WHO WE ARE

In the digital empire, we are the legion.
Legionaria functions as your dedicated, remote cybersecurity department securing your organization through both tactical offensive security and strategic compliance management.

Our strength is a uniquely agile model. For every mission, we deploy an ad-hoc regiment of the world's finest freelance specialists, hand-picked and rigorously vetted for the specific skills you need.
With a presence spanning Europe, the US, and Asia, this structure allows us to seamlessly integrate with your existing team or scale to serve as your complete security command.

We handle the entire operational lifecycle from sourcing the ideal specialists to planning and executing the mission, removing from you the burden of managing multiple providers.

This end-to-end partnership covers everything from high-level strategy to front-line execution. As your Virtual CISO, we establish your security framework and manage compliance. On the front lines, our tactical teams rigorously test your defenses with real-world adversary tactics, executing full-spectrum campaigns to fortify your entire domain.

  • Adaptive

    Specialists are hand-picked for proven expertise in your unique technology stack, industry, and compliance landscape.

  • Proactive

OUR SERVICES

SERVICE PLAYBOOKS

APPLICATION & API SECURITY

Your applications and APIs are the primary entry points to your digital environment. Our specialists conduct a full-scale assessment of your web, mobile (iOS & Android), and API (REST, GraphQL, SOAP) endpoints, using disciplined methodologies like the OWASP Top 10 to uncover critical vulnerabilities. We demonstrate each finding's impact and provide clear guidance for remediation. The engagement concludes with a report built for clarity, featuring a concise executive summary for leadership and an exhaustive technical deep-dive for your engineering teams with proofs-of-concept, diagrams, and actionable guidance.

INFRASTRUCTURE SECURITY

An organization's strength is measured by the resilience of its core infrastructure. Our assessment tests your environment from the outside in, beginning with your external perimeter to identify exposed weaknesses, then moving to the internal network to simulate what a successful attacker could achieve. We give special focus to your Active Directory and wireless networks, as these are critical targets and common entry points. The final report provides a clear, practical picture of your security posture, showing how vulnerabilities could be chained together to compromise your most critical assets.

CLOUD SECURITY

The cloud presents a dynamic new territory where traditional defenses are often insufficient. Our specialists conduct deep assessments of your AWS, Azure, and GCP environments, hunting for the subtle misconfigurations and vulnerabilities that can lead to a breach. With a special focus on containerized workloads and Kubernetes (K8s) orchestration, our mission is to ensure your cloud architecture is securely configured, giving you clear command over your modern infrastructure.

VIRTUAL CISO (vCISO)

Many organizations need senior security leadership but aren't yet ready for a full-time CISO. Our Virtual CISO service provides this expertise on demand, offering a dedicated specialist for the exact time you need—scalable from a few days per month. We lead your security program remotely and within your budget, developing a strategic roadmap, establishing clear policies, managing risk, and ensuring compliance with frameworks like GDPR, ISO, and DORA. This is active leadership designed to build a mature security posture and prepare your organization for an eventual in-house CISO.

SIMULATED TARGETED ATTACK

This engagement is a comprehensive reconnaissance of your organization's entire digital attack surface. Our team systematically assesses every externally exposed asset—from applications and infrastructure to your people via social engineering—to find readily exploitable vulnerabilities. The objective is to uncover and validate weaknesses before an adversary does. Unlike a full Red Team exercise, this assessment focuses on broad discovery, not stealth or evasion of your internal security team. You receive a detailed report that maps your attack surface, catalogs all findings, and provides clear, actionable recommendations.

SECURITY AWARENESS

Your people are the first line of defense and often the primary target. Our Security Awareness programs go beyond standard compliance training to instill discipline and vigilance in your staff. Through a combination of engaging education and realistic phishing and social engineering simulations, we drill your teams to recognize and respond to modern deception tactics. The objective is to transform your employees from a potential vulnerability into a proactive human firewall, creating a security-conscious culture that serves as the bedrock of your defense.
