The world is full of machines and gadgets, readily participating in the race to automation, though this race incorporates a hoard of convolutions. IoT is the escape route to push these convolutions at bay, making IoT security testing an essential aspect. The interconnecting machines’ network that supports effortless data exchange is popularly termed IoT (Internet of Things). It is a rapid-growing technology making its significance in almost every sector and has improved the productivity, efficiency, and pliability of the operations and workflow of industries. 

In 2018, the global market size of IoT security was valued at $8,472.19 million and it is forecasted to hit 73,918.82 million by 2026, expanding at a CAGR of 31.20%.

No doubt, IoT devices and systems have brought a huge difference, in a positive manner, in the work process of modern-age industries. They also have exposed these industries to significant risks and that’s where the need for IoT security occurs.

Are you worried about hackers bypassing your firewall? In this newsletter, let’s figure out the reason behind it.

What is IoT Security?

The epoch of hi-tech technologies and IoT devices added value to the operations of the company by elevating productivity, accessibility, and scope for innovation. At the same time, it has raised concerns about the cybersecurity of these devices and technologies.

Nowadays, threat actors can compromise and hack any device from Google Assistant to the smart appliances at your home and hold great power to harm you. For this reason, organizations rendering IoT security testing and prevention remedies have pulled all the limelight. 

IoT security is a process of arm-guarding IoT devices and systems with advanced tools to ensure secure data transmission, prevent hacking of the devices, and ensure the data security standards are being followed correctly. 

How IoT Security Can Protect Your Business?

Every month, hackers launch more than 5000 cybersecurity malware/attacks targeting IoT devices specifically. Due to this, approx. 60% of small-scale businesses get shut down post being attacked by con artists. 

However, seeking IoT security must not cost a fortune to any business organization instead it has to be cost-effective yet efficient and proactive.

These are a few infrastructure utilities that businesses with secured IoT devices and systems leverage:

• Mitigate the probability of hacks and data breaches
• Receive early compliance with respective standards
• Alleviate monetary losses and cost of negligence 
• Minimize reputational harm & maintain reliability
• Elevate the security of IoT and the agility of business operations.

If businesses give priority to IoT security, they ensure a range of benefits that ultimately aid in business growth and customer reliability.
