Protect Your Business With Expert Cybersecurity
The average cost of a data breach reached $4.45 million in 2023 according to IBM, with the figure rising to $5.13 million for organisations that lacked a security incident response plan. Attackers are professionalised, patient, and increasingly using AI to automate reconnaissance and craft targeted phishing campaigns. Yet most organisations still treat cybersecurity as a compliance checkbox rather than an operational discipline — running annual penetration tests, checking boxes on questionnaires, and hoping the firewall holds. Opsio's cybersecurity consulting takes a risk-based approach. We start by understanding your business — what data you hold, what systems are critical, what compliance frameworks apply, and what your actual threat landscape looks like. From there, we assess your technical security posture through vulnerability assessments, penetration testing, configuration reviews, and architecture analysis. Every finding is prioritised by business impact and exploitability, not just CVSS score, because a medium-severity vulnerability on your payment system matters more than a critical finding on a test server.
Beyond assessment, we design and implement security improvements: incident response plans, security awareness training, endpoint protection deployment, network segmentation, identity management hardening, and security monitoring. Our goal is a security programme that improves continuously — not a one-time audit that expires the moment the report is delivered.
What We Deliver
Risk Assessment & Gap Analysis
Comprehensive evaluation of your security posture against ISO 27001, NIST CSF, NIS2, and industry-specific frameworks. We identify gaps in policies, processes, and technical controls with risk-ranked remediation priorities aligned to your business context.
Penetration Testing
External, internal, web application, and API penetration testing conducted by OSCP and CEH certified testers. We simulate real-world attack scenarios to identify exploitable vulnerabilities before attackers do, with detailed reports including proof-of-concept exploits and remediation guidance.
Incident Response Planning
Development of incident response plans, playbooks, and escalation procedures tailored to your organization. Tabletop exercises and red team simulations validate your team's readiness. We ensure plans meet GDPR 72-hour and NIS2 24-hour notification requirements.
Security Architecture Design
Design of defence-in-depth security architectures covering network segmentation, zero-trust access, endpoint protection, email security, and data loss prevention. Architecture reviews for cloud environments, hybrid infrastructure, and application security.
Compliance & Certification Support
End-to-end support for ISO 27001 certification, SOC 2 readiness, NIS2 compliance, GDPR technical measures, and PCI-DSS validation. We prepare documentation, implement controls, and support you through the audit process.
Security Awareness Training
Custom security awareness programmes including phishing simulation campaigns, role-based training modules, and executive security briefings. Measurable improvement in employee security behaviour tracked through simulated attack metrics.

Cybersecurity Consulting Services FAQ
What is cybersecurity consulting?
Cybersecurity consulting is a professional service that helps organisations identify, assess, and mitigate cyber risks. This includes risk assessments, penetration testing, security architecture design, compliance alignment, incident response planning, and security awareness training. Opsio provides end-to-end cybersecurity consulting tailored to your industry, threat landscape, and regulatory requirements.
How often should we conduct penetration testing?
Best practice is annual penetration testing at minimum, with additional tests after significant infrastructure changes, application releases, or security incidents. Regulated industries (finance, healthcare) often require quarterly or semi-annual testing. Opsio recommends combining annual comprehensive penetration tests with continuous vulnerability scanning for ongoing visibility.
What is the difference between a vulnerability assessment and penetration testing?
A vulnerability assessment uses automated tools to scan for known vulnerabilities and misconfigurations. Penetration testing goes further — human testers actively attempt to exploit vulnerabilities, chain findings together, and simulate real attack scenarios. Opsio provides both: vulnerability assessments for broad coverage and penetration testing for depth and real-world attack simulation.
How do you help with NIS2 compliance?
Opsio maps your current security posture against NIS2 requirements including risk management measures, incident reporting obligations, supply chain security, and business continuity. We identify gaps, implement technical and organisational controls, develop the required policies and procedures, and prepare your incident reporting capability for the 24-hour initial notification and 72-hour detailed report requirements.
