As businesses increasingly rely on digital infrastructure, the threat of cyberattacks looms larger than ever. Malicious actors are constantly devising new ways to infiltrate networks, steal data, and disrupt operations. In this landscape, having a secure and reliable internet connection is non-negotiable. That’s where Airtel Internet for Office comes in.
Airtel Internet for Office is more than just a high-speed connectivity solution. It’s a comprehensive package that includes enterprise-grade security features to protect your business from online threats. Central to this security stack is Cisco DNS Security, a powerful tool that blocks malicious domains and IP addresses at the DNS layer. In the following sections, we’ll explore how this integration works and why it’s a game-changer for network security.
What is Cisco DNS Security?
Cisco DNS Security is a cloud-based security solution that operates at the Domain Name System (DNS) layer. It’s part of the larger Cisco Umbrella platform, which provides a first line of defence against internet-based threats.
Here’s how it works:
- When a user on your network tries to access a website, their device sends a DNS request to resolve the domain name into an IP address.
- Cisco DNS Security intercepts this request and checks the requested domain against a constantly updated database of known malicious sites.
- If the domain is flagged as malicious, the connection is blocked before it can be established, preventing any potential harm.
This proactive approach stops threats at the earliest possible stage, minimising the risk of data breaches, malware infections, and other security incidents.
Key Features of Cisco DNS Security
Cisco DNS Security offers a range of features that make it a powerful tool for protecting business networks:
- Comprehensive Threat Intelligence: Cisco DNS Security leverages threat intelligence from Cisco Talos, the world’s largest non-governmental threat research network. Talos analyses millions of malware samples and terabytes of data daily, ensuring Umbrella stays ahead of emerging threats.
- Broad Coverage: The solution blocks access to malicious domains associated with phishing, ransomware, botnets, and other common threats.
- Visibility and Reporting: Cisco DNS Security intercepts DNS requests and checks them against a constantly updated threat intelligence database. Connections to malicious domains, phishing sites, and botnets are blocked at the DNS level, preventing threats from infiltrating your network. This proactive approach stops attacks before they cause damage, without impacting user experience.
- Easy Deployment: The cloud-based architecture allows for seamless integration with existing networks, including SD-WAN environments.
By incorporating Cisco DNS Security into Airtel Internet for Office, businesses can enjoy enterprise-grade protection without the complexity and cost of traditional security solutions.
How Airtel Office Internet Leverages Cisco DNS Security
Airtel Office Internet seamlessly integrates Cisco DNS Security into its enterprise-grade offerings. This combination delivers:
Automatic Threat Mitigation
- DNS requests from all connected devices are automatically filtered through Cisco’s secure servers.
- Malicious domains and IP addresses are blocked, preventing access to harmful content and reducing the attack surface.
Enhanced Endpoint Security

- This multi-layered approach protects individual devices from viruses, malware, and ransomware, complementing the network-level security provided by Cisco DNS Security.
Effortless Implementation
- Deploying Cisco DNS Security with Airtel Office Internet requires minimal configuration.
- Simply redirecting DNS requests to Cisco’s servers activates the protection, without the need for complex setup or hardware installation.
Real-World Impact of DNS Security
DNS attacks are a growing concern for businesses of all sizes. In fact, nearly 90% of organisations worldwide have experienced DNS-related security breaches, with the average cost of such incidents reaching $950,000 in India.
By integrating Cisco DNS Security, Airtel Internet for Office helps businesses mitigate these risks and avoid the financial and reputational damage associated with security breaches. Here are some of the key benefits:
