Specialist cyber security services

Penetration Testing and Security Assessment

Independent penetration testing provides an objective view of your security posture by safely identifying vulnerabilities before attackers do. 

DotSec’s senior testing team will manage the assessment of your network, application, cloud and mobile environments, helping you understand real-world risk and prioritise remediation based on impact.

We work closely with your team to ensure findings are clearly explained, actionable, and aligned with your risk appetite and business objectives.

Managed SOC, SIEM and MDR

Detecting and responding to security incidents requires more than tools. DotSec provides managed SOC, SIEM and MDR services that combine expert monitoring, alert triage, investigation and reporting. Clients gain increased visibility across their environment and improved confidence that potential threats will be identified and managed appropriately.

Our managed service supports internal IT and security teams by reducing noise, improving detection quality, and providing independent assurance that potential attacks are not being overlooked.

Secure Configuration and System Hardening

Misconfigured systems remain one of the most common causes of compromise. DotSec helps organisations define, implement and verify secure configuration standards across Windows, Linux, macOS, M365, cloud platforms and mobile devices. Our approach aligns with recognised benchmarks and frameworks while remaining sensitive to operational requirements.

We help you standardise security controls, reduce attack surface, and maintain ongoing assurance through measurement and review.

Essential Eight Uplift and Assessment

The ASD Essential Eight continues to shape baseline cyber security expectations across Australia. 

DotSec works with organisations to assess current maturity, develop realistic uplift plans, and verify progress against target maturity levels.

Our consultants understand that every environment is different. We help ensure Essential Eight controls are implemented in a way that supports your risk profile, technical environment and operational constraints.

ISO 27001 and Security Governance

DotSec supports organisations seeking to establish, improve or certify an Information Security Management System under ISO 27001

Our consultants assist with risk assessment, control selection, policy development and assurance activities to help ensure your governance approach is practical, risk-based and demonstrably effective.

We also assist with broader security governance, including security reviews, risk workshops and executive reporting.

PCI DSS and Payment Security

Handling cardholder data requires strong, evidence-driven controls. 

DotSec works with merchants and service providers to understand PCI DSS obligations, reduce assessment scope where appropriate, and implement controls that satisfy both compliance and real-world security outcomes.

Our consultants are experienced in both technical security and compliance reporting, helping you prepare for assessment with clarity and confidence.
