Elite penetration testing & red team operations — adversary simulation at scale

Levantis Cyber delivers advanced penetration testing services, red team operations, and cyber security assessments for organisations that require real-world assurance — not theoretical compliance.

We simulate genuine real-world adversaries to identify exploitable weaknesses across applications, infrastructure, cloud environments, and human attack surfaces.

WHY SECURITY
TESTING MATTERS

Cyber threats are not theoretical. Every week, organisations across every sector face breaches that could have been prevented. The question is not whether you will be targeted — it is whether your defences will hold when you are.

Penetration testing gives you the evidence you need to prioritise investment, meet compliance obligations, and protect your organisation with confidence — by exposing real weaknesses before a real attacker does.

Regulatory frameworks including PCI DSS, ISO 27001, Cyber Essentials Plus, and GDPR increasingly mandate regular security testing. Beyond compliance, independent security assessment is the only way to gain objective assurance that your controls actually work.

STRUCTURED
ASSESSMENT METHODOLOGY

Every engagement follows a rigorous, repeatable process adapted to your environment and objectives — whether that's a penetration test, web application assessment, or configuration review.

01

Scoping & Objective Definition

We work with you to define clear engagement boundaries, success criteria, and rules of engagement. Understanding your environment, risk appetite, and priorities shapes every decision that follows.

02

Reconnaissance & Enumeration

Systematic discovery of assets, services, versions, and configurations relevant to the engagement type — network hosts and exposed services for infrastructure assessments, application endpoints and authentication flows for web apps, and security baselines for configuration reviews.

03

Vulnerability Identification & Analysis

Manual-led analysis to identify exploitable vulnerabilities, misconfigurations, and design weaknesses. Automated tooling is used to ensure coverage, but every finding is validated by hand to eliminate false positives and confirm real-world exploitability.

04

Exploitation & Impact Demonstration

Where in scope, vulnerabilities are safely exploited to demonstrate genuine business impact — whether that is unauthorised data access, privilege escalation, lateral movement across a network, or evidence of a security control gap identified during a configuration review.

05

Reporting & Remediation Guidance

Clear, evidence-based reports written for both technical and executive audiences. Every finding is risk-rated in business context, with prioritised remediation steps. Debrief sessions and retest are included as standard.

WHY LEVANTIS CYBER

01

Operators, Not Consultants

Our team comes from offensive security backgrounds — former red teamers, vulnerability researchers, and exploit developers. We think like attackers because we are attackers.

02

Bespoke Engagements

No templated assessments. Every engagement is designed around your specific threat model, environment, and objectives — delivered by a dedicated team, not rotated staff.

03

Actionable Reporting

We write for your audience — clear executive summaries and deep technical detail. Every finding includes evidence, remediation steps, and contextualised risk ratings.

04

Ongoing Partnership

Retesting, vulnerability disclosure support, and strategic advisory included. We stay engaged beyond the report to ensure findings are genuinely closed — not just noted.

TRAINED AGAINST
REAL ADVERSARIES

Our consultants continuously train against the tactics, techniques and procedures (TTPs) employed by today's most capable cyber threat actors — including nation-state groups, ransomware operators, and advanced cybercriminal organisations.

By aligning our assessments to real-world adversary behaviour and the MITRE ATT&CK framework, we help organisations understand how well their people, processes and technology would perform against modern threats.
