9 Essential Firewall Statistics for 2021

A cybersecurity breach takes 279 days to rectify on average. Your computer is attacked in some way every 39 seconds. Firewall software is one way organizations can protect against this constant threat. 

However, the way these tools protect you is changing in 2021. 

The shift to remote work forced firewall vendors and clients to adapt. More people working online created infinitely more weak points. This is why organizations invest so heavily in the firewall market today. 

The statistics below show the current state of the firewall market, its potential future, and how customers are interacting with this vital category.

Firewall News and Developments

The past year has seen significant innovation and investment in the firewall and cybersecurity markets. Here are the biggest fundraising and valuation events from 2021: 

Palo Alto and Google

A match made in heaven? Palo Alto Networks has expanded their partnership with Google Cloud, seeking to innovate on network security issues. These two organizations plan to incorporate Palo Alto’s threat detection with Google’s cloud expertise to improve their user experiences. These innovations will see both companies taking advantage of their respective successes, at the benefit of customers. 



This security startup aims to address DNS or code-injection base attacks to complement companies’ existing firewalls. They have raised $8.25 million in investments to advance broader threat detection and protection capabilities. These comprehensive, multilayered strategies are crucial to securing modern attack surfaces, in addition to and beyond traditional firewall security



Another company innovating from within, CheckPoint’s new Quantum Security Gateways aim to expand firewall access to more use cases. The company is a strong innovator for enterprise-level companies with cloud-based management needs. Their recent advancements are seeing the company expand across the firewall market.


Firewall Trends to Watch in 2021


Work From Home Changes Everything

Remote work is forcing firewall providers to evolve. On-site only firewalls are obviously insufficient for the protection needs of many companies. This means more investment in cloud-based firewall-as-a-service software. These types of firewalls do not require expensive investment in every physical location where staff are present. They also offer scalability and, most crucially, mobility. 


IoT Driving Firewall Development

Smart TVs, watches, and even fridges are now storing valuable data through the Internet of Things. These are potential points of vulnerability that firewall software is adapting to.

Companies are unlikely to start installing firewalls on their breakroom freezer, but the threats are real and growing. DDoS, Web-exploit kits, malware, and application-level threats are all evolving as fast as their defensive technology. The vast majority of attacks happen because of human error, a lack of firewall tech, or incorrectly configured security. With this in mind, a trend in firewall security is the focus on covering all your bases. As the IoT expands, organizations must cover all vulnerable points. 


Human Error Still Plagues Us

88% of data breaches are a direct result of human error. Of all the market trends we’ve explored at TrustRadius, this is one of the most consistent. Organizations must focus on employee education and clear guidelines. However, the security training many have experienced are actually not doing much good. As more and more valuable content is stored online, they should probably be scaled up with dedicated security awareness training software.
