Zapier's IP Problem: Why Whitelisting All of AWS is a Security Nightmare

You've built a Zap that needs to hit an API behind a firewall. The API partner says "just whitelist your IP." Simple enough. Except Zapier doesn't have a static IP address. It runs on AWS us-east-1, spinning up instances on demand across a massive pool of IP addresses.

So you go to the Zapier community forum and find the official guidance: whitelist the entire AWS us-east-1 IP range.

That range covers millions of addresses. And those addresses aren't exclusive to Zapier. Anyone can rent an AWS instance in us-east-1 and hit your firewall from the same IP range you just whitelisted.

Your security team is going to love that.

The problem is structural, not fixable

This isn't a Zapier shortcoming anyone is going to patch. It's how cloud infrastructure works. Zapier provisions compute resources dynamically. The IP your Zap uses today might belong to someone else's workload tomorrow. There's no way to pin it down.

The Zapier community has been asking about this for years. People connect Make scenarios to SQL Server, build Zaps that push data to SFTP servers, wire up WordPress webhooks. Every single one of these integrations eventually hits the same wall: the other side wants a static IP, and Zapier can't give them one.

Some people try the User-Agent workaround. Zapier sends a User-Agent: Zapier header with every request. But user agents are trivial to spoof. That's not security. That's a suggestion.

What you're actually looking for

The fix is a proxy that sits between Zapier and your destination. Your Zap sends traffic through the proxy. The proxy has a static IP. You give that IP to your API partner, your SFTP vendor, your database admin. Done.

QuotaGuard Static gives you two load-balanced static IP addresses. You configure your Zap's HTTP request to route through the proxy URL we give you. Every outbound request from that Zap now comes from one of those two IPs. No more whitelisting entire AWS regions. No more explaining to your security team why you opened the firewall to millions of addresses.

The five questions this answers

"Does Zapier use a single IP address I can whitelist?"No. Zapier uses the entire AWS us-east-1 pool. You need a proxy to get a static IP.

"How do I whitelist Zapier in my WordFence firewall?"WordFence supports IP whitelisting. Route your Zap through QuotaGuard, then whitelist the two static IPs we assign you. No CIDR notation gymnastics required.

"Isn't it a security risk to whitelist the entire us-east-1 range?"Yes. It opens your firewall to any AWS customer in that region. A static IP proxy reduces your attack surface from millions of addresses to two.

"My Zap connects to SQL Server but port forwarding restrictions block it."SQL Server connections need more than HTTP proxying. QuotaGuard's SOCKS5 proxy and QGTunnel handle TCP-level protocols like database connections. You configure the tunnel to map your local port to the remote SQL Server, and traffic routes through your static IP.

"Can I get a static IP for my Zapier webhook sender?"Yes. QuotaGuard proxies outbound traffic from Zapier through a static IP. Your webhook recipient sees a consistent, whitelistable address.

How it works in practice

Setting this up takes about five minutes:

1. Sign up for QuotaGuard Static. You get a proxy URL and two static IP addresses immediately.
2. In your Zap, use a Webhooks by Zapier action (or Code by Zapier) to route your HTTP request through the proxy URL.
3. Give the two static IPs to whoever controls the firewall on the other end.
4. For non-HTTP protocols (databases, SFTP), use QuotaGuard's SOCKS5 proxy or QGTunnel to handle TCP-level connections.

That's it. Your Zaps now have a fixed address. Your security team stops losing sleep. Your integration partner stops asking why your IP changed again.

If you're handling sensitive data

If the traffic you're routing through Zapier involves healthcare data (HIPAA), payment card data (PCI-DSS), or personal data subject to GDPR, you need more than a static IP. You need end-to-end encryption guarantees.

QuotaGuard Shield uses SSL passthrough architecture. Your data is never decrypted at the proxy layer. We can't see it even if we wanted to. Shield also supports TLS 1.2+ enforcement, BAA signing for HIPAA, and US-only or EU-only data residency so your traffic never leaves the jurisdiction your compliance team requires.

QuotaGuard has been providing static IPs for cloud applications since 2013, serving over 34,000 customers on Heroku, AWS, Render, and every major cloud platform. Get started in five minutes.
