Penetration Testing Cost for Startups

What is actually driving the purchase

Before talking about budget it is worth being precise about why you are buying, because it determines the scope and therefore the price. In practice there are four triggers.

• An enterprise customer's security review. A procurement or vendor-risk questionnaire asks for a recent independent penetration test. This is the most common trigger and the most time-sensitive, because a contract is sitting behind it.
• A funding round. Technical diligence from Series A onwards frequently asks what independent testing has been done and what came of it.
• A framework. SOC 2, PCI DSS or a regional regime sets a requirement with a date attached. The compliance pages cover what each one expects.
• An incident. Something happened, and you need to know what else is exposed.

Only the fourth is open-ended. The other three come with a specific external party whose requirement you can read, and that requirement is usually narrower than the panic suggests. Get it in writing first.

Realistic budgets by stage

These are the scopes that tend to make sense, not a claim about what you must spend.

Pre-seed and seed

Scope to the single product you sell, authenticated, with its API if it has one. That is a web application engagement, from $500, typically three to five business days. At this stage you almost never need network or Active Directory testing, because you almost certainly do not have a corporate domain worth attacking. Spend the difference on fixing what the test finds.

Series A

The product is larger, there are usually several user roles, and tenant isolation has become a real question because you now have customers who care about it. Still an application-scope engagement, but scoped against the role count and the API surface rather than the smallest possible footprint. If you have moved to a cloud environment with meaningful infrastructure, add cloud testing from $1,500.

Series B and beyond

At this point you typically have a corporate network, an identity provider, and staff with laptops, which means the attack surface is no longer only the product. Network and Active Directory testing from $1,500 becomes genuinely relevant, and an annual programme across both product and infrastructure makes more sense than a single engagement. This is also the stage where phishing and social engineering starts to matter, because you now have enough people to be a target.

Scoping a first test so it unblocks the deal

A first test bought under deal pressure has one job: produce evidence the customer accepts. Three things decide whether it does.

The scope has to match what they asked for. If the customer is buying your SaaS product, test the SaaS product, authenticated, including the boundary between two customer accounts. A test of your marketing website satisfies nobody and the attestation letter will say so.

The evidence has to be complete. Most reviews want a scoped report with severity-rated findings, documented remediation, retest evidence, and a letter attesting to what was tested and when. If any of those is a separate purchase, you will discover it at the worst moment. All four are included in my engagements by default.

The timing has to work backwards from the deadline. Testing is three to five business days for a small application, you then need time to fix what was found, and the retest comes after that. Two weeks end to end is a realistic minimum. Starting the conversation a month out costs the same as starting it a week out and produces a far better outcome.

What to do before the test to get more from it

Every hour the tester spends on something you could have fixed in ten minutes is an hour not spent on the interesting parts of your application. Before a first test, it is worth enabling multi-factor authentication across admin access, removing accounts belonging to people who have left, updating dependencies with known critical vulnerabilities, and making sure test and staging data is not production data. None of this is glamorous and all of it raises the value of what you are buying. There is a longer list in how to prepare for your first penetration test.

Also decide in advance who will fix the findings. The most common failure mode for a startup's first test is not a bad report, it is a good report that nobody has time to act on, which leaves you with evidence of problems and no evidence of remediation. That reads worse to a customer than not having tested.

What it costs with me

Application testing from $500, network and Active Directory or cloud from $1,500, fixed against a written scope with no hourly billing. Remediation support, the retest and the attestation letter are included. You deal with one OSCP+ tester throughout, which at this size is usually an advantage: the person who scoped the work knows your product by the time the report is written.

The general pricing model is on the penetration testing cost page, the sample report shows the deliverable, and if the price range you are seeing elsewhere is confusing, what cheap penetration testing buys explains the spread.
