hooks.ms is the security plane for every event your systems send and receive. Verify, rate-limit, replay-proof, and observe every webhook in flight — without rewriting a single integration.
Modern software runs on events. Payments, identity changes, deployments, and AI agent actions all move between systems as webhooks. Most of those connections sit outside the firewall, outside the SIEM, and outside any consistent security policy. hooks.ms closes that gap.
Webhooks carry payment confirmations, identity events, deployment triggers, and increasingly, autonomous agent actions. Yet most engineering teams still treat them as plumbing — not as a security-critical surface.
Secrets that haven't changed since the integration was first wired up. Every unrotated key is a liability waiting to be exploited by an attacker who has been waiting patiently.
Nobody checks timestamps. Replay attacks that would otherwise re-trigger payments, refunds, or downstream agent actions pass through undetected because the infrastructure was never built to stop them.
Stack traces, screenshots, and abandoned staging environments are full of webhook endpoint URLs. Inbound payloads are accepted from any IP that knows the path.
Outbound calls fire into the open internet with no visibility when they fail. When something goes wrong, the on-call engineer rarely has the data to figure out what happened.
Malformed, oversized, or unexpected payloads reach your application code unchallenged — creating an entire category of parsing-based vulnerabilities that never needed to exist.
When something goes wrong, the incident report gets longer. Auditors now ask questions about webhook integrity that most organizations cannot answer without manual investigation.
hooks.ms sits between your services and the outside world, terminating, inspecting, and forwarding every webhook your platform sends or receives.
Inbound or outbound traffic enters the security plane
HMAC, JWT, and provider-specific schemes validated instantly
Per-source, per-tenant controls applied before handler
Clean event delivered; full audit trail emitted to your SIEM
hooks.ms is purpose-built for asynchronous event traffic — not retrofitted from a generic API gateway. It understands signature schemes, replay windows, and retry semantics that gateways don't address.
The basic deployment requires only DNS or URL changes. Your handler code runs unchanged. No SDK required for the core flow. Security is added transparently.
Security teams finally get visibility over a traffic class they've historically had to take on faith. Every event classified by source, status, and risk — in real time.
Security profiles ship pre-configured for common providers, compliance regimes, and architectures. Custom rules layer on top using a visual builder or a simple policy language.
Every capability in hooks.ms was designed around the realities of webhook traffic — not request-response API calls.
Validate HMAC signatures, JWTs, and provider-specific schemes from Stripe, GitHub, Slack, Shopify, Twilio, and over a hundred other senders. Rotate signing secrets without downtime. Reject anything that fails before it touches your application code.
100+ ProvidersEvery accepted event is fingerprinted and held in a short-window cache to detect duplicates. Stale payloads outside your configured tolerance are rejected. Replays that would re-trigger payments or downstream agent actions are stopped at the door.
Zero Re-triggersPer-source, per-endpoint, and per-tenant rate limits prevent abuse and accidental floods from misbehaving senders. Configurable burst windows let legitimate spikes through while throttling pathological behaviour.
Per-TenantDefine the shape your endpoints expect once, then let hooks.ms enforce it on every request. Malformed, oversized, or unexpected payloads are rejected with a structured error before reaching your handlers.
Schema-as-CodeSend webhooks through hooks.ms instead of dialling the open internet directly. Every outbound call is signed, logged, retried with exponential backoff, and observable end to end. Failures show up as alerts, not silent data loss.
Full ObservabilitySigning keys, bearer tokens, and provider credentials live inside a hardened, audit-logged vault. Rotation is one click for humans and one API call for automation. Compromised secrets can be revoked instantly across every integration.
Instant RevocationEvery accepted, rejected, retried, and dropped event is logged with full context: source, signature status, latency, response code, payload hash, and the rule that handled it. Streams in real time to your SIEM or data lake.
Tamper-EvidentBaseline volumes, sender geographies, and timing patterns are learned automatically. Sudden shifts — a new IP range hammering an endpoint, a partner sending at 3am for the first time — surface as alerts, not postmortem items.
ML-PoweredFrom zero to fully secured event traffic in under ten minutes. No rewrites. No downtime. No SDK required for the core flow.
Route inbound webhook URLs at hooks.ms and channel outbound calls through it. DNS or URL changes only — your handler code stays exactly as it is. Language SDKs are available for teams that want deeper control.
Defaults exist for common providers, compliance regimes, and architectures. Custom rules layer on top using the visual rule builder or a simple policy language — no security expertise required to get started.
Within minutes, see every event your platform handles, classified by source, status, and risk. Anything suspicious is flagged. Anything blocked is explained. Everything that succeeds is logged for the next audit.
Built for every team that depends on event-driven infrastructure — regardless of industry or scale.
Provider webhooks from Stripe, Adyen, Plaid, and others trigger high-value state changes. A single replayed event can move money or reverse a refund that should have been final.
