Unified API Security: How Zero-Storage Architecture Protects Customer Data in Real Time
December 5, 2025
Every API connection is a potential risk vector. Integration vendors that store, sync, or cache customer data expand the attack surface, multiply compliance obligations, and complicate incident response.
Unified takes a different approach. We built a real-time, zero-storage architecture designed to safeguard customer data by default — no replicas, no warehouses, no liability footprint.
Zero-Storage Architecture: Eliminating Data-at-Rest Risk
Unified never stores your customers' data. Every API call is fetched live from the source, transformed in memory, and delivered instantly to your system.
Why it matters
Most unified API and iPaaS vendors cache data for convenience. Those caches become secondary databases containing sensitive customer information. If that data is breached or subpoenaed, your users' records are exposed.
By never writing data to disk, Unified removes that liability entirely. No stored data means no additional breach vector and faster compliance reviews.
Compliance by Design
Unified is SOC 2 Type II certified and compliant with GDPR, CCPA/CPRA, HIPAA, and PIPEDA.
Our architecture inherently reduces PII persistence risk, minimizing your audit scope and compliance overhead.
Why it matters
Security certifications validate process maturity, but architecture determines your exposure. Many unified API vendors store or sync customer data, which requires their customers to expand SOC 2 controls to cover a secondary database they don't operate. If that vendor is breached, subpoenaed, or misconfigured, your users' data becomes part of the blast radius.
Because Unified never stores data, our SOC 2 footprint is materially smaller — and so is yours. There's no cached database to include in your own audits, no data-at-rest controls to inherit, and no additional monitoring obligations to manage.

Migrating from storage-based vendors
Teams moving off storage-heavy providers (like Merge) avoid multi-week data extraction and sanitization cycles because Unified has nothing to migrate. Credentials import cleanly, and your data model maps one-to-one or through unified schemas. A lightweight credential export → CSV import process lets you transition safely without replicating any historical customer data.

Encryption and Secrets Management
All data in transit uses TLS 1.2+, and minimal operational metadata is encrypted at rest using AES-256.
Teams can optionally store OAuth2 credentials and API tokens in their own AWS Secrets Manager, giving them full custody of credentials.
Why it matters
Encryption protects data from interception. Allowing you to bring your own secrets vault ensures even Unified can't access customer credentials—ideal for regulated or enterprise environments.
Access and Identity Controls
Unified supports SAML 2.0 and OIDC SSO with Okta, Entra ID, Google Workspace, Ping, and others.
Access can be restricted by:
- IP allowlisting
- Environment-specific API keys (dev, staging, production)
- Per-developer tokens with scoped permissions
Why it matters
Centralized identity management prevents credential sprawl, enforces MFA, and aligns with least-privilege principles. Environment-restricted keys reduce blast radius—an exposed dev key can't reach production data.
Application Security and Testing
Security is integrated throughout our software development lifecycle:
- Every build undergoes static (SAST) and dynamic (DAST) analysis
- Containers and infrastructure are scanned automatically
- Independent annual penetration tests validate the platform
Why it matters
Continuous testing ensures vulnerabilities are identified early. External audits confirm that claims hold up under real-world attack simulation, not just internal review.
Data Residency and Regional Isolation
Unified operates fully segregated environments in the United States, Europe, and Australia.
Enterprise customers can also deploy in single-tenant or dedicated clouds with isolated servers and databases.
Why it matters
Regional segregation helps organizations meet GDPR and other residency requirements while improving latency and resilience. It prevents data from crossing borders unintentionally.
Environment-Restricted API Keys
Unified's latest security feature lets teams bind each API key to a specific environment—development, staging, or production.
When combined with per-user keys and IP allowlisting, this isolates credentials across teams and workflows.
Why it matters
If a credential leaks, its reach is limited to a single environment. This dramatically lowers potential exposure during development or testing.
Built for the AI Era
Our Model Context Protocol (MCP) lets AI models like Claude, ChatGPT, or Gemini act on real customer data without exposing PII.
Only permissioned API objects are made available to the LLM; nothing is stored or retained.
Why it matters
AI agents require real-time data, but exposing full datasets creates privacy risk. Scoped MCP access provides the utility of AI actions with enterprise-grade control.
Security Questions to Ask Any Integration Vendor
Use these questions to evaluate providers and uncover hidden risks:
- Do you store or cache customer data?
If yes, ask where, how long, and under what encryption. - Who controls OAuth credentials and API keys?
Can you host them in your own secrets vault? - Can I restrict API keys by environment or IP?
This limits accidental or malicious access. - Which compliance certifications are active and independently verified?
- How often is penetration testing performed—and by whom?
- Are data regions segregated or shared?
- What is your log retention and redaction policy?
Unified was designed to meet every one of these standards: real-time passthrough, zero data storage, and transparent documentation.
