# Signitch

*/Startups/Signitch*

## Startup Overview

This service acts as a digital middleware layer that intercepts and verifies incoming webhook cryptographic signatures before they reach internal application servers. It processes inbound traffic continuously to ensure that every payload originates from its claimed source. Engineering teams deploy this layer to automatically drop unverified requests, eliminating the risk of spoofed webhooks triggering unauthorized system actions.

Developers typically rely on manual HMAC implementations or custom API gateways to authenticate external data feeds, requiring continuous maintenance as third-party providers update their security protocols. Instead of burdening core servers with custom logic or routing traffic through external hubs like Svix, this platform isolates the mathematical validation entirely.

The architecture deploys directly at the network edge, providing zero-latency execution for all signature verification. It arrives universally compatible with bespoke provider signing schemes, allowing development teams to safely activate new third-party integrations without writing or maintaining custom cryptographic routines.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- 14-day parallel routing pilot processing 1 million standardized webhooks, aiming to prove sub-5ms latency overhead and zero dropped valid payloads compared to direct origin routing
- 30-day custom scheme integration test validating bespoke cryptographic header extraction at the edge, targeting successful verification without requiring any new middleware on the pilot customer's backend
**Target Metrics**:
- Target: <5ms median cryptographic verification latency overhead globally
- Target: 100% of manual HMAC parsing code eliminated from origin server codebases
- Target: 0 unauthenticated webhook payloads reaching origin infrastructure
- Aim: 100 enterprise SaaS webhook signature schemes supported out of the box
**Target Case Studies**:
- High-volume e-commerce platform migrating from manual Stripe and Twilio HMAC parsing to edge verification, achieving zero unverified origin hits and deleting custom cryptographic middleware code
- B2B SaaS aggregator standardizing 50+ third-party webhook integrations, reducing developer maintenance hours to zero when provider signature schemes change
- FinTech infrastructure provider utilizing Dedicated Edge for isolated compliance boundaries, maintaining strict data privacy via in-memory processing while meeting static egress requirements
**Testimonial Targets**:
- Lead Security Engineer expressing confidence that origin servers no longer process unauthenticated external traffic and sensitive payloads remain completely in-memory at the edge
- Platform Engineering Director praising the centralized scheme updates that eliminate emergency patches when upstream SaaS providers rotate keys or update signature headers
- Principal Systems Architect validating the anycast edge routing reliability, noting that the proxy shields the backend without introducing a measurable latency tax

## Startup Top Risks

**Risks**:
- Severity: existential · Description: A critical vulnerability in the edge verification engine allows forged webhook payloads to bypass security, resulting in downstream exploitation and total loss of customer trust. · Mitigation Status: in-progress
- Severity: high · Description: Webhook providers silently change their proprietary signing algorithms or key rotation schedules, causing widespread false-positive blocks and broken customer workflows. · Mitigation Status: in-progress
- Severity: high · Description: Engineering teams perceive signature verification as a trivial coding task, drastically reducing willingness to pay for a dedicated edge service over manual HMAC implementations. · Mitigation Status: unmitigated
- Severity: moderate · Description: Hard dependencies on specific edge compute runtimes restrict deployment for enterprise customers who mandate strict VPC or on-premise data residency. · Mitigation Status: unmitigated

## Startup Story Brand

**Hero**:
- **Need**: to be the architect of a hardened, leak-proof system, not a debugger of HMAC errors
- **Want**: to secure every incoming webhook without bloating the origin server codebase
- **Identity**: the platform engineer at a scaling SaaS company
**Plan**:
- Step: Select providers · Detail: Choose from a library of 100+ webhook formats or define a bespoke signing scheme for custom integrations.
- Step: Validate traffic · Detail: Route incoming payloads through our global anycast edge to filter out unauthenticated requests instantly.
- Step: Protect origin · Detail: Receive only verified, clean data at your server with zero manual parsing required.
**Guide**:
- **Empathy**: Does your webhook processing still stall during peak traffic because of heavy HMAC overhead?
**Problem**:
- **Villain**: cryptographic sprawl
- **External**: Manually maintaining HMAC parsing logic for Stripe, GitHub, and Twilio in the origin server creates security holes and latency spikes.
- **Internal**: You feel like you are gambling with production security every time a provider updates their signing scheme.
- **Philosophical**: Every platform engineer deserves cryptographic certainty — not a backlog of bespoke header-extraction bugs.
**Success**: Your origin server only sees trusted, pre-verified traffic, eliminating 100% of manual signature logic while maintaining sub-5ms performance globally.
**One Liner**: Every deployment, platform engineers struggle with fragile webhook security. Signitch intercepts and verifies cryptographic signatures at the edge so only trusted data hits your server.
**Positioning**:
- **So That**: eliminate signature parsing logic and prevent unverified traffic
- **Unlike**: manual HMAC implementations
- **For Whom**: platform engineers at scaling SaaS companies
- **Category**: Edge security for webhook ingestion
**Call To Action**:
- **Direct**: Deploy edge verification
- **Transitional**: Review signature scheme library
**Failure Stakes**:
- Compromised origin servers from unverified payloads
- Lost webhooks during HMAC logic failures
- Degraded API performance from crypto latency
**Transformation**:
- **To**: the engineer who hardens the global edge
- **From**: a developer debugging broken HMAC header parsing
**Controlling Idea**: Webhook verification belongs at the network edge, not in the application code.
