Lusentra Security

Offensive security for real-world risk

Find weaknesses before others do.

We run penetration tests with a rigorous methodology and deliver clear, prioritised, ready-to-act reports for both technical teams and management.

  • OWASP, PTES and NIST SP 800-115 methodologies
  • Confidentiality guaranteed by contract (NDA)
  • Executive and technical report, with a remediation plan

Services

Penetration testing tailored to your risk

Every project is adapted to your scope, your sector and the level of risk you want to assess.

Web Applications and APIs

Testing of web applications, REST/GraphQL APIs and business logic.

  • Authentication, sessions and access control
  • Injection, XSS, SSRF and insecure deserialisation
  • Business logic flaws and feature abuse
  • APIs: object- and function-level authorisation, rate limiting

Frameworks: OWASP Top 10 · ASVS · API Security Top 10

Internal and External Infrastructure

Assessment of your Internet-facing perimeter and internal network.

  • Discovery of the exposed attack surface
  • Active Directory, privilege escalation and lateral movement
  • Network segmentation and misconfigured services
  • Credential management and patching

Frameworks: PTES · NIST SP 800-115 · MITRE ATT&CK

Mobile Applications

Static and dynamic analysis of Android and iOS apps and their backends.

  • Local storage and data protection

Methodology

A transparent process, from first contact to retest

We follow recognised frameworks (PTES, OWASP and NIST SP 800-115) and adapt them to every project.

  1. Phase 01

    Scope and authorisation

    We define targets, objectives, testing windows, emergency contacts and rules of engagement. Nothing starts without written authorisation.

  2. Phase 02

    Reconnaissance

    We map the attack surface using passive and active techniques and model the threats most relevant to your context.

  3. Phase 03

    Analysis and exploitation

    We identify vulnerabilities and exploit them in a controlled way to confirm real impact, with no false positives.

  4. Phase 04

    Post-exploitation

    We assess how far an attacker could get: reachable data, privileges obtained and lateral movement.

  5. Phase 05

    Report

    We deliver an executive summary, technical detail, risk rating (CVSS) and prioritised recommendations.

  6. Phase 06

    Presentation and retest

    We walk your team through the results and validate the fixes in a retest.

What you get

  • Executive summary for management
  • Vulnerabilities with severity (CVSS) and proof of concept
  • Prioritised remediation plan
  • Results presentation meeting
  • Retest to validate the fixes

Principles we follow

  • Written authorisation before any test
  • Minimal impact on production services
  • Confidentiality of data and findings
  • Responsible vulnerability disclosure

About us

We think like an attacker so you are always one step ahead

We are a Portuguese team of offensive security specialists.

We work with organisations that need to know, with evidence, whether their systems can withstand a real attack. Every project is led by specialists who combine technical rigour with clear communication.

We believe security is built on transparency: we explain what we do, why, and what you can do next.

Offensive security focus

We do not resell security products. Our advice is always independent and based on the evidence we find.

Reports you can read

An executive summary for management, technical detail with proof of concept and remediation steps for your teams.

Controlled impact

Rules of engagement agreed in writing and techniques chosen to avoid disrupting your services.

Confidentiality

NDA, encrypted communication and secure deletion of data at the end of the project.

Compliance

Evidence for audits and regulatory requirements

Our reports can serve as evidence in audits and compliance programmes. The applicable framework depends on your sector and size.

  • NIS2
  • GDPR
  • ISO/IEC 27001
  • PCI DSS
  • DORA

Frequently asked questions

What is the difference between a pentest and a vulnerability scan?

A vulnerability scan identifies known weaknesses, usually with automated tools. A penetration test goes further: a specialist tries to exploit those weaknesses, chain them together and demonstrate the real business impact, removing false positives.

Can a test affect my production systems?

We plan to minimise risk. Together we define the rules of engagement, time windows and permitted techniques, and we avoid destructive testing. We can also test in pre-production environments.

Do I need to give authorisation?

Yes. We only test systems with written authorisation from their owner. Scope, dates and emergency contacts are recorded before we start.

What do I receive at the end?

A report with an executive summary, a technical description of each vulnerability, risk rating, proof of concept and remediation recommendations. We present the results in a meeting and can validate fixes in a retest.

How long does a test take?

It depends on the scope. The effort and schedule estimate is always included in the quote.

Do you help meet requirements such as NIS2 or ISO 27001?

Yes. We adapt the scope and documentation to your sector’s requirements and provide evidence that can be used in audits.
