OUR OFFER
Threat-resilient assets in the cloud
We secure the cloud environment, both procedurally and technically. Our services protect your data, applications, and infrastructure from cyber threats while ensuring compliance with relevant standards. With continuous monitoring and threat detection, we prevent unauthorized access, data mishandling, deletion, ransomware, and theft, ensuring business continuity.
Secure and resilient AI systems
- Design AI systems with security built in from the start. We help organizations embed security into AI architectures, models, autonomous agents, and business workflows, reducing risk throughout the entire AI lifecycle.
- Catch AI-specific vulnerabilities before attackers do. Our services address risks unique to AI, including prompt injection, sensitive data exposure and unauthorized actions. We simulate how attackers would actually try to abuse your AI systems, not just check boxes against a standard.
- Secure autonomous agents and non-human identities. We help organizations implement governance, access controls, and guardrails that ensure AI agents operate only within their intended scope and permissions.
- Prevent sensitive data from leaking through AI outputs. We test how models and Generative AI (GenAI) systems handle confidential information to close data-leakage paths before they're exploited.
- Integrate security into AI engineering and operations. From AI SDLC and LLMOps to deployment and change management, we help establish secure development and operational practices for AI environments.
- Maintain visibility and control as AI adoption grows. Continuous monitoring, risk management, and security oversight help organizations detect issues early and support the secure operation of AI solutions.
Trusted AI aligned with business and regulations
- Know exactly who's accountable when an AI system goes wrong. We help define clear ownership and accountability models so AI risk doesn't fall into organizational gaps.
- Avoid regulatory penalties under the EU AI Act (European Union Artificial Intelligence Act). We align your AI initiatives with its requirements so compliance is built in, not bolted on afterward.
- Scale AI adoption without losing control over risk. Our risk management processes let you expand Artificial Intelligence (AI) use across the business while keeping exposure manageable.
- Keep humans in the loop where it actually matters. We design human oversight mechanisms so critical AI decisions are never fully automated without a check.
- Manage AI systems responsibly from deployment to retirement. Lifecycle controls ensure models are monitored, updated, and decommissioned safely, not left to drift unmanaged.
- Build the credibility to earn stakeholder and customer trust. By aligning with ISO 42001, the NIST AI Risk Management Framework (RMF), and your internal governance requirements, we help you demonstrate responsible AI use.
Proactive cyberdefense for uninterrupted operations
We protect our clients from cyberattacks by offering 360° Managed Detection and Response (MDR) services that include monitoring, rapid incident response, real-time threat detection, and prevention. We can either establish an MDR team within your organization or manage your company's security via our specialized centers. Combining human expertise and AI-driven automation, we defend you against a wide range of attacks, ensure regulatory compliance, and maintain business continuity.
Control every identity and access point
We deliver end-to-end Identity and Access Management services that centralize digital identities, user access, authentication, and governance across cloud, on-premises, hybrid, and legacy environments. From assessment and architecture to implementation, automation, and support, we help reduce manual work, strengthen security, and maintain audit-ready compliance.
Cybersecurity that adheres to EU standards
We support organizations implementing cybersecurity risk management measures through expert audits, building threat awareness and security policies, and incident management. Our NIS2 compliance services ensure your organization is adequately protected against cyberthreats according to EU law.
Ensuring customer trust through data protection
Our data security services safeguard your customers' confidential information and data through encryption, secure access control, and compliance management in your IT environment. We prevent data leaks, protecting your organization's data, finances, and reputation.
Securing key systems for stable performance
Our OT Security service ensures the integrity and reliability of your critical infrastructure through real-time monitoring, threat detection, and incident response. We safeguard your operational technology (OT) environments with advanced security solutions, minimizing risks and ensuring business continuity. Our experts assess vulnerabilities, implement robust security measures, and provide ongoing monitoring to protect your critical assets.
Cyber resilience for critical devices
We specialize in protecting internet-connected devices, with a strong focus on IoT and medical technologies, where exposing sensitive data may affect human life. Our cybersecurity services identify, monitor, and mitigate risks, ensuring compliance with strict industry standards and laws. When securing your devices, we keep personal and financial data safe from malicious threats while maintaining user trust.
Robust protection for your cloud and endpoints
We enhance the security of enterprise platforms with security solutions such as Microsoft Defender, Microsoft Sentinel and and other M365 suite security solutions. Implementing a Zero Trust approach, we verify every request to minimize the risk of unauthorized access. We provide strong threat protection, real-time monitoring, and AI-driven threat intelligence to quickly detect and mitigate potential risks.
Security frameworks for complete risk control
We establish policies, procedures, and controls through risk management, compliance monitoring, and continuous improvement of security practices. By implementing effective governance frameworks, we help shape a security posture that prioritizes risks based on business needs, ensuring that security efforts focus on your key priorities.
Attack simulations to evaluate security flaws
We simulate real-world attacks via expert penetration testing to uncover vulnerabilities and provide you with precise security insights. We identify potential weaknesses using tools like BURP SUITE and NESSUS, along with custom scripts. Additionally, we conduct thorough security testing according to well established pen testing frameworks such as Penetration Testing Execution Standard or OWASP Web Application Penetration Testing Guide.
