For startups & SaaS — manual testing

Security audit for startups, without the enterprise invoice.

Startups rarely fail security questionnaires because their code is uniquely bad — they fail because nobody has tested it yet, and the deal cannot wait 6 weeks for an $18,000 engagement. We test your app by hand and give you the report.

How does a startup get a security audit without an enterprise budget? Traditional penetration tests average around $18,000 and begin with weeks of scoping calls. Bug Circuit productizes the same manual work for startup-sized apps: a free critical-bug check (passive, no login), a $49 one-time manual audit with a full written report, or $299 for the audit plus fixes to high and critical issues and 3 months of cover — all with a 14-day money-back guarantee before testing begins.

The email that stalls the deal

It usually arrives right before a signature: your first serious customer’s procurement team sends a security questionnaire, and one line reads “Have you performed penetration testing within the last 12 months? Please attach the report.” You have no security hire, no report, and a deal that can’t wait. Traditional firms quote $5,000–$20,000 and want 2–6 weeks of scoping before a single test runs — small-business “floors” at those firms start around $3,500–$4,000.

What the customer actually needs is rarely a specific firm’s letterhead. They need credible evidence that an independent human tested your application, what was found, and what you did about it. That is exactly what our report is: scope, methodology, verified findings with severity and remediation — written to be shared with the enterprise customer who asked. We wrote a full playbook for handling this request.

What we test in a SaaS application

MVP code ships fast, and the bugs it ships are predictable — not exotic zero-days, but access-control and logic flaws in the features you built under deadline. A human engineer works through them by hand:

  • Multi-tenant access control — can tenant A read tenant B’s data? The single most damaging class of SaaS bug, and the first thing we attack.
  • IDOR (insecure direct object references) — changing an ID in a URL or API call to reach records that aren’t yours: invoices, documents, user profiles.
  • Roles & permissions — member-to-admin escalation, invite and removal flows, whether a downgraded or deleted user keeps access they shouldn’t.
  • Authentication & session handling — password-reset logic, token expiry, whether logout actually invalidates sessions, OAuth and SSO misconfigurations.
  • API surface — undocumented endpoints, mass assignment, missing rate limits on the routes your frontend never calls but attackers will.
  • Business logic — trial abuse, plan-limit bypasses, promo-code stacking, billing-state manipulation.

Notice what those have in common: automated scanners cannot find any of them. A scanner has no idea that user A shouldn’t see invoice B, or that a “member” role shouldn’t reach the billing endpoint — it can only match version numbers and known signatures, and it pads the output with false positives a human has to verify anyway. Here’s the full breakdown of what scanners miss. Sub-$1,500 “pentests” from big-name firms are usually exactly that: a rebranded automated scan.

Honest words about SOC 2

Let’s be plain, because plenty of vendors aren’t: a security audit is evidence of a security practice, not a SOC 2 certificate. SOC 2 is an attestation issued by a licensed CPA firm after examining your controls — no penetration test, at any price, substitutes for it. Anyone selling “SOC 2 in a box” via a pentest is misleading you.

What an independent audit is: one of the concrete artifacts a SOC 2 program expects. Penetration testing is a control most frameworks include, auditors routinely request the latest report, and the enterprise customers pushing you towards SOC 2 will accept credible testing evidence in the meantime. Doing it early also means you fix the auth and tenancy flaws now, on your schedule — not mid-audit, under observation, at panic prices.

Built for startup speed

The slowest part of a traditional pentest isn’t the testing — it’s everything before it. Discovery calls, proposals, SOW redlines, NDAs bouncing through legal. We removed all of it:

The flow: checkout, prove you own the domain (email, DNS, file or meta-tag), sign the recorded Authorization to Test, and a human engineer gets to work. The honest caveat, as always: $49 buys a productized small-app scope, not an enterprise engagement. One web application, focused manual testing of its real attack surface. If you’re running a sprawling platform with mobile apps and fifty microservices, we’ll tell you that before taking your money — not after.

Common questions

Do startups actually need a penetration test?
Not for its own sake — you need one when something demands it: an enterprise customer sends a security questionnaire, a SOC 2 audit is on the horizon, or you start handling data a breach would make existential. In practice, most startups hit that wall at deal time, with a signature waiting on the answer. Testing before that moment is cheaper and far less stressful.
Is a $49 audit enough to satisfy an enterprise security questionnaire?
Usually the questionnaire asks whether independent security testing was performed and requests the report. Our report documents scope, methodology, findings and remediation — written by a human engineer, suitable to share with enterprise customers. The honest caveat: a minority of procurement teams contractually require a named large-firm engagement, and no $49 product changes that. Most just need credible evidence. Here’s how to handle the request step by step.
Does a security audit count towards SOC 2?
It is evidence, not the certificate. SOC 2 is an attestation issued by a licensed CPA firm after examining your controls — no penetration test replaces that. But penetration testing is a control most SOC 2 programs include, and auditors ask for the report. An independent manual audit is exactly the artifact they expect to see.
How fast can a startup get a pentest report?
Testing starts after checkout and domain-ownership verification — there are no scoping calls, proposals or SOW negotiations, which is where traditional engagements lose 2–6 weeks before any testing begins. You get the free passive check results in seconds, and the full manual audit follows a productized process rather than a consultancy queue.
Do you test our production app or staging?
Either. The free check is passive and safe to run against production. For active testing, many startups point us at a staging environment that mirrors production — that works well as long as the auth and tenancy logic is the same. Both require domain-ownership verification and a recorded Authorization to Test first.
What if you find nothing serious?
Then the report says exactly that — and a clean report from an independent tester is precisely what the enterprise questionnaire wanted. In practice, most early-stage apps we look at have at least a few access-control or session-handling issues worth fixing.
