How does a Firewall protect your network?

Many have compared firewalls to the front door of your network. For modern workloads, the traffic demands are so great we need to think much bigger. The firewall is more like an enormous suspension bridge for a superhighway that connects your island (your network) to the mainland (the internet). The internet is filled with suspicious and malicious characters that want access to your network, but it's also filled with necessary and extremely helpful resources your organization needs to access. Traffic is constantly flowing between your network and the internet and the firewall is the first point of security to keep unwanted traffic out. It discerns who should access the network and who shouldn’t. Even when traffic is permitted it goes through multiple levels of inspection to try and ensure only safe traffic is allowed to your network.

How do we help?

NSI brings decades of firewall expertise to help organizations design, configure, and optimize the firewall to your environment. Our team sizes and selects the right models, configures to best practices, and builds tailored policies for access control, intrusion prevention, malware defense, DNS protection, identity enforcement, and security intelligence. We also enable the encrypted visibility engine, which inspects encrypted traffic without compromising privacy. Finally, we integrate the firewall with compatible tools such as supported endpoint and NAC security tools. The result is a firewall deployment that provides strong protection.

Powered by Cisco

Our email security solution is built on Cisco Secure Email Threat Defense, a platform designed to protect against today’s most advanced email-based attacks. By leveraging Cisco Talos, threats are identified all around the globe, day and night, and turned into protections that keep your environment safe.

Most email security products capture telemetry based on email only, but Cisco adapts information from a full stack of security controls – including firewalls, EDR, web security, DNS security, and a host of other sources. This allows rapid policy creation that blocks threats and prevents malicious actors from ever reaching your users.

NSI has extensive experience and certification in configuration and management of Cisco Secure Firewalls.

A Modern Approach to Security

Email Security is a powerful security tool on its own, but its capabilities are put to even greater use when working alongside and in-tandem with other solutions.

We recommend you create a unified defense system through integrations that provide complimentary insights and controls such as firewalls, endpoint protection, and threat intelligence. NSI follows a simple assess, protect, and detect/respond model to quickly categorize and discuss your digital assets and the tools you have in place to keep them secure.
