SaaS / API Deployment
Commercial model APIs, managed infrastructure, fast time-to-value. You focus on the agent logic — the provider handles the compute.
Security Surface
API-based deployments shift infrastructure responsibility to the provider but introduce data transit risks and third-party trust dependencies.
API Key Exposure
API keys are the single point of authentication to commercial model providers. A leaked key grants full access to your account — including billing, usage history, and the ability to run arbitrary prompts under your identity.
Data in Transit
Every prompt and response crosses the public internet to reach the provider's API. Even with TLS, the data is decrypted at the provider's endpoint. Sensitive business data — customer records, financial data, proprietary content — is exposed to the provider's infrastructure.
Prompt Injection
Commercial APIs have stronger built-in guardrails, but prompt injection remains a risk. Attackers can craft inputs that manipulate the model's system prompt, extract instructions, or cause unintended actions through connected tools.
Provider Trust & Data Retention
Your data passes through the provider's systems. Even with zero-retention policies, you're trusting the provider's infrastructure security, employee access controls, and compliance claims. Provider policy changes can affect your data handling retroactively.
Third-Party MCP / Integration Risk
When agents connect to external SaaS tools via MCP or APIs, each integration is a potential data exfiltration path. A compromised integration can siphon data or inject malicious responses.
Vendor Lock-In
Not a direct security vulnerability, but tight coupling to a single provider's API creates operational risk. Provider outages, pricing changes, or policy shifts can disrupt your system with no fallback.
Why SaaS / API?
Zero Infrastructure
No GPUs to provision, no servers to maintain, no model updates to manage. Sign up, get an API key, start building.
Frontier Models
Access to the most capable models (Claude, GPT-4, Gemini) that aren't available as open-source. Stronger reasoning, better instruction following, built-in safety.
Fast Iteration
Switch models, test new capabilities, and scale instantly. No redeployment needed — just change an API call.
Managed Security
Provider handles model security, inference hardening, and compliance certifications. You inherit their security posture for the inference layer.
