Authorization testing
Object-level and function-level access control probed across every role and tenant boundary. This is the flaw class behind most API breaches, so it gets the most tester hours.
Cybersecurity · Security Testing
Attackers read your API as the product. So do we.
The security review that stalls a partner integration usually asks one thing your last pentest can't answer: how was the API itself tested? Most products now expose more logic through APIs than through any interface, and the flaws that matter (broken object-level authorization, mass assignment, unbounded queries) never surface in a web scan. We assess the API as what it is: your business logic, exposed and programmable.
Independent quality engineering & cybersecurity since 2020, with 100+ security & quality engineers, delivering on platforms we build and run ourselves.
An API breach is quiet and complete. No browser, no user reports, just enumerable IDs handing over records at machine speed, and by the time misuse registers in your metrics the dataset has already left.

The structure, depth, and remediation detail your team will receive, with client identity and evidence removed. No form, no email: the download is open.
What we do
Input & injection testing
Injection classes, deserialization, and schema-validation gaps across REST, GraphQL, and event endpoints.
Business-logic abuse
Rate limits, workflow bypasses, replay, and enumeration: requests that are valid HTTP and invalid business, which is exactly why scanners miss them.
Auth & session review
Token handling, JWT validation, key management, and session lifecycle, where one mistake is total compromise.
How it’s delivered
01
Map
Inventory built from specs and live traffic, so shadow endpoints get tested along with the documented ones.
02
Test
Manual assessment structured around the OWASP API Security Top 10.
03
Report
Every finding ships with a reproduction request that runs.
04
Retest
Fixes verified, report updated.
Tools & standards
- Tooling
- Burp Suite Pro, OWASP ZAP, Postman, custom harnesses
- Methodology
- OWASP API Security Top 10; PTES-aligned reporting
What you receive
- Findings mapped to endpoints, each with a working reproduction request
- An authorization matrix showing results across roles and tenants
- Remediation guidance written for the team that owns the API
- Retest verification once fixes ship
Evidence
300+ APIs, one program
For one client we assessed more than 300 endpoints in a structured program covering authentication, authorization, rate limiting, and injection, including a chained exploit demonstrated end to end. They finished with their first complete, security-reviewed API inventory.
Customer success →Engagement
Ways to engage the same senior bench
Buy it as a scoped project, embed it in your team, or run it as a managed service. The engineers and the governance stay the same, whichever shape fits.
Point-in-time assessment
One scoped assessment with a full report and one retest: for a release gate, a customer or audit requirement, or an annual baseline.
Standing program
Recurring cycles matched to your release cadence, each closed by a retest, so the newest report is never far behind the newest release.
On-demand scope additions
A new application, API, or environment joins the existing program without re-contracting; scoping starts in days.
Who this is for
- Platform teams whose public API is the product
- Companies whose last pentest was scoped to the web app while the API kept growing
- Teams shipping mobile or partner integrations on shared APIs, with a security review pending
Common questions
Do you test against the OWASP API Top 10?
The assessment is structured around the OWASP API Security Top 10, with broken object- and function-level authorization getting the deepest coverage because that's where real API breaches keep starting.
What about our undocumented endpoints?
API discovery works from specs and live traffic, so shadow and internal endpoints exposed by frontend scripts are mapped and tested along with the documented surface.
Is retesting included?
Remediation of reported findings is verified and the report updated to 'remediated and retested', the wording auditors expect. Retest scope and window are set in the engagement agreement.
How are our data and the findings handled?
Engagements run under NDA, and engineers who handle client data undergo background checks. Findings and reports are shared through channels agreed at scoping and are not retained beyond the period needed to deliver and support the engagement. Data-handling specifics (storage, encryption, retention, and destruction) are documented in your service agreement; see the Trust page for our posture.
One practice, one loop
This is one stage of a single assurance loop: findings become regression tests, and their indicators become live detections, so a problem, once fixed, can’t quietly come back. A stack of separate vendors has no way to close that loop. See how the loop connects →
