Top Cyber Security OEMs for Smart Cities

A smart city is now a very large IT and OT estate. Cameras, traffic signals, water pumps, streetlights, building management systems and the Integrated Command and Control Centre (ICCC) all sit on networks, and each one is a possible way in. CERT-In’s Cyber Security Guidelines for Smart City Infrastructure, issued in February 2025, ask city bodies and their vendors to put controls in place for asset inventory, network segmentation, identity and access, logging and incident response.^[1]

That raises a practical question for SPVs, municipal corporations and building owners: which security vendors actually cover these areas? This post looks at twelve cyber security OEMs whose products map to the problems a city or a large campus faces. It is Trisim’s view, built only from the companies’ official pages and reputable coverage. It is not a ranking, and no company is included because of a paid placement or a partnership claim.

What a smart city needs to protect

Before looking at vendors, it helps to split the problem into layers. Most city and building security programmes need cover for:

• Endpoints and servers. The workstations, video servers and application servers in the ICCC and data centre.
• Identities. Operator, administrator, vendor and machine accounts, especially privileged ones with remote access.
• Networks. Firewalls and segmentation between the IT network, field networks and the internet.
• OT and IoT devices. PLCs, controllers, BMS panels, sensors and cameras that can’t run normal security agents.
• Monitoring. A security operations centre (SOC) that collects logs and responds to alerts.

No single vendor covers all of this equally well. Our earlier post on cyber risks in smart buildings covers why the OT layer is often the weakest.

CrowdStrike: endpoints, identity and now OT

CrowdStrike is a US-listed company best known for its Falcon platform, which it describes as protecting endpoints, cloud workloads, identity and data.^[2] For city systems, two recent moves matter. First, in November 2025 it announced new Falcon for XIoT capabilities for operational technology, including zero-touch discovery of industrial assets without dedicated sensors or intrusive scans, and visibility into how OT devices talk across network segments.^[3] CrowdStrike says Falcon for XIoT covers OT, industrial control systems and IoT environments, with a sensor built for legacy ICS systems.^[4]

Second, on 20 January 2026 CrowdStrike announced a planned in-country regional cloud for India, alongside Saudi Arabia and the UAE, so that organisations can run Falcon with data resident in the country.^[2] For Indian government buyers, data residency is often a deciding factor, so it is worth confirming the go-live status and data location in writing before any procurement.

Saviynt: identity governance and privileged access

Saviynt provides a cloud-native identity platform covering Identity Governance and Administration (IGA), Privileged Access Management (PAM), Just-in-Time Access and Identity Security Posture Management.^[5] The company says it has a 600-plus strong R&D and support centre in India.^[5] In March 2026 it appointed Exclusive Networks as a distributor across Asia-Pacific markets including India,^[6] and on 22 October 2026 Express Computer reported its partnership with Saint Fox to expand identity security offerings in India.^[7]

Why does identity matter for a city? Many city systems are run by several contractors, each with remote access to servers, cameras or controllers. CERT-In’s recent advisory on AI agents, which we covered in our post on CERT-In’s AI agent alert, found that exposed credentials and open admin panels were a common entry point. Controlling who has privileged access, and for how long, closes much of that gap.

TechBridge: an Indian SOC platform

TechBridge Consultancy Services is a Gurugram-based company that offers two platforms: ObservaX for infrastructure monitoring and AIOps, and CyberSIO, which it describes as a ‘SOC-in-a-box’ combining SIEM, SOAR, user behaviour analytics, identity and access tools, and patch management.^[8][9] The company’s government page lists smart city, data centre monitoring and SLA management among its use cases, and describes monitoring for surveillance, smart lighting, environmental sensors and public address systems from a central command centre.^[10] The details here come from the company’s own pages; we could not find independent media coverage to add.

Fortinet: firewalls and rugged OT networking

Fortinet’s FortiGate firewalls are widely used for network security. For field and OT sites, the company offers FortiGate Rugged firewalls, rugged switches and 5G gateways, which it says comply with over 70 industry standards.^[11] In March 2025 Fortinet said its FortiGuard OT Security Service covered over 3,300 OT protocol rules, nearly 750 OT intrusion prevention rules and 1,500 virtual patching rules, the last of which help protect legacy systems that can’t be patched quickly.^[12] Fortinet also publishes guidance on securing smart transportation infrastructure.^[13] For a city, this is the layer that separates junction controllers, pumping stations and camera networks from each other and from the internet.

Claroty: cyber-physical systems and BMS

Claroty focuses on cyber-physical systems (CPS), with asset inventory, exposure management, network protection, secure access and threat detection, available in the cloud (xDome) or on premises (Continuous Threat Detection).^[14] Its Team82 research on building management systems analysed more than 467,000 devices in 529 organisations and found that 75% of organisations were managing BMS devices with known exploited vulnerabilities.^[15] That finding matters to anyone running hospitals, data centres, malls or government campuses. In India, PwC India and Claroty announced an alliance for OT and connected-environment cybersecurity on 9 September 2026.^[14]

Nozomi Networks: OT and IoT visibility for cities

Nozomi Networks offers OT and IoT security with a page dedicated to smart cities. It covers asset inventory for OT, IoT and building automation devices, threat detection, and building automation system security, with passive, agentless and active data collection options.^[16] Mitsubishi Electric completed its acquisition of Nozomi Networks in January 2026; the companies said Nozomi would continue to operate under its own brand with a vendor-agnostic approach.^[17]

Seqrite: an Indian endpoint and zero-trust option

Seqrite is the enterprise security brand of Quick Heal Technologies, headquartered in Pune according to the company’s LinkedIn page. The page describes Seqrite as securing devices, applications, networks, cloud, data and identity.^[18] Its product range includes endpoint protection, endpoint detection and response (EDR), extended detection and response (XDR), Zero Trust Network Access, mobile device management and a data privacy platform, and it has a dedicated government page focused on data protection compliance and digital sovereignty.^[19]

Seqrite is already a familiar name in Indian public procurement. For example, a March 2026 GeM bid by IREL (India) Limited, under the Department of Atomic Energy, was for renewal of Seqrite endpoint security, with four qualified sellers.^[20] For SPVs that prefer an Indian OEM for ICCC and office endpoints, it is worth a look; it is not an OT-specific tool, so it would sit alongside the OT platforms below rather than replace them.

