> Cloud infrastructure auditing, penetration testing, vulnerability assessment and PCI DSS, SOC2, NIST compliance services by OpenNix

OpenNix provides comprehensive IT security audit services - from cloud infrastructure analysis and penetration testing to PCI DSS, SOC2, and NIST compliance assessment. Over 15 years of hands-on experience securing hybrid environments.

## Full Infrastructure and Cloud Audit

We perform a thorough analysis of your infrastructure and cloud resources - both public and private clouds. The assessment covers network security, access control, authentication, service configurations, and secrets management.

Our approach combines automated scanning with [SecureBaseline Cloud](/en/docs/haas/) and manual expert review. The platform checks compliance against 15+ security profiles (CIS, STIG, PCI-DSS, HIPAA) and detects CVE vulnerabilities using NVD, OVAL, and FSTEC BDU databases.

## Standards Compliance

If your business must comply with security standards - PCI DSS, NIST, SOC2, HIPAA - we help you pass audits and meet regulatory requirements. We identify gaps and provide concrete remediation steps with priority and timelines.

## Methodology

The audit follows recognized industry methodologies: OWASP and PTES for penetration testing, NIST SP 800-115 for technical security assessment, CIS Benchmarks for configuration analysis, and the MITRE ATT&CK matrix for modeling adversary tactics and techniques. This approach keeps results reproducible and covers both configuration and exploitation risks - from misconfigured IAM to realistically exploitable attack chains.

## What the Audit Includes

1. **Cloud infrastructure analysis** - IAM configurations, network policies, data encryption, logging and monitoring
2. **Penetration testing** - external perimeter and internal service penetration testing
3. **Compliance assessment** - PCI DSS, NIST 800-53, SOC2, CIS Benchmarks verification
4. **Vulnerability analysis** - CVE scanning, patch verification, configuration analysis
5. **Detailed report** - prioritized recommendations with severity ratings and remediation timelines
6. **Ongoing support** - assistance implementing recommendations and follow-up scanning

## How the Audit Works

1. **Planning and scope agreement** - define audit boundaries, critical systems, and rules of engagement.
2. **Data collection and inventory** - map cloud resources, services, access paths, and entry points.
3. **Automated scanning** - run SecureBaseline Cloud for profile compliance and CVE detection.
4. **Manual expertise and exploitation** - confirm findings, assess real exploitability and attack chains.
5. **Reporting and prioritization** - classify vulnerabilities by CVSS and build a prioritized remediation plan with timelines.
6. **Re-testing** - after remediation, run a control scan and confirm the risks are closed.

## Our Tools

We use our own platforms to automate audit workflows:

- [SecureBaseline Cloud](/en/docs/haas/) - automated CIS compliance scanning and Linux server hardening
- [Wazuh SIEM](/en/docs/yc/wazuh/) - security event monitoring and intrusion detection
- Specialized [detection rules for Yandex Cloud](/en/opensource/) covering 63 cloud services
