Zscaler launches solution to enable zero-trust security for IoT, OT devices
Zscaler
on Wednesday launched the 'Zscaler Cellular' solution for
Internet of Things
(IoT) and Operational Technology (OT) devices, eliminating the need for additional software or virtual networks for secure connections.
In a statement, the company said that the solution delivers 'resilient connectivity' by ensuring IoT and OT devices automatically connect to any mobile network globally, while providing zero attack surface by isolating each device on its 'private island', with all connections securely routed through the Zscaler platform.
'With the introduction of
Zscaler Cellular
, we have extended the power of the Zero Trust Exchange to IoT and OT devices with an easy 'install and go' SIM card that securely connects to any cellular network,' said Nathan Howe, group VP of emerging technologies at Zscaler. .
As enterprises rapidly deploy IoT/OT devices across diverse environments, traditional firewall and VPN-based security models do not adequately meet the demands of today's mobile and distributed organisations, leaving devices exposed to cyber threats.
Legacy methods rely on costly infrastructure that cannot scale, while mobile networks can not enforce zero-trust principles by design, resulting in security blind spots and expanding attack surfaces.
Through solutions like Zscaler Cellular and Zscaler Cellular Edge, and collaborations with telecom companies such as
NTT
, enterprises gain
managed security services
that address the unique challenges of securing distributed, cellular-connected environments.
Zscaler Cellular will become available globally in August 2025. The solution is already in use by leading organisations, including Sandvik and Maverick Transportation.
'By leveraging Zero Trust with cellular networks, Zscaler helps eliminate longstanding visibility and control gaps that have plagued enterprises for years. It's the first solution I've seen that brings cloud-scale security to every connected device with the simplicity of activating a SIM,' said Zeus Kerravala, founder and principal analyst, ZK Research.

India's edge data centre capacity may triple to 210 MW by 2027: ICRA
NEW DELHI: India's edge data centre capacity is expected to triple from 60-70 MW in 2024 to nearly 200-210 MW by 2027, led by established players such as RailTel and telecom companies to serve emerging technologies such as fifth-generation (5G) networks and the Internet of Things (IoT), according to the latest report released by ICRA on Thursday. During the same period, the edge data centre capacity as a percentage of India's total data centre capacity may increase from 5% to 8%, the ratings agency found. Edge data centres are smaller, decentralised facilities located closer to end-users and devices, compared to typically large and centralised traditional data centres. These smaller data centres, located mainly in tier-2 and tier-3 towns and cities, facilitate real-time data processing with minimal latency, making them suitable for innovative technologies. ICRA, however, noted that India is a relatively new entrant in the data centre market. 'Excluding the edge data centre capacity used for captive purposes by one of the large data centre operators, the current edge data centre capacity as a percentage of total capacity is as low as 1%,' it said. Globally, edge data centres accounted for 10% of the overall data centre capacity of 50 GW at the end of December 2024. The US leads the edge data centre market with a 44% share, followed by Europe, the Middle East and Africa (the EMEA) region at 32% and Asia Pacific region at 24%. 'With the expanding cloud ecosystem of India, traditional data centres will keep fuelling mass-scale computing, artificial intelligence (AI), and cloud workloads, and edge data centres will facilitate real-time processing and localised services,' said Anupama Reddy, vice president and co-group head (corporate ratings), ICRA. Traditional and edge data centres are expected to operate in the hub-and-spoke model to enhance efficiencies across sectors such as healthcare, banking, agriculture, defence, and manufacturing, among others, Reddy added. ICRA cautioned that despite the promising outlook, some key challenges for edge data centres include security vulnerabilities due to remote deployments, rapid technological changes that risk obsolescence, a shortage of skilled professionals in remote areas, and interoperability issues with traditional data centres. 'The rentals for edge data centres are anticipated to be on the higher side compared to traditional data centres, as they will be catering primarily to retail customers against enterprise/hyperscale customers for traditional data centres,' Reddy said. The relatively higher capex cost per MW for an edge data centre compared to a traditional data centre is expected to be compensated by higher rentals. 'Established DC players and entities like RailTel, telcom operators are likely to lead the edge data centre expansion in India,' she said.

India's Edge Data Centre Capacity Set To Triple By 2027: Report
Reported By : Last Updated: July 25, 2025, 12:15 IST Currently, edge data centres account for about 5% of India's total data centre capacity. India's edge data centre industry is poised for exponential growth, with capacity projected to triple to 200-210 megawatts (MW) by 2027 from the current 60-70 MW, according to the latest report by credit rating agency ICRA. This surge is expected to be driven by the rapid adoption of emerging technologies such as the Internet of Things (IoT), 5G, augmented and virtual reality (AR/VR), and generative artificial intelligence (AI). Edge data centres are smaller, decentralised facilities located closer to end-users and devices. Unlike traditional centralised data centres, which are typically large and centralised, edge facilities enable real-time data processing with minimal latency (the delay between a user action and the corresponding system response). This makes them ideal for supporting emerging technologies such as IoT, 5G, AR/VR, and GenAI. These new-age applications and technologies are forecasted to grow significantly in the medium term, resulting in an increased demand for edge data centres. Currently, edge data centres account for about 5% of India's total data centre capacity. However, when excluding capacity used for captive purposes by a major player, the share drops to as low as 1%. ICRA expects this figure to grow significantly, with edge data centres expected to make up 8% of the total capacity by 2027. P: Projected (Source: ICRA Research) 'Edge data centres differ from traditional data centres in multiple parameters like size, location, scale, time taken to construct, capex cost per MW, and proximity to the end user," said Anupama Reddy, vice-president and co-group head (corporate ratings) at ICRA. 'In the Indian context, traditional data centres and edge data centres are complementary pillars of digital infrastructure." Reddy said India's data infrastructure will increasingly adopt a 'hub-and-spoke' model. Traditional data centres will continue to support large-scale computing and AI workloads, while edge data centres will handle real-time, location-sensitive operations in sectors such as healthcare, banking, agriculture, Defence, and manufacturing. Globally, edge data centres are estimated to account for around 10% of the total data centre capacity, which stood at 50 gigawatts (GW) as of December 2024. The United States currently dominates the global edge data centre market with a 44% share, followed by the Europe-Middle East-Africa (EMEA) region at 32%, and the Asia-Pacific (APAC) region at 24%. India remains a relatively new entrant but is expected to accelerate its adoption in the coming years. Despite a promising outlook, the growth of edge data centres is not without challenges. Security vulnerabilities are a concern due to their deployment in remote Tier II and Tier III cities. Moreover, a shortage of skilled professionals in these regions, rapid technological shifts that could render infrastructure obsolete, and interoperability issues with traditional data centres pose significant hurdles. 'Rentals for edge data centres are anticipated to be on the higher side compared to traditional data centres, as they cater primarily to retail customers, unlike traditional centres which serve enterprise and hyperscale clients," Reddy noted. 'The higher capital expenditure per MW for edge data centres is expected to be offset by these higher rentals." Swipe Left For Next Video View all ICRA also highlighted that established data centre players, as well as entities such as RailTel and telecom operators, are likely to lead India's edge data centre expansion over the next few years. As digital demand continues to rise across urban and rural India, edge data centres are set to play a critical role in ensuring faster, more efficient digital services, marking a new chapter in the country's technological advancement.
