Cybersecurity FAQ
Questions about your security?
Understand how Montagne approaches cybersecurity, infrastructure protection and digital risk.
A cybersecurity assessment examines your systems, networks, infrastructure, data and existing security controls to identify vulnerabilities, risks and areas where your security posture can be strengthened.
Network protection can involve secure configuration, access controls, segmentation, monitoring, endpoint protection and ongoing vulnerability management. The right approach depends on your infrastructure and operational environment.
Effective incident response starts with identifying and analysing suspicious activity. Appropriate containment, investigation, remediation and recovery measures can then be taken to reduce disruption and strengthen protection against similar incidents.
Data protection can include access controls, encryption, secure storage, backup strategies, monitoring and appropriate data-handling practices. Controls should be aligned with the sensitivity and importance of the information being protected.
No security measure can guarantee that an organisation will never experience an attack. However, layered security controls, vulnerability management, secure backups, access protection, monitoring and incident response planning can help reduce exposure and limit the impact of ransomware.
No. Businesses of different sizes rely on networks, cloud services, devices, applications and sensitive information. Cybersecurity measures should be proportionate to the technology, data and risks associated with each organisation.