Customer-configured outbound webhooks are a well-known foothold for SSRF and data exfiltration. hooks.ms isolates that traffic, restricts destination ranges, and gives platform teams a single chokepoint to enforce their security posture.
HIPAA, HITRUST, and similar regimes demand a verifiable audit trail for every system-to-system message that touches protected data. hooks.ms produces that trail automatically and retains it for the windows your compliance team requires.
Autonomous agents now invoke tools and external services via webhooks at machine speed. Traditional rate limits and authentication checks were never designed for that pattern. hooks.ms gives platform teams the controls they need to let agents act without letting them run wild.
Even traffic that never leaves your VPC benefits from consistent verification, rate limiting, and observability. hooks.ms sits on internal hops just as easily as it sits at the edge — bringing the same security posture to every event regardless of whether it crosses a boundary.
Attackers resend captured confirmation events to trigger duplicate payouts or reverse completed refunds. Without timestamp validation and idempotency keys, the application cannot distinguish a replay from a legitimate event.
Verification libraries with known weaknesses are exploited to forge valid-looking signatures. Attackers inject arbitrary payloads that your application processes as legitimate provider events.
In SaaS platforms that let customers configure webhook destinations, attackers point those destinations at internal metadata endpoints and cloud provider APIs to exfiltrate credentials.
Secrets compromised months earlier dwell quietly until an attacker is ready to act. Without automated rotation, organizations have no practical way to know how long a secret has been in hostile hands.
All of them are still working in production environments today. The volume of event traffic is growing faster than the teams responsible for it. Every new SaaS subscription, payment provider, and AI tool integration adds another stream of hooks. The marginal cost of securing each one by hand is no longer absorbable.
hooks.ms exists to make that work tractable again — without requiring every team to become a webhook security specialist.
Native verification profiles and log forwarding for the tools you already run. If a provider isn't on the list, custom rules take minutes to write.
Built and operated against the controls your auditors actually care about. The evidence package most security questionnaires require is generated automatically.
Annual third-party audit against trust service criteria. Report available under NDA for enterprise customers.
Information security management system certified and maintained by an accredited external auditor.
BAA available for covered entities and business associates. Controls designed to meet PHI handling requirements.
EU, UK, and APAC regional data residency options. DPA available on request. Data minimisation by design.
TLS 1.3 for all traffic. AES-256 for stored data. Encryption keys managed per customer in the secrets vault.
Every policy change is versioned and attributed. Every secret rotation is logged with the operator and timestamp. Every event is reproducible on demand.
EU, UK, and APAC regional deployment options for customers with data sovereignty requirements. Control plane and data plane can be operated separately.
We replaced about four hundred lines of bespoke verification code with hooks.ms in an afternoon. The on-call pages from spurious replays stopped that night.
Our auditors used to ask the same five questions about webhook integrity every quarter. Now we hand them an export and the conversation moves on.
Our agents make thousands of outbound calls a minute. hooks.ms gave us guardrails without slowing the agents down. It is the only piece of our infrastructure I have never had to apologise for.
Volume-based pricing that scales with event traffic. Adding engineers never increases cost. Security primitives are not paywalled at any tier.
Median overhead is in the single-digit milliseconds for inbound verification and a similar range for outbound forwarding. Latency budgets and regional point-of-presence selection are configurable per integration, so you can tune the tradeoff between verification thoroughness and round-trip time for your specific requirements.
No. The basic deployment requires only DNS or URL changes. Existing handler code keeps running unchanged. SDKs and policies are opt-in for teams that want deeper control — such as custom claim extraction, dynamic rule overrides, or handler-level event metadata. Most teams are in production within ten minutes without touching a single line of handler code.
The platform runs across multiple regions with active-active failover and a documented uptime SLA on paid tiers. For inbound traffic, an optional bypass mode forwards verified events directly to your origin if the control plane becomes unreachable. This means your event traffic continues — with a brief window of reduced security coverage — rather than dropping entirely.
API gateways are designed for synchronous request-response traffic where the client retries on failure. Webhook traffic is asynchronous, fire-and-forget, and provider-specific. hooks.ms is built around those realities — including provider-specific signature schemes, configurable replay windows, asynchronous retry semantics, and observability designed for events that arrive without a waiting client on the other end.
Pricing scales with monthly event volume rather than with seat count, so adding engineers does not increase cost. Volume-based discounts apply automatically once usage crosses defined thresholds, and enterprise contracts offer custom commitments for predictable spend. You will never pay more because your team grows — only because your event traffic does.
A self-hosted distribution is available for enterprise customers with regulatory or sovereignty requirements that rule out a managed service. The control plane and the data plane can be operated separately for additional isolation — for example, running the data plane inside your VPC while keeping the control plane in a managed environment. Contact the team to discuss your specific architecture requirements.
The hardest part of webhook security is admitting how exposed the surface has been all along. The easiest part is fixing it. Route your first webhook through hooks.ms in under ten minutes — no credit card required.