Palo Alto Networks: firewalls and OT research

Palo Alto Networks describes itself on its LinkedIn page as a global cybersecurity leader, with over two million followers.^[21] In February 2026 it published joint research with Siemens and the Idaho National Laboratory, based on telemetry from over 61,000 firewalls in OT environments, which found a 332% increase in unique internet-exposed OT devices and services, with nearly 20 million OT-related devices visible on the public internet.^[22]

In India, the Data Security Council of India (DSCI) announced on its LinkedIn page that Palo Alto Networks was the AI Cyber Security Partner for GovSec 2026, held in New Delhi on 23 April 2026, where the company ran a session on zero trust network access for ‘Bharat’s digital sovereignty’.^[23] For cities, the exposure research is the key point: cameras, controllers and BMS panels reachable from the internet are exactly what segmentation should prevent.

Cisco: Cyber Vision and industrial networking

Cisco Cyber Vision is built for industrial organisations and critical infrastructure. Cisco says it gives a live OT asset inventory, detects malicious traffic and abnormal behaviour, helps enforce IEC 62443 zones and conduits, and includes zero trust remote access. Its sensors can run inside selected Cisco switches and routers, so no separate appliances are needed, adding only 2% to 5% extra network traffic according to Cisco.^[24]

Cisco also has Indian smart city history. In December 2019, Cisco and the Gurugram Metropolitan Development Authority announced an Integrated Command and Control Centre for traffic management and city surveillance, with Cisco firewall and Stealthwatch tools for threat detection.^[25] On its LinkedIn page, Cisco describes its focus as securely connecting organisations in the AI era.^[26] Where a city’s field network already runs on supported Cisco switches, embedded OT visibility is a practical option to evaluate.

Check Point: firewalls and IoT Protect

Check Point’s LinkedIn page says it protects over 100,000 organisations worldwide through its Infinity Platform.^[27] For connected devices, its IoT Protect product discovers and maps IoT and OT devices, applies zero-trust segmentation, and blocks attacks with virtual patching and more than 300 IPS signatures; Check Point names IP cameras, smart elevators and industrial controllers among the devices it covers.^[28]

India matters to the company. In an August 2026 interview with Business Standard, CEO Nadav Zafrir said India is among Check Point’s top five markets and its biggest R&D hub outside Israel, with over $100 million invested in the last few years and five offices in the country.^[29]

Honeywell: OT cybersecurity for buildings and plants

Honeywell Cyber Insights is an OT security product that Honeywell says provides asset visibility, near real-time threat detection and vulnerability management across industrial and building OT networks. It is vendor-agnostic and can integrate with process control or building systems.^[30] That makes it a natural fit for BMS-heavy sites such as hospitals, airports and government campuses.

Honeywell’s 2026 OT Cybersecurity Benchmark Report, released on 22 September 2026, surveyed more than 600 industrial cybersecurity leaders. It found that 88% described their OT programmes as mature, but only 21% had a complete OT asset inventory, only 33% had fully integrated OT into a central SOC, and only 20% continuously monitored IoT devices such as cameras and sensors.^[31] The company has highlighted the same visibility gap on its LinkedIn page.^[32]

Tenable: OT exposure management and BMS

Tenable calls itself ‘the exposure management company’ on its LinkedIn page and says it serves more than 44,000 customers.^[33] Its OT security product added expanded support for BACnet and SNMP in version 3.16, giving visibility into HVAC, security cameras, lighting and access controls in smart buildings. It combines passive monitoring with queries in devices’ native protocols.^[34]

In April 2026, Industrial Automation India reported Tenable’s VM-native OT discovery engine inside the Tenable One platform, which maps OT and IoT assets without extra hardware, sensors or agents.^[35] For cities that already scan IT assets, this is a way to bring BMS and field devices into the same vulnerability view.

What this means for city and building owners

• Start with the CERT-In guidelines. Map each control in the smart city guidelines to a product or process you already have, and buy only for the gaps.^[1]
• Know your assets first. You can’t protect what you can’t see. OT and BMS discovery tools give the inventory every other control depends on.
• Lock down vendor access. Use privileged access tools with time-bound, recorded sessions for integrators and OEM support teams, instead of shared passwords and permanent VPNs.
• Segment the network. Keep cameras, BMS, traffic systems and the ICCC in separate zones, with firewalls between them and nothing exposed directly to the internet.
• Ask about data residency. For cloud-based security tools, get the data location and processing region in writing, and check them against the DPDP Act and your department’s rules.
• Plan the SOC. Decide who watches the alerts at 2 am. Many ICCCs already run around the clock; our Control Rooms guide covers how they are organised, and a security desk can often sit alongside.

Trisim’s view

In Trisim’s view, there is no single ‘best’ cyber security OEM for a smart city. The right mix depends on the layer: endpoint and identity tools for the ICCC and data centre, rugged firewalls and segmentation for field sites, and OT-aware monitoring for BMS and industrial devices. Cities that start with an honest asset inventory and tight vendor access will get more from any of these platforms.
