Web Application Penetration Testing Services

Web applications rarely stand alone. Yours has an API behind it, an identity provider beside it, a cloud control plane under it, and often a mobile client in front of it. Attackers move across those boundaries and so do we, under one methodology and one report standard. Splitting asset classes across separate vendors is how cross-domain attack paths stay invisible, because each vendor reports only what fell inside its own scope.

Manual and automated testing for holistic assessment

Automation handles coverage and regression: it enumerates the surface, catches known CVEs, and re-checks what we tested last time. Operators do the work tooling cannot, which is most of the work that matters. A scanner cannot tell that a valid request for order 1338 returned another customer's invoice, because nothing is malformed and the response is a clean 200. It cannot tell that skipping step three of your checkout applies the discount without the eligibility check. Those require someone who understands what your application is for. We will tell you how many operator hours your engagement includes before you sign.

Business logic, where the scanners stop

The OWASP Top 10 is a taxonomy for communicating risk, not a test plan, and treating it as one produces reports that miss the findings unique to your product. We map findings to the Top 10, the API Top 10, ASVS, and CWE because your developers and auditors need those references. But the testing itself pursues authorization boundaries between tenants and roles, multi-step workflows that can be entered out of order, race conditions on balance and inventory operations, mass assignment of fields the client was never meant to set, and price or quantity manipulation. These are the findings that map directly to revenue, and they are the reason executives read the report.

Ethical hacking techniques for real-world risk assessment

We exploit to the minimum depth that proves real impact and then stop, capturing an evidence chain as we go: the exact request, the response, and the reproduction steps. Every finding carries a severity band, a CVSS v3.1 vector string, and business impact written for someone who does not read HTTP. We separate proven from theoretical, and authentication failures from authorization failures, because they get fixed by different people in different ways. Critical findings reach you the day we prove them rather than in the final report, and destructive testing and denial of service are excluded unless you separately authorize them in writing.

Extensive security awareness training

Findings close on verified retest, never on an assertion that a fix shipped, and retesting is inside the engagement price. A program that bills verification separately quietly teaches everyone to skip it, which is how the same finding appears in three consecutive annual reports. We also track recurrence across cycles, because the same class of flaw returning is a process defect in code review or provisioning rather than one careless commit, and it needs a different fix from the one in the finding.

Our Advantage

Why choose BD Emerson’s web application penetration test service

Retesting included, not billed as a change

Our approach extends beyond testing; we become your partner in enhancing your overall system security posture and ensuring compliance with industry standards.

One team across every asset class

Tell us your application count, whether you have multiple tenant types and privilege levels, your release cadence, and any compliance deadline, and we will scope it precisely.

Tested at release, not once a year

You ship weekly; an annual test describes an application that no longer exists. Our continuous program screens each release, tests APIs when the contract changes using specification diffs so effort lands on what actually moved, and runs a full manual assessment quarterly on the applications that carry revenue. The annual report auditors want falls out of that work rather than becoming a separate scramble.

We had a hard time finding the right company to partner with in support of our compliance journey. Some vendors sell the idea that they do the work, but then you end up doing everything. The ambiguity is what killed our last project. BD Emerson’s team has such great technical knowledge and understands the standard so well that they made us comfortable with moving fast. This has led to us closing major enterprise customers that were previously out of reach because of security and compliance.

Tom Watkins

CEO @ AMI AssetTrack

Lead an enterprise initiative to overhaul the organization's technology stack from ecommerce, corporate tech, and corporate security.

Supported ISO 42001 exercise and served as internal auditor.

Rubrik's privacy and compliance team began with the backbone of BD Emerson. BD Emerson supported building out the privacy program, GRC (ISO 27001, SOC 2, CMMC, FedRAMP), and the appsec function.

We needed a partner who could move quickly, without sacrificing precision. BD Emerson brought the expertise, structure, and speed we were looking for. Their team became an extension of ours, embedding themselves across the organization, guiding us step by step, and giving us confidence in areas we hadn’t tackled before. The internal audit they conducted was so detailed that even the external auditors called it out. Achieving ISO 27001 with zero nonconformities says everything you need to know about the quality of the partnership.
