A decade ago, the main cybersecurity concern for primary enterprises and industrial firms related to their laptops, desktops and servers. Now, the risk landscape has become exponentially more diverse. While we are arguably still in an early phase of IoT adoption, the Internet of Things is beginning to become ubiquitous in the modern business world. Many organizations, for instance, have wireless smart TVs in their boardrooms and wireless surveillance cameras and smart lighting overhead. Other organizations have had to contend with various IoT-related security worries, ranging from unauthorized drones spying on industrial facilities to rogue connected devices on their premises. IoT technology is also found in everything from hospitals, water purification facilities to smart city initiatives.

The multifaceted threat landscape has given rise to a cottage industry of startups and midsized companies offering to help industrial and enterprise companies stay safe in a quickly evolving environment. The situation has also won the attention of networking and security heavyweights such as Cisco, Symantec and McAfee, which offer to help businesses stay safe as the field of network security grapples with an IoT-driven Wild West phase. 

Here, we present 25 trailblazing IoT security companies, presented alphabetically. All the companies on this list either have a dedicated IoT security business or they leverage innovative connected technology to help thwart security risks, whether they are stopping an unauthorized person from accessing the network or a drone from entering an organization’s property.

Criteria for ranking included firms’ degree of focus on enterprise and industrial IoT security and the innovation and market traction of their product offerings. When available, we factored into the ranking reviews of the companies’ technology and workplace culture. The companies

1. Armis

Founded in 2015, startup Armis recently received considerable attention after its discovery of BlueBorne, a Bluetooth-based attack vector. Although the firm offers an IoT security platform, it has also done a significant amount of research on IoT device security and maintains a database including more than 4 million connected devices.

The company offers an agentless security platform tailored for IoT devices. In the words of CEO and co-founder Yevgeny Dibrov, Armis aims to help enterprise companies end the “IoT blind spot” that exists when organizations have poor awareness of the devices on their network. “If you look at an average organization today, they can’t see around 40% of their connected devices in their environments,” Dibrov said. “If you went back five to seven years ago, the main wireless devices in an office were laptops. Today, the diversity of wireless devices is huge: security cameras, smart TVs, wireless printers and more.”

Armis technology can also help spot active threats and rogue connected devices in an enterprise setting, which is one of the simplest attack vectors for cybercriminals. The technology is installed in more than 100 organizations across the United States.

Dibrov and Chief Technology Officer Nadir Izrael, also co-founder, previously worked at Unit 8200, the cyber-Intelligence service of the Israeli Intelligence Corps, which is analogous to the National Security Agency in the United States. Earlier this year, Gartner recognized the company on its Cool Vendors in Security for Midsize Enterprises list.

2. Bastille

Bastille leverages patented software to help with enterprise IoT security. Having noticed that three-quarters of IoT technology use radios, it is the first company to specialize in mitigating the risk of what it terms “Internet of Radios,” or unsecured connected devices emitting frequencies from 60 MHz to 6 GHz within an organization. Many enterprise and industrial companies already have devices that use RF communications but are often not aware of the extent of the security risk those technologies pose. The need for the company’s technology can be seen, for instance, in an April tornado siren hack in Dallas.

The company has created a cloud-based platform focused on sensing, identifying and locating threats from RF-enabled devices. The platform supports more than 100 distinct communication protocols.

Bastille’s technology can be used to help mitigate attacks and spot rogue devices (including rogue cell towers) but can also be useful in doing forensic analysis following a cyberattack.

The company’s core engineering office is in Atlanta. Bob Baxley, who ran the software-defined radio lab at Georgia Tech, leads the company’s engineering efforts.

Bastille also focuses on research and discovered MouseJack and KeySniffer, vulnerabilities that illustrate the risk posed by modern wireless protocols.

Bastille is working both with the U.S. Department of Defense and the Department of Homeland Security.

3. CENTRI Technology

CENTRI Technology’s Internet of Things Advanced Security (IoTAS) platform is a software-only platform designed to both secure and compress data in motion and at rest. The technology is based on research from the University of Mississippi. The company’s chief scientist, Luis Paris, invented and patented cache-mapping compression, a data compression algorithm that enables fast and secure data transfer. The technology was the basis of Paris’ doctoral studies. CENTRI was created around a technology transfer with the university. Typically used in computer processors, cache memory speeds access to memory. Paris, however, explained in his doctoral thesis that cache memory can be used for real-time data compression and data security for connected devices. “We think about data as the be-all and end-all,” said Vaughan Emery, CENTRI’s CEO and president. “We have a platform that provides security from chip to cloud, whether that is private cloud, public cloud or hybrid.”

The platform provides device identity, secure session, key management and data cryptography at rest and in transport. “There is no central [hardware security module] required with our platform,” Emery said, which makes it easier for companies to scale IoT applications securely. The company’s technology also makes it possible for users to search encrypted data. “Best practices drive that all data should be encrypted. The problem is that encrypted data has a tendency to break application stacks or BI or analytics systems that customers are using,” Emery explained. “With our platform, customers can search that encrypted data and they can extract data that remains encrypted. As it passes to the application, our process will decrypt it based on all of the proper access controls.”

