What's Included
Infrastructure Security Audit
Comprehensive security audit of servers, network devices, endpoints, and security infrastructure. We evaluate patching levels, hardening configurations against CIS benchmarks, access controls, network segmentation, logging practices, backup verification, and physical security controls — producing findings with severity ratings and remediation effort estimates.
Cloud Security Assessment
Configuration review of AWS, Azure, and GCP environments against CIS Cloud Benchmarks using AWS Config, Azure Policy, and GCP SCC. We check IAM policies, network security groups, encryption settings, logging configuration, storage permissions, and service-specific configurations across all accounts and subscriptions.
Security Architecture Review
Holistic evaluation of your security architecture: network design and segmentation strategy, defense-in-depth layers, monitoring and detection coverage, incident response capabilities, security tool effectiveness, identity architecture, and data protection controls — identifying systemic weaknesses that individual component assessments miss.
Compliance Gap Analysis
Map your current security controls against specific compliance requirements — ISO 27001 Annex A, NIS2 Article 21, NIST CSF, SOC 2 Trust Service Criteria, PCI DSS, or HIPAA. Our gap analysis identifies exactly which controls are missing, partially implemented, or need improvement with prioritised remediation timelines.
Security Maturity Scoring
Benchmark your security programme against industry peers using NIST CSF maturity tiers or CMMC levels. Receive a detailed maturity scorecard across all domains — governance, identity, protection, detection, response, recovery — with a phased improvement roadmap and resource requirements per maturity level.
Digital Forensics & Investigation
When incidents occur, we provide forensic investigation services: evidence preservation following chain-of-custody procedures, disk and memory forensics, attack chain reconstruction, root cause determination, indicator of compromise extraction, and comprehensive documentation suitable for legal proceedings or regulatory reporting.

Security Starts With Knowing Where You Stand
You cannot protect what you do not understand, and most organisations have significant blind spots in their security posture. Unpatched systems, misconfigured cloud resources, overly permissive access policies, disabled audit logging, and legacy systems with known vulnerabilities create an attack surface far larger than most security teams realise. A thorough IT security assessment reveals these gaps systematically — before attackers find them in your next breach. This is a point-in-time audit deliverable: a written report and remediation roadmap rather than ongoing operations. If you need an advisory engagement to design the fix, see our cloud security consulting practice; if you need adversary-emulation to prove exploitability beyond configuration findings, schedule a penetration testing engagement; and for the broader controls catalogue we benchmark against, see our deep-dive on cloud infrastructure security services. Opsio's security audit services cover your full attack surface: on-premises infrastructure, cloud environments across AWS, Azure, and GCP, web applications, network architecture, identity systems, and security operations processes. We benchmark against CIS Controls, NIST Cybersecurity Framework, cloud provider Well-Architected Frameworks, and industry-specific requirements to produce a quantified, prioritised picture of your security maturity using established scoring methodologies.
Without regular security assessments, organisations accumulate configuration drift, orphaned accounts, shadow IT, and unmonitored attack surfaces that compound over time. A cloud environment that was secure at deployment degrades as teams make ad-hoc changes, new services are provisioned without security review, and compliance requirements evolve. The cost of a security assessment is a fraction of the cost of discovering your gaps through a breach.
Every Opsio security assessment includes automated scanning using CIS benchmark tools, manual expert review of architecture and configurations, stakeholder interviews covering security operations and incident response, compliance gap analysis against your specific regulatory requirements, a quantified maturity scorecard, and a prioritised remediation roadmap with effort estimates and business impact ratings for each finding.
Common security assessment challenges we solve: cloud environments that have never been audited against CIS benchmarks, organisations preparing for ISO 27001 certification or SOC 2 audit that need gap analysis, post-migration security validation confirming cloud environments are properly hardened, M&A due diligence requiring independent security evaluation, post-incident forensic investigation to determine root cause and prevent recurrence, and NIS2 compliance assessments for essential and important entities.
Following security assessment best practices, our engagement methodology combines automated tooling with expert manual review to catch both systematic configuration issues and architectural weaknesses that tools alone miss. We use CIS Benchmarks, NIST CSF, AWS Well-Architected, and cloud-native assessment tools selected for your environment. Whether you need a focused cloud security assessment, a full enterprise security audit, or incident forensics investigation, Opsio delivers actionable findings — not just a list of vulnerabilities.

IT & Cloud Security Assessment — Audit, Benchmark, Remediate — FAQ
What is a cloud security assessment?
A cloud security assessment is a systematic evaluation of your AWS, Azure, or GCP environment's security configuration against established benchmarks like CIS Cloud Benchmarks and cloud provider best practices. It covers IAM policies, network security, encryption, logging, storage permissions, and service-specific configurations. The output is a detailed findings report with risk ratings and a prioritised remediation roadmap. Unlike automated scanning alone, a proper assessment combines tooling with expert manual review to catch architectural weaknesses and business logic issues.
How much does a security audit cost?
