We review identity management processes, authentication mechanisms, user provisioning, and access control practices across the organization. This review helps reduce the risk of unauthorized access and strengthens protection of business-critical systems and information assets.
Identity deliverables
- An analysis of privileged accounts, permissions, and user access flows;
- Recommendations for strengthening authentication and least-privilege principles;
- An action plan addressing identity-related security risks.
We assess how critical data is collected, processed, stored, and shared across systems and business processes. The assessment helps improve data privacy, reduce the risk of a data breach, and strengthen alignment with regulatory obligations.
Data protection outputs
- A review of sensitive data flows and storage locations;
- Recommendations covering encryption, retention, and protection controls;
- An improvement roadmap supporting GDPR, HIPAA, and privacy compliance initiatives.
We evaluate vendors, suppliers, and external service providers that may introduce risk into your environment. Organizations gain greater visibility into third-party exposures and stronger supply chain risk management capabilities.
Vendor assessment outputs
- Vendor security profiles and risk rankings;
- Recommendations for managing third-party security obligations;
- A monitoring framework for high-risk suppliers and service providers.
We review information security policies, governance processes, incident response procedures, and operational security practices. The result is a more consistent security program that supports compliance, accountability, and business continuity.
Governance improvements
- An assessment of policy coverage across key security domains;
- Recommendations for improving governance, risk and compliance activities;
- Updated process guidance and a practical security program plan.
We analyze security architecture, platform configurations, and monitoring capabilities to identify weaknesses that affect resilience and operational effectiveness. This creates a stronger security posture supported by well-defined standards and sustainable security practices.
Architecture recommendations
- A security architecture review covering critical systems and integrations;
- Configuration management recommendations aligned with industry standards;
- A roadmap for improving monitoring, detection, and long-term risk management.

Business benefits of a cyber security audit
How a cyber security audit strengthens security, compliance, and resilience against evolving cyber threats
Who needs an IT security audit
Industry-specific security challenges, compliance requirements, and cyber incident risks often drive the need for a cyber security audit.
Fintech and financial services
Financial institutions face growing pressure to meet SOC 2, PCI DSS, and other compliance requirements while protecting sensitive customer data. A cybersecurity audit helps identify control gaps, strengthen security posture, and prepare for regulatory reviews.
Manufacturing and logistics
Manufacturing companies rely on interconnected systems, operational technology, and complex supply chains that create unique security risks. A security audit helps improve visibility, strengthen defenses, and support supply chain risk management efforts.
SaaS and software companies
Enterprise customers increasingly require SOC 2 reports and detailed security questionnaires before signing contracts. A cybersecurity audit helps SaaS providers validate security controls, address gaps, and accelerate sales cycles.
Government contractors
Government contractors handling sensitive information are often required to comply with NIST 800-171 and CMMC requirements. An audit helps assess current controls, identify deficiencies, and prepare for formal assessments.
Healthcare and life sciences
Healthcare organizations must protect patient information and maintain compliance with HIPAA requirements. A security audit helps reduce data breach risk, improve access control, and strengthen incident response readiness.
