GCP external penetration testing. Self-serve, started today

Find what's actually exposed in your GCP project.

Public GCS buckets, internet-facing Compute Engine or GKE workloads, and credentials left sitting in exposed config are common, exploitable gaps in real GCP environments. We manually test your GCP footprint for exactly what an attacker can reach without credentials — not just what a config scanner flags. Start online, no scoping call.

Why GCP teams end up here

GCP's flexibility makes exposed storage and workloads easy to miss.

Public GCS buckets, internet-facing Compute Engine or GKE workloads, and credentials sitting in exposed config are common, well-documented ways into a GCP project — and a generic vulnerability scan mostly misses them. This engagement tests your GCP environment for exactly what's reachable from the internet: exposed services, storage, and secrets, tested the way an attacker actually would.

What audit-grade means

Five commitments that separate a real pentest from a quick-find scan.

"Audit-grade" is a category, not a slogan. It means the report holds up to your auditor's review, your prospect's security team, and your insurance underwriter — not because we say so, but because of what we commit to do on every engagement.

Exposed storage & secrets

Public GCS buckets and credentials or API keys sitting in public-facing config get tested directly — the way an attacker would actually find them.

Internet-facing workload testing

Compute Engine, GKE endpoints, and management consoles reachable from the internet are tested for real, exploitable exposure — not just an open-port list.

Retest from scratch

When you remediate, we retest everything from scratch, not just the listed findings. New issues that surfaced since the original test get reported too.

Honest pricing

Published list pricing by the number of assets you want tested. No quote, no negotiation, no sales-rep discount theater.

Self-serve, no calls

Answer a few quick questions, purchase, and receive your report. No scoping call, no sales rep, no procurement-cycle drag.

Coverage, not quick wins

Bug-bounty and PtaaS testing chases quick wins.
A real GCP pentest is graded on coverage, not the first finding.

The cheap pentest options inside compliance platform marketplaces optimize for time-to-first-finding. They're excellent at surfacing the obvious. They're not designed to comprehensively test what's exposed across your GCP footprint.

Quick-find testing

Bug-bounty and PtaaS researchers race for the first finding. Coverage of the rest of your GCP footprint isn't the goal of the system, and it isn't what gets reported.

Scanner-only testing

Automated config scanners find what they recognize. Exposed storage buckets, leaked secrets, and non-standard workloads are frequently missed.

Audit-grade testing

Every service on every in-scope GCP asset — storage, compute, GKE, management interfaces. If you list it, we test it.

Honest pricing

Published rates. No quotes. No sales calls.

GCP environments range from a single Compute Engine instance to multi-project organizations. Pricing scales with the number of hosts, IPs, or cloud endpoints you want tested.

How pricing works: The first asset covers the essential work every engagement requires — scoping, setup, validation, and reporting. Pricing scales with your environment from there. Count each public-facing host, IP, or cloud endpoint you want tested — they don't have to be contiguous or in the same network. If you have more than 256 assets, contact us.

GCP Pentest FAQ

What GCP teams ask before they buy.

Do you review our GCP IAM configuration directly, or only what's internet-facing?
Only what's internet-facing. This is external penetration testing: public endpoints, exposed storage, internet-reachable workloads, and any credentials or secrets an attacker could find without logging into your project. We don't log into GCP IAM or review bindings directly — that's a separate, credentialed engagement we don't offer today.
Will this affect production?
We scope timing and methods to minimize disruption and coordinate on higher-risk testing in advance.
How long does it take?
There's no sales queue to wait on — scoping starts as soon as you check out; duration scales with scope, and we'll confirm your specific timeline before testing begins.
Do I need a sales call?
No. Choose your scope from the pricing table and checkout online.
What if I need a retest after remediation?
We retest everything from scratch, not just the listed findings. Free retest within 14 days of report delivery. From day 15 through day 60, retest is 25% of the original price. After 60 days, a full re-engagement is recommended because the environment has typically drifted.
Can our procurement team approve this without a custom SOW?
Yes. Pricing is fixed and published. The standard authorization and rules-of-engagement are in our Terms of Service — most procurement teams clear it in days, not weeks. If your process specifically requires a Statement of Work, select that option at signup and we'll send it for signature through DocuSign instead of running payment through Stripe.
