Internet access is essential in modern workplaces but can lead to distractions and security risks. To combat this, many employers use web filtering to block websites deemed unproductive or inappropriate.

The primary goal of web filters is to maintain employee productivity by limiting personal internet use during work hours. Additionally, they aim to reduce cybersecurity risks associated with high-risk sites. As cybercrime increases and data breaches become more costly, employers are enhancing web security policies to protect their organizations.

To better understand web filtering trends, the aggregated data from NordLayer’s DNS filtering service was analyzed. This research, which does not include identifiable business or user information, reveals the most commonly restricted website categories, helping create secure and productive work environments.

Restricting internet access is crucial for boosting cybersecurity and productivity. Our research identified that 72% of employers block malware and adult content sites, while 43% block gambling websites. These findings are consistent with other studies showing widespread internet restrictions in corporate settings. For instance, a survey found that 64% of employees reported their company used a firewall to limit web access, though 40% bypass these controls using mobile data.

A 2018 study indicated that web filtering increases with company size: 96% of large businesses with over 1,000 employees restrict at least one online service, compared to 92% of midsize companies and 81% of small businesses. The same study estimated that 58% of employees spend over four hours per week on non-work-related sites without filtering, with 26% spending more than seven hours weekly on personal browsing. This translates to significant productivity losses, with full-time staff wasting 26 paid days annually.

While web filtering is already widely adopted, there are compelling reasons for more organizations to implement it as part of their cybersecurity and acceptable use policies.

From a security standpoint, restricting access to malware sites and other high-risk categories is crucial. Malware infections can lead to data breaches, disruptions, and financial losses. With the rise in cybercrime, web filtering serves as a preventive measure.

Beyond security, unrestricted internet access can lead to legal liabilities if employees access inappropriate or illegal content using company devices. This can result in regulatory violations, harassment issues from explicit material, or data exfiltration through file-sharing services.

Productivity is another key factor. Limiting personal internet use during work hours helps minimize distractions and increase focus on job duties. These benefits make a strong case for integrating web filtering into cybersecurity strategies.

Balancing secure and productive internet access requires careful implementation. While some may see content filtering as restrictive, it is becoming essential to protect networks, data, and devices. Proper configuration and clear use policies can create a safer online workplace without hindering legitimate business activities.

Finding this balance is crucial for maximizing the internet’s business utility while safeguarding critical assets. Overly restrictive filtering that blocks essential work resources or categories like social media can frustrate employees and disrupt workflows.

The best approach involves thorough planning and customizing filtering rules to align with an organization’s needs and culture. Flexibility for temporary access and whitelist approvals for legitimate business purposes is essential. Collaboration between human resources, IT, and security departments is necessary to develop and communicate reasonable use policies.

Monitoring and adjusting filter effectiveness are also important. As new cybersecurity threats emerge and business needs evolve, filtering rules may need updates. Employee feedback can provide valuable insights into potential overblocking issues..
