Stop threats at the edge of your network
Your firewall is the first and most important line of defence between your business and the internet. A misconfigured or outdated firewall is one of the most common reasons businesses get breached. CoreSecTech designs, deploys, and maintains enterprise-grade firewall and network security for offices in Nagpur — covering Sophos, Fortinet, pfSense, MikroTik, and Cisco. We don’t just plug in a box; we build a security policy around how your business actually works, then monitor it so threats are blocked before they reach your servers and staff.
What firewall and network security covers
A proper firewall deployment is far more than turning on a default ruleset. We start by mapping your traffic — which applications your team uses, which services need to be reachable from outside, and which should never be exposed. From there we build least-privilege rules so only the traffic you actually need is allowed. Our service includes next-generation firewall installation and configuration, intrusion prevention (IPS/IDS), web and application filtering, VPN setup for remote staff and branch offices, network segmentation to contain breaches, and continuous logging so every connection is accountable. We also harden the devices themselves — changing default credentials, disabling unused services, and keeping firmware patched.
Threat protection that works around the clock
Attacks don’t wait for office hours. We configure your firewall to actively block known malicious IPs, phishing domains, ransomware command-and-control traffic, and intrusion attempts in real time. Geo-blocking restricts access from regions you never do business with, and deep packet inspection catches threats hidden inside otherwise normal-looking traffic. When something unusual happens, alerts reach our team so we can respond — often before you would have noticed anything was wrong.
Secure remote access for your team
Hybrid and remote work only stays safe when remote access is done properly. We set up encrypted VPN tunnels — site-to-site for connecting branch offices and client-based for individual remote workers — so staff can reach internal resources without exposing them to the open internet. Combined with multi-factor authentication, this means a stolen password alone is not enough for an attacker to get in.
Network segmentation that limits damage
Flat networks are dangerous — once an attacker gets in, they can reach everything. We segment your network with VLANs and firewall zones so that guest Wi-Fi, staff devices, servers, CCTV, and VoIP are all isolated from one another. If one segment is compromised, the others stay protected, and the blast radius of any incident shrinks dramatically.
