Firewall and protection
Network security is the cornerstone of any information security. Regardless of the size of the business, the network is exposed to external attacks, uninvited access, malware and misconfigured services on a daily basis.
An effective firewall and additional security mechanisms are essential for a stable, secure and reliable operation of the entire IT system.
By deploying advanced firewall solutions and protection policies, we help businesses create a secure network environment that prevents unwanted access and protects business-critical data.

is the basis for integrated information security
Advanced network protection with sophos firewall and Cosco NGFW solutions
Today’s modern business network is no longer protected by a basic firewall. Businesses
use remote access, cloud services, web applications, production systems, servers, WiFi
networks, VPN connections and a host of external integrations. Any of these points can become a security
risk if the network is not properly designed, segmented and monitored.
At In.Sist, we help businesses create a reliable, transparent and secure network environment with
advanced firewall solutions from Sophos and Cisco. Our goal is not just to install a firewall,
but to provide comprehensive network protection that reduces the risk of intrusions, outages, access abuse, the spread of
malware and unauthorised use of business systems.
A properly configured firewall is one of the most important security points in a company. It protects access to
Internet, servers, users, remote locations, business applications and sensitive data. It also allows
to monitor traffic, users, applications, VPN connections and security events.
Why a basic firewall is no longer enough today
Attacks on businesses are increasingly targeted, automated and covert. The traditional firewall, which only checks ports, IP addresses and basic rules, is often no longer sufficient. Modern protection must also identify applications, suspicious behaviour, dangerous web connections, intrusion attempts, infected devices, improper access and unusual network traffic.
That’s why we use next-generation solutions like Sophos Firewall and Cisco NGFW, which go far beyond basic traffic filtering. They include advanced network traffic inspection, intrusion protection, web filtering, VPN access, application monitoring, malware protection, reporting, central management and security policies tailored to the way your business works.
Our services include

It provides advanced network protection, web traffic control, VPN access, IPS protection, network segmentation, application filtering and central management
When deploying Sophos Firewall solutions, we take care of selecting the right model, designing rules, configuring security policies, setting up VPN connections, arranging user access, network segmentation, protecting servers and setting up reporting. We pay particular attention to ensuring that the system is transparent, stable and easy to maintain in the long term.
Deployment of Cisco NGFW solutions
The Cisco NGFW is suitable for enterprises that require advanced network protection, high availability, powerful traffic processing and integration with existing Cisco infrastructure. Cisco solutions provide advanced threat protection, application monitoring, IPS protection, URL filtering, advanced malware protection and centralised security policy management.
Cisco NGFW solutions are recommended for enterprises with complex infrastructures, multiple sites, complex networks, data centres, production environments or high control and compliance requirements. We provide design, implementation, policy migration, connection to the existing network, access configuration, event monitoring and technical support.
IDS and IPS intrusion protection
Intrusion detection and prevention systems help identify suspicious traffic, attempts to exploit vulnerabilities, attacks on servers, dangerous connections and other activities that can compromise your company’s security.
A properly configured IPS must not only detect threats, but also be adapted to the real environment of the company. That’s why we set the rules thoughtfully to reduce false alarms while maintaining effective protection of critical systems.
VPN and secure remote access
Remote access is a necessity today, but it must be properly protected. We set up secure VPN connections for employees, outsourcers, business partners and connections between multiple company locations.
You can arrange SSL VPN, IPsec VPN, inter-office connections, access to servers, access to internal applications and restrictions by user, device or location. We follow the principle of least privilege, which means that the user only accesses what they really need.
Network segmentation
Many companies still have too many open internal networks where users, servers, WiFi devices, cameras, production systems and hosted devices can communicate with each other without clear restrictions. This poses a major risk as an infection or attack can quickly spread throughout the network.
We help you organise your network segmentation with VLANs, access policies and clear rules between different parts of the infrastructure. We can separate servers, users, WiFi, guests, production, cameras, administration and other systems. This reduces the possibility of an attacker moving laterally across the network.
Web filtering and application control
Advanced web traffic filtering can limit access to dangerous, inappropriate or commercially unnecessary websites. We can also control the use of applications such as remote access, streaming services, social networks, cloud services, communication tools and other applications that impact security or productivity.
The aim is not to restrict users for no reason, but to make the use of the internet in the company clear and safe.
Protecting servers and business applications
The firewall must also protect internal and publicly accessible servers. We provide secure service publishing, access restriction, NAT rules, administrative access protection, server network segregation and
traffic control to business applications.
We pay special attention to systems such as ERP, WMS, MES, SQL servers, web applications, remote access, file servers, virtualization environments and other business critical systems.
Monitoring, reports and maintenance
A firewall is not a system that is set once and forgotten. Security policies need to be regularly reviewed, updated and adapted to changes in the company.
We offer regular maintenance, security policy review, performance monitoring, event analysis, software upgrades, VPN connection verification, log review and recommendations for improvements. So your firewall remains effective even as your network, users and business needs change.

Sophos Firewall or Cisco NGFW
Choosing the right solution depends on the size of the business, the complexity of the network, the number of users, the number of
sites, the speed of the internet connection, the security requirements and the existing infrastructure.
Sophos Firewall is often an excellent choice for businesses that want strong protection, good visibility,
easy management and an effective performance/value ratio.
The Cisco NGFW is suitable for more complex networks, larger organisations, environments with existing Cisco
infrastructure and enterprises that need advanced management, integration and scalability options.
We help you make the right choice by analysing your current situation, reviewing your needs and developing a proposal that
is suitable for your environment.
First, we review the current network, existing security settings, internet connections, servers,
VPN access, Wi-Fi networks, VLAN structure, and user workflows. Based on this, we prepare a
proposal for improvements and select an appropriate firewall and VPN solution.
We then take care of implementation, migration of existing rules, performance testing, documentation,
system handover and follow-up support. Our focus is on ensuring that the solution is technically correct,
secure, easy to understand and usable in day-to-day business.
Our approach
Remote access and VPN
Modern business requires reliable and secure access to data from anywhere – from the office, at home or in the field. Remote working, connecting different company locations and mobile access to key business systems (ERP, WMS, servers, documentation) have become standard.
But to access this data securely, it is essential to use encrypted connections, authentication and properly configured access policies.
By setting up VPN solutions, we enable businesses to have secure, stable and controlled access to their IT systems, without exposing sensitive data to the public internet and without compromising on security.
Establish secure VPN connections
Implementation of IPsec, SSL and site-to-site VPN tunnels to securely connect employees and business units to the central infrastructure.
Authentication and access management
MFA authentication, rights management with RBAC models, integration with Active Directory, and Zero-Trust approach.
Network segmentation and separation
Creating separate network zones, segmenting users, isolating remote devices and increasing security and transparency.
Monitoring and support
24/7 monitoring of VPN connections, access analytics, regular updates, troubleshooting and technical support.