A focused cloud security assessment for a single cloud environment costs $5,000-$12,000. A full enterprise security audit covering infrastructure, multi-cloud, applications, and network architecture ranges from $15,000-$35,000. Digital forensic investigations are scoped and priced separately at $10,000-$30,000 depending on incident complexity. Compliance gap analysis for ISO 27001, NIS2, or SOC 2 is typically $8,000-$18,000. We provide fixed-price quotes after a free scoping call. Many clients bundle assessments — for example, combining a cloud security audit with a compliance gap analysis at a reduced rate — to gain a comprehensive view of both their security posture and regulatory readiness.
How long does a security assessment take?
A focused cloud security assessment of a single environment takes 1-2 weeks. A comprehensive enterprise security audit covering infrastructure, multi-cloud, and applications takes 3-4 weeks including stakeholder interviews and architecture review sessions. Forensic investigations vary from 1-4 weeks based on incident scope and evidence volume. Reports are delivered within 48 hours of assessment completion. For urgent requirements, we offer accelerated timelines with parallel workstreams. The timeline depends on the number of cloud accounts, network segments, and applications in scope. We work closely with your team to schedule interviews and access without disrupting daily operations.
What is the difference between a security assessment and a penetration test?
A security assessment evaluates your security posture broadly — configuration review, compliance gap analysis, architecture review, and maturity scoring. It asks 'how well are we protected?' A penetration test is an offensive exercise where ethical hackers attempt to exploit specific vulnerabilities. It asks 'what can an attacker actually achieve?' Both are essential: assessments provide breadth and compliance evidence, while pen tests provide depth and proof of exploitability. Opsio delivers both services. For maximum value, we recommend starting with an assessment to identify systemic weaknesses, then following with targeted penetration testing focused on the highest-risk areas identified during the assessment phase.
Do I need a security assessment for ISO 27001?
Yes — ISO 27001 requires risk assessment and gap analysis as part of implementing an Information Security Management System. Our security assessment maps your current controls against all 93 Annex A controls in the 2022 version, identifies gaps, and provides the evidence base for your Statement of Applicability and risk treatment plan. Many organisations use our assessment as the foundation for their entire ISO 27001 certification project. The assessment output includes a prioritised remediation roadmap showing which controls to implement first based on risk severity, and estimated effort for each gap so you can plan resources and timelines accurately.
What frameworks do you assess against?
Our security audit methodology benchmarks against CIS Controls and CIS Cloud Benchmarks for AWS, Azure, and GCP, NIST Cybersecurity Framework, AWS/Azure/GCP Well-Architected Frameworks, ISO 27001 Annex A, SOC 2 Trust Service Criteria, PCI DSS, NIS2 Article 21, HIPAA Security Rule, and CMMC. We recommend the most relevant frameworks based on your industry, regulatory obligations, and customer requirements. For most European organisations, we assess against a combined ISO 27001 and NIS2 baseline. For companies selling to US enterprise customers, we add SOC 2 criteria. This tailored approach ensures the assessment focuses on controls that matter most for your business context.
How often should we conduct security assessments?
We recommend annual comprehensive security audits at minimum, with quarterly cloud security assessments for rapidly changing environments. Post-migration security reviews are essential after any cloud migration or major infrastructure change. Regulatory frameworks like NIS2 and PCI DSS require regular assessments. Post-incident assessments validate your improved posture after remediation. Continuous CSPM monitoring between formal assessments catches configuration drift in real time. Many clients adopt a rotating schedule — assessing cloud infrastructure one quarter, application security the next, and compliance posture the following — so that every domain receives focused attention throughout the year without overwhelming budgets.
What is included in a forensics investigation?
Our digital forensics service includes evidence preservation following legal chain-of-custody procedures, disk and memory forensics using industry-standard tools such as EnCase, FTK, and Volatility, attack chain reconstruction from initial access to impact, root cause determination, indicator of compromise extraction for future detection, affected data and system scope identification, and comprehensive documentation suitable for regulatory reporting, legal proceedings, or insurance claims. We also provide expert witness support when forensic findings need to be presented in legal or regulatory proceedings, and our evidence handling procedures meet the standards required for admissibility in European and international jurisdictions.
Can you assess multi-cloud environments?
Yes — multi-cloud assessment is a core capability. We assess AWS, Azure, and GCP environments using each provider's native assessment tools and CIS benchmarks, providing a unified view of your security posture across all cloud providers. Our reports highlight cross-cloud inconsistencies and provide a unified remediation roadmap that addresses all environments systematically. For example, we often find that organisations apply strong IAM policies in their primary cloud but have weaker controls in secondary environments. Our cross-cloud comparison identifies these gaps and establishes consistent security baselines across all providers to eliminate blind spots.
What happens after the assessment?
After report delivery, we conduct a findings walkthrough with your technical and leadership teams. We prioritise remediation into immediate action for critical findings, short-term actions within 30 days, and medium-term actions within 90 days. Optionally, Opsio can perform the remediation for managed environments and conduct a re-assessment to verify fixes. Many clients transition from assessment to ongoing managed security services, ensuring their improved posture is maintained continuously. We also provide a follow-up check-in four weeks after delivery to review remediation progress, answer technical questions, and adjust priorities if your risk landscape has changed.
