Everything you need to ship resilient APIs
One platform for rate limiting, analytics, credentials, and observability — designed for teams that move fast.
Protect every endpoint without touching your code
Define limits by API key, user, or IP with sliding-window accuracy. Shield enforces rules at the edge so abusive traffic never reaches your services.
- Sliding-window and token-bucket algorithms
- Per-route and per-key granularity
- Instant propagation across all edge regions
See exactly how your APIs are being used
Real-time dashboards break down traffic by endpoint, status, and consumer, so you can spot abuse patterns and capacity issues before they escalate.
- Live traffic and blocked-request metrics
- Breakdowns by endpoint, key, and region
- Custom date ranges and exportable reports
Issue, scope, and revoke credentials in seconds
Manage the full lifecycle of your API keys with scoped permissions, expiration policies, and one-click revocation that takes effect immediately.
- Scoped permissions and expiry policies
- Instant revocation with audit trail
- Automatic rotation reminders

Loved by engineering teams
From startups to scale-ups, teams trust Shield to keep their APIs fast, safe, and observable.
Shield cut our abuse-related incidents to zero in the first week. Setup was literally one header — no SDK, no code changes.
Maya Chen
Staff Engineer · Northwind
The analytics dashboard is the first place we look every morning. We spotted a runaway integration before it took down prod.
Diego Alvarez
Platform Lead · Quanta
Scoped keys and instant revocation gave our security team the control they'd been asking for without slowing us down.
Priya Nair
Head of Security · Stackline
We replaced a fragile in-house limiter with Shield and removed hundreds of lines of code. Sub-millisecond latency confirmed.
Tom Becker
Backend Engineer · Voltify
The activity logs are gold during incidents. Full request context, searchable, and exportable to our own warehouse.
Sofia Rossi

Onboarding our whole team took an afternoon. The docs are clear and the edge rollout is genuinely invisible.
