Penetration TestingFind It Before They Do
A penetration test answers one question properly: what can somebody actually do to your application from outside it? We test by hand, from the public address, the way a real attacker would — then we tell you exactly what we found, how serious it is in your deployment, and what to change. Not a scanner export with a logo on the cover.

An automated scanner recognises patterns. It cannot reason about your business. It will not notice that one account can read another account's data, that a login quietly reveals which email addresses exist, or that a development helper route is still answering in production. Those are the findings that matter, and they surface only when a person builds the request by hand, reads the raw response, and compares it against a control request. We use tooling where it helps, but the engagement is human work from beginning to end.
OurPenetration Testing Services
External Black Box Testing
We start where an attacker starts: the public address, with no source code, no database access, and no account. Reconnaissance maps every reachable host, route, locale, and static asset before any active testing begins.
Authentication & Session Testing
Account enumeration, credential handling, brute-force throttling per address and per account, multi-factor enforcement, cookie attributes, and whether logging out actually revokes the session server side rather than just clearing the browser.
Authorisation & Access Control
Whether protected endpoints refuse anonymous callers, whether one account can reach another account's data, and whether a lower-privileged role can cross into a higher one. Grey box testing with supplied accounts where cross-account checks are in scope.
Input Validation & Injection
Cross-site scripting, SQL injection, host header injection, open redirect, path traversal, command and template injection, and how the application behaves on malformed JSON and a deliberately mismatched content type.
API Security Testing
Publicly reachable API routes tested without a session, then with one. Typed error shapes, information disclosure in error bodies, cross-origin policy, rate limiting, and the business logic reachable behind each endpoint.
Scoping & Rules of Engagement
Scope, exclusions, testing window, and the actions we will and will not take are agreed in writing before we begin. Nothing that changes production state, charges an account, or contacts a real user without your explicit sign-off.
Why Partner with NEXHUB
Clients who choose NEXHUB Technology for penetration testing consistently see meaningful, measurable advantages for their business.
Get a Free Consultation- Findings You Can Act OnEvery issue arrives with reproduction steps, the evidence behind it, a CVSS v3.1 vector, and a specific recommendation — not a severity label and a link to a generic article.
- Severity Rated for Your DeploymentWe rate the risk in your application as it is actually configured, not the theoretical maximum for the vulnerability class. That keeps your remediation queue honest and correctly ordered.
- Coverage You Can AuditThe report includes the full test checklist, covering the checks that passed and any we could not complete, with the reason. A report that lists only failures tells you nothing about coverage.
- A Report You Can Hand OverWritten to be read by your board and by your engineers. Executive summary, findings with evidence, a remediation table, and a verification record for every fix.
Questions,Answered
Black box testing is carried out from the public address with no source code, no database access, and no account, exactly as an outside attacker would. Grey box testing adds a test account and, where useful, read access to the schema. Black box shows what strangers can reach; grey box reaches cross-account access, session lifecycle, and the business logic behind the login. Most applications benefit from both, and we usually recommend starting black box and following with a grey box pass.
