Find the weakness.
Understand the risk.
Fix what matters.

Security assessments with clear evidence and practical remediation guidance for the systems you actually run:

  • Web applications and APIs
  • Cloud environments and configurations
  • Application code at the paths that matter

What we test

Assessments

Web & API Testing

Manual testing of web applications and APIs against their real threat model: authentication and sessions, authorisation and object-level access, input handling, and business-logic abuse.

You receive

A report of reproducible findings with exact requests, affected routes and prioritised fixes.

Cloud Security Review

Configuration and architecture review of your cloud environment: identity and access, network exposure, data storage, secrets handling and logging coverage.

You receive

A prioritised list of misconfigurations and risky defaults, each with the concrete change that resolves it.

Application Security Review

Code-assisted review of a specific application or service: how it authenticates, authorises, validates input and handles secrets, focused on the paths an attacker would take.

You receive

Findings tied to specific code paths, with remediation guidance your engineers can act on directly.

Digital Forensics

Investigation after a suspected incident: evidence acquisition and preservation with a documented chain of custody, timeline reconstruction, and root-cause analysis of how access was gained.

You receive

A certified forensic report suitable for legal, insurance and compliance use, plus concrete steps to close the entry path.

Compliance & Certification Readiness

Preparation for HIPAA, PCI DSS, SOC 2 and ISO 27001: gap assessment against the target framework, control design and implementation guidance, and evidence preparation for the audit.

You receive

A gap report mapped to the framework's controls, a prioritised remediation plan, and support alongside your auditor or QSA through certification.

Deliverables

What you receive

01

Executive summary

A plain-language account of what we tested, what we found and what it means for the business, readable without a security background.

02

Reproducible findings

Every finding includes the steps and evidence needed to reproduce it, so your team can verify the issue and confirm the fix.

03

Prioritised remediation

Fixes ordered by real risk, not raw scanner severity, with enough technical detail to implement without guesswork.

04

Retest of fixes

Once remediation lands, we retest the affected findings and update the report to reflect what is actually resolved.

How we work

Approach

  1. Scope

    We agree in writing what is in and out of scope, the test accounts and environments to use, and who to contact if anything unexpected happens. Testing starts only after written authorisation.

  2. Assess

    Manual, methodical testing against the agreed scope. We work carefully in shared environments and flag anything urgent immediately rather than saving it for the report.

  3. Explain

    You receive the report and a walkthrough call. Every finding is explained in terms of impact and fix, not just a CVSS number.

  4. Retest

    After your team remediates, we verify the fixes and issue an updated report stating what was resolved.

More detail on authorisation, scoping and communication on the approach page.

Reporting

How we report a finding

A useful report explains the business impact, proves the issue is real, and tells your engineers exactly what to change. Here is a synthetic example in our format.

Sample finding (not client data)

Missing object-level authorisation on invoice access

TR3-EX-001 · Severity: High · Synthetic demonstration

Any authenticated user can read other customers' invoices by changing an identifier in the URL. Invoices contain names, addresses and purchase history, so this is a direct exposure of customer personal data.

Beyond the privacy harm, this class of flaw usually applies to more than one endpoint. We test related resources and report each affected route, so the fix can be applied consistently.

Who we are

About

tr3labs is the security-testing studio of VaultFifty1, a security-first engineering partner. Assessments are performed by the engineers themselves. The people who scope the work are the people who do it and who walk you through the results.

More about us and VaultFifty1 →

We are developers too. We build and ship production software at VaultFifty1, so our findings come as changes your development team can actually make, and we can pair with them on the fixes when that helps.

We publish real technical research as we produce it, and we do not decorate this site with invented statistics, certifications or client logos.
