TL;DR: AI gateways now sit on the critical path for LLM performance, cost, reliability, and governance, and TruFoundry’s comparison shows why semantic caching, failover, and observability matter more than simple request forwarding. The operational question is no longer which gateway is fastest, but which one preserves control over requests, providers, and agent tool traffic as AI usage scales.

By the numbers:
- Cloudflare reports that cache hits can reduce latency by up to 90% on its AI Gateway.
Questions worth separating out
Q: How should security teams govern API access for AI agents and service accounts?
A: Security teams should treat API access as a governed identity path, not a transport detail.
Q: When does semantic caching create more risk than it saves?
A: Semantic caching becomes risky when reused responses can expose stale, sensitive, or context-specific information to a different identity than the one that generated the original result.
Q: What breaks when AI gateway failover is not governed consistently?
A: Failover can become a privilege bypass if backup providers do not enforce the same authentication, logging, rate limiting, and approval rules as the primary route.
Practitioner guidance
- Define gateway policy per non-human identity Map each service account, agent, and application identity to the exact models, providers, and MCP servers it may reach.
- Separate cache eligibility from authorisation scope Allow semantic caching only for request classes where reused output does not create confidentiality, freshness, or decision-risk problems.
- Mirror security controls across failover targets Ensure every fallback provider inherits the same logging, rate limits, key handling, and approval rules as the primary path.

AI gateways are becoming identity control points as much as performance layers. Once a gateway mediates model and MCP traffic, it influences which non-human identities can reach which providers, tools, and data paths. That means gateway governance now intersects with IAM, PAM, and NHI lifecycle management, not just latency tuning. Practitioners should treat the gateway as a policy boundary, not a transport convenience.
A question worth separating out:
Q: How do teams know whether an AI gateway is actually improving control?
A: They should measure whether the gateway reduces unmanaged keys, improves audit completeness, and enforces consistent access rules across all providers. If teams still maintain ad hoc model credentials, cannot explain fallback behaviour, or lack prompt-level telemetry, the gateway is not yet functioning as a governance layer.
