MANUAL PENETRATION TESTING FOR WEB, API & INFRASTRUCTURE

Hackers Company Find the paths attackers
can actually use.

We test authentication, access control, business logic and exposed infrastructure.
You receive confirmed findings, reproducible evidence and a remediation plan
your engineering team can work from.

01 / OUR EXPERTISE

Test the controls
your business relies on.

We follow the same paths a real attacker would: from a public endpoint or ordinary user account to sensitive data, privileged actions and supporting systems.

01

Web application
security

We test sign-up, login, password recovery, sessions, role boundaries, tenant isolation, file handling and critical business workflows. Scanner results are manually reproduced before they enter the report.

Web apps SaaS platforms
02

API security
testing

We map API operations and test object-level and function-level authorization, token handling, input validation, rate limits and sensitive data exposure across user roles.

REST APIs Integrations
03

Infrastructure
& configuration

We review internet-facing services, TLS, DNS, cloud and server configuration, exposed administration interfaces and paths that could lead from one weak control to broader access.

Configuration External exposure
Every reported vulnerability includes evidence, impact, a severity rationale and a concrete fix. Define the scope

02 / THE APPROACH

A controlled test.
No mystery process.

The scope, allowed techniques, test accounts, communication path and stop conditions are agreed in writing before testing begins.

01 / SCOPE

Agree what can be tested.

List assets, roles, environments, exclusions and business-critical workflows. Set a testing window and escalation contact. Written authorization comes first.

02 / TEST

Exercise real attack paths.

Combine OWASP-based coverage with manual abuse of authentication, authorization, state changes and business logic. Chain weaknesses where the scope permits it.

03 / VALIDATE

Prove and rate each finding.

Reproduce the issue, remove false positives, capture minimal evidence and score its technical severity with CVSS alongside its business impact.

04 / REPORT & RETEST

Fix it and verify the result.

Walk through the report with engineering and leadership. Retest agreed findings and record each as resolved, partially resolved or still open.

Coverage and reporting mapped to established guidance

OWASP WSTG OWASP ASVS OWASP API Security
CVSS measures technical severity; business priority also reflects your environment and data.

03 / THE DELIVERABLE

One report.
Two audiences.

Leadership gets the exposure, business impact and order of action. Engineering gets the affected endpoint, attack path, evidence, root cause and a fix that can be tested.

  • C-level conclusion and release recommendation
  • Affected asset, endpoint, role and attack preconditions
  • CVSS 3.1 vector plus business impact
  • Reproduction evidence, remediation and retest criteria

04 / ENGAGEMENTS

Start with the question
you need answered.

Scope is built around the assets, user roles, critical workflows and changes that matter to your business. The proposal states exactly what will and will not be tested.

FOCUSED REVIEW

Test one release or risk area.

For one application, API, new feature or workflow with a defined security question.

  • Current attack surface and agreed user roles
  • Confirmed findings with reproduction evidence
  • Technical report and remediation readout
Discuss a focused review

ONGOING ASSURANCE

Retest as the product changes.

For teams releasing often or adding integrations, roles and externally exposed assets.

  • Testing around releases and material changes
  • Focused checks of newly introduced attack paths
  • Open-finding tracking and revalidation
Plan ongoing testing

BEFORE WE BEGIN

Good questions.
Clear answers.

What do you need before testing starts?

A list of domains, applications and APIs; the important user roles and workflows; test accounts where available; and written authorization. We then document the testing window, exclusions, data-handling rules, contacts and stop conditions.

Can you test production safely?

Yes, when production is the agreed target and safeguards are in place. We avoid destructive payloads, denial-of-service activity and uncontrolled data changes. Higher-risk checks are discussed first, and an emergency contact can stop testing.

How is this different from a vulnerability scan?

A scanner flags patterns. A penetration test follows attack paths across roles, authorization decisions and business workflows. Tools support coverage, but every reported vulnerability is manually reproduced and explained in the tested context.

How do you rate findings and verify fixes?

CVSS 3.1 records technical severity. Priority also considers the exposed data, affected users, attack preconditions and operational impact. During a retest we repeat the original attack and related bypass checks, then mark the issue resolved, partially resolved or still open.

START WITH THE SCOPE

Tell us what
needs testing.

Share the assets, user roles, environment and release date or concern. We will reply with the questions needed to define scope, assumptions and a realistic timeline.

Testing is performed only with explicit written authorization and within an agreed scope.