4. Cisco

Cisco has done as much as anyone to popularize the concept of the Internet of Things, but also has developed a substantial portfolio of products and services suitable for IT, as well as IoT, security. “We see the network as a critical control point for IoT security,” said Shaun Cooley, vice president and CTO for IoT and Industries at Cisco. The considerable variability between IT and OT environments, however, requires the networking giant to tailor its approach. In network security, there is a foundational principle known as the CIA triad, which emphasizes confidentiality, integrity and availability of information technology. In IT environments, the focus is generally in that order, but in an OT environment, it is reversed. “Availability trumps everything else in most OT environments,” Cooley added. “Integrity is usually second, and confidentiality is usually third. Depending on the environment, it could be a close third or a very distant third.” When the company designs a hardware firewall for an OT environment, it works to prioritize network availability. For instance, the company can configure firewalls to continue to allow packets to be routed even in the case of a power outage.

Network management specialties applicable to IoT from Cisco include access control, policy enforcement, intrusion prevention, security management and endpoint security. The company also offers an IoT Threat Defense portfolio, which ensures network segmentation for IoT devices and provides secure remote access, network and traffic visibility, custom security services, planning services, risk assessment, and incident response.

The company’s Network Intuitive effort can also help enterprise and industrial companies anticipate and secure IoT projects. “When a new device tries to connect to the network, the Network Intuitive works with that device through open standards we have set up with device manufacturers,” Cooley said. “The network instructs the device to describe its intended use of the network. Based on that intended use, the Network Intuitive can define things like microsegmentation and security access control lists to allow that device to have the minimum access it needs to the network to do what it is supposed to do without creating any possible ways for outside influence to come in. Older devices that don’t support these open standards are identified by Cisco’s identity services engine and can have similar microsegmentations created for them.”

5. Claroty

Claroty specializes in industrial IoT cybersecurity, helping managers of industrial facilities and critical infrastructure protect their networks from nation-states, criminals and hacktivists. The company, which was launched as a startup out of Israel's Team8 foundry, delivers a network monitoring platform that allows for continuous monitoring, threat detection and response. The platform is specifically designed for industrial control systems, SCADA networks and other industrial infrastructure. This summer, the startup announced the general availability of its Secure Remote Access platform, which is an addition to its existing OT security offerings that enables secure remote access for third parties such as industrial control systems equipment vendors. Claroty’s platform supports Ethernet and serial networks as well as standard industrial protocols and proprietary protocols from prevalent industrial vendors. The company's platform continuously scans for threats while also providing a robust enterprise management console. Claroty's customer base stretches across seven continents and includes prominent names in the Fortune 500. Its partner base includes companies like Schneider Electric and Rockwell Automation.

6. DarkMatter

One thing that sets DarkMatter apart from other cybersecurity firms is its focus on resiliency within digital environments. “To some extent, this is quite a disruptive outlook, as we assume breach of digital systems,” said Eddie Schwartz, executive vice president of cyber services at DarkMatter. “Rather than working on tools and measures to prevent compromise altogether, we choose to engender a culture of planning and mitigation to cyberthreats, which we believe are all but inevitable in one guise or another.”

The company offers security assessments and incident response services for IoT-related projects across a range of verticals, ranging from smart cities to critical infrastructure and beyond. Based in the United Arab Emirates, DarkMatter has an international customer base including government agencies and enterprise businesses. The company has R&D facilities in UAE, Canada and China. 

DarkMatter also has a comprehensive research group capable of assessing cyber risks present in the hardware and software of IoT devices. “We have a hardware laboratory that is unique in the commercial world,” said Schwartz. “We are one of the few labs in the world that can break down IoT devices, take them down to bare metal and look for vulnerabilities. Those vulnerabilities might be in the chips themselves.” 

The company works with its clients to develop a systems-oriented view of cybersecurity and offers the software-based “Cyber Risk Scorecard,” which enables organizational leaders to assess potential risks of cybersecurity vulnerabilities and use that data to make informed decisions. The software dashboard also allows users to map an organization’s current risk state to desired outcomes, while also assessing its risk level compared with that of other organizations.  

DarkMatter also offers a cyber resiliency platform, which models in real time the impact of a security incident across an organization or city.

The company offers auditing services to customers, verifying that they comply with regulatory standards.

DarkMatter has won several awards including the 2016 Top Vendor in Enterprise Security prize at the Global Enterprise Connect (GEC) Awards and was named the 2017 Gulf Business Company of the Year. “Our innovative outlook to cybersecurity and the view to raising defenses to cyber resilience were recognized last year when we were selected as one of just 30 companies to participate in the Dubai Future Accelerators program, which was aimed at solving real challenges faced by Dubai government agencies through the use of innovative technologies,” explained Tawanda Chihota, the corporate communications lead at the company.

