Security audits and vulnerability assessments for resilient, protected systems
We assess and strengthen digital platforms for organisations who need to identify risks and secure their environments, without sacrificing performance, usability or scalability.
Who this is for
You need visibility into security risks
Uncertainty around vulnerabilities, exposure or compliance gaps.
You’re preparing for a launch, audit or compliance review
Ensuring systems meet required standards before going live.
You want to proactively reduce risk
Identifying and addressing issues before they become incidents.
What we help solve
Practical problems we see on security programmes-and how we address them.
Unknown vulnerabilities in your systems
Security gaps go undetected until exploited. We conduct structured security audits and vulnerability assessments-clear understanding of risks and priorities.
Lack of visibility across infrastructure and applications
Multiple systems create blind spots. We review infrastructure, applications and integrations holistically-a complete view of your security posture.
Misconfigured environments and access controls
Poor configurations create unnecessary exposure. We identify configuration and permission issues-reduced attack surface and improved control.
Compliance and governance gaps
Systems don’t align with required standards. We assess against relevant frameworks and best practices-improved compliance readiness.
No clear remediation plan
Issues are identified but not resolved effectively. We provide prioritised, actionable remediation guidance-a structured path to improved security.
Why Tonic / why this approach
- Practical, risk-focused assessmentsWe prioritise real-world impact, not just theoretical issues.
- End-to-end visibility across systemsLooking beyond isolated components to the full ecosystem.
- Clear, actionable outputsFindings translated into prioritised remediation steps.
- Aligned to development and infrastructureSecurity integrated with how systems are built and deployed.
- Ongoing support and improvementSecurity treated as a continuous process, not a one-off exercise. Security is embedded into delivery and operations, not a standalone checklist.

Selected work
Representative security outcomes-explore more in our work.
Infrastructure and application security audit
Enterprise organisation-audit, vulnerability assessment, remediation. Limited visibility into security risks addressed with critical vulnerabilities identified and fixes implemented.
Pre-launch security assessment
Growth-focused organisation-testing, validation, reporting. Need to ensure platform security before release met with a secure, compliant launch and reduced risk.
Built for real-world delivery
Infrastructure and cloud security
Secure environments across hosting platforms.
Application and API security
Protecting platforms, integrations and data flows.
Access control and identity management
Ensuring secure authentication and permissions.
QA and validation
Testing fixes and verifying improvements.
Compliance and governance alignment
Supporting regulatory and industry requirements.
Support and continuity
Ongoing security monitoring and optimisation.

Clear audit scope; missed vulnerabilities reduced.
Assessment and testing
We audit infrastructure, applications and configurations.
Identified risks and vulnerabilities; undetected issues reduced.
Analysis and prioritisation
We assess severity and impact.
Prioritised list of issues; misallocation of effort reduced.
Reporting and recommendations
We provide clear, actionable guidance.
Structured remediation plan; inaction or confusion reduced.
Remediation support
We assist in resolving identified issues.
Improved security posture; incomplete fixes reduced.
Ongoing monitoring and reassessment
We support continuous improvement.
Sustained security and resilience; new vulnerabilities over time reduced.
FAQs
What’s the difference between a security audit and a vulnerability assessment?
An audit reviews overall security posture, while a vulnerability assessment identifies specific weaknesses.
Do you provide penetration testing?
Yes-where required, we simulate real-world attack scenarios.
Can you assess cloud environments?
Yes-we review infrastructure across major cloud platforms.
Do you help fix the issues you find?
Yes-we provide remediation guidance and support implementation.
How often should we run security assessments?
Regularly, especially after major changes or releases.
Will this impact our live systems?
Assessments are designed to minimise disruption while identifying risks.
