What usually triggers the call

  • Your SOC 2 or ISO 27001 audit expects a current test.
  • A customer security review will not progress without one.
  • An enterprise deal has made it a condition.
  • Your product has changed and the risk picture needs a fresh look.
  • Your last report was too generic, too noisy, or too hard to action.

02 Recognition

You need a penetration test. You need it to be useful.

Most software companies come to us when a penetration test has become a requirement, not a nice-to-have. The trigger may be compliance. But the value is security.

A good penetration test should find real vulnerabilities, explain the risk clearly, help your team fix what matters, and give customers or auditors confidence that your product has been properly tested.

Atoro runs penetration testing to satisfy the requirement and improve the security of the product, based on more than 200 compliance and security projects delivered for software and digital product companies.

03 The value

A test is only worth doing if it finds what an attacker would.

A penetration test exists to answer one question before someone hostile does: where can your product actually be broken into? The certificate is the reason most companies book the test. Finding the vulnerabilities that would otherwise reach production, or a breach notification, is what makes it worth more than the paper.

Our testers go after the things scanners miss: broken access controls, authentication flaws, business-logic abuse, exposed data, and the chained weaknesses that turn a minor issue into a serious one. Every finding is exploited or validated by hand, rated by the risk it carries to your business, and written up so your engineers can fix it, not just acknowledge it.

You come away with two things that matter: the evidence your auditor and customers need, and a genuinely more secure product.

04 Proof

Engineering-led penetration testing

Atoro combines security engineers, compliance consultants, and auditors with computer science backgrounds. That means the test understands how your product is actually built, and the report speaks to both audiences that matter: your engineers and your external reviewers.

We test how modern software is built and shipped: web applications, APIs, cloud infrastructure, authentication, access control, integrations, and exposed services.

Every finding is validated, prioritised, and explained. You do not get a raw scanner dump. You get security findings your team can understand and fix.

Where an engagement requires a specific accreditation such as CREST, we bring in accredited testing partners and own the scoping, reporting, remediation support, and customer-facing delivery.

05 System

Penetration testing scoped to your product and your reason for testing

A penetration test is only useful if it answers the question that triggered it. Sometimes that is “will this satisfy our audit evidence?”, sometimes “will this unblock a customer security review?”, and sometimes the more important one: “what could an attacker actually exploit?” Atoro scopes each test around your product, your risk, and your commercial trigger.

Web application testing

The application surfaces your users and customers interact with, aligned to OWASP.

API testing

The interfaces, authentication flows, authorisation rules, and exposed endpoints attackers target.

Cloud and infrastructure testing

The AWS, Azure or GCP environment that supports your product, as it is really configured and exposed.

External network testing

Your internet-facing footprint and exposed services.

ISO 27001 penetration testing

Scoped to support your ISMS and the technical vulnerability management evidence your certification auditor reviews.

SOC 2 penetration testing

Scoped to the Trust Services Criteria and the evidence your report needs.

You get a penetration test that improves security, supports compliance, and gives customers confidence.

06 Plan

A managed test from scoping to retest

We run penetration testing as a structured engagement with clear scoping, a defined testing window, and support before and after the test.

1

Scope

Confirm what the test is for, what is in scope, what to exclude, and the timeline that fits your audit, customer review, or product release.

2

Test

Experienced testers run the assessment using manual testing, specialist tooling, and AI-assisted techniques where useful.

3

Validate

Findings are reviewed by human testers, prioritised by risk, and checked for practical impact. We do not pass scanner noise off as a penetration test.

4

Report

A clear report with vulnerabilities, severity, evidence, business impact, remediation guidance, and where relevant, the compliance controls the test supports.

5

Remediate

We support your team in understanding the findings, planning fixes, and answering customer or auditor questions.

6

Retest

Included. We confirm the fixes and provide closure evidence, so the work does not stop at the first report.

What we need from your team

  • One technical point of contact.
  • Access or credentials for the systems in scope.
  • A scoping conversation to agree boundaries and timing.
  • Engineering availability to action findings before the retest.

Your team stays involved where it matters. Atoro runs the test, validates the findings, supports remediation, and owns the report.

07 Price

Clear scope before you commit

Penetration testing should be priced to what it covers, not sold as a vague package.

Before we quote, we scope it properly: what the test is for, the systems and applications in scope, the environment being tested, your timeline, and the reporting requirements for your audit, customer review, or internal security programme.

Your proposal sets out exactly what is tested, how it is reported, what your team provides, and how the retest works.

09 FAQ

Penetration testing FAQs

Is penetration testing required for SOC 2?

SOC 2 does not name penetration testing as a universal line-item requirement, but auditors and customers commonly expect a current test as evidence that you identify and address vulnerabilities. For most software companies it becomes part of the evidence story for vulnerability management, risk management, and customer assurance.

Is penetration testing required for ISO 27001?

ISO 27001 does not mandate it by name, but it is the standard way to support technical vulnerability management (Annex A 8.8) and security assurance. We scope the test to support the evidence your ISMS, auditor, or customer reviewer expects.

What does a penetration test usually cover?

Scope depends on your product and reason for testing. Common scopes include web applications, APIs, cloud infrastructure, external network exposure, authentication flows, access control, and integrations. We agree scope before testing starts so the engagement matches your real environment and the requirement that triggered it.

Do you provide remediation support?

Yes. We do not just send a report and disappear. We help your team understand the findings, prioritise fixes, and prepare for retest, and we help explain the results to auditors or customer security teams where needed.

Is retest included?

Yes. After your team remediates, we retest the fixes and provide closure evidence.

Do you provide an audit-ready report?

Yes. The report is structured for engineering teams, compliance owners, auditors, and customer security reviewers. It includes validated findings, severity, evidence, impact, remediation guidance, and where relevant, mapping to the control or requirement the test supports.

Are you CREST-accredited?

Where an engagement requires a specific accreditation such as CREST, we bring in accredited testing partners and manage the scoping, report, remediation support, and delivery. For the compliance-driven and customer-driven testing most software companies need, Atoro’s own security team delivers the engagement directly.

Do you use AI in penetration testing?

Yes, where it improves the quality and speed of the work. AI helps testers go faster, check more paths, generate hypotheses, and support deeper analysis, but it does not replace human judgement. Our testers validate findings, assess impact, remove false positives, and decide what matters. You do not get automated output passed off as expert testing.

Do you test AI-enabled products?

Yes. Many modern products now include AI components, AI-enabled workflows, or AI-powered features. We scope testing around the real product surface, including the web application, APIs, cloud environment, authentication, data flows, integrations, and AI-related functionality where relevant. As an ISO 42001-certified consultancy, we also understand the governance context around AI-enabled products.

How much does a penetration test cost?

It depends on scope, but to anchor it: a typical test of a web application and its API, with manual validation, an audit-ready report and a retest included, starts at around €3,000. A larger or more complex platform (many endpoints, multi-tenant authorisation, several integrations) sits higher. We scope before we quote, so your price reflects what’s actually tested, and you get the number on the first call.

What happens after the test?

You get the report, remediation support, retest, and closure evidence. Atoro can also support the wider cycle through ISO 27001, SOC 2, internal audit, TrustOps, vCISO, and managed security and compliance services.