A subsidiary of DarkMatter known as Pegasus is using big data analytics to help Dubai’s police force fight crime. Pegasus is collaborating with Huawei to deploy secure smart city applications.

7. Dedrone

This startup is unique in that it specializes in airspace security — detecting drones that invade protected zones whether at an airport or above a stadium or industrial facility. Dedrone’s platform combines hardware sensors and machine learning software, providing early warning, classification of and mitigation against drone threats. Its hardware can be mounted to facades or windows and identifies approaching drones using visual, acoustic and frequency sensors. Noise, movement pattern, silhouette, and RF and Wi-Fi signals are processed and evaluated with the intelligent DroneTracker software. DroneTracker’s correlation and analysis of this information classifies approaching drones and triggers alarms to alert security staff. Third-party sensors, such as surveillance cameras, radar, jammers or other countermeasures, can be integrated with the platform.

Dedrone has an active and growing installed base. Its most notable references include the Clinton-Trump presidential debates, a Suffolk County correctional facility in New York, the royal family of Qatar, the New York Mets stadium and the World Economic Forum in Davos, Switzerland. Dedrone was founded in 2014 by CEO Joerg Lamprecht, CTO Rene Seeber and Chief Operating Officer Ingo Seebach. The company is backed by investors including Felicis Ventures; Menlo Ventures; and John Chambers, former CEO and chairman of Cisco Systems.

8. Dell EMC

Dell may traditionally be best known as a hardware vendor, but the company offers an array of security offerings throughout its various subsidiaries ranging from RSA to SecureWorks to VMware and beyond. Dell itself offers a variety of security services tailored for networks, data, endpoints, identity and access management. From an IoT perspective, the company recently announced a realignment that would harmonize its security offerings across its subsidiaries.

“We have things like NSX from VMware that focuses heavily on microsegmentation and new types of security concepts [such as app defense],” said Ray O’Farrell, CTO of Dell subsidiary VMware.

The Dell subsidiary and encryption progenitor RSA serves 30,000 customers internationally. The RSA algorithm, which launched in 1977, proved to be a pioneering public key cryptosystem. Today, it is widely used for encryption included in many IoT applications. The RSA Archer platform, which has received accolades from Gartner and Forrester, helps organizations with operational risk management.

From an IoT perspective, RSA is looking closely at how risk applies to IoT implementations starting at the edge. “In conjunction with Dell, RSA believes that the security battleground for IoT is going to be at the edge. It is the ‘things’ themselves and the gateways they connect to within the enterprise,” said Brian Girardi, vice president, product architecture and research at RSA. One of RSA’s core competencies is identity and access management, which for IoT implementations often spans from the things and the edge up a core data center or cloud services. RSA also has a visibility and detection business known as the RSA NetWitness suite, which is designed to help organizations determine if they have been breached.

SecureWorks, a public company with Dell as the majority owner, offers a SaaS platform, SecureWorks Client Portal, that is designed to help monitor and manage security threats and incidents. The business offers managed security services for organizations wishing to offload cybersecurity whereas RSA focuses more on security products and research.

9. EY

EY offers an array of cybersecurity consulting services, operating a dedicated unit that focuses on the risk posed by Internet of Things deployments, including both industrial and consumer implementations.

Aleksander Poniewierski, Ph.D., leads IoT globally for EY Advisory and is a cybersecurity professional with over 20 years of experience in this space. “With IoT, we force the concept of security by design,” Poniewierski said. “With IoT, we need to think about security from the beginning and infuse the concept of security into initial discussions regarding products, philosophy and the business case.”

The company’s combined financial and security prowess gives it an advantage as an advisor to enterprise, industrial and government clients. Instead of acting like a traditional IT security guardian, EY can serve as an IoT advisor, helping clients simultaneously refine the business case for an IoT project while also mapping out a strategy for locking it down.

25. ZingBox

Most devices should behave predictably. If they behave erratically, there is likely something wrong. ZingBox takes this basic concept and applies machine learning and artificial intelligence to it to determine what normal behavior for IoT devices is, monitor that behavior over time and trigger alerts if there is, say, an anomalous traffic pattern that would indicate a security problem. 

“One aspect that is interesting about ZingBox is that it is an agentless technology,” said Scott Darling, president of EMC’s corporate development and venture capital. “Let’s say you are monitoring medical equipment. You can’t install agents on it because it violates the licensing rules from the government about how you affect the internal software,” Darling said. “In addition, vulnerability scanners applied to IoT devices can sometimes cause those devices to fail. ZingBox overcomes these limitations by using AI and machine learning to help detect viruses on medical equipment by detecting suspicious traffic behaviors. The technology can help identify the ‘personality’ or profile of a given IoT device and track that its behavior does not change as a result of a cyberattack.”

Founded in 2014, the company is focused on IoT devices and has developed a significant business for connected medical devices. ZingBox can help companies monitor connected devices that weren’t designed with security in mind.

ZingBox was named to Gartner’s 2017 Cool Vendors in IoT Security list.
