Rising Numbers of Cyberattacks

The number of cyberattacks in the country is significantly rising due to its weak cyber-defence practices and the old practice of outsourcing the management and development of security systems to outside vendors. This is driving the adoption of cybersecurity solutions among businesses in Japan.

Increase in Remote Work

The shift to remote work is surging incidences of malware, phishing, breaches, identity thefts, and ransomware attacks, boosting the demand for robust cybersecurity solutions.

Favourable Government Initiatives

Amid the rising incidences of cyberattacks, the Japanese government is establishing active cyber defence strategies to better monitor suspicious activities, improve information sharing with the private sector, and partner with domestic communication companies for better monitoring of suspicious activities.

Evolution of the Internet of things (IoT)

The evolution of the Internet of things (IoT) and the growing number of IoT devices are necessitating the implementation of robust cybersecurity measures to reduce the risk of network attacks and data breaches.

Japan Cyber Security Market Trends

There is rising adoption of smart devices and IoT gadgets in different end-use sectors, ranging from transportation to healthcare, among others. Organisations are also leveraging the Internet of things (IoT) technology to facilitate predictive maintenance and remote monitoring as well as reduce their operational complexity.

The expansion of IoT ecosystems opens up the risk of security threats such as malicious software, DDoS attacks, and insecure communication pathways, leading to compromised data and widespread disruption. This is prompting organisations to strengthen IoT cybersecurity through strategies such as regular updates, strong encryption and authorisation, and network segmentation and monitoring, among others.
