnames, ports, credentials, and database names.
Contextual pattern matchingInternal IP Addresses & Hostnames
RFC 1918 private IP ranges and internal domain patterns (e.g., *.internal, *.corp, *.local).
Structural + contextual matchingEmail Addresses & Employee Identifiers
Corporate email addresses and employee ID patterns detected via structural format and domain matching.
Structural + contextual matchingCustomer PII in Bug Reports & Logs
SSNs, credit card numbers, phone numbers, and email addresses that appear in pasted log output, error messages, or support tickets.
Structural + contextual matchingSource Code Identifiers
Proprietary function names, internal package references, and repository paths detected in proximity to code-related contexts.
Contextual pattern matchingRegulatory Relevance
Sonomos identifies pattern matches, not compliance status. The following frameworks may be relevant when detected data types are transmitted unprotected.
CCPA
When personal identifiers (employee or customer PII) are transmitted to a third-party AI tool, Sonomos flags a CCPA relevance signal.
PCI-DSS
When payment card data (e.g., from pasted logs or support tickets) is transmitted to a third-party AI tool, Sonomos flags a PCI-DSS relevance signal.
Trade Secret Protection
While not a regulatory framework with a specific compliance signal, transmission of proprietary source code, internal architecture details, and API credentials to third-party AI tools may implicate trade secret protections under the Defend Trade Secrets Act (DTSA) and state equivalents. Sonomos detects and can block these transmissions.
Signal requirements: A relevance signal requires that (1) data in a specific category was flagged, (2) that data was transmitted unprotected, and (3) the destination matches a relevant classification. Blocked or remediated transmissions do not trigger signals.
Sonomos does not determine whether transmitted data constitutes a trade secret, whether an NDA covers the data, or whether the destination has appropriate security controls. Sonomos identifies patterns. Security and legal determinations require your security and legal teams.
How It Works
Detect
Sonomos scans page content locally for API keys, connection strings, internal IPs, PII in logs, and proprietary code patterns. All processing happens in the browser, not on a remote server.
Alert
Flagged content appears with a traffic-light overlay. Red for structurally validated secrets (AWS keys, Stripe tokens) and PII (Luhn-validated card numbers, SSNs). Yellow for contextual matches (internal hostnames, employee IDs).
Block or Mask
When an engineer pastes a stack trace into ChatGPT or a PM drops customer data into an AI writing tool, Sonomos can intercept the request and mask or block sensitive content before it leaves the browser.
Report
Events are logged locally. Export PDF reports for security incident reviews, SOC 2 audit evidence, or internal policy enforcement documentation.
Why Local-Only Matters for Technology
Engineering teams handle the most sensitive data in any organization: production credentials, customer databases, internal architecture, and proprietary algorithms. A privacy tool that sends this data to its own cloud for analysis is just another SaaS vendor with access to your secrets. Sonomos runs entirely in the browser. Your API keys, connection strings, and source code never touch an external server. There is no new vendor to audit, no new data processor to assess, and no new attack surface to monitor.
Your engineers are already pasting secrets into AI tools. Now you can catch it before it ships.
